Women who snore loudly in late pregnancy have an increased risk of depression and needing a caesarean, New Zealand research has revealed.
The Massey University study backed up international research and found snoring could also be attributed to a low birth weight.
One in five Kiwi women are loud snorers in the final months of pregnancy, the study found.
It also revealed nearly a third of pregnant women sleep fewer than six hours a night in the late stages.
The study, led by Dr Leigh Signal and Dr Sarah-Jane Paine, involved more than 1000 women aged 16 to 46.
