Socioeconomic status (SES) categories high and low were defined based on income (≤$25,000, >$25,000), education (“≤grade 12 or GED”, “some college or college graduate”) and employment (“out-of/unable-to work”, “occupation with some income”). (See online Version Only -Supplementary Table 3). High SES: income >$25,000 or, if income was missing, “some college or college graduate” AND “occupation with some income”. Low SES: income ≤$25,000, or, if income was missing, low education and/or “out-of/unable-to work”; 1 subject missing income and education with “occupation with some income” was classified as low SES.
Drinking habits: Non-drinker/Mild: past drinking ≤2 drinks/day or current drinking ≤2 drinks/day for 1–15 days/month; Moderate: past drinking 3 to <5 drinks/day or current drinking ≤2 drinks/day for 16–30 days/month or ≥3 drinks/day for 1–15 days/month; Heavy: past drinking 5 or more drinks/day or current drinking ≥3 drinks /day for 16–30 days/month.
