Correlation between Skeletal Muscle Mass Index and TG/HDL-C in Hospitalized Elderly
Objective:To analyze the correlation between skeletal muscle mass index(ASMI)and TG/HDL-C in hospitalized el-derly patients.To evaluate the predictive value of TG/HDL-C for low ASMI in elderly hospitalized patients.Methods:A total of 299 hos-pitalized elderly patients admitted to the First Hospital of Lanzhou University from July 2022 to August 2023 were selected and divided into low ASMI group(105 cases)and normal ASMI group(194 cases)according to the consensus on the diagnosis and treatment of sar-copenia issued by the Asian Working Group on sarcopenia in 2019.Clinical data of the two groups were compared,Spearman correlation analysis was used to study the correlation between ASMI and related variables,and multi-factor Logistic regression was used to analyze the influencing factors of ASMI.the predictive value of TG/HDL-C in the occurrence of low ASMI in elderly hospitalized patients was evaluate by receiver operating characteristic(ROC)curve.Results:With the increase of ASMI,TG/HDL-C ratio increased(P＜0.001).Spearman correlation analysis showed that ASMI was positively correlated with waist-to-hip ratio,basal metabolism,muscle,grip strength,body fat percentage,BMI,ALT,TG,TG/HDL-C,and negatively correlated with HDL-C(P＜0.05).Multifactor analysis showed that body fat percentage,uric acid and TG/HDL-C were independent influencing factors of ASMI.ROC curve showed that the area under TG/HDL-C curve was 0.67(95％CI:0.607～0.722).Conclusion:High TG/HDL-C was protective factors for low ASMI.TG/HDL-C has certain predictive value for the occurrence of low ASMI,and it is easy to estimate skeletal muscle mass by simple and easily obtained lipid indexes,so early monitoring and intervention can be carried out for patients with suspected sarcopenia.
