Obesity Rates Decline Among U.S. Preschoolers

Obesity and extreme obesity rates among low-income U.S. preschoolers went down for the first time in recent years, according to a new study published in the Journal of the American Medical Association (JAMA). The findings suggest nutrition and anti-obesity initiatives are making headway.

Researchers at the Centers for Disease Control and Prevention (CDC) used data from the Pediatric Nutrition Surveillance System that includes almost 50% of children eligible for federally funded maternal and child health and nutrition programs. The study included 27.5 million children aged 2 to 4 years in 30 states and the District of Columbia.

From 2003 through 2010, the prevalence of obesity decreased slightly from 15.21% to 14.94%. Similarly, the prevalence of extreme obesity decreased from 2.22% to 2.07%. However, from 1998 through 2003, the prevalence of obesity increased from 13.05% to 15.21%, and the prevalence of extreme obesity increased from 1.75% to 2.22%.

From 2003 through 2010, the prevalence of extreme obesity decreased among all racial groups except American Indians/Alaska Natives. The greatest decrease was among 2-year-old and Asian/Pacific Islander children.
