Purpose: Precocious puberty is defined as breast development before the age of 8 years in girls. The present study aimed to reveal the diagnosis of Korean girls referred for precocious puberty and to compare the constitutional and endocrinological features among diagnosis groups. Methods: The present study used a retrospective chart review of 988 Korean girls who had visited a pediatric endocrinology clinic from 2006 to 2010 for the evaluation of precocious puberty. Study groups comprised fast puberty, true precocious puberty (PP), pseudo PP, premature thelarche, and control. We determined the height standard deviation score (HSDS), weight standard deviation score (WSDS), and body mass index standard deviation score (BMISDS) of each group using the published 2007 Korean growth charts. Hormone tests were performed at our outpatient clinic. Results: The PP groups comprised fast puberty (67%), premature thelarche (17%), true PP (15%), and pseudo PP (1%). Advanced bone age and levels of estradiol, basal luteinizing hormone (LH), and peak LH after gonadotropin-releasing hormone stimulation testing were significantly high in the fast puberty and true PP groups compared with the control group. HSDS, WSDS, and BMISDS were significantly higher in the true PP group than in the control group (P<0.05). Conclusion: The frequent causes of PP were found to be fast puberty, true PP, and premature thelarche. Furthermore, BMISDS were significantly elevated in the true PP group. Therefore, we emphasize the need for regular follow-up of girls who are heavier or taller than others in the same age group.

본 연구의 목적은 한국 소아청소년 표준 골연령 도표를 이용하여 평가한 SMI 및 MP3 단계별 골연령을 조사하여 최대 성장기에 해당하는 단계를 알아보고, 이를 통해 성장 중인 부정교합 환자의 치료 계획 수립, 치료방법 및 시기에 중요한 영향을 미치는 성장 발육평가 자료를 제공하고자 함이다. 이대목동병원 소아청소년과에 내원한 363명의 환자의 수완부 방사선 사진에서 한국 소아 청소년의 표준 골연령 도표를 바탕으로 영상의학과 의사에 의해 판정된 골연령을 조사하였다. 동일한 방사선 사진에서 평가된 SMI 및 MP3 단계에 따른 평균 골연령을 산출하였다. 본 연구 결과 사춘기 최대 성장기가 남아에서는 SMI 4 - 5단계 및 MP3 FG - G단계, 여아에서는 SMI 3 - 4단계 및 MP3 F - FG단계에서 나타남을 확인하였다.
