Objective To assess the physical activity (PA) levels in preschool children with Kawasaki disease (KD) during the early stages of the illness,in order to provide reference for making individualized exercise prescriptions. Methods Children hospitalized at the Children's Hospital of Capital Institute of Pediatrics between December 2023 and March 2024 were selected as the KD group. Healthy children matched by gender and age in a 1∶3 ratio served as the control group. The Preschooler Physical Activity Questionnaire (P-PAQ) was used to evaluate the PA levels of the KD group one month after the onset of the disease, focusing on their physical activity over the past week. The clinical data of KD patients were collected through the electronic medical system, including gender, age, height, weight, treatment, laboratory indicators (blood routine, C-reactive protein) and ultrasound results of coronary arteries. Results A total of 112 children were included in the study, comprising 28 KD patients and 84 healthy controls. One month after the onset of KD, the total out-of-school activity time was 99.36 (56.79, 130.18) minutes per day, the outdoor activity time was 12.86 (10.71, 14.29) minutes per day, and the moderate-to-vigorous physical activity (MVPA) time was 26.25 (7.50, 53.32) minutes per day. Compared to the healthy control group, the KD group showed significantly reduced total out-of-school activity time, outdoor activity time, and MVPA time (Z=5.491, 5.072, 3.726, P<0.01). All KD patients were followed up one month after the onset of the disease, and no coronary artery complications or adverse cardiovascular events were observed. Conclusions Preschool children with KD without coronary artery complications exhibit low levels of physical activity during the early stage of the disease. Actively exploring individualized exercise prescriptions based on evidence-based medicine during the recovery phase holds significant clinical importance.
