Stratified analyses between income and NDVI (A) and LAI (B) in 100 m around the home, stratified by participant characteristics. Notes: N = 636. Effect estimates of linear regression models adjusted for participants’ age, gender, race, income, education, mother’s education, employment status, and traffic density with 95% confidence intervals (CI) of the middle (circles) and high (squares) income groups. Reference group was the low-income group (annual household income < 20,000 USD). A. 100 m NDVI and Income, B. 100 m LAI and income. NDVI and LAI stratifications represent associations between income and greenness within 100 m stratified by high and low greenness values within a 500 m radius.
