Physical activity is linked to fewer psychosomatic problems in adolescents with ADHD symptoms

Insufficient physical activity among adolescents, combined with poorer well-being and mental health, are worrying societal problems. Adolescents with ADHD encounter daily challenges and are more prone to experiencing mental and physical health issues compared to their peers. The aim was to investigate associations between moderate-to-vigorous physical activity, sedentary time, screen-time, psychosomatic problems, and ADHD symptoms in adolescents. Data came from a cross-sectional study. Participants (N = 1139) were seventh-grade students who answered questionnaires on screen-time, psychosomatic problems, hyperactivity, and ADHD and were assigned an accelerometer, worn for seven consecutive days. Data were analyzed using linear regression. A negative association was found between moderate to vigorous physical activity and psychosomatic problems in the entire sample. Moderate-to-vigorous physical activity was more strongly associated with psychosomatic problems for adolescents with self-reported ADHD symptoms (B = −0.14 (−0.24, −0.04)) than adolescents without ADHD symptoms (B: -0.03 (−0.05, −0.01)). Moderate-to-vigorous physical activity, sedentary time, and screen-time were all significantly associated with psychosomatic problems among all participants. Moderate-to-vigorous physical activity showed a stronger association with psychosomatic problems among participants with ADHD. This indicates that this group may be particularly responsive to interventions attempting to promote mental health through physical activity. Till ‘Mental health and physical activity’ • Sedentary time and screen time were associated with more psychosomatic problems. • Physical activity was associated with lower psychosomatic problems. • Physical activity reduced psychosomatic problems especially in those with ADHD. • Physical activity interventions should target and fit those with ADHD.
