Abstract:
ObjectiveTo investigate and compare the prevalence,awareness and risk factors of chronic kidney disease (CKD) between urban and rural population in Guangxi province in order to provide information for prevention and treatment of CKD.MethodsBy a stratified multistage random sampling method,18 to 74 years old residents in Guangxi province were surveyed. They wereevaluatedbyquestionnaire,urinaryalbumin/creatinineratio, hematuria (microscopic examination of centrifuged urine sediment),kidney B-mode ultrasound,and abnormal results were reviewed 3 months later.Estimated glomerular filtration rate(eGFR) was calculated with the simplified MDRD equation modified by a Chinese coefficient.The risk factors associated with CKD were also investigated.Results There were no significant differences between urban and rural residents in the prevalence of albuminuria (5.22％ vs 5.47％) and hematuria (1.07％ vs 1.11％)(all P＞0.05).The prevalence of renal lithiasis in rural residents was significantly higher than that in the town(10.54％ vs 6.95％)(P＜0.05).The decreased renal function between urban and rural residents(3.87％ vs 4.04％,P＞0.05) had no significant difference.The prevalence of CKD was 9.58％ in urban and 9.42％ in rural(P＞0.05).The prevalence of albuminuria according to the age distribution was different between urban and rural,which increased along with the age in urban but showed two peaks(30-40 years old and 60-74 years old) in rural.Based on logistic regression analysis,the risk factors for albuminuria were diabetes,hyperuricemia,the history of cardiovascular disease,chronic tonsillitis and HBsAg positive.The risk factors for kidney function decline were age,hyperuricemia,hypertension,diabetes,renal lithiasis and history of cardiovascular disease.The awareness rate of CKD in urban was significantly higher than that in rural (14.45％ vs 6.27％,P＜0.05).Conclusions The prevalenceof CKD has no significant difference between urban and rural in Guangxi province.The awareness rate of CKD in urban is significantly higher than that in rural.It is needed to enhance the prevention and treatment of CKD in rural.
