Lived experience of a record wildfire season in the Northwest Territories, Canada.

Abstract: During the period of June–September 2014, the Northwest Territories (NWT) experienced its worst wildfire season on record, with prolonged smoke events and poor air quality. In the context of climate change, this study sought to qualitatively explore the lived experience of the 2014 wildfire season among four communities in the NWT. Our team conducted 30 semi-structured interviews in four communities (Yellowknife, N’Dilo, Detah, and Kakisa). Interviewees were purposively sampled to include a broad cross-section of backgrounds and experiences. Interviews were video recorded, and the audio portion of each interview was transcribed to facilitate analysis and theme generation. Interviewees reported how their experiences of evacuation and isolation as well as feelings of fear, stress, and uncertainty contributed to acute and long-term negative impacts for their mental and emotional well-being. Prolonged smoke events were linked to extended time indoors and respiratory problems. Livelihood and land-based activities were disrupted for some interviewees, which had negative consequences for mental, emotional, and physical well-being. Individual and community stories of adaptation and resilience prior to and during the summer, including the opening of indoor recreational spaces, were shared; however, there was consensus about the need for improved risk communication and coordination at the community and territorial levels to address similar events in the future. Coordinated community-based education, communication, and adaptation initiatives that are inclusive of local knowledge, values, and context are needed to address the expressed needs of community members associated with prolonged smoke events and wildfire seasons.

A critical analysis of obesity prevention policies and strategies

Abstract: OBJECTIVES: Public health policies have been criticized for promoting a simplistic narrative that may contribute to weight bias. Weight bias can impact population health by increasing morbidity and mortality. The objectives of this study were to: 1) critically analyze Canadian obesity prevention policies and strategies to identify underlying dominant narratives; 2) deconstruct dominant narratives and consider the unintended consequences for people with obesity; and 3) make recommendations to change dominant obesity narratives that may be contributing to weight bias. METHODS: We applied Bacchi’s “what’s-the-problem-represented-to-be?” (WPR) approach to 15 obesity prevention policies and strategies (1 national, 2 territorial and 12 provincial). Bacchi’s WPR approach is composed of six analytical questions designed to identify conceptual assumptions as well as possible effects of policies. RESULTS: We identified five prevailing narratives that may have implications for public health approaches and unintended consequences for people with obesity: 1) childhood obesity threatens the health of future generations and must be prevented; 2) obesity can be prevented through healthy eating and physical activity; 3) obesity is an individual behaviour problem; 4) achieving a healthy body weight should be a population health target; and 5) obesity is a risk factor for other chronic diseases, not a disease in itself. CONCLUSION: The consistent way in which obesity is constructed in Canadian policies and strategies may be contributing to weight bias in our society. We provide some recommendations for changing these narratives to prevent further weight bias and obesity stigma.

Physical and mental health inequalities among aging lesbian, gay, and bisexual Canadians: cross-sectional results from the Canadian Longitudinal Study on Aging (CLSA)

Abstract: International estimates suggest the presence of health inequalities among older sexual minorities (i.e., individuals who identify as lesbian, gay, or bisexual and are 65 years old or above). In this study, we investigated the presence of health inequalities among aging lesbian and bisexual females, as well as aging gay and bisexual males in Canada. We used baseline data from the Canadian Longitudinal Study on Aging (CLSA) Tracking and Comprehensive cohorts to cross-sectionally compare self-reported physical and mental health indicators by sex and sexual orientation. Within our analysis sample of 51,208 Canadians 45 years old and over, 2% (n = 1057) of respondents identified as lesbian, gay, or bisexual. Compared to heterosexual female peers, lesbian and bisexual females had greater odds of heavy drinking (AOR = 1.8, 95% CI = 1.3–2.4) and being a former smoker (AOR = 1.5, 95% CI = 1.2–1.9). Gay and bisexual males had greater odds of reporting a diagnosis of cancer (AOR = 1.5, 95% CI = 1.0–1.9) and currently smoking (AOR = 1.5, 95% CI = 1.1–2.0), compared to heterosexual males. Female and male sexual minorities had greater odds of reporting mood disorders (including depression) and anxiety disorders relative to heterosexual peers of the same sex. These findings highlight the importance of considering both sex and sexual orientation when developing approaches to support the physical and mental health of a diverse aging population in Canada.

Canadian mining and ill health in Latin America: a call to action.

Abstract: This commentary argues that Canada’s public and global health communities have a special ethical and political responsibility to act to reverse the harms associated with Canadian mining activities in Latin America and beyond through advocacy, research, and using their public voice. We begin with an overview of the direct and indirect health effects of mining, drawing especially on Latin America where 50-70% of mining activity involves Canadian companies. Then we examine the judicial, legislative, financial, and diplomatic contexts that make Canada such a welcome host and champion of the mining sector. Finally, we turn to the responsibility of the public and global health communities, offering concrete recommendations for using research, practical expertise public health solidarity networks, and political clout to speak out and advocate for policies that redress the harms caused by mining.

Drug checking at an electronic dance music festival during the public health overdose emergency in British Columbia.

