RESUMO
BACKGROUND: The reorientation of primary health care towards prevention is fundamental to addressing the rising burden of chronic disease. However, in Australia, cardiovascular disease prevention practice in primary health care is not generally consistent with existing guidelines. The Model for Prevention study was a whole-of-system cardiovascular disease prevention intervention, with one component being enhanced lifestyle modification support and addition of a health coaching service in the general practice setting. To determine the feasibility of translating intervention outcomes into real world practice, implementation work done by stakeholders was examined using Normalisation Process Theory as a framework. METHODS: Data was collected through interviews with 40 intervention participants and included general practitioners, practice nurses, practice managers, lifestyle advisors and participants. Data analysis was informed by normalisation process theory constructs. RESULTS: Stakeholders were in agreement that, while prevention is a key function of general practice, it was not their usual work. There were varying levels of engagement with the intervention by practice staff due to staff interest, capacity and turnover, but most staff reconfigured their work for required activities. The Lifestyle Advisors believed staff had varied levels of interest in and understanding of, their service, but most staff felt their role was useful. Patients expanded their existing relationships with their general practice, and most achieved their lifestyle modification goals. While the study highlighted the complex nature of the change required, many of the new or enhanced processes implemented as part of the intervention could be scaled up to improve the systems approach to prevention. Overcoming the barriers to change, such as the perception of CVD prevention as a 'hard sell', is going to rely on improving the value proposition for all stakeholders. CONCLUSIONS: The study provided a detailed understanding of the work required to implement a complex cardiovascular disease prevention intervention within general practice. The findings highlighted the need for multiple strategies that engage all stakeholders. Normalisation process theory was a useful framework for guiding change implementation.

This paper reports on a qualitative study exploring the capacity of the community sector to support a whole-of-system response to cardiovascular disease prevention in primary health care. As a component of the Model for Prevention (MoFoP) study, community-based lifestyle modification providers were recruited in the Australian Capital Territory to participate in focus group discussions; 34 providers participated across six focus groups: 20 Allied Health Professionals (four groups) and 14 Lifestyle Modification Program providers (two groups). Thematic analysis of focus group transcripts was undertaken using a mixed deductive and inductive approach. Participant responses highlight several barriers to their greater contribution to cardiovascular disease prevention. These included that prevention activities are not valued, limited sector linkages, inadequate funding models and the difficulty of behaviour change. Findings suggest that improvements in the value proposition of prevention for all stakeholders would be supported by improved funding mechanisms and increased opportunities to build relationships across health and community sectors.

The study objectives were (1) to determine the variation in prevalence of overweight between school communities, (2) to evaluate the relationship between cardiorespiratory fitness and the probability of being overweight among different school communities, and (3) to test whether this relationship varies between school communities. Using a repeated cross-sectional design, data from 31,424 (15,298 girls, 16,126 boys) Australian school children who had objective assessments of body composition and physical performance were used. Ninety-one schools located across 5 states and territories were included. Independent samples were taken across 12 school years (2000-2011). Analysis used generalised linear mixed models in R with a two-level hierarchical structure-children, nested within school communities. Predictor variables considered were: level 1-gender, age, cardiorespiratory fitness and year of measurement; level 2-school community. A total of 24.6% of the children were overweight and 69% were of low fitness. Variation in the prevalence of overweight between school communities was significant, ranging from 19% to 34%. The probability of being overweight was negatively associated with increasing cardiorespiratory fitness. The relationship was steepest at low fitness and varied markedly between school communities. Children of low fitness had probabilities of being overweight ranging between 26% and 75% depending on school community, whereas those of high fitness had probabilities of <2%. Our findings suggest that most might be gained from a public health perspective by focusing intervention on the least fit children in the worst-performing communities.

