Predictors and consequences of early sexual debut among students in tertiary institutions in Lagos metropolis, Nigeria.

This study investigated the factors associated with early sexual debut, consensual sexual debut and multiple sexual partners in tertiary institutions in Lagos Metropolis, Nigeria. The study adopted a cross-sectional survey design with a proportional sampling method. Structured questionnaire was used to elicit information from respondents. Four hundred and thirty-three questionnaires were deemed eligible for data analysis. Chi-square, t-test and binary logistic regression were utilised to analyse the data. It was found that respondents who attended private secondary schools were more likely to have early sexual debut (X2= 3.076; p <0.05). There was no significant difference in the age at sexual debut for respondents from nuclear and extended families (M.D = - 0.377). Females were less likely to experience consensual sexual debut than their male counterparts (OR=0.469; p <0.01). Also, early sexual debut influenced exposure to multiple sexual partners- those who delayed sex till age 22 were the least likely to be exposed (OR= 0.056; p <0.001). Adequate sex education of young people-beginning at early years- before their sexual debut is important for improved sexual health.
