BACKGROUND: Years since onset of sexual intercourse (YSSI) is a rarely used variable when studying adolescents' sexual outcomes. The aim of this study is to evaluate the influence of YSSI on the adverse sexual outcomes of early sexual initiators.

METHODS: Data were drawn from the 2002 Swiss Multicenter Adolescent Survey on Health database, a nationally representative cross-sectional survey including 7429 adolescents in post-mandatory school aged 16-20 years. Only adolescents reporting sexual intercourse (SI) were included (n=4388; 45% females) and categorised by age of onset of SI (early initiators, age

RESULTS: After adjusting for YSSI instead of age, negative sexual outcomes among early initiators were no longer significant, except for multiple sexual partners among females, although at a much lower level. Early initiators were less likely to report condom non-use at last SI when adjusting for YSSI (females: AOR=0.59 [0.44-0.79], P

CONCLUSION: YSSI is an important explanatory variable when studying adolescents' sexuality and needs to be included in future research on adolescents' sexual health.
