Background. Rates of depression have been rising, as have rates of work stress. We tested the influence of work stress on diagnosed depression and anxiety in young working adults. Method. Participants were enrolled in the Dunedin study, a 1972-1973 longitudinal birth cohort assessed most recently in 2004-2005, at age 32 (n=972, 96% of 1015 cohort members still alive). Work stress (psychological job demands, work decision latitude, low work social support, physical work demands) was ascertained by interview. Major depressive disorder (MDD) and generalized anxiety disorder (GAD) were ascertained using the Diagnostic Interview Schedule (DIS) and diagnosed according to DSM-IV criteria. Results. Participants exposed to high psychological job demands (excessive workload, extreme time pressures) had a twofold risk of MDD or GAD compared to those with low job demands. Relative risks (RRs) adjusting for all work characteristics were: 1·90 [95% confidence interval (CI) 1·22-2·98] in women, and 2·00 (95 % CI 1·13-3·56) in men. Analyses ruled out the possibility that the association between work stress and disorder resulted from study members' socio-economic position, a personality tendency to report negatively, or a history of psychiatric disorder prior to labour-market entry. Prospective longitudinal analyses showed that high-demand jobs were associated with the onset of new depression and anxiety disorder in individuals without any pre-job history of diagnosis or treatment for either disorder. Conclusions. Work stress appears to precipitate diagnosable depression and anxiety in previously healthy young workers. Helping workers cope with work stress or reducing work stress levels could prevent the occurrence of clinically significant depression and anxiety.

Work stress precipitates depression and anxiety in young, working women and men. Commentary

Background The role of walking, as compared with vigorous exercise, in the prevention of coronary heart disease remains controversial, and data for women on this topic are sparse. Methods We prospectively examined the associations between the score for total physical activity, walking, and vigorous exercise and the incidence of coronary events among 72,488 female nurses who were 40 to 65 years old in 1986. Participants were free of diagnosed cardiovascular disease or cancer at the time of entry and completed serial detailed questionnaires about physical activity. During eight years of follow-up, we documented 645 incident coronary events (nonfatal myocardial infarction or death from coronary disease). Results There was a strong, graded inverse association between physical activity and the risk of coronary events. As compared with women in the lowest quintile group for energy expenditure (expressed as the metabolic-equivalent [MET] score), women in increasing quintile groups had age-adjusted relative risks of 0.77, 0.65, 0.54, and 0.46 for coronary events (P for trend or =6 MET) was associated with similar risk reductions (30 to 40 percent). Sedentary women who became active in middle adulthood or later had a lower risk of coronary events than their counterparts who remained sedentary. Conclusions These prospective data indicate that brisk walking and vigorous exercise are associated with substantial and similar reductions in the incidence of coronary events among women.

A Prospective Study of Walking as Compared with Vigorous Exercise in the Prevention of Coronary Heart Disease in Women

