    The median age for first sexual intercourse in Danish adolescents aged 16-20 was 16.8 years for both sexes. This finding reflects a declining age at sexual debut for females, while remaining stable for males over two decades.

    Area of Science:

    • Sociology
    • Public Health
    • Demography

    Background:

    • Understanding adolescent sexual behavior is crucial for public health initiatives.
    • Sexual debut patterns can vary significantly across different populations and time periods.
    • Previous research indicates shifts in the age of sexual initiation among young people.

    Purpose of the Study:

    • To determine the median age at sexual debut in a representative sample of Danish adolescents.
    • To analyze trends in the age of sexual debut for males and females over a 20-year period.
    • To provide data for public health planning and adolescent sexual education programs.

    Main Methods:

    • A cross-sectional study was conducted in 1984-85 involving 286 females and 336 males aged 16-20 years.

  • Data on sexual debut was collected through interviews.
  • Maximum likelihood estimation was employed to calculate the age distribution at sexual debut, accounting for non-respondents and those who did not report their age.

    • Main Results:

    • The median age at first sexual intercourse was approximately 16.8 years for both females and males.
    • 25.9% of females and 30.1% of males reported no prior sexual intercourse.
    • Analysis suggested a declining trend in the age of sexual debut among females and a stable trend among males over the preceding 20 years.

    Conclusions:

    • The median age of sexual debut in Danish adolescents is around 16.8 years.
    • Trends indicate a divergence, with females initiating sexual activity earlier over time, while males' age at debut remained consistent.
    • These findings highlight the importance of monitoring and understanding evolving adolescent sexual behaviors.
