【摘要】：目的:通过分析学龄前儿童体力活动水平与身体生长指标的关联性,探讨体力活动对学龄前儿童身体生长的影响。方法:募集上海市学龄前儿童224名,采用三轴加速度传感器测量其日常体力活动水平,并借助WHO Anthro与WHO Anthro Plus软件计算年龄别身高Z值(HAZ)、年龄别体重Z值(WAZ)和年龄别BMI Z值(BAZ)等身体生长指标结果,利用线性回归模型探讨体力活动与身体生长指标的关联性。结果:在受试男童中,中大强度体力活动(MVPA)与体重(β=0.173,P=0.029)、WAZ(β=0.217,P=0.015)均呈显著正相关;女童MVPA与身高(β=0.208,P=0.011)、HAZ(β=0.262,P=0.008)均呈显著正相关,TPA与HAZ(β=0.195,P=0.0498)呈显著正相关。结论:体力活动尤其是MVPA与学龄前儿童身体生长呈显著正相关,应着重关注如何提高学龄前儿童日常MVPA水平。
[Abstract]:Objective: to explore the effect of physical activity on preschool children's physical growth by analyzing the correlation between physical activity level and body growth index. Methods: 224 preschool children in Shanghai were recruited and their daily physical activities were measured by triaxial accelerometer. With the help of WHO Anthro and WHO Anthro Plus software, the results of body growth indexes such as age, height, (HAZ), age, weight, (WAZ) and BMI Z (BAZ) were calculated. The relationship between physical activity and body growth index was discussed by using linear regression model. Results: there was a significant positive correlation between (MVPA) and body weight (尾 = 0.173), WAZ (尾 = 0.217P0. 015), MVPA and height (尾 = 0. 208), HAZ (尾 = 0. 262), HAZ (尾 = 0. 262 P0. 008), and significant positive correlation between TPA and HAZ (尾 = 0. 195 P0. 0498) in the male children with moderate and high intensity physical activity (尾 = 0. 173 P0. 029), WAZ (尾 = 0. 2177P0. 015), while in girls, there was a significant positive correlation between MVPA and height (尾 = 0. 208), HAZ (尾 = 0. 262), HAZ (尾 = 0. 262 P0. 008). Conclusion: physical activity, especially MVPA, is positively correlated with preschool children's physical growth. Attention should be paid to how to improve the daily MVPA level of preschool children.
