The association between community-aggregated levels of peer and individual risk and protective factors and prevalence of adolescent substance use was examined in repeated cross-sectional data among youth in 41 communities ranging in population from 1,578 to 106,221. The association between community levels of these peer and individual risk and protective factors in 2000 and substance use 2 years later was examined by using within-cohort analyses (e.g., sixth grade in 2000 predicting eighth grade in 2002) and cross-cohort analyses (e.g., sixth grade in 2000 predicting sixth grade in 2002). In both within- and across-cohort analyses, community-aggregated levels of peer and individual risk and protective factors predicted the prevalence of adolescent substance use 2 years later, suggesting that focusing on elevated peer and individual risk factors and depressed peer and individual protective factors at the community level to guide the selection of preventive interventions may be a viable strategy for community efforts to prevent adolescent substance use community wide.
在41个社区（人口从1578人到106221人不等）的青少年重复横断面数据中，研究了社区层面同伴和个体风险及保护因素的聚集水平与青少年物质使用患病率之间的关联。通过队列内分析（例如，2000年六年级预测2002年八年级）和队列间分析（例如，2000年六年级预测2002年六年级），研究了2000年这些同伴和个体风险及保护因素的社区水平与两年后物质使用之间的关联。在队列内和队列间分析中，同伴和个体风险及保护因素的社区聚集水平都预测了两年后青少年物质使用的患病率，这表明关注社区层面升高的同伴和个体风险因素以及降低的同伴和个体保护因素，以指导预防性干预措施的选择，可能是社区在全社区预防青少年物质使用工作中的一个可行策略。
