  1. WFS indicates WIC Fresh Start, EHE online existing health education, FM farmers’ market, FV fruit and vegetable(s), LGSI locally grown, seasonal items. Least square means and standard errors were derived from linear mixed effects models that controlled for baseline measures of each outcome and pregnancy status, breastfeeding status, receiving assistance other than WIC, and social desirability trait. WFS and EHE means highlighted in bold differ significantly from one another
