The aim of this study was to examine whether the drinking habits of parents, siblings, and friends were related to regular drinking in adolescents and young adults, cross-sectionally as well as longitudinally.
Data of 12-30-year-old twins from the Netherlands Twin Register were analysed. Information on regular drinking was collected in 1993, 1995, and 2000. Logistic regression analyses were conducted on cross-sectional data of 1993 (N=3760), short-term longitudinal data of 1993-95 (N=2919), and the long-term longitudinal data of 1993-2000 (N=1779).
Results show that age, sex, and one's own previous drinking habits were important predictors of later-life regular drinking. Drinking habits of parents showed small but persistent positive associations. Alcohol use of the co-twin was strongly related to alcohol use of the participants, especially in the cross-sectional analyses, while alcohol use of additional siblings other than the co-twin was relatively unimportant. Cross-sectionally, friends' alcohol use showed a high association with regular drinking, but this association decreased over time.
Cross-sectional analyses showed that a substantial part (29%) of the variance in regular drinking habits of adolescents and young adults was explained by the drinking habits of family members and friends, in particular, by drinking of co-twins and friends. But, over time, drinking by family members and friends could only explain a relatively small part (4-5%) of the variance in adolescents' and young adults' alcohol use.
本研究旨在横断面及纵向考察父母、兄弟姐妹和朋友的饮酒习惯与青少年及青年定期饮酒之间是否存在关联。
对来自荷兰双胞胎登记处的12至30岁双胞胎的数据进行分析。1993年、1995年和2000年收集了关于定期饮酒的信息。对1993年的横断面数据（N = 3760）、1993 - 1995年的短期纵向数据（N = 2919）以及1993 - 2000年的长期纵向数据（N = 1779）进行逻辑回归分析。
结果表明，年龄、性别以及个人先前的饮酒习惯是后期定期饮酒的重要预测因素。父母的饮酒习惯显示出虽小但持续的正相关。同卵双胞胎的饮酒情况与参与者的饮酒情况密切相关，尤其是在横断面分析中，而异卵双胞胎之外的其他兄弟姐妹的饮酒情况相对不太重要。横断面分析中，朋友的饮酒情况与定期饮酒高度相关，但这种关联会随着时间减弱。
横断面分析表明，青少年及青年定期饮酒习惯差异的很大一部分（29%）可由家庭成员和朋友的饮酒习惯来解释，特别是同卵双胞胎和朋友的饮酒情况。但是，随着时间推移，家庭成员和朋友的饮酒情况只能解释青少年及青年饮酒差异中相对较小的一部分（4 - 5%）。
