Globally, HIV/AIDS remains a public health issue, especially in sub-Saharan Africa (SSA). Despite the increased advocacy and dissemination of comprehensive HIV/AIDS information in SSA, it appears that little progress has been made to reduce the incidence of HIV/AIDS in the sub-region. This study, therefore, examined the association between comprehensive HIV/AIDS knowledge and safer sex negotiation among adolescent girls and young women in SSA. Data were taken from the Demographic and Health Surveys conducted between 2010 and 2019 in 30 countries in SSA. The study sample comprised 37,364 adolescent girls and young women aged 15–24. A multivariable binary logistic regression analysis was done to test the hypothesis that there is a positive association between comprehensive HIV/AIDS knowledge and safer sex negotiation. Adolescent girls and young women who had comprehensive knowledge on HIV/AIDS were more likely to negotiate for safer sex compared with those who had no comprehensive knowledge on HIV/AIDS (AOR=1.31, 95% CI: 1.22–1.41). At the country level, the positive association between comprehensive knowledge on HIV/AIDS and safer sex negotiation was significant in Chad, Congo DR, Gambia, Guinea, Liberia, Ethiopia and Malawi. On the other hand, in Togo, adolescent girls and young women who had comprehensive HIV/AIDS knowledge were less likely to negotiate for safer sex. These findings can inform policies and programmes on the crucial role of comprehensive HIV/AIDS education and knowledge in increasing safer sex negotiation among adolescent girls and young women in SSA. The study recommends that Togo needs to address certain practices such as intimate partner violence against adolescent girls and young women, which prevent them from negotiating for safer sex, despite their higher knowledge on comprehensive HIV/AIDS. Lessons can be learnt from Chad, Congo DR, Gambia, Guinea, Liberia, Ethiopia and Malawi about the scale-up of programmes and interventions targeted at young women.

在全球范围内，艾滋病毒/艾滋病仍然是一个公共卫生问题，尤其是在撒哈拉以南非洲 (SSA)。尽管在 SSA 加强了对艾滋病毒/艾滋病综合信息的宣传和传播，但该次区域在减少艾滋病毒/艾滋病发病率方面似乎进展甚微。因此，本研究调查了 SSA 的少女和年轻女性中全面的 HIV/AIDS 知识与安全性行为协商之间的关联。数据取自 2010 年至 2019 年期间在 SSA 的 30 个国家/地区进行的人口和健康调查。研究样本包括 37,364 名 15-24 岁的少女和年轻女性。进行了多变量二元逻辑回归分析以检验全面的 HIV/AIDS 知识与安全的性行为谈判之间存在正相关关系的假设。与不具备全面艾滋病知识的少女和年轻女性相比，具备全面艾滋病知识的少女和年轻女性更有可能就安全性行为进行谈判（AOR=1.31，95% CI：1.22–1.41）。在国家层面，在乍得、刚果民主共和国、冈比亚、几内亚、利比里亚、埃塞俄比亚和马拉维，关于艾滋病毒/艾滋病的综合知识与安全性行为谈判之间的正相关关系非常显着。另一方面，在多哥，拥有全面 HIV/AIDS 知识的少女和年轻女性不太可能就更安全的性行为进行谈判。这些发现可以为政策和项目提供信息，让他们了解全面的 HIV/AIDS 教育和知识在提高 SSA 少女和年轻女性安全性行为谈判方面的关键作用。该研究建议多哥需要解决某些习俗，例如亲密伴侣对少女和年轻女性的暴力行为，这些习俗会阻止她们就安全性行为进行谈判，尽管她们对艾滋病毒/艾滋病的综合了解更高。可以从乍得、刚果民主共和国、冈比亚、几内亚、利比里亚、埃塞俄比亚和马拉维吸取经验教训，扩大针对年轻女性的计划和干预措施。
