RESUMEN
In China, the aging of the population is becoming increasingly serious. Common diseases of the elderly, such as sarcopenia and metabolic syndrome, have gradually become key factors affecting their quality of life. Sarcopenia is a decline in skeletal muscle mass and function associated with aging. Metabolic diseases such as obesity, hypertension and diabetes play an important role in the development of sarcopenia. In recent years, the relationship between sarcopenia and metabolic syndrome has also become a research hotspot, but there is still a lack of strong evidence on whether they are a risk factor for each other. This paper summarizes the epidemiological data of the relationship between sarcopenia and metabolic syndrome in the last 5 years, and reviews the epidemiological background, research status and potential links in biological mechanism of sarcopenia and metabolic syndrome. There is a significant correlation between sarcopenia and metabolic syndrome that may share similar biological mechanisms. However, there are still some limitations in this study. In addition, the methods of early screening and diagnosis of sarcopenia should be continuously explored to achieve the purpose of simplicity, rapidity and efficiency. This review aims to raise the population's awareness of chronic syndromes sarcopenia and metabolic syndrome, and to provide theoretical support for further research on their relevance.
