Trans*female youth (TFY) carry a disproportionate burden of HIV. Few longitudinal studies have analyzed both proximal and upstream predictors of changes in HIV-related risk behaviors for TFY. The aim of the present analysis was to identify psychosocial predictors of changes in sexual risk behavior over time for TFY in the San Francisco Bay Area.
Data come from the SHINE cohort study conducted at the San Francisco Department of Public Health from 2012 to 2014 (n = 263). The relationship between hypothesized psychosocial factors and changes in engagement in condomless receptive anal intercourse over 12-month follow-up was modeled using generalized estimating equations, after adjusting for participant age, race/ethnicity, and education level.
TFY who were ever in a serious relationship since identifying as trans* [adjusted odds ratio (aOR) = 1.89, 95% confidence interval (CI): 1.16 to 3.08], those who reported recent crack/cocaine use (aOR = 2.01, 95% CI: 1.05 to 3.85), and those with a monthly income of more than $500 (aOR = 0.55, 95% CI: 0.35 to 0.85) had significantly higher odds of condomless receptive anal intercourse over the 12-month study period compared to TFY without these exposures. Those who reported high exposure to gender-based discrimination had increased adjusted odds of engagement in condomless receptive anal intercourse compared to those who had low exposure over the study period (aOR = 1.70, 95% CI: 1.10 to 2.63).
Both proximal and structural factors predicted increased engagement in sexual risk behavior among TFY. Results demonstrate the need for a multilevel approach to HIV prevention strategies for this population.
跨性别女性青少年(TFY)承受着不成比例的艾滋病毒负担。很少有纵向研究分析TFY艾滋病毒相关风险行为变化的近端和上游预测因素。本分析的目的是确定旧金山湾区TFY随时间变化的性风险行为的心理社会预测因素。
数据来自2012年至2014年在旧金山公共卫生部进行的SHINE队列研究(n = 263)。在调整参与者年龄、种族/族裔和教育水平后,使用广义估计方程对假设的心理社会因素与12个月随访期间无保护被动肛交参与度变化之间的关系进行建模。
自认定为跨性别者以来曾有过一段认真关系的TFY(调整后的优势比[aOR]=1.89,95%置信区间[CI]:1.16至3.08)、报告近期使用快克/可卡因的TFY(aOR = 2.01,95% CI:1.05至3.85)以及月收入超过500美元的TFY(aOR = 0.55,95% CI:0.35至0.85)在12个月的研究期间进行无保护被动肛交的几率显著高于未经历这些情况的TFY。与在研究期间遭受基于性别的歧视程度较低的TFY相比,报告遭受高度基于性别的歧视的TFY参与无保护被动肛交的调整后几率有所增加(aOR = 1.70,95% CI:1.10至2.63)。
近端因素和结构因素均预测TFY的性风险行为参与度会增加。结果表明需要针对该人群的艾滋病毒预防策略采取多层次方法。
