Abstract

Purpose : This study compared bone ages measured by the Greulich-Pyle (GP) and Tanner-Whitehouse 3 (TW3) methods and investigated the differences in predicted adult heights measured by Bayley-Pinneau (BP) and TW3 methods. Methods : Bone ages were assessed from left-wrist radiographs by two investigators, one for each GP and TW3 methods in 85 normal children, 30 precocious puberty girls, and 30 constitutional growth delay boys. The differences between the measured predicted adult heights using the BP and TW3 methods were compared in each group. Results : The bone age measured by the TW3 method was less than that by the GP method in normal children. The predicted adult heights measured by the two methods showed no significant difference in normal boys, while the predicted adult height measured by the TW3 method was higher than that by the BP method for normal girls ($156.4{\pm}4.7$ cm vs. $158.9{\pm}3.8$ cm, P<0.01) and for precocious puberty girls ($156.3{\pm}4.0$ cm vs. $159.3{\pm}4.2$ cm, P<0.01). In contrast, the predicted adult height was higher from the BP method than from the TW3 method in constitutional growth delay boys ($173.3{\pm}4.4$ cm vs. $169.7{\pm}3.2$ cm, P<0.01). Conclusion : There were significant differences in predicted adult heights between the BP and TW3 method in normal girls, precocious puberty girls, or constitutional growth delay boys. In precocious puberty and constitutional growth delay, the BP method might be preferred to predict adult height, but further studies on final adult height are needed.

목 적 : 정상 소아, 성조숙증, 체질성 성장 지연 소아를 대상으로 GP방법과 TW3방법에 의한 골연령을 비교하고 이를 이용하여 BP방법과 RUS 점수를 이용한 TW3방법의 예측 성인키를 구하여 상황에 따라 두 방법으로 구한 예측 성인키가 차이가 있는지를 알아보고자 하였다. 방 법 : 만성질환이나 약 복용력이 없고 병적인 저신장을 제외한 정상소아와 체질성 성장지연 남아, 그리고 성조숙증으로 진단된 여아를 대상으로 하였고 이들은 정상 소아는 85명, 체질성 성장 지연 남아 30명, 성조숙증으로 진단된 여아 30명이었으며 왼쪽 손과 손목 사진을 찍어 GP와 TW3방법으로 골연령을 측정하여 비교하고 이를 이용하여 BP법과 TW3 (RUS score)법을 이용하여 예측 성인키를 구하고 두 값의 차이를 비교하였다. 결 과 : GP방법과 TW3방법으로 구한 골연령의 경우 정상소아에서 남녀 모두 두 값에 유의한 차이를 보였고, 성 조숙증 여아의 경우 두 값의 차이는 없었으나 체질성 성장지연 남아에서는 두 값이 유의한 차이를 보였다. BP법과 TW3방법으로 구한 예측 성인키의 경우 정상소아에서 남아는 통계적으로 유의한 차이가 없었으나, 여아는 TW3법에 의한 예측키가 GP방법에 의한 예측키보다 큰 것으로 나타났다($156.4{\pm}4.7$ cm vs $158.9{\pm}3.8$ cm, P<0.01). 성조숙증 여아의 경우 BP법과 TW3법을 이용한 예측 성인키는 TW3법에 의한 예측키가 BP법을 이용한 예측키보다 크게 나타났다($156.3{\pm}4.0$ cm vs $159.3{\pm}4.2$ cm, P<0.01). 체질성 성장지연 남아에서 BP법과 TW3를 이용한 예측키는 BP법에 의한 것이 더 크게 나타났다($173.3{\pm}4.4$ cm vs $169.7{\pm}3.2$ cm, P<0.01). 결 론 : 정상 여아, 성조숙증 여아, 체질성 성장 지연 남아에서 BP법과 TW3법으로 구한 예측 성인키는 의미있는 차이를 보였다. 특히 성조숙증, 체질성 성장 지연 같은 특수 상황의 경우 BP법으로 구한 예측 성인키가 예후 판정에 더욱 유용할 것으로 생각되나 실제 성인키와의 비교 연구가 필요하다.
