目的：幼年特发性关节炎 (JIA) 可能会导致功能障碍、体力活动 (PA) 参与减少，并随着时间的推移导致身体不适。本研究的目的是使用加速度测量法客观监测 10-16 岁幼年特发性关节炎儿童的日常自由生活 PA 的疾病活动度和身体变量，并将数据与健康年龄和性别匹配对照的数据进行比较。方法：对患者进行疾病活动度、功能能力、身体能力和疼痛的评估。使用 GT1M ActiGraph 评估加速度计监测。使用来自丹麦学童 PA 的两项主要研究的规范数据进行比较。结果：61 名 JIA 患者和 2055 名健康对照者获得了加速度测量数据。在 JIA 患者中，57% 的最大体能（健康水平）低于平均水平。 JIA 患者的疾病活动度和疼痛程度较低，身体机能良好。 JIA 患者的加速计计数低于对照组。加速度计测量值与疾病活动度、红细胞沉降率 (ESR) 以及肿胀和/或活动范围 (ROM) 受限的关节数量呈负相关。 PA 与疼痛评分、功能能力和活动过度之间没有发现相关性。踝关节或髋关节受累的患者表现出明显较低的 PA 水平。结论：尽管疾病控制良好，但与年龄和性别匹配的健康同龄人相比，幼年特发性关节炎儿童的体力活动较少，体能和健康水平较低。髋部或踝部受累与 PA 降低有关。
Objectives: Juvenile idiopathic arthritis (JIA) may cause functional impairment, reduced participation in physical activity (PA) and, over time, physical deconditioning. The aim of this study was to objectively monitor daily free-living PA in 10-16-year-old children with JIA using accelerometry with regard to disease activity and physical variables and to compare the data with those from healthy age- and gender-matched controls.Method: Patients underwent an evaluation of disease activity, functional ability, physical capacity, and pain. Accelerometer monitoring was assessed using the GT1M ActiGraph. Normative data from two major studies on PA in Danish schoolchildren were used for comparison.Results: Data of accelerometry were available for 61 JIA patients and 2055 healthy controls. Of the JIA patients, 57% showed below-average values of maximal physical capacity (fitness level). JIA patients showed low disease activity and pain and were physically well functioning. Accelerometer counts were lower in JIA patients than in controls. Accelerometer measurements were negatively correlated with disease activity, erythrocyte sedimentation rate (ESR), and number of joints with swelling and/or limited range of motion (ROM). No correlation was found between PA and pain scores, functional ability, and hypermobility. Patients with involvement of ankles or hips demonstrated significantly lower levels of PA.Conclusions: Children with JIA are less physically active and have lower physical capacity and fitness than their age- and gender-matched healthy peers despite good disease control. The involvement of hips or ankles is associated with lower PA.
