Percent of WIC participants ages 2-4 with obesity
The WIC Participant and Program Characteristics (WICPPC) survey gathers data from all states on all participants. A strength of these data is that they are a census of all WIC participants and not just a sample of them. The data include height and weight measurements for children, which are collected by medical staff during certification visits, and then are used to calculate BMI and obesity rates among children ages 2 to 4. The data are gathered in April of even-numbered years, and analyzed by the CDC.
