Abstract

Purpose : The purpose of this study was to evaluate the timing of puberty and the factors inducing advanced puberty in elemental school students of low grades. Methods : The 1st, 2nd, and 3rd grade elemental students from the Goyang province were randomly selected, and their sexual maturation rate was assessed by physical examination. After obtaining an informed consent, a questionnaire was administered to the parents; eating habits, lifestyle, use of growth-inducing medication, and present illness of the students were evaluated to determine the factors that induced advanced puberty. The data were statistically analyzed. Results : We selected 170 children and the girls:boys sex ratio was 1.2:1. Two 9-year-old boys were in genital stage 2. Two (14.3%) 6-year-old girls, 6 (19.4%) 7-year-old girls, 15 (39.6%) 8-year-old girls, and 4 (57.1%) 9-year-old girls were in breast stage 2. The average pubertal timing predicted for girls was $9.11{\pm}1.86$ years. The main factors influencing pubertal timing were obesity scale, frequency of eating fast food, and the use of growth-inducing medication. A high rating on the obesity scale and high frequency of eating fast food indicated advanced stage of puberty. Growth-inducing medication induced puberty through obesity. Conclusion : We proposed that predictive average pubertal timing in girls was 9.11${\pm}$1.86 years, which was consistent with the previously reported findings from abroad. The significant influencing factors in advanced puberty were obesity scale and frequency of fast food.

목 적 : 저자들은 우리나라 초등학교 저학년의 사춘기 발현 시기를 조사하고, 사춘기 발현시기에 영향을 미치는 인자에 대해서 연구하고자 하였다. 방 법 : 고양시 관내 초등학교 1, 2, 3학년 학생들을 무작위로 선별하여 신체검진을 통해 이차성징의 발현유무를 조사하였다. 부모의 동의와 함께 설문조사를 하여 비만도, 식생활 패턴, 생활습관, 성장촉진제품 복용여부 등을 조사하여 사춘기 조기 발현의 영향인자를 통계학적으로 분석하였다. 결 과 : 총 170명의 학생이 선별되었으며 남녀비는 1:1.2였다. 대상 환아들의 연령은 6-9세였으며, 각 연령에서 이차성징을 보인 경우는 남아는 9세에서 2명(25.0%)이었고, 여아에서는 6세는 2명(14.3%), 7세는 6명(19.4%), 8세는 15명(39.6%), 9세는 4명(57.1%)이 이차성징을 보였다. 여아의 예측 평균 사춘기 발현 시기는 $9.11{\pm}1.86$세였다. 사춘기 발현 시기에 영향을 미치는 인자로 통계학적 유의성을 보인 것은 비만도, 패스트푸드 섭취빈도, 성장촉진제품 복용이었다. 비만도가 높을수록 패스트푸드 섭취빈도가 높을수록 사춘기 발현시기가 빨랐다. 성장관련제품을 복용하는 군이 사춘기 발현시기가 빨랐으나 비만도가 높아짐으로 인해 빨라진 것으로 나타났다. 결 론 : 본 연구의 결과 여아의 예측 평균 사춘기 발현 시기가 $9.11{\pm}1.86$세로서 국외의 결과와 유사함을 알 수 있었고, 사춘기 조기 발현에 영향을 미치는 인자는 비만도와 패스트푸드의 섭취 빈도였다.
