RESUMO
Objective@#To investigate the risk factors of sarcopenia among the elderly, so as to provide insights into prevention of sarcopenia among the elderly.@*Methods@#A case-control study was conducted. A total of 371 patients with sarcopenia at ages of 60 years and older admitted to the First Affiliated Hospital of Xinjiang Medical University were selected as the case group, while 1∶1 matching healthy volunteers by gender, age and ethnicity in the hospital during the study period served as controls. Participants' demographics, disease history and nutrition were collected using questionnaire surveys, and factors affecting the development of sarcopenia were identified using a multivariable conditional logistic regression model. @*Results@#Participants in the case group included 171 men (46.09%), 254 Han ethnic populations (68.46%) and had a mean age of (73.04±7.83) years. Univariable conditional logistic regression analysis showed that participants with smoking, alcohol consumption, hypertension, diabetes, dyslipidemia, thyroid dysfunction and malnutrition had higher risk of developing sarcopenia (all P<0.05). Multivariable conditional logistic regression analysis identified hypertension (OR=1.851, 95%CI: 1.344-2.549), diabetes (OR=1.537, 95%CI: 1.068-2.213), dyslipidemia (OR=1.542, 95%CI: 1.112-2.140) and thyroid dysfunction (OR=2.575, 95%CI: 1.838-3.609) as risk factors of sarcopenia among the elderly. @*Conclusion@#Hypertension, diabetes, dyslipidemia and thyroid dysfunction may be risk factors of sarcopenia among the elderly.
