Figures estimate associations with elevated insulin resistance (HOMA-IR) greater than or equal to 3.31, elevated waist circumference greater than 88 cm, and elevated C-reactive protein greater or equal to 3.0 mg/L. Prevalence ratios estimated via binomial log regression with multiple imputations for missing covariates performed in PROC GENMOD, with repeated statement for neighborhood census tracts. Analysis excludes all diabetics (self-reported, use of diabetic medications, elevated fasting plasma glucose equal or greater than126 mg/dL, or hemoglobin A1C greater or equal to 6.5%), individuals with ≤400 kcal daily energy intake and individuals with HOMA-IR <0. Analyses are fully adjusted for listed covariates plus age, neighborhood stability, dietary intake (meeting USDA recommendations regarding the percentage of calories in carbohydrate and fat consumed, exceeding 15% of calories as protein, dietary fiber intake, and percentage of calories consumed as alcohol), scaled family household income, and less than high school educational attainment. Reference categories: Lives in most advantaged neighborhoods, does not perceives neighborhood as unsafe, former or never smoker. Active Living Index modeled as a continuous variable.
