THURSDAY, Feb. 10 (HealthDay News) -- In a study that included data on nearly 73,000 Norwegian women, researchers found that taking folate during pregnancy didn’t appear to reduce the rate of premature births. "[Our] data do not support a protective effect of folate on spontaneous preterm delivery frequency, but folate does not seem to have an adverse effect on pregnancy either,” said study author Dr. Verena Sengpiel, from the department of obstetrics and gynecology at Sahlgrenska University Hospital in Goteborg, Sweden.
