Regular physical activity (PA) has been proven to help prevent non-communicable diseases and is beneficial for disease management in chronically ill populations. Physical inactivity and recreational screen-based media (SBM) use are related to poor health outcomes and common among youth. This study aimed to (1) investigate PA levels and recreational SBM use of adolescents with JIA over time and (2) compare these behaviours with those of their peers.
Data from JIA patients and their peers enrolled in the inception cohort study ICON at 11 German centers were analyzed. Individuals aged 13 and over were followed prospectively with questionnaires concerning PA level, recreational SBM use, and health-related quality of life (HRQoL) at a two-year interval. Group by time interactions were analyzed using linear mixed models.
Data of 214 patients (mean age at first documentation 14.4 ± 0.9 years, female 63%) and 141 peers could be considered. At first documentation, patients were less physically active compared to their peers (p < 0.001). In contrast to their peers, patients' PA levels increased over time (OR 3.69; 95% CI: 1.01-13.50, p = 0.048). Mean screen time did not differ significantly between patients and peers (first documentation: 3.5 h vs. 3.0 h, p = 0.556; follow-up: 3.6 h vs. 3.3 h, p = 0. 969). During the observation period, male patients reported higher PA levels than female patients, but also higher screen time levels. While low socioeconomic status (SES) (OR 14.40; 95%-CI: 2.84-73.15) and higher cJADAS-10 score (OR 1.31; 95%-CI: 1.03-1.66) increased the likelihood for high SBM use (≥ 4.5 h/d), higher PedsQL psychosocial health score (OR 0.93; 95%-CI: 0.88-0.99) was associated with a decreased likelihood.
Adolescents with JIA become more physically active over the disease course and achieve comparable levels of PA and recreational screen time to their peers. However, the vast majority appear to be insufficiently physically active. Future interventions to promote healthy lifestyles should include gender and SES as important determinants to reach most vulnerable groups.
有研究证实，有规律的身体活动（PA）有助于预防非传染性疾病，对慢性病患者的疾病管理也有益处。身体活动不足和娱乐性屏幕媒体（SBM）的使用与较差的健康结果有关，且在青少年中较为常见。本研究旨在：（1）随时间推移，调查青少年特发性关节炎（JIA）患者的 PA 水平和娱乐性 SBM 使用情况；（2）将这些行为与同龄人进行比较。
对来自德国 11 个中心 ICON 起始队列研究的 JIA 患者及其同龄人的数据进行分析。13 岁及以上的个体每两年通过问卷接受一次关于 PA 水平、娱乐性 SBM 使用和健康相关生活质量（HRQoL）的前瞻性随访。使用线性混合模型分析组与时间的交互作用。
共纳入 214 名患者（首次记录时的平均年龄为 14.4±0.9 岁，女性占 63%）和 141 名同龄人的数据。首次记录时，患者的 PA 水平明显低于同龄人（p<0.001）。与同龄人相比，患者的 PA 水平随时间推移而增加（比值比 3.69；95%置信区间：1.01-13.50，p=0.048）。患者和同龄人之间的平均屏幕时间无显著差异（首次记录：3.5 小时比 3.0 小时，p=0.556；随访：3.6 小时比 3.3 小时，p=0.969）。在观察期间，男性患者报告的 PA 水平高于女性患者，但报告的屏幕时间也较高。较低的社会经济地位（SES）（比值比 14.40；95%置信区间：2.84-73.15）和较高的 cJADAS-10 评分（比值比 1.31；95%置信区间：1.03-1.66）增加了高 SBM 使用（≥4.5 小时/天）的可能性，而较高的 PedsQL 心理社会健康评分（比值比 0.93；95%置信区间：0.88-0.99）则降低了这种可能性。
青少年特发性关节炎患者在疾病过程中变得更加活跃，PA 水平和娱乐性屏幕时间与同龄人相当。然而，绝大多数患者的身体活动量仍然不足。未来促进健康生活方式的干预措施应将性别和 SES 作为重要决定因素，以覆盖最脆弱的群体。