Abstract: Shambhala is a 5-day electronic dance music (EDM) festival held in rural British Columbia that annually hosts between 15,000 and 18,000 people on a 500-acre ranch. The AIDS Network Outreach & Support Society (ANKORS) has provided harm reduction services throughout the duration of the festival since 2003, including point-of-care drug checking, which allows real-time testing of illicit substances to assess their composition. Drug checking results are provided directly to clients and displayed in aggregate on a screen for all attendees to see. In 2017, ANKORS added fentanyl checking to their repertoire of drug checking technologies for festivalgoers. Volunteers used a brief survey to collect information on what clients expected the samples to contain. Volunteers carried out drug checks and subsequently logged test results. ANKORS provided an amnesty bin at the tent for clients who chose to discard their substances. Of the 2683 surveys, 2387 included data on both the client’s belief and the actual test result. Clients were more likely to discard when the test result differed from their belief (5.16%) than when their belief was confirmed (0.69%). Discarding increased to 15.54% when the test could not clearly identify a substance and to 30.77% if the client did not have a prior belief of the substance. Of 1971 samples tested for fentanyl, 31 tested positive and 16.13% of clients discarded compared to 2.63% in the negative group. Drug checking services appeal to festivalgoers who, when faced with uncertainty, may discard their substances. This innovative harm reduction service allows for a personalized risk discussion, potentially reaching others via word-of-mouth and early warning systems.

Guelph Family Health Study: pilot study of a home-based obesity prevention intervention.

Abstract: To examine the feasibility and preliminary impact of a home-based obesity prevention intervention among Canadian families. Families with children 1.5–5 years of age were randomized to one of three groups: (1) four home visits (HV) with a health educator, emails, and mailed incentives (4HV; n = 17); (2) two HV, emails, and mailed incentives (2HV; n = 14); or (3) general health advice through emails (control; n = 13). Parents randomized to the 2HV and 4HV groups completed post-intervention satisfaction surveys. At baseline and post-intervention, parents reported frequency of family meals and their children’s fruit, vegetable, and sugar-sweetened beverage (SSB) intake. We assessed the children’s physical activity, sedentary behaviour, and sleep using accelerometers and their % fat mass using bioelectrical impedance analysis. Differences in outcomes at post-intervention, controlling for baseline, were examined using generalized estimating equations. Of the 44 families enrolled, 42 (96%) had 6-month outcome data. Satisfaction with the intervention was high; 80% were “very satisfied” and 20% were “satisfied.” At post-intervention, children randomized to the 4HV and 2HV groups had significantly higher fruit intake and children randomized to the 2HV group had significantly lower percentage of fat mass, as compared to the control. No significant intervention effect was found for frequency of family meals, the children’s vegetable or SSB intake, physical activity, sedentary behaviour, or sleep. Our results suggest that the delivery of a home-based intervention is feasible among Canadian families and may lead to improved diet and weight outcomes among children. A full-scale trial is needed to test the effectiveness of this home-based intervention. NCT02223234

Prevalence of problematic cannabis use in Canada: Cross-sectional findings from the 2013 Canadian Tobacco, Alcohol and Drugs Survey

Abstract: OBJECTIVES: Cannabis is the most widely used illicit substance in Canada. There exist a variety of tools to measure problematic characteristics of cannabis use; however, there is no consensus on the operational definition of “problematic use”. The current study sought to estimate the prevalence of problematic cannabis use in Canada, in terms of the kinds of problems Canadians report due to their cannabis use, the levels of harm associated with cannabis consumption, and potential differences among socio-demographic groups. METHODS: Cross-sectional, nationally representative data for Canadians were obtained from the publicly available Statistics Canada’s 2013 Canadian Tobacco, Alcohol and Drugs Survey (CTADS) ( n = 13 635). Binary logistic regression analyses were conducted to examine subgroup differences in patterns of cannabis use and problematic outcomes defined by the World Health Organization’s Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) tool embedded in CTADS. RESULTS: The findings indicate that, while 1 in 10 Canadians reported using cannabis in the past 3 months, only 2% of the sample of Canadians who reported using cannabis in the past 3 months were characterized as having a “high risk” of severe health or other problems. Canadian male respondents were more likely to report social problems than females and to be categorized as high risk. Youth and young adults between the ages of 15 and 29 consistently reported a greater prevalence of problems associated with their cannabis consumption than their older counterparts. CONCLUSION: A very small proportion of Canadians report using cannabis to a degree that is problematic. Approximately one in two young people reported using cannabis at some point in their lives, of concern given the negative health outcomes of early cannabis use. This study highlights the need for the development of more sensitive instruments to detect problematic cannabis use.

Beyond the grey tsunami: a cross-sectional population-based study of multimorbidity in Ontario.

