title: Gender differences in the risk of alcohol dependence: United States, 1992.
abstract: Data from a representative sample of US adults revealed that 24% of male life-time drinkers and 15% of female life-time drinkers met the DSM-IV criteria for life-time alcohol dependence, i.e. dependence during the year preceding interview or in any 12-month period prior to that year. The median interval from first drink to onset of dependence was 3.6 years for men and 3.0 years for women. After using survival techniques to adjust for potential gender differences in the exposure to risk of developing alcohol dependence, the cumulative conditional probability of having experienced onset of dependence was 35.1% for men and 24.6% for women. The conditional probability of onset of dependence was equal for men and women in the first year after initiation of drinking, about 30% higher for men in the period 1-4 years after the first drink, and about 45% higher for men thereafter. After using proportional hazards models to adjust for the effects of age cohort, race and ethnicity, family history of alcoholism and age at first drink, these period-specific risk ratios remained virtually unchanged. Including a measure of average daily ethanol intake during periods of heaviest consumption rendered most of the gender differences statistically insignificant, revealing a slight excess risk of female dependence within the first year after initiation of drinking among the heaviest drinkers and leaving an excess male risk of dependence mostly among individuals with average daily intakes of less than one ounce of ethanol. The results suggest that different frequencies of binge drinking might help to account for these remaining gender differences and that men's and women's relative risks of developing alcohol dependence may vary as a function of life cycle stage, with men's excess risk greatest in the college/young adult years.
