Twin pregnancy and the effects of prophylactic leave of absence on pregnancy duration and birth weight.

The purpose of the study was to evaluate the effects of taking prophylactic leave of absence from work during a twin pregnancy. Pregnancy outcome for 78 women who were prescribed prophylactic leave of absence from work to prevent preterm delivery was compared with a group of 78 twin-pregnant controls who did not take prophylactic leave. Gestational duration and birth weight did not differ between the two groups. The results indicate that prophylactic leave of absence from work did not improve the outcome of a twin pregnancy.
