Researchers have found that some methods for trying to stop preterm labor are not as effective as once thought. These include:
- Home uterine monitors1
- Routine screening of all asymptomatic women for bacterial vaginosis (Trichomonas vaginalis) infection.2 Routine screening and treatment with antibiotics did not reduce preterm birth; in fact, the latter increased the risk of preterm birth.2
