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.

Scientific Claim

Waist circumference decrease exceeding 5% is associated with higher all-cause mortality risk (HR: 1.7, 95% CI: 1.0-2.8) in older adults compared to stable waist circumference.

Original Statement

“The HR of those weight loss >5% (HR: 1.7, 95% CI: 1.1-2.8) and waist decrease >5% (HR: 1.7, 95% CI: 1.0-2.8) were higher than those of stable weight/waist +/- 5% over a 6-year period.”

Similar Assertions

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

84%

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

81%

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

79%

In heart disease patients, larger waist sizes are linked to higher risk of dying from heart-related causes, with the biggest risk in those with the largest waist measurements.

79%

People with heart disease who have the largest waist sizes have a 19% higher chance of dying from any cause compared to those with medium waist sizes.
