  1. WFS indicates WIC Fresh Start, EHE online existing health education, FM farmers’ market, FV fruit and vegetable(s). Odds ratios and confidence intervals were derived from generalized 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. Odds ratios and confidence intervals indicate the likelihood of the outcome among those completing the WFS lesson as compared to an EHE lesson. Values highlighted in bold indicate a significant difference by lesson. P values are for tests of the equality of odds ratios.
