[309-POS]: Snoring during pregnancy: Questionnaire results versus objective measurement (AHI).

OBJECTIVES: Snoring is common during pregnancy, particularly in the last trimester. Most investigators of snoring during pregnancy had utilized questionnaires to determine the presence and severity of snoring. The aim of this study was to determine the efficacy of questionnaires to determine the presence of snoring in pregnant women compared with objectively measured snoring.

METHODS: Berlin questionnaires were administered to 202 pregnant women. One question asked "Do you snore?" Snoring was then recorded in the woman's home using a SonoMat™ device, a thin mattress in which sensors measure and record sound and movement. Apnea hypopnea index (AHI) was determined. The results from the questionnaire were compared to recorded snoring and AHI results.

RESULTS: 124 women answered "Yes" to the question "Do you snore?" and 78 women answered "No" and "I don't know" for score purpose were included in "No". The average gestation was 28 ± 7 weeks. Women who reported "No" were just as likely to report >20% snoring as those who reported "Yes" (35.5%, p=ns).

CONCLUSIONS: This study has demonstrated that questionnaire results are not always a reliable method of determining whether snoring is present, and overnight monitoring should be used to rule out sleep disordered breathing. .
