39 Weeks Pregnant: Symptoms, Baby Development, and More

The trend towards older parents look set to continue, with more women in their 30s have a baby now than women in their 20s. Is there more risk involved with pregnancy and birth as maternal age increases? We examine the latest evidence.

initial data Latest from the Center for Disease Control and Prevention (CDC) shows that in 2016, for the first time in three decades, the birth rate among women aged 30 to 34 of them among women aged 25 to 29 in United States of America.

The average age of women who had their first child at this time in about 28 years, rising from, and 26.3 in 2014. The experts often focus on the mean or average age of the mother since birth outcomes related to maternal age, such as multiple births and congenital defects.

The study reports that people may put off the old man to 35 years or more for a number of reasons.

For these reasons include women reach the level of higher education, build their careers, methods of improvement, shifting social and cultural development has left women do not feel ready to have a child, lack of child, benefit levels low not flexible workplace policies, economic uncertainty or housing, and unempl oyment.

Another reason for women going through pregnancy at a later date could be down to increased fertility choice, like IVF.

Pregnant women over the age of 35 and have their first baby has been referred to as advanced maternal age (AMA) or older mothers, or they were referred to as primigravidae old or older primipara. The term "aging" and "old" has negative connotations for someone only 35 years old. Are these terms is unfounded, or whether to be more than 35 poses serious risks for the mother and baby?

Everyone is aware of the ticking of the biological clock, but not the 35th birthday you are very special milestone in biology? Did you hit 35 and suddenly become a "high risk" last night?

Women gave a healthy baby throughout the 30s and beyond them. Age 35 only age to be more worthy of discussion.

While this risk becomes a little more likely after hitting a 35-year-old, this does not mean that they will have a significant impact on everyone in their mid-thirties and older.

Women are born with all the eggs they will ever have. As a woman ages, the chances that they will get pregnant diminish due to declining number of remaining eggs and their diminished quality.

Fertility also decreased in men with age due to reduced sperm count, motility, and semen volume. These age-related factors combined may make it harder for women to get pregnant.

One, published in The New England Journal of Medicine, found that among women who received artificial insemination, 74 percent of those under 31 years old become pregnant within one year. However, this decreased to 61 percent of individuals between the ages of 31-34, and then decreased up to 54 percent of women age 35 and over.

particular genetic risk is present more often in pregnancy a woman's age. For example, the level of having a baby with Down syndrome precipitated by maternal age.

While the rate of embryo has Down syndrome at 10 weeks of pregnancy is a sign at the age of 25, this increases to 1 in 686 at age 30 and 1 in 240 at age 35. At the age of 40, increased Down syndrome level was 1 in 53, and dropped to 1 in 19 embryos at the age of 45.

A was published in Nature Communications set out to investigate why older mothers have become high risk of childbearing with a congenital anomaly characterized by an abnormal chromosome number.

researchers from Albert Einstein College of Medicine of Yeshiva University in New York learned that the process of genetic recombination may be responsible for an increased risk of conditions such as Down syndrome.

Recombination is the process in which pairs of chromosomes exchange genetic material before separating. The team found that the older the mother, the recombination process can be less regulated, which can cause an abnormal number of chromosomes in the sex cells or large chromosomal rearrangements.

The risk of miscarriage climbs gradually with maternal age. published in the BMJ shows that the risk of miscarriage is about 8.9 per cent for women aged 20 to 24 years and increased to 74.7 percent for individuals aged 45 years or above. Declining quality of female eggs isthought responsible for a higher rate of miscarriage.

stillbirth are more likely in older women than younger women. A published in the Canadian Medical Association Journal found that stillbirths are about 1.2 to 2.23 times higher in older women.

Another, examined data from 385 120 pregnancies in the UK, observed that the rate of stillbirth was 4.7 per 1,000 for women aged 18 to 34, 6.1 per 1,000 between the ages of 35 and 40, and 8, 1 per 1,000 women aged 40 and over.

In addition, the rate of stillbirth was higher in people having their first child and even higher in first time mothers aged 35 years or more.

