Obesity more deadly for men than women: Study

Obesity is nearly three times more deadly for men than it is for women, new research suggests. In a study of nearly 4 million men and women around the globe, the risk of dying before the age of 70 was 19 percent for men and 11 percent for women of normal weight.  But that risk jumped to 30 percent and 15 percent, respectively, for obese men and women. That's an absolute increased risk of 11 percent for men and 4 percent for women, the researchers reported.
"Obesity is second only to smoking as a cause of premature death in America," said lead researcher Richard Peto, professor of medical statistics and epidemiology at the University of Oxford in England.
"If you could lose about 10 percent of your weight, a woman would knock 10 percent off the risk of dying before she was 70, and for a man it would knock about 20 percent off," Peto said. Why obese men are at greater risk for premature death than women isn't clear.
"Our study was not able to address this question, but previous observations have suggested that obese men have greater insulin resistance, liver fat levels and diabetes risk than women," said study co-author Dr. Emanuele Di Angelantonio, a lecturer at the University of Cambridge in England.
The study was published online July 13 in The Lancet.
One U.S. expert said more research is needed to explore the apparent link between obesity and mortality. "We still have more work to do to better understand how weight, weight gain, and weight loss influence mortality," said Barry Graubard, a senior investigator in the biostatistics branch of the U.S. National Cancer Institute. He co-authored an accompanying journal editorial.
