The Claim
In Chinese adults aged 20–69, a one interquartile decrease in relative handgrip strength (handgrip strength divided by body weight) is associated with a 43% to 58% higher prevalence of hypertension, defined as systolic blood pressure ≥140 mmHg or diastolic ≥90 mmHg.
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 Chinese adults aged 20–69, lower handgrip strength relative to body weight is associated with a higher prevalence of hypertension, defined as systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg.
See the scientific wording
In Chinese adults aged 20–69, a one interquartile decrease in relative handgrip strength (handgrip strength divided by body weight) is associated with a 43% to 58% higher prevalence of hypertension, defined as systolic blood pressure ≥140 mmHg or diastolic ≥90 mmHg, across four national surveys from 2000 to 2014 involving 712,442 individuals, suggesting that lower muscle strength relative to body size is consistently linked to elevated blood pressure risk in this population.
When muscles are weaker relative to body size, they burn less sugar and fat during daily activity, causing fat to build up in blood vessels and around organs. This makes blood vessels stiff and narrow, forcing the heart to pump harder, which raises blood pressure.
What the research says
1 studyPeople in China with weaker hand strength relative to their body weight were found to be much more likely to have high blood pressure — about 43% to 58% more likely for each typical drop in strength compared to others.
