For as long as 16 years of follow-up investigation, the results published by the American Heart Association's "circle" magazine website. The study concluded that, waist circumference, the largest female - 88.9 centimeters and above, compared to less than 71.12 centimeters in waist circumference of women, the risk of premature death increased by 79%. This risk assessment has consolidated a variety of health factors.

The studyReport said, with a small waist compared to women, even if normal weight, waist circumference, the largest women die fromThe risk of cardiovascular disease, or up to twice the risk of dying of cancer 63% higher.

Not involved in the study of the University of Southern CaliforniaObesity researcher Richard N · Bergman said that with the bellies, taking into account the severity of the disease, these findings are not surprising.
