Previous research argued that being overweight and 'apple shaped' greatly increased the risk of heart disease.
This method uses the "waist-to-hip" ratio and compares the distance around the hips and waist to measure what is known as central obesity.
It can tell if someone is "apple shaped - with a bulging middle - or "pear shaped", with a narrower waist and fatter hips and bottom.
Others have suggested concentrating on a measurement of the waist alone.
But this new study, which looked at 220,000 people over almost 10 years, found that all three measures indicated risk of heart attack or stroke.
The study was led by Professor John Danesh from Cambridge University and concluded that none of the measures on their own improved the prediction of heart disease, especially when doctors could also assess other warning signs like blood pressure and cholesterol levels.
Writing in the Lancet, Professor Danesh said: "Whether assessed singly or in combination, body-mass index, waist circumference, and waist-to-hip ratio do not improve prediction of first-onset cardiovascular disease when additional information exists on blood pressure, history of diabetes, and cholesterol measures."
The study was funded by the Medical Research Council (MRC) and the British Heart Foundation (BHF).
