Anemia and Kidney Function Decline among the Middle-Aged and Elderly in China: A Population-Based National Longitudinal Study

Table 3

Multivariate logistic regression analysis for the association between anemia/hemoglobin and rapid decline in kidney function^a.

Variable	Adjusted OR^b	95% CI	value
Anemia
Male	1.72	1.24–2.39	0.001
Female	1.66	1.24–2.23	0.001
Total	1.64	1.32–2.04	<0.001
Hemoglobin (per 1 g/dL)
Male	0.92	0.87–0.97	0.003
Female	0.87	0.82–0.92	<0.001
Total	0.90	0.87–0.94	<0.001

Note: ^arapid decline in kidney function was defined as the percentage of decrease in eGFR exceeded quartile 3 (16.9%) from 2011 to 2015. ^bThe models were adjusted for age, sex (only in the “total” model), residence, education, medical insurance, personal consumption expenditure, smoking, drinking, body mass index, central obesity, C-reactive protein, cardiovascular disease, hypertension, diabetes, hyperuricaemia, and baseline eGFR. Abbreviations: CI: confidence interval; eGFR: estimated glomerular filtration rate; OR: odds ratio.
