Determinants of sexual abuse were female sex (OR=2.234, CI= 1.532 – 3.527, p<0.001), room sharing (OR=2.637, CI= 0.416 – 0.977, p = 0.039), self-support in school (OR = 2.587, CI= 0.416 – 0.977, p = 0.036), history of previous sexual abuse (OR = 6.043, CI= 3.689 – 6.238, p = 0.001) and history of abusive relationship (OR= 5.010, CI= 1.321 – 3.234, p = 0.023).