Women aged 35 years and older is often recommended to be induced when they are approaching their maturity date due to the increased risk of stillbirths with a gestational age. Neighborhood women under 35 years old have a stillbirth during the 39 and 40 weeks of pregnancy, compared with 1.4 in 1000 women aged 35-39, and 2 in 1,000 women at age 40 and above.

The reason for the stillbirth rate was increased with maternal age is currently unclear.

comparing complications of pregnancy among women aged 18 to 34 years, 35 to 40 years, and 40 and over, found a small increase in complication pregnancy- and birth-related with age.

researchers identified an increased risk of pregnancy, placenta previa, breech position of the baby, an emergency cesarean births, PPH, preterm birth, low birth weight, and high birth weight. Others have found that the risk of maternal mortality increases with age.

presented at the American Stroke Association's International Stroke Conference 2016 revealed that compared with women who had a pregnancy at a young age, pregnant women aged 40 and older are at greater risk of ischemic, hemorrhagic stroke, and death from cardiovascular disease.

"We already know that older women are more likely than younger women to experience health problems during their pregnancy," said Dr. Adnan I. Qureshi, director of the Zeenat Qureshi Stroke Institute in St. Cloud, MN. "Now, we know that the consequences of that later pregnancy stretch years into the future."

Dr. Qureshi and colleagues found that all risks, except for hemorrhagic stroke, which is explained by the well-known risk factors for cardiovascular disease - such as, diabetes, and high -. Pregnant women face old

The latest, published in The Journal of Physiology highlights why women aged over 35 years are more likely to face birth complications. Researchers from King's College London in the United Kingdom found that in a mouse model, that the influence of maternal age structure of the uterus.

In the group of mice that represent women aged over 35 years, the nature of muscle contraction in the uterus is found disturbed, less sensitive, and has reduced the number of mitochondria, which all show that the muscles of the uterus less able to contract properly , Furthermore, the researchers found changes in the signal, which triggered a delay in the work force.

"Our research highlights that there is a key physiological and cellular changes associated with advancing maternal age produces labor dysfunction," said Dr. Rachel M. Suku, principal investigator of the study at King's College London. "The delivery time and labor progress is directly related to maternal age, and this can lead to complications during the birth."

Babies born with low birth weight often experience more respiratory problems, cognitive, and neurological, while premature babies are more likely to have heart defects, brain damage, lung disorders, and delayed development.

Several studies have shown that there is an increased risk of low birth weight (below 2.5 kg) and premature birth (before 37 weeks of pregnancy) for women aged 35 years or older. However, recently - conducted by Mikko Myrskylä, director of the Max Planck Institute for Demographic Research, and Alice Goisis, of the London School of Economics in England -. Showed that maternal age is not an excuse

study published in the American Journal of Epidemiology, found that the reason is more likely related to individual circumstances or behavior is more common in older adults.

Potential candidates this factor could be a fertility problem, which is associated with a poor outcome is born, the mother, and unhealthy behaviors.

"Our findings indicate that women should not worry about their age per se when considering having a child, "said Myrskylä. "It appears that the individual life circumstances and choice behavior is more important than age."

People decide whether to postpone the parents have to take into account the decline in fertility and an increased risk of miscarriage and birth complications. Stillbirth relatively rare, but the risk remains high for women who are older than their counterparts who are younger and improved in the last weeks of pregnancy.

There are, of course, plenty of plus points from the mother postpone until after the age of 35. Children of older mothers have had less trouble behavioral, social, and emotional.

according to another conducted by Kieron Barclay Myrskylä and colleagues, at the London School of Economics, who was born and then also associated with being healthier, higher, and acquire more education.

"benefits associated with being born in one year then outweigh the individual risk factors arising from being born to older mothers. We need to develop a different perspective on advanced maternal age. expectant parents are usually unaware of the risks associated with pregnancy, but they are less aware of the positive effects. "

Despite the risks, many women aged 35 and older will have a normal pregnancy with some birth complications, and went to give birth to a healthy baby.
