This pilot study was carried out in southwest Nigeria to determine the current trends in sexual behaviours known to be associated with HIV transmission in Nigeria. Knowledge of AIDS in general and as an incurable disease was high (91.4% and 79.4% respectively). Knowledge of the means of AIDS transmission was also very high among both men and women. Overall, condom use was consistent at 25%, inconsistent at 55% and non-existent at 20% for all sexually active respondents. Over 60 per cent of sexually active respondents had two or more sexual partners, with significantly more males than females having this number of sexual partners (p < 0.01). Eighteen per cent of sexually active respondents had a history of sex with commercial sex workers while 25% had a history of at least one sexually transmitted disease. Using multiple logistic regression, the significant determinants of condom use among the sexually active group were: being in a stable sexual relationship, history of sex with commercial sex workers, self-perception of testing positive for HIV and self-perception of HIV/AIDS risk in Nigeria. Prevalence of condom use in this study was much higher than those reported in previous studies, suggesting a probable decline in high risk sexual behaviours among inhabitants of urban Southwest Nigeria since the advent of AIDS. Most sexually active respondents aged 19 years or below (adolescents) who perceived themselves at a high risk of testing positive for HIV had never used condoms. The non usage of condoms among this group of adolescents is disturbing, since they are at greatest risk of spreading the disease. Health education and promotion of safe sex practices need to be extensively targeted at adolescents.
这项试点研究在尼日利亚西南部开展，以确定该国已知与艾滋病毒传播相关的性行为的当前趋势。总体而言，对艾滋病以及对其为不治之症的知晓率较高（分别为91.4%和79.4%）。男性和女性对艾滋病传播途径的知晓率也都很高。总体而言，所有性活跃受访者中，始终使用避孕套的比例为25%，不经常使用的为55%，从不使用的为20%。超过60%的性活跃受访者有两个或更多性伴侣，拥有这一数量性伴侣的男性明显多于女性（p<0.01）。18%的性活跃受访者有与商业性工作者发生性行为的历史，25%的人有至少一种性传播疾病的病史。通过多元逻辑回归分析，性活跃人群中使用避孕套的显著决定因素包括：处于稳定的性关系、与商业性工作者发生性行为的历史、自我感觉艾滋病毒检测呈阳性以及自我感觉在尼日利亚感染艾滋病毒/艾滋病的风险。本研究中避孕套的使用率远高于以往研究报告的使用率，这表明自艾滋病出现以来，尼日利亚西南部城市居民的高风险性行为可能有所下降。大多数19岁及以下（青少年）的性活跃受访者，尽管自认为感染艾滋病毒的风险很高，但从未使用过避孕套。这组青少年不使用避孕套的情况令人担忧，因为他们是传播该疾病的最大风险群体。需要广泛针对青少年开展健康教育并推广安全性行为。
