The French overseas territories in the Americas are the French territories most affected by HIV. Crack cocaine users are particularly impacted. The objective of this study was to describe sexual risk behaviors and inconsistent condom use among crack cocaine users. A total of 640 crack cocaine users were interviewed. The sampling method was non-probabilistic. An anonymous standardized questionnaire of 110 questions was used. Over a third of persons did not use condoms systematically with casual sex partners (36.2%) or commercial sex partners (32.3%), and 64% did not use condoms systematically with regular sex partners. In a context of multiple sexual partnerships, frequent forced sex, and insufficient HIV testing, the lack of systematic condom use may favor the spread of HIV. Different predictive factors of inconsistent condom use were identified, depending on the type of partner, with a log binomial regression. However, among the predictor variables identified, two predictive factors frequently occur among the different type of sex partners: high perceived risk of HIV and self-perceived capacity to persuade a sex partner to use condom. These results pointed towards interventions improving access to rights and raising perceived self-efficacy.
美洲的法属海外领地是受艾滋病毒影响最严重的法国领土。快克可卡因使用者受到的影响尤为严重。本研究的目的是描述快克可卡因使用者的性风险行为及避孕套使用不一致的情况。共对640名快克可卡因使用者进行了访谈。抽样方法为非概率抽样。使用了一份包含110个问题的匿名标准化问卷。超过三分之一的人在与临时性伴侣（36.2%）或商业性伴侣（32.3%）发生性行为时未始终使用避孕套，64%的人在与固定性伴侣发生性行为时未始终使用避孕套。在存在多个性伴侣、频繁发生强迫性行为以及艾滋病毒检测不足的情况下，不始终使用避孕套可能会助长艾滋病毒的传播。通过对数二项回归分析，确定了与避孕套使用不一致相关的不同预测因素，具体取决于性伴侣的类型。然而，在确定的预测变量中，有两个预测因素在不同类型的性伴侣中经常出现：高感知艾滋病毒风险和自我感知的说服性伴侣使用避孕套的能力。这些结果表明需要采取干预措施来改善权利获取情况并提高自我效能感。
