ABSTRACT
To investigate the association between estimated glomerular filtration rate (eGFR) and all-cause mortality in the elderly aged 65 years and older in longevity areas in China. Data used in this study were obtained from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey, 1 802 elderly adults were collected in the study during 2012-2017/2018. In this study, the elderly were classified into 4 groups, moderate-to-severe group [<45 ml·min(-1)·(1.73 m(2))(-1)], mild-to-moderate group [45- ml·min(-1)·(1.73 m(2))(-1)], mild group [60- ml·min(-1)·(1.73 m(2))(-1)] and normal group [≥90 ml·min(-1)·(1.73 m(2))(-1)] according to their eGFR levels. After 6 years of follow-up, 852 participants died, with a mortality rate of 47.3. Multivariate Cox regression analysis showed that the levels of eGFR were negatively correlated with all-cause mortality risk in the elderly (the of elderly was 0.993 and the 95 was 0.989-0.997 for every unit of eGFR increased, =0.001), while compared with the group with normal eGFR, the (95) of the elderly in the moderate-to-severe group, mild-to-moderate group, and mild group were 1.690 (1.224-2.332, =0.001), 1.312 (0.978-1.758, =0.070), 1.349 (1.047-1.737, =0.020) respectively [trend test <0.001]. The decrease in eGFR was associated with higher mortality risk among the elderly in longevity areas in China.
