  1. aModels were adjusted for variables found to be significantly associated with the completion of any home visit and included maternal age, pre-pregnancy BMI, and marital status. Each model after birth was also adjusted for breastfeeding, e.g. the 3-month model included a variable for continued breastfeeding at 3 months, the 6-month model included a variable for continued breastfeeding at 6 months, etc. bWeight-for-age Z-score. cWeight-for-length Z-score