Abstract: To determine volumes and rates of multimorbidity in Ontario by age group, sex, material deprivation, and geography. A cross-sectional population-based study was completed using linked provincial health administrative databases. Ontario residents were classified as having multimorbidity (3+ chronic conditions) or not, based on the presence of 17 chronic conditions. The volumes (number of residents) of multimorbidity were determined by age categories in addition to crude and age-sex standardized rates. Among the 2013 Ontario population, 15.2% had multimorbidity. Multimorbidity rates increased across successively older age groups with lowest rates observed in youngest (0–17 years, 0.2%) and highest rates in the oldest (80+ years, 73.5%). The rate of multimorbidity increased gradually from ages 0 to 44 years, with a substantial and graded increase in the rates as the population aged. The top five chronic conditions, of the 17 examined, among those with multimorbidity were mood disorders, hypertensive disorders, asthma, arthritis, and diabetes. Much of the common rhetoric around multimorbidity concerns the aging ‘grey tsunami’. This study demonstrated that the volume of multimorbidity is derived from adults beginning as young as age 35 years old. A focus only on the old underestimates the absolute burden of multimorbidity on the health care system. It can mask the association of material deprivation and geography with multimorbidity which can turn our attention away from two critical issues: (1) potential inequality in health and health care in Ontario and (2) preventing younger and middle-aged people from moving into the multimorbidity category.

Assessing health literacy among older adults living in subsidized housing: a cross-sectional study.

Abstract: This study aimed to assess functional health literacy levels among older adults living in subsidized housing in Hamilton, Ontario, and to assess the relationships between health literacy and other important health indicators, such as education level, age, ethnicity, body mass index (BMI), and self-reported health status. Older adults (n = 237) living in subsidized housing buildings in Hamilton, ON, were assessed using the NVS-UK as a measure of functional health literacy in addition to a health indicator questionnaire through structured interview. Health literacy levels were analyzed using descriptive statistics and logistic regression to determine relationships between health literacy levels and other health indicators. Participants’ mean age was 73 years, 67% were female, 70% were not educated beyond high school, and 91% were white. Over 82% of participants had below adequate health literacy levels using the NVS-UK. Multivariable logistic regression revealed significant relationships between functional health literacy and BMI, education level, and pain and discomfort levels. No significant relationships were found between health literacy level and age group, anxiety and depression levels, CANRISK (Diabetes risk) score, gender, marital status, mobility issues, self-care issues, self-reported health status, or performance of usual activities. As the population of older adults continues to grow, the appropriate resources must be available to both improve and support the health literacy level of the population. Future health research should gather information on the health literacy levels of target populations to ensure more equitable health service. This research provides a significant opportunity to better understand populations with health literacy barriers.

Cyberbullying victimization and its association with health across the life course: A Canadian population study.

Abstract: OBJECTIVES: To examine the prevalence of cyberbullying victimization (CV), its associations with self-reported health and substance use and the extent to which age moderates these associations. METHODS: We used the 2014 Canadian General Social Survey on Victimization ( N = 31 907, mean age = 45.83, SD = 18.67) and binary logistic regression models to estimate the strength of association between CV and health-related outcomes. RESULTS: The five-year prevalence of CV was 5.1%. Adolescents reported the highest prevalence of CV (12.2%), compared to all other adult age groups (1.7%–10.4%). After controlling for socio-demographic covariates, individuals exposed to CV had increased odds of reporting poor mental health (OR = 4.259, 95% CI = 2.853–6.356), everyday limitations due to mental health problems (OR = 3.263, 95% CI = 2.271–4.688), binge drinking (OR = 2.897, 95% CI = 1.765–4.754), and drug use (OR = 3.348, 95% CI = 2.333–4.804), compared to those not exposed to CV. The associations between CV and self-reported mental health and substance use were strongest for adolescents and attenuated across the adult age groups. CONCLUSION: Adolescence may represent a developmental period of heightened susceptibility to CV. Developing and evaluating targeted preventive interventions for this age group is warranted.

Awareness of, interest in, and willingness to pay for HIV pre-exposure prophylaxis among Canadian gay, bisexual, and other men who have sex with men

Abstract: Pre-exposure prophylaxis (PrEP) is a highly effective, HIV prevention strategy increasingly being accessed by gay, bisexual, and other men who have sex with men (GBMSM). GBMSM face structural and individual-level barriers accessing PrEP, including awareness and cost. This paper assesses socio-demographic factors associated with awareness, interest, and willingness to pay for PrEP in a sample of Canadian GBMSM. Data were derived from the 2015 Sex Now survey, a cross-sectional, online survey of GBMSM. Respondents were recruited through social media, sex-seeking “apps,” and by word of mouth. We used univariable and multivariable logistic regression models to estimate associations between socio-demographic factors and three primary outcomes. Our sample consisted of 7176 HIV-negative Canadian GBMSM. Of respondents, 54.7% were aware of PrEP, 47.4% were interested in PrEP, and 27.9% of PrEP-interested respondents reported they would pay for PrEP out-of-pocket. Awareness and interest varied between provinces, while GBMSM outside urban areas were less likely to be PrEP aware. Bisexual-identified men, and men over 50, were less likely to be aware and interested in PrEP in multivariable models. Only annual income and educational attainment were associated with willingness to pay for PrEP. This study identifies important disparities in awareness, interest, and willingness to pay for PrEP. Future interventions and educational efforts should target non-gay-identified and older GBMSM, as well as GBMSM outside urban areas. PrEP implementation may risk further perpetuating existing health inequities based on socio-economic status if PrEP continues to be accessed primarily through private insurance or paid for out-of-pocket.

