Report Card Brazil: systematic review of muscle strength assessment in children and adolescents in Brazil

Abstract

The present study aimed to identify and summarize evidence regarding muscle strength (MS) levels in school children and adolescents (≤ 19 years) in Brazil in order to update previously published evidence from the Report Card Brazil project. The systematic search for information was conducted in seven databases, restricted to studies published during the period from January 2018 to December 2019. Thirteen studies were included, which gathered information from 10,135 children and adolescents from seven Brazilian states. Different tests/protocols for assessing MS were identified, however, handgrip strength was the test most adopted in studies (53.8%). The prevalence of children and adolescents with MS levels considered healthy was 29.8%, considering the totality of information, and 27.6% for males and 31.8% for females. Considering full data reviewed by the Report Card Brazil project (data analyzed in this study in addition to those previously published), information regarding the assessment of MS levels in children and adolescents in Brazil came from studies conducted during the period from 2010 to 2019, which included a sample of 15,208 children and adolescents (aged 7-19 years). According to this information, the prevalence of children and adolescents with MS levels considered healthy in this period was 57.8%, 61.1% for males and 58.8% for females.

Adapted Physical Activity Policies for Children and Adolescents in Brazil: Extension of the Para Report Card Brazil

“…To obtain information on the physical activity programs/actions for children and adolescents with disabilities in Brazil, the following strategies were considered: (a) to review previous reports of the Report Card Brazil project published on the Active Healthy Kids Global Alliance website (https://www.activehealthykids. org/), (b) to review scientific articles on the Report Card Brazil project that were published in the Journal of Physical Activity and Health (Nardo et al, 2016;, and (c) review scientific articles on the Report Card Brazil project published in the Brazilian Journal of Kinanthropometry and Human Performance (original title in Portuguese: Revista Brasileira de Cineantropometria e Desempenho Humano; Lima et al, 2021;Silva & Tremblay, 2018).…”

Results from Brazil’s 2022 Report Card on Physical Activity for Children and Adolescents

“…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 ].…”
