问题     If you’re one of those people who tends to put on weight around your middle, what doctors call an "apple shape"—what the rest of us call a beer belly—you’ve probably been told that you’re at higher risk of heart disease. But one large new review study suggests you shouldn’t be too【C1】______after all.
    It turns out that the apple-shaped among us are not at any higher risk of heart trouble as people with pear shapes or any other kind of fat【C2】______In the latest study, researchers at the Emerging Risk Factors Collaboration in the UK reviewed records of more than 220 000 participants in 58 different trials that followed【C3】______for more than 10 years for heart-related events.

    In fact, the researchers write in the journal Lancet, various measures of obesity,【C4】______body mass index(or BMI, a combined measure of height and weight), waist circumference and waist-to-hip ratio, all had about the same predictive value in identifying increased risk of a heart attack. What’s more,【C5】______to the forecasting power of known risk factors such as high cholesterol, high blood pressure and a history of diabetes(糖尿病), the obesity measures added very little to the【C6】______ of risk assessment.
    Previous studies had focused not just on overweight, but on the type and【C7】______ of fat deposits as a red flag for heart disease. The thinking was that even without blood tests for cholesterol or blood pressure, body shape alone could alert doctors and patients to the fact that patients might be at higher risk of heart problems. One headline-grabbing survey reported a three-fold【C8】______risk in heart disease among those with abdominal fat—folks with apple-shaped bodies -and speculated that visceral(内脏的)fat, which tends to【C9】______around the middle, is particularly hazardous for the heart, since it nestles deep within organs and can pump out hormones that【C10】______insulin(胰岛素)