Are young Canadians supportive of proposed nutrition policies and regulations? An overview of policy support and the impact of socio-demographic factors on public opinion.

Abstract: Many countries, including Canada, are considering nutrition policies that seek to improve dietary behaviour and related health outcomes. The current study examined support for policy measures among youth and young adults in Canada. Participants aged 16–30 years were recruited for online surveys using in-person intercept sampling in five Canadian cities as part of the Canada Food Study conducted in October–December, 2016 (n = 2729). Items included support for 21 specific policies in seven key areas: menu labelling, food package symbols and warnings, school policies, taxation and subsidies, zoning restrictions, marketing bans, and food formulation. Linear regression models examined support by age, sex, city, race/ethnicity, parental status, body mass index (BMI), and health literacy. Very high levels of support were observed for menu labelling in restaurants and schools, as well as food package symbols and warnings. Taxation, zoning restrictions (e.g., fast food and convenience stores near schools), and bans on marketing to children received relatively lower levels of support. In general, policy support increased with age for all 21 policies (p < 0.01) and greater health literacy for 4 policies (p < 0.05). Males were less supportive than females for 5 policies (p < 0.01). There were significant differences in support for specific race/ethnicity groups for 4 policies (p < 0.05). Support for menu labelling policies increased with BMI (p < 0.05). Overall, youth and young adults in Canada reported high levels of support for menu labelling, food package symbols/warnings, and school policies. Levels of support were generally consistent across socio-demographic subgroups, with some exceptions.

Cancer incidence among First Nations adults in Canada: follow-up of the 1991 Census Mortality Cohort (1992-2009)

Abstract: Estimate site-specific cancer incidence rates for a wide range of cancers in First Nations adults in Canada, and compare these with rates in non-Aboriginal adults. Responses from persons aged 25 and older to the 1991 Long Form Census were linked to national mortality and cancer databases. First Nations- and non-Aboriginal-specific incidence rates were age-standardized to the world standard population. The sex- and site-specific relative risks (RR) of cancer in First Nations compared to those in non-Aboriginal adults were estimated with Poisson regression. Results were stratified by residence on-reserve (all cancers combined) and region of Canada (four most common cancer sites). Compared to non-Aboriginal adults, First Nations had higher incidence of colon and rectum, kidney, cervix, and liver cancers and lower incidence of prostate, breast, bladder, uterus, ovary, and brain cancers, as well as non-Hodgkin lymphoma, leukemia, and melanoma. First Nations women additionally had higher incidence of stomach, gallbladder, and laryngeal cancers and lower incidence of thyroid cancers compared to non-Aboriginal women. The higher relative incidence of stomach and gallbladder cancers was observed only among First Nations adults who reported living on-reserve. Incidence of lung cancer was similar for First Nations and non-Aboriginal adults nationally, though variation by region of Canada was observed. First Nations people in Canada have disproportionately high rates of certain cancers, providing evidence to support public health policy and programming. More research is needed to identify factors contributing to the significantly lower incidence observed for various cancer types. Novel methods for studying disparities in cancer incidence among First Nations people are required to support ongoing cancer control planning and advocacy.

Trends in the awareness, acceptability, and usage of HIV pre-exposure prophylaxis among at-risk men who have sex with men in Toronto.

Abstract: Pre-exposure prophylaxis (PrEP) with daily oral tenofovir/emtricitabine dramatically reduces HIV risk in men who have sex with men (MSM). However, uptake is slow worldwide. We administered anonymous cross-sectional questionnaires to MSM presenting for anonymous HIV testing at a Toronto sexual health clinic at four successive time points during the period 2013–2016. We assessed trends in PrEP awareness, acceptability, and use over time using the Cochran-Armitage Trend Test, and identified barriers to using PrEP by constructing “PrEP cascades” using 2016 data. We assumed that to use PrEP, MSM must (a) be at risk for HIV, (b) be at objectively high risk (HIRI-MSM score ≥ 10), (c) perceive themselves to be at medium-to-high risk, (d) be aware of PrEP, (e) be willing to use PrEP, (f) have a family doctor, (g) be comfortable discussing sexual health with that doctor, and (h) have drug coverage/be willing to pay out of pocket. MSM participants were mostly white (54–59.5%), with median age 31 years (IQR = 26–38). PrEP awareness and use increased significantly over time (both p < 0.0001), reaching 91.3% and 5.0%, respectively, in the most recent wave. Willingness to use PrEP rose to 56.5%, but this increase did not reach statistical significance (p = 0.06). The full cascade, ABCDEFGH, suggested few could readily use PrEP under current conditions (11/400 = 2.8%). The largest barriers, in descending order, were low self-perceived HIV risk, unwillingness to use PrEP, and access to PrEP providers. To maximize its potential public health benefits, PrEP scale-up strategies must address self-perceived HIV risk and increase access to PrEP providers.

Beyond bare bones: critical, theoretically engaged qualitative research in public health.

