Objective: We elucidated the present situation of metabolic syndrome (MetS) and compared clinical characteristics between MetS individuals and those who had a normal abdominal circumference but fulfilled other criteria for diagnosis of MetS (masked MetS).
Methods: 21,668 examinees (men 13,126, women 8,542) were enrolled in this study.
Results: MetS was found in 19% of the men, and in 3% of the women, and its frequency increased with age. In masked MetS, abnormality in systolic and diastolic blood pressure was the most frequently observed criterion for MetS in the laboratory data of both men and women. In a comparison of mean values of laboratory data between MetS and masked MetS, in men, LDL-C, triglyceride, AST, ALT, γ-GTP and HbA1c were significantly higher in MetS, whereas systolic and diastolic blood pressure and HDL-C were significantly higher in masked MetS. As for women, γ-GTP in MetS and HDL-C in masked MetS were significantly higher. Smoking habit was more common in masked MetS, in men. Drinkers were significantly in the majority in masked MetS, in men, while non-drinkers were significantly in the majority in MetS, in women. There was no difference in past medical history between MetS and masked MetS, both in men and women.
Conclusion: Our findings suggested that we should continue existing guidance for those with MetS. For those with masked MetS, in addition to guidance on MetS, that on smoking and drinking should also be given, in consideration of individual diathesis.
