We examined associations between sources of social influence (i.e. close friends, other underage people present) within specific settings with the number of drinks underage youth consumed.
Data were collected through a cross-sectional survey with 422 underage youth in California (14 to 19 years old) who reported past-6-month alcohol use. Participants were asked to think about the last time they drank alcohol in the past 6 months at: restaurants, bars/nightclubs, own home, another's home, outdoors, and fraternities/sororities. Outcomes were the number of whole drinks participants drank the last time in each setting. Independent measures were social characteristics of these drinking events including number of people <21 years old present, number of close friends present, number of <21 years old who consumed alcohol, and number of close friends who consumed alcohol. We also assessed socio-demographics and accounted for the overall exposure to each setting in the past 6 months.
Using negative binomial regression models, the number of close friends was positively associated with number of drinks consumed at restaurants, another's home, and outdoors. The number of close friends drinking was positively associated with the number of drinks at restaurants, own home, another's home, and outdoors. Number of people <21 years old was positively associated with number of drinks at own home, and number of people <21 years old who consumed alcohol was positivity associated with number of drinks consumed at restaurants, own home, another's home, and outdoors.
Results suggest that social influence from close friends and from other underage youth are context-specific.
我们研究了特定环境下的社会影响源（即亲密朋友、其他在场的未成年人）与未成年青少年饮酒量之间的关联。
通过对加利福尼亚州422名报告过去6个月饮酒情况的未成年青少年（14至19岁）进行横断面调查收集数据。参与者被要求回想过去6个月中他们在以下场所最后一次饮酒的情况：餐厅、酒吧/夜总会、自己家中、他人家中、户外以及兄弟会/姐妹会。结局指标是参与者在每个场所最后一次饮酒的整杯酒数量。独立变量是这些饮酒事件的社会特征，包括在场的21岁以下人员数量、亲密朋友数量、饮酒的21岁以下人员数量以及饮酒的亲密朋友数量。我们还评估了社会人口统计学特征，并考虑了过去6个月中在每个场所的总体暴露情况。
使用负二项回归模型，亲密朋友数量与在餐厅、他人家中和户外的饮酒量呈正相关。饮酒的亲密朋友数量与在餐厅、自己家中、他人家中和户外的饮酒量呈正相关。21岁以下人员数量与在自己家中的饮酒量呈正相关，饮酒的21岁以下人员数量与在餐厅、自己家中、他人家中和户外的饮酒量呈正相关。
结果表明，来自亲密朋友和其他未成年青少年的社会影响具有情境特异性。
