Summary
Objectives: The aim of this study was to report on trends in the prevalence in age at first intercourse of Czech schoolchildren and a difference between sexes. Methods: Prevalence in age at first intercourse of Czech schoolchildren was observed under the Health Behaviour in School-aged Children study in the years 2002, 2006, 2010 and 2014. In addition, a random representative sample of children attending 9th grade completed the questions related to sexual behaviour. A total of 4,804 boys and girls at the age of 15 years were included in the study. The chi-square test and analysis of variance were used for data assessment. Results: Experience with first sexual intercourse before 15 years was confirmed by 16% of boys and 19.4% of girls. Average age of coitarche in both sexes most often ranged between 14 and 15 years. Since 2006 boys had significantly lower age at coitarche. Only in 2010 the girls had first intercourse more frequently than boys. Since 2010 the number of Czech adolescents of both sexes having first intercourse before the age of 15 years has significantly increased. However, a rise in average age of coitarche over 15 years in both sexes occurred in 2014. Conclusions: The number of Czech children having a sexual intercourse before 15 years has significantly increased since 2010.

Keywords: age at first sexual intercourse, coitarche, schoolchildren
