摘要

目的:双能x线吸收仪(DXA)被认为是流行病学研究中肥胖测量的参考方法。本研究的目的是评估性别、年龄和体质对韩国儿童和青少年体重指数(BMI)和DXA导出的肥胖指数之间关系的影响。方法:采用2009年至2011年韩国国家健康与营养调查(KNHANES)中具有全国代表性的样本,将韩国儿童和青少年的BMI与DXA测定的肥胖指数(脂肪质量指数,FMI和体脂百分比,PBF)进行比较。随后根据性别、年龄组(10-12.9岁的儿童、13-15.9岁的青少年早期和16-18.9岁的青少年晚期)和BMI水平(年龄和性别<或≥85百分位)排除相关性。结果:在1919年(1024名男孩)韩国儿童和青少年中,BMI与FMI的相关性比PBF更强(r = 0797和r = 0.519,分别为所有研究对象,P < 0.05),跨越所有年龄组、性别和体质。结论:在韩国儿童和青少年中,BMI与FMI的相关性高于PBF。

RELATIONSHIP BETWEEN BODY MASS INDEX (BMI) AND DUAL-ENERGY X- RAY ABSORPTIOMETRY (DXA) DETERMINED ADIPOSITY INDICES IN KOREAN CHILDREN AND ADOLESCENTS; THE INFLUENCE OF GENDER, AGE GROUPS, AND PHYSIQUE
Aim: Dual-energy X-ray absorptiometry (DXA) is considered a reference method for adiposity measurements in epidemiologic studies. The purpose of this study was to evaluate the influence of gender, age, and physique in the relationship between body mass index (BMI) and DXA derived adiposity indices for Korean children and adolescents. Methods: Using a nationally representative sample taken from the Korean National Health and Nutrition Examination Survey (KNHANES), 2009 to 2011, BMI of Korean children and adolescents was compared with DXA determined adiposity indices (fat mass index, FMI and percentage body fat, PBF). The correlation was subsequently evacuated according to the genders, age groups (children aged 10-12.9 yrs, early adolescents aged 13-15.9 yrs, and late adolescents aged 16-18.9 yrs.) and BMI level (< or ≥85th percentile for age and sex). Results: In 1919 (1024 boys) Korean children and adolescents, BMI was more strongly correlated with FMI than PBF (r = 0797 and r = 0.519, respectively all study subjects, P < 0.05), across all age groups, gender, and physiques. Conclusions: BMI is more highly correlated with FMI than PBF in Korean children and adolescents.
