Abstract: Ｏｂｊｅｃｔｉｖｅ：To assess prevalence of sarcopenia and sarcopenia obesity in maintenance hemodialysis(MHD) patients,and analyze the risk factors.
Ｍｅｔｈｏｄｏｌｏｇｙ：One hundred and twenty patients who received MHD treatment in the Second Hospital of Shanxi Medical University from October 2019 to March 2020 were enrolled.Asian sarcopenia diagnostic criteria were used to screen patients.According to the percentage of body fat (male≥25％,female≥35％),patients with sarcopenia were divided into sarcopenia obesity group and sarcopenia nonobesity group,the nutrition and exercis indicators were compared.
Ｒｅｓｕｌｔｓ：In MHD patients,the prevalence of sarcopenia was 3080％,positiuely related with age,the prevalence of sarcopenia obesity was 1500％.The age of patients with sarcopenia was significantly higher than that of patients without sarcopenia.Their handgrip strength,dry weight,diastolic blood pressure,dehydration rate,serum albumin,β2 microglobulin,predialysis serum creatinine,blood iron,the total ironbinding capacity,physical activity,average daily protein intake,and average daily energy intake were significantly lower than those of patients without sarcopenia (P<005).Logistic regression showed that low physical activity,average daily protein intake <09 g／(kg·d),weak handgrip strength,and light dry weight were risk factors for sarcopenia in maintenance hemodialysis patients.
Ｃｏｎｃｌｕｓｉｏｎ：
Low physical activity,average daily protein intake,weak handgrip strength,and light dry weight were risk factors for sarcopenia in MHD patients.

Key words: maintenance hemodialysis, sarcopenia, sarcopenia obesity, body composition, risk factors
