In conclusion, this study confirmed increased snoring and showed narrower upper airways during the third trimester of pregnancy. Pregnant females had smaller mean pharyngeal areas compared with post-partum in the seated (mean difference 0.18 95% CI 0.02–0.32), supine (mean difference 0.20 95% CI 0.06–0.35) and lateral postures (mean difference 0.26 95% CI 0.12–0.39). ![]() Pregnant females had significantly smaller upper airways than nonpregnant females at the oropharyngeal junction when seated (mean difference 0.12 95% CI 0.008–0.25), and smaller mean pharyngeal areas in the seated (mean difference 0.14 95% CI 0.001–0.28), supine (mean difference 0.11 95% CI 0.01–0.22) and lateral postures (mean difference 0.13 95% CI 0.02–0.24) compared with the nonpregnant females. Snoring was less common in nonpregnant (17%) than pregnant females (41% odds ratio (OR) 3.34 95% confidence interval (CI) 1.65–6.74) and returned to nonpregnant levels after delivery (18% OR 0.15 95% CI 0.06–0.40). ![]() Upper airway dimensions were measured using acoustic reflection. One-hundred nonpregnant females were also recruited. ![]() One-hundred females in the third trimester of pregnancy were recruited and 50 agreed to be restudied 3 months after delivery. ![]() The aim of this study was to determine whether pregnancy was associated with upper airway narrowing. Sleep-disordered breathing and snoring are common in pregnancy. ![]()
