Key summary points Aim  To assess the prevalence of sarcopenia and its related factors using the 2019 diagnostic criteria of sarcopenia recommended by the Asian Working Group for Sarcopenia (AWGS) among residents who lived in a veterans’ home. Findings  The prevalence of sarcopenia was high (66.9%, n = 93). After adjusting for age, low body mass index (BMI) and low Barthel Index (BI) scale score were significantly predictive of sarcopenia, but the mini-mental state examination (MMSE) scales and Lawton and Brody Instrumental Activities of Daily Living scales (IADL) scores not. Message  Sarcopenia is highly prevalent in the present sample. Health providers should pay more attention to residents who have low BMI and impaired basic activities, because they tend to suffer from sarcopenia. Abstract Background  Older adults are more likely to experience the disorder of skeletal muscles. Objective  This study aimed to examine the prevalence of sarcopenia using the diagnostic procedures of sarcopenia recommended by the Asian Working Group for Sarcopenia in 2019. The association of sarcopenia with physical activity and other factors was also explored. Methods  A cross-sectional study was designed. The sample came from a veterans’ home in southern Taiwan during the months of July–September 2018. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia (AWGS) criteria in 2019. Skeletal muscle mass and grip strength were determined using bioelectrical impedance analysis and a digital dynamometer, respectively. The walking speed for a 6-m distance was also measured. Furthermore, the Barthel Index (BI), Lawton and Brody Instrumental Activities of Daily Living scales (IADL), mini-mental state examination (MMSE), and body mass index (BMI) were also collected. Results  Overall, 139 men with a mean age of 84.3 years (± 10.3 years) were analyzed. According to the recommendation of the AWGS in 2019, the prevalence of sarcopenia was 66.9% (n = 93), whereas 55.4% (n = 77) of men were determined to have severe sarcopenia. After adjusting for age, BMI (OR 0.63, 95% CI 0.53–0.75, p
