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

Scientific Claim

Weight gain and waist increase are not significantly associated with all-cause mortality compared to stable weight or waist circumference in older adults (HR: 0.7 [0.4-1.5] and HR: 0.9 [0.4-1.6], respectively).

Original Statement

“Compared to those stable weight/waist, the mortality risk was similar in those of weight gain or waist increase (HR 0.7,95%CI: 0.4-1.5 and HR:0.9, 95%CI:0.4-1.6).”

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The claim correctly uses 'not significantly associated' and includes HRs and CIs, which is appropriate for an observational study.

Similar Assertions

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

81%

For older adults, both very small and very large changes in waist size are linked to higher death rates, forming a U-shaped pattern.

77%

Increased waist circumference is associated with a higher risk of metabolic disease and mortality, independent of total body weight.

76%

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.

74%

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.
