Obesity affects 17 percent of children and adolescents and almost 36 percent of adults in the United States. In 2014, the IOM created the Roundtable on Obesity Solutions to engage leadership from multiple sectors in responding to the obesity crisis. In the roundtable’s second workshop, which was held on September 30, 2014, presenters explored ways in which sectors can work together to achieve more progress than would be possible with any sector working on its own.
