In conducting the study, researchers analyzed health data of 6,000 middle-aged men over a 15-year period and found that when correcting for other health factors, obesity still raised chances of death by up to 75 percent.
Researchers came up with that figure by controlling for age and smoking factors. When they factored in hypertension, high cholesterol and medication, they found that obesity increased chances of death from coronary heart disease by 60 percent.
Authors of the study noted that when research began 20 years ago, obesity was much less prevalent than it is today. As such, they said the study group was relatively small and that further testing is needed.
"The obesity generation is coming of age. We are going to see more and more complications from obesity, and coming at an earlier age," said Jennifer Logue, Ph.D., lead author and clinical lecturer in biochemistry and metabolic medicine at the University of Glasgow.
