Muscle strength and uric acid: links to earlier death faded after adjustment

If you have heard that grip strength and uric acid can say something about how long you will live, here is the calmer version. A study of older adults found that weak muscle strength and high uric acid both looked linked to earlier death at first. Once the researchers took other health factors into account, those links faded.

That fading is useful to know. It suggests grip and uric acid may be signs of overall health, not single causes of anything. And muscle strength is something you can work on at any age.

How the study worked

Researchers looked back at the records of 910 people aged 60 or older seen at a university hospital between 2020 and 2024, and followed who died. The average age was 71, and 66.9% were women. The results were published Sept. 15, 2026, in Metabolic Syndrome and Related Disorders, and because it looked back at records from one hospital, it shows patterns, not cause and effect.

What they found

The team measured handgrip strength, which is how hard you can squeeze a device. They also measured muscle mass and uric acid in the blood, and sorted people into four groups by uric acid level.

At first glance, the picture looked worrying. People with weak grip were about twice as likely to die during the study (1.91 times). People in the highest uric acid group were also about twice as likely (1.86 times). Both weak grip and high uric acid went along with less healthy metabolic readings, such as those that track how the body handles sugar and fat.

Then came the part that matters most. After the researchers adjusted for other factors, both links faded. In plain words, the weak grip and the high uric acid were no longer standing out on their own as predictors of death.

There was one exception. When the researchers looked at men and women separately, high uric acid still stood out among women. Women with high uric acid were about three times as likely to die during the study (3.08 times). That does not mean uric acid caused it. It means doctors may want to pay closer attention to this number in older women.

What are grip strength and uric acid, anyway?

Grip strength is a quick, simple test. It reflects the strength of your muscles overall, not just your hands. Doctors often use it as a snapshot of how well the body is holding up.

Uric acid is a waste product your body makes. When levels run high, it can cause gout, a painful joint condition. It shows up on many routine blood tests, so there is a good chance your doctor already has your number.

What you can do today

You do not need a gym or any special gear to start building the strength this study measured. Grab a soft ball or a rolled-up towel and squeeze it hard for five seconds. Rest a moment, then repeat until you have done ten squeezes with each hand. It takes a couple of minutes, and you can do it right now with your coffee in the other hand.
