Juvenile Idiopathic Arthritis (JIA) has been associated with decreased physical activity (PA). However, accurate, objective measurements of PA related to potential factors limiting PA in children with JIA have been lacking. Joint pain is a primary symptom of JIA and pain has been shown to be a significant predictor of impaired physical and psychosocial function, affecting the quality of life in these patients. Therefore, it could be anticipated that pain would explain the decreased PA in JIA. The use of pain-coping strategies and pain-specific health beliefs in children with JIA has previously been found to be associated with both clinical and experimental pain reports. Beliefs about a stressor such as pain are thought to influence an individual’s coping responses. We have previously reported that pain-related beliefs were significantly associated with pain in children with JIA even after controlling for disease-related variables and pain coping.
The aim was to relate accelerometer-assessed PA (PA-Acc) to disease activity, pain intensity, the use of pain coping strategies, pain-related health beliefs and health-related quality of life (HRQoL) measures in children with JIA.
PA was assessed using the hip-worn GT1M Actigraph accelerometer during wakening hours for one week, providing at least 3 separate days of each 8 hours of valid recording accelerometry in JIA patients using 10 sec. count-time periods (epochs). Demographic, disease and pain measurements, pain coping strategies assessed with the Pain Coping Questionnaire (PCQ), pain-specific beliefs assessed with the Survey of Pain Attitudes for Children (SOPA-C), and HRQoL assessed with the Pediatric Quality of Life Inventory (PedsQL), arthritis module, were simultaneously obtained.
Accelerometer data of 61 JIA patients (60.7%) were available for analysis. Accelerometer values of mean counts per minute (c/min), minutes with moderate and high PA (>1000 c/min) and high PA (>2500 c/min) were significantly lower in patients compared to normative values. Disease activity, expressed as JADAS-27, was negatively correlated to accelerometer counts. However, PA-Acc was neither correlated to pain intensity, pain coping strategies, nor to HRQoL. Accelerometer counts were significantly correlated to the pain-specific belief that one is in control of pain (‘Control’), but not to other pain-specific beliefs. In a hierarchical regression analysis ‘Control’ did not explain a significant unique part of the variance when controlling for JADAS-27, whereas JADAS-27 significantly explained 27% of the variance in moderate and high intensity PA when controlling for the health belief ‘Control’.
Accelerometer-assessed PA-levels of JIA-children were significantly lower than those of normative controls and were negatively correlated to JADAS-27. Levels of PA-Acc were not correlated to pain intensity, pain coping strategies, or HRQoL , but significantly correlated to the pain-specific belief that one is in control of pain (‘Control’).
