BACKGROUND/AIM: Little is known about the measurement properties of the self-administered Global Physical Activity Questionnaire (GPAQ) in Europe. The aim was to validate the self-administered GPAQ against accelerometry in Switzerland in German, French and Italian.
Participants of this cross-sectional study were recruited among members of the Swiss Food Panel (German-speaking and French-speaking samples) and as a convenience sample (Italian-speaking sample). They completed the GPAQ and wore an Actigraph GT3X+ accelerometer during 7 days in 2014/2015. GPAQ and accelerometer data on total physical activity and different intensities, as well as sitting time, were compared using Spearman correlations and Bland-Altman plots.
Complete data were available for 354 participants (50.6% women, mean age: 47.0 years) on physical activity, and for 366 on sitting time. Correlations were highest for vigorous physical activity (r=0.46) and sitting time (r=0.47). A significant sex difference was apparent for vigorous physical activity (men: r=0.35 vs women: r=0.55; p=0.02). Some age differences were present especially for total physical activity, with the lowest correlations found for those aged 60+ years. The correlation for sitting time was significantly higher in the youngest age group (r=0.61) compared with the middle (r=0.38, p=0.01) and the oldest age groups (r=0.37, p=0.03). Total physical activity was 2.8 times higher according to the GPAQ than to accelerometer data.
The self-administered version of the GPAQ showed fair-to-moderate validity in the three languages tested, both for men and women and individuals aged ≤60 years. For older individuals, a careful interpretation of total physical activity is required.
背景/目的:在欧洲,关于自行填写的全球体力活动问卷(GPAQ)的测量属性知之甚少。目的是在瑞士对德语、法语和意大利语版本的自行填写的GPAQ与加速度计进行效度验证。
本横断面研究的参与者招募自瑞士食品小组的成员(德语和法语样本)以及一个便利样本(意大利语样本)。他们在2014/2015年的7天内完成了GPAQ并佩戴了Actigraph GT3X +加速度计。使用Spearman相关性分析和Bland-Altman图比较了GPAQ和加速度计关于总体力活动、不同强度以及久坐时间的数据。
共有354名参与者(50.6%为女性,平均年龄:47.0岁)提供了关于体力活动的完整数据,366名参与者提供了关于久坐时间的完整数据。剧烈体力活动(r = 0.46)和久坐时间(r = 0.47)的相关性最高。剧烈体力活动存在显著的性别差异(男性:r = 0.35,女性:r = 0.55;p = 0.02)。存在一些年龄差异,尤其是总体力活动方面,60岁及以上人群的相关性最低。最年轻年龄组的久坐时间相关性(r = 0.61)显著高于中年组(r = 0.38,p = 0.01)和老年组(r = 0.37,p = 0.03)。根据GPAQ得出的总体力活动比加速度计数据高2.8倍。
自行填写版本的GPAQ在测试的三种语言中,对男性和女性以及60岁及以下个体显示出中等至良好的效度。对于年龄较大的个体,需要谨慎解读总体力活动数据。
