Childhood Obesity Trends Over Time in 2-5 Year-Old U.S. Children. Prevalence of obesity, defined as a BMI ≥95th percentile in 2- to 5-year-olds children included in NHANES, and in 2- to 4-year-olds included in PedNSS. The PedNSS data were drawn from data reported in MMWR 2009;58:76, and represent the annual average prevalence among children in the following states: California, Florida, Georgia, Idaho, Iowa, Kansas, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, New Hampshire, New Jersey, New Mexico, New York, South Dakota, and Washington. Mississippi did not report data for 2003 and therefore was not included in that year’s calculation.
States (in gray) and municipalities that have reported decreases in the prevalence of childhood obesity. In contrast to the NHANES and PedNSS data shown in Fig 1, the ages of the subjects of these reports are variable, but the observed decreases support the findings in younger children.
