Association of 6-year waist-circumference change with progression from prehypertension to hypertension: the Rural Chinese Cohort Study

Whether dynamic change in waist circumference is associated with progression from prehypertension to hypertension is not well understood. We explored this issue. A total of 4221 prehypertensive adults ≥18 years were enrolled during 2007–2008 and followed up during 2013–2014. Participants were classified by percentage waist-circumference change at follow-up: ≤−2.5, −2.5 to ≤2.5, 2.5 to ≤5.0, and >5.0%. Odds ratios (ORs) and 95% confidence...
