Aims: Alcohol-attributable harm remains high worldwide, and alcohol use among adolescents is particularly concerning. The purpose of this study is to determine the effect of national alcohol control policies on adolescent alcohol use in low-, middle- and high-income countries and improve on previous cross-national attempts to estimate the impact of alcohol policy on this population.
Methods: Data on adolescent (n = 277,110) alcohol consumption from 84 countries were pooled from the Global School-based Health Survey and the European School Survey Project on Alcohol and Other Drugs. Alcohol use measures included lifetime alcohol use, current (past 30 days) alcohol use and current (past 30 days) binge drinking. Information on national alcohol control policies was obtained from the World Health Organization's Global Information System on Alcohol and Health and scored for effectiveness. Main effects were estimated using two-level, random intercept hierarchical linear models, and the models were adjusted for sex and age of the participants, and pattern of drinking score, gross domestic product based on purchasing power parity and study at the country level.
Results: Availability (OR [95% CI] = 0.991 [0.983, 0.999]), marketing (OR [95% CI] = 0.994 [0.988, 1.000]) and pricing (OR [95% CI] = 0.955 [0.918, 0.993]) policies were inversely associated with lifetime drinking status. Pricing policies were also inversely associated with current binge drinking status among current drinkers (OR [95% CI] = 0.939 [0.894, 0.986]). There were no associations between the included alcohol policies and current drinking status.
Conclusions: Strong availability, marketing and pricing policies can significantly and practically impact adolescent alcohol consumption.
