Investigation of the Maternal and Neonatal Factors Affecting the Apgar score of Newborns: A Case-Control Study

Background: Apgar score is a method for clinical evaluation of neonate at birth, and predicts their clinical conditions and physical or mental development. This study aimed to investigate the relationship between some neonatal and maternal factors during pregnancy on the Apgar score. Materials and Methods: This case-control study was conducted on ۲۳۴ neonates born in Ilam hospitals during ۲۰۱۵-۲۰۱۶. The case group included ۸۱ neonates with Apgar score Results: The mean maternal weights in the case and control groups were ۶۶.۸ ± ۱۳.۵ and ۶۷.۱ ± ۱۱.۱ Kg, respectively. The mean± SD for maternal age ۲۹ ± ۵ vs. ۲۹ ± ۵.۷ years, marriage age ۲۲ ± ۳ vs. ۲۲.۲ ± ۴.۹ years, BMI ۲۴.۵±۳.۲ vs. ۲۶.۱ ± ۴.۱ and weight gain during pregnancy ۱۳.۸ ± ۶.۲ vs. ۱۲.۷ ± ۶.۸ kg among cases and controls, respectively. The odds ratio for the following factors was significantly higher among cases than the control group: preterm delivery (OR: ۳.۳, ۹۵% CI: ۱.۲-۱۷), twin birth (OR: ۸.۹, ۹۵% CI: ۲.۶-۲۷.۲), abnormal presentation of the fetus (OR: ۶, ۹۵% CI: ۲.۳-۱۵.۶), birth weight (OR: ۶.۹, ۹۵% CI: ۱.۴-۲۸.۶), and placental abruption (OR: ۹.۴, ۹۵% CI: ۲.۲-۲۲.۵) for Apgar score at five minute.   Conclusion: Based on the findings of the present study, preterm labor, multiple birth, and abnormal fetal presentation, and low birth weight, premature rupture of membrane, placental abruption and anemia, led to an increase in Apgar score less than ۷.
