Japan to Study Whether Women with Waist Measurements Above 80cm (31.5 in) are Obese

Japan to Study Whether Women with Waist Measurements Above 80cm (31.5 in) are Obese
女性は腹囲80センチ以上も肥満症に…学会検討

The Japan Society for the Study of Obesity has begun investigating whether women with waist sizes above 80cm (31.5 in) and Body Mass Indices (BMIs) lower than 25 are obese.

Until now people with BMIs lower than 25 have not been considered obese. The study could impact the Ministry of Health, Labor, and Welfare’s standards for diagnosing metabolic syndrome (one of whose symptoms is the collection of fat around the internal organs), one of which is a waist measurement above 85cm (33.5 in) for males or 90cm (35.4 in) for females.

As of now, people with BMIs over 25 and either “other health problems like an abnormal body fat percentage or high blood pressure” or “a waist measurement above above 85cm (33.5 in) for males or 90cm (35.4 in) for females” are diagnosed obese. However, people with sub-25 BMIs and fat collecting around their internal organs have also been indicated as more likely to suffer arteriosclerosis (the hardening of the arteries).

女性は腹囲80センチ以上も肥満症に…学会検討

 日本肥満学会は、体格指数(BMI)25未満で、腹囲80センチ以上の女性についても肥満症の対象とする検討を始めた。

 これまでBMI25未満の人は、肥満症の対象外だった。特定健診のメタボリックシンドローム(内臓脂肪症候群)の腹囲基準(男性85センチ、女性90センチ以上)は、肥満症の診断基準を基本にしているため、厚生労働省が進める特定健診の腹囲基準見直しに影響を与えそうだ。

 現在の基準で肥満症と診断されるのは、BMIが25以上で、かつ「脂質異常や高血圧などの健康障害が見られる」「腹囲が男性85センチ、女性90センチ以上」のどちらかに当てはまった場合。しかし、BMI25未満でも内臓周辺に脂肪がたまると、動脈硬化などが増加する傾向が指摘されている。

    This is interesting from a medical perspective. Probably less pertinent to a country like the US where over 33.9% of the adult population is obese from the good ol’ fashion definition (BMI > 30). In fact, if you use the BMI of 25 as cut-off for overweight, a whopping 68.3% of American adults are overweight or obese. So unfortunately in the US, no one is pushing studies to expand the definition of obesity. Haha. I laugh because otherwise I would cry.

    check it out, the color-graphic of the US is terrifying:
