Community-based research in public health focuses on social, structural, and physical environmental inequities through active involvement of community members, organizational representatives, and researchers in all aspects of the research process. Partners contribute their expertise to enhance understanding of a given phenomenon and to integrate the knowledge gained with action to benefit the community involved. This review provides a synthesis of key principles of community-based research, examines its place within the context of different scientific paradigms, discusses rationales for its use, and explores major challenges and facilitating factors and their implications for conducting effective community-based research aimed at improving the public’s health.

Global physical activity levels: surveillance progress, pitfalls, and prospects

BULLYING AMONG SCHOOL-AGED youth is increasingly being recognized as an important problem affecting well-being and social functioning. While a certain amount of conflict and harassment is typical of youth peer relations, bullying presents a potentially more serious threat to healthy youth development. The definition of bullying is widely agreed on in literature on bullying.1–4 Bullying is a specific type of aggression in which (1) the behavior is intended to harm or disturb, (2) the behavior occurs repeatedly over time, and (3) there is an imbalance of power, with a more powerful person or group attacking a less powerful one. This asymmetry of power may be physical or psychological, and the aggressive behavior may be verbal (eg, name-calling, threats), physical (eg, hitting), or psychological (eg, rumors, shunning/exclusion).

The majority of research on bullying has been conducted in Europe and Australia. Considerable variability among countries in the prevalence of bullying has been reported. In an international survey of adolescent health-related behaviors, the percentage of students who reported being bullied at least once during the current term ranged from a low of 15% to 20% in some countries to a high of 70% in others.5,6 Of particular concern is frequent bullying, typically defined as bullying that occurs once a week or more. The prevalence of frequent bullying reported internationally ranges from a low of 1.9% among 1 Irish sample to a high of 19% in a Malta study.1,7–12

Bullying takes many forms, and findings about the types of bullying that occur are fairly similar across countries. A British study involving 23 schools found that direct verbal aggression was the most common form of bullying, occurring with similar frequency in both sexes.13 Direct physical aggression was more common among boys, while indirect forms were more common among girls. Similarly, in a study of several middle schools in Rome, the most common types of bullying reported by boys were threats, physical harm, rejection, and name-calling.14 The most common forms for girls were name-calling, teasing, rumors, rejection, and taking of personal belongings.

Research examining characteristics of youth involved in bullying has consistently found that both bullies and those bullied demonstrate poorer psychosocial functioning than their noninvolved peers. Youth who bully others tend to demonstrate higher levels of conduct problems and dislike of school, whereas youth who are bullied generally show higher levels of insecurity, anxiety, depression, loneliness, unhappiness, physical and mental symptoms, and low self-esteem.1–4,8,15–25 Males who are bullied also tend to be physically weaker than males in general.2 The few studies that have examined the characteristics of youth who both bully and are bullied found that these individuals exhibit the poorest psychosocial functioning overall.15,17,19,26

The current research provides a foundation for an understanding of the bullying problem. However, it is insufficient to guide intervention and policy development. Moreover, little is known specifically about bullying among US youth.6 In one county-wide middle school survey, 24.1% of youth reported bullying others at least once in the past semester26; it is not known whether this is characteristic of the rest of the nation.

The purpose of this study was to report the prevalence of bullying in a nationally representative sample of US youth in grades 6 through 10, along with information on differences in the prevalence of bullying by sex, grade, and race. In addition, the relationships among bullying, being bullied, and psychosocial adjustment are explored for 3 distinct groups: bullies only, those bullied only, and those who both bully and are bullied.

Bullying Behaviors Among US Youth: Prevalence and Association With Psychosocial Adjustment

As people get older, they may fall more often for a variety of reasons including problems with balance, poor vision, and dementia. Up to 30% may fall in a year. Although one in five falls may require medical attention, less than one in 10 results in a fracture.
This review looked at the healthcare literature to establish which fall prevention interventions are effective for older people living in the community, and included 159 randomised controlled trials with 79,193 participants.  
Group and home-based exercise programmes, usually containing some balance and strength training exercises, effectively reduced falls, as did Tai Chi. Overall, exercise programmes aimed at reducing falls appear to reduce fractures.
Multifactorial interventions assess an individual's risk of falling, and then carry out treatment or arrange referrals to reduce the identified risks. Overall, current evidence shows that this type of intervention reduces the number of falls in older people living in the community but not the number of people falling during follow-up. These are complex interventions, and their effectiveness may be dependent on factors yet to be determined.  
Interventions to improve home safety appear to be effective, especially in people at higher risk of falling and when carried out by occupational therapists. An anti-slip shoe device worn in icy conditions can also reduce falls.
Taking vitamin D supplements does not appear to reduce falls in most community-dwelling older people, but may do so in those who have lower vitamin D levels in the blood before treatment.  
Some medications increase the risk of falling. Three trials in this review failed to reduce the number of falls by reviewing and adjusting medications. A fourth trial involving family physicians and their patients in medication review was effective in reducing falls. Gradual withdrawal of a particular type of drug for improving sleep, reducing anxiety, and treating depression (psychotropic medication) has been shown to reduce falls.
Cataract surgery reduces falls in women having the operation on the first affected eye. Insertion of a pacemaker can reduce falls in people with frequent falls associated with carotid sinus hypersensitivity, a condition which causes sudden changes in heart rate and blood pressure.
In people with disabling foot pain, the addition of footwear assessment, customised insoles, and foot and ankle exercises to regular podiatry reduced the number of falls but not the number of people falling.
The evidence relating to the provision of educational materials alone for preventing falls is inconclusive.

