For how we live.
Applying the clinical-versus-preclinical obesity framework to 2,316 surgical patients in four countries found two groups near-identical on BMI and different on almost everything else.
A Swiss cohort was classified by WHO, NIH and EASO criteria at the same time. The share of people with obesity roughly doubled, and the overweight category shrank to fill the gap.
A Qatar Biobank analysis derived local cut-points and found WHO's standard numbers misclassified more than half of men and nearly half of women in the sample.
A 20-point rise in apnea severity tracked with about three times more blood pressure increase in adults with a BMI of 20 than in those with a BMI of 30, flipping a common assumption.
In 3,873 middle-aged adults followed with repeated testing, waist-based categories of overweight and obesity showed larger effect sizes than BMI-based ones. The link to actual decline appeared only in men.
Nearly a million conscripts followed for three decades: obesity carried a 3.1-fold hazard for sepsis, and high cardiorespiratory fitness was associated with a 42% lower risk of dying from bacterial infection.
