MedicalResearch.com Interview with: [caption id="attachment_48781" align="alignleft" width="200"] Dr. Chaparro[/caption] M. Pia Chaparro, MS, PhD Assistant Professor Department of Global Community Health and Behavioral Sciences School of Public Health and Tropical Medicine Tulane University New Orleans, LA 70112 MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2009, the WIC program changed the food packages participants receive to better align them with federal dietary guidelines. These changes included the addition of fruits, vegetables, and whole grains; a reduction in the amount of dairy and juice; and a calibration in formula amounts to match infants’ age and needs. We found that this change in the food package was associated with a 10-12% lower obesity risk at age 4 years among children who participated in WIC in Los Angeles County continuously from birth until age 4.
