目的：探讨儿童体力活动、膳食摄入和身体成分之间的关系。设计：对86名法国10岁健康儿童的身体活动、营养摄入和身体成分进行横断面研究。此外，从10个月开始，可以获得生长参数和营养摄入量。测量:10岁时的身体活动水平（使用过去一年的有效活动问卷）、营养摄入（饮食史法）、人体测量值（体重、身高、臂围、三头肌和肩胛下皮肤褶皱、身体质量指数（BMI）、根据这些测量值计算的手臂肌肉和手臂脂肪面积）。这些儿童在10个月时和从2岁起每隔2年记录一次人体测量值和营养摄入。10岁时，活跃儿童摄入的能量明显高于不活跃儿童，主要是由于早餐和下午摄入的能量较高。这一较高的能量摄入是由于碳水化合物的消耗增加（281克对246克；占总能量的49.6%对47.4%）。即使两组的脂肪摄入量相似（90克对84克，P = 0.09），但运动儿童的脂肪摄入量比例更高（35.4%对37.4%,P = 0.04）。蛋白质含量差异无统计学意义（14.9% vs 15.3%; P = 0.33）。尽管运动组的能量摄入较高，但运动组和不运动组的儿童在10岁时的BMI相似。然而，他们的身体组成有显著差异：运动组的儿童无脂肪质量比例较高，手臂测量的脂肪质量比例较低，并且他们的肥胖反弹较晚。肥胖程度与看电视和玩电子游戏的时间呈正相关。结论：体育活动与改善身体成分和生长模式有关。这种关联可能与营养变化有关：活跃的儿童通过增加碳水化合物消耗更多的能量，从而减少他们饮食中的相对脂肪含量。这些结果为鼓励儿童时期的体育活动提供了支持。
OBJECTIVES: To investigate the relationships between physical activity, dietary intake and body composition in children.DESIGN: A cross-sectional study on physical activity, nutritional intakes and body composition conducted in 86 healthy 10 y old French children. In addition, growth parameters and nutritional intakes were available from the age of 10 months.MEASUREMENTS: Physical activity level (using a validated activity questionnaire over the past year), nutritional intake (dietary history method), anthropometric measurements (body weight, height, arm circumference, triceps and subscapular skinfolds, Body Mass index (BMI), arm muscle and arm fat areas calculated from these measurements) at the age of 10 y. Anthropometric measurements and nutritional intakes were recorded in the same children at the age of 10 months and every 2 y from the age of 2 y.RESULTS: At the age of 10 y, active children ingested significantly more energy than less active children, mostly doe to higher energy intake at breakfast and in the afternoon. This higher energy intake was accounted for by increased consumption of carbohydrates (281 g vs 246 g; 49.6% vs 47.4% of total energy). Even if the amounts of fat consumed were similar in both groups (90 g vs 84 g; P = 0.09), the percentage of fat intake was tower in active children (35.4% vs 37.4%; P = 0.04). The percentage of protein was not different (14.9% vs 15.3%; P = 0.33). In spite of a higher energy intake in the active group, active and less active children had similar BMI at the age of 10 y. However, their body composition differed significantly: active children had a higher proportion of fat-free mass, a lower proportion of fat-mass as measured in the arm and they had a later adiposity rebound. Fatness was significantly and positively associated with the time spent watching television and video games.CONCLUSIONS: Physical activity was associated with improved body composition and growth pattern. This association may be related to nutritional changes: active children consumed more energy by increasing carbohydrate, thus reducing the relative fat content of their diet. These results provide support to encourage physical activity during childhood.
