3~6岁儿童基本运动能力评估量表中国常模研究

Chinese norm of General Physical Activity Scale for children aged 3 to 6

目的建立3~6岁儿童基本运动能力评估量表的中国常模,探讨其常模界值,为临床运用提供一项实用的评估工具。方法2020年8月—2021年5月,采取分层整群抽样的方法,使用3~6岁儿童基本运动能力评估量表获得全国六大行政区8个城市3~6岁儿童1616例,统计分析量表全部6个维度的常模得分和界值点。结果量表各维度得分比较,差异具有统计学意义(F=10.96~117.77,P<0.001)。量表总分ROC曲线下面积为0.937,95%CI为0.916~0.957。最大约登指数(YI)=0.74,其对应的量表总分在常模中位于第17百分位(P_(17)),常模的灵敏度为0.871,特异度为0.864。当分别以P_(15)(76)和P_(20)(80)为界值点时,YI分别为0.69和0.72,灵敏度和特异度皆>0.8。结论本研究常模样本具有良好的代表性,制定的界值点适当,对评估3~6岁儿童基本运动能力具有很好的临床运用价值,可推广运用。

Objective To establish Chinese norm of General Physical Activity Scale for children aged 3 to 6,and to explore its cut-off score for the norm,thus to provide a practical tool for clinical application.Methods From August 2020 to May 2021,a stratified cluster sampling approach was utilized to recruit 1616 children aged 3 to 6 years from eight cities in six major administrative regions of China.The norm distribution and scores were analyzed,and its cut-off score was discussed.Results The scores of each dimension was significantly different among eight cities(F=10.964-117.766,P<0.001).The area under the receiver operating characteristic curve of the total score of the scale is 0.937(95%CI:0.916-0.957).The maximum Yuden Index(YI)was 0.74,and the corresponding total score was in the 17th percentile(P_(17)) in the norm,with the sensitivity of 0.871 and specificity of 0.864.When P_(15)(76) and P_(20)(80) were taken as the threshold point,the corresponding YI was 0.69 and 0.72,respectively,and the sensitivity and specificity were both above 0.8.Conclusions The norm sample of this study is representative,and the cut-off score is appropriate,which can be popularized and applied in clinic practice.
