Abstract
Sexual activity is rampant among female undergraduates with the consequence of unintended pregnancies, abortions and sexually
transmitted infections. This study was conducted to assess the prevalence and predictors of unprotected sexual intercourse and
abortion; the knowledge, access to and use of contraceptives; as well as the knowledge of and exposure to Sexually Transmitted
Infections among undergraduates of the Polytechnic and University of Ibadan. It was a descriptive cross-sectional study that
employed a multi-stage sampling method. A structured questionnaire was administered to undergraduates of the Polytechnic of
Ibadan (PTI) and the University of Ibadan (UI). Data were collected on demographic profile; reproductive and sexual history;
knowledge, attitude to and use of contraceptives; and knowledge of and exposure to Sexually Transmitted Infections. Analysis
was done using SPSS version 15.0. Significantly more males than females (27% vs 18%) were sexually active and more (25%)
students of PTI than UI (19%). Abortion was significantly more prevalent in the Polytechnic (5.3%) than the University (1.6%).
The major reason pregnancies were aborted was that they were unplanned for and abortion seekers were not ready for consequent
financial responsibilities (57%) of keeping the pregnancies. Knowledge of the various forms of contraception was poor. Males
had better access to contraceptives than females and significantly more males (36%) than females (6%) used contraceptives
always. Overall, self-pleasure was the single principal reason (75.4%) respondents had for sexual intercourse and significantly
more females (21.6%) than males (12.5%) had sex to please their partner(s). Knowledge about sexually transmitted Infections
was assessed as fair.
