ability to estimate blood loss. All data were analyzed using chi square test.RESULTS: Underestimation was significantly higher at cesarean, occurring 65% versus 39% of the time at vaginal delivery (P5.002). Contrary to our hypothesis, overestimation was significantly higher at vaginal delivery, occurring 51% versus 33% of the time at cesarean (P5.007). Differences in resident versus attending ability to estimate blood loss did not reach statistical significance.CONCLUSION: Physicians significantly overestimated blood loss at vaginal delivery, and significantly underestimated blood loss at cesarean delivery. There was no difference in resident versus attending ability to estimate blood loss.
length of hospital stay. Spearman's correlation coefficient, analysis of variance, and x 2 were used for statistical analysis.RESULTS: Across the three groups, the neonatal birth weight significantly correlated with maternal weight gain in pregnancy and weight gain at delivery but did not correlate with maternal baseline weight and BMI at initiation of prenatal care (P5.04). The mode of delivery, the rate of NICU admission, and length of stay did not demonstrate any association with either baseline BMI or BMI at delivery across all three groups.CONCLUSION: Maternal BMI at delivery and not baseline BMI at initiation of prenatal care is directly associated with neonatal birth weight in pregnancies complicated by maternal obesity. Neither BMI at initiation of prenatal care nor at the time of delivery is associated with mode of delivery, rate of NICU admission, or neonatal hospital stay.
INTRODUCTION: The prevalence of smoking in teen mothers is high, 15% nationally and 34% in Ohio. Both young maternal age and cigarette smoking are independently associated with adverse pregnancy outcomes. We aim to identify factors associated with smoking cessation and quantify their relative effect in teen pregnancies.
METHODS:A population-based retrospective cohort study of all Ohio live births, 2006-2012. Teen mothers aged younger than 20 years who quit smoking in the first trimester were compared with a referent group of teens who smoked throughout pregnancy. Logistic regression assessed the association between demographic and prenatal factors and odds of smoking cessation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
