Abstract
OBJECTIVE: To assess the magnitude and factors associated with premarital sexual intercourse among adolescent students of the secondary and preparatory school in Debre-Markos town, northwest Ethiopia, 2017. RESULTS: Among secondary and preparatory school adolescent students, 31.3% reported pre-marital sexual intercourse. This shows that premarital sexual intercourse among secondary and preparatory school adolescents is high. Significantly associated factors were: being male (AOR = 1.9, 95% CI 1.21, 2.93), having pocket money (AOR = 3.1, 95% CI 2, 4.81), adolescents who did not discuss sexual issue with close friends (AOR = 8.6, 95% CI 5.27, 13.91) and peer pressure (AOR = 7.7, 95% CI 3.73, 15.69).
