Abstract: ObjectivesExcess sugar consumption, particularly in sugar-sweetened beverages (SSBs), has been linked to poor cognitive performance. We aimed to assess the association of consumption of total sugar, as well as the consumption of SSBs, solid desserts, and 100% fruit juice with cognitive performance among older adults.MethodsConsumption of total sugar, SSBs, solid desserts, and 100% fruit juice were obtained from the 24-hr recall interview. Cognitive performance was evaluated using the Consortium to Establish a Registry for Alzheimer’s Disease word list, the Animal Fluency Test, and the Digit Symbol Substitution Test. Binary logistic regression models were used to evaluate the association between consumption of sugar (total and from different sources) and cognitive performance.ResultsA total of 1,938 participants aged 60 years or older from the National Health and Nutrition Examination Survey 2011–2014 were included. Compared to the lowest tertile, the highest tertile of total sugar consumption was independently associated with higher odds of low memory performance (odds ratio [OR] = 1.87, 95% confidence interval [CI] = 1.00; 3.50, p = .049). Consumption of SSBs was associated with higher risk of low memory (OR = 1.58, 95% CI = 1.11; 2.25, p = .014), whereas consumption of solid desserts was associated with lower risk of low verbal fluency performance (OR = 0.62, 95% CI = 0.41; 0.95, p = .032).DiscussionHigher consumption of total sugars and SSBs was associated with lower memory performance, while consumption of solid desserts was associated with higher verbal fluency performance.
