Down syndrome occurs in people of all races and economic levels. The risk increases with the mother's age (1 in 1250 for a 25 year old mother to 1 in 1000 at age 31, 1 in 400 at age 35, and about 1 in 100 at age 40).
Which complications are more common in women over 40? Older mothers seem more likely to complications problems in pregnancy and childbirth. You're more likely to experience problems such as high blood pressure, diabetes, placental problems and birth complications.
Forty-something pregnancies are no longer considered extremely unusual. In 2016, for the first time, women giving birth in their 30s outnumbered women who gave birth in their 20s. And birth rates have gone up the fastest for women over 40, rising 19 percent since 2007.
Pregnancy in Your 40s
If you get pregnant after 35 years old, experts call this an “advanced maternal age” pregnancy. But it's still possible to get pregnant and deliver a healthy baby in your 40s. Childbirth at older ages has become more common too. Since the 1990s, birth rates in people aged 40-44 have gone up.
Women who are 35 years or older when they become pregnant are more likely to have a pregnancy affected by Down syndrome than women who become pregnant at a younger age.3-5However, the majority of babies with Down syndrome are born to mothers less than 35 years old, because there are many more births among younger women ...
An adequate intake of folic acid during pregnancy, believed to protect against neural tube defects (NTDs) in babies, may also help prevent Down's syndrome, researchers report in The Lancet this week.
About 95 percent of the time, Down syndrome is caused by trisomy 21 — the person has three copies of chromosome 21, instead of the usual two copies, in all cells. This is caused by abnormal cell division during the development of the sperm cell or the egg cell.
Not optimal, but not selfish either
The point here is to look at some of the things which people say are selfish and realize that, while it may not be the “optimal conceiving time” there are plenty of reasons to have a child over forty and those reasons are not by definition selfish.
Definition of geriatric pregnancy
We define advanced maternal age (formerly geriatric pregnancy) as those who are 35 years or older at their estimated delivery date. Historically, pregnancies at this age or older are considered at higher risk – for patient and fetus – for various reasons.
So on average, when we look at large groups of women, of women who want to conceive at age 40, about half will get pregnant naturally. But that decreases quickly to perhaps 20% to 25% by age 42 to 43. And by age 45, it's quite rare to become pregnant naturally. Dr.
Your risk for other complications increases
This is one of the reasons women over 40 are at higher risk for pre-eclampsia (high blood pressure and protein in the urine during pregnancy, which can be life-threatening) and gestational diabetes (abnormally high blood sugar during pregnancy).
Of course, as women age, the odds of conceiving also gradually lower. The ideal childbearing age is often considered to be in the late 20s and early 30s. Pregnancies later in life could come with some health risks. However, age is just one factor when it comes to giving birth to a child.
Down's syndrome and other chromosomal anomalies
The likelihood of Down's syndrome continues to increase as a woman ages. So by age 42, the chance that a pregnant woman will have a baby with Down's syndrome is one in 60. By age 49, the chance is one in 12 .
Luckily, while the risks of complications are lower in your 20s and 30s, you can have a healthy pregnancy in your 40s, particularly if you are otherwise in good health and get regular prenatal care.
Down syndrome occurs in people of all races and economic levels. The risk increases with the mother's age (1 in 1250 for a 25 year old mother to 1 in 1000 at age 31, 1 in 400 at age 35, and about 1 in 100 at age 40). However, 80% of babies with Down syndrome are born to women under age 35 years.
You may have heard that a woman's risk for complications during pregnancy goes up after age 35. The fact is that most women in their 30s and 40s have healthy pregnancies and healthy babies. To ensure a healthy pregnancy, you should do what any woman should do: Prepare for your baby with healthy lifestyle choices.
Birth defects.
If you are age 35, the risk increases to 1 in 400. By age 45, it is 1 in 30.
This is because a woman's eggs age as she ages. Older eggs are more prone to forming embryos with either too many or too few chromosomes. This is the reason why older women have a greater rate for infertility, miscarriages and babies with chromosomal birth defects.
Can you have a normal, healthy pregnancy at 45? Yes. Assuming you have top-notch prenatal care during your pregnancy, you eat well and have a healthy lifestyle, you take care of yourself during your nine months, and you come into your pregnancy as healthy as can be, your pregnancy can be problem-free.
The study confirmed that women over 40 do have the highest risk of preterm births: 7.8 percent of pregnancies in this age group resulted in preterm births and 1 percent ended in extremely premature deliveries.
It occurs because either the egg or the sperm involved in the formation of the embryo carried an extra copy of Chromosome 21. The vast majority of cases (about 90%) of Down syndrome are due to a problem with the egg. A small percentage of all eggs (and sperm) have abnormal chromosome arrangements.
“We are presently studying whether stress can be directly linked to the down syndrome. Our observations do seem to suggest that stress is a factor which can play a significant role and we are collecting evidence to prove it.
There is nothing you can do to prevent or avoid your child having Down syndrome. However, your risk is lower if you have children at a younger age.
