Factors associated with unwanted sexual experiences of young Australian females: an observational study.

UNLABELLED: Background Behavioural and lifestyle factors associated with childhood unwanted sexual experiences (USE) have yet to be investigated in Australian females aged less than 18 years.

METHODS

Women aged 16-25 years living in Victoria were recruited via targeted advertising on Facebook. A web-based validated questionnaire was used to collect information on participant demographics, mental health, USE and sexual behaviours. Multivariable logistic regression was used to determine associations between a history of childhood (<16 years) and adolescent (16-18 years) USE and indices of sexual orientation.

RESULTS

Data were collected from 639 females (mean±s.d. age 22±3 years). Approximately 14% reported childhood USE and 15% reported adolescent USE. Approximately 37% of survivors of childhood USE reported penile-genital contact in relation to their USE. Participants who reported depression were almost four times as likely to have experienced childhood USE than those who did not report suffering from depression (odds ratio 3.6, 95% confidence interval 2.1-6.0, P<0.001). Positive associations between childhood USE, same-sex relationships and smoking were also detected.

CONCLUSIONS

A strong relationship between childhood USE, depression and same-sex sexual behaviours was found, but results did not determine the direction of this association. Longitudinal studies should be conducted to investigate whether there are groups of individuals who are at a high risk of experiencing childhood USE, so that appropriate support systems can be put in place.
