Gestational age must be greater than 37 weeks and less than 41 weeks, as ascertained by certain last menstrual period and/or first trimester ultrasound. The chart must include a diagnosis of active labor or spontaneous rupture of membranes, and the patient must have had at least two third-trimester prenatal checkups at OSU Houston Center OB/GYN, including one during the last two weeks of gestation. We will define a term infant as 37 weeks gestation or greater (3). Our study population will consist of mainly Medicaid patients. The ethnic blend of our study population will include Caucasian, African-American, Hispanic, American Indian, and Asian women.

Exclusion
- We will exclude women with multiple gestation, because they are at risk of preterm labor. We will also exclude anyone else who had preterm delivery. In addition, we will exclude women with a diagnosis of liver disease, including intrahepatic cholestasis and hepatitis, chronic hypertension, intraamniotic infection, preeclampsia or its variant, HELLP syndrome, cholelithiasis, inadequate prenatal care, preterm labor, or induction of labor (other than due to premature rupture of membranes).
