Long‐term effects of changes in Swedish alcohol policy: Can alcohol policies effective during adolescence impact consumption during adulthood?
Abstract AimsTo assess long‐term effects of alcohol policy in Sweden by estimating the differences between cohorts growing up during periods with liberal alcohol policies and a cohort growing up during a period with restrictive alcohol policy. DesignThe data come from repeated cross‐sectional surveys conducted in Sweden between 2002 and 2013, and were collected monthly using telephone interviews with a nationally representative sample. Cohorts were constructed by identifying periods when alcohol policy differed between being more liberal or more restrictive. The liberal‐period cohorts were merged into one and compared with the restrictive‐period cohort. SettingSweden. Participants127,480 adult Swedes born between 1951 and 1989. MeasurementsMonthly volume of alcohol consumption in liters of pure alcohol derived from a beverage‐specific graduated quantity‐frequency scale. FindingsRelative to the liberal‐period reference cohorts (who turned 15 between 1966 and 1977 or 1992 and 2004), the cohort that grew up during a period with restrictive alcohol policy (turning 15 between 1978 and 1991) was found to have lower alcohol consumption (coeff.=‐0.0386: confidence interval ‐0.0498 – ‐0.0274: p