Interventions for preventing falls in older people living in the community

Objectives: To examine the prevalence of bullying behaviours in schoolchildren and the association of bullying with psychological and psychosomatic health. Design: Cross sectional survey. Setting: Government and non-government schools in New South Wales, Australia. Participants: 3918 schoolchildren attending year 6 (mean age 11.88 years), year 8 (13.96), and year 10 (15.97) classes from 115 schools. Main outcome measures: Self reported bullying behaviours and psychological and psychosomatic symptoms. Results: Almost a quarter of students (23.7%) bullied other students, 12.7% were bullied, 21.5% were both bullied and bullied others on one or more occasions in the last term of school, and 42.4% were neither bullied nor bullied others. More boys than girls reported bullying others and being victims of bullying. Bullying behaviour was associated with increased psychosomatic symptoms Bullies tended to be unhappy with school; students who were bullied tended to like school and to feel alone. Students who both bullied and were bullied had the greatest number of psychological and psychosomatic symptoms. Conclusions: Being bullied seems to be widespread in schools in New South Wales and is associated with increased psychosomatic symptoms and poor mental health. Health practitioners evaluating students with common psychological and psychosomatic symptoms should consider bullying and the student9s school environment as potential causes. Key messages Bullying behaviour occurs in schools worldwide and is likely to be associated with poor health in schoolchildren Research into bullying has been mainly focused on victims but there are other categories of bullying that deserve attention At least three out of five students experienced or participated in bullying in schools in New South Wales, Australia The psychosocial and psychosomatic health of the students varied according to their bullying status

Bullying behaviour and psychosocial health among school students in New South Wales, Australia: cross sectional survey

Potentially, empowerment has much to offer health promotion. However, some caution needs to be exercised before the notion is wholeheartedly embraced as the major goal of health promotion. The lack of a clear theoretical underpinning, distortion of the concept by different users, measurement ambiguities, and structural barriers make 'empowerment' difficult to attain. To further discussion, th is paper proposes several assertions about the definition, components, process and outcome of 'empowerment', including the need for a distinction between psychological and community empowerment. These assertions and a model of community empowerment are offered in an attempt to clarify an important issue for health promotion.

Empowerment: the holy grail of health promotion?

Active travel, particularly walking and cycling, has been recommended because of the health benefits associated with increased physical activity. Use of public transport generally involves some walking to bus stops or train stations. This paper is a systematic review of how much time is spent in physical activity among adults using public transport. It also explores the potential effect on the population level of physical activity if inactive adults in NSW, Australia, increased their walking through increased use of public transport. Of 1,733 articles, 27 met the search criteria, and nine reported on absolute measures of physical activity associated with public transport. A further 18 papers reported on factors associated with physical activity as part of public transport use. A range of 8-33 additional minutes of walking was identified from this systematic search as being attributable to public transport use. Using "bootstrapping" statistical modelling, if 20% of all inactive adults increased their walking by only 16 minutes a day for five days a week, we predict there would be a substantial 6.97% increase in the proportion of the adult population considered "sufficiently active". More minutes walked per day, or a greater uptake of public transport by inactive adults would likely lead to significantly greater increases in the adult population considered sufficiently active.

Physical Activity Associated with Public Transport Use—A Review and Modelling of Potential Benefits

OBJECTIVES: To determine the effectiveness of a 16-week community-based tai chi program in reducing falls and improving balance in people aged 60 and older. DESIGN: Randomized, controlled trial with waiting list control group. SETTING: Community in Sydney, Australia. PARTICIPANTS: Seven hundred two relatively healthy community-dwelling people aged 60 and older (mean age 69). INTERVENTION: Sixteen-week program of communitybased tai chi classes of 1 hour duration per week. MEASUREMENTS: Falls during 16 and 24 weeks of follow-up were assessed using a calendar method. Balance was measured at baseline and 16-week follow-up using six balance tests. RESULTS: Falls were less frequent in the tai chi group than in the control group. Using Cox regression and time to first fall, the hazard ratio after 16 weeks was 0.72 (95% confidence interval (CI) 50.51‐1.01, P 5.06), and after 24 weeks it was 0.67 (95% CI 50.49‐0.93, P 5.02). There was no difference in the percentage of participants who had one or more falls. There were statistically significant differences in changes in balance favoring the tai chi group on five of six balance tests. CONCLUSION: Participation in once per week tai chi classes for 16 weeks can prevent falls in relatively healthy community-dwelling older people. J Am Geriatr Soc 55:1185–1191, 2007.

Parents play a critical role in developing and shaping their children's physical activity (PA) and sedentary behaviours, particularly in the early years of life. The aim of this systematic review is to identify current literature investigating associations of parental influences with both PA and screen time in young children. This systematic review was conducted in November 2013 using 6 electronic databases covering research literature from January 1998 to November 2013. Thirty articles that met inclusion criteria were identified. These studies covered five important aspects of parenting: (1) parenting practices; (2) parents' role modelling; (3) parental perceptions of children's PA and screen viewing behaviours; (4) parental self-efficacy; and (5) general parenting style. Findings suggest that parents' encouragement and support can increase children's PA, and reducing parents' own screen time can lead to decreased child screen time. Improving parenting practices, parental self-efficacy or changing parenting style may also be promising approaches to increasing PA time and decreasing screen time of young children.
