“Nationally representative data do not show any significant changes in obesity prevalence in the most recently available years … unfortunately, there is an upward trend of more severe forms of obesity, and further investigations into the causes of and solutions to this problem are needed,” Skinner and co-author Joseph Skelton, MD, of Wake Forest University in Winston-Salem, N.C., said.
