Relationships between Objectively Measured Sedentary Behavior during Pregnancy and Infant Birthweight.

Background: Although numerous studies have assessed physical activity during pregnancy and relationships with infant outcomes, such as birthweight, few have evaluated sedentary behavior. Our objective was to evaluate sedentary behavior across pregnancy and relationships with infant birthweight in a sociodemographically diverse sample.

Methods: We measured device-assessed sedentary behavior and physical activity over three days at 16-18, 24-26, and 32-34 weeks gestation and infant birthweight from medical records among 71 participants.
