Abstract

The aim of this study was to investigate the issue in obese children with a high probability of leading to precocious puberty for they have more advanced skeletal maturation compared to normal children in order to contribute to the health of obese children by identifying the relationship between physique and physical fitness according to their skeletal maturation. A total of 243 obese children between the ages of 10-13 were enrolled as subjects, and the skeletal maturation, which symbolize indicators of biological maturation, were evaluated by using the TW3 method after hand-wrist radiographs, thus classified the skeletal maturation level into retarded group(n=70), normal group(n=128), and advanced group(n=45). A stadiometer and InBody 270 (Biospace, Korea) were used to measure 3 components in physique. A total of 7 components in physical fitness, which included muscular strength, muscular endurance, flexibility, power, cardiovascular endurance, balance, agility, were measured as well. Descriptive statistics and one-way variable analysis (ANOVA) were conducted for data processing using SPSS 25.0, and Duncan's multiple-range method was used for post hoc analysis; and it was considered significant at the level of P< .05. Analysis results of this study may be summarized as follow. First, height and weight in physique factors according to the skeletal maturation between the retarded, normal, and advanced groups in males and females were highly significant. Second, physical fitness comparison according to the skeletal maturation in males were statistically significant in muscular strength, power, and agility whereas muscular strength and balance were statistically significant in females.

본 연구는 비만아동의 골격성숙도가 정상 아동들 보다 높고 성조숙증으로 이어질 확률이 높은 것을 문제점으로 삼아 비만아동의 골격성숙도에 따른 체격 및 체력의 관계를 규명함으로써 비만아동의 건강증진에 기여하는 것을 목적으로 하였다. 연구대상은 10세부터 13세의 비만아동 총 243명을 대상으로 생물학적 성숙지표를 나타내는 골격성숙도는 X-ray 촬영 후 TW3 방법을 이용하여 평가하였고, 골격성숙도에 따른 미숙집단(n=70), 보통집단(n=128), 조숙집단(n=45)으로 나누었다. 체격은 신장계, InBody 270(Biospace, Korea)을 이용하여 3개 항목을 측정하였다. 체력측정은 총 7개 항목으로 근력, 근지구력, 유연성, 순발력, 심폐지구력, 평형성, 민첩성을 측정하였다. 자료처리는 SPSS 25.0을 사용하여 기술통계, 일원변량분석(ANOVA)을 실시하였고, 사후검정은 Duncan's multiple range 방법을 이용하였으며, P< .05 수준에서 유의한 것으로 간주하였다. 본 연구의 결과는 다음과 같다. 첫째, 골격성숙도에 따른 신장과 체중의 체격 요인에서 남자와 여자 미숙집단, 보통집단, 조숙집단 간 통계적으로 매우 유의한 차이를 보였다. 둘째, 골격성숙도에 따른 체력 비교에서 남자의 경우 근력, 순발력, 민첩성에서 유의한 차이가 나타났으며, 여자의 경우 근력, 평형성에서 유의한 차이가 나타났다.
