Nutritional Profile and Serum Uric Acid are Associated withMetabolic Syndrome in Community-dwelling Older Adults:A Cross-sectional Study

Abstract

Objective: This study aimed to evaluate the prevalence of metabolic syndrome in community-dwelling older adults and compare the nutritional profile in macronutrient and micronutrient intakes and serum uric acid in community-dwelling older adults with and without metabolic syndrome.Materials and Methods: Overall, 155 community-dwelling older adults were enrolled and were stratified into two groups: with and without metabolic syndrome. The estimated daily macronutrient and micronutrient intakes and the single umbilical artery (SUA) were obtained and compared between the groups.Results: The prevalence rate of metabolic syndrome was 38.7%, and older adults with metabolic syndrome exhibited greater carbohydrate and lower protein and lipid consumptions. It was observed that the older adults without metabolic syndrome showed higher daily mono- and poly-unsaturated fatty acids, copper and vitamins A and B6 intakes, whereas those with metabolic syndrome exhibited higher daily manganese and vitamin C intakes. Higher SUA was found in older adults with metabolic syndrome, characterising a pro-oxidant state.Conclusion: The nutritional profile adopted by older adults with metabolic syndrome may induce the development of a worrying pro-oxidant state. High carbohydrate consumption could blind the protective effect of a high antioxidant micronutrient intake.
