Early-Mid Pregnancy= 5-21 weeks gestation; Late Pregnancy= 30-34 weeks gestation. All data are complete (N=43), except: maternal education n=42 (2% missing data); hours of sleep in Early-Mid Pregnancy n=41 (5% missing data); hours of sleep in Late Pregnancy n=42 (2% missing data); oral health in Late Pregnancy n=42 (2% missing data); blood pressure in Early-Mid Pregnancy n=30 (30% missing data); blood pressure in Late Pregnancy n=39 (9% missing data); blood pressure across all of pregnancy n=39 (9% missing data). Gestational weight gain group is based on Institute of Medicine guidelines. MN, sample mean; SD, sample standard deviation.
Data were collected on two days in Early-Mid and two days in Late pregnancy and averaged across days to generate Early-Mid and Late means.
Blood pressure was assessed multiple times across pregnancy. Blood pressure category scores were assigned according to the American Heart Association guidelines and were as follows: 0, normal; 1, elevated; 2, hypertension-stage 1; 3, hypertension-stage 2; and 4, hypertensive crisis. See section 2.3 Measures for details.
