Topical Area: Vitamins and Minerals
Objectives : The purpose of this study was to examine the association between intake of antioxidant vitamins and prevalence of metabolic syndrome among Korean adults.
Methods : Based on the data from the 2013~2016 Korea National Health and Nutrition Examination Survey (KNHANES), a total of 10,351 adults aged 19~64 years were included. Presence of metabolic syndrome was determined using the National Cholesterol Education Program Adult Treatment Panel Ⅲ criteria. Intakes of antioxidant vitamins (vitamin A, vitamin C, and vitamin E) were estimated by combining a 24-h dietary recall data with an antioxidant vitamin database for common Korean foods. We analyzed through the multiple logistic regression method to assess the association between dietary antioxidant vitamins and metabolic syndrome.
Results : Men in the highest tertile of vitamin C (OR=0.75, 95% CI=0.58-0.95, p for trend=0.0212) and vitamin E (OR=0.76, 95% CI=0.60-0.96, p for trend=0.0212) intakes showed a significantly lower prevalence of metabolic syndrome than those in the lowest tertiles. Women in the highest intake group of vitamin A had a lower OR for increased waist circumference (OR=0.80, 95% CI=0.66-0.99, p for trend=0.0618) than the lowest intake group. The OR for elevated triglycerides was lower among women in the highest tertile of vitamin C compared with those in the lowest tertile (OR=0.75, 95% CI=0.61-0.93, p for trend=0.0016).
Conclusions : These results suggest that the dietary intake of antioxidant vitamins might be associated with the prevalence of metabolic syndrome among Korean adults. Further prospective research is required to elucidate the association between dietary antioxidants intake and the incidence of metabolic syndrome and other chronic diseases.
