Some mothers who breastfed supplemented with formula (partial breastfeeding) and some did not (exclusive breastfeeding). To reduce the risk of spurious relations, we limited the food categories examined for differences to foods provided by WIC (e.g., baby-food fruits, vegetables) and a small number of other foods of interest (e.g., we examine consumption of all fruits to gain more insight into the role of baby-food fruits). We did, however, identify food categories for children >6 mo (the age at which WIC begins providing foods other than infant formula) with large differences in the percentage consuming between WIC and non-WIC groups and where the 95% CI for the OR does not contain the null value of 1. Differences between higher- and lower-income nonparticipants were not assessed.

Because this is an exploratory analysis (i.e., we did not start with a specific hypothesis) to assess whether consumption patterns differed between WIC and non-WIC groups, we do not present results of formal hypothesis tests (i.e., P values). The descriptive findings reflect the unadjusted prevalence of infant feeding patterns and consumption of foods by WIC and non-WIC infants and children. These data were further stratified by age range into younger infants (0–5.9 mo), older infants (6–11.9 mo), and young children (12–47.9 mo). Food consumption patterns, specifically the percentage of children in each WIC status group that consumed food from each food group, were derived from the 24-h dietary recall data.
