Clinical aspects of pregnancy after the age of 35 years: a review of the literature.
The objective of this report is to provide an update of our current knowledge about the impact of maternal age on pregnancy outcome. Pregnancy in women > or =35 years old is associated with a higher maternal and perinatal mortality. The older gravida also has a higher chance of being delivered by Caesarean section. Most of the complications associated with older age are caused by age-related confounders such as leiomyomas, type II diabetes, hypertension and multiparity. Diabetes and hypertension increase almost linearly with age. Pregnant women with diabetes or hypertension are at increased risk of adverse pregnancy outcome irrespective of age. The currently available literature indicates that premenopausal pregnant women of advanced age who are in good health do not need special care besides the normal obstetric practice. At present, establishing pregnancy in postmenopausal women is more an ethical than a medical issue, partly because the information reported on pregnancy in postmenopausal women is insufficient to determine a reliable risk profile. In these women cardiovascular ageing accelerates. Therefore, until proven otherwise, postmenopausal women should be considered particularly at increased risk for vascular complications during pregnancy. This risk is likely to increase progressively with the number of years elapsed since the onset of postmenopause.
