The Claim

Higher relative handgrip strength is inversely associated with hypertension across subgroups of normal weight, overweight, and obese individuals, indicating that this association is independent of body mass index.

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.

In plain English

People with stronger handgrips relative to their body size have lower rates of hypertension, regardless of whether they are normal weight, overweight, or obese.

See the scientific wording

The inverse association between relative handgrip strength and hypertension was consistent across subgroups including normal weight, overweight, and obese individuals, indicating that the relationship is not dependent on overall body mass index.

Why this might work

Stronger hand muscles signal the body to maintain relaxed blood vessels and lower nerve-driven stress responses, which keeps blood pressure stable regardless of body weight.

    Even if people are thin, overweight, or obese, those with weaker handgrips were still more likely to have high blood pressure — meaning muscle strength matters for blood pressure no matter your weight.
