Abstract:
Objective To investigate the prevalence of chronic kidney disease (CKD) and its risk factors in Chinese elderly persons.Methods All of the people who underwent physical examination and treatment in the geriatric department of Beijing Hospital during January 2004 to January 2007 were included in the study.Age, body height, body mass index and blood pressure were recorded.Bloody urine was ascertained by phase-contrast microscope, and urine protein was measured by dipstick test.The hemoglobulin, serum eretinine, blood urea nitrogen, blood lipid and serum uric acid were measured by autobiochemical analyzer.HbsAg was checked by enzyme-linked immunosorbent assay (ELISA).Glomerular filtration rate (GFR) was estimated by Crockeroft-Gauh equation and abbreviated MDRD equation.Binary logistic regression analysis was used to test the risk factors for proteinuria and CKD.Results The prevalence of proteinuria was 4.9% in 1082 elderly persons.And 47.23% of the elderly suffered from decreased renal function.The morbidity of CKD was 48.43%.Binary logistic regression analysis showed that diabetes(OR= 2.257) and microscopic hematuria(OR=5.324) were the risk factors of proteinuria (both P<0.05).And the risk factors for CKD were hypertension(OR= 1.459), coronary arth'erosclerotic heart disease(OR=3.290), chronic obstructive lung diseases(OR=2.094), malignant tumor(OR=2.072), hyperuricemia(OR= 1.928),anemia(OR=8.122)and hematuria( OR= 1.604) (all P<0.05).Conclusions The morbidity of CKD in Chinese elderly persons was 48.43%.And the related risk factors were diabetes,hypertension, hyperuricemia, coronary artherosclerotic heart disease and chronic obstructive lung disease.