BACKGROUND: There is growing recognition that a sedentary lifestyle is being driven, at least in part, by environmental factors that affect individuals' physical activity choices and health behaviours. In other words, the environments in which we live, and with which we interact, have become ones that encourage lifestyle choices that decrease physical activity and encourage over-consumption of foods. However, evidence from community-led interventions to change local neighbourhood environments to support physical activity and healthy eating is lacking. This article summarises the research protocol developed to evaluate a community-led intervention "My Health Matters" aimed at reducing health inequalities relating to increasing physical activity and healthy eating as defined by community members themselves. METHODS/DESIGN: This study includes three of the most deprived electoral wards in Stoke-on-Trent. In each of these areas, environmental factors including proximity of physical activity spaces, greenspace and leisure facilities, neighbourhood connectivity and walkability, land-use-mix and population density, traffic, safety and crime, and food outlets will be mapped using Geographical Information Systems (GIS). A community postal survey of randomly selected addresses assessing environmental characteristics relating to physical activity, perceived health status, social capital, fruit and vegetable consumption and levels of physical activity will be undertaken (baseline and at 2 year follow-up). Based on baseline findings an intervention will be designed and implemented over a 2 year period that includes the following; use of community participatory research to build effective community partnerships; use of partnership consensus to identify, prioritise and design intervention(s) related to specific health disparities; recruitment of local residents to help with the delivery and sustainability of target intervention(s); and the development of local systems for ongoing monitoring and evaluation of the intervention(s). DISCUSSION: A community-led and multidisciplinary approach to modifying environmental factors that support and reinforce healthful behaviours may be more successful than focusing on individual behaviour change as this approach does not exclusively rely upon individual will and capacity.Study findings will be collated in 2012 and, if successful in improving levels of physical activity and healthy eating, will help to inform the design of a larger area-based, cluster randomized controlled trial to determine effectiveness.

OBJECTIVE: To explore the relative importance of the perceived physical and social neighbourhood environment for physical and mental health. METHODS: A representative random sample of adults was recruited from 10 areas across Stoke-on-Trent, UK (June-September 2007). Interview-administered surveys were used to record data on the perceived neighbourhood environment (physical and social), self-reported health, and socio-demographics. Multiple regression analysis was used to explore independent associations between environmental factors and physical and mental health. RESULTS: Independent physical and social environmental factors respectively explained 6.0% and 3.2% of variability in physical health and 2.8% and 4.4% of variability in mental health. Diversity of land use was the strongest and only physical environmental predictor of physical health (Beta=0.27, p<0.001), explaining more variability than social environmental factors combined. Conversely, social support was the most important (and only) social environmental factor for mental health (Beta=-0.20, p<0.001); again, this explained more variability in mental health than the combined effect of four physical environmental predictors. CONCLUSION: Perceived physical and social environmental characteristics were important for physical and mental health, independent of socio-demographic factors. Living in neighbourhoods with greater land use diversity appears particularly important for physical health, whereas social support appears more closely linked to mental health.

RATIONALE: Residents of neighbourhoods with high destination accessibility (higher population density, more-interconnected streets, and better access to services, public transport and parks) are more physically active. Evidence on the factors that underlie these associations is sparse and inconsistent. OBJECTIVE: We examined (1) five socio-demographic and four non-destination perceived neighbourhood attributes as moderators of the relationship between objectively-assessed destination accessibility and moderate-to-vigorous physical activity (MVPA); (2) perceived indicators of destination accessibility as mediators of those relationships; and, (3) the generalizability of findings across 14 cities. METHODS: Data were from the International Physical Activity and Environment Network (IPEN) Adult study (Nâ¯=â¯6822), which provided comparable objective and perceived environmental variables and accelerometer-based MVPA from 14 cities across 10 countries. Mediation and mediation moderation analyses were performed. RESULTS: Objective net residential density, public transport density, and number of parks in the neighbourhood were consistently associated with MVPA across all examined socio-demographic groups and non-destination perceived neighbourhood characteristics. However, only the association between number of parks and MVPA was mediated by its conceptually-comparable perceived indicator. While the associations of objective intersection density and land use mix with MVPA were moderated by both gender and perceived pedestrian infrastructure/safety, only the latter moderating effects were mediated by the conceptually-comparable perceived indicators. Perceived neighbourhood safety and/or aesthetics moderated the associations of objective ratio of retail/civic land to total area and distance to nearest transport stop with MVPA. These associations were not mediated by the conceptually-comparable perceived indicators. CONCLUSION: Densely populated neighbourhoods with access to public transport and parks have the potential to significantly and equitably contribute to adults' MVPA on a global scale. Perceived neighbourhood aesthetics, pedestrian-friendliness and safety can magnify the positive effects of mixed-use neighbourhoods on residents' MVPA by interacting with the perceived ease of access to a variety of destinations.

