BACKGROUND
Body fat percentage (BF%), fat mass index (FMI), and lean body mass index (LBMI) are often used to evaluate the nutritional status of children. Until now, no pediatric FMI reference centiles are applicable for GE Healthcare Lunar DXA systems. The aim of the study was to generate age-specific BF%, FMI, and LBMI references centiles for GE Healthcare Lunar DXA systems.
METHODOLOGY
Published values from the National Health and Nutrition Examination Survey 1999-2004 (age 8-20 years) were used to generate the reference centiles for the non-Hispanic black, non-Hispanic white, and Mexican American NHANES population. The LMS and LMSP methods were used to generate the reference centiles.
RESULTS
Data of 2433 non-Hispanic black children (972 females), 2026 non-Hispanic white children (873 females), and 2547 Mexican American children (1010 females) were eligible.
CONCLUSIONS
We presented age-specific reference centiles for BF%, FMI, and LBMI for children and adolescents which were ethnicity specific (non-Hispanic black, non-Hispanic white, and Mexican American) and directly applicable to Prodigy and iDXA GE Healthcare Lunar systems with software version 14.0. We proposed the use of BF%, FMI, and LBMI together to evaluate nutritional status in children.
背景
体脂肪百分比（BF%）、脂肪质量指数（FMI）和瘦体重指数（LBMI）常用于评估儿童的营养状况。到目前为止，还没有适用于 GE Healthcare Lunar DXA 系统的儿科 FMI 参考百分位数。本研究旨在为 GE Healthcare Lunar DXA 系统生成特定年龄的 BF%、FMI 和 LBMI 参考百分位数。
方法
使用来自 1999-2004 年全国健康和营养检查调查（年龄 8-20 岁）的公布值，为非西班牙裔黑人、非西班牙裔白人和墨西哥裔美国人 NHANES 人群生成参考百分位数。使用 LMS 和 LMSP 方法生成参考百分位数。
结果
符合条件的非西班牙裔黑人儿童数据为 2433 例（972 例女性），非西班牙裔白人和墨西哥裔美国儿童数据分别为 2026 例（873 例女性）和 2547 例（1010 例女性）。
结论
我们为儿童和青少年提供了特定年龄的 BF%、FMI 和 LBMI 参考百分位数，这些百分位数是特定族裔（非西班牙裔黑人、非西班牙裔白人和墨西哥裔美国人）的，并且可以直接应用于 Prodigy 和 iDXA GE Healthcare Lunar 系统，软件版本为 14.0。我们建议使用 BF%、FMI 和 LBMI 来评估儿童的营养状况。
