About 43 percent of U.S. adults--76 million people--have been exposed to alcoholism in the family: they grew up with or married an alcoholic or a problem drinker or had a blood relative who was ever an alcoholic or problem drinker. Exposure was higher among women (46.2 percent) than among men (38.9 percent) and declined with age. Exposure to alcoholism in the family was strongly related to marital status, independent of age: 55.5 percent of separated or divorced adults had been exposed to alcoholism in some family member, compared with 43.5 percent of married, 38.5 percent of never married, and 35.5 percent of widowed persons. Nearly 38 percent of separated or divorced women had been married to an alcoholic, but only about 12 percent of currently married women were married to an alcoholic. These findings are highlights of an analysis of the 1988 National Health Interview Survey on Alcohol that is presented in this report.