Abstract: While qualitative inquiry has been a part of the Canadian Journal of Public Health (CJPH) for many years, CJPH does not yet have the reputation as a home for qualitative research that has a critical focus and that is cqqqonversant with contemporary developments in social theory and qualitative methodology. This paper describes efforts to establish CJPH as a welcoming home for critical, theoretically engaged qualitative research in public health. The paper introduces the Special Section that heralds the forward vision for qualitative research at CJPH. We specify what we mean by critical, theoretically engaged qualitative research and make the case for its significance for public health research and practice. We describe changes made in how qualitative manuscript submissions are handled at CJPH and highlight the contribution to public health scholarship made by the articles that comprise the Special Section. We issue an invitation to the public health community to support and participate in our vision to enhance critical, theoretically informed qualitative research in public health.

The elusive goal of social integration: A critical examination of the socio-economic and psychosocial consequences experienced by homeless young people who obtain housing

Abstract: The objective of this study was to provide an insider perspective on the experiences of nine formerly homeless young people as they transitioned into independent (market rent) housing and attempted to achieve meaningful social integration. The study was conducted in Toronto, Canada, and guided by the conceptual framework developed for the World Health Organization by the Commission on Social Determinants of Health. A critical ethnographic methodology was used. Over the course of 10 months, the lead author met every other week with nine formerly homeless young people who had moved into their own homes within 30 days prior to study recruitment. Unaffordable housing, limited education, inadequate employment opportunities, poverty-level income, and limited social capital made it remarkably challenging for the young people to move forward. As the study progressed, the participants’ ability to formulate long-range plans was impeded as they were forced to focus on day-to-day existence. Over time, living in a perpetual state of poverty led to feelings of “outsiderness,” viewing life as a game of chance, and isolation. Rather than a secure, linear path from the streets to the mainstream, study participants were forced to take a precarious path full of structural gaps that left them stuck, spinning, and exhausted by the day-to-day struggle to meet basic needs. Despite their remarkable agency, it was almost impossible for the participants to achieve meaningful social integration given the structural inequities inherent in society. These observations have implications for practice, policy, and research.

Clinical and functional characteristics of young adults living in single room occupancy housing: preliminary findings from a 10-year longitudinal study

Abstract: Young adults living in single room occupancy (SRO) hotels, a form of low-income housing, are known to have complex health and substance problems compared to their peers in the general population. The objective of this study is to comprehensively describe the mental, physical, and social health profile of young adults living in SROs. This study reports baseline data from young adults aged 18–29 years, as part of a prospective cohort study of adults living in SROs in Vancouver, British Columbia, Canada. Baseline and follow-up data were collected from 101 young adults (median follow-up period 1.9 years [IQR 1.0–3.1]). The comprehensive assessment included laboratory tests, neuroimaging, and clinician- and patient-reported measures of mental, physical, and social health and functioning. Three youth died during the preliminary follow-up period, translating into a higher than average mortality rate (18.6, 95% CI 6.0, 57.2) compared to age- and sex-matched Canadians. High prevalence of interactions with the health, social, and justice systems was reported. Participants were living with median two co-occurring illnesses, including mental, neurological, and infectious diseases. Greater number of multimorbid illnesses was associated with poorer real-world functioning (ρ = − 0.373, p < 0.001). All participants reported lifetime alcohol and cannabis use, with pervasive use of stimulants and opioids. This study reports high mortality rates, multimorbid illnesses, poor functioning, poverty, and ongoing unmet mental health needs among young adults living in SROs. Frequent interactions with the health, social, and justice systems suggest important points of intervention to improve health and functional trajectories of this vulnerable population.

Interprovincial variation in pre-pregnancy body mass index and gestational weight gain and their impact on neonatal birth weight with respect to small and large for gestational age

Abstract: To explore provincial variation in both excess and inadequate pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) and their impact on small- and large-for-gestational-age (SGA, LGA) infants. Four provinces with a perinatal database capturing the required exposures participated: British Columbia (BC), Ontario (ON), Nova Scotia (NS), and Newfoundland and Labrador (NL). In multiple, concurrent retrospective studies, we included women ≥ 19 years, who gave birth from 22+0 to 42+6 weeks’ gestation, to a live singleton from April 2013–March 2014. From adjusted odds ratios, we calculated population attributable fractions (PAF) of SGA and LGA for BMI and GWG. The proportion of overweight and obese women increased from western to eastern Canada. In BC, ON, NS, and NL, the proportions of women who were overweight were 21.1%, 24.0%, 23.7%, and 25.4%, while obesity proportions were 14.2%, 18.1%, 24.2%, and 29.8%, respectively. Excess GWG affected 53.9%, 49.9%, 57.6%, and 65.6% of women, respectively. Excess GWG contributed to 29.5–42.5% of LGA, compared with the PAFs for overweight (6.8–12.0%) and obesity (13.2–20.6%). Inadequate GWG’s contribution to SGA (4.8–12.3%) was higher than underweight BMI’s (2.9–6.2%). In this interprovincial study, high and increasing proportions of women from west to east had excess pre-pregnancy BMI, and between half to two thirds had excess GWG. The contributions of GWG outside of recommendations to SGA and LGA were greater than that of low or high BMI. GWG is a potentially modifiable determinant of SGA and LGA across Canada.

