URBANA, Ill. - Over the past 30 years, the prevalence of overweight and obesity has doubled in 2- to 5-year-olds and tripled in children aged 6 to 11 years. To address this public health concern, in 2011, the USDA funded the Illinois Transdisciplinary Obesity Prevention Program (I-TOPP), a joint doctoral/Masters of Public Health (MPH) degree program, at the University of Illinois with the goal of training future leaders to address the problem of childhood obesity.
