Logistic regression analyses identified independent predictors of EWL (\u226510% of birth weight) by using a preplanned theoretical model.<\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n EWL occurred for 18% of infants who received no or minimal (\u226460 mL total since birth) formula (n = 229), including 19% of exclusively breastfed infants (n = 134) and 16% of infants who received minimal formula (n = 95). In bivariate analyses, EWL was associated (P &lt; .05) with higher maternal age, education, and income levels, hourly intrapartum fluid balance, postpartum edema, delayed lactogenesis (&gt;72 hours), fewer infant stools, and infant birth weight. In multivariate logistic regression analysis, only 2 variables predicted EWL significantly, namely, intrapartum fluid balance (adjusted relative risk for EWL of 3.18 [95% confidence interval [CI]: 1.35\u201313.29] and 2.80 [95% CI: 1.17\u201311.68] with net intrapartum fluid balance of &gt;200 and 100\u2013200 mL\/hour, respectively, compared with &lt;100 mL\/hour) and delayed lactogenesis (adjusted relative risk: 3.35 [95% CI: 1.74\u20138.10]).<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS:<\/jats:title>\n EWL was more common in this population than reported previously and was independently related to intrapartum fluid balance. This suggests that intrapartum fluid administration can cause fetal volume expansion and greater fluid loss after birth, although other mechanisms are possible.<\/jats:p>\n
