The International Physical Activity Questionnaire (IPAQ) was developed to measure health-enhancing physical activity in adult populations. This study explores the concurrent validity of a modified version of the long IPAQ (the IPAQ-A) for the assessment of physical activity among adolescents.
In total, 248 healthy adolescents, divided into one older and one younger age group (aged 15-17 years (N=188) and 12-14 years (N=60), respectively) from nine Healthy Lifestyle by Nutrition in Adolescence (HELENA) Study centres across Europe, voluntarily participated in the study. Data on total physical activity, as well as activities in different intensities derived from the IPAQ-A, were compared using Spearman's correlation coefficient and Bland-Altman analysis, with data from an accelerometer. Tertiles of total physical activity for the IPAQ-A and the accelerometer were compared using Kendall's tau-b.
For the older age group, significant correlations between the instruments were found for time spent walking, for moderate and vigorous activities as well as for total physical activity (Rs=0.17-0.30, P<0.05). No significant correlations were found for any of the variables studied in the younger age group. Kendall's tau-b showed low but significant correlations for tertiles of total physical activity (P<0.001).
The IPAQ-A has reasonable validity properties for assessing activities in different intensities and for total physical activity in healthy European adolescents aged 15-17 years. For adolescents aged 14 years and younger, the correlations were unsatisfactorily low and objective methodology, such as accelerometry, may be the appropriate alternative.
国际体力活动问卷（IPAQ）旨在测量成年人群中促进健康的体力活动。本研究探讨了长版IPAQ修改版（IPAQ-A）在评估青少年体力活动方面的同时效度。
来自欧洲九个青少年营养健康生活方式（HELENA）研究中心的248名健康青少年自愿参与了本研究，他们被分为一个年龄较大组和一个年龄较小组（分别为15 - 17岁（N = 188）和12 - 14岁（N = 60））。使用Spearman相关系数和Bland-Altman分析，将IPAQ-A得出的总体力活动数据以及不同强度活动的数据与加速度计数据进行比较。使用Kendall's tau-b比较IPAQ-A和加速度计的总体力活动三分位数。
对于年龄较大组，在步行时间、中等强度和剧烈强度活动以及总体力活动方面，两种测量工具之间存在显著相关性（Rs = 0.17 - 0.30，P < 0.05）。在年龄较小组中，所研究的任何变量均未发现显著相关性。Kendall's tau-b显示总体力活动三分位数之间存在低但显著的相关性（P < 0.001）。
IPAQ-A在评估15 - 17岁健康欧洲青少年的不同强度活动和总体力活动方面具有合理的效度特性。对于14岁及以下的青少年，相关性低得令人不满意，客观方法如加速度测量法可能是合适的替代方法。
