ActiMON – Activity monitoring in adolescents and young adults with inflammatory rheumatic musculoskeletal diseases

Based on data from 126 patients with JIA (average age 15 years, 67% female), 24% achieved the minimum level of 60 minutes of moderate to vigorous physical activity per day recommended by the WHO. Among control subjects of the same gender and age from the general population, 8% achieved the recommended level of physical activity.

Relative to the total carrying time, patients spent significantly more time sitting than their peers in the general population (86% vs. 78%). On average, there were no differences in sitting behavior between weekdays and weekends in either the patient or control group.

Patients who spent less time sitting and/or fulfilled the exercise recommendations reported stronger family support in engaging in physical activities. The temporal composition of exercise behavior was also associated with health-related quality of life and enjoyment of exercise.
