Most studies in this area have focused on adults, with comparatively fewer related to children, particularly newborns. The aim of this study was to investigate the association between ABO blood groups and neonatal clinical outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective descriptive study assessed the association between neonatal ABO blood groups and clinical outcomes among infants admitted to the Neonatal Intensive Care Unit of Imam Khomeini Hospital in Ahvaz, Iran, over 2 years (2023\u20132024). Infants were categorized by blood group (O vs. non\u2010O). Data on gestational age, delivery mode, intubation needs, sex, Apgar scores, birth weight, mechanical ventilation, proven sepsis incidence, surfactant use, antibiotic therapy, hospitalization duration, and mortality were collected and compared based on their blood groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Medical records of 545 infants were analyzed; blood group O was the most common (38.2%), followed by B (29.2%), A (23.5%), and AB (9.2%). Rh\u2010positive infants comprised 92.8% of the cohort. No statistically significant associations were found between blood group and gestational age, birth weight, Apgar scores, or intubation needs. However, male infants were significantly more prevalent in non\u2010O blood groups (60.5% vs. 39.5%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001). Clinical outcomes, including surfactant use, mechanical ventilation, sepsis, and mortality, did not differ significantly between the two groups.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The study highlights a sex disparity in blood group distribution but suggests that ABO blood type was not associated with differences in neonatal morbidity or mortality in unadjusted analyses in this population.
