Abstract

BACKGROUND

The Physical Activity Questionnaire for Children (PAQ-C) is widely used to assess physical activity in populations; however, there is a lack of information about the psychometric properties (validity and reliability) and about the PAQ-C score meaning in populations from low-middle income countries.

AIMS

The aim of this study is to evaluate the reliability and validity of PAQ-C and to determine the cut-point values of PAQ-C using accelerometry as a reference in a group of Moroccan children.

METHODS

In a sample of 171 children and adolescents aged 8 to 14 years, physical activity was assessed with the GT3X + accelerometer and the PAQ-C. PAQ-C was administered for a second time (retest) after 1 week for a subsample (n = 73). Reliability was analyzed by intraclass correlation coefficient (ICC). The PAQ-C was compared against count per minute CPM and moderate to vigorous intensity PA (MVPA) obtained by accelerometry. Receiver operating curve analyses were performed to assess the performance of PAQ-C in identifying MVPA as measured by accelerometry (reference method).

RESULTS

Test-retest reliability was poor with an ICC = (0.48 [0.27; 0.63] for the whole sample, while for the ≥11 year group, the intra-class correlation coefficient was moderate (0.71 [0.42; 0.86]. PAQ-C scores were significantly related to accelerometry-derived metrics of physical activity, CPM (R = 0.29, P < 0.001) and MVPA (R = 0.26, P < 0.001). For the age group ≥11 years, the associations between PAQ-C Scores and CPM and MVPA were stronger, respectively, R = 0.37 (P < 0.001), R = 0.38 (P < 0.0001). We identified that a PAQ-C Score cut-point of 2.33 (95%CI [0.43-0.68]) discriminated adequately between those who met physical activity guidelines and those that did not in the overall sample.

CONCLUSIONS

The PAQ-C is valid and useful to assess population level physical activity in those ≥11 years in Morocco and so might be helpful in population surveillance of physical activity in Moroccan adolescents.

摘要

背景

儿童体力活动问卷（PAQ-C）广泛用于评估人群中的体力活动；然而，在中低收入国家的人群中，关于 PAQ-C 的心理测量学特性（有效性和可靠性）以及 PAQ-C 评分的含义，我们知之甚少。

目的

本研究旨在评估 PAQ-C 的可靠性和有效性，并使用加速度计作为参考，确定摩洛哥儿童群体中 PAQ-C 的切点值。

方法

在 171 名 8 至 14 岁的儿童和青少年样本中，使用 GT3X+加速度计和 PAQ-C 评估体力活动。PAQ-C 在一周后对小样本（n=73）进行了第二次（重测）测试。通过组内相关系数（ICC）分析可靠性。PAQ-C 与加速度计测量的每分钟计数（CPM）和中等到剧烈强度体力活动（MVPA）进行比较。进行受试者工作特征曲线分析，以评估 PAQ-C 在识别加速度计测量的 MVPA（参考方法）方面的性能。

结果

整个样本的重测信度较差，ICC=（0.48[0.27；0.63]，而≥11 岁组的组内相关系数为中度（0.71[0.42；0.86]）。PAQ-C 评分与加速度计衍生的体力活动指标，CPM（R=0.29，P<0.001）和 MVPA（R=0.26，P<0.001）显著相关。对于≥11 岁的年龄组，PAQ-C 评分与 CPM 和 MVPA 之间的相关性更强，分别为 R=0.37（P<0.001），R=0.38（P<0.0001）。我们发现，PAQ-C 评分 2.33（95%CI[0.43-0.68]）的切点值可在总体样本中充分区分符合体力活动指南和不符合体力活动指南的人群。
