简介：国际体力活动问卷（IPAQ）是为了衡量成年人的健康促进体力活动而开发的。本研究探讨了修改后的长期IPAQ版本的同时效度（IPAQ-A），用于评估青少年的身体活动。参与者和方法：总共有248名健康青少年，分为一个年龄较大的和一个年龄较小的组来自欧洲9个青少年营养健康生活方式（HELENA）研究中心的15-17岁（N 188）和12-14岁（N 60）志愿参加了这项研究。使用斯皮尔曼相关系数和Bland-Altman分析，将总体力活动数据以及来自IPAQ-A的不同强度活动数据与来自加速度计的数据进行比较。结果：在老年组中，IPAQ-A和加速计的步行时间、中等强度和剧烈活动时间以及总体力活动量均显著相关（Rs0.17 -0.30，P < 0.05）。在年轻年龄组中研究的任何变量都没有发现显着的相关性。结论：IPAQ-A对欧洲15-17岁健康青少年不同强度的活动和总体力活动的评价具有较好的效度。对于14岁及以下的青少年，相关性不令人满意的低和客观的方法，如加速度计，可能是适当的替代。
Introduction: 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.Participants and methods: 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.Results: 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).Conclusions: 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.
