New research published in the Journal of the American Heart Association shows that waist-to-hip ratio is a better heart attack predictor than body mass index (BMI), with so-called “apple shape” women at greater risk than their male counterparts. According to the research from the George Institute for Global Health, waist-to-hip ratio is an 18% better heart attack predictor than BMI in women and 6% in men. However, the research also found that BMI was linked to heart disease risk in both sexes. For the research, the team from the George Institute in Oxford interviewed nearly 500,000 UK adults aged 40 to 69. They found women who had bigger waists relative to their hips are at more risk of heart attacks than men with similar body shapes. Speaking about the findings of the research, Ashleigh Doggett, senior cardiac nurse at the British Heart Foundation, said: "Considering the large amount of UK participants, this is a very interesting study which highlights that obesity remains a risk factor for heart attacks in both men and women. "Interestingly, it suggests that those of us who are 'apple' as opposed to 'pear' shape, especially women, may be at higher risk of a heart attack.” The researchers say their findings suggest the differences in the way men and women store fat may affect their risk of heart disease. While more research is needed, these findings do support the notion that being “apple shape” (having proportionally more fat around the abdomen) is more hazardous for your health than being “pear shape” (having proportionally more fat stored around the hips. The full findings of the research can be found in the Journal of the American Heart Association.
