Increasing community capacity to prevent childhood obesity: challenges, lessons learned and results from the Romp & Chomp intervention
Florentine P de Groot, Narelle M Robertson, Boyd A Swinburn, Andrea M de Silva-Sanigorski
BMC Public Health , 2010, DOI: 10.1186/1471-2458-10-522
Abstract: A mixed methods evaluation with three data sources was utilised. 1) Document analysis comprised assessment of the documented formative and intervention activities against a capacity building framework (five domains: Partnerships, Leadership, Resource Allocation, Workforce Development, and Organisational Development); 2) Thematic analysis of key informant interviews (n = 16); and 3) the quantitative Community Capacity Index Survey.Document analysis showed that the majority of the capacity building activities addressed the Partnerships, Resource Allocation and Organisational Development domains of capacity building, with a lack of activity in the Leadership and Workforce Development domains. The thematic analysis revealed the establishment of sustainable partnerships, use of specialist advice, and integration of activities into ongoing formal training for early childhood workers. Complex issues also emerged from the key informant interviews regarding the challenges of limited funding, high staff turnover, changing governance structures, lack of high level leadership and unclear communication strategies. The Community Capacity Index provided further evidence that the project implementation network achieved a moderate level of capacity.Romp & Chomp increased the capacity of organisations, settings and services in the Geelong community to support healthy eating and physical activity for young children. Despite this success there are important learnings from this mixed methods evaluation that should inform current and future community-based public health and health promotion initiatives.ANZCTRN12607000374460Health promoters and public health practitioners have existing knowledge about what 'works' in health promotion, however the evidence suggests that the majority of the positive outcomes are not sustained [1]. The focus therefore needs to be on ways to make the impacts of public health and health promotion initiatives sustainable, and community capacity building has eme

BMC Public Health , 2010, DOI: 10.1186/1471-2458-10-97
Abstract: This study involves the establishment of a birth cohort in disadvantaged communities in Victoria, Australia. Children will be followed for at least 18 months and the data gathered will explore longitudinal relationships and generate new evidence on the natural history of early childhood caries, the prevalence of the disease and relative contributions of risk and protective biological, environmental and behavioural factors. Specifically, the study aims to:1. Describe the natural history of early childhood caries (at ages 1, 6, 12 and 18 months), tracking pathways from early bacterial colonisation, through non-cavitated enamel white spot lesions to cavitated lesions extending into dentine.2. Enumerate oral bacterial species in the saliva of infants and their primary care giver.3. Identify the strength of concurrent associations between early childhood caries and putative risk and protective factors, including biological (eg microbiota, saliva), environmental (fluoride exposure) and socio-behavioural factors (proximal factors such as: feeding practices and oral hygiene; and distal factors such as parental health behaviours, physical health, coping and broader socio-economic conditions).4. Quantify the longitudinal relationships between these factors and the development and progression of early childhood caries from age 1-18 months.There is currently a lack of research describing the natural history of early childhood caries in very young children, or exploring the interactions between risk and protective factors that extend to include contemporary measures of socio-behavioural factors. This study will generate knowledge about pathways, prevalence and preventive opportunities for early childhood caries, the most prevalent child health inequality.Dental caries (decay) during childhood is largely preventable however it remains a significant and costly public health concern, identified as the most prevalent chronic disease of childhood [1].

BMC Public Health , 2010, DOI: 10.1186/1471-2458-10-65
Abstract: A mixed method and multi-level evaluation of the HPC:BAEW initiative will capture process, impact and outcome data and involve both local and state-wide evaluators. There will be a combined analysis across the five community intervention projects with outcomes compared to a comparison group using a cross-sectional, quasi-experimental design. The evaluation will capture process, weight status, socio-demographic, obesity-related behavioral and environmental data in intervention and comparison areas. This will be achieved using document analysis, paper-based questionnaires, interviews and direct measures of weight, height and waist circumference from participants (children, adolescents and adults).This study will add significant evidence on how to prevent obesity at a population level in disadvantaged and ethnically diverse communities. The outcomes will have direct influence on policy and practice and guide the development and implementation of future obesity prevention efforts in Australia and internationally.ACTRN12609000892213Obesity is a growing public health issue and there is now widespread agreement that the complex etiology of obesity requires a multifaceted approach to prevention [1-4]. Community-based interventions provide an opportunity for community assets to be utilized with efficiency and direction [3]. There is now emerging evidence of the effectiveness of community-based and community-wide, multi-strategy approaches to obesity prevention [1,5-9].A community-based, capacity-building approach aims to promote sustainable skill development, strengthen communities and increase the ability of individuals to effectively address and improve health outcomes [10,11]. Such an approach has the potential to influence the underlying social and economic determinants of health in a flexible, sustainable, equitable and safe manner [12]. To determine the sustainability of effective intervention activities, evaluation is required both in the intermediate and long term [1

