Understanding So-Called “Geriatric Pregnancy”

Risks to maternal health and pregnancy do increase with age, but can be managed.

The United States birth rate is in decline, but there is one group bucking the trend. According to statistics from the Centers for Disease Control, births to women from the ages of 35 and 45 have increased slowly but steadily since the 1990s. That means more women are having what was once dubbed a geriatric pregnancy — a phrase meant to highlight high risk. And while the term geriatric pregnancy has fallen out of use, and the increased risks are manageable, the negative connotations still make pregnancy nerve wracking for women in their late 30s and early 40s.

Yes, it’s true that some birth risks increase with maternal age. But OB/GYNs and fertility experts are clear that with preparation and thoughtful care, pregnancy for women approaching mid-life can be as successful and healthy as any other.

What Is a Geriatric Pregnancy?

The currently preferred term is “advanced maternal age.” This simply means that an expectant mother has made the choice to conceive and carry a child to term after the age of 35-years-old.

“The term geriatric pregnancy is not an accurate one since geriatrics involves medical treatment of the elderly and pregnancy is not an issue that affects the elderly,” explains Dr. Barry Witt, a board-certified reproductive endocrinologist, Chief Medical Director with WINFertility and Medical Director of Yale Medicine Greenwich Fertility Center. He also notes that as women age it becomes harder to conceive, so it helps to make a plan earlier in life.

Still, women make the choice to conceive later in life for a variety of reasons. Some choose to wait until they’ve developed a career before having a child. Some women are waiting for a perfect partner. Some women struggle to conceive any earlier and become pregnant through fertility interventions. Some have stored eggs for a later date. All are normal and can lead to delivering a healthy, happy baby.

“Women of advanced maternal age may safely conceive and have healthy babies in most cases,” Witt says. “By decreasing the risks through healthy lifestyle and optimizing health prior to pregnancy, and by having regular prenatal visits, most complications can be identified early and appropriately treated.”

What Are the Risks?

As maternal age increases the risks for moms-to-be and their babies. genetics and maternal health. For the mother, pregnancy increases the risk of developing age-related health conditions that could affect her ability to carry the child to term. These include diabetes and a condition related to high blood pressure called preeclampsia.

For the baby there is an increased risk of genetic abnormalities. “Down’s syndrome incidence for women conceiving in the early 30’s is about one in 800,” explains Mary Jane Minkin, Clinical Professor of Obstetrics and Gynecology at Yale University Medical School. “Incidence at age 40 is about one in 100; and at 44, it’s about one in 25.”

There is also an increased risk of having multiples (twins, triplets or more) as a woman’s ovaries tend to release multiple eggs as she gets older. Delivering multiples is associated with increased risk of preterm birth.

Finally there are also higher risks of miscarriage. But it’s important to note that this is not as much about a woman’s’ ability to stay pregnant as it is the viability of the eggs. Older women who use eggs of younger women to conceive actually have lower rates of miscarriage than their peers.

Advanced Maternal Age Risks are Manageable

Minkin notes that there is genetic testing available to mitigate and understand the risks. She also explains that mothers arriving at pregnancy later in life will increase chances of a safe successful birth through thoughtful preparation.

There are certainly things that women can do to decrease risks,” she says. “Most significantly. achieving an ideal body weight is very helpful, as is getting into great physical shape. So a good exercise regime is also helpful.”

But those aren’t the only lifestyle changes that can improve outcomes for women having children later in life. “Reducing the use of alcohol, tobacco, marijuana, or unhealthy habits in advance of getting pregnant can help to reduce risks,” Dr Witt says. “Use of prenatal vitamins with folic acid can help prevent birth defects.”

Some Reassurance

As with most physically intense activities, pregnancy becomes more difficult as humans age. But it’s important to understand that knowing the risks can help alleviate the risks. That’s why it’s important to get care early, stay healthy and keep in touch with health care providers.

Every pregnancy is different. Having a healthy baby, no matter what the age, is a matter of preparation, genetics, support and good guidance.
