Summary
This summary is machine-generated.Higher park density widens socioeconomic inequalities in type 2 diabetes prevalence, contrary to the equigenic hypothesis. This study reveals that areas with more parks show greater disparities in diabetes rates between socioeconomic groups.
Area Of Science
- Environmental Health
- Public Health
- Epidemiology
Background
- Conflicting evidence exists regarding the impact of urban green space density on socioeconomic inequalities in type 2 diabetes.
- The equigenic hypothesis suggests green spaces may reduce these disparities.
Purpose Of The Study
- To investigate if park density modifies socioeconomic inequalities in diabetes prevalence.
- To test the equigenic hypothesis in the context of urban environments.
Main Methods
- Population-wide cross-sectional study of 1,305,050 adults in Madrid, Spain.
- Utilized georeferenced electronic health records and census-tract data on socioeconomic status (SES) and park density.
- Employed robust Poisson regression models with interaction terms to analyze diabetes prevalence and SES inequalities, stratified by gender.
Main Results
- Diabetes prevalence was significantly higher in low SES compared to high SES areas (RII: 2.90 for men, 4.50 for women).
- Socioeconomic inequalities in diabetes prevalence were wider in areas with higher park density for both genders.
- A significant interaction between park density and SES inequalities was observed for women (p=0.008).
Conclusions
- An inverse association between SES and diabetes prevalence exists, with inequalities exacerbated by higher park density.
- Findings challenge the equigenic hypothesis, indicating urban green space may not mitigate diabetes disparities.
- Further research is needed to understand the mechanisms driving these contextual factors.
