Japan, seeking trim waists, measures millions

But because the new state-prescribed limit for male waistlines is a strict 33.5 inches, he had anxiously measured himself at home a couple of days earlier. “I’m on the border,” he said.

Under a national law that came into effect two months ago, companies and local governments must now measure the waistlines of Japanese people between the ages of 40 and 74 as part of their annual checkups. That represents more than 56 million waistlines, or about 44 percent of the entire population.

Those exceeding government limits— 33.5 inches for men and 35.4 inches for women, which are identical to thresholds established in 2005 for Japan by the International Diabetes Federation as an easy guideline for identifying health risk— and having a weight-related ailment will be given dieting guidance if after three months they do not lose weight. If necessary, those people will be steered toward further re-education after six more months.

To reach its goals of shrinking the overweight population by 10 per cent over the next four years and 25 per cent over the next seven years, the government will impose financial penalties on companies and local governments that fail to meet specific targets. The country’s Ministry of Health argues that the campaign will keep the spread of diseases like diabetes and strokes in check.

The ministry also says that curbing widening waistlines will rein in a rapidly aging society’s ballooning health care costs.But critics say that the government guidelines— especially the one about male waistlines— are simply too strict and that more than half of all men will be considered overweight.

The campaign started a couple of years ago when the Health Ministry began beating the drums for a medical condition that few Japanese had ever hearing of metabolic syndrome — a collection of factors that heighten the risk of developing vascular disease and diabetes. Those include abdominal obesity, high blood pressure and high levels of blood glucose and cholesterol. In no time, the scary-sounding condition was popularly shortened to the funny-sounding metabo, and it has become the nation’s shorthand for overweight.
