Prevalence and factors associated with perpetration of non-consensual sex among students of a tertiary institution in Ibadan, Nigeria.

This cross-sectional survey explored the extent to which students of the Polytechnic, Ibadan had perpetrated Non-Consensual Sex (NCS). A total of 594 randomly selected students completed a questionnaire and three perpetrators were interviewed in-depth. Mean age of the survey respondents was 22.7 +/- 2.9 years. Twenty-two percent had ever perpetrated at least a form of NCS, out of which 75.9% reported involvement in this behaviour in the six months preceding the study. Forms of NCS perpetrated included unwanted touch of breast/back side (14.6%), unwanted kiss (9.4%), attempted rape (2.7%) and rape (1.7%). The predictors of perpetration of NCS were alcohol use (OR: 2.2; CI: 1.41-3.33) and cigarette smoking (OR: 2.5, CI: 1.13-5.56). In-depth interview revealed that peer group influence and alcohol consumption contributed to perpetration of NCS. Behavioural change interventions are recommended to prevent perpetration of NCS in this institution.
