Subsidised housing and diabetes mortality: a retrospective cohort study of 10 million low-income adults in Brazil
Main finding · Diabetes mortalityResult — go to the resultHazard ratio 1.17 95% CI 1.05–1.31Authors' conclusion
Subsidised housing residents had a greater risk of diabetes mortality, particularly those living in low socioeconomic status municipalities. This finding suggests the need to intensify diabetes prevention and control actions and prompt treatment of the diabetes complications among subsidised housing residents, particularly among those living in low socioeconomic status municipalities.