BACKGROUND: Reversing decline in physical fitness and increase in excess body weight in school children are considered major public health challenges. We evaluated a proposed model to integrate a screening and healthy exercise, eating, and lifestyle program (HEELP) into primary schools in Canberra, Australia. Objectives were: (1) to establish body status and physical competencies of 5- to 10-year-old children; (2) to evaluate the service's impact on body status and physical fitness; and (3) to gauge parent/guardian and school perspectives on the service. METHODS: A mixed-methods approach was used over 4 school years, 2010-2013. Primary evaluation used direct quantitative measurement. Confirmatory qualitative methods were implemented in the last 2 years. RESULTS: The service was delivered on 71 occasions involving 25 schools; 7750 children were screened and 709 completed all aspects of the HEELP evaluation. Over 60% of children screened had 2 or more measures that would benefit from remedial intervention. CONCLUSIONS: All body status and physical fitness measures showed small beneficial changes on a population basis immediately after the HEELP. Further benefit did not accrue at 6 months after the program. Semistructured interviews with schools and parent/guardian surveys confirmed some beneficial effects observed by direct quantitative measurement.

OBJECTIVES: To provide two foundation elements of a proposed new system to support children's physical and body status development throughout primary school: (a) age and gender appropriate achievement (anthropometric) standards and (b) a system of monitoring, feedback and support. DESIGN: Repeated cross-sectional sampling involving 91 schools across 5 Australian States and Territories between 2000 and 2011. METHODS: Anthropometric data from 29,928 (14,643 girls, 15,285 boys) Australian children aged between 5 and 12.5 years were used to develop progression standards (norm centiles) covering the primary school years. Measures used were: height, weight, body mass index, per cent body fat, grip strength, standing long jump, cardiorespiratory fitness, sit-ups and sit-and-reach. These norms were then used to develop a Physical Activity and Lifestyle Management (PALM) system that could form the basis for progression, monitoring and reporting of anthropometric achievement standards for children. RESULTS: Tables and representative centile curves (3rd, 15th, 50th, 85th and 97th) for each gender and half-year age group were produced. An illustrative example of the PALM system in operation was also provided. CONCLUSIONS: Our research provides gender and half-year age specific anthropometric standards for Australian primary school children. Furthermore, we have developed a monitoring and progression system that could be embedded in school communities to help address the prevalence of underweight, overweight and obesity and decline in physical fitness standards. The proposed system is designed on behalf of children and families and would be administered through school settings. Change, where needed, would be delivered by the supporting school community.

