[Sex under the age of 25 in 2017: the sexual health of young people in the Netherlands].

OBJECTIVE: To gain insight in the sexual health of young people aged 12 to 25 in the Netherlands. Municipal health services and other stakeholders in the area of the promotion of sexual health were involved in various phases of this study, the results of which can be applied better to maintaining or improving the sexual health of young people. DESIGN: Large-scale representative study with a cross-sectional design which was previously conducted in 2005 and 2012. METHOD: We used data from students in secondary education (aged 12-16 years) as well as data from a sample drawn from the municipal population registers (aged 17-24 years). Fifteen municipal health services recruited extra respondents from their own regions, so that they obtained reliable and representative figures on the sexual health of young people at a local level. This investment also led to a total of 20,500 young people filling in a digital questionnaire containing questions on a wide range of sexuality-related topics. RESULTS: The study shows that young people are having their first sexual experiences at a later age and protect themselves well against pregnancy. New developments were also apparent in the use of online media for 'sexting' and meeting partners. Condom use was low, particularly with casual partners, and despite a reduction in sexual violence it still occurs too frequently. CONCLUSION: Sexual health among young people is generally good, but there are still concerns. The findings of this study were discussed with professionals working in the field of young people and sexual health. Their recommendations on interventions, care and policy resulting from these discussions will be included in a national action plan.