Importance Studies have established the importance of physical activity and fitness, yet limited data exist on the associations between objective, real-world physical activity patterns, fitness, sleep, and cardiovascular health. Objectives To assess the feasibility of obtaining measures of physical activity, fitness, and sleep from smartphones and to gain insights into activity patterns associated with life satisfaction and self-reported disease. Design, Setting, and Participants The MyHeart Counts smartphone app was made available in March 2015, and prospective participants downloaded the free app between March and October 2015. In this smartphone-based study of cardiovascular health, participants recorded physical activity, filled out health questionnaires, and completed a 6-minute walk test. The app was available to download within the United States. Main Outcomes and Measures The feasibility of consent and data collection entirely on a smartphone, the use of machine learning to cluster participants, and the associations between activity patterns, life satisfaction, and self-reported disease. Results From the launch to the time of the data freeze for this study (March to October 2015), the number of individuals (self-selected) who consented to participate was 48 968, representing all 50 states and the District of Columbia. Their median age was 36 years (interquartile range, 27-50 years), and 82.2% (30 338 male, 6556 female, 10 other, and 3115 unknown) were male. In total, 40 017 (81.7% of those who consented) uploaded data. Among those who consented, 20 345 individuals (41.5%) completed 4 of the 7 days of motion data collection, and 4552 individuals (9.3%) completed all 7 days. Among those who consented, 40 017 (81.7%) filled out some portion of the questionnaires, and 4990 (10.2%) completed the 6-minute walk test, made available only at the end of 7 days. The Heart Age Questionnaire, also available after 7 days, required entering lipid values and age 40 to 79 years (among 17 245 individuals, 43.1% of participants). Consequently, 1334 (2.7%) of those who consented completed all fields needed to compute heart age and a 10-year risk score. Physical activity was detected for a mean (SD) of 14.5% (8.0%) of individuals’ total recorded time. Physical activity patterns were identified by cluster analysis. A pattern of lower overall activity but more frequent transitions between active and inactive states was associated with equivalent self-reported cardiovascular disease as a pattern of higher overall activity with fewer transitions. Individuals’ perception of their activity and risk bore little relation to sensor-estimated activity or calculated cardiovascular risk. Conclusions and Relevance A smartphone-based study of cardiovascular health is feasible, and improvements in participant diversity and engagement will maximize yield from consented participants. Large-scale, real-world assessment of physical activity, fitness, and sleep using mobile devices may be a useful addition to future population health studies.

Feasibility of Obtaining Measures of Lifestyle From a Smartphone App: The MyHeart Counts Cardiovascular Health Study.

The Asia-Pacific perspectibve: Redefining obesity and its treatmentの刊行をめぐって

BACKGROUND\nWe sought to examine the relationship between health-related quality of life (HRQL) and a first emergency rehospitalization and mortality in patients with heart failure (HF) having a wide variation in ventricular ejection fraction and functional status.\n\n\nMETHODS\nProspective study conducted with 394 patients admitted for HF-related emergencies at 4 Spanish hospitals. Baseline HRQL was measured with a generic questionnaire, the Medical Outcomes Study 36-item Short Form Survey (SF-36), and with an HF-specific instrument, the Minnesota Living With Heart Failure (MLWHF) questionnaire. Cox proportional hazards models were used to calculate hazard ratios (HRs) for hospitalization and death on the basis of HRQL scores.\n\n\nRESULTS\nDuring a median follow-up of approximately 6 months, 138 patients (35.0%) underwent a first emergency rehospitalization and 70 (17.8%) died. After adjustment for biomedical, psychosocial, and health care variables, the frequency of hospital readmission was higher in patients with worse scores on the SF-36 physical functioning (HR, 1.65; 95% confidence interval [CI], 1.11-2.44; P = .01), general health (HR, 1.73; 95% CI, 1.19-2.52; P = .003), and mental health (HR, 1.65; 95% CI, 1.10-2.47; P = .02) subscales. Results were similar for the mortality end point. For the MLWHF questionnaire, worse overall and worse physical and emotional summary scores were associated with higher mortality.\n\n\nCONCLUSIONS\nWorse HRQL is associated with hospital readmission and death in patients with HF. The magnitude of this association, for both physical and mental HRQL components, is comparable to that for other well-known predictors of hospital readmission and death, such as personal history of diabetes, previous hospitalizations, and treatment with angiotensin-converting enzyme inhibitors.

Health-Related Quality of Life as a Predictor of Hospital Readmission and Death Among Patients With Heart Failure

Evaluating the prevalence, awareness, and control of hypertension, diabetes, and dyslipidemia in Korea using the NHIS-NSC database: A cross-sectional analysis.

