Oral and anal sexual behaviours are increasingly reported among adolescents and adults reporting heterosexual sex in peer-reviewed journals in high income countries, but less is known about these behaviours in low and middle-income countries, especially in sub-Saharan Africa. The aim of this systematic review is to describe the prevalence of, and motivations for, oral and anal sex among adolescents and adults reporting heterosexual sex in sub-Saharan Africa.
A systematic review of published articles that reported oral and or anal sex in sub-Saharan Africa was conducted from seven databases up to and including 30th August 2018.
Of 13,592 articles, 103 met the inclusion criteria. The prevalence of reporting ever practising oral sex among adolescents, university students and a combined population of adolescents/adults ranged from 1.7-26.6%, 5.0-46.4% and 3.0-47.2% respectively. Similarly, prevalences of reported ever practising anal sex ranged from 6.4-12.4% among adolescents, 0.3-46.5% among university students and 4.3-37.8% amongst combined population of adolescents and adults. Higher prevalences of oral and anal sex were reported among populations at high-risk for sexually transmitted infections and HIV and university students and, in most studies, both behaviours were more commonly reported by males than females. Heterosexual oral and anal sexual acts were associated with some high-risk behaviours such as inconsistent condom use and multiple sexual partners.
Reported oral and anal sex between men and women are prevalent behaviours in sub-Saharan Africa. Health professionals and policy makers should be aware of these behaviours and their potential associated health risks.
在高收入国家的同行评议期刊中，报告异性性行为的青少年和成年人中越来越多地报告口交和肛交行为，但在中低收入国家，特别是撒哈拉以南非洲，这些行为的情况了解较少。本系统评价的目的是描述撒哈拉以南非洲报告异性性行为的青少年和成年人中口交和肛交的流行率和动机。
从七个数据库中对截至 2018 年 8 月 30 日发表的报告撒哈拉以南非洲地区口交和/或肛交的文章进行了系统评价。
在 13592 篇文章中，有 103 篇符合纳入标准。青少年、大学生和青少年/成年人综合人群中报告曾经有过口交的比例分别为 1.7-26.6%、5.0-46.4%和 3.0-47.2%。同样，报告曾经有过肛交的比例在青少年中为 6.4-12.4%，大学生中为 0.3-46.5%，青少年和成年人综合人群中为 4.3-37.8%。在性传播感染和艾滋病毒高危人群以及大学生中，口交和肛交的比例较高，在大多数研究中，这两种行为都更为男性所报告。异性恋的口交和肛交行为与一些高危行为有关，如不坚持使用避孕套和多个性伴侣。
在撒哈拉以南非洲，报告的男女性之间的口交和肛交行为是普遍存在的行为。卫生专业人员和政策制定者应该意识到这些行为及其潜在的相关健康风险。
