Researchers interviewed “155 women who delivered a stillborn baby at least 28 weeks’ gestation” and compared them with “310 pregnant women with typical ongoing pregnancies.”
The women were asked about their “sleep position during the last month of their pregnancy, the last week of their pregnancy, and on the night they believed the stillbirth occurred.”
Women who slept on their “back or on their right side on the night before a stillbirth were twice as likely to have a late stillbirth,” compared with women who slept on their left side.
MedPage Today reported that the researchers noted that women whose offspring were stillborn “typically were heavier, of lower socioeconomic status, and smokers.”
Meanwhile, an editorial accompanying the study “advised caution in interpreting these findings. ‘A forceful campaign urging pregnant women to sleep on their left side is not yet warranted,’” the editorialists wrote.
Nevertheless, I see no harm in letting women know of this study and I’ll be recommending women who are pregnant sleep on their left side … until other data are available.