Bullying victimization and illicit drug use among students in Grades 7 to 12 in Manitoba, Canada: a cross-sectional analysis

Abstract: There is inconsistent evidence examining the relationship between bullying victimization and illicit drug use, with most studies only examining the association between bullying victimization and marijuana use. The current study aims to (1) determine the relationship between bullying victimization and six types of illicit drug use among boys and girls in grades 7 to 12 and (2) examine gender and grade differences in the relationships between bullying victimization and drug use. Data were drawn from the Manitoba Youth Health Survey (N = 64,174) collected in the 2012–2013 school year among students in grades 7 to 12 from Manitoba, Canada. Logistic regression models were used to analyze the relationships between nine different types of bullying victimization and marijuana, cocaine, methamphetamines, ecstasy, hallucinogens, and prescription/over-the-counter drugs used to get high. All analyses were stratified by gender and grade. Bullying victimization was associated with increased odds of all types of drug use among boys and girls in grades 7 to 12. A dose-response relationship was noted with more frequent bullying victimization corresponding to greater odds of drug use. Grade and gender differences were found for some drug use types. There are strong relationships between bullying victimization and illicit drug use among boys and girls in grades 7 to 12, indicating that reductions in bullying victimization may result in reductions in illicit drug use. Grade and gender differences may signify the need for early and gender-specific bullying prevention and intervention strategies.

Comparing individual and area-based income measures: impact on analysis of inequality in smoking, obesity, and diabetes rates in Canadians 2003–2013

Abstract: The aims of this study were to examine (1) the concordance between income measured at the individual and area-based level and (2) the impact of using each measure of income on inequality estimates for three health indicators—the prevalence, respectively, of diabetes, smoking, and obesity. Data for the health indicators and individual income among adults came from six cycles of the Canadian Community Health Survey (cycles 2003 through 2013). Area-based income was obtained by linking respondents’ residential postal codes to neighbourhood income quintiles derived from the 2006 Canadian census. Relative and absolute inequality between the lowest and highest income quintiles for each measure was assessed using rate ratios and rate differences, respectively. Concordance between the two income measures was poor in the overall sample (weighted Kappa estimates ranged from 0.19 to 0.21 for all years), and for the subset of participants reporting diabetes, smoking, or obesity. Despite the poor concordance, both individual and area-based income measures identified generally comparable levels of relative and absolute inequality in the rates of diabetes, smoking, and obesity over the 10-year study period. The results of this study show that individual and area-based income measures categorize Canadians differently according to income quintile, yet both measures reveal striking income-related inequalities in rates of diabetes and smoking, and obesity among women. This suggests that either individual or area-level measures can be used to monitor income-related health inequalities in Canada; however, whenever possible, it is informative to consider both measures since they likely represent distinct social constructs.

Child maltreatment and adult multimorbidity: results from the Canadian Community Health Survey

Abstract: This study investigated associations between three types of child maltreatment (exposure to intimate partner violence, sexual, and physical abuse) and multimorbidity (chronic physical conditions, pain conditions, and mental disorders) in adults. Multinomial logistic regression was used to analyze weighted data from the 2012 Canadian Community Health Survey (CCHS - MH 2012), a representative population sample (N = 23,846) of respondents ages 18+. All three subtypes of child maltreatment independently predicted increased odds of experiencing multimorbidity as an adult, while adjusting for covariates (adjusted odds ratios ranged from 1.34 (95% CI = 1.00, 1.80) to 4.87 (95% CI = 2.75, 8.63)). A dose-response relationship between the number of child maltreatment subtypes and risk for multimorbidity was also observed (adjusted odds ratios ranged from 1.38 (95% CI = 1.11, 1.73) to 10.96 (95% CI = 6.12, 19.64)). The current results highlight the importance of considering a range of childhood adversities and suggest that public health approaches that aim to decrease the prevalence and severity of child maltreatment have the potential to ameliorate adult multimorbidities. Future research is encouraged to investigate these issues using longitudinal population-level data.

A missed opportunity? Cannabis legalization and reparations in Canada.

Abstract: As Canada moves towards the legalization of cannabis, the Cannabis Act itself remains void of any complementary social justice measures. Decades of criminalization for the possession, production, and sale of cannabis will remain unscathed under this ostensibly new approach, leaving intact laws that have disproportionately and prejudicially impacted Indigenous people and people of colour. This includes the overpolicing and criminalization of these communities, furthering criminal justice disparities, and the lack of meaningful initiatives to aid communities of colour and Indigenous communities in participating in the legal cannabis industry. Despite the continuing impacts, the Government of Canada has made no commitment to tandem initiatives that address the issues of reparation for those who have been most heavily targeted under cannabis prohibition.

Disability and workplace harassment and discrimination among Canadian federal public service employees.

