Resumo O objetivo deste estudo foi descrever a prevalência de participação esportiva em crianças e adolescentes brasileiros por meio de uma revisão sistemática de literatura. A busca foi realizada nas seguintes bases de dados eletrônicas: MEDLINE, WEB OF SCIENCE, BIREME, SCIELO e SCOPUS de manuscritos publicados até o ano de 2020, por meio da combinação das palavras-chave: “crianças”, “adolescentes”, “prevalência” e “participação esportiva”, em português e inglês. Foram incluídos na revisão 26 artigos publicados no período de 2003 a 2020, com objetivo de estimar a prevalência de crianças e adolescentes brasileiros acerca da participação em esportes organizados. Quanto a região de realização do estudo, a maioria foi desenvolvido no sul (57.7%; n=15), seguido do sudeste (19.2%; n=05) e nordeste (15.4; n=04), além de 7.7% (n=02) em todas as regiões do país. Os dados mostraram prevalências de participação esportiva que variaram entre 15.0% a 73.2% (média de 44.8%) entre crianças e adolescentes, sendo superior no sexo masculino (63.1%). A partir dos resultados encontrados evidencia-se a necessidade do desenvolvimento de políticas públicas para favorecera aderência e manutenção de jovens para a prática esportiva, principalmente entre aqueles do sexo feminino.

Abstract The aim of this study is to describe the prevalence of sports participation in Brazilian children and adolescents through a systematic literature review. A search was carried out in the following electronic databases: MEDLINE, WEB OF SCIENCE, BIREME, SCIELO, and SCOPUS for manuscripts published until 2020, combining the keywords: “children”, “adolescents”, “prevalence”, and “sports participation”, in Portuguese and English. Twenty-six articles published between 2003 and 2020 were included in the review, with the aim of estimating the prevalence of participation in organized sports in Brazilian children and adolescents. Considering the regions where the studies were carried out, the majority were developed in the south (57.7%; n=15), followed by the southeast (19.2%; n=05), and northeast (15.4%; n=04), in addition to 7.7% (n=02) in all regions of the country. The data showed prevalence of sports participation ranging from 15.0% to 73.2% (mean of 44.8%) among children and adolescents, being higher in males (63.1%). From the results found, the need to develop public policies is evident, in order to favor adherence and maintenance of young people to sports practice, especially among those of the female sex.

Objective Analyze the influence of sarcopenia in bone health of elderly men. Subjects and methods This cross-sectional study evaluated 198 men aged over 60 years. Body composition was measured by dual energy X-ray absorptiometry. The BMD was measured at the femoral neck, total hip, lumbar spine and 33% radius. The diagnosis of abnormal BMD was defined for men who presented densitometric diagnosis of osteopenia or osteoporosis defined by T-score of femoral neck, total hip and lumbar spine. The pre-sarcopenia and sarcopenia were defined according to the European Working Group on Sarcopenia in Older People. Results The group diagnosed with normal BMD, compared to the group of abnormal BMD, have significantly higher body weight, body mass index, grip strength, lean mass, fat mass, and relative appendicular skeletal muscle mass (RASM). However, after multiple linear regression analysis, we found that only the RASM, lean mass, and handgrip strength in the dominant hand influenced the variability of the BMD after adjustment for age and weight. Regression analyzes showed a positive association between greater appendicular lean mass and a smaller number of elderly patients with abnormal BMD diagnostic. The regression analyzes showed that elderly men diagnosed with pre-sarcopenia and sarcopenia had more abnormal BMD than non-sarcopenic elderly men. Conclusion We concluded that pre-sarcopenia and sarcopenia were associated with abnormal BMD. The lean mass, compared to fat mass, has a greater positive influence on the BMD of elderly men. This result suggests the importance of the increase in lean mass for the bone health of elderly men. Arch Endocrinol Metab. 2015;59(1):59-65

OBJETIVOS: Comparar a ultrassonometria do calcâneo com a densitometria óssea na avaliação de fraturas vertebrais morfométricas em homens acima de 60 anos. SUJEITOS E MÉTODOS: Foram analisados 96 homens com mais de 60 anos por meio de densitometria óssea da coluna, fêmur e rádio, radiografia lateral da coluna torácica e lombar e ultrassonometria do calcâneo. RESULTADOS: Cinquenta e um por cento dos homens apresentaram osteoporose e fraturas vertebrais. Foi observada correlação entre índice de stiffness e T-score da ultrassonometria e as densidades minerais ósseas (DMO) de todos os sítios. Quanto à presença de fraturas, identificou-se correlação com a DMO do rádio ultradistal e 33%. Por meio da curva ROC, observou-se acurácia da DMO do rádio UD na detecção de fraturas vertebrais. CONCLUSÕES: Nosso estudo mostrou correlação entre a ultrassonometria e a densitometria no diagnóstico de osteoporose em homens acima dos 60 anos. Também se identificou correlação entre fratura vertebral morfométrica e a DMO do rádio.

OBJECTIVES: To compare calcaneal ultrasonometry and bone densitometry in the evaluation of morphometric vertebral fractures in men over 60 years of age. SUBJECTS AND METHODS: We studied 96 men over 60 years of age by means of bone densitometry of the spine, femur and radius, lateral radiograph of the thoracic and lumbar spine, and calcaneal ultrasonometry. RESULTS: Fifty-one percent of men had osteoporosis and vertebral fractures. Correlation was found between ultrasonometry stiffness index, T-score and bone mineral density of the spine, femur and radius (p < 0.01). Regarding the presence of fractures, there was a correlation only with BMD of the ultradistal radius (UD) and radius 33%. ROC curve showed accuracy only of UD radius BMD in detecting vertebral fractures. CONCLUSIONS: Our study showed a correlation between osteoporosis diagnosis by ultrasonometry and densitometry in men over 60 years. It also showed a correlation between morphometric vertebral fracture and bone mineral density of the forearm.
