OBJECTIVE: To compare the diagnostic accuracy of possible sarcopenia identification pathways, as suggested by Asian Working Group for Sarcopenia (AWGS) in 2019, by gender among Korean community-dwelling older adults. DESIGN: Cross-sectional analysis of data from 2,129 community-dwelling adults (70-84 years, 50.4% men) enrolled in Korean Frailty and Aging Cohort Study. METHODS: Based on AWGS 2019 guideline, possible sarcopenia was defined by low handgrip strength (HGS) or slow five-times chair stand test (5CST) time, referred to as "assessments." "Case-findings" (low calf circumference [CC], SARC-F ≥4, or SARC-CalF ≥11) were recommended for screening 'possible sarcopenia' before assessment. For the six 'possible sarcopenia' pathways (combining three case-finding and two assessment tools), area under the curve (AUC) and F RESULTS: For case-finding in men, CC demonstrated the highest AUC (0.657) and F CONCLUSIONS: Based on AWGS 2019 guideline, CC in men and SARC-CalF in women was the best case-finding tool for community-dwelling older adults. After the best case-finding in each gender, two assessment pathways demonstrated insignificant difference in both genders. BRIEF SUMMARY: For case-finding of possible sarcopenia, using calf circumference in older men and using SARC-CalF in older women demonstrated the highest diagnostic accuracy for predicting sarcopenia. After the best case-finding in each gender, two assessment pathways (handgrip strength and five-times chair stand test) of possible sarcopenia demonstrated insignificant difference in both genders.
