我们的主要目的是研究甲基苯丙胺的使用和性冒险行为之间的关系，性伴侣的数量，与定期和临时合作伙伴的性行为的频率，交易金钱或毒品的性行为，以及安全套的使用，在男性和女性的治疗注射毒品使用者（OTIDUs）。作为人类免疫缺陷病毒（HIV）传播的风险群体，我们还调查了甲基苯丙胺使用的注射行为。数据收集自加州弗雷斯诺、萨克拉门托和圣地亚哥县的1392个OTIDU。这项横断面调查排除了自1978年以来仅与男性或主要与男性发生性关系的男性OTIDU。在双变量分析中，我们发现有甲基苯丙胺使用史的男性OTIDU比从未使用甲基苯丙胺的男性OTIDU有更多的性伴侣，并且与临时伴侣进行肛门插入性交以及与定期和临时伴侣进行阴道性交的行为更多。此外，使用甲氧非他胺的男性吸毒过量者中有更大比例的人报告说，他们以性换取金钱或毒品。与从不使用甲基苯丙胺的女性OTIDU相比，使用甲基苯丙胺的女性OTIDU参与了更多与固定男性性伴侣的阴道性交行为。通过多因素Logistic回归分析，我们发现甲基苯丙胺的使用与男性OTIDU和女性OTIDU的性伴侣中安全套的使用有关。判别函数分析显示，男性OTIDUs中甲基苯丙胺的使用可以区分性风险，甲基苯丙胺的使用也与男性和女性OTIDUs中共用针头或注射器有关，并不总是用漂白剂消毒使用过的针头或注射器。我们的研究结果表明，甲基苯丙胺可能有助于异性恋艾滋病毒传播。
Our primary objective was to examine the relationship between methamphetamine use and sexual risk-taking behaviors-number of sexual partners, frequency of sexual behaviors with regular and casual partners, trading money or drugs for sex, and condom use-among male and female out-of-treatment injection drug users (OTIDUs). As a risk group for human immunodeficiency virus (HIV) transmission, we also investigated injection behaviors by methamphetamine use. Data were collected from 1392 OTIDUs within the California counties of Fresno, Sacramento, and San Diego. Excluded from this cross-sectional survey were male OTIDUs engaging in sex with only or mostly men since 1978. In bivariate analyses, we found that male OTIDUs with a history of methamphetamine use had more sex partners and participated in more acts of anal insertive intercourse with casual partners and vaginal intercourse with regular and casual partners than male OTIDUs never using methamphetamines. In addition, a greater percentage of male OTIDUs using methomphetamines reported trading sex for money or drugs. Methamphetamine-using female OTIDUs participated in more acts of vaginal intercourse with regular male sex partners than female OTIDUs never using methamphetamines. By multivariate logistic regression, we found methamphetamine use related to consistent condom use among male OTIDUs and among mole sex partners of female OTIDUs. Discriminant function analyses revealed that sexual risk taking could be differentiated by methamphetamine use among male OTIDUs, methamphetamine use also correlated with using shared needles or syringes among male and female OTIDUs and was related to not always disinfecting used needles or syringes with bleach. Our findings suggest that methamphetamines may contribute to heterosexual HIV transmission.
