The influence of adolescents’ exposure to sexual health content of mass media in their sexual health behaviour in Nigeria is still
not clear. Data were gathered through a survey conducted among adolescents aged 12-19 years in Lagos metropolis between
November 2009 and February 2010. A multistage sampling strategy was adopted in selecting respondents. Logistic regression
technique was utilised in the analysis. The results indicate that the respondents were most frequently exposed to TV (male=92.2;
female=94.9) and radio (male=88.2; female=91.7) media. The odds ratios indicate that sexual health content of mass media
significantly predicted condom use, multiple sexual relationship, sexual intercourse and self reported occurrence of abortion in
the study sample. The findings imply that positive media sexual health content is likely to promote sexual health among
adolescents but negative contents can put adolescents’ sexual health in danger. In addition, safe sex can be advanced among
adolescents if the media provide accurate information on sexuality, emphasising the dangers of risky sexual practices. Finally,
this study posits that accurate portrayal of sexuality in the media would contribute immensely to improving public health in the
metropolis.
