CDC 1988b

Retrospective cohort, prevalence, population-based, telephone interview with screening medical examination at followup

2490 Vietnam-theater veterans, 1972 Vietnam-era veterans randomly selected from 7924 theater veterans and 7364 era veterans who had entered Army in 1965-1971

DIS-III-R, preceding month alcohol and drug abuse or dependence

Alcohol prevalence 13.7% vs 9.2%, OR 1.5, 95% CI 1.2-1.8; drugs prevalence 0.4% vs 0.5%, OR 0.9, 95% CI 0.4-2.0, NS

Age at enlistment, race, year of enlistment, enlistment status (volunteer vs draftee), score on general technical test, primary military occupational specialty

Low participation rate in control group; actual confidence interval not given

Boscarino 1995

Cross-sectional, used subset of VES

2490 Vietnam-theater veterans, 1972 Vietnam-era veterans randomly selected from 7924 theater veterans and 7364 era veterans who had entered Army in 1965-1971

DIS-III-R, preceding year substance abuse or dependence

Prevalence of alcohol or drug abuse or dependence for high war-zone stress, low war-zone stress, era, and civilians: Alcohol (men) lifetime 46%, 37%, 38%, 27%; 6 months 17%, 9%, 9%, 8%;

Drugs (men) lifetime 8%, 5%, 6%, 3%; 6 months 4%, 1%, 1%,

Data weighted to account for interview-level nonresponse and different probabilities of selection in civilian cohort; control for age, race or ethnicity, female veteran occupation

Response rates were greater than 83% for Vietnam-theatre veterans, 76% for Vietnam-era veterans and 70% for civilians. Because the use of self reported war zone stress exposure information was found to correspond well with military records, such
