Diet and physical activity behavior among users of prescription weight loss medications
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
Nutrition-related policy and environmental strategies to prevent obesity in rural communities: A systematic review of the literature, 2002-2013
Introduction Residents 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. Methods The 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. Results Of 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. Conclusions Findings from this literature review provide guidance on adapting and implementing policy and environmental strategies in rural communities
Adherence to Antimicrobial Inhalational Anthrax Prophylaxis among Postal Workers, Washington, D.C., 2001
In October 2001, two envelopes containing Bacillus anthracis spores were processed at the Washington, D.C., Processing and Distribution Center of the U.S. Postal Service; inhalational anthrax developed in four workers at this facility. More than 2,000 workers were advised to complete 60 days of postexposure prophylaxis to prevent inhalational anthrax. Interventions to promote adherence were carried out to support workers, and qualitative information was collected to evaluate our interventions. A quantitative survey was administered to a convenience sample of workers to assess factors influencing adherence. No anthrax infections developed in any workers involved in the interventions or interviews. Of 245 workers, 98 (40%) reported full adherence to prophylaxis, and 45 (18%) had completely discontinued it. Experiencing adverse effects to prophylaxis, anxiety, and being <45 years old were risk factors for discontinuing prophylaxis. Interventions, especially frequent visits by public health staff, proved effective in supporting adherence

Determinants and functional consequences of adult obesity in Egyptian men and women.
The purpose of this study was to investigate the prevalence and present food intake and morbidity patterns of obesity in men (n = 162) and women (n = 286) 15 to 80 years of age. Data were collected in a community-based longitudinal study from 1983 to 1985 in a semi-rural Egyptian village. Degree of obesity was estimated using body mass index (BMI) and a derived measure of adiposity from principal components analysis of several anthropometric variables. BMI was significantly correlated with other available measures of adiposity, lean mass and age and uncorrelated with height. Derived measures of adiposity were related to all other measures of relative weight and adiposity in both sexes and related to age in women. Within agricultural households, men were shorter and had higher adiposity levels, and women were taller than non-agricultural households. The presence of chronic disease was unrelated to BMI in men. However, chronic disease and respiratory difficulties occurred more often in overweight and obese women. There was no difference in the prevalence of acute illness for lean and normal weight compared to overweight and obese men. Skin problems occurred more often in overweight and obese women. There was a risk of low pregnancy weight gain across the range of BMI. Obese women produced heavier infants than normal weight or overweight women; overweight women produce heavier infants than leaner women. Infant birthweight was predicted by prepregnancy BMI or adiposity level, pregnancy weight gain and height. For men, animal products contributed to the higher intakes of fat, vitamin A and zinc in overweight and obese, and fats and oils contributed to higher vitamin E intakes. For women, bread contributed to higher intakes of dietary fiber and lower intakes of calcium in overweight and obese
A conceptual model of the food and nutrition system
The food system is a widely used concept, but few systematic frameworks model the full scope and structure of the food and nutrition system. Bibliographic searches, a modified Delphi technique, focus groups and interviews with experts on the topic were conducted to identify existing models of agriculture, food, nutrition, health and environmental systems. These models were examined, classified and synthesized into an integrated conceptual model of the food and nutrition system. Few existing models broadly described the system and most focused on one disciplinary perspective or one segment of the system. Four major types of models were identified: food chains, food cycles, food webs and food contexts. The integrated model developed here included three subsystems (producer, consumer, nutrition) and nine stages (production, processing, distribution, acquisition, preparation, consumption, digestion, transport, metabolism). The integrated model considers the processes and transformations that occur within the system and relationships between the system and other systems in the biophysical and social environments. The integrated conceptual model of the food and nutrition system presents food and nutrition activities as part of a larger context and identifies linkages among the many disciplines that deal with the food and nutrition system.model food nutrition health agriculture diet systems
