ABSTRACT
Objective:To determine the prevalence of renal function decline in the elderly population in a community and risk factors. Methods:Data in the physical examination of the elderly population aged over 60 years old in a community in 2018 were collected and analyzed. Estimated glomerular filtration rate was calculated by modified modification of diet in renal disease （MDRD） formula. Association between renal function decline and risk factors were determined. Results:Among the 9 626 elderly people， the prevalence of renal function decline was 10.71%， which increased with age. Multivariate logistic regression showed that men， age， anemia， abnormal uric acid， hypertension， hyperlipidemia， diabetes， glutamine transaminase， and the history of stroke were the independent risk factors associated with renal function decline. Conclusion:The prevalence of renal function decline in elderly people in a community in Shanghai is relatively high. It is necessary to pay attention to early screening and take effective preventive measures， such as health education， scientific exercise and reasonable diet， chronic disease management and other measures.
