摘　　要：为分析10~11岁儿童体力活动能量消耗与肥胖的相关性,该研究利用三轴加速度计测量60名10~11岁儿童连续7 d的体力活动数据,并分析其与BMI和腰臀比的相关性.结果显示1)男孩体力活动水平高于女孩,MVPA时间达标率在新政策促进下明显提升;2)超重/肥胖儿童体力活动水平低于体重正常儿童;3)儿童体力活动指标与肥胖程度指标相关性存在性别差异,表现为男孩和女孩METs值、MPA和MVPA与BMI和腰臀比均呈负相关,但仅男孩久坐时间与BMI和腰臀比呈正相关、LPA时间与BMI和腰臀比呈负相关;4)能量消耗值不适合用于反映体力活动水平和肥胖程度之间的关系.The study,to analyze the correlation between physical activity energy expenditure and obesity in children aged 10-11,adopts a triaxial accelerometer to measure the physical activity data of 60 children aged 10~11 for seven consecutive days and analyzes its correlation with BMI and waist-to-hip ratio.The results show as follows:1)The physical activity level in boys is higher than that of girls,and the daily average time in MVPA is significantly longer under the promotion of the new policy;2)The physical activity levels are lower in overweight/obese children than normal-weight children;3)There are gender differences in the correlation between physical activity indicators and obesity degree indicators in boys and girls,while sedentary time in boys i s positively correlated with BMI and waist-hip ratio,and LPA in boys is negatively correlated with BMI and waist-hip ratio;4)Energy expenditure is not suitable for reflecting the relationship between physical activity level and obesity.
