School practices important for students' sexual health: Analysis of the school health research network survey in Wales

Background: This study investigates how the sexual health outcomes of a representative sample of students aged 15-16 in Wales vary according to the person delivering Sex and Relationships Education (SRE) in schools, students' access to on-site sexual health services and access to free condoms. Methods: Cross-sectional, self-report survey data were collected from students who participated in the 2015/16 School Health Research Network questionnaire in Wales. Data were analyzed from 59 schools, totalling 3781 students aged 15-16 (M= 15.7; SD=0.3) who responded to questions about ever having had sex; age of sexual initiation and condom use at last intercourse. School level data were also collected, examining who delivers school SRE, provision of on-site, school 'drop-in' sexual health services and provision of free condoms for students. Binary and linear multi-level analyses explored the relationship between school level predictors and sexual health outcomes. Results: Compared to teachers, other modes of SRE delivery were associated with better sexual health outcomes, including remaining sexually inactive, later age of first intercourse and condom use. Providing on-site sexual health services did not significantly reduce the odds of having ever had sex or delaying first intercourse; but was associated with increased condom use. Onsite condom provision was associated with lower condom use. Conclusions: SRE delivery by educators other than teachers is optimum to young people's sexual health outcomes. Further funding and coordination of on-site sexual health advice services are required. Longitudinal research is needed to identify the temporal sequence of sexual health practices and outcomes.
