After decades of steady increases, 19 states and U.S. territories saw small decreases in their rates of obesity among low-income preschoolers. And another 20 states held steady at current rates.

A CDC map shows several Southern states — including Florida, Georgia and Mississippi — that are part of the downward trend.
