Relationship between density, proximity, and diversity of food outlets and adult overweight/obesity in Nevada
type: CreativeWork
description: AbstractAdult overweight and obesity is a rising epidemic that is a major public health concern. Studies suggest that the food environment may be related to the prevalence of overweight and obesity.Objective: This is the first statewide study to examine the density, proximity and diversity of food outlets and adult overweight/obesity prevalence in Nevada. Methods: Population demographics, health status, and health risk behaviors were obtained from 2007- 2008 Nevada Behavior Risk Factor Surveillance Systems (BRFSS), and food outlets information was obtained from Environmental Systems Research Institute, Geographic Information System database. A total number of 2251 subjects were included in the study analysis. Subjects were geocoded and half, 1, and 3 miles buffer zones were created around subjects¡¯ residences. Density of food outlets was measured within each buffer zone and distance to the closest food outlet was determined for each subject. The outcome variable was being overweight/obese (BMI¡Ý25 kg/m2) or neither (BMI<25 kg/m2). Multiple logistic regression was used to estimate the odds ratio of being overweight/obese, and to control for demographics (age, sex, income, employment, marital status, education, race/ethnicity), health status and health risk behavior variables (diabetes, health status, smoking, heavy drinking, disability, life satisfaction, physical activity and fruit and vegetable intake). Results: Adults who had 3 or more vs. 1-2 supermarket/grocery stores within 3 miles of their residences had higher odds of being overweight/obese (AOR= 1.87, 95% CI 1.12- 3.13, p= 0.016). The adjusted odds of overweight/obesity were not significant for the distance to the closest food outlets, density of supermarket/grocery stores within half and 1 mile, and the density of fast-food restaurants and convenience stores within half-mile, 1 mile, and 3 miles buffer zones.Conclusion: The study results differ from the majority of previous studies¡¯ findings in the U.S th…
