This study aimed to evaluate the effect of first trimester bleeding on newborns Apgar scores. Methods A retrospective study was conducted on pregnant women who delivered at Shahid Sadoughi hospital in Yazd, Iran, between 2022 and 2023. Only singleton, nulliparous, non-diabetic women were included. Participants were divided into two groups: the exposure group (Bleeding Group) and control Group (Non-Bleeding Group), based on archived records. Apgar scores recorded at the first and fifth minutes after birth in newborns file were compared between groups. Results A total of 992 women were included, with 218 in the exposure and 774 in the control groups. The incidence of a first-minute Apgar score <7 was significantly higher in the bleeding group compared to controls (22.5% vs. 6.2%, p = 0.02). However, there was no significant difference in five-minute Apgar scores between groups. Conclusion This study demonstrated a positive association between first-trimester vaginal bleeding and a low first-minute Apgar score in newborns.
