Snoring may serve as a wake-up call for pregnant women who are likely to develop hypertension and deliver infants with low birth weights. Because snoring is common during pregnancy, investigators in Sweden set out to determine if it affects the health of pregnant women. Researchers at Umea University Hospital studied more than 500 pregnant women, and they analyzed birth weight and Apgar scores of their infants.

Last month in Chest, the researchers reported that 24% of the women said snoring started or worsened by their third trimester; 23% said they snored every night or almost nightly in the last week before delivery. Of habitual snorers, 11% had sleep apnea, compared with 2% who snored less often.
