This study evaluates the Quantification de L'Activite Physique en Altitude chez les Enfants (QAPACE) supervised self-administered questionnaire reproducibility and validity on the estimation of the mean daily energy expenditure (DEE) on Bogotá's schoolchildren. The comprehension was assessed on 324 students, whereas the reproducibility was studied on a different random sample of 162 who were exposed twice to it. Reproducibility was assessed using both the Bland-Altman plot and the intra-class correlation coefficient (ICC). The validity was studied in a sample of 18 girls and 18 boys randomly selected, which completed the test - re-test study. The DEE derived from the questionnaire was compared with the laboratory measurement results of the peak oxygen uptake (Peak VO2) from ergo-spirometry and Leger Test. The reproducibility ICC was 0.96 (95% C.I. 0.95-0.97); by age categories 8-10, 0.94 (0.89-0. 97); 11-13, 0.98 (0.96- 0.99); 14-16, 0.95 (0.91-0.98). The ICC between mean TEE as estimated by the questionnaire and the direct and indirect Peak VO2 was 0.76 (0.66) (p<0.01); by age categories, 8-10, 11-13, and 14-16 were 0.89 (0.87), 0.76 (0.78) and 0.88 (0.80) respectively. The QAPACE questionnaire is reproducible and valid for estimating PA and showed a high correlation with the Peak VO2 uptake. Key pointsThe presence of a supervisor, the limited size of the group with the possibility of answering to their questions could explain the high reproducibility for this questionnaire.No study in the literature had directly addressed the issue of estimating a yearly average PA including school and vacation period.A two step procedure, in the population of schoolchildren of Bogotá, gives confidence in the use of the QAPACE questionnaire in a large epidemiological survey in related populations.
本研究评估了 Quantification de L'Activite Physique en Altitude chez les Enfants（QAPACE）自我监督问卷在估算波哥大儿童平均日常能量支出（DEE）方面的可重复性和有效性。324 名学生进行了理解评估，而 162 名不同的随机样本进行了两次暴露以评估可重复性。使用 Bland-Altman 图和组内相关系数（ICC）评估了可重复性。在随机选择的 18 名女孩和 18 名男孩样本中研究了有效性，该样本完成了测试-重测研究。从问卷中得出的 DEE 与来自 ergospirometry 和 Leger Test 的峰值摄氧量（Peak VO2）的实验室测量结果进行了比较。可重复性 ICC 为 0.96（95%CI 0.95-0.97）；按年龄类别 8-10 岁、0.94（0.89-0.97）、11-13 岁、0.98（0.96-0.99）、14-16 岁、0.95（0.91-0.98）。问卷估计的平均 TEE 与直接和间接 Peak VO2 之间的 ICC 为 0.76（0.66）（p<0.01）；按年龄类别，8-10 岁、11-13 岁和 14-16 岁分别为 0.89（0.87）、0.76（0.78）和 0.88（0.80）。QAPACE 问卷可重复且可有效评估 PA，与 Peak VO2 摄取量具有高度相关性。关键点有监督者的存在，小组规模有限，有可能回答他们的问题，这可以解释该问卷的高可重复性。文献中没有研究直接解决估计包括学校和假期在内的全年平均 PA 的问题。在波哥大儿童人群中进行的两步程序使我们有信心在相关人群中进行大规模的流行病学调查中使用 QAPACE 问卷。
