Chunk #19 — Materials and Methods — Data Analysis — Associations between alcohol use initiation, childhood trauma, SES, and neighborhood factors by race
Prevalence of alcohol use initiation, exposure to childhood trauma (i.e., ever experienced a traumatic event) indicators of low SES, age at first drink, and scores on neighborhood measures were calculated by race, with sample weights applied to mean and prevalence estimates to account for oversampling of families living in low-income neighborhoods. Tests for racial differences were conducted using binomial logistic regression analyses for dichotomous variables and independent sample t-tests for continuous variables. Univariate logistic regression analyses were also conducted to estimate associations of SES indicators and neighborhood factors with childhood trauma exposure and alcohol use initiation. Data sets were constructed and preliminary analyses conducted using SAS [37].
