First Lady Michelle Obama hailed a new government report that shows a slight decline in obesity among low-income preschoolers, which she regards as a vindication of her efforts to fight childhood obesity.

“Today’s announcement reaffirms my belief that together, we are making a real difference in helping kids across the country get a healthier start to life,” Mrs. Obama said in a statement.  “We know how essential it is to set our youngest children on a path towards a lifetime of healthy eating and physical activity, and more than 10,000 childcare programs participating in the Let’s Move! Child Care initiative are doing vitally important work on this front. Yet, while this announcement reflects important progress, we also know that there is tremendous work still to be done to support healthy futures for all our children.”

The preschool obesity rate decline slightly in 19 states, according to the CDC, including a drop of at least one point in Florida, Georgia, Missouri, New Jersey, South Dakota, and the U.S. Virgin Islands.

“While the changes are small, for the first time in a generation they are going in the right direction,” CDC director Tom Frieden said.

The CDC said that kids need to eat healthier food and get more physical activity, two lifestyle choices Mrs. Obama has emphasized since coming to the White House.
