There doesn't appear to be much headway being made in the battle to curb obesity in the United States, according to a pair of studies released Tuesday. Updated findings show that 35% of men, 40% of women and 17% of children and adolescents are obese, according to two articles published in the Journal of the American Medical Association. These figures remain high in spite of the "hundreds of millions of dollars" that have been pumped into research, trials, observational studies, community and hospital programs, and the development of devices and drugs. One study looked specifically at trends among adults from 2005 to 2014. The results, based on data from more than 2,600 men and 2,800 women, showed that for women, the prevalence of obesity went up, while the prevalence among men remained the same.
