Abstract
Aims: In recent years, very early pregnancies and very advanced pregnancies have increased. In our study, we aimed to compare these groups in terms of maternal and fetal risks.
Materials and Methods: This study retrospectively were compared the perinatal outcomes of women of reproductive age in 80 early adolescent pregnant (16 years and younger) and 67 older pregnant women (45 years and older) followed in Siirt Training and Research Hospital between 2017 and 2021 in Siirt Training and Research Hospital (Siirt, Turkey). In cases gravida, parity, hemogram, biochemistry, urine, week of birth, fetal weight, gender, APGAR 1-5. min, mode of delivery (vaginal delivery/ cesarean section), miscarriage, neonatal death, premature rupture of membranes (PROM), premature birth, placental ablation, fetal distress, intrauterine death, gestational diabetes mellitus (GDM), preeclampsia, surmaturation, polyhydramnios , oligohydramnios, presentation anomaly, multiple pregnancy, intrauterine growth retardation (IUGR), postpartum hemorrhage, placenta previa, maternal and fetal outcomes in three pregnant groups were evaluated.
Results: Normal spontaneous vaginal delivery (NSVD)/Cesarean section (C/S)" parameter was found to be significantly higher in pregnant women aged 45 and above, while it was found to be significantly lower in the group aged 16 and below(p<0.0001). Spontaneous abortion, on the other hand, was not found significantly in the 16-year-old and younger group compared to the other groups, while it was significantly higher in pregnant women aged 45 and above(p<0.0001).The incidence of GDM was significantly higher in pregnant women aged 45 and over, but it was not determined in pregnant women aged 16 and younger (p=0.003). The incidence of preeclampsia was also found to be significantly higher in pregnant women aged 45 and over (p<0.0001). The incidence of polyhydramnios was significantly higher in the risky pregnant group than in the control group (p=0.015). The incidence of presentation anomaly was found to be significantly higher in pregnant women aged 45 and over (p=0.012). No statistically significant difference was found in other parameters.
Conclusion : Both early adolescent pregnancies and very advanced age pregnancies have their own problems. The obstetrician should be aware of these in his approach to both groups.
