Women in standard care attended their regularly scheduled
visits with their prenatal care providers, which typically occurred
monthly until 28 wk gestation, biweekly for 28–36 wk gestation,
weekly until delivery, and at 6 wk postpartum. Women received
standard nutrition counseling provided by physicians, nurses,
nutritionists, and counselors from the Women, Infants, and
Children’s state program. Women were weighed by nurses at
each clinical visit; weight graphs were not provided. In addition,
women attended a brief (15 min) face-to-face visit at study entry
with the study interventionist and received study newsletters at
2-mo intervals during pregnancy and postpartum that provided
general information about pregnancy-related issues (eg, prenatal
vitamins and maternity clothes); these contacts were designed to
improve retention in the study.
