9 Objective 1 To determine natural history and rate of GFR decline per year of Thai SEEK CKD patients 2 To identify the predictors of CKD progression in Thai SEEK CKD patients 3 To estimate incidence of CKD and Etiology in Thai SEEK non-CKD population 4 To identify the risk factors of incident CKD in Thai SEEK non-CKD population

10 Methods A prospective cohort study was performed among 3,459 Thai SEEK subjects during June 16, 2015 to December 15, 2016. History, physical examination, standardized serum creatinine measurement, urinalysis, and urine albumin creatinine ratio (UACR) were assessed in order to determine The incident CKD (UACR>30 mg/g or RBC > 5/HPF or eGFR < 60 ml/min/1.73m2) CKD progression (changed in CKD stage plus GFR decline > 25% or rate of GFR decline > 5 ml/min/1.73m2/year or received renal replacement therapy). Information of death was retrieved in whom was die during follow-up period.

32 Conclusion During 8 years follow-up, the overall incidence of CKD was 28% and abnormal microalbuminuria was the major contributor for CKD diagnosis. The main nephrologist diagnosis of CKD were hypertensive nephropathy and glomerular disease which contributed about 50% of diagnosis. Among subject with CKD, risk for CKD progression was 23% and the rate of GFR decline per year were different according to CKD stages. Factors associated CKD progression were DM and hyperuricemia while hypertension, DM and low income were associated with incident CKD. CKD stage showed dose-response associated with death.
