High prevalence of metabolic syndrome in a middle-aged and elderly population with prehypertension in Tianjin

AbstractBackground: Prehypertension has been reported as being correlated with future cardiovascular risk and end-organ damage in middle-aged and elderly persons, and also playing an important role in metabolic syndrome (MetS). The association between prehypertension and MetS has rarely been reported among urban adults in Tianjin, China. Methods: In this cross-sectional study, a total of 1176 participants aged 40–70 years (524 males and 652 females) were enrolled after excluding participants with hypertension or treated hypertension. Participants were divided into two groups [optimal blood pressure (BP) and prehypertension] based on the classification of BP from the JNC-7.

Results: The prehypertension group had a significantly higher odds ratio (OR) than the optimal BP group for abnormal waist circumference (WC), fasting ...
