ABSTRACT
This study investigated the association among loneliness, number of friends, and participation in physical education classes, leisure-time physical activities, and active commuting. Data from 102,072 adolescents participating in the National School-based Health Survey aged 11-19 years were analyzed. Information about the study variables was self-reported through a questionnaire. Adolescents more active in physical education classes and leisure were less likely of having social isolation. Those more active in commuting were more likely of having social isolation. Interventions aimed at addressing social isolation in adolescence can prioritize school and leisure-time physical activities.

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.
RESUMO Objetivou-se identificar a evidência quanto às associações entre atividade física (AF) e saúde mental (SM) em adolescentes escolarizados brasileiros. Trata-se de um estudo de Revisão Sistemática. Os estudos foram selecionados em português e inglês e identificados por meio de uma busca sistemática em seis bases de dados eletrônicas: PubMed, Web of Science, SPORTDiscus/Ebsco, ScIELO, ERIC, e LILACS, que compreendeu publicações até o final de 2019. Os critérios de inclusão foram: estudos com um desenho de coorte, descritivo de caráter exploratório, transversal, ou qualitativos; realizados com crianças e adolescentes; estudos que analisaram a relação entre AF e SM; estudos que investigaram adolescentes que praticavam AF nas escolas; estudos realizados no Brasil e os que obtiveram a pontuação mínima estabelecida de 60% conforme os critérios da qualidade metodológica do instrumento STROBE. A Educação Física oferecida no currículo da educação básica tem um efeito protetor sobre a SM no ambiente escolar. Além disso, mais de 300 min/semana de AF foi associado positivamente com a SM. Algumas associações foram negativas entre a AF e a SM, tais como: tempo excessivo de TV; isolamento social; insatisfação com o peso corporal. A AF escolar está associada positivamente à SM por promover bem-estar físico e psicológico, impactando na redução dos índices de problema de insônia, atenuando a solidão e melhorando a aparência física.
