RESUMO
Senior High School (SHS) students fall within the age group (15-24 years) hardest hit by HIV/AIDS. Since about 90% of HIV transmission in sub-Saharan Africa (SSA) is through heterosexual intercourse, it is assumed that these students engage in risky sexual behaviours. Hohoe municipality has one of the highest HIV prevalence in Ghana (3.4%). The current study investigated the demographic determinants of risky sexual behaviours among senior high school students in the Hohoe municipality, Ghana.Methods: a descriptive cross-sectional design was employed in the study. A pretested structured questionnaire was used to collect data from a multistage sample of 270 SHS students who consented to participate in January 2019. Descriptive and inferential statistics were performed using Stata version 14.0 software program at the 0.05 level of significance.Results: of 270 respondents, 112 (41.5%) were engaged in risky sexual behaviours. Single students were 82% less likely to engage in risky sexual behaviours than their married counterparts (p=0.032) and muslims were 89% less likely to engage in risky sexual behaviours than christians (p=0.032).Conclusion: religion and marital status were the two socio-demographic characteristics that were significantly associated with risky sexual behaviour. Health promotion interventions to curb risky sexual behaviours among the SHS students should target the christian and married students
