RESUMO
Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in middle-aged and older adult population in Shanghai Pudong New District.Methods Two thousand residents aged 45 years and above were randomly selected for questionnaire survey and health check-up in Shanghai Pudong New District from July 2006 to October 2010.The laboratory examinations were also performed including the urine routine,urinary protein to creatinine ratio,serum creatinine,blood glucose and lipids.The glomerular filtration rate (eGFR) was estimated by simplified Chinese MDRD (modification of Diet in Renal Disease) equation.SPSS 13.0 statistical software was used for statistical analysis.Results Among 1905 residents who completed survey and examinations,the adjusted prevalence of albuminuria was 12.0％ (95％ CI:0.105-0.135) and of eGFR less than 60 ml · min-1 · 1.73 m-2 was 1.9％ (95 ％ CI: 0.172-0.213).The prevalence of CKD was 12.6％ (95 ％ CI: 0.112-0.142).Logistic regression analysis revealed that age (OR =1.043),hypertension (OR =2.272),diabetes mellitus (OR =1.233)and hyperuricemia (OR =1.003)were independently associated with CKD.Conclusions The prevalence of CKD in adult residents (≥45 years) from Shanghai Pudong New District is high.It is necessary to carry out early screening and to intervene risk factors of CKD in middle-aged and older residents.
