sleepiness, ’s Breath
LATE PREGNANCY, SECONDARY, RECRUITMENT
This secondary analysis used data from Baby’s Breath, a tailored video intervention tested in a randomized control trial (NCT00142623), aimed to reduce smoke exposure among pregnant women and their infants. For this study, we used sleepiness ratings collected at three time points: Early pregnancy (12–16 weeks gestation), late pregnancy (32 weeks gestation), and 6 months postpartum, as well as breastfeeding intentions and attitudes collected at both pregnancy time points, breastfeeding initiation upon hospital discharge after delivery, breastfeeding behavior at 3 and 6 months postpartum, and infant feeding practices at 6 months postpartum. Participants, who were recruited from prenatal clinics that largely serve low-income families in the Providence, RI area, were eligible if they spoke English, were at least 18 years of age, smoke-exposed (i.e., currently smoking, recently quit, or exposed to environmental tobacco smoke), experiencing a normal singleton pregnancy, and not more than 16 weeks pregnant at the time of recruitment. Participants also needed to have access to a working telephone and a VCR/DVD player. Details about the intervention can be found in Risica et al. (2017) [
