Dose-response relationship between visceral fat index and untreated hypertension in Chinese rural population: the RuralDiab study

摘要

The study aimed to explore the association of visceral fat index (VFI) with untreated hypertension in different genders and evaluate the practicability of VFI as a marker for discriminating untreated hypertension in Chinese rural population. A total of 12,536 eligible participants aged 35 years and older were derived from the RuralDiab study in China. VFI was assessed with bioelectrical impendence methods and divided into sex-specific quartiles. Logistic regression and restricted cubic spline regression were performed. Receiver operating characteristic curve was applied to analyze the discriminating performance of VFI. Meanwhile, a meta-analysis was conducted to validate the result of this study.
