Micronutrient intake and the presence of the metabolic syndrome.

ABSTRACT

BACKGROUND: Dietary micronutrients have been proposed to protect against oxidative damage and related clinical complications. AIMS: We aimed to compare the micronutrient intake between individuals with and without metabolic syndrome (MS). MATERIALS AND METHODS: This cross-sectional study included 3800 men and women who were aged between 35 and 65 years. The diagnosis of the MS was based on International Diabetes Federation criteria. Dietary intake of participants was assessed using a questionnaire for 24 h dietary recall. Student's t-test and Mann-Whitney U-tests were used for comparing the micronutrient intake of subjects with or without the MS and the odds ratio for the presence of the MS was calculated for each micronutrient by control for total energy intake adjusted by the residue method. RESULTS: The mean age of MS subjects and the control group was 48.8 ± 7.9 years and 47.6 ± 7.6 years, respectively. Energy-adjusted intake of vitamin E (P < 0.05), B2 (P < 0.01), and B12 (P < 0.05) was higher in normal women compared with women with MS. Energy-adjusted intake of vitamin B1 was significantly higher in women with MS. After logistic regression analysis, no significant association between micronutrient intake and MS was shown. CONCLUSION: We found no significant association between micronutrient intake and MS.
