Univariate, bivariate and multivariate analyses were carried out and the p-value was set at p < 0.05. The majority of the respondents (87.8%) have good knowledge of Risky Sexual Behaviour (RSB). Out of 32.0% who have had sex before, 63.3% were sexually active in the last six months and 82.0% have engaged in RSB.
