Increases in typical quantities consumed and alcohol-related problems during a decade of liberalizing alcohol policy

Objective:The aim of this study was to assess trends in drinking patterns and alcohol-related problems among age and gender groups in the context of a liberalized alcohol policy environment.Method:Eleven comparable general population alcohol surveys were conducted between 1990 and 2000 in Auckland, New Zealand, during which a substantial number of liberalizing alcohol policy changes occurred. Measurements included typical-occasion quantity and frequency of drinking in the last 12 months. Self-reported alcohol-related problems in the last 12 months were divided into two groups based on risk curve analysis: threshold problems (experienced only once a high level of consumption is reached) and nonthreshold problems (those exhibiting a dose-response relationship). Age groups were 14–19, 20–24, 25–39, and 40–65 years.Results:Significant increases in typical-occasion quantity were found for young men and young women ages 14–19 years and for women 20–24 and 40–65 years. The increase was most marked among those 14...
