About one third of infants delivered at 23 weeks' gestation survived to be discharged from neonatal intensive care. More advanced gestational age was associated with increased likelihood of survival. No neonates survived free of substantial morbidity.

Hospital delivery volume is not an independent predictor of cesarean delivery in this population.

Background Growing numbers of reproductive-age U.S. women with chronic physical disabilities (CPD) are becoming pregnant. Little is known about the health conditions causing their CPD. Objectives To identify health conditions causing CPD among reproductive-age women and specifically among currently pregnant women. Research Design Cross-sectional, nationally-representative National Health Interview Survey data from 2006–2011. Subjects 6,043 civilian, noninstitutionalized women ages 18–49 with CPD Measures NHIS asks about various movement difficulties and their underlying causes and about current pregnancy. We used responses from 8 movement difficulty and other questions to identify women with mobility difficulties caused by chronic physical health conditions. Results Among women with CPD, 2.0% report current pregnancy, with pregnancy rates falling monotonically as CPD severity rises. Regardless of pregnancy, 20.8% report 2 causes for their CPD, and 12.7% report 3+ causes; the most common causes are arthritis, back or neck problems, and other musculoskeletal conditions. Compared with nonpregnant women, currently pregnant women report fewer causal conditions: 15.8% report 2 causes and 8.0% 3+ causes; back or neck problems are reported most frequently, followed by musculoskeletal problems and arthritis. Multivariable logistic regression analyses predicting current pregnancy controlling for age category and individual common causes of CPD found that no cause was significantly associated with higher or lower adjusted odds of pregnancy. Conclusions Almost one-quarter of currently pregnant women with CPD report more than one cause for their disability. Further research will need to examine how obstetrical needs vary for depending on the cause of a pregnant woman’s disability.
