The purpose was to compare data obtained from a modified, long, self-administered version of the International Physical Activity Questionnaire (IPAQ-A) with objective data obtained in parallel from Actigraph accelerometers, and VO(2)max in adolescents. The study comprised a total of 2018 adolescents (46% male) from ten European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. Physical activity was assessed over seven consecutive days by accelerometry and expressed as min/day of moderate, vigorous, and moderate to vigorous (MVPA) physical activity (PA). PA was also assessed with the IPAQ-A. VO(2)max was estimated from a 20-m shuttle run test. Poor to fair correlations between the two methodologies were found for the whole study sample and when stratified by age and gender (r(s) = 0.08-0.26, p < 0.01). On average, the self-reported time spent in moderate PA was higher compared to the time measured with the accelerometer, while the differences between both instruments were less clear for vigorous intensity. Adolescents reporting high levels of PA (3rd tertile IPAQ-A) also showed higher levels of PA (accelerometers) in all the study variables (moderate, vigorous and MVPA), compared to adolescents reporting low PA (1st tertile IPAQ-A) (all p < 0.001). Both methods were moderately correlated with estimated VO(2)max. Within the HELENA-study, the IPAQ-A showed the modest comparability with the accelerometer data for assessing PA in each intensity level and was the highest for vigorous intensity. Both instruments are able to detect the adolescents with the highest cardio respiratory fitness, which are the most active adolescents.
本研究旨在比较经过改良的、长版本的国际体力活动问卷（IPAQ-A）的自我报告数据与并行获得的来自 Actigraph 加速度计和青少年最大摄氧量（VO2max）的客观数据。研究共纳入了来自欧洲十个城市的 2018 名青少年（46%为男性），他们参加了 HELENA（欧洲青少年营养与生活方式研究）。使用加速度计在连续七天内评估体力活动，并表示为每天中度、剧烈和中高强度体力活动（MVPA）的分钟数。也使用 IPAQ-A 评估体力活动。通过 20 米穿梭跑测试估计 VO2max。在整个研究样本以及按年龄和性别分层时，两种方法之间的相关性均较差（r(s) = 0.08-0.26，p < 0.01）。平均而言，与加速度计测量的时间相比，自我报告的中度体力活动时间较高，而对于剧烈强度，两种仪器之间的差异不太明显。报告高体力活动水平（IPAQ-A 的第三 tertile）的青少年在所有研究变量（中度、剧烈和 MVPA）中的体力活动（加速度计）水平也较高，而报告低体力活动水平（IPAQ-A 的第一 tertile）的青少年则较低（所有 p < 0.001）。两种方法与估计的 VO2max 均呈中度相关。在 HELENA 研究中，IPAQ-A 在评估各强度水平的体力活动方面与加速度计数据具有适度的可比性，在评估剧烈强度方面最高。两种仪器都能够检测到心肺功能最高的青少年，即最活跃的青少年。
