Handgrip strength and health outcomes: Umbrella review of systematic reviews with meta-analyses of observational studies

Highlights • We carried out an umbrella review of systematic reviews with meta-analyses of observational studies on handgrip strength and all health outcomes. • Three outcomes (lower all-cause mortality, lower cardiovascular mortality, and lower risk of disability) were found to have highly suggestive evidence. • One outcome (chair rise performance over time) was found to have suggestive evidence. • Five outcomes (walking speed, inability to balance, hospital admissions, cardiac death, and mortality in those with chronic kidney disease) were found to have weak evidence.
