Alcohol and drug use by women is related to high-risk sexual practices and protective behaviors.
To determine sexual risk and protective behaviors using information about women's drug use immediately before or during sex.
Latent class analysis using PROC LCA in SAS software was used to determine classes of women using both past 30-day drug use and before or during sex. Participants were recruited from a community-based research site located in a low socio-economic area of Los Angeles County and completed the Risk Behavior Assessment, which elicits information on drug and sex risk behaviors.
The Risk Behavior Assessment and HIV and sexually transmitted infections testing was obtained on 812 women. Five distinct groups were identified by PROC LCA: An Abstinent group comprised of 26% of participants; an Alcohol and Marijuana group (16%); an Amphetamine group (11%); a No Sex-with-Alcohol group (37%); and a Poly Drug group (11%). Multinomial logistic regression revealed that sexual behaviors and condom use were different across the five groups: The Alcohol and Marijuana group had a higher odds of vaginal intercourse, while the No Sex-with-Alcohol group was most likely to use condoms for vaginal intercourse. The Poly Drug group had the highest risk for anal intercourse while the Amphetamine and Poly Drug groups had high proportions of women with injection-drug using and men-who-have-sex-with-men sexual partners.
Identifying women based on drug use immediately before or during sex can help providers understand prevention and risk-reduction practices and interventions for drug-using women.
女性的酒精和药物使用与高危性行为和保护行为有关。
确定女性在性行为前后使用药物时的性风险和保护行为。
使用 SAS 软件中的 PROC LCA 进行潜在类别分析，以确定在过去 30 天内使用药物和性行为前后使用药物的女性类别。参与者是从位于洛杉矶县社会经济水平较低地区的一个社区研究点招募的，他们完成了风险行为评估，该评估收集了关于药物和性风险行为的信息。
对 812 名女性进行了风险行为评估和 HIV 和性传播感染检测。PROC LCA 确定了五个不同的群体：26%的参与者为禁欲组；酒精和大麻组（16%）；安非他命组（11%）；无酒精性行为组（37%）；和多药组（11%）。多项逻辑回归显示，五个群体的性行为和 condom 使用情况不同：酒精和大麻组发生阴道性交的可能性更高，而无酒精性行为组最有可能在阴道性交中使用 condom。多药组发生肛交的风险最高，而安非他命组和多药组有较高比例的女性有注射毒品使用和男男性行为性伴侣。
根据女性在性行为前后使用药物的情况对其进行分类，可以帮助提供者了解药物使用女性的预防和降低风险的做法和干预措施。
