Association Between Rental Assistance Programs and Undiagnosed Diabetes Among U.S

Background Rental assistance programs have been linked to better housing quality, stability, healthcare access, and reduced likelihood of uncontrolled diabetes. However, its direct association with diabetes screening is uncertain. Objective To determine whether federal rental assistance programs are associated with lower odds of undiagnosed diabetes. Design We used a quasi-experimental approach, comparing outcomes among adults receiving rental assistance to those who entered assisted housing within 2 years after their health data were collected. We test the a priori hypothesis that rental assistance will be associated with decreased odds of undiagnosed diabetes. Participants Participants in the National Health and Nutrition Examination Survey 1999–2018 who received rental assistance and who had diabetes. Intervention Current rental assistance participation, including specific housing programs. Main Measures Undiagnosed diabetes based on having hemoglobin A1c ≥ 6.5% but answering no to the survey question of being diagnosed with diabetes. Key Results Among 435 eligible adults (median age 54.5 years, female 68.5%, non-Hispanic white 32.5%), 80.7% were receiving rental assistance programs at the time of the interview, and 19.3% went on to receive rental assistance within 2 years. The rates of undiagnosed diabetes were 15.0% and 25.3% among those receiving rental assistance programs vs. those in the future assistance group ( p -value = 0.07). In an adjusted logistic regression model, adults receiving rental assistance had lower odds of undiagnosed diabetes (OR 0.52, 95% CI 0.28–0.94) than those in future assistance groups. Sex, race and ethnic group, educational level, and poverty ratio were not significantly associated with having undiagnosed diabetes, but individuals aged 45–64 years had significantly lower odds of undiagnosed diabetes (OR 0.21, 95% CI 0.08–0.53) compared with those aged 18–44. Conclusions Rental assistance was linked to lower odds of undiagnosed diabetes, suggesting that affordable housing programs can aid in early recognition and diagnosis, which may improve long-term outcomes.
