Introduction: Cardiometabolic risk factors characteristic of the metabolic syndrome (MS) influence zinc metabolism, either alone or in combination.

Objective: This study aims to compare plasma zinc and zinc intake among the three groups of individuals with MS, distributed according to the number of components of SM.

Methods: Cross-sectional study including 88 individuals with MS, diagnosed according to NCEP-ATP III. The groups were defined, considering three (n = 36), four (n = 40) and five components of MS (n = 12). Zinc intake was evaluated by two 24-hour recall. Blood pressure, waist circumference and fasting glycemia, high density lipoprotein cholesterol and triglycerides were measured. Analysis of plasma zinc was performed by atomic absorption spectrophotometry. We used ANOVA, followed by the Tukey test, for comparisons between the groups.

Results and discussion: The mean age was 5011 years, predominantly female (72%). We found ten different phenotypes based on the three components of MS, with emphasis on the phenotype: arterial hypertension or high blood pressure, diabetes mellitus or fasting blood glucose and increased waist circumference (11.4%). There were no significant differences in plasma zinc between the groups with three, four and five components, presenting a mean of 92.62 (18.26) µg / dL; 86.24 (17.88) µg / dL; 86.94 (17.12) µg / dL, respectively (p> 0.05). The percentages of zinc intake inadequacy were 75%, 73.6% and 66.6% in the groups with three, four and five components, respectively.

Conclusion: Individuals with MS, regardless of the number of components, present mean plasma zinc within normal range and low dietary zinc intake.
