ABSTRACT CONTEXT: The relationship with body image, which is the way the body presents itself to each subject, can be aggravated in children and adolescents diagnosed with an human immunodeficiency virus (HIV) infection, since these patients use antiretroviral therapy and may suffer from the adverse effects of the treatment due to continuous use of medication. OBJECTIVE: To estimate the prevalence of body image dissatisfaction, to describe the assessment methods, and to identify associated factors in children and adolescents diagnosed with HIV. DESIGN AND SETTING: This is a systematic review. Department of Physical Education, Florianópolis - Brazil METHODS: We followed the procedures of the Preferred Reporting Items for Systematic Reviews (PRISMA) and the Cochrane recommendations in the selection of articles through a search performed in eight databases. RESULTS: Prevalence of body image dissatisfaction due to thinness was between 36.7–52.0% in males and 28.1–36.4% in females, and body image dissatisfaction due to overweight was between 8.0–31.2% in males and 21.9–50.0% in females. Factors associated with body image dissatisfaction were as follows: female sex, older age, low levels of physical activity, low self-esteem, higher body fat, higher body weight, greater arm muscle area, triceps skinfold thickness, and higher body mass index. CONCLUSION: Children and adolescents of both sexes diagnosed with HIV infection are dissatisfied by thinness and overweight of their body image.

ABSTRACT BACKGROUND: During childhood and adolescence, there are significant increases in bone mineral content (BMC) and bone mineral density (BMD). OBJECTIVE: To investigate physical growth parameters associated with BMD and BMC among children and adolescents diagnosed with human immunodeficiency virus (HIV). DESIGN AND SETTING: Cross-sectional study conducted in Florianópolis, Brazil, among 63 children and adolescents (aged 8-15 years) diagnosed with HIV. METHOD: BMD, BMC and fat percentage z score were evaluated using dual X-ray absorptiometry. Age/height z score and body mass index (BMI)/age z score were obtained in accordance with international recommendations, and bone age was obtained through hand-wrist radiography. Sex, family income, information on HIV infection (T CD4+ lymphocyte count, viral load and type of antiretroviral therapy, moderate-vigorous physical activity and sedentary behavior) were used as adjustment variables in the analyses. Simple and multiple linear regression analyses were performed, with a significance level of P ≤ 0.05. RESULTS: Subtotal BMD (without the head region) was directly associated with bone age, BMI/age z score and fat percentage z score, even after adjusting for covariates. Subtotal BMC/height was directly associated with bone age, height/age z score, BMI/age z score and fat percentage z score, even after adjusting for covariates. CONCLUSION: Subtotal BMD and subtotal BMC/height were directly associated with physical growth indicators among children and adolescents diagnosed with HIV.

RESUMO O estudo teve como objetivo identificar e sumarizar evidências referentes à avaliação dos níveis de força muscular (FM) em crianças e adolescentes escolares (≤ 19 anos) no Brasil, com o intuito de atualizar as evidências publicadas anteriormente pelo projeto Report Card Brazil. A busca sistemática das informações foi conduzida em sete bases de dados, restrita aos estudos publicados durante o período de Janeiro de 2018 a Dezembro de 2019. Treze estudos foram incluídos, o que reuniu informações de 10.135 crianças e adolescentes de sete estados brasileiros. Diferentes testes/protocolos para avaliar a FM foram identificados, contudo, a força de preensão manual foi o teste mais empregado pelos estudos (53,8%). A prevalência de crianças e adolescentes que apresentavam níveis de FM considerados saudáveis foi de 29,8% considerando a totalidade de informações, e 27,6% para os meninos e 31,8% para as meninas. Considerando a totalidade de dados revisados pelo projeto Report Card Brazil (informações analisadas neste estudo em adição aos anteriormente publicados), o corpo de informações referente a avaliação dos níveis de FM em crianças e adolescentes no Brasil foram advindas de pesquisas conduzidas durante o período de 2010 a 2019, o que reuniu amostra de 15.208 crianças e adolescentes (sete a 19 anos). De acordo com estas informações, a prevalência de crianças e adolescentes que apresentavam níveis de FM considerados saudáveis nesse período foi de 57,8%, sendo que no sexo masculino foi de 61,1% e no sexo feminino de 58,8%.

