| Summary: | Objective Vaginal bleeding is a relatively common problem during pregnancy, with up to 25% of women experiencing some level of bleeding or spotting during pregnancy. Although not always a concern, pregnancy-related vaginal bleeding may detrimentally impact maternal and fetal health, and can arise at any stage during the pregnancy, usually linked with preterm labor, miscarriage, placental abnormalities, or implantation bleeding. As vaginal bleeding may compromise newborn health outcomes, for example, leading to low birth weight and neonatal intensive care unit (NICU) hospitalizations, it is imperative to understand the etiology of the bleed and effectively manage the patient’s condition. Thus, the aim of this study was to evaluate the prognostic value of vaginal bleeding as an indicator for at-risk pregnancies, aiming to elucidate its association with perinatal outcomes and pregnancy complications. Methods Consecutive pregnant female patients, aged 16–47 years, were included in this retrospective cohort study, and categorized into those with or without pregnancy-associated bleeding. Between-group differences and correlations in pregnancy complications and perinatal outcomes were statistically analyzed. Results Among a total of 441 patients, the incidence of vaginal bleeding was 74.4%, predominantly occurring in the first trimester (67.1%). No significant association was found between bleeding and maternal age, parity, abortion history, or total number of pregnancies. Educational level varied, with 64.9% of moderate education level experiencing bleeding. Pre-pregnancy comorbidities, such as diabetes, hypertension, and hypothyroidism, were not significantly correlated with bleeding. However, a history of infertility and progesterone treatment during pregnancy was significantly associated with bleeding episodes. An increased risk for NICU admissions and conditions such as respiratory distress in neonates was found, alongside a significant association with post-delivery bleeding and premature labor in the later trimesters. Conclusions Vaginal bleeding during pregnancy was not found to be significantly associated with maternal age, parity, abortion history, or total pregnancies. Nonetheless, the findings suggest a significant relationship between bleeding episodes and a history of infertility or progesterone treatment during pregnancy. Additionally, pre-pregnancy comorbidities, including diabetes, hypertension, and hypothyroidism were not associated with pregnancy bleeding. However, the latter was associated with increased risk of post-delivery bleeding, premature labor, and neonatal complications, such as respiratory distress and NICU admissions. |
