Grip Strength Predicts Women's Longevity
A study found that for older women, grip strength may be the best single predictor of longevity. Researchers suggest that simple measures of muscular strength are as important to track as blood pressure in routine health checks.
- A landmark study called the Prospective Urban Rural Epidemiology (PURE) study, which followed over 140,000 adults, found that grip strength was a stronger predictor of all-cause and cardiovascular mortality than systolic blood pressure. For every 5-kilogram decrease in grip strength, there was a 16% increase in the risk of death. - Grip strength is an indicator of overall muscle mass and strength, which is crucial for longevity. Higher muscle mass is associated with lower mortality rates, improved metabolic function, a stronger immune system, and greater cognitive resilience. - The measurement of grip strength is typically done with a handheld device called a dynamometer. Research has defined weak grip strength as less than 16 kg (35 pounds) for women. - Beyond predicting longevity, weaker grip strength is also linked to a higher risk of falls, fractures, and hospitalization. It can also be an indicator of other health issues like arthritis, cognitive decline, and diabetes. - A study focusing on women aged 63 to 99 found that those in the highest grip strength group had a 33% lower risk of death compared to those in the weakest group. For every roughly 15-pound increase in grip strength, the risk of death was reduced by 15%. - Grip strength reflects a person's biological age, not just their chronological age. Weaker grip strength has been associated with accelerated aging at a cellular level. - The connection between grip strength and longevity is not limited to women. Studies have shown a similar association in men. For men, a grip strength below 26 kg (57 pounds) is generally considered weak. - Improving overall muscle strength through resistance training can in turn improve grip strength. Just 30 to 60 minutes of muscle-strengthening exercise per week has been shown to increase life expectancy.
