The COVID-19 pandemic exposed older adults to high risk of sarcopenia. This study aimed to investigate the prevalence of sarcopenia and its risk factors among Japanese community-dwelling older adults during the COVID-19 pandemic. We collected data through questionnaires and physical measurements among 242 older adults. Sarcopenia was assessed using the Asian Working Group for Sarcopenia 2019 criteria. The results revealed that 14.5% had sarcopenia, which was significantly associated with age, nutritional status, number of prescription medications, body mass index, and self-rated health. On multivariate analysis, the risk of malnutrition was independently significantly associated with sarcopenia. Approximately 70% of participants reported decreased social interaction and going outside, but with no significant association with sarcopenia. In addition, approximately 65% of the participants had an exercise habit and went outside at least once a week, thus maintaining a good level of activity. These findings suggest that prevention of sarcopenia during the pandemic required provision of opportunities for older adults to remain active and positive assessment of nutritional status and well-being.
