School physical activity and mental health in school-aged Brazilian adolescents: a systematic review

Abstract

The aim of this study was to identify evidence regarding associations between School Physical Activity (PA) and Mental Health (MH) in Brazilian school-aged adolescents. This is a systematic review study. Studies were selected in Portuguese and English and identified by a systematic search in six electronic databases: PubMed, Web of Science, SPORTDiscus / Ebsco, ScIELO, ERIC, and LILACS, which comprised publications until 2019. Inclusion criteria were: studies with cohort, descriptive, cross-sectional or qualitative design; performed with children and adolescents; studies that analyzed the relationship between PA and MH; studies that investigated adolescents who practiced PA in schools; studies carried out in Brazil; and studies that reached minimum of 60% of methodological quality criteria according to STROBE. Physical education, as curricular activity in basic education, has protective effect on MH in the school setting. In addition, more than 300 min/week of PA was positively associated with MH; while associations between PA and excessive TV time; social isolation; and body weight dissatisfaction were negatively associated. School PA is positively associated with MH as it promotes physical and psychological well-being, impacting on the reduction of insomnia rates, attenuating loneliness and improving physical appearance.

“…The protocol for this research was published on the Open Science Framework (OSF) platform ( , accessed on 1 March 2022). To gather the best evidence available in Brazil on each indicator, the following strategies were adopted: Fourteen systematic reviews were conducted [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ], covering the following indicators: (1) Overall Physical Activity; (2) Organized Sport and Physical Activity; (3) Active Play; (4) Active Transportation; (5) Sedentary Behaviors; (6) Sleep; (7) Family and Peers; (8) Community and Environment; (9) Physical Fitness; (10) Obesity; (11) Poor Mental Health. In all systematic reviews, only studies with a sample of Brazilian children and adolescents published until December 2019—that is, before the COVID-19 pandemic—were considered eligible.…”

“…The target age for the samples investigated in the systematic reviews of this current report was adolescent children aged 5 to 19 years. All details about the samples can be consulted in previously published articles [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]; For the School indicator, an original study [ 26 ] was conducted with public data from the National Institute for Educational Studies and Research Anísio Teixeira (INEP); For the indicator related to Governmental Strategies and Investments, analyses were based on official information from the Brazilian Federal Government, in which official websites of the different Ministries in Brazil, national surveys of the federal government, and technical reports on the subject were researched. One paper about this indicator has been published [ 27 ].…”