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.

resumo O objetivo do estudo foi realizar uma atualização das evidências brasileiras sobre a prevalência de crianças e adolescentes que atenderam aos critérios de saúde para aptidão aeróbia. Essa revisão sistemática integra o Projeto Report Card Brasil e a busca foi restrita aos estudos publicados durante o período de Janeiro de 2018 a Dezembro de 2019 em nove bases de dados eletrônicas. Estudos com diferentes delineamentos, os quais permitiram extrair informações acerca da prevalência de crianças e adolescentes que atenderam aos critérios de saúde para a aptidão aeróbia (idade até 19 anos ou com média de idade até 19 anos) foram incluídos. Estudos publicados a partir de 2020 não foram incluídos por conta do possível efeito da pandemia nesse indicador e por não haver uma certeza de quando finalizará a pandemia. Do total de 694 estudos inicialmente identificados, 13 estudos com informações de 14.673 crianças e adolescentes foram incluídos após a leitura de títulos, resumo, textos completos e referências. A prevalência de crianças e adolescentes que atenderam aos critérios de saúde para aptidão aeróbia foi de 26.9% (29,7% para as meninas; 44,6% para os meninos). Nessa busca, oito pontos de corte distintos para determinar níveis adequados de aptidão aeróbia foram utilizados, bem como cinco testes foram empregados para se determinar a aptidão aeróbia. Analisando-se os dados da presente revisão com a revisão sistemática anterior desse projeto, um terço das crianças e adolescentes do Brasil atendem aos critérios de saúde para aptidão aeróbia.

abstract The aim of the study was to update Brazilian evidence on the prevalence of children and adolescents who met health criteria for aerobic fitness. This systematic review is part of the Report Card Brazil Project and the search was restricted to studies published during the period from January 2018 to December 2019 in nine electronic databases. Studies with different designs, which allowed extracting information about the prevalence of children and adolescents who met health criteria for aerobic fitness (age up to 19 years or average age up to 19 years) were included. Studies published from 2020 were not included due to the possible effect of the pandemic on this indicator and because there is no certainty as to when the pandemic will end. Of the 694 studies initially identified, 13 studies with information of 14,673 children and adolescents were included after reading titles, abstracts, full texts and references. The prevalence of children and adolescents who met health criteria for aerobic fitness was 26.9% (29.7% for girls; 44.6% for boys). In this search, eight different cutoff points were used to determine adequate aerobic fitness levels and five tests were used to determine aerobic fitness. Analyzing data from the present review with the previous systematic review of this project, one third of children and adolescents in Brazil meet health criteria for aerobic fitness.

RESUMO O objetivo do presente estudo foi comparar o índice de massa corporal [IMC], dobra cutânea do tríceps (DCTR), subescapular (DCSE) e gordura corporal (%GC) em atletas de ginástica rítmica (GR), satisfeitas e insatisfeitas com a imagem corporal (IC), Tratou-se de um estudo transversal, com 38 atletas praticantes de GR do Oeste Paranaense. A IC foi avaliada com o Body Shape Questionnaire, a massa corporal e a estatura foram aferidas e o IMC calculado. As DCTR e DCSE foram utilizadas para o cálculo do %GC (equação de Slaughter). O nível econômico foi verificado com o Critério de Classificação Econômica Brasil e a maturação sexual foi autorreferida com pranchas de Tanner. Foi empregado Teste T independente, Qui-quadrado e análise de covariância (ANCOVA) controlando a interferência do nível econômico e do estágio maturacional, com p<0,05. Ginastas insatisfeitas com a IC apresentaram maiores valores de IMC (média: 19,01 Kg/m2; desvio-padrão [DP]: 0,65 Kg/m2), DCTR (média: 9,26 mm; DP: 0,65 mm), DCSE (média: 7,33 mm; DP: 0,55 mm) e %GC (média: 20,75; DP: 0,96), quando comparadas às ginastas satisfeitas com a IC, mesmo após o controle do nível econômico e do estágio maturacional. Atletas de GR insatisfeitas com a IC apresentaram maiores valores para os indicadores antropométricos.

ABSTRACT This study aimed to compare body mass index [BMI], triceps skinfold (DCTR), subscapular skinfold (DCSE) and body fat (%BF) in rhythmic gymnastics (GR) athletes, satisfied and dissatisfied with body image (CI). Through a cross-sectional study with 38 athletes practicing GR from Oeste Paranaense. The CI was assessed with the Body Shape Questionnaire, body mass and height were measured, and the BMI was calculated. The DCTR and DCSE were used to calculate the %GC (Slaughter equation). The economic level was verified with the Brazil Economic Classification Criterion, and sexual maturation was self-reported with Tanner boards. Independent T-test and Chi-square and covariance analysis (ANCOVA) were employed to control the interference of economic level and maturational stage, with p <0.05. Gymnasts dissatisfied with HF presented higher BMI values (mean: 19.01 Kg/m2; standard deviation [SD]: 0.65 Kg/m2), DCTR (mean: 9.26 mm; SD: 0, 65 mm), DCSE (mean: 7.33 mm; SD: 0.55 mm) and %BF (average: 20.75; SD: 0.96) when compared to gymnasts satisfied with HF, even after control economic level and maturational stage. GR athletes dissatisfied with HF presented higher values for anthropometric indicators.
