Women 35-39 years old have a 2-3 fold higher risk of pregnancy-related death than women in their twenties, and the risk is even more dramatic for women 40 years and older.

Univariate and multiple logistic regression analyses were preformed to investigate the association between maternal age and various relevant outcomes. Results: Women aged 35 years or older had an increased percentages of gestational hypertension (18.8% vs 9.6%; p=0.02) and diabetes in pregnancy (3.7% vs 1.4%; p=0.08) compared with women younger than 35 years. There were no differences between the two age groups in Apgar score at 1 min, antepartum hemorrhage, preterm labor, PROM, fetal distress, perinatal death, and postpartum hemorrhage. Conclusion: Advanced maternal age was shown to be independently associated with low birth weight, preterm labor and rate of cesarean delivery.
