Changes in Leisure-Time Physical Activity and Active Commuting to School From Before to After the COVID-19 Pandemic Among Adolescents in Brazil: Repeated Cross-Sectional and Longitudinal Analyses.
Purpose: Compare leisure-time physical activity (LTPA) and active commuting to school among Brazilian adolescents between the periods before COVID-19 and after the reopening of schools.
Methods: This is a repeated cross-sectional study with a nested cohort targeting high school students from Southern Brazil. LTPA and active commuting to school were the self-reported outcomes. Zero-inflated Gamma and Logistic Mixed models were applied to compare, respectively, LTPA and active commuting between survey years.
Results: Cross-sectional analyses showed that the odds of engaging in any type of LTPA were similar between waves. However, active participants spent significantly more time in total LTPA (9.5 min/d), team sports (4.9 min/d), and fitness activities (7.7 min/d) in 2022 (n = 954; 52.0% female; 16.5 [1.2] y) than in 2019 (n = 824, 51.2% female; 16.4 [1.1] y). Prospective analyses of 286 adolescents (54.5% female) showed a reduction in the probabilities of engaging in total LTPA (-17%), team sports (-36%), and individual sports (-10%) from 2019 to 2022. No changes were found for active commuting.
Conclusions: Cross-sectional and prospective differences were found for leisure but not for commuting-related physical activity between pre- and postpandemic periods. Efforts to promote physical activity should remain a public health priority.
期刊介绍：
Pediatric Exercise Science is a journal committed to enriching the scientific knowledge of exercise during childhood and adolescence. To this end it publishes information that contributes to an understanding of (a) the unique aspects of the physiologic, physical, biochemical, and psychologic responses of children to exercise, (b) the role of exercise in the treatment of pediatric chronic diseases, (c) the importance of physical activity in the prevention of illness and preservation of wellness, and (d) the means by which participation in sports may be made safer and more enjoyable for children and youth. Consideration will be given for publication of work by various methodologies consistent with the scientific approach.
Besides original research, the journal includes review articles, abstracts from other journals, book reviews, and editorial comments. Pediatric Exercise Science encourages the expression of conflicting opinions regarding children and exercise by providing a forum for alternative viewpoints. At the same time it serves as a means of accumulating a base of research information that will allow application of experimental data to clinical practice. The scientific disciplines contributing to this body of knowledge are diverse. Therefore it is the purpose of this journal to provide a common focus for disseminating advances in the science of exercise during childhood. In doing so, the journal allows the opportunity for cross-fertilization of ideas between disciplines that will potentiate the growth of knowledge in this field. Pediatric Exercise Science seeks to stimulate new ideas regarding exercise in children and to increase the awareness of scientists, health care providers, and physical educators of the importance of exercise during childhood.
