All 456 subjects were referred to the Sleep Center for PSG. If admitted to antepartum during gestation, a T3D was performed. 398 subjects did not complete PSG or T3D. 58 subjects completed PSG and/or T3D. Of the 58 subjects who completed sleep testing via PSG or T3D, 15.5% were diagnosed with obstructive sleep apnea.
