  1. *Excludes hospitalizations for complications of pregnancy, childbirth, and the puerperium (ICD-9-CM 630-676).
  2. ORs and associated confidence intervals from multiple logistic regression were adjusted for sex, age, education, marital status, race/ethnicity, pay grade, branch of service, occupation, BMI, smoking status, and problem drinking. CIs that exclude 1.00 were significant at the p < 0.05 level.
  3. Alcohol-related problems were defined by endorsement of any of the following that occurred more than once during the past year: (a) you drank alcohol even after a doctor suggested stopping due to health problems; (b) you drank alcohol, were high from alcohol, or were hung over while you were working, going to school, or taking care of children or other responsibilities; (c) you missed or were late for work, school, or other activities because you were drinking or hung over; (d) you had a problem getting along with people while you were drinking; (e) you drove a car after having several drinks or after drinking too much. No = none reported, Yes = one or more reported.
