We performed a large-scale cross-sectional study in 3359 participants on AMOL cohort in 2016. All demographic data, blood and urine samples were collected during the interview. Albumin to creatinine ratio was measured in all cases and if more than 30 mg/g, the results were confirmed by 24 hours urine for albumin. CKD definition was urine albumin more than 30 mg/24 hours or GFR less than 60 CC/minute based on CKD-EPI formula.
