- Adjusted models are controlled for sex, age at baseline, education, and cohort. T2D Type 2 diabetes, RR Relative risk, CI Confidence interval. RR are from modified Poisson regression models and reported per 1 standard deviation of walkability measures. RR over 1 indicate higher risk of T2D in areas with more transit stations and POI (indicators of better walkability). RR over 1 indicate higher risk of T2D in areas with higher impedance (indicator of poorer walkability)
- For prevalent T2D analysis (N = 16,008): standard deviation (SD) impedance: 291.3, POI: 4.8, transit stations: 4.4
- For incident T2D analysis (N = 12,105): SD impedance: 286.8, POI: 7.1, transit stations: 5.3
- For incident T2D non-movers (N = 5901) SD impedance = 284.6, POI: 6.7, transit stations: 4.9
- For incident T2D age ≥ 30 years at baseline (N = 11,416) SD impedance: 282.5, POI: 7.5, transit stations: 4.1
