Older Chinese people without high blood pressure who are overweight (BMI between 24 and 28) are less likely to die from any cause compared to those with a normal weight.

Scientific Claim

In older Chinese adults aged 60 and older without hypertension, overweight (BMI 24–28 kg/m²) is associated with a 11.6% lower risk of all-cause mortality (hazard ratio 0.884, 95% confidence interval 0.822–0.949) compared to normal weight (BMI 18.5–24 kg/m²).

Original Statement

In normotensive participants, the hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) of BMI <18.5, 24–28 and ≥28 kg/m² for mortality... were 1.444 (1.267–1.646), 0.884 (0.822–0.949) and 0.912 (0.792–1.051), respectively.

Assessment Explanation

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