Obesity is a killer
Scientists have suggested that obesity is a killer in its own right, irrespective of other biological or social risk factors traditionally associated with coronary heart disease.
Increasing weight is associated with a higher prevalence of known risk factors for coronary artery disease, such as diabetes, high blood pressure and cholesterol.
And it has been assumed that these have been responsible for the increased risk of heart disease seen in obesity, say the authors.
The researchers from the British Heart Foundation Cardiovascular Research Centre, at the University of Glasgow, tracked the health of more than 6,000 middle-aged men with high cholesterol, but no history of diabetes or cardiovascular disease, for around 15 years.
