[Background] The prevalence of obesity and hyperuricemia among adult residents is on the rise. However, the studies' results on the correlation between obesity and hyperuricemia are not consistent. [Objective] This study aims to explore the relationships of general obesity and central obesity with hyperuricemia among adult residents in four provinces of China.
