Higher mid-life hand grip strength is independently associated with significantly lower long-term all-cause mortality in initially healthy men, regardless of body mass index (BMI).
For long-term survival, prioritize building and maintaining muscle strength over simply managing body weight. Grip strength serves as a robust indicator of overall health and physiological reserve. Incorporate resistance training into your routine to improve strength, as this metric predicts mortality risk independently of your BMI.
In healthy middle-aged men, long-term mortality risk was associated with grip strength at baseline, independent of BMI.
Why this rating
Prospective cohort study with a 30-year follow-up, large sample size (n=6040), and adjustment for multiple confounders.
