Association of combined left and right handgrip strength with new-onset chronic kidney disease in middle-aged and older adults: a nationwide multicenter cohort study.

Background: The role of multi-site muscle strength in the incidence of chronic kidney disease (CKD) remains largely unknown. This study aims to investigate the association of combined left and right handgrip strength (CHS) with new-onset CKD in middle-aged and older adults.

Methods: This observational multicenter study included 4618 community-dwelling adults without CKD at baseline in 2011.
