To examine mechanisms underlying the development of sexual health risk behaviors in sexual minority girls (SMGs) and its association with sexual victimization.
Data were drawn from the Project on Human Development in Chicago Neighborhoods cohorts, aged 15 and 18 years (N = 391; 54 SMGs).
Sexual minority girls reported more sexual victimization and steeper positive trajectories of substance misuse over time than heterosexual girls. Growth in alcohol use during adolescence mediated the link between SMG status and past year number of partners, whereas growth in marijuana use mediated the link between SMG status and self-reported sexually transmitted diseases (STDs). Adding unwanted sexual experiences to the models resulted in a reduction of significance in the direct or indirect effects from SMG status on the sexual health outcomes. Unwanted sexual experiences emerged as a robust predictor directly and indirectly related to past-year number of partners via growth in alcohol use. Unwanted sexual experiences also directly predicted STD history.
The increased risk of SMGs for alcohol and marijuana during adolescence, higher rates of sexual partners, and STD diagnosis may also be linked to their significant risk for sexual victimization. Findings highlight the importance of preventive interventions targeting victimization of SMGs.
探讨性少数群体女孩（SMG）性健康风险行为发展的潜在机制及其与性侵害的关联。
数据取自芝加哥邻里人类发展项目队列，年龄为15岁和18岁（N = 391；54名SMG）。
与异性恋女孩相比，性少数群体女孩报告的性侵害更多，且随着时间推移物质滥用的积极轨迹更陡峭。青春期饮酒量的增加介导了SMG身份与过去一年性伴侣数量之间的联系，而大麻使用量的增加介导了SMG身份与自我报告的性传播疾病（STD）之间的联系。在模型中加入 unwanted sexual experiences后，SMG身份对性健康结果的直接或间接影响的显著性降低。 unwanted sexual experiences成为一个强有力的预测因素，通过饮酒量的增加直接和间接地与过去一年的性伴侣数量相关。 unwanted sexual experiences还直接预测了性传播疾病史。
性少数群体女孩在青春期酒精和大麻风险增加、性伴侣率更高以及性传播疾病诊断率更高，也可能与其遭受性侵害的重大风险有关。研究结果凸显了针对预防性少数群体女孩遭受侵害的干预措施的重要性。
