目的
研究肥胖和非肥胖儿童安静时饮食组成、身体组成和大量营养素氧化之间的关系。
设计
脂肪摄入、肥胖和吸收后大量营养素氧化率的横断面研究。
科目
82名青春期前（年龄：9.1 ± 1.1岁）儿童，30名肥胖（FM = 32.6 ± 6.1%）和52名非肥胖（FM = 15.6 ± 5.1%）。
测量
皮下皮褶厚度用于身体组成，饮食史用于能量和营养摄入，间接热量测定用于静息代谢率（RMR）和RQ测量。
结果
肥胖和非肥胖儿童的能量摄入（EI）相当。通过ANCOVA校正RMR，使用RMR作为协变量，肥胖儿童的EI显著低于非肥胖儿童，表明体力活动减弱或系统性低估EI。蛋白质和碳水化合物的摄入量表示为总能量摄入的百分比（%EI）在两组中没有显着差异。通过ANCOVA，无论是未校正还是校正RMR后，肥胖组的脂质摄入量（%EI）均略高于非肥胖组，但具有显著性。肥胖儿童的吸收后RQ显著低于非肥胖儿童。在总组中，%FM与脂质摄入量（%EI）弱但显著相关。
结论
肥胖的青春期前儿童有较高的相对脂肪摄入量比非肥胖儿童和他们的FM与这一因素有关。肥胖儿童较低的吸收后RQ可能表明通过增强脂肪氧化达到脂肪平衡的代偿机制。
OBJECTIVE
To investigate the relationships between diet composition, body composition, and macronutrient oxidation at rest in obese and non-obese children.
DESIGN
Cross-sectional study on fat intake, adiposity and postabsorptive macronutrients oxidation rates.
SUBJECTS
82 prepubertal (age: 9.1 +/- 1.1 y) children, 30 obese (FM = 32.6 +/- 6.1%) and 52 non-obese (FM = 15.6 +/- 5.1%).
MEASUREMENTS
Subcutaneous skinfold thickness for body composition, diet history for energy and nutrient intake, indirect calorimetry for resting metabolic rate (RMR) and RQ measurement.
RESULTS
Energy intake (EI) was comparable in obese and non-obese children. Adjusted for RMR by ANCOVA, using RMR as the covariate, EI was significantly lower in obese than in non-obese children indicating either a blunted physical activity or a systematic underestimation of EI. Protein and carbohydrate intakes expressed as a percentage of total energy intake (%EI) were not significantly different in the two groups. Lipid intake (%EI) was slightly but significantly higher in the obese than in the non-obese group either unadjusted or adjusted for RMR by ANCOVA. The postabsorptive RQ was significantly lower in obese than in non-obese children. In the total group, %FM was weakly but significantly correlated to lipid intake (%EI).
CONCLUSION
Obese prepubertal children have a higher relative fat intake than non-obese children and their FM is associated with this factor. The lower postabsorptive RQ of obese children may indicate a compensatory mechanism to achieve fat equilibrium by enhanced fat oxidation.
