The present study aimed to determine a cut-off value following the filling in of a questionnaire (PAQ-C-It) to identify active Italian children. One-hundred-twenty-nine primary school children (5 Piedmont schools; 47.3% female; mean age = 10 ± 1 years) wore an accelerometer (Actigraph wGT3X-BT) to objectively quantify individual moderate-to-vigorous physical activity during one week. Afterwards, the PAQ-C-It was filled in by participants. A ROC curve procedure was applied to obtain an active/non-active cut-off point. Spearman’s correlation coefficient was also applied to establish the relationship between the two parameters. According to the ROC analysis, the PAQ-C-It cut-off point value is identifiable at >2.75 to indicate active children (area under the curve = 0.62; standard error = 0.05; p = 0.025; coefficient intervals = 0.518−0.716; sensitivity = 0.592, specificity = 0.382), determining that 65 participants (55%) were non-active (mean PAQ-C-It value = 2.3 ± 0.4; active mean PAQ-C-It value = 3.3 ± 0.4). Spearman’s correlation coefficient results were significant but with a small effect size (rho = 0.214; p = 0.008). In conclusion, the present results suggest that the PAQ-C-It can be cautiously used as tool to practically classify active Italian children because of a non-solid relationship between respective accelerometer data and MVPA daily data.
本研究旨在确定填写一份问卷（PAQ-C-It）后的临界值，以识别活跃的意大利儿童。129名小学生（来自皮埃蒙特的5所学校；47.3%为女生；平均年龄 = 10±1岁）佩戴了加速度计（Actigraph wGT3X-BT），以客观量化一周内个人的中度至剧烈身体活动。之后，参与者填写了PAQ-C-It问卷。应用ROC曲线程序以获得活跃/不活跃的临界点。还应用了斯皮尔曼相关系数来建立两个参数之间的关系。根据ROC分析，PAQ-C-It的临界点值可确定为>2.75，以表明活跃儿童（曲线下面积 = 0.62；标准误差 = 0.05；p = 0.025；系数区间 = 0.518−0.716；灵敏度 = 0.592，特异性 = 0.382），确定65名参与者（55%）不活跃（PAQ-C-It平均值得分 = 2.3±0.4；活跃组PAQ-C-It平均值得分 = 3.3±0.4）。斯皮尔曼相关系数结果显著，但效应量较小（rho = 0.214；p = 0.008）。总之，本研究结果表明，由于加速度计数据与每日中度至剧烈身体活动数据之间的关系不稳固，PAQ-C-It问卷可谨慎用作实际分类活跃意大利儿童的工具。
