Umbilical artery pulsatility index (UA\u2010PI), middle cerebral artery pulsatility index (MCA\u2010PI), and uterine artery pulsatility index (UtA\u2010PI) were measured. The cerebroplacental ratio (CPR) was calculated as MCA\u2010PI\/UA\u2010PI, and CPUR was calculated as CPR\/mean UtA\u2010PI. CAPO was defined as the presence of at least one of the following: preterm birth, low birth weight, small for gestational age, low fifth\u2010minute Apgar score, abnormal umbilical artery cord blood gas values, or neonatal intensive care unit admission.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Women with moderate anemia had significantly lower gestational age at birth, lower birth weight, lower first\u2010 and fifth\u2010minute Apgar scores, and worse umbilical artery cord blood gas parameters than controls. The prevalence of small for gestational age neonates, neonatal intensive care unit admission, and CAPO increased progressively with anemia severity. UA\u2010PI and UtA\u2010PI were significantly higher, whereas CPR and CPUR were significantly lower in pregnancies complicated by moderate anemia. Hemoglobin alone showed moderate predictive performance for CAPO prediction (AUC\u2009=\u20090.724, 95% CI: 0.643\u20130.801,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).

In multivariable logistic regression analysis, hemoglobin level, gestational age at birth, UA\u2010PI, UtA\u2010PI, and CPUR remained independent predictors of CAPO.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Maternal anemia is associated with impaired uteroplacental and fetoplacental hemodynamics and increased adverse perinatal outcomes.
