This study was conducted to estimate antioxidant vitamin intake and total antioxidant capacity (TAC) from diet and dietary supplements and to examine their association with metabolic syndrome (MetS) in Korean adults. Out of 6308 adults 1964 years old from the 20102011 Korea National Health and Nutrition Examination Survey, 1847 adults were classified as dietary supplement users and the other 4461 adults were classified as non-users. Antioxidant intake and TAC from diet and dietary supplements were estimated using dietary intake data and linked with the antioxidant and TAC database for common Korean foods. The prevalence of MetS was lower in dietary supplement users (odds ratio (OR) = 0.82; 95% confidence interval (CI), 0.68-0.98) than that in non-users. Among dietary supplement users, a lower prevalence of MetS was observed in the highest tertile for vitamin A (OR = 0.72; 95% CI, 0.53-0.99) and vitamin E (OR = 0.74; 95% CI, 0.55- 0.99) intake than that in the lowest tertile among non-users. Subjects in the highest tertile of TAC among dietary supplement users showed a lower prevalence of MetS (OR = 0.72; 95% CI, 0.52-0.99) than non-users. The results imply that intake of vitamin A, vitamin E, and TAC from dietary supplements might have a protective effect on MetS among Korean adults.
本研究旨在估计韩国成年人从饮食和膳食补充剂中摄入抗氧化维生素和总抗氧化能力（TAC），并探讨它们与代谢综合征（MetS）的关系。在 2010 年至 2011 年韩国国家健康和营养调查中，从 6308 名 19 至 64 岁的成年人中，1847 名成年人被归类为膳食补充剂使用者，另外 4461 名成年人被归类为非使用者。使用膳食摄入数据估算饮食和膳食补充剂中抗氧化剂的摄入量和 TAC，并将其与常见韩国食物的抗氧化剂和 TAC 数据库相关联。与非使用者相比，膳食补充剂使用者的 MetS 患病率较低（比值比（OR）=0.82；95%置信区间（CI），0.68-0.98）。在膳食补充剂使用者中，与非使用者中最低三分位相比，维生素 A（OR=0.72；95%CI，0.53-0.99）和维生素 E（OR=0.74；95%CI，0.55-0.99）摄入量最高三分位的 MetS 患病率较低。与非使用者相比，膳食补充剂使用者中 TAC 最高三分位的受试者 MetS 患病率较低（OR=0.72；95%CI，0.52-0.99）。结果表明，来自膳食补充剂的维生素 A、维生素 E 和 TAC 的摄入可能对韩国成年人的 MetS 具有保护作用。
