Prevalence (%)	20.7	25.8	20.7
Odds ratio	1.00	1.49 (1.10–2.01)	1.07 (0.90–1.28)

Odds ratio	2.20 (1.43–3.40)a	1.47 (1.05–2.05)	1.92 (1.36–2.70)a,b
Current drinker
Prevalence (%)	25.0	26.7	21.5
Odds ratio	1.32 (1.09–1.59)	1.38 (1.05–1.82)	1.10 (0.93–1.27)

Data reported as odds ratios (95% confidence intervals), adjusted for age, daily total caloric intake, and physical activity.

^aP value was considered significant using Bonferroni correction for multiple comparisons.

^bInteraction = 1.67 (1.24–2.25), P = 0.002; reference was nondrinker and nonsmoker.
