This study aims to identify peers and social network characteristics associated with drinking occasions through early adolescence.
The study sample of 1808 middle school students (aged 13-15 years) in northern Taiwan was collected via a two-wave longitudinal study of the Alcohol-Related Experiences among Children (AREC). Data concerning individual sociodemographics, family characteristics, peer influence, and alcohol drinking behaviors were collected via web-based self-administered questionnaire. Building upon the maximum of five friends nominated by young respondents at 7th grade, class-based social network was first constructed via the UCINET and Pajek; the network position (i.e., member, bridge, and isolate) for each student was subsequently ascertained. Complex surveys analyses and negative binominal regression models were used to evaluate concurrent and prospective relationship estimates.
Effects of peers and social network were found to operate differentially by childhood alcohol experience. For the alcohol naïve youngsters, receiving higher peer's nomination at baseline was linked with subsequent increased drinking occasions (adjusted Incidence Rate Ratio [aIRR]=1.06; 95% CI=1.01-1.10), whereas having peers against alcohol drinking may reduce drinking occasions at 9th grade (aIRR=0.59; 95% CI=0.41-0.87). For the alcohol experienced youngsters, having parental alcohol offer, drinking peers, and attending classes of higher drinking norms may increase future drinking occasions by 90%, 80% and 44%, respectively.
Our results demonstrated that parental alcohol offer, peer norms, and social network may affect adolescent drinking occasions differentially depending on childhood drinking experience. The findings have implications for the interventions to reduce alcohol consumption in underage population.
本研究旨在确定与青春期早期饮酒场合相关的同龄人及社交网络特征。
通过对台湾北部1808名中学生（13 - 15岁）进行两波次的儿童酒精相关经历纵向研究（AREC）来收集研究样本。通过基于网络的自填问卷收集有关个人社会人口统计学、家庭特征、同伴影响和饮酒行为的数据。基于七年级年轻受访者提名的最多五个朋友，首先通过UCINET和Pajek构建基于班级的社交网络；随后确定每个学生在网络中的位置（即成员、桥梁和孤立者）。使用复杂调查分析和负二项回归模型来评估并发和前瞻性关系估计。
发现同伴和社交网络的影响因童年饮酒经历而异。对于从未饮酒的青少年，基线时获得较高的同伴提名与随后饮酒场合增加有关（调整后的发病率比[aIRR]=1.06；95%置信区间=1.01 - 1.10），而有反对饮酒的同伴可能会减少九年级时的饮酒场合（aIRR=0.59；95%置信区间=0.41 - 0.87）。对于有饮酒经历的青少年，父母提供酒精、有饮酒的同伴以及参加饮酒规范较高的班级，可能分别使未来饮酒场合增加90%、80%和44%。
我们的结果表明，父母提供酒精、同伴规范和社交网络可能会根据童年饮酒经历对青少年饮酒场合产生不同影响。这些发现对减少未成年人群体酒精消费的干预措施具有启示意义。
