Clinical Report: Impact of Maternal Age 30 to 34 on Negative Perinatal Outcomes
Overview
This meta-analysis examines the association between maternal age 30-34 years and adverse perinatal outcomes, including congenital birth defects, stillbirth, and preterm birth.
Background
The trend of delayed childbearing has led to an increase in pregnancies among women aged 30-34 years. Understanding the risks associated with this age group is crucial for clinical counseling and public health guidelines, as they represent a significant portion of births in high-income countries. Previous research has often overlooked this specific age cohort, necessitating a focused analysis of their perinatal outcomes.

Key Findings
Maternal age 30-34 years is associated with a higher risk of congenital birth defects (OR 1.10).
There is a significant association with Down syndrome (OR 1.97).
No significant association was found for structural birth defects (OR 0.99).
Stillbirth did not show a significant association (OR 1.07).
Other outcomes such as preterm birth, low birthweight, neonatal mortality, SGA, and IUGR were not significantly associated with maternal age 30-34.
Clinical Implications
Healthcare providers should be aware of the increased risk of congenital birth defects in pregnancies among women aged 30-34 years.
Conclusion
Maternal age 30-34 years is associated with a higher risk of congenital birth defects, while other adverse perinatal outcomes do not show significant associations.
