Longitudinal Risk Factors of Selling and Buying Sexual Services Among Youths in Switzerland

The aim of this study was to examine the longitudinal predictors of buying and selling sexual services among youths in a high-income country. We used data from Switzerland (target sample: N = 1675 children, 52% male), where no prior studies have examined the trading of sexual services among representative samples of youths. Selling and buying sexual services were measured using novel, three-item measures at age 17. The predictors were measured at ages 13 and 15. In the regressions, multiple imputation was used to treat the missing values. Two-year point prevalence estimates of selling sexual services were 2.5% for females and 1.5% for males. Prevalence estimates of buying sexual services were 0.0% for females and 5.4% for males. Findings from logistic regressions revealed some support for prior findings from cross-sectional studies in high-income countries. New findings included evidence for prospective relations of having a disability, low generalized trust, and endorsing masculinity norms with trading sexual services. Follow-up models showed that the relations between pornography consumption and victimization with selling sexual services were gendered and stronger for females than for males
