In the wake of a report last week showing a very small decline in obesity among low-income preschoolers, former President Bill Clinton is trotting out the debunked claim that Michelle Obama’s Let’s Move! initiative deserves some of the credit.

The timeframe of the study cited by Clinton is 2008 to 2011. At least half of that time period occurred before the Let’s Move! program could have had any effect. The program wasn’t even announced, let alone implemented, until February 9, 2010.

According to a research brief published in the Journal of the American Medical Association, the rate of obesity among low-income preschoolers has been declining since 2003 — six years before the Obamas entered the White House.
