SWIFT Study Participants
The SWIFT Study enrolled 1,033 women with gestational diabetes and followed up 1,010 women who did not have diabetes at the study baseline visit (6 to 9 weeks after delivery). Over 23 percent of SWIFT women have developed type 2 diabetes during follow up through 2020.
The SWIFT Study has broad racial and ethnic diversity, consisting of 31% Hispanic, 35% Asian and Pacific Islanders, 8% Black, 24% White and 2% other groups.
Original Research Methods
The SWIFT Study collected medical information, oral glucose tolerance tests, body measurements, and surveys in women with recent gestational diabetes. The methods involved annual research exams, phone calls, monthly mailings to assess breastfeeding and infant diet, and electronic health records from early post-delivery starting at 6-9 weeks postpartum and up through 2 years and beyond. The study data included socio-demographics, lifestyle behaviors, sleep, pregnancy and medical history, and breastfeeding intention, intensity and duration, amount of infant formula, detailed feeding habits during the first year of life and child growth measures from birth.
