Older Chinese people without high blood pressure who have a larger waist size (over 90 cm for men or 85 cm for women) are slightly less likely to die from any cause compared to those with normal waist size.

Scientific Claim

In older Chinese adults aged 60 and older without hypertension, central obesity (waist circumference ≥90 cm in men or ≥85 cm in women) is associated with an 8.2% lower risk of all-cause mortality (hazard ratio 0.918, 95% confidence interval 0.846–0.996) compared to normal waist circumference.

Original Statement

Compared with normal waist circumference, the adjusted HRs and 95% CIs of central obesity for mortality were 0.880 (0.832–0.931) in hypertensive participants and 0.918 (0.846–0.996) in normotensive participants.

Assessment Explanation

The study is observational, so causal language is inappropriate. The claim correctly uses 'associated with' and provides the HR and CI.
