title: Sexual behaviours and associated factors among students at Bahir Dar University: a cross sectional study.
abstract: BACKGROUND
  Sexual behaviour is the core of sexuality matters in adolescents and youths. Their modest or dynamic behaviour vulnerable them to risky sexual behaviours. In Ethiopia, there is scarcity of multicentered representative data on sexual behaviours in students to have a national picture at higher education. This study therefore conducted to assess sexual behaviours and associated factors at Bahir Dar University, Ethiopia.
  
  
  METHODS
  A cross sectional study was conducted among Bahir Dar University students from December to February 2013. Multistage sampling and self administered questionnaires were employed. Descriptive statistics such as frequency and mean were used to describe the study participants in relation to relevant variables. Multivariate analysis was carried for those variables that had a p-value of ≤ 0.2 in the bivariate analysis to identify the predictor variables.
  
  
  RESULTS
  Of the 817 study participants, 297 (36.4%) students had ever had sex. The mean age at first sexual practice was 18.6 years. Unprotected sex, having multiple sex partners, sex with commercial sex workers and sex for the exchange of money was practiced by 184 (62%), 126 (42.7%), 22 (7.4%) and 12 (4%) of sexually active students, respectively. The proportion of attending night clubs and watching porn videos was 130 (15.8%) and 534 (65.4%), respectively. Male respondents had significant positive association with watching porn videos (AOR = 4.8, CI = 3.49 - 6.54) and attending night clubs (AOR = 3.9, CI = 2.3 - 6.7). Watching porn videos, attending night clubs, khat chewing and taking alcohol frequently were significantly associated for ever had sex and having multiple sexual partners. Khat chewing practice (AOR = 8.5, CI =1.31 - 55.5) and attending night clubs (AOR = 4.6, CI = 1.8 - 11.77) had statistical significant association with the purpose of sexual intercourse for the sake of money and for having sex with commercial sex workers, respectively.
  
  
  CONCLUSIONS
  Significant number of students had different risky sexual behaviours. Substance use, attending night clubs and watching porno video were predictor factors for practicing different sexual behaviours. Therefore, preventive intervention programmes should be strengthened, effectively implemented and monitored both in the earlier school and in the universities.
