The purpose of this study was to examine the relationship between perceived physical competence (PPC), actual motor competence (MC) and body mass index (BMI) in young children.
We assessed MC (Test of Gross Motor Development - 2nd Edition), PPC (Pictorial Scale of Perceived Competence and Social Acceptance) and BMI (CDC calculator) of 178 young children ages 4-7 years.
The linear regression model for the overall sample showed that BMI was a better predictor of PPC than MC. Also, obese children had lower PPC, but showed no differences in MC compared with leaner peers.
PPC of young obese children was lower than their leaner counterparts, yet their MC was similar. That outcome draws attention to the importance of promoting positive PPC in young children.
本研究的目的是探讨幼儿的感知身体能力（PPC）、实际运动能力（MC）与体重指数（BMI）之间的关系。
我们评估了178名4至7岁幼儿的MC（《粗大运动发展测试-第二版》）、PPC（《感知能力和社会接纳度图片量表》）和BMI（疾病控制与预防中心计算器）。
总体样本的线性回归模型显示，与MC相比，BMI是PPC更好的预测指标。此外，肥胖儿童的PPC较低，但与较瘦的同龄人相比，其MC没有差异。
肥胖幼儿的PPC低于较瘦的同龄人，但其MC相似。这一结果凸显了促进幼儿积极PPC的重要性。
