A lack of sleep and reduced physical activity during pregnancy are linked to risk of preterm birth, according to new research led by the Stanford School of Medicine.

In the study, which published online Sept. 28 in npj Digital Medicine, the researchers collected data from devices worn by more than 1,000 women throughout pregnancy. With a machine learning algorithm, the scientists sifted through participants’ activity information to detect fine-grained changes in sleep and physical activity patterns.
