Physical activity and exercise in the maintenance of the adult skeleton and the prevention of osteoporotic fractures

In the prevention of osteoporosis and osteoporoticrelated fractures, strategies aimed at maximizing peak bone mass during childhood and adolescence; maintaining or attenuating bone loss during the adult years; and increasing or preserving muscle mass, strength, power, and function are all considered critical. To this end, physical activity and exercise are recognized as important modifiable lifestyle variables that can strengthen the skeleton and muscles and reduce the risk of falls and subsequent fracture, as well as enhance quality of life... 

Outcome measurement of community based mental health services in Western Australia: literature and concept summary

The paper aims to provide a brief overview of key ideas related to outcome measurement relevant to community based mental health services and their consumers in WA. Due to the breadth of scope of the paper, it is not an extensive or rigorous literature review but provides a scan of the literature that could shape a more thorough literature review in any of the content areas. The paper has been written with the aim of informing the sector of key ideas, issues, concepts and approaches.

The effect of obesity prevention interventions according to socioeconomic position: a systematic review

Obesity prevention is a major public health priority. It is important that all groups benefit from measures to prevent obesity, but we know little about the differential effectiveness of such interventions within particular population subgroups. This review aimed to identify interventions for obesity prevention that evaluated a change in adiposity according to socioeconomic position (SEP) and to determine the effectiveness of these interventions across different socioeconomic groups. A systematic search of published and grey literature was conducted. Studies that described an obesity prevention intervention and reported anthropometric outcomes according to a measure of SEP were included. Evidence was synthesized using narrative analysis. A total of 14 studies were analysed, representing a range of study designs and settings. All studies were from developed countries, with eight conducted among children. Three studies were shown to have no effect on anthropometric outcomes and were not further analysed. Interventions shown to be ineffective in lower SEP participants were primarily based on information provision directed at individual behaviour change. Studies that were shown to be effective in lower SEP participants primarily included community-based strategies or policies aimed at structural changes to the environment. Interventions targeting individual-level behaviour change may be less successful in lower SEP populations. It is essential that our efforts to prevent obesity do not leave behind the most disadvantaged members of society.

Developing programs for African families, by African families: engaging African migrant families in Melbourne in health promotion interventions

Obesity is an emerging problem for African migrants in Australia, but few prevention programs incorporate their cultural beliefs and values. This study reports on the application of community capacity-building and empowerment principles in 4 workshops with Sudanese families in Australia. Workshop participants prioritized health behaviors, skill and knowledge gaps, and environments for change to identify culturally centered approaches to health promotion. The workshops highlighted a need for culturally and age-appropriate interventions that build whole-of-family skills and knowledge around the positive effects of physical activity and nutrition to improve health within communities while reducing intergenerational and gender role family conflicts.

Community-based childhood obesity prevention

This thesis found that targeting obesogenic behaviours through community based interventions leads to reduced childhood overweight/obesity. Obesogenic behaviours included sugary drinks and high fat food consumption, low physical activity and high levels of sedentariness. When packaged they are more successful in preventing childhood obesity than they are when targeted singly.

Managing the risks from new and emerging infectious disease: the 'one health' paradigm

The global risk from new and emerging infectious diseases continues to grow with recognition that, for the most part, the pathogens involved emerge from animals to infect humans. Recognizing the complexity of these interactions and the need for a strong interdisciplinary approach to effectively manage these risks, new partnerships are being forged under the general umbrella of 'one health'. Involving human health, animal health, and environmental health exponents, solutions are sought for how to prevent as well as respond to the threats. But is this approach working? Whilst a number of key meetings continue to be held under the One Health umbrella, are we really seeing measureable progress in risk prevention and mitigation? Focusing research on the drivers for emergence, on modeling the risks, on improved diagnostics, and on targeted vaccines could considerably enhance our ability to prevent and respond. Ensuring the uptake and applications of new diagnostics and vaccines will be the key to prevention and response, but achieving this will require policies that drive further the One Health collaborations. Such policies should ensure that scant available resources are targeted toward the identified outcomes through research delivery and uptake, and that we genuinely work as "one world" in tackling the very real risks we face

Process evaluation of a community-based intervention program: Healthy Youth Healthy Communities, an adolescent obesity prevention project in Fiji

Nearly one-half of the adult population in Fiji between the ages of 15–64 years is either overweight or obese; and rates amongst school children have, on average, doubled during the last decade. There is an urgent need to scale up the promotion of healthy behaviors and environments using a multi-sectoral approach. The Healthy Youth Healthy Community (HYHC) project in Fiji used a settings approach in secondary schools and faith-based organizations to increase the capacity of the whole community, including churches, mosques and temples, to promote healthy eating and regular physical activity, and to prevent unhealthy weight gain in adolescents aged 13–18 years. The team consisted of a study manager, project coordinator and four research assistants (RAs) committed to planning, designing and facilitating the implementation of intervention programs in collaboration with other stakeholders, such as the wider school communities, government and non-governmental organizations and business partners. Process data were collected on all intervention activities and analyzed by dose, frequency and reach for each specific strategy. The Fiji Action Plan included nine objectives for the school settings; four were based on nutrition and two on physical activity in schools, plus three general objectives, namely capacity building, social marketing and evaluation. Long-term change in nutritional behavior was difficult to achieve; a key contributor to this was the unhealthy food served in the school canteens. Whilst capacity-building proved to be one of the best mechanisms for intervening, it is important to consider the cultural and social factors influencing health behaviors and affecting specific groups.

Evidence and obesity prevention : developing evidence summaries to support decision making

Public health practitioners make decisions based on research evidence in combination with a variety of other influences. Evidence summaries are one of a range of knowledge translation options used to support evidence-informed decision making. The literature relevant to obesity prevention requires synthesis for it to be accessible and relevant to end-users. As part of a national collaboration on obesity prevention, we used a stakeholder-focused approach combined with transparent review methods to develop evidence summaries covering a selection of topics relevant to policy and practice in the context of childhood obesity prevention.
