Two hundred and thirty-eight pregnant women were enrolled. All subjects answered the Berlin questionnaire; this include information on age, weight, height, gravid health status, gestational age, witnessed incidences of snoring, and symptoms associated with sleep apnea. The description of snoring as frequency, volume, complaints from other people and bouts of sleep apnea were recorded and analyzed.

  The prevalence of snoring in pregnancy was 35.29%. The snoring volume, recorded as slightly louder than breathing, in this group was 91.67%. One-fourth of the cases presented with snoring approximately 3-4 times a week with complaints of snoring bothering other people. The incidence of sleep apnea was found in 5.95% of this group.
