IntroductionHealth disparities exist between rural and urban residents; in particular, rural residents have higher rates of chronic diseases and obesity. Evidence supports the effectiveness of policy and environmental strategies to prevent obesity and promote health equity. In 2009, the Centers for Disease Control and Prevention recommended 24 policy and environmental strategies for use by local communities: the Common Community Measures for Obesity Prevention (COCOMO); 12 strategies focus on physical activity. This review was conducted to synthesize evidence on the implementation, relevance, and effectiveness of physical activity–related policy and environmental strategies for obesity prevention in rural communities.MethodsA literature search was conducted in PubMed, PsycINFO, Web of Science, CINHAL, and PAIS databases for articles published from 2002 through May 2013 that reported findings from physical activity–related policy or environmental interventions conducted in the United States or Canada. Each article was extracted independently by 2 researchers.ResultsOf 2,002 articles, 30 articles representing 26 distinct studies met inclusion criteria. Schools were the most common setting (n = 18 studies). COCOMO strategies were applied in rural communities in 22 studies; the 2 most common COCOMO strategies were “enhance infrastructure supporting walking” (n = 11) and “increase opportunities for extracurricular physical activity” (n = 9). Most studies (n = 21) applied at least one of 8 non-COCOMO strategies; the most common was increasing physical activity opportunities at school outside of physical education (n = 8). Only 14 studies measured or reported physical activity outcomes (10 studies solely used self-report); 10 reported positive changes.ConclusionSeven of the 12 COCOMO physical activity–related strategies were successfully implemented in 2 or more studies, suggesting that these 7 strategies are relevant in rural communities and the other 5 might be less applicable in rural communities. Further research using robust study designs and measurement is needed to better ascertain implementation success and effectiveness of COCOMO and non-COCOMO strategies in rural communities.
Health equity is a public health priority, yet little is known about commitment to health equity in health departments, especially among chronic disease prevention practitioners whose work places them at the forefront of addressing the top contributors to disparities in morbidity and mortality. A random sample of state chronic disease practitioners (N=537) was surveyed on health equity commitments, partnerships, and needed skills. A small percent of respondents worked primarily on health equity (2%) and more (9%) included health equity as one of multiple work areas. Individuals who rated their work unit’s commitment to health equity as high were more likely to engage with sectors outside of health and rate their leaders as high quality and were less likely to identify skills gaps in their work unit. Opportunities exist to more fully address health equity in state public health practice through “big P” and “little p” policies, including those regarding resource allocation and staff training.
Purpose Physical activity (PA) has well-established health benefits, but most Americans do not meet national guidelines. In southeastern Missouri, trails have been developed to increase rates of PA. Although this has had success, broad-scale interventions will be needed to improve rates further. In this study, we surveyed residents of southeastern Missouri to identify ways to improve rates of PA. Methods We conducted a telephone survey in 2015 of adults (n = 524) from eight rural Missouri towns that had walking trails, regarding their activities and interests. Findings Forty percent of respondents reported both walking and meeting PA recommendations, 29% reported walking but not meeting PA recommendations, and the remainder did not walk or did not answer. Respondents who used the trails were significantly more likely to meet PA recommendations (odds ratio = 2.7; 95% confidence interval = 1.7, 4.5). Certain values and interests that may encourage PA or draw people to trails were common. Conclusions The group that walked but did not meet PA recommendations would be the ideal group to target for intervention, which could focus on their reported values and interests (e.g., personal relationships, being outdoors). Use of walking trails was associated with meeting PA recommendations.
Purpose This study examined municipal officials’ participation in built environment policy initiatives focused on land use design, transportation, and parks and recreation. Design Web-based cross-sectional survey. Setting 83 municipalities with 50,000 or more residents in 8 states. Subjects 453 elected and appointed municipal officials. Measures Outcomes included self-reported participation in land use design, transportation, and parks and recreation policy to increase physical activity. Independent variables included: respondent position; perceptions of importance, barriers and beliefs regarding physical activity and community design and layout; and physical activity partnership participation. Analysis Multivariable logistic regression models. Results Compared to other positions, public health officials had lower participation in land use design (78.3% vs. 29.0%), transportation (78.1% vs. 42.1%), and parks and recreation (67.1% vs. 26.3%) policy. Perceived limited staff was negatively associated with participation in each policy initiative. Perception of the extent to which physical activity was considered in community design and physical activity partnership participation were positively associated with participation in each. Perceived lack of collaboration was associated with less land use design and transportation policy participation, and awareness that community design affects physical activity was associated with more participation. Perceived lack of political will was associated with less parks and recreation policy participation. Conclusion Public health officials are under-represented in built environment policy initiatives. Improving collaborations may improve municipal officials’ policy participation.
The individual response to diet may be influenced by gene polymorphisms. This study hypothesized that ADRB2 (Gln27Glu, rs1042714 and Arg16Gly, rs1042713), ADRB3 (Trp64Arg, rs4994) and GHRL (Leu72Met, rs696217) polymorphisms moderate weight loss. The study was a seven weeks dietary weight loss intervention with Brazilian adult obese women (n = 109). The body mass index (BMI) was calculated and polymorphisms in these genes were assessed by real-time PCR assays. Two-way repeated-measures ANOVA (2 × 2) were used to analyze the intervention effect between polymorphisms and BMI over the period and after stratification for age and socioeconomic status (SES). The weight loss intervention resulted in decreased BMI over the seven-week period (p < 0.001), for high and low SES (p < 0.05) and mainly for participants with 30–49 y. The intervention did not result in a statistically significant difference in weight loss between polymorphism carriers and non-carriers, and although, the ADRB2, ADRB3 and GHRL polymorphisms did not moderate weight loss, the Gln27Glu polymorphism carriers showed a lower BMI compared to non-carriers in the low SES (p = 0.018) and the 30–39 y (p = 0.036) groups, suggesting a role for this polymorphism related to BMI control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
