Supine sleep in late pregnancy may promote low birth weight

Publish date:: October 3, 2019

Key clinical point: Sleeping in a supine position during the last trimester of pregnancy was significantly associated with lower infant birth weight.

Major finding: Infants born to women who regularly slept supine at 28 weeks’ gestation or later had significantly lower birth weight than did those whose mothers slept on one side (3,410 g vs. 3,554 g).

Study details: The data come from a subgroup analysis of control participants in the Collaborative Individual Participant Data Meta-analysis of Sleep and Stillbirth conducted in Australia, New Zealand, and the United Kingdom.

Disclosures: The study was supported by a Trans-Tasman Research Funding Grant by Cure Kids and Red Nose Australia. Six coauthors reported receiving numerous grants from a variety of organizations. Dr. Anderson and the remaining coauthors had no financial conflicts to disclose.
