Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in the adult urban population of Hezhou Guangxi. Methods One thousand and two hundred urban residents (older than 18 years) from Hezhou Guangxi were randomly selected using a random sampling. All the residents were interviewed. Their morning spot urine were tested to determine albumin to ereatinine ratio (abnormal:≥30 mg/g), and renal function [abnomal: eMDRD <60 ml·min-1·(1.73 m2)-1] was assessed. Morning spot urine dipstick of hematuria (abnormal:≥1 +) was confirmed by microscopy (abnormal: 3 red blood cells/HP). The associations among demographic characteristics, health eharacteristies and indicators of kidney damage were examined. Results Eligible data of 1069 subjects were enrolled in the study. The prevalence of albuminuria was 7.5%, hematuria 4.8%, and reduced eGFR 3.6%. The prevalence of kidney disease was 14.4% and the recognition was 1.4%. Age (OR 1.022, 95%CI 1.008-1.035), gender (OR 2.249, 95%CI 1.502-3.367), diabetes mellitus (OR 7.422, 95%CI 3.985-13.825) and hypertension (OR 4.397, 95% CI 2.601-7.432) were independently associated with CKD. Conclusions The prevalence of chronic kidney disease is 14.4% and the recognition is 1.4% in adult urban population of Hezhou Guangxi. Independent risk factors associated with chronic kidney disease are age, gender, diabetes mellitus and hypertension which is similar to those in developed countries and domestic big cities.
