  1. Multilevel logistic regression models were estimated after excluding individuals with missing values for the two explanatory variables. Noise variable were continuous and standardized (Lden indicator). These variables were estimated at the place of residence or in the residential neighborhood that corresponded to the 75th percentile of noise values in each 500 m radius street network buffer around the place of residence. Neighborhood income and education were coded as 4-category (low, mid-low, mid-high, and high) ordinal variables. Abbreviation: SES: socioeconomic status; B-N: between neighborhood.