Abstract: Policy and legislation that prohibits workplace harassment and discrimination, including that which is disability related, has been in place in Canada for many years. The study objective was to examine associations between disability and workplace harassment and discrimination in the current Canadian context, as well as the intersection of disability with age, gender, and ethnicity. Cross-sectional data from the 2014 Canadian Public Service Employee Survey was analyzed (n = 175,742) using logistic regression to investigate the relationship between self-reported disability and workplace harassment and discrimination in the last 2 years. Age, gender, and ethnicity were included as potential confounders and effect modifiers. Additive and multiplicative effect modifications were examined using linear binomial and logistic regression, respectively. Overall, 18 and 8% of the sample of Canadian public service employees reported workplace harassment and discrimination, respectively. The prevalence was higher for workers with disability (37 and 26%). Disability was significantly associated with an increased odds of harassment (odds ratio (OR) = 2.80; 95% confidence interval (CI), 2.68–2.92) and discrimination (OR = 4.97; 95% CI, 4.72–5.23) in models adjusted for confounders. Significant positive additive effect modification was observed for (1) age in the harassment and discrimination models and (2) ethnicity in the discrimination model. Findings from a 2014 census of the Canadian federal public service suggest that additional efforts are needed to address workplace harassment and discrimination beyond those already in place. Consideration should be given to workers with disability, as well as the intersectional impacts for older workers, visible minorities, and Aboriginal peoples.

The Montreal heat response plan: evaluation of its implementation towards healthcare professionals and vulnerable populations.

Abstract: Since 2004, the Montreal heat response plan (MHRP) has been developed and implemented on the Island of Montreal to reduce heat-related health effects in the general population. In this paper, we aimed to assess the barriers and facilitators to implementation of the MHRP and evaluate the awareness of key elements of the plan by healthcare professionals and individuals from vulnerable populations. Data were gathered from monitoring reports and a questionnaire administered to managers of healthcare institutions and healthcare workers in Montreal-area health and social services institutions. Individual interviews and focus groups with healthcare workers and with individuals with schizophrenia or suffering from drug or alcohol dependencies were performed. Data were categorized according to predefined subthemes. Coding matrices were then used to determine the most frequently occurring elements in the subthemes. Our results indicate that actions are progressively implemented each year in the healthcare network. Intensification of surveillance for signs of heat-related illness is the most frequently reported measure. Identification and prioritization of clientele and homecare patients are identified as a challenge, as is ensuring the availability of sufficient personnel during a heat wave. Analysis of practice and awareness in healthcare professionals reveals that preventive measures are known and applied by the personnel. Individuals from vulnerable population groups were not uniformly aware of preventive measures, and consequently, variability was observed in their application. The framework proposed in this study revealed valuable information that can be useful to improve plans aimed at reducing heat-related health effects in the population.

Geographic disparities in accessing community pharmacies among vulnerable populations in the Greater Toronto Area

Abstract: Geographic accessibility to community pharmacies (CPs) plays an increasingly important role for the well-being of a community. This study examines the geographic distribution of CPs within the Greater Toronto Area (GTA) relative to the residential patterns of vulnerable populations, including older adults (65+ years), infants and children (0–9 years), and low-income households. The study develops a geographic accessibility index at a dissemination area (DA) level by employing the enhanced two-step floating catchment area (E2SFCA) method to measure geographic accessibility to pharmacies. A vulnerability index is also developed to assess and visualize the residential patterns of vulnerable groups. A combined vulnerability-accessibility index is then constructed to identify low-access areas associated with high levels of socio-economic vulnerability. A range of geo-referenced datasets are analyzed within a geographical information system. The study reveals geographical disparities in accessing pharmacies between urban and suburban areas and across different neighbourhoods, while accounting for population density and distance decay. About 19% of the population (or 15% of DAs) are under-serviced, with very poor geographic access to CPs (1.7 CPs per 10,000 persons), compared to 29.6% of the DAs that are well-/over-serviced, with an average score of 2.8 CPs per 10,000 persons. The spatial-quantitative analysis at a small geography (DA) allows for improved accuracy for identifying specific neighbourhoods that are in need of greater access to pharmacies by vulnerable residents and areas that have an excessive supply of pharmacies. It provides implications for addressing barriers to accessing pharmacies among high-needs groups, including the rapidly growing older adult population in the GTA.

And if there were another way out? Questioning the prevalent radicalization models.

Abstract: Violent radicalization is increasingly conceptualized as a public health issue, associated with psychological distress, a sharp increase in discrimination and profiling, and an increase in hate crime and some types of terrorist acts.This brief paper addresses the limitations of the current conceptual models of violent radicalization. Beyond understanding the path leading from radicalization of opinion to violent radicalization, it proposes to consider the non-violent outcomes of radicalization of opinions in the current social context and to study these outcomes in multiple settings for both minorities and majorities. Moving beyond the implicit linearity of current models and promoting a systemic vision would help to decrease the actual profiling of targeted communities and support the design of community-based prevention programs structured on these alternative outcomes, and in particular on the emergence of social solidarities in groups expressing discontent with the status quo.

Determinants of non-vaccination against seasonal influenza in Canadian adults: findings from the 2015-2016 Influenza Immunization Coverage Survey.