Abstract: A convenience sample of participants (n = 90) recruited through preschools and the community in Geelong, Australia provided dietary data for their child via EPAQ and interviewer-administered 24-hour dietary recall (24 hr-recall). Comparison of mean food and beverage group servings between the EPAQ and 24 hr-recall was conducted and Spearman rank correlations were computed to examine the association between the two methods.Mean servings of food/beverage groups were comparable between methods for all groups except water, and significant correlations were found between the servings of food and beverages using the EPAQ and 24-hr recall methods (ranging from 0.57 to 0.88).The EPAQ is a simple and useful population-level tool for estimating the intake of obesity-related foods and beverages in children aged two to five years. When compared with 24-hour recall data, the EPAQ produced an acceptable level of relative validity and this short survey has application for population monitoring and the evaluation of population-based obesity prevention interventions for young children.The increasing prevalence of obesity in children has been partially attributed to the over-consumption of energy-dense, nutrient poor foods and sugar-sweetened beverages [1-6]. Fast food, packaged snacks, sweet drinks, and biscuits (cookies) have also been shown to contribute significant amounts of energy to children's diets in Australia [7,8], as in other Western countries.In general, dietary assessment tools for children assess the whole diet and are focused on individual nutritional adequacy or excess. There is, however, a demand for validated tools that specifically assess the intake of energy dense foods and sugar sweetened beverages which are easily and cheaply administered to large groups for population monitoring and the evaluation of obesity-related health promotion programs. Such tools are particularly lacking for use in populations of young children [9,10] which requires proxy reporting from

PLOS ONE , 2011, DOI: 10.1371/journal.pone.0024805
Abstract: Objectives A number of cross-sectional and prospective studies have now been published demonstrating inverse relationships between diet quality and the common mental disorders in adults. However, there are no existing prospective studies of this association in adolescents, the onset period of most disorders, limiting inferences regarding possible causal relationships. Methods In this study, 3040 Australian adolescents, aged 11–18 years at baseline, were measured in 2005–6 and 2007–8. Information on diet and mental health was collected by self-report and anthropometric data by trained researchers. Results There were cross-sectional, dose response relationships identified between measures of both healthy (positive) and unhealthy (inverse) diets and scores on the emotional subscale of the Pediatric Quality of Life Inventory (PedsQL), where higher scores mean better mental health, before and after adjustments for age, gender, socio-economic status, dieting behaviours, body mass index and physical activity. Higher healthy diet scores at baseline also predicted higher PedsQL scores at follow-up, while higher unhealthy diet scores at baseline predicted lower PedsQL scores at follow-up. Improvements in diet quality were mirrored by improvements in mental health over the follow-up period, while deteriorating diet quality was associated with poorer psychological functioning. Finally, results did not support the reverse causality hypothesis. Conclusion This study highlights the importance of diet in adolescence and its potential role in modifying mental health over the life course. Given that the majority of common mental health problems first manifest in adolescence, intervention studies are now required to test the effectiveness of preventing the common mental disorders through dietary modification.

Abstract: This is a two-stage study using a mixed methods research approach. The first stage involves qualitative interviews of a sub-sample of recruited parents to develop an understanding of the processes involved in drink choice, and inform the development of the Discrete Choice Experiment analysis and the measurement instruments to be used in the second stage. The second stage involves the establishment of a prospective birth cohort of 500 children from disadvantaged communities in rural and regional Victoria, Australia (with and without water fluoridation). This longitudinal design allows measurement of changes in the child's diet over time, exposure to fluoride sources including water, dental caries progression, and the risk of childhood obesity.This research will provide a unique contribution to integrated health, education and social policy and program directions, by providing clearer policy relevant evidence on strategies to counter social and environmental factors which predispose infants and children to poor health, wellbeing and social outcomes; and evidence-based strategies to promote health and prevent disease through the adoption of healthier lifestyles and diet. Further, given the absence of evidence on the processes and effectiveness of contemporary policy implementation, such as community water fluoridation in rural and regional communities it's approach and findings will be extremely informative.Dental caries (decay) is one of the most common diseases affecting children [1,2], in Australia and elsewhere [3], developing very early in life with detrimental impacts [4,5]. More than one third of four-year-old children experience caries in their deciduous (primary) teeth and, alarmingly, the majority of this caries experience is in the form of untreated decay [1,2]. Tooth decay can cause pain, discomfort and difficulty eating, and untreated tooth decay can become so severe that children must undergo tooth extraction, usually under general anaesthetic.In Australi

