The population of the adolescents has been on the increase globally, representing more than 17 percent of the total population. Adolescence is a stage where sexual desires and anxieties are high. Majority of them are tempted to engage in sexual activities that expose them to all sexual related risks. Risky sexual behaviour is a common habit among young people in the world, but its relation with the media has not been explored exhaustively, especially in Kenya. There is growing concern about young people's exposure to sexual content through television and other electronic media and about its potential effects on their sexual behaviors. Adolescents in Kenya are increasingly accessing television which has become more saturated with sexual content. The content rarely includes messages on safe sex or consequences of engaging in premarital sexual behaviour. This exposure may influence the behaviour and attitudes of the adolescents negatively leading to them to engage in premarital sexual behaviour leading to unwanted pregnancies among other effects.Researchers have documented the growing prevalence of sexual talk and portrayals of sexual behavior in televised media, as well as associations between adolescent viewing patterns and their sexual activities. Youth spend an average of 7 hours per day using media, and the vast majority of them have access to a bedroom television, computer, the Internet, a video-game console, and a cell phone. The literature review in this paper has the specific goals of establishing the sexual behaviour of the youth in Kenya as well as explore the most recent research on the effects of media on the risky sexual behaviour of adolescents. This paper also establishes the extent to which the youth are exposed to sexual content and the effect of the exposure on the sexual behaviour of the youth. The literature review in this paper also examines the influence of media sex on youth within the context of the Social Learning Theory. Finally, this paper provides recommendations for parents, public health professionals, researchers studying adolescent sexual behaviour and/or media use, the media, and policy makers, among others, for ways to increase the benefits and reduce the harm that media can have for the adolescents.
