The application value of SARC-F combined with calf circumference,grip strength,and vitamin D measurement in screening for sarcopenia in the elderly population in the community
Objective To explore the application value of simple five item scoring scale(SARC-F)combined with calf circumference,grip strength,and vitamin D measurement in screening for sarcopenia in the elderly population in the community.Methods A total of 180 elderly people in the community were selected as the study subjects,and the subjects were examined for sarcopenia.According to the diagnostic criteria for sarcopenia issued by the Asia Working Group for Sarcopenia(AWGS),the elderly population was divided into the sarcopenia group(n=70)and the non-sarcopenia group(n=110).The positive rate of SARC-F,calf circumference,grip strength and vitamin D level were detected and compared between the two groups.Multivariate logistic regression was used to analyze the independent risk factors affecting the occurrence of sarcopenia in the elderly.The risk assessment model was established by assigning values according to the influencing factors.The diagnostic efficiency of the model was evaluated by receiver operating characteristic(ROC)curve.Results The sarcopenia group had higher positive rate of 68.57% than 19.09% in non-sarcopenia group;the sarcopenia group had calf circumference of(31.48±4.72)cm and grip strength of(17.25±2.58)kg,which were lower than(35.47±5.32)cm and(25.11±3.76)kg in non-sarcopenia group;the sarcopenia group had lower vitamin D of(16.43±2.46)ng/ml than(22.56±3.38)ng/ml in non-sarcopenia group;the difference was significant(P<0.05).Multivariate Logistic regression analysis showed that SARC-F positivity,calf circumference,grip strength and vitamin D level were independent risk factors for sarcopenia in the elderly(OR=4.229,1.078,2.578,2.050;P<0.05).According to the ROC curve analysis,the area under the curve(AUC)of the established risk assessment model(i.e.,under the combined testing model of ARC-F positivity,calf circumference,grip strength,and vitamin D)was the highest,which was 0.998,and the sensitivity and specificity were 98.14% and 94.44% ,respectively.Conclusion SARC-F combined with calf circumference,grip strength and vitamin D measurement has high clinical application value in the screening of sarcopenia in the elderly population in the community,and has the advantages of simple operation,which is worthy of promotion and application.