Abstract: The study objectives were to (1) identify determinants of non-vaccination against seasonal influenza in Canadian adults and (2) examine self-reported reasons for non-vaccination. The data source was the 2015–2016 Influenza Immunization Coverage Survey, a national telephone survey of Canadian adults. Participants (n = 1950) were divided into three groups: adults aged 18–64 years with (n = 408) and without (n = 1028) chronic medical conditions (CMC) and adults ≥ 65 years (n = 514). Logistic regression was used to measure associations between sociodemographic factors and non-vaccination for the 2015–2016 influenza season. Weighted proportions were calculated to determine the main self-reported reasons for not receiving the influenza vaccine. Younger age was found to be associated with non-vaccination across all groups. In adults ≥ 65 years, elementary- or secondary- vs. university-level education (aOR 1.87, 95% CI 1.14-3.06) was also significantly associated with non-vaccination. Significant variation in vaccine uptake was found for several sociodemographic factors in adults aged 18–64 without CMC. Low perceived susceptibility or severity of influenza and lack of belief in the vaccine’s effectiveness were the most commonly reported reasons for not receiving the vaccine. In general, our results were consistent with findings from other Canadian and American studies on seasonal influenza vaccine uptake. Belief that the influenza vaccine is not needed was common, even among those at increased risk of influenza-related complications. Additional research is needed to better understand how sociodemographic factors such as income and education may influence uptake and to raise awareness of potential complications from influenza infection in high-risk adults.

Carbon pricing: a win-win environmental and public health policy.

Abstract: Carbon pricing is an important tool for mitigating climate change. Carbon pricing can have significant health co-benefits. Air pollution from fossil fuels leads to detrimental health effects, including premature mortality, heart attacks, hospitalization from cardiorespiratory conditions, stroke, asthma exacerbations, and absenteeism from school and work, and may also be linked to autism spectrum disorder and Alzheimer’s disease. Reduction in fossil fuel combustion through a carbon price can lead to improvements in all these areas of health. It can also improve health by encouraging active transportation choices and improving ecosystems. Furthermore, it can promote health equity in society and improve overall societal health where the revenue from carbon pricing is used as a progressive redistribution mechanism for low-income households. Hence, carbon pricing is a win-win environmental and public health policy and an important step toward achieving Canada’s emission target by 2030. However, carbon pricing has several potential pitfalls which need to be considered in the design and implementation of any such policy. As Canada moves ahead with mandatory carbon pricing this fall, it is important to monitor its impact, evaluate it objectively, and modify and complement as necessary with policies and regulations.

The effect of socio-demographic factors on mental health and addiction high-cost use: a retrospective, population-based study in Saskatchewan.

Abstract: A small proportion of the population accounts for the majority of healthcare costs. Mental health and addiction (MHA) patients are consistently high-cost. We aimed to delineate factors amenable to public health action that may reduce high-cost use among a cohort of MHA clients in Saskatoon, Saskatchewan. We conducted a population-based retrospective cohort study. Administrative health data from fiscal years (FY) 2009–2015, linked at the individual level, were analyzed (n = 129,932). The outcome of interest was ≥ 90th percentile of costs for each year under study (‘persistent high-cost use’). Descriptive analyses were followed by logistic regression modelling; the latter excluded long-term care residents. The average healthcare cost among study cohort members in FY 2009 was ~ $2300; for high-cost users it was ~ $19,000. Individuals with unstable housing and hospitalization(s) had increased risk of persistent high-cost use; both of these effects were more pronounced as comorbidities increased. Patients with schizophrenia, particularly those under 50 years old, had increased probability of persistent high-cost use. The probability of persistent high-cost use decreased with good connection to a primary care provider; this effect was more pronounced as the number of mental health conditions increased. Despite constituting only 5% of the study cohort, persistent high-cost MHA clients (n = 6455) accounted for ~ 35% of total costs. Efforts to reduce high-cost use should focus on reduction of multimorbidity, connection to a primary care provider (particularly for those with more than one MHA), young patients with schizophrenia, and adequately addressing housing stability.

Our health counts: population-based measures of urban Inuit health determinants, health status, and health care access

Abstract: Health determinants and outcomes are not well described for the growing population of Inuit living in southern urban areas of Canada despite known and striking health disparities for Inuit living in the north. The objective of this study was to work in partnership with Tungasuvvingat Inuit (TI) to develop population prevalence estimates for key indicators of health, including health determinants, health status outcomes, and health services access for Inuit in Ottawa, Canada. We employed community-based respondent driven sampling (RDS) and a comprehensive health assessment survey to collect primary data regarding health determinants, status, and service access. We then linked with datasets held by the Institute for Clinical Evaluative Sciences (ICES), including hospitalization, emergency room, and health screening records. Adjusted population-based prevalence estimates and rates were calculated using custom RDS software. We recruited 341 Inuit adults living in Ottawa. The number of Inuit living, working or accessing health and social services in the City of Ottawa was estimated to be 3361 (95% CI 2309–4959). This population experiences high rates of poverty, unemployment, household crowding, and food insecurity. Prevalence of hypertension (25%; 95% CI 18.1–33.9), chronic obstructive pulmonary disease (6.7%; 95% CI 3.1–10.6), cancer (6.8%; 95% CI 2.7–11.9), and rates of emergency room access were elevated for Inuit in Ottawa compared to the general population. Access to health services was rated fair or poor by 43%. Multiple barriers to health care access were identified. Urban Inuit experience a heavy burden of adverse health determinants and poor health status outcomes. According to urban Inuit in Ottawa, health services available to Inuit at the time of the study were inadequate.
