Maternal And Neonatal Outcomes

Background: Advanced maternal age is an important predictor for maternal and neonatal outcomes such as maternal mortality, low birth weight, stillbirth, preterm birth, cesarean section and preeclampsia. Objective: To determine the association of advanced maternal age and adverse maternal and neonatal outcomes in Iranian pregnant women. Methods: In this hospital-based cross-sectional study, 5117 pregnant women from 103 hospitals in Tehran, Iran, were participated in the study in 2015. The required data were gathered from hospitals which equipped to the department of obstetrics and gynecology. Advanced maternal age was considered as an independent variable and unwanted pregnancy, preeclampsia, preterm birth, cesarean section and low birth weight were considered as interested outcomes. Results: In our study, the prevalence of advanced maternal age was 12.08%. Advanced maternal age was significantly associated with higher risk of unwanted pregnancy (OR: 1.39, 95% CI: 1.12-1.73), preterm birth (OR: 1.75, 95% CI: 1.28- 2.39) and cesarean section (OR: 1.34, 95% CI: 1.03-1.74). In our study, there was no significant relationship between advanced maternal age and preeclampsia but this relationship could be clinically important (OR: 1.48, 95% CI: 0.99-2.20, P=0.052), and there is no significant relationship between advanced maternal age and low birth weight (OR: 1.08, 95% CI: 0.67-1.74, P=0.736). Conclusion: Advanced maternal age is associated with higher risk of unintended pregnancy, preterm birth and cesarean section but our findings did not support advanced maternal age as a risk factor associated with low birth weight.

Adverse Pregnancy

Background and Aim: Advanced maternal age pregnancy could be referred to as pregnancy after 35 years or older. The prevalence of postponing pregnancies is increasing day by day worldwide. However, limited evidence was found on advanced maternal age pregnancy association with fetal adverse outcomes. The present study aimed to evaluate the frequency of advanced maternal age selected fetal adverse pregnancy outcomes. Place and Duration: Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera for duration of six months from November 2020 to April 2021. Materials and Methods: This single-centered retrospective study was conducted on 220 postpartum women in the study group (≥35 years) and 170 control group postpartum women (20-34 years) who delivered at Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera after 28 gestational weeks. Individuals who met the inclusion criteria were enrolled and sampled based on randomized control sampling technique for both control and study groups. Data extraction checklist and pretested questionnaire were used for data collection from the maternal charts. Adverse pregnancy outcome and advanced maternal age was correlated adjusted relative risks and strength with a 95% confidence interval. SPSS version 20 was used for data analysis and considered p-value >0.05 as a statistical standard. Results: The adverse neonatal outcomes include low birth weight, preterm birth, and stillbirth with a prevalence 38 (17.4%), 46 (20.8%), and 31 (14.2%) respectively in the study group. In the control group, the incidence of low birth weight, preterm birth, and stillbirth was 21 (12.6%), 15 (14.6%) and 6 (3.5%) respectively. The stillbirth (ARR=3.16 95% CI (1.29–6.03) and preterm deliveries (ARR=2.71 95% CI (1.79–3.86) risk had significantly higher prevalence compared to control group advanced age pregnancy. Insignificance association was found between low birth weight and advanced maternal age. Conclusion: Stillbirth and preterm birth was the adverse fetal outcome significantly related with advanced maternal age pregnancy. There was no significant association between low birth weight and advanced maternal age. Keywords: Maternal age, Fetal Adverse Pregnancy Outcomes

Low Birth Weight Infants

In Reply.— The interest of neonatologists in preventing preterm deliveries is remarkable in the United States. In France, where a policy of prevention was developed nationally in 1971, the first impulse also came from the neonatologists and specifically Alex Minkowski, who challenged the obstetricians to propose a real prevention program. The results of this program have now been published.1 incidence of very low birth weight infants in France in 1972 was 0.8 and in 1981 0.4.2
