Since 2000, adolescent alcohol use has declined substantially in many high-income countries, particularly in Northern Europe. This study examined whether birth cohorts in Norway who experienced different levels of alcohol consumption in mid-adolescence differed in drinking behaviour when they reached young adulthood. We analysed data from annual population surveys in Norway (2012-2021). The analytic sample comprised data from respondents aged 20-29 years (N = 5266), and we applied four birth cohorts (i.e., 1983-1987, 1988-1992, 1993-1996 and 1997-2001). We applied age categories with two- and five-year intervals and tested whether drinking frequency, heavy episodic drinking (HED) and usual number of drinks per drinking occasion during the past 12 months differed by birth cohort in age-specific strata. Possible cohort differences within age groups were tested using Pearson's Chi square. There were no statistically significant differences between cohorts with respect to drinking frequency or HED frequency. However, the youngest cohort had fewer drinks per occasion when in their early 20s compared to older cohorts. This study showed that birth cohorts who differed substantially in levels of alcohol consumption in mid-adolescence, only to a little extent differed in drinking behaviour in young adulthood.
自 2000 年以来，许多高收入国家的青少年饮酒量大幅下降，尤其是在北欧国家。本研究旨在探讨挪威青少年在中期经历不同程度的饮酒量后，在成年早期的饮酒行为是否存在差异。我们分析了挪威年度人口调查的数据（2012-2021 年）。分析样本包括年龄在 20-29 岁的受访者数据（N=5266），并应用了四个出生队列（即 1983-1987 年、1988-1992 年、1993-1996 年和 1997-2001 年）。我们应用了两年和五年的年龄分类，并检验了在过去 12 个月中，不同出生队列在特定年龄组的饮酒频率、重度饮酒（HED）和每次饮酒的平均饮酒量是否存在差异。使用 Pearson Chi 平方检验了各年龄组内的可能队列差异。在饮酒频率或 HED 频率方面，各队列之间没有统计学上的显著差异。然而，最年轻的队列在 20 岁出头时每次饮酒的量比其他较年长的队列少。本研究表明，在中期经历过大量饮酒的出生队列，在成年早期的饮酒行为上只存在很小程度的差异。
