(AP) -- People who sleep fewer than six hours a night - or more than nine - are more likely to be obese, according to a new government study that is one of the largest to show a link between irregular sleep and big bellies. The study also linked light sleepers to higher smoking rates, less physical activity and more alcohol use.
