The International Physical Activity Questionnaire (IPAQ) is widely used to assess physical activity (PA), but its validity compared to device-measured PA data in patients with Femoroacetabular Impingement Syndrome (FAIS) and Acetabular Dysplasia (AD) remains underexplored. We evaluated the convergent and divergent aspects of construct validity of self-reported PA via the IPAQ versus accelerometry data in patients with pre-arthritic hip diseases (FAIS, AD).
Participants with FAIS or AD, aged 18 and older, completed the IPAQ and wore accelerometers for 7 days. We compared IPAQ-reported moderate-to-vigorous physical activity (MVPA) with accelerometer-measured sedentary behavior, light PA, and MVPA using Pearson correlations and Bland-Altman plots.
Fifty-four individuals with FAIS or AD participated. We did not find any significant correlations between IPAQ-MVPA and accelerometer-measured PA variables. Bland-Altman plots revealed a positive systematic bias between IPAQ-MVPA scores and accelerometer-measured MVPA.
The IPAQ-MVPA scores showed divergent validity compared to accelerometer data in individuals with FAIS and AD. Future studies should integrate both self-report and device-based measures to enhance accuracy.
国际体力活动问卷（IPAQ）被广泛用于评估体力活动（PA），但其与股骨髋臼撞击综合征（FAIS）和髋臼发育不良（AD）患者通过设备测量的PA数据相比的有效性仍未得到充分研究。我们评估了通过IPAQ自我报告的PA与患有关节炎前期髋关节疾病（FAIS、AD）患者的加速度计数据之间结构效度的收敛性和发散性方面。
年龄在18岁及以上的FAIS或AD患者完成IPAQ并佩戴加速度计7天。我们使用Pearson相关性和Bland-Altman图比较了IPAQ报告的中度至剧烈体力活动（MVPA）与加速度计测量的久坐行为、轻度PA和MVPA。
54名患有FAIS或AD的个体参与了研究。我们未发现IPAQ-MVPA与加速度计测量的PA变量之间存在任何显著相关性。Bland-Altman图显示IPAQ-MVPA分数与加速度计测量的MVPA之间存在正向系统偏差。
在患有FAIS和AD的个体中，IPAQ-MVPA分数与加速度计数据相比显示出发散效度。未来的研究应整合自我报告和基于设备的测量方法以提高准确性。
