Abstract
Purpose: The purpose of this study is to analyze the associations between participation in physical education (PE) classes and days with ≥60 minutes of moderate- to vigorous-intensity physical activity (MVPA) using different reference categories for participation in PE.
Methods: We used self-reported data from 284,820 adolescents.
Results: When no participation in PE was the reference, participation on 1 (prevalence ratio [PR] = 1.15 [1.12-1.18]), 2 (PR = 1.24 [1.20-1.27]), 3 to 4 (PR = 1.32 [1.28-1.36]), and ≥5 days per week (PR = 1.8 [1.33-1.43]) increased frequency of days of ≥60 minutes of MVPA. Participating in PE on 2 (PR = 1.07 [1.02-1.09]), 3 to 4 (PR = 1.15 [1.12-1.18]), and ≥5 days per week (PR = 1.18 [1.15-1.22]) increased the days of ≥60 minutes of MVPA when participation in PE classes on 1 days per week was the reference. When participation in PE on 2 days per week was the reference, participation in PE classes on 3 to 4 (PR = 1.07 [1.04-1.09]) and ≥5 days per week (PR = 1.12 [1.09-1.15]) increased the days of ≥60 minutes of MVPA. Participating in PE classes on ≥5 days per week increased the days of ≥60 minutes of MVPA (PR = 1.05 [1.03-1.07]) when participation on 3 to 4 days per week was the reference.
Conclusions: For those with no participation in PE classes, the addition of any PE classes could positively impact the weekly frequency of days of ≥60 minutes of MVPA. Even in countries/territories with large coverage of participation in PE classes, promoting more PE classes could be useful to increase physical activity.
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.
