Abstract
Objective: The Ministry of Health, Labour and Welfare (MHLW) has introduced a specific health examination for metabolic syndrome (MS) using modified criteria of the Japanese Committee for the Diagnostic Criteria of Metabolic Syndrome (JCDMS). Examinees who satisfy the mandatory condition of obesity and are positive for at least 1 MHLW criterion may receive specific health guidance, but examinees who are on medication (EOnM) for hypertension, dyslipidemia, or diabetes may not because they are under the guidance of clinicians. We analyzed the medical check-up results for EOnM to see if their data were better than examinees with no medication (ENoM).
Methods: Our subjects were 6,642 men between 40 and 64 years old. Diagnosis was conducted for EOnM assuming that they were not on medication.
Results: EOnM had a significantly higher incidence of enlarged waist circumference and higher body mass index than ENoM. Also, the incidence of elevated fasting plasma glucose among EOnM for hypertension and/or dyslipidemia, and that of lipid abnormality among EOnM for diabetes and/or hypertension, was significantly higher in most cases than ENoM. EOnM for dyslipidemia and diabetes had a significantly higher incidence of elevated blood pressure than ENoM. When blood pressure was excluded in making a diagnosis for examinees taking only antihypertensives and ENoM, in the former, the incidence of those who should receive specific health guidance and that of those positive for at least one of the JCDMS criteria was significantly higher than in the latter. This was also the case with examinees taking only medicine for dyslipidemia.
Conclusions: The medical check-up results for examinees on medication were no better than those without medication.
