Abstract: Abstract Diabetes is a serious public health issue in developing countries, particularly in urban regions. Heat exposure, measured by residential area land surface temperature (LST), may contribute to the risk of diabetes among urban dwellers due to rapid urbanisation and climate change. This might be useful to predict urban diabetes risk. However, this relationship has not been thoroughly assessed in developing countries. Additionally, residential area greenery may mitigate the detrimental effects of high LST. This study examines the association between residential area LST and diabetes among adults (aged ≥ 18 years) in urban regions of Bangladesh and whether residential area greenness modifies the association. Study data were derived from the latest Bangladesh Demographic and Health Survey 2017–2018, and survey cluster-level LST and enhanced vegetation index (i.e. greenness) were used to define residential area-level environmental features. A binary logistic regression was used to estimate the association, and stratified analysis was performed to examine the effect modification role of greenness. Living in areas with a greater LST increased the odds of having diabetes (AOR 1.23, 95% CI 1.01–1.50, p value = 0.035), whereas residing in areas with greater greenness decreased the odds of having diabetes (AOR 0.07, 95% CI 0.01–0.88, p value = 0.039). The effect of LST on diabetes was more pronounced in adults who lived in urban areas with less greenery (AOR 1.31, 95% CI 1.01–1.71, p value = 0.048). This evidence has significant ramifications for local communities, and the improvement of green infrastructure may reduce heat exposure-related health risks in the context of climate change and urbanisation.
