The National Health and Nutrition Examination Survey (NHANES) in the United States is a research program designed to assess the health and nutritional status of adults and children in the country. Due to its adoption of a complex sampling design, it is imperative to correctly apply the weights provided by NHANES to ensure the accuracy and external validity of research results. This article first introduces the relevant concepts of the NHANES database and its weights, followed by a practical demonstration of weight selection, calculation, and implementation in the R programming language. It further discusses the significance of using weights in NHANES data and systematically showcases how to perform weighted analysis based on R, providing a valuable reference for relevant researchers.
Sarcopenia, a skeletal muscle degenerative condition, is inextricably linked to the physiological processes of aging. Sarcopenia is characterized by a reduction in muscle mass, a decline in muscle strength, and/or deterioration of physical function. Comprehensive interventions are essential for the management of sarcopenia. This patient version of guideline has been developed by adapting the " Comprehensive intervention for sarcopenia among older adults: an evidence-based clinical practice guideline." This patient version of guideline is designed to enhance health education and promote the widespread adoption of comprehensive intervention strategies for sarcopenia.
Sarcopenia, a skeletal muscle degenerative condition, is inextricably linked to the physiological processes of aging. Sarcopenia is characterized by a reduction in muscle mass, a decline in muscle strength, and/or deterioration of physical function. Comprehensive interventions are essential for the management of sarcopenia. The team from the National Clinical Research Center for Geriatrics has authored the "Comprehensive intervention for sarcopenia among older adults: an evidence-based clinical practice guideline" which discuss the specific contents of exercise, nutrition, and drug interventions for sarcopenia. This article provides a comprehensive interpretation of the guideline to facilitate their dissemination, promotion, and application.
With the continuous aging of the population in China, the aging of skeletal muscle in the elderly has seriously affected national health and poses a severe challenge to the public health system. Early detection of skeletal muscle aging, and early warning, prevention, and treatment are of great significance for achieving healthy aging. In order to select a series of clinically operable biomarkers for skeletal muscle aging, and to further standardize the early identification and precise diagnosis of skeletal muscle aging, a multidisciplinary team of experts has registered and written this protocol to provide a detailed introduction to the planning process for the development of the consensus.
