Traditional and new media use links to young people's sexual risk behaviour. The social contexts of young people's daily lives that influence media use and sexual risk behaviour are often investigated as independent causal mechanisms. We examined the link between media use and young people's sexual risk behaviour, considering the intersecting socio-contextual factors in Sub-Saharan Africa.
Age-adjusted bivariate logistic regression models tested the association between traditional media (TV, radio, and newspapers), and new media (mobile phone and online) use and sexual risk behaviour using the Demographic and Health Surveys from six Sub-Saharan African countries among unmarried sexually active youths, aged 15-24 years. Multivariate logistic regression models ascertained the media sources that had an additional influence on young people's sexual risk behaviour, after accounting for socio-contextual factors, and knowledge about HIV and other sexually transmitted infections.
Socio-contextual factors attenuated the association between media use and young people's sexual risk behaviour in many countries. However, those who did not have access to new and traditional media were more likely to use unreliable contraceptive methods or not use contraception. Adolescents in Nigeria who did not own phones were 89% more likely to use unreliable contraceptive methods or not use any methods [(AOR = 1.89 (1.40-2.56), p < .001)], those in Angola who did not read newspapers had higher odds of not using contraception or used unreliable methods [(aOR = 1.65 (1.26-2.15), p < .001)]. Young people in Angola (aOR = 0.68 (0.56-0.83), p < .001), Cameroon [(aOR = 0.66 (0.51-0.84), p < .001)], Nigeria [(aOR = 0.72 (0.56-0.93), p = .01)], and South Africa [(aOR = 0.69 (0.49-0.98), p = .03)] who did not own phones were less likely to have 2 or more sexual partners compared to those who owned phones. Lack of internet access in Mali was associated with lower odds of having 2 or more sexual partners (aOR = 0.45 (0.29-0.70), p < .001). Traditional media use was significantly associated with transactional sex in many countries.
Media use is linked to sexual risk behaviour among young people in Sub-Saharan Africa. Socioeconomic inequalities, levels of globalization, as well as rural-urban disparities in access to media, underscore the need to deliver tailored and targeted sexual risk reduction interventions to young people using both traditional and new media.
传统媒体和新媒体都与年轻人的性风险行为有关。年轻人日常生活中的社会环境通常被视为影响媒体使用和性风险行为的独立因果机制进行调查。我们研究了媒体使用与年轻人性风险行为之间的联系，同时考虑了撒哈拉以南非洲的社会环境因素。
我们使用年龄调整的双变量逻辑回归模型，分析了六个撒哈拉以南非洲国家中，15-24 岁未婚、有性行为的年轻人中，传统媒体（电视、广播和报纸）和新媒体（手机和在线媒体）使用与性风险行为之间的关系。多变量逻辑回归模型确定了在考虑社会环境因素以及对艾滋病毒和其他性传播感染的了解之后，对年轻人性风险行为有额外影响的媒体来源。
在许多国家，社会环境因素削弱了媒体使用与年轻人性风险行为之间的关联。然而，那些无法接触到新老媒体的人更有可能使用不可靠的避孕方法或不使用避孕措施。尼日利亚那些没有手机的青少年使用不可靠的避孕方法或不使用任何避孕方法的可能性要高出 89%[调整后比值比（AOR）=1.89（1.40-2.56），p<.001]；安哥拉那些不看报纸的人不使用避孕措施或使用不可靠方法的几率更高[aOR=1.65（1.26-2.15），p<.001]。安哥拉[aOR=0.68（0.56-0.83），p<.001]、喀麦隆[aOR=0.66（0.51-0.84），p<.001]、尼日利亚[aOR=0.72（0.56-0.93），p=.01]和南非[aOR=0.69（0.49-0.98），p=.03]那些没有手机的年轻人与拥有手机的年轻人相比，发生两次或两次以上性行为的可能性较小。马里缺乏互联网接入与发生两次或两次以上性行为的几率较低有关[aOR=0.45（0.29-0.70），p<.001]。在许多国家，传统媒体的使用与易性交易显著相关。
在撒哈拉以南非洲，媒体使用与年轻人的性风险行为有关。社会经济不平等、全球化程度以及城乡之间获取媒体的差异，强调了需要利用传统媒体和新媒体为年轻人提供有针对性的性风险降低干预措施。
