Note: Tract-level measures were modeled separately. Models 1 and 2 were adjusted for the length of time in years that a participant reported living at the current neighborhood.
a
Quartile 1 reflects lowest deprivation while quartile 4 means the highest.
b
Additional adjustment for age, race/ethnicity, nativity, educational attainment, income level relative to the income threshold for poverty set by the federal government, employment status, and health insurance coverage.
