BACKGROUND: Snoring is common in pregnancy, but there are only a few studies that have investigated the relationship of snoring and pregnancy complications. We aimed to investigate the relationship of snoring and witnessed sleep apnoeas with pregnancy-induced hypertension. METHODS: A questionnaire was administered on the day of delivery to 456 women at the Department of Obstetrics, Hospital Donación F. Santojanni, Buenos Aires, Argentina. Pregnancy complications and blood pressure measurements were recorded from each woman's medical chart. RESULTS: Some 156 (35%) of 447 women with singleton pregnancies who answered the questionnaire, snored at some time during their pregnancy. Snoring was related to pregnancy-induced hypertension and pre-eclampsia combined, with an adjusted odds ratio of 1.82 (95% CI: 1.16-2.84; p <0.01), independent of body mass index before pregnancy, weight gain during pregnancy, neck circumference, smoking, alcohol and age. Witnessed sleep apnoeas were also related to pregnancy-induced hypertensive disease, with an adjusted odds ratio of 8.00 (95% CI: 2.71-23.55; p <0.001). Daytime sleepiness was more prevalent in snoring women. CONCLUSIONS: Snoring and witnessed sleep apnoeas are independently related to pregnancy-induced hypertensive disease.
