Abstract:
Objective To obtain the prevalence of sarcopenia in middle-aged and elderly people in Urumqi based on the 2020 updated based on the 2020 updated Consensus Report 2019 of Asian Working Group for Sarcopenia （AWGS2019）， and to further explore the association between sarcopenia and metabolic syndrome （MS）.
Methods A total of 1 438 middle-aged and elderly people （aged≥50 years） in Urumqi from July 2018 to January 2019 were selected as the research subjects. Data were collected by questionnaire survey， physical examination and laboratory test. Skeletal muscle mass，grip strength and 4 m walking speed were used to represent muscle mass， muscle strength and body function， respectively. Bioelectrical impedance analysis （BIA） was used to measure human body components. Based on the diagnostic criteria of sarcopenia recommended by AWGS2019， the prevalence of sarcopenia in people over 50 years old was obtained. Multivariate logistic regression model was used to explore the correlation between sarcopenia and MS in middle-aged and elderly people of different genders.
Results There were 194 patients with sarcopenia， with a prevalence of 13.49%. The prevalence was 15.56% in males and 12.12% in females. There was no significant difference in the prevalence of MS between male sarcopenia group （40.45%） and non-sarcopenia group （38.92%）， while the prevalence of MS in female sarcopenia group （39.04%） was higher than that in non-sarcopenia group （27.56%）. Multivariate logistic regression analysis showed that sarcopenia was a related factor of MS. Compared with non-sarcopenia， the risk of MS in male sarcopenia group was higher （OR=2.11，95%CI： 1.15‒3.88 ）.
Conclusion Sarcopenia increases the risk of MS in middle-aged and elderly people， with a greater risk in men. Fully understanding of sarcopenia is helpful to early identify high-risk groups of MS and prevent the occurrence of MS.
