ABSTRACT
Objective To investigate the epidemiology of chronic kidney disease (CKD) in patients with hypertension and diabetes mellitus in Kunming urban area.Methods A multistage cluster randomized sampling method was used to collect 400 randomly selected patients (community managed hypertension and diabetes mellitus) in community service centers in the 4 main urban districts of Kunming,Yunnan province.The subjects were screened for CKD by questionnaires,physical examinations,and microalbuminuria tests.Results A total of 343 people were surveyed.The prevalence of albuminuria,proteinuria by routine urinalysis,decreased glomerular filtration rate,and CKD prevalence were respectively 37.3％,12.2％,5.0％ and 39.1％.A total of 134 patients with CKD (134/343) were screened.Logistic regression analysis showed male (OR=2.312,95％CI 1.325-4.037,P=0.003),hyperuricemia (OR=1.751,95％ CI 1.109-2.765,P=0.016) and obesity (OR=2.150,95％ CI 1.115-4.146,P=0.022) were related to CKD.Conclusions The prevalences of CKD and albuminuria are 39.1％ and 37.3％ in patients with chronic diseases (hypertension and diabetes) in the main urban community of Kunming,Yunnan.Hyperuricemia,male and obesity are independent risk factors for CKD.
