目的探讨体育活动方式和睡眠时间对学龄前儿童生长发育和身体组成的影响。目的是(1)描述身体活动成分、睡眠、总能量消耗（TEE）和身体大小和组成之间的横断面关联；(2)确定身体活动成分、睡眠和TEE是否能预测健康学龄前儿童1年的体型和成分变化。方法基线时测量人体测量、体成分、加速度、双标记水TEE；1年后复查人体测量和身体成分（n=111）。结果横截面上，久坐活动与体重和无脂质量（FFM）呈正相关（P = 0.009 ~ 0.047），中等剧烈运动（MVPA）与脂肪质量百分比（FM）呈负相关（P = 0.015）。TEE和活动能消耗（AEE）与体重、体质量指数（BMI）、FFM和FM呈正相关（P = 0.0001 ~ 0.046）。前瞻性地，TEE、AEE、体力活动水平和MVPA与BMI （P = 0.0001-0.051）和FFM （P = 0.0001-0.037）呈正相关，但与FM百分比无关，而不与久坐活动呈正相关。睡眠时间与调频变化（P = 0.005）和调频百分比（P = 0.006）呈负相关。结论MVPA、TEE、AEE和体力活动水平可促进FFM的正常生长和增加，而睡眠时间与学龄前儿童肥胖的变化呈负相关。
ObjectiveThe impact of physical activity patterns and sleep duration on growth and body composition of preschool-aged children remains unresolved. Aims were (1) to delineate cross-sectional associations among physical activity components, sleep, total energy expenditure (TEE), and body size and composition; and (2) to determine whether physical activity components, sleep, and TEE predict 1-year changes in body size and composition in healthy preschool-aged children.MethodsAnthropometry, body composition, accelerometry, and TEE by doubly labeled water were measured at baseline; anthropometry and body composition were repeated 1 year later (n=111).ResultsCross-sectionally, positive associations between sedentary activity and weight and fat-free mass (FFM) (P = 0.009-0.047), and a negative association between moderate-vigorous physical activity (MVPA) and percent fat mass (FM) (P = 0.015) were observed. TEE and activity energy expenditure (AEE) were positively associated with weight, body mass index (BMI), FFM, and FM (P = 0.0001-0.046). Prospectively, TEE, AEE, physical activity level, and MVPA, but not sedentary activity, were positively associated with changes in BMI (P = 0.0001-0.051) and FFM (P = 0.0001-0.037), but not percent FM. Sleep duration inversely predicted changes in FM (P = 0.005) and percent FM (P = 0.006).ConclusionsProspectively, MVPA, TEE, AEE, and physical activity level promote normal growth and accretion of FFM, whereas sleep duration inversely predicts changes in adiposity in preschool-aged children.
