This project involved the execution of data sharing agreements and preparation of a publically accessible database and summary reports for the National Food and Nutrition Study (NATFAN). NATFAN used repeated cross-sectional surveys conducted in WIC clinics between 2009 and 2011, before and after the changes in the WIC food benefit, to examine dietary practices. Women who attended WIC clinics during the periods of the two surveys completed questionnaires about their own (Women questionnaire), their child’s (Child questionnaire), or their infant’s (Infant questionnaire) consumption of certain foods related to the changes in the WIC food package. Reports on food consumption for milk, grains, fruits and vegetables, beverages, and baby foods include data from the 39 State WIC Programs and consolidated data from 10 Indian Tribal Organization WIC Programs before and after the WIC changes. The data dictionary and code book and the public dataset include data from all participating WIC programs.
