SAN DIEGO -- Obesity appears to significantly increase the risk of death tied to sleeping pills, nearly doubling the rate of mortality even among those prescribed 18 or fewer pills in a year, researchers reported Friday.
"Obesity emerged as a marker of increased vulnerability," said Robert Langer, M.D., M.P.H., at the annual American Heart Association's Epidemiology and Prevention | Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions in San Diego.
