Abstract
PURPOSE: To estimate the prevalence of alcohol use at the age of 10-11 years and document variation by early sociodemographic and concurrent alcohol-specific risk factors. METHODS: The Millennium Cohort Study is a prospective, nationally representative study of live births in the United Kingdom across 12 months. A random sample of electoral wards was stratified to adequately represent U.K. countries, economically deprived areas, and areas with high concentrations of Asian and Black British families. A total of 12,305 child-mother pairs provided self-report data at 9 months (mother's marital status, age, education, occupational level; child gender, ethnicity, country) and age 10-11 years (adolescent alcohol use and attitudes). RESULTS: After adjusting for attrition and sampling design, 13.4% of 10- to 11-year-olds had had an alcoholic drink (more than few sips), 1.2% had felt drunk, and .6% had five or more drinks at a time. Odds of ever drinking were higher among boys (1.47, 95% confidence interval, 1.29-1.68) and lower among early adolescents who were Asian British (vs. white; .09, .05-.17) or Black British (.42, .29-.62). Beyond sociodemographic differences, more positive attitudes about alcohol were associated with greater odds of drinking (1.70, 1.51-1.91), feeling drunk (2.96, 2.07-4.24), and having five or more drinks (4.20, 2.66-6.61). CONCLUSIONS: Alcohol use in the last year of primary school was identified but not common. Its use varied by sociodemographic groups; early adolescents with more positive alcohol attitudes had especially high risks of early alcohol initiation. Results support calls for increased surveillance and screening for very early drinking.
