Sexually transmitted infections can be spread through oral and anal heterosexual sex. There are few data on these practices in Sub-Saharan Africa. We analyzed the prevalence of heterosexual oral and anal sex among HIV Voluntary Counseling and Testing (VCT) attendees in Kinshasa and the associated sociodemographics, perceptions and behavioral factors.
OKAPI (Observational Kinshasa AIDS Prevention Initiative) prospective cohort study. It evaluates the VCT impact on HIV-related knowledge and behaviors at 6 and 12-month follow-up. Since April 2016 until April 2018, 797 persons aged 15-59 years were HIV tested and replied to a baseline interview, including information about anal and oral sex. Descriptive, bi- and multivariate analyses were performed using baseline data.
Among 718 sexually active participants reporting heterosexual sex, 59% had had oral sex, 22% anal sex and 18% both practices. Among participants reporting "not" having had sex, 6% reported oral sex, 3% anal sex and 1% both. Oral sex was associated with a daily use of the Internet/mobile phone, perceiving low community HIV risk, reporting HIV-related behaviors (multiple partners, inconsistent condom use, anal, paid and forced sex) and having been pregnant. Being married-monogamous was inversely associated with oral sex. Anal sex was directly associated with having other risk sexual behaviors.
Oral and anal sex were common among people reporting heterosexual sex in Kinshasa. Perceiving a low community HIV risk and having other sexual risk behaviors are associated with these practices, which are commonly not considered as risky despite their strong association with HIV/STIs. They need to be considered when designing preventive strategies in Kinshasa.
性传播感染可通过异性恋者的口腔和肛门性行为传播。撒哈拉以南非洲地区关于这些行为的数据较少。我们分析了金沙萨艾滋病毒自愿咨询检测（VCT）就诊者异性恋者口腔和肛门性行为的流行情况，以及相关的社会人口学、认知和行为因素。
OKAPI（金沙萨艾滋病预防观察研究）前瞻性队列研究。它评估了 VCT 在 6 个月和 12 个月随访时对与 HIV 相关的知识和行为的影响。自 2016 年 4 月至 2018 年 4 月，797 名 15-59 岁的人接受了 HIV 检测，并在基线访谈中回复了信息，包括有关肛门和口腔性行为的信息。使用基线数据进行描述性、双变量和多变量分析。
在报告异性恋的 718 名活跃参与者中，59%有过口交，22%有过肛交，18%有过两种行为。在报告“没有”过性行为的参与者中，6%有过口交，3%有过肛交，1%有过两种行为。口交与每天使用互联网/手机、认为社区 HIV 风险低、报告与 HIV 相关的行为（多个性伴侣、不坚持使用安全套、肛交、有偿和强迫性行为）以及怀孕有关。已婚一夫一妻制与口交呈负相关。肛交与其他性风险行为直接相关。
在金沙萨，报告异性恋的人中有口交和肛交的情况很常见。认为社区 HIV 风险低和有其他性风险行为与这些行为有关，尽管这些行为与 HIV/性传播感染密切相关，但通常不被视为高风险。在金沙萨制定预防策略时需要考虑到这些行为。
