Outline
To examine the effects of the residential built environment on obesity among adults, and to provide evidence to inform built environment optimization for the prevention and control of overweight and obesity.
This cross-sectional study included individuals who underwent health examinations at the Health Management Center of Renmin Hospital of Wuhan University between May and August 2023. Of 1 672 examinees, 1 349 participants who met the inclusion criteria and had complete data were included in the analysis. Information on long-term residential address, residential floor, sex, age, and body mass index (BMI) was collected, and spatial analysis methods were applied to quantify environmental characteristics surrounding participants’ residential locations. Least Trimmed Squares (LTS) regression and logistic regression models were used to assess the associations between environmental factors and BMI, as well as overweight/obesity status. Generalized linear mixed models (GLMMs) were employed to examine the relationship between residential floor level and the likelihood of overweight/obesity.
Among the 1 349 participants, the prevalence of overweight and obesity was 36.4% and 11.0%, respectively. Higher accessibility to transportation facilities (coef=0.324, P<0.001) and dining facilities (coef=0.233, P=0.006) were associated with increased BMI. Greater accessibility to transportation facilities (OR=1.141, 95% CI:1.000-1.302) and exercise facilities (OR=1.177, 95% CI: 1.017-1.362) were associated with a higher risk of overweight/obesity. As residential floor level increased, the probability of overweight/obesity first increased and then decreased, reaching a peak at around the 14th floor.
BMI and the likelihood of overweight/obesity were associated with multiple environmental factors. Residential floor level affected the probability of overweight/obesity, which may be related to stair-related physical activity and the indirect influence of individual characteristics across different floor levels.
