Infant Temperament and Early Infant Growth and Child Overweight in GDM Offspring

The NIH-funded Study of Women, Infant Feeding and Type 2 Diabetes (SWIFT) is a prospective cohort study of 1,035 postpartum women with a recent pregnancy complicated by gestational diabetes who were recruited from 2008 to 2011, and attended three in-person visits in two years that included annual screening for Type 2 diabetes. An ancillary study to SWIFT, the SWIFT Offspring Study, enrolled 480 mother-infant pairs and conducted assessments of infant feeding and behaviors, and measured growth at 2 months, 6 months and 12 months among offspring exposed to maternal gestational diabetes in utero. In this project, a secondary data analysis will assess associations between infant temperament and growth during the first year of life in SWIFT Offspring, and the association with subsequent risk of overweight and obesity at ages 2 to 5 years. Prenatal risk factors, infant breastfeeding, and other early feeding practices will be evaluated as confounders and/or effect modifiers.
