Being underweight, overweight, or obese at the start of the study didn't significantly change the risk of death compared to having a normal weight in older adults.

Scientific Claim

Baseline underweight, overweight, and obesity categories are not significantly associated with all-cause mortality compared to normal BMI in older adults (HRs: underweight 1.7 [0.7-4.0], overweight 0.7 [0.4-1.2], obesity 1.3 [0.8-2.3]).

Original Statement

“Compared to normal BMI at baseline, the association between underweight (HR: 1.7, 95% CI: 0.7-4.0), overweight (HR:0.7, 95% CI:0.4-1.2) and obesity (HR:1.3,95% CI:0.8-2.3) showed insignificantly associated with all-cause mortality.”

Assessment Explanation

The claim accurately states the lack of significant association using HRs and CIs, which is appropriate for an observational study.

Older Chinese people without high blood pressure who are obese (BMI 28 or higher) do not have a significantly different risk of dying from any cause compared to those with a normal weight.

80%

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.

76%

Older Chinese people with high blood pressure who are obese (BMI 28 or higher) are less likely to die from any cause compared to those with a normal weight.

75%

Older adults who lose more than 5% of their body weight are more likely to die within the study period compared to those whose weight stays stable.

75%

Gaining weight or increasing waist size didn't significantly affect the risk of death compared to stable weight or waist size in older adults.
