목적: 한국 청소년들의 성의식 실태와 성행태를 파악하여 적절한 대처 방안을 마련함으로써 우리나라 청소년들의 건강을 증진시키고자 조사하였다. 연구 방법: 2007년 9월 1일부터 9월 22일 기간 중 13~18세의 청소년들인 중고등학교 재학생 8만명을 대상으로 하였다. 성행태 영역에 관련된 조사지표 10항목으로 구성된 설문지를 이용하여 ‘자기기입식 온라인 조사방식’으로 수행하였다. 결과: 전체 조사 대상자는 78,834명이었으며 응답자는 74,698명으로 94.8%의 응답률을 보였다. 조사 대상자의 일반적 특성은 남학생이 39,466명 (52.8%), 여학생이 35,232명 (47.2%)였다. 학교 급별로는 중학교 38,820명 (52.0%), 일반계고 25,051명 (33.5%), 전문계고 10,827명 (14.5%)였다. 성관계 경험률은 전체 5.2%였고, 남학생이 여학생 보다 높았다. 성관계 시작 연령은 전체 14.2세였으며, 중학교 입학 전 성관계 경험률은 전체 1.0%였고, 남학생이 여학생 보다 높았다. 임신 경험률은 0.3%였다. 성관계 경험자 중 피임 실천율은 전체 38.2%로 남학생이 여학생보다 높았다. 부적절한 피임법 사용률은 전체 21.6%였다. 남학생의 첫 몽정 시작 연령은 13.2세였으며 여학생의 월경 시작 연령은 12.4세였다. 연간 성교육 경험률은 전체가 72.2%이며 여학생이 남학생보다 높았다. 결론: 본 조사 결과 한국 청소년들의 몽정이나 월경 시작 연령이 저령화되고 있었다. 성관계 시작 연령 또한 저령화되고 있었고, 성관계 경험률은 증가하는 추세였다. 그러나 적절한 피임법의 사용률은 낮았다. 그러므로 청소년들의 원하지 않는 임신을 예방하기 위해서 효과적인 피임법을 포함한 적절한 성교육이 시행되어야 하겠다.

The average age of the first sexual intercourse was 14.2 years old. 1.0% of respondents had a sexual intercourse before they enter the middle school. The pregnancy rate was 0.3%. Among respondents who experienced sexual intercourse, the rate of the use of contraceptive methods was 38.2%. The rate of using inappropriate contraceptive methods was 21.6%. The average age of a first wet dream for boys was 13.2 years old. The average age of menarche for girls was 12.4 year old. The rate of respondents who had a sex education was 72.2%. Conclusion: The average age of the first wet dream and menarche had been decreased. The average age of the first sex experience among adolescents had been decreased.
