Since exposure to sexual content and early sexual initiation among adolescents have become serious social issues in Korea, an in-depth analysis of trends in the prevalence of sexual experience among Korean adolescents is necessary to project the trends and policies required for the next 10 years. The objective of this study was to identify the contributions of age, period, and birth cohort effects on the prevalence of sexual experience in Korean adolescents.
We analyzed age-specific, period-specific, and birth cohort–specific trends in the prevalence of sexual experience among 911,502 adolescents (469,593 boys, 51.5%; 441,909 girls, 48.5%) aged 12 years to 17 years from the 2006 to 2017 Korean Youth Risk Behavior Web-based Survey. Joinpoint regression analysis was conducted to examine significant changes in the prevalence of sexual experience and to find the optimal number and location of places where trends changed.
The prevalence of sexual experience generally increased with age in all periods in both boys and girls. In boys, the prevalence of sexual experience increased in recent periods, especially in the age group of 12-13 years, while the prevalence of sexual experience decreased in the age group of 16-17 years. In girls, the age group of 12-13 years showed an increased prevalence of sexual experience in recent periods. However, the prevalence showed a decreasing trend in the age group of 16-17 years.
In boys and girls, sexual experience increased with age, although this tendency has slowed in recent cohorts. Therefore, early sex education is needed.
Korean summary
성경험 유병률은 일반적으로 남녀 공히 모든 시기에서 연령대에 따라 증가했다. 공통적으로 최근 연도에서 12-13세 연령군의 성 경험 유병률이 증가한 반면 16-17세 연령군에서 성경험 유병률이 감소했다. 전반적으로 2006 년부터 2017 년까지 청소년들의 성경험률은 소폭 감소했지만, 조기 성경험의 빈도는 증가하고 있다. 따라서 피임이나 순결 교육뿐만 아니라 성적자기결정능력같은 보다 실질적인 성교육이 어릴 때부터 강화되어야 할 것으로 보인다.
