To examine the prevalence and association of activity/participation limitation with trying to lose weight and weight loss practices (eating fewer calories, physical activity, or both) among overweight and obese adults in the United States.Eligible adults were 20 years of age or older with a body mass index (BMI)or= 25 kg/m(2) (n = 5608) who responded to standard physical functioning questions included in the 1999-2002 National Health and Nutrition Examination Survey, a continuous survey of the civilian non-institutionalized US population.Obese (BMIor= 30) men with vs. without activity/participation limitations were more likely to try to lose weight (OR = 1.59, 95% CI 1.05-2.41). This was not the case for overweight women and men (BMI 25-29.9), or obese women. Among adults trying to lose weight, reducing calorie consumption was common (63%-73%, men, 67%-76%, women). Overweight women with vs without activity/participation limitations had significantly reduced likelihood of attaining recommended physical activity (OR = 0.56, 95% CI 0.36-0.89). Obese adults were more likely to try to lose weight if they attributed their limitation to body weight (OR = 1.78, 95% CI 1.11-2.88) or diabetes (OR = 1.86, 95% CI 1.01-3.43) compared to other causes. Overweight and obese adults who attributed activity/participation limitations to mental health, musculoskeletal, or cardiovascular problems were equally likely to attempt weight loss when respondents with each condition were compared to respondents without the condition.These results verify the importance of adequate subjective health assessment when developing individual weight loss plans, and may help guide weight management professionals in the development and delivery of more personalized care.

BACKGROUND: There is limited population-based data on diet and physical activity behaviors and weight loss among users of prescription weight loss medications. Most findings are from clinical settings or from research that includes organized behavioral programs. METHODS: We analyzed data from the 1998 Behavioral Risk Factor Surveillance System, an annual telephone survey conducted in all fifty states, the District of Columbia and Puerto Rico. The sample consisted of 135,435 noninstitutionalized adults aged 18 years old and older. We determined the prevalence and odds of prescription weight loss medication use, odds of 10% weight loss, and among current weight loss medication users, the prevalence and odds for diet and physical activity behaviors. RESULTS: 10.2% of obese women and 3.1% of obese men reported using prescription weight loss medications in the past 2 years. Of users, 28.2% had lost at least 10% of their pretreatment body weight. The odds of losing at least this much weight were higher among women, those who usually consumed/= 5 fruits and vegetables daily and those who met physical activity recommendations. Among current prescription weight loss medication users, 26.7% reported both eating fewer calories and meeting recommended leisure-time physical activity levels (40% of any group met both). Of those meeting both recommendations, almost half (47.2%) had lost 10% of their pretreatment body weight. Of current users, 9% reported using the medications for weight maintenance. CONCLUSIONS: Only 26.7% of prescription weight loss medication users reported following recommended diet and physical activity behaviors. Further research is needed to assess whether behavioral changes are associated with greater weight loss and maintenance among prescription weight loss medication users.

IntroductionResidents of rural communities in the United States are at higher risk for obesity than their urban and suburban counterparts. Policy and environmental-change strategies supporting healthier dietary intake can prevent obesity and promote health equity. Evidence in support of these strategies is based largely on urban and suburban studies; little is known about use of these strategies in rural communities. The purpose of this review was to synthesize available evidence on the adaptation, implementation, and effectiveness of policy and environmental obesity-prevention strategies in rural settings.MethodsThe review was guided by a list of Centers for Disease Control and Prevention Recommended Community Strategies and Measurements to Prevent Obesity in the United States, commonly known as the “COCOMO” strategies. We searched PubMed, Cumulative Index of Nursing and Allied Health Literature, Public Affairs Information Service, and Cochrane databases for articles published from 2002 through 2013 that reported findings from research on nutrition-related policy and environmental strategies in rural communities in the United States and Canada. Two researchers independently abstracted data from each article, and resolved discrepancies by consensus.ResultsOf the 663 articles retrieved, 33 met inclusion criteria. The interventions most commonly focused on increasing access to more nutritious foods and beverages or decreasing access to less nutritious options. Rural adaptations included accommodating distance to food sources, tailoring to local food cultures, and building community partnerships.ConclusionsFindings from this literature review provide guidance on adapting and implementing policy and environmental strategies in rural communities.
