Sexual initiation and associated factors among young women in West Shoa, Ambo Town, Ethiopia: a community-based cross-sectional study

Background: For physiological as well as behavioral reasons, sexual debut increases young individuals' risk for infection with sexually transmitted infection including HIV. It is fundamental to recognize the factors related to sexual debut in a broader context for designing and implementing effective interventions targeting youth. Methods: Community based cross sectional study was employed from January to May, 2013 among females of Ambo town. A multistage sampling technique was applied. The participants were selected using simple random sampling technique. Face to face interview using structured and pretested questionnaires were used to collect thedata from the study participants. Bivariate and multivariate logistic regression analysis was used to determine the predictors of sexual initiation. Results: Three hundred seventeen (49.9%) of the respondents have ever had sex. The mean age at first sexual initiation was 16.6 (SD +/- 2.3) years. Being in age group 20-24 [Adjusted Odds Ratio (AOR) & (95%CI) = 2.75 (1.74,4.34)], Educational level [AOR&(95% CI) = 0.20 (0.08, 0.48)], being in school [AOR&(95% CI) = 0.19 (0.11, 0.33)], having paid job [AOR&95% CI) = 2.20 (1.19, 4.07)], peer pressure [AOR&(95% CI) = 3.20 (2.08, 4.94)], alcohol consumption [AOR&(95% CI) = 2.17 (1.43, 3.28)], and pornographic materials [AOR&(95% CI) = 2.27 (1.43, 3.61)] had significant association with sexual initiation. Conclusion: Substantial numbers of females had started sexual activity that might expose them to different reproductive health problems. In general age group, peer pressure, alcohol consumption and watching pornographic materials were found to be predictors for the sexual debut. Therefore, building life skills, establishing youth friendly clubs should be intensified.
