Abstract

Examine the association between glycemic control and cognition. Included subjects ≥60 years who participated in the 2013 to 2014 National Health and Nutrition Examination Survey and completed one of the followings: Consortium to Establish a Registry for Alzheimer’s Disease Word List (CERAD-WL), Animal Fluency (AF), Digit Symbol Substitution Test (DSST), and CERAD-Delayed Recall (CERAD-DR). Stratified participants into: No type 2 diabetes (T2D; N = 557), Controlled T2D (N = 41), Uncontrolled T2D (N = 120), and Untreated T2D (N = 86). Multiple regression was used to examine the association between variables. After adjusting for demographics and cardiovascular risk factors, Uncontrolled T2D was associated with lower DSST (β = −3.164, p =.04), and Untreated T2D was associated with a trend for having lower CERAD-DR (β = −.496, p =.06) scores. T2D, independent of glycemic control, is associated with cognitive impairment and this relationship is influenced by modifiable and non-modifiable risk factors.
