Unprotected oral sex is associated with sexually transmitted infections (STIs) including HPV and associated head and neck cancers. However, many studies lack clear definitions of oral sex and there are few data from West Africa. This study assessed the pattern and prevalence of, and factors associated with oral sex among Nigerian men and women from the general population.
The Sexual Behaviours and HPV Infections in Nigerians in Ibadan (SHINI) study was a cross-sectional study conducted among men and women aged 18-45 years. Information on oral sexual behaviours was collected during a face-to-face interview by a sex-matched interviewer. Descriptive and multivariable analyses were used to analyse factors associated with oral sex in men and women.
In total, 160/626 (26%) had ever any type of oral sex. Specifically, 78/626 (12%) had ever given and 139/626 (22%) had ever received oral sex in a heterosexual relationship. Overall, 35% (112/310) men had ever engaged in oral sex compared to women 15% (48/316 -p < 0.001). More men frequently reported ever receiving oral sex than women (33% vs. 12%; p < 0.001). There was no difference in the proportion of men and women that reported ever giving oral sex. Most (94%) participants never used any barrier protection during oral sex. Most men and women participants engaged in oral sex because of romantic relationship or being married. In the adjusted models, there was a higher odds of ever receiving oral sex (Adjusted odds ratio = AOR 4.01 95% CI 2.52-6.38) or engaging in any form of oral sex (AOR = 3.12, 95%CI 2.04-4.76) in men than women.
Though, Nigerian men and women engage in oral sex in heterosexual relationship, but it is more commonly reported by men than women and most of them practiced it without barrier protection. It is recommended that sexually active men and women are counselled on risks associated with unprotected oral sex including STIs, HIV and HPV and associated cancers.
无保护口交与包括人乳头瘤病毒（HPV）及相关头颈癌在内的性传播感染有关。然而，许多研究对口交缺乏明确的定义，且来自西非的数据很少。本研究评估了尼日利亚普通人群中男女口交的模式、患病率及其相关因素。
伊巴丹尼日利亚人性行为与HPV感染（SHINI）研究是一项针对18至45岁男女开展的横断面研究。关于口交行为的信息由性别匹配的访谈者在面对面访谈期间收集。采用描述性和多变量分析来分析男女口交的相关因素。
总计160/626（26%）的人曾有过任何类型的口交。具体而言，78/626（12%）的人曾在异性恋关系中进行过口交施予，139/626（22%）的人曾在异性恋关系中接受过口交。总体而言，35%（112/310）的男性曾有过口交行为，而女性为15%（48/316 -p＜0.001）。经常报告曾接受口交的男性多于女性（33%对12%；p＜0.001）。报告曾进行口交施予的男女比例无差异。大多数（94%）参与者在口交期间从未使用任何屏障保护措施。大多数男性和女性参与者进行口交是因为恋爱关系或已婚。在调整模型中，男性曾接受口交（调整优势比=AOR 4.01，95%置信区间2.52 - 6.38）或进行任何形式口交（AOR = 3.12，95%置信区间2.04 - 4.76）的几率高于女性。
尽管尼日利亚男女在异性恋关系中会进行口交，但男性比女性更常报告有此行为，且大多数人在无屏障保护的情况下进行。建议对性活跃的男女进行咨询，告知他们无保护口交相关的风险，包括性传播感染、艾滋病毒、HPV及相关癌症。
