A total of 4000 community‐dwelling older adults aged ≥65 years were evaluated for which detailed information regarding demographics, socioeconomic, medical history, lifestyle, and clinical factors were documented at baseline, 2 years, and 4 years later.

At baseline, of the 4000 participants, 361 (9.0%) had sarcopenia. Between baseline and 2‐year follow‐up, 6.0% of the participants without sarcopenia at baseline had developed sarcopenia, and 18.8% of the initially sarcopenic participants had reverted to normal …
