★What is it?
Metabolic syndrome is a combination of medical disorders that increase the risk of developing heart disease and diabetes. In general, a person with metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as someone without metabolic syndrome.
★Metabolic syndrome is defined by the International Diabetes Federation as:
Central Obesity (*see below) – plus any two of the following:
- - raised triglycerides** (over 150 mg/dl),
- - reduced HDL-cholesterol (less than 40 mg/dl in men & less than 50 mg/dl in women)
- - a raised blood pressure (systolic BP is 130 or higher, or diastolic BP is 85 or higher)
- - a raised fasting blood sugar level (over 100 mg/dl)
** triglycerides are the main constituent of vegetable oil and animal fats.
- Central Obesity
The International Diabetes Federation (IDF) definition of central obesity takes into account waist circumference with ethnicity and gender specific values.
For people of European, Sub-Saharan, and Middle Eastern origin – a waist circumference of 94cm or more for males, or 80cm or more for females indicates central obesity. For people of South & East Asian, ethnic South & Central American origin its 90cm or more for males, or 80cm or more for females.
However, if the BMI (body mass index) is greater than 30 central obesity can be assumed.
In Japan the JASSO standard is used and is slightly different from the IDF definition. With the JASSO definition central obesity is defined as having an abdominal circumference (around the navel) of 85cm or more for males, or 90cm or more for females.
Both National Health Insurance (kokumin kenkō hoken) and Work Place Health Insurance (shokuba kenkō hoken) provide health checks.
– If you hold National Health Insurance (国民健康保険) you may be eligible for a low cost “metabolic” health check.
– If you hold Work Place Health Insurance (職場健康保険) the “metabolic” health check is now part of the annual health check.

If you would like to have a more thorough annual physical done, many clinics offer what is called a ningen-dokku 人間ドック (basically meaning human dry-dock). However, the ningen-dokku usually isn’t covered by National Health Insurance and can take from an hour or two, to an overnight visit, depending on the checks you want to take. Many employers also offer additional optional health checks (at an additional cost) for stomach, colon, cervical, and breast cancer.
