The prevalence of global physical activity among young people: a systematic review for the Report Card Brazil 2018

Abstract

The aim of this study was to summarize data on the prevalence of global physical activity (PA) among children and adolescents in Brazil. This systematic review included an electronic search in 8 databases (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar) and a manual search in the references of retrieved studies. Observational studies that assessed global PA among Brazilian children and adolescents were included. A narrative approach toward results was adopted. An initial database search reached 3276 potentially relevant titles (2534 titles after duplicate analysis); 92 (62 different studies) met all inclusion criteria. Studies were carried out between 2001 and 2015; most studies were conducted in Southern and Northeastern Brazil. Three were nationwide surveys (4.8%), but no studies included children aged 0-5 years. Eighteen different instruments for PA measurement were used; only two studies used objectively-measured PA. The most used definition was ≥ 300 minutes/week of moderate-to-vigorous PA. The overall proportion of young people who were physically active ranged from 6.5% to 92.3%. Fourteen studies (22.6%) found a prevalence of ≥ 50%. Three nationwide surveys reported the prevalence of physically active students ranging from 29.0% to 66.0%. A wide variability of PA estimates were found. Important research gaps (e.g., studies with objectively-measured PA, children aged up to 6 years-old and in Northern Brazil) should be considered to develop new research studies in Brazil.

Escore contínuo de risco metabólico em escolares com diferentes níveis de aptidão cardiorrespiratória

“…Simultaneamente, exercícios aeróbicos, isométricos e resistidos são capazes de melhorar os níveis de pressão arterial e glicemia em indivíduos com hipertensão, diabetes e SM, desde que sejam atingidos os níveis mínimos semanais recomendados de atividade física de intensidade moderada a intensa 5 . Todavia, segundo 35 estudos encontrados em revisão sistemática realizada por Barbosa Filho e colaboradores 6 , mais de 50% das crianças e adolescentes brasileiros são inativos fisicamente.…”

Prevalence of global physical activity among young people: an updated systematic review for the Brazil’s Report Card

“…This study is an updated systematic review of Barbosa Filho et al, 4 which included information on studies published from January 2018 to December 2019. The previous search, selection criteria, and synthesis strategies were considered in the updated review.…”

“…To foster this initiative, PA indicators (e.g., meeting PA guidelines, active transportation, and others) have been monitored and described in a document called "Report Card," intended to serve as a useful tool for the advocacy of PA 2 among young people. In 2018, data from 49 countries were compiled, including Brazil 3,4 , where the global PA levels (prevalence rate of 31.1%) had a grade of D (grades ranged from A to E) based on data from 94 studies with Brazilian children and adolescents 3,4 . Global PA monitoring allows us to estimate the proportion of the population that "complies" with the PA guidelines.…”

“…However, this monitoring can be affected in different ways by the instrument used and data analysis, for example 5 . Hence, the present study aimed to update the systematic review 4 on the prevalence of global PA among Brazilian children and adolescents.…”

“…As recomendações para o grupo etário de 5 a 17 anos é de pelos menos 60 minutos diários de atividade física moderada a vigorosa (AFMV) (WHO, 2010). No entanto, os estudos têm revelado que mais de 80% dos adolescentes em todo o mundo, não tem acumulado o tempo de AFMV suficiente para obter os benefícios para saúde e esta tendência também tem sido evidenciada entre os jovens brasileiros (Barbosa et al, 2018;WHO, 2018). A falta de oportunidades para a prática de AF em locais seguros e acessíveis se constitui uma das barreiras, principalmente para jovens com baixo status socioeconômico.…”
