- W4380883417 abstract "Abstract Background Several innate and environmental factors affect the rate and degree of cognitive decline with each factor representing a potentially valuable intervention point to slow progression of this decline. Serum urate, a product of purine metabolism and potent antioxidant, and weight loss have been associated with cognitive decline. The aim of this study was to determine the relation among urate, body weight, and their interaction with cognitive function. Methods In the context of a larger study, 133 adults aged 65‐80 at baseline (mean baseline age 72.7 years, 56.5% male) were recruited to participate in a double‐blind, randomized controlled trial. The Montreal Cognitive Assessment (MoCA) was administered to assess cognitive function. Those with MoCA scores >25 were considered cognitively typical, whereas those with MoCA scores below this threshold were deemed to be experiencing mild cognitive decline (MCD). The cognitively typical group was instructed to maintain their regular diet and served as a reference, whereas MCD groups were randomized to receive either 35mg lyophilized wild blueberries or dextrose (serving as control) daily in addition to their regular diet. MoCA, anthropometric measures, and serum were collected at baseline and repeated at 3 and 6 months. The statistical analysis was performed using MiniTab v.19. Results A regression‐based analysis showed that changes in serum urate were positively associated with changes in MoCA scores (ß = 0.94, SE = 0.47, p < 0.05) at 6 months. Groupwise analyses showed that changes in MoCA scores were not correlated with changes in urate or body weight in individuals with typical cognition or those in the blueberry group. However, in the control group, changes in serum urate (ß = 1.96, SE = 0.92, p<0.05), changes in body weight (ß = ‐0.31, SE = 0.13, p<0.05), and interaction between urate and body weight significantly impacted the change in MoCA scores. (ß = 0.663, SE = 0.20, p<0.05). Individuals with increased urate and decreased body weight showed less cognitive decline as compared to those who had weight gain and decreased urate. Conclusion Our findings show that changes in urate and body weight interact with each other to significantly impact changes in cognitive function." @default.
