Studies of peer crowds show promise for enhancing public health promotion and practice through targeting. Distinct images, role models, and social norms likely influence health behaviors of different peer crowds within health disparity groups. We describe peer crowds identified by Black young people and determine whether identification with them is associated with smoking. Data from Black young people aged 13 to 20 years in Richmond, Virginia, were collected via interview and online survey (N = 583). We identified the number and type of peer crowds using principal components analysis; associations with smoking were analyzed using Pearson chi-square tests and logistic regression. Three peer crowds were identified--"preppy," "mainstream," and "hip hop." Youth who identify with the hip hop peer crowd were more likely to smoke and have friends who smoke and less likely to hold antitobacco attitudes than those identifying with preppy or mainstream crowds. Identifying with the hip hop crowd significantly increased the odds of smoking, controlling for demographic factors (odds ratio = 1.97; 95% confidence interval = 1.03-3.76). Tobacco prevention efforts for Black youth and young adults should prioritize the hip hop crowd. Crowd identity measures can aid in targeting public health campaigns to effectively engage those at highest risk.
对同龄人群体的研究显示，通过针对性干预有望加强公共卫生促进工作及实践。不同的形象、榜样和社会规范可能会影响健康差距群体中不同同龄人群体的健康行为。我们描述了由黑人年轻人所识别出的同龄人群体，并确定与这些群体的认同是否与吸烟有关。通过访谈和在线调查收集了来自弗吉尼亚州里士满市13至20岁黑人年轻人的数据（N = 583）。我们使用主成分分析确定同龄人群体的数量和类型；使用Pearson卡方检验和逻辑回归分析与吸烟的关联。识别出了三个同龄人群体——“预科生型”、“主流型”和“嘻哈型”。与“预科生型”或“主流型”群体相比，认同“嘻哈型”同龄人群体的年轻人更有可能吸烟且其朋友也吸烟，且持有反烟草态度的可能性更小。在控制人口统计学因素后，认同“嘻哈型”群体显著增加了吸烟几率（优势比 = 1.97；95%置信区间 = 1.03 - 3.76）。针对黑人青少年和年轻人的烟草预防工作应将“嘻哈型”群体作为重点。群体认同指标有助于使公共卫生运动更具针对性，从而有效吸引风险最高的人群。
