Determinants of risky sexual behaviour among undergraduate students at the University of Gondar, Northwest Ethiopia.

Risky sexual behaviour (RSB) is defined as behaviours leading to sexually transmitted diseases and unintended pregnancies. According to the Joint United Nations Program on HIV/AIDS, HIV infection was very high among adolescents and youths living in sub-Saharan Africa including Ethiopia. This study was aimed to assess the prevalence of RSB and associated factors among undergraduate students at the University of Gondar.An institution-based cross-sectional study was conducted from June to July 2019 and a simple random sampling technique was employed to select 420 students. Data were collected using a structured self-administered questionnaire, entered into Epi-info version 7.0 and exported to Statistical Package for Social Sciences (SPSS) version 25 for analysis, and presented in frequencies, percentages and tables. Bivariable and multivariable logistic regression analysis were carried out to identify variables having significant association with RSB.The prevalence of RSB among undergraduate students at the University of Gondar was 44.0%. Age [adjusted odds ratio (AOR): 2.12; 95% confidence interval (CI) (1.19-3.79)], residence [AOR: 2.14; 95% CI (1.22-3.75)], living arrangement [AOR: 9.79; 95% CI (5.34-17.9)], daily religious attendance[AOR: 0.57; 95% CI (0.33-0.99)], drink alcohol [AOR: 9.19; 95% CI (3.74-22.59)] and having information about reproductive health and sexually transmitted diseases [AOR:3.05; 95% CI (1.00-9.27)] were factors significantly associated with RSB.Nearly half of the respondents engaged in risky sexual activity. This prevalence is high and the students are at high risk of exposure to sexually transmitted diseases that need reproductive health intervention like counselling and discussion. Creating awareness is needed for the students regarding reproductive health and the risk of sexually transmitted diseases. In addition, giving special attention is required for students who use alcohol, who did not live with family and who have urban residence.
