Implementation and Evaluation of a Multi-Level Positive Youth Development Interv

拟议的乔治华盛顿大学公共卫生和HeaKh服务学院（GWU SPHHS） P-20探索中心的总体研究目的是建立在我们与拉丁裔移民社区合作伙伴的现有合作基础上，以解决药物滥用和共同发生的健康问题的复杂因素，包括家庭/伴侣暴力，性风险和青少年暴力。拉丁裔移民社区尤其经历了这些同时发生的情况的不成比例的比例——一些研究表明，拉丁裔中学生和青少年报告的药物使用率是所有种族/民族群体中最高的，并且药物滥用和其他风险同时发生。促成因素根植于复杂的社会决定因素，这在华盛顿都市区众多移民群体中是独一无二的，部分源于内战的历史遗产和该地区大多数中美洲拉丁裔人口所经历的艰难移民，导致长期边缘化和随之而来的风险社会生态的产生。此外，这组差异条件的存在对人口解决其他差异（如肥胖/糖尿病）的能力产生了影响（因为，例如，当上述条件普遍存在时，在社区中从事体育活动会更加困难）。

The overall research purpose of the proposed George Washington University School of Public Health and HeaKh Services (GWU SPHHS) P-20 Exploratory Center is to build on our existing collaboration with Latino immigrant community partners to address a complex of contributing factors for substance abuse and cooccurring health issues, including family/partner violence, sexual risk, and youth violence. The Latino immigrant community in particular has experienced disproportionate rates of these co-occurring conditions -with some studies showing Latino middle school students and youth reporting the highest substance use rates of any racial/ethnic group, and a co-occurrence of substance abuse and other risk. Contributing factors are rooted in a complex of social determinants unique among the numerous immigrant groups in the DC metro area, stemming in part from the historical legacy of civil war and difficult migration experienced by the majority Central American Latino population in this area, resulting in long-term marginalization and the concomitant creation of a social ecology of risk. Moreover, the presence of this cluster of disparity conditions has impacts on the ability of the population to address other disparities such as obesity/diabetes (because, for example, engaging in physical activity is more difficult in communities when the above conditions are prevalent).
