Grip Strength Predicts 9 Major Diseases in 155-Study Meta-Analysis

Non-communicable diseases account for roughly 74% of global deaths annually, yet many are preventable through early identification of modifiable risk factors. Muscular strength has emerged as a powerful, non-invasive health marker, but it has remained unclear which simple, field-based tests best predict the onset of specific long-term conditions—as opposed to mortality alone.

This landmark systematic review and meta-analysis searched seven major databases through November 2024, ultimately identifying 155 eligible cohort studies, 94 of which contributed quantitative data. The two primary tests evaluated were the handgrip strength (HGS) test (featured in 145 studies) and the 5-repetition chair-stand test (5-CST, featured in 36 studies). The adult populations studied spanned diverse age groups and demographic profiles worldwide.

For handgrip strength, adults in the highest versus lowest strength categories showed significantly lower odds of cardiovascular diseases (OR=0.73), type 2 diabetes mellitus (OR=0.79), musculoskeletal impairment (OR=0.65), disability (OR=0.57), anxiety (OR=0.79), depression (OR=0.70), cognitive decline (OR=0.57), dementia (OR=0.62), and Parkinson's disease (OR=0.53)—all statistically significant. A dose-response relationship was also observed: each 5 kg increase in grip strength was associated with reduced risk across most of these conditions, reinforcing the clinical relevance of even modest strength improvements.

The 5-repetition chair-stand test also demonstrated robust predictive value. Better performance was associated with lower odds of T2DM (OR=0.80), musculoskeletal impairment (OR=0.52), disability (OR=0.58), depression (OR=0.63), and dementia (OR=0.68). A continuous metric was also meaningful: every 1-second decrease in 5-CST completion time corresponded to 6% lower odds of musculoskeletal impairment.

These findings have direct implications for clinical practice. Both tests require minimal equipment, take under five minutes, and can be performed in primary care, community, or hospital settings. The authors argue they should be routinely integrated into health screening protocols—particularly for aging populations at risk of functional decline, cardiovascular events, or cognitive deterioration. That said, the overall quality of evidence ranged from very low to moderate per GRADE assessment, meaning results should be interpreted with measured confidence and further high-quality prospective research is warranted.
