Objective Evidence demonstrates sexual orientation disparities in physical and sexual victimization and alcohol misuse and consequences among female youth; however, most extant research has used variable-centered approaches. The current study used latent class analysis (LCA), a person-centered approach, to: (1) model female youths' physical and sexual victimization; (2) examine sexual orientation disparities in physical and sexual victimization latent class membership; (3) and use physical and sexual victimization latent class membership to predict female youths' engagement in alcohol misuse and related consequences. Method Participants were 7,185 youth assigned female sex at birth (77.0% heterosexual, 12.8% bisexual, 2.3% gay or lesbian; 46.8% racial minority) in grades 9 - 12 who completed the 2017 Youth Risk Behavior Survey - a school-based, cross-sectional survey. Results LCA uncovered four classes: (1) "Poly-Victimization Class," (2) "No Victimization Class," (3) "Past-Year Sexual Victimization Class," and (4) "Lifetime Rape Class." Sexual orientation emerged as a significant predictor of class membership. Latent classes 3 and 4 were uniquely associated with alcohol misuse and consequences (i.e., binge drinking, riding with a drinking driver, and drinking and driving) among female youth. Conclusions Our findings help to elucidate the patterns of physical and sexual victimization regarding timeline, tactic used, and context among female youth; sexual orientation disparities in latent class membership; and alcohol misuse correlates of class membership. Prevention efforts aimed at reducing physical and sexual victimization may ultimately reduce female youths' risk of binge drinking, riding with drinking drivers, and drinking and driving.

性少数和异性恋女性青年的身体和性受害班级成员资格和酒精滥用及其后果。

客观证据表明，女性青年在身体和性受害、酗酒和后果方面存在性取向差异；然而，大多数现存的研究都使用了以变量为中心的方法。目前的研究使用以人为中心的潜在类别分析（LCA）来：（1）模拟女性青年的身体和性受害；(2) 检查身体和性受害潜在阶级成员的性取向差异；(3) 并使用身体和性受害潜类成员来预测女性青年参与酒精滥用和相关后果。方法 参与者是 7,185 名出生时指定为女性的青少年（77.0% 异性恋，12.8% 双性恋，2.3% 男同性恋或女同性恋；46. 8% 少数族裔）在 9 至 12 年级完成了 2017 年青年风险行为调查 - 一项基于学校的横断面调查。结果 LCA 发现了四个类别：（1）“多重受害类别”，（2）“无受害类别”，（3）“过去一年的性受害类别”和（4）“终身强奸类别”。性取向成为阶级成员的重要预测因素。潜伏等级 3 和 4 与女性青年的酒精滥用和后果（即狂饮、与饮酒司机一起骑行以及酒后驾驶）具有独特的相关性。结论 我们的研究结果有助于阐明女性青年在时间线、使用的策略和背景方面的身体和性受害模式；潜在阶级成员的性取向差异；和酒精滥用与班级成员相关。旨在减少身体和性伤害的预防措施最终可能会降低女性青少年暴饮暴食、与酒驾一起骑行以及酒后驾车的风险。