Patients with rheumatoid arthritis are at increased risk for cardiovascular disease. The prerequisites for reducing the risk of cardiovascular disease are adequate levels of knowledge and being aware of the risk. In this study, the levels of knowledge about cardiovascular disease among patients with rheumatoid arthritis and the perception were evaluated in relation to their actual 10-year risk of cardiovascular disease. This cross-sectional study of 200 patients with rheumatoid arthritis was conducted in a university-affiliated hospital in South Korea. The patients’ actual risk of cardiovascular disease was estimated using the Framingham Risk Score. The most common risk factor was physical inactivity, with 77% of the patients not engaging in regular exercise. The patients lacked knowledge about the effects of physical inactivity and anti-inflammatory medication on the development of cardiovascular disease. Misperceptions about the risk of cardiovascular disease were common, i.e., 19.5% of the patients underestimated their risk and 41% overestimated. Hypertension, diabetes, obesity, and smoking were the most prevalent among the patients who underestimated their risk, and these same patients had the lowest level of knowledge about cardiovascular disease. This study demonstrated the rheumatoid arthritis patients’ lack of knowledge about the effects of physical inactivity and anti-inflammatory medications on the development of cardiovascular disease, and their misperception of cardiovascular risk was common. As a preventive measure, educational programs about cardiovascular disease should be tailored specifically for patients with rheumatoid arthritis, and behavioral interventions, including routine exercise, should be made available at the time of diagnosis.

Cardiovascular Risk Factors and 10-year Risk for Coronary Heart Disease in Korean Women

Both the beneficial relationship between exercise and quality of life and the important role played by exercise self-efficacy in maintaining an exercise regimen among individuals with chronic heart failure are well known. However, most nursing interventions for Korean patients with chronic heart failure focus only on providing education related to risk factors and symptoms. Little information is available regarding the influence of physical functions, physical activity, and exercise self-efficacy on quality of life.
This study was conducted to examine the impact of physical functioning, physical activity, and exercise self-efficacy on quality of life among individuals with chronic heart failure.
This study used a cross-sectional descriptive design. Data were collected from 116 outpatients with chronic heart failure in Korea. Left ventricular ejection fraction and New York Heart Association classifications were chart reviewed. Information pertaining to levels of physical activity, exercise self-efficacy, and quality of life were collected using self-administered questionnaires. Data were analyzed using descriptive statistics, t tests, analyses of variance, correlations, and hierarchical multiple regressions.
About 60% of participants were physically inactive, and most showed relatively low exercise self-efficacy. The mean quality-of-life score was 80.09. The significant correlates for quality of life were poverty, functional status, physical inactivity, and exercise self-efficacy. Collectively, these four variables accounted for 50% of the observed total variance in quality of life.
Approaches that focus on enhancing exercise self-efficacy may improve patient-centered outcomes in those with chronic heart failure. In light of the low level of exercise self-efficacy reported and the demonstrated ability of this factor to predict quality of life, the development of effective strategies to enhance exercise self-efficacy offers a novel and effective approach to improving the quality of life of patients with chronic heart failure. Nurses should be proactive in advising patients with chronic heart failure to be more physically active and to enhance their self-confidence in diverse ways.

Physical Functioning, Physical Activity, Exercise Self-Efficacy, and Quality of Life Among Individuals With Chronic Heart Failure in Korea: A Cross-Sectional Descriptive Study

Aim
Self-perceived poor health is related to cardiovascular disease (CVD) risk perception, cardiovascular event, hospital readmission, and death from CVD. This study evaluated the associations between self-perceived health and actual CVD risk in South Koreans as well as the influence of sociodemographic and cardiovascular risk factors on self-perceived poor health.

Methods
This is a secondary data analysis of the 2010 Korea National Health and Nutrition Examination Survey. The sample was 4535 South Koreans aged 30–74 years without CVD. Self-perceived health status was compared with actual cardiovascular risk separately by sex using χ2-tests. Logistic regressions were used to identify potential sociodemographic and cardiovascular risk factors of self-perceived poor health.

Results
Self-perceived poor health was related to higher CVD risk but there were substantial gaps between them. Among cardiovascular risk factors, dyslipidemia, obesity, smoking, and a family history of CVD did not affect self-perceived health.

Conclusion
Gaps between perceived health and actual CVD risk should be closed to optimize cardiovascular health of South Koreans. Koreans need to increase risk perception to a level commensurate with their actual risk. Healthcare providers should try to provide individuals at increased CVD risk with better information more frequently, especially those who have favorable perceptions of their health but smoke or have elevated cholesterol levels and bodyweight.