Globally, scabies affects more than 130 million people at any time. In the developed world, outbreaks in health institutions and vulnerable communities result in a significant economic burden. A review of the literature demonstrates the emergence of resistance toward classical scabicidal treatments and the lack of effectiveness of currently available scabicides in reducing the inflammatory skin reactions and pyodermal progression that occurs in predisposed patient cohorts. Tea tree oil (TTO) has demonstrated promising acaricidal effects against scabies mites in vitro and has also been successfully used as an adjuvant topical medication for the treatment of crusted scabies, including cases that did not respond to standard treatments. Emerging acaricide resistance threatens the future usefulness of currently used gold standard treatments (oral ivermectin and topical permethrin) for scabies. The imminent development of new chemical entities is doubtful. The cumulative acaricidal, antibacterial, antipruritic, anti-inflammatory, and wound healing effects of TTO may have the potential to successfully reduce the burden of scabies infection and the associated bacterial complications. This review summarizes current knowledge on the use of TTO for the treatment of scabies. On the strength of existing data for TTO, larger scale, randomized controlled clinical trials are warranted.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death globally, and accounted for nearly 31% of all deaths in Australia in 2011. The primary health care sector is at the frontline for addressing CVD, however, an evidence-to-practice gap exists in CVD risk assessment and management. General practice plays a key role in CVD risk assessment and management, but this sector cannot provide ongoing lifestyle change support in isolation. Community-based lifestyle modification services and programs provided outside the general practice setting have a key role in supporting and sustaining health behavior change. Fostering linkages between the health sector and community-based lifestyle services, and creating sustainable systems that support these sectors is important. OBJECTIVE: The objective of the study Model for Prevention (MoFoP) is to take a case study approach to examine a CVD risk reduction intervention in primary health care, with the aim of identifying the key elements required for an effective and sustainable approach to coordinate CVD risk reduction across the health and community sectors. These elements will be used to consider a new systems-based model for the prevention of CVD that informs future practice. METHODS: The MoFoP study will use a mixed methods approach, comprising two complementary research elements: (1) a case study, and (2) a pre/post quasi-experimental design. The case study will consider the organizations and systems involved in a CVD risk reduction intervention as a single case. The pre/post experimental design will be used for HeartLink, the intervention being tested, where a single cohort of patients between 45 and 74 years of age (or between 35 and 74 years of age if Aboriginal or Torres Strait Islander) considered to be at high risk for a CVD event will be recruited through general practice, provided with enhanced usual care and additional health behavior change support. A range of quantitative and qualitative data will be collected. This will include individual health and well being data collected at baseline and again at 12 months for HeartLink participants, and systems related data collected over the period of the intervention to inform the case study. RESULTS: The intervention is currently underway, with results expected in late 2015. CONCLUSIONS: Gaining a better understanding of CVD prevention in primary health care requires a research approach that can capture and express its complexity. The MoFoP study aims to identify the key elements for effective CVD prevention across the health and community sectors, and to develop a model to better inform policy and practice in this key health priority area for Australia.
RESUMO
PURPOSE: Environmental changes are potentially effective population-level physical activity (PA) promotion strategies. However, robust multisite evidence to guide international action for developing activity-supportive environments is lacking. We estimated pooled associations of perceived environmental attributes with objectively measured PA outcomes, between-site differences in such associations, and the extent to which perceived environmental attributes explain between-site differences in PA. METHODS: This was a cross-sectional study conducted in 16 cities located in Belgium, Brazil, Colombia, Czech Republic, Denmark, China, Mexico, New Zealand, Spain, United Kingdom, and United States of America. Participants were 6968 adults residing in administrative units stratified by socioeconomic status and transport-related walkability. Predictors were 10 perceived neighborhood environmental attributes. Outcome measures were accelerometry-assessed weekly minutes of moderate-to-vigorous PA (MVPA) and meeting the PA guidelines for cancer/weight gain prevention (420 min·wk of MVPA). RESULTS: Most perceived neighborhood attributes were positively associated with the PA outcomes in the pooled, site-adjusted, single-predictor models. Associations were generalizable across geographical locations. Aesthetics and land use mix-access were significant predictors of both PA outcomes in the fully adjusted models. Environmental attributes accounted for within-site variability in MVPA, corresponding to an SD of 3 min·d or 21 min·wk. Large between-site differences in PA outcomes were observed; 15.9%-16.8% of these differences were explained by perceived environmental attributes. All neighborhood attributes were associated with between-site differences in the total effects of the perceived environment on PA outcomes. CONCLUSIONS: Residents' perceptions of neighborhood attributes that facilitate walking were positively associated with objectively measured MVPA and meeting the guidelines for cancer/weight gain prevention at the within- and between-site levels. Associations were similar across study sites, lending support for international recommendations for designing PA-friendly built environments.

