Abstract

Activity restriction has traditionally been recommended to pregnant women, especially high-risk patients, to reduce preterm birth. However, there is no scientific evidence that bed-rest reduces preterm birth and, in many studies, women on bed-rest had higher rates of delivering preterm. Bed-rest in pregnancy is associated with significant physiological and psychosocial sequelae and reduced neonatal birth weight and be cannot be endorsed, even in women with a short cervix. The practice of prescribing bed-rest in pregnancy is outdated and should be abandoned.
