The researchers measured waist size, waist-to-hip ratio, waist-to-height ratio, and B.M.I., or body mass index, a weight-to-height ratio. All four measures were associated with heart disease, but waist circumference alone predicted heart disease risk regardless of other measures. B.M.I. was a significant predictor in women only if they had a large waist size. The study appeared online April 7 in the journal Circulation: Heart Failure.
The researchers found that a four-inch increase in waist size was associated with about a 15 percent increase in risk for heart disease, both in people of normal weight with a B.M.I. of 25 and in the obese with a B.M.I. above 30.