PURPOSE: Epidemiological studies of chronic disorders need to consider more responsive outcomes, particularly those that manifest themselves across a defined population over a shorter time period, to improve our ability to detect the causes of and intervene in the global epidemics of today. We explore the use of hospital episode statistics as a candidate for this role and estimate the strength of the association of circulatory disease-related events with physical inactivity, considered here as an undesirable health behavior. SETTINGS PATIENTS AND METHODS: The primary research was set in a mid-sized city in central England. Aggregation was at output area level (comprising ~300 residents); 51 of which were included. A random sample of 761 adults was selected to obtain estimates of the mean level of physical activity within each area. Circulatory disease hospital events were recorded and aggregated by output area over a 2-year period. Hierarchical linear modeling was used to establish the strength of the association between area-level physical activity and circulatory disease events. Sex, age, and reporting quarter were included as additional individual-level explanatory variables. RESULTS: Areas reporting greater activity were less likely (event rate ratio = 0.855; 95% confidence interval [CI]: 0.78-0.94) to have a circulatory disease event, as were females (0.593; 95% CI: 0.47-0.75). Areas with older residents (1.578; 95% CI: 1.5-1.66) and later reporting quarters (1.095; 95% CI: 1.04-1.15) were more likely to report circulatory disease events. CONCLUSION: This study supports the use of hospital episode statistics as an outcome measure in the epidemiology of circulatory disease and reaffirms the potential importance of physical inactivity in the disease process.
RESUMO
Reducing population physical inactivity has been declared a global public health priority. We report a detailed multi-level analysis of small area indices and individual factors as correlates of physical activity in deprived urban areas. Multi-level regression analysis was used to investigate environmental and individual correlates of physical activity. Nine individual factors were retained in the overall model, two related to individual intentions or beliefs, three to access to shops, work or fast food outlets and two to weather; age and gender being the other two. Four area level indices related to: traffic, road casualties, criminal damage and access to green space were important in explaining variation in physical activity.

This study was set up to test an ecological intervention using a pragmatic cluster randomised controlled design (RCT) aimed at increasing physical activity (PA) within the community in a deprived inner-city area in the UK. The research will provide a detailed mapping (using Graphical Information Systems GIS) of the environment at lower super output area (SOA) level in Stoke-on-Trent (SoT) and will evaluate the relationship between the environment, PA behaviour, health and healthcare utilisation. The environmental mapping will aggregate data from a wide range of available databases, augmented by local data gathering and validation, to produce a comprehensive geo-coded map of 10 SOAs (covering a population ~15,000). GIS will be used to derive indices through which to evaluate the relationship between environmental characteristics and levels of physical activity and health, using Hierarchical Linear Modelling (HLM). Environmental indices used will include: proximity of PA spaces and facilities, street connectivity, land use mix, population density, mass transport provision, traffic, safety, crime, proximity of food outlets and shops, "Walkability Index", weather and indices of multiple deprivation (IMD). The areas for mapping, baseline assessment and intervention will be considered in two parts, a) community-based and b) schools-based. The effectiveness of the community-based intervention will be assessed by an independent panel survey conducted at baseline and at 2 years follow-up, with an expected 10% increase in the proportion of the population more active in the intervention arm. Effectiveness of the schools-based intervention will be designed to detect an increase of ~15 min/day in school children's moderate to vigorous PA (MVPA). Resource use, cost, willingness to pay and incidental consequences data will be collected alongside the community-based intervention to enable economic modelling from health and social care, societal, other public service and participant perspectives. Findings from the project will inform public policy for increasing population PA and improving neighbourhoods and urban design.
