RESUMO
Objectives: To explore the relationship between body fat indexes and hypertension levels by quantitative CT (QCT) study. Methods: A total of 1488 participants from "prospective urban-rural epidemiology (PURE) study" were enrolled. The participants' age were from 42 to 82 years; based on blood pressure (BP) they were divided into 2 groups: Non-hypertension group, n=783 and Hypertension group, n=705. QCT fat measurement software was used to examine L2 level abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT); body mass index (BMI), waist circumferences (WC), hip circumferences (HC) and waist-to-height ratio (WHtR) were measured and calculated; liner Logistic regression analysis and 2-classified Logistic analysis were conducted to study the relationships between hypertension and anthropometric indices, abdominal VAT, SAT respectively. Results: Compared with Non-hypertension group, Hypertension group had increased BMI, WC, HC, WHtR, abdominal VAT and SAT, P<0.05. BMI, WC, HC, WHtR, abdominal VAT and SAT were related to both systolic BP (SBP) and diastolic BP (DBP), P<0.05. Multivariable Logistic regression analysis indicated that WHtR, abdominal VAT, SAT were the independent impact factors of SBP and WC, abdominal VAT were the independent impact factors of DBP; further investigation showed that abdominal VAT and WC were the independent impact factors of hypertension. Conclusions: Abdominal VAT was robustly related to hypertension in Chinese population, it might be helpful for risk stratification in hypertension patients.
