Habitual physical activity in patients born with oesophageal atresia: a multicenter cross-sectional study and comparison to a healthy reference cohort matched for gender and age.

• Patients with oesophageal atresia have a similar amount of sports activity per week but engage significantly less in moderate to vigorous physical activities compared to peers. • Physical activity was  associated with weight-for-age and height-for-age, but largely independent of symptom load and other medical factors.
