Previous research in children and adolescents with congenital heart defects presents contradictory findings concerning their physical activity (PA) level, due to methodological limitations in the PA assessment. The aim of the present cross-sectional study was to compare PA in children and adolescents treated for valvular aortic stenosis with healthy controls using an improved accelerometer method. Seven-day accelerometer data were collected from the hip in a national Swedish sample of 46 patients 6-18 years old treated for valvular aortic stenosis and 44 healthy controls matched for age, gender, geography, and measurement period. Sports participation was self-reported. Accelerometer data were processed with the new improved Frequency Extended Method and with the traditional ActiGraph method for comparison. A high-resolution PA intensity spectrum was investigated as well as traditional crude PA intensity categories. Children treated for aortic stenosis had a pattern of less PA in the highest intensity spectra and had more sedentary time, while the adolescent patients tended to be less physically active in higher intensities overall and with less sedentary time, compared to the controls. These patterns were evident using the Frequency Extended Method with the detailed PA intensity spectrum, but not to the same degree using the ActiGraph method and traditional crude PA intensity categories. Patients reported less sports participation than their controls in both age-groups. Specific differences in PA patterns were revealed using the Frequency Extended Method with the high-resolution PA intensity spectrum in Swedish children and adolescents treated for valvular aortic stenosis.
先前针对患有先天性心脏缺陷的儿童和青少年的研究在其身体活动 (PA) 水平方面得出了相互矛盾的结论，这是由于 PA 评估方法存在局限性。本横断面研究的目的是使用改进的加速度计方法比较接受主动脉瓣狭窄治疗的儿童和青少年与健康对照组的 PA。从瑞典全国样本中收集了 46 名 6-18 岁接受主动脉瓣狭窄治疗的患者和 44 名年龄、性别、地理位置和测量期间相匹配的健康对照组的 7 天髋部加速度计数据。运动参与情况是自我报告的。使用新的改进频率扩展方法和传统的 ActiGraph 方法处理加速度计数据进行比较。研究了高分辨率 PA 强度谱以及传统的粗糙 PA 强度类别。与对照组相比，接受主动脉瓣狭窄治疗的儿童在最高强度谱中的 PA 较少，且久坐时间更多，而青少年患者在整体更高强度和更少久坐时间方面的体力活动往往较少。这些模式使用带有详细 PA 强度谱的频率扩展方法很明显，但使用 ActiGraph 方法和传统的粗糙 PA 强度类别则不那么明显。两个年龄组的患者报告的运动参与度均低于对照组。使用带有高分辨率 PA 强度谱的频率扩展方法在瑞典接受主动脉瓣狭窄治疗的儿童和青少年中揭示了 PA 模式的具体差异。
