Abstract
AIMS: To assess (i) continuities in binge drinking across adulthood and (ii) the association between adolescent drinking level and adult binge drinking. DESIGN: Population-based prospective birth cohort. SETTING: England, Scotland and Wales. PARTICIPANTS: All births during one week in March 1958 (n = 8520 in analysis). MEASUREMENTS: Alcohol consumption reported at 16, 23, 33 and 42 years. Binge drinkers were identified by dividing number of units of alcohol consumed in the last week by usual drinking frequency, with limits of >/=10 units/occasion for men and >/=7 for women. FINDINGS: Four in five cohort members drank alcohol at least twice a month. Prevalences of binge drinking at 23, 33 and 42 years among men were 37%, 28% and 31% and among women 18%, 13% and 14%. Most binge drinkers in adulthood changed drinking status during this period. Nevertheless, binge drinking at age 23 increased the odds of binge drinking at 42 years: odds ratio (OR) 2.10 (95% CI 1.85, 2.39) for men; OR 1.56 (95% CI 1.29,1.89) for women. Women who rarely or never drank aged 16 were less likely than light drinkers (0-2 units/week) to binge drink as adults, OR at 23 years 0.65 (95% CI 0.55, 0.77). Men who were heavier drinkers (>/=7 units/week) at 16 years were more likely than light drinkers to binge drink throughout adulthood; at 42 years, OR 1.64 (95% CI 1.33, 2.08). CONCLUSIONS: Binge drinking is common in British men and women throughout adulthood with continuities between the 20s and 40s. Adolescent drinking has a modest although important association with adult binge drinking.
