Obesity, which affects more than one-third of Americans, is a chronic disease that can shorten one’s life span, but new findings show that its effect on mortality has reduced in recent years among many groups, particularly women. “One of the possibilities our findings suggest, but do not prove, is that advances in medicine, screening procedures and interventions may have reduced the excess mortality associated with Grade 1 obesity; there are yet other explanations, as well,” said one researcher.
