The Claim
Relative muscle strength, defined as handgrip strength normalized to body weight, is weakly associated with all-cause mortality in middle-aged and older adults, with hazard ratios of 1.62 in men and 1.71 in women when comparing the lowest to the highest quartile of strength, but these associations are not statistically significant in fully adjusted models, suggesting limited independent predictive value beyond conventional risk factors.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're an older adult, having weaker hand grip compared to your weight might be a little linked to a higher chance of dying from any cause, but it doesn't add much info beyond things like blood pressure or smoking.
See the scientific wording
Relative muscle strength, measured as handgrip strength adjusted for body weight, is weakly associated with all-cause mortality in middle-aged and older adults, with hazard ratios of 1.62 in men and 1.71 in women for the lowest versus highest quartile, and non-significant p-values in fully adjusted models, indicating limited independent predictive value beyond conventional risk factors.
What the research says
1 studyStudy: Muscle Power Versus Strength as a Predictor of Mortality in Middle-Aged and Older Men and Women.
The study looked at handgrip strength relative to body weight and found it only weakly linked to survival, just like the claim says, and not strong enough to predict death on its own.