Abstract: The evaluation is mixed method and cross sectional and aims to:1) Determine if K-GFYL award status is associated with more health promoting environments in schools/services compared to those who are members only;2) Determine if children attending K-GFYL award schools/services have higher levels of healthy eating and physical activity-related behaviors compared to those who are members only;3) Examine the barriers to implementing and achieving the K-GFYL award; and4) Determine the economic cost of implementing K-GFYL in primary schoolsParent surveys will capture information about the home environment and child dietary and physical activity-related behaviors. Environmental questionnaires in early childhood settings and schools will capture information on the physical activity and nutrition environment and current health promotion activities. Lunchbox surveys and a set of open-ended questions for kindergarten parents will provide additional data. Resource use associated with the intervention activities will be collected from primary schools for cost analysis.The K-GFYL award program is a community-wide intervention that requires a comprehensive, multi-level evaluation. The evaluation design is constrained by the lack of a non-K-GFYL control group, short time frames and delayed funding of this large scale evaluation across all intervention settings. However, despite this, the evaluation will generate valuable evidence about the utility of a community-wide environmental approach to preventing childhood obesity which will inform future public health policies and health promotion programs internationally.ACTRN12609001075279Currently, there is only limited evidence available about effective strategies to prevent childhood obesity. However community-based approaches to prevent childhood obesity that are multi-sector and multi-strategy show promise as being effective and also have the potential to be equitable, sustainable and cost-effective [1-8].

Abstract: in order to evaluate the diversity and infestation level of teredinidae wood-boring molluscs, ten satations were chosen along the coast of rio de janeiro state. using five pine-wood panels in each station, it was possible to distinguish five areas according to species dominance. ilha grande bay is characterized by the dominance of lyrodus floridanus (bartsch, 1922); sepetiba bay, by bankia fimbriatula moll & roch, 1931, tijuca lagoon by teredo navalis linnaeus, 1758; guanabara bay by notoredo knoxi (bartsch, 1917) and araruama lagoon by teredo furcifera martens, 1894. specific composition and dominance of these species were due mainly to abiotic factors such as salinity whereas infestation level was associated not only to salinity but also to other factors such as the quantity and quality of fouling, the presence of larval dispersion focus and the wood supply in each area.

Abstract: O número de matrículas de crian as com necessidades educacionais especiais nas escolas públicas tem aumentado anualmente em todo país, com a implanta o de uma política de educa o inclusiva fomentada pelo Governo Federal. As escolas municipais, hoje responsáveis por grande parte dos alunos do Ensino Fundamental, têm sido o grande foco do Programa Educa o Inclusiva: Direito à Diversidade, em implanta o desde 2004. Diante desse panorama, o propósito deste texto é analisar alguns aspectos relativos à implanta o da política de Educa o Inclusiva na rede municipal de uma cidade do interior do país. Para tanto, foi coletado material empírico em salas de aulas inclusivas e em institui es municipais responsáveis pelo atendimento aos alunos com necessidades educacionais especiais, durante um semestre letivo. O material foi analisado considerando-se diferentes aspectos da organiza o escolar e de atendimento aos alunos. As análises apontam para o respeito à legisla o pertinente à implanta o da Educa o Inclusiva, quanto à matrícula, número de alunos por sala, forma o mínima do quadro docente, entre outros. No entanto, indicam também que o cumprimento desses aspectos n o garante a efetividade do processo escolar, visto que a lógica do custo-benefício, adotada nessa política, implica precariedade dos atendimentos oferecidos.

Abstract: the objective of this work was to determine the most profitable management method, among the variation of age and thinning intensities, site index, interest rates, wood prices and last cutting age. to achieve this goal, data of a thinning experiment established at empresa copener florestal ltda, bahia, were used. the prediction system used was developed by clutter (1963). the economic evaluation method used was the equivalent periodic benefit (bpe). the results showed that the method with thinning was economically better than the method without thinning, but as the thinning intensity increased the bpe values tended to decrease. also, lower interest rates and higher site indexes were observed to increase the method profits. the method that provided the greatest profit was obtained with thinning at four and last cut at nine years of age. the variables site index, interest rate and establishment cost did not significantly influence the determination of the most profitable method, that is, the most profitable method remained the thinning at four and last cut at nine years of age. on the other hand, the variable thinned wood price influenced the determination of the most profitable method. the increase in price according to the harvesting age resulted in thinning at six and last cut at nine years of age as the most profitable method. similarly, the increase in wood price of the last cut according to the cutting age resulted in thinning at four and last cut at 12 years of age as the most profitable method. the simulation of increasing the price of thinned and last cut wood, at the same time, generated as the most profitable method thinning at six and last cut at 12 years of age. it was concluded that there was a direct influence of variables prices of thinned and last cut wood on the determination of the most profitable method.
