Neighborhood-level analysis on the impact of accessibility to fast food and open green spaces on the prevalence of obesity
American Journal of Medicine Oct 21, 2019
Mylona EK, et al. – Researchers assesed how accessibility to fast food restaurants and green spaces are linked to obesity via analyzing the geocoded BMI values of 20,927 individuals. They used spatial analysis and logistic regression to examine the association of obesity at the individual level and obesity hot and cold spots with the accessibility to fast food restaurants and green space areas. The age-adjusted prevalence of obesity was 33%. Obese individuals demonstrated a lower likelihood of residing in neighborhoods with the highest accessibility to green space areas vs neighborhoods with low accessibility. Obese individuals were more likely to live in neighborhoods with medium or high accessibility to fast food restaurants. Looking at obesity clustering, the researchers found that hot spots were 18% and 21% less likely to be located in neighborhoods with medium and high accessibility to green space areas, respectively. By contrast, hot spots were 1.65 and 4.81 times more likely to be located in neighborhoods with medium and high accessibility to fast food restaurants, respectively. Overall, accessibility to fast food restaurants was positively linked to the presence of obesity hot spots, while access to green space areas were linked to decreased neighborhood obesity rates.
