This longitudinal study analyzed 21 years of Indonesian Family Life Survey panel data (1993–2014) using satellite-derived geospatial measures of built-up land area to assess its association with adult BMI and overweight/obesity. Living in more built-up areas was associated with greater BMI and risk of being overweight or obese, though the estimated contribution was small but statistically significant.
This longitudinal study analyzed 21 years of panel data (1993–2014) from the Indonesian Family Life Survey, employing novel satellite-derived geospatial measures of built-up land area percentage to examine associations with adult BMI and overweight/obesity. Longitudinal regression models controlled for individual heterogeneity and initial BMI. Sex-stratified analyses were also conducted. Living in more built-up areas was associated with greater BMI and higher risk of being overweight or obese, though the effect sizes were small. A 6%-point average increase in built-up land area was estimated to account for around 1% of the rise in overweight and obesity. Stratified analyses showed overall patterns were very similar among men and women, though some pooled estimates lost significance likely due to smaller sample sizes. The study could not examine specific causal pathways due to a limited set of consistently measured variables.
