Cognitive performance correlated with hemoglobin level in patients with chronic kidney disease: a data analysis from the National Health and Nutrition Examination Survey (NHANES) 2011- 2014.

ABSTRACT:

Introduction

Given the increased incidence of renal anemia and cognitive dysfunction in patients with chronic kidney disease (CKD), the association between hemoglobin levels and cognitive function in these patients remains elucidated. An optimal level of hemoglobin for the best cognitive performance in CKD has yet to be determined.

Methods

A retrospective cross-sectional study was conducted using data from 2011-2014 of the National Health and Nutrition Examination Survey (NHANES). Enrolled subjects for analysis were divided into the CKD and the non-CKD groups. The Animal Fluency Test (AF), Digit Symbol Substitution Test (DSST), Consortium to Establish a Registry for Alzheimer's Disease Word Learning Test (CERAD-WL) and Word List Recall Test (CERAD-DR) were used to evaluate c
