- Sleep position during the last 2 weeks of pregnancy may affect risk for stillbirths.
- Encourage side-sleeping to reduce the risk for stillbirth.
Why this matters
- It may be safer for pregnant women to sleep on their sides after 28 weeks.
- Sleeping in the supine position causes inferior vena cava and aortic compression by the pregnant uterus, which reduces maternal-fetal blood flow and has the potential to compromise fetal well-being.
- More late stillbirths associated with supine going-to-sleep position compared with left side going-to-sleep position (aOR, 2.63; P<.0001>
- Nulliparity (aOR, 1.70; P<.0001 parity p=".001)," elevated bmi south asian ethnicity smoking beyond the first trimester and for gestational age percentile were all associated with increased risk stillbirth.>
- Systematic search and meta-analysis (5 case-control studies with individual-level data, 2257 participants).
- Primary outcome: late stillbirth.
