Introdução: A constante busca pela saúde e corpo perfeito, trouxe ao aplicativo Instagram um número considerável de usuários que utilizam o corpo como ferramenta discursiva e de convencimento, fazendo destes usuários guias de opinião diante dos demais. Objetivos: Sendo assim, buscou-se definir o perfil das publicações sobre nutrição esportiva no Instagram. Metodologia: A amostra compreendeu 58 perfis dedicados ao tema nutrição esportiva, identificados após a pesquisa dos verbetes “Nutrição Esportiva” e “Nutrição Fitness”, na área de busca do próprio aplicativo. Foi identificada a autoria e audiência dos perfis a partir dos dados apresentados em cada perfil avaliado, assim como, a quantificação dos seguidores e relacionou-se a audiência desses com as categorias analíticas de autoria. Resultados: Há cerca de 170 mil publicações sobre nutrição esportiva no Instagram. A maior parte foi publicada por perfis sem informações a cerca da inserção profissional dos autores (Loja de suplementos – 53%, sem definição - 17%). Os nutricionistas formados e os especializados em nutrição esportiva foram uns dos que menos possuíam perfis no aplicativo (15%), no entanto, foram os que apresentaram maior abrangência de público. Conclusão: Faz-se necessário o envolvimento dos profissionais nutricionistas na veiculação desses conteúdos nas redes sociais.
Key summary points
Aim
To identify the influence of sarcopenia and cachexia in prognostic markers in COVID-19 inpatients.
Findings
Sarcopenia is presented as a risk factor for mortality in COVID-19 inpatients.
Message
The accurate evaluation of nutritional abnormalities in hospitalized patients diagnosed with COVID-19 may help to reduce the risk for adverse outcomes.
Purpose:SARS-CoV-2 infection can lead to various manifestations beyond an inflammatory response, such as anorexia, hyposmia, and other symptoms that may increase the risk of nutritional disorders. Sarcopenia and cachexia (nutritional disorders) are conditions that appear to influence COVID-19 evolution. Thus, this study aimed to evaluate sarcopenia and cachexia in hospitalized patients with COVID-19, verifying their clinical impacts and relationship with prognostic markers.
Methods: This is a case-control study involving inpatients with and without a COVID-19 diagnosis. The occurrence of sarcopenia was evaluated according to European Working Group on Sarcopenia 2 criteria, and cachexia was also evaluated. Inflammatory markers and the 4C Mortality Score were evaluated.
Results: The groups were similar regarding age (p = 0.656), sex (p = 0.777), presence of comorbidities (type 2 diabetes p = 0.659; systemic arterial hypertension p = 0.427), and Body Mass Index (p = 0.657). The frequency of sarcopenia and cachexia in patients with COVID-19 was 21.9% and 28.1%, respectively. Sarcopenic patients with COVID-19 had a higher risk of death (4C Mortality Score) (p = 0.038). The occurrence of sarcopenia or cachexia within the COVID-19 group was not associated with inflammatory biomarkers or a higher number of COVID-19 symptoms (p > 0.05).
Conclusion: The presence of sarcopenia among COVID-19 patients increased the risk of mortality.
