Are There Differences in the Physical Activity Level and Functional Capacity among Children and Adolescents with and Without Asthma?

Objective: The aim of this study was to analyze the physical activity level, using two tools, and the functional capacity of children and adolescents with asthma and with different levels of disease control, and to compare them to those of individuals without asthma. Methods: Cross-sectional study with children and adolescents with (asthma group, AG) and without asthma (WAG), aged from 7 to 17 years. All participants performed the six-minute walk test (6MWT), the Glittre Activities of Daily Living test (Glittre-ADL), the International Physical Activity Questionnaire (IPAQ), and daily record of steps on a pedometer. Results: The study included 145 individuals with asthma and 173 individuals without asthma. The WAG walked a greater distance in the 6MWT and performed the Glittre-ADL in less time than the AG. Individuals with uncontrolled, partially controlled, and controlled asthma presented the same functional capacity. A difference was observed in the IPAQ classification, with 13.9% of participants from the WAG being sedentary, compared with 26.2% in the AG. The mean quantity of steps measured by the pedometer was higher in the WAG. Conclusion: There was a difference in the performance of individuals with and without asthma in the physical activity and functional capacity tests. The AG presented worse performance in the physical activity tests and, regardless of the level of asthma control, presented worse functional capacity. (C) 2020 Sociedade Brasileira de Pediatria.
