The perfect age for women to give birth is a slim 9-year window.

When it comes to the best age to have a baby, there is a Goldilocks zone of nine years for ladies.

That’s the conclusion of a study of more than 31,000 births that found girls aged 23 to 32 were at the highest risk of birth defects.

Giving birth in one’s teens or early twenties increased the chance of having a child with central nervous system defects that hindered the growth of the mind and spine, while adult pregnancy was most closely associated with birth defects in the head, neck, eyes and ears. .

The researchers said their findings pointed to the need to modernize safety screening tools for pregnant women as the reproductive age in the developed world continues to age over the past decade.

The lowest 10-year hazard interval was between 23 and 32 years, and the reduction and better age at birth were almost as dangerous

For men, the first baby together is now obsolete at 26.4 years, while ladies give birth for the first time at 23.7 years. Both have grown dramatically over the past 20 years

The report further provides practical explanations of the completely different dangers by age group, noting that younger mothers are sometimes unprepared for pregnancy and suffer from particularly unhealthy lifestyle elements related to drug and alcohol use.

Older women are exposed longer to environmental stressors linked to air pollution, which scientists say may contribute to the risk of many birth defects.

The study comes as the typical age of the youngest mothers in America reaches an all-time high.

American ladies now give birth for the first time in their 30s 27.2 years in 2000 and 24.6 years in 1970.

The increasing age of first-time mothers is due to quite a number of elements, as well as social and cultural changes in the form of delayed marriage and additional time spent on leisure and travel, women’s greater labor market prospects and monetary constraints.

Scientists from Semmelweis University in Hungary analyzed knowledge from 31,128 pregnancies with confirmed non-chromosomal birth defects registered in the Hungarian Congenital Anomaly Case Control Surveillance between 1980 and 2009.

They contrast this knowledge with more than 2.8 million births registered at the Central Statistical Office of Hungary during the same 30-year interval.

Overall, the chance of non-chromosomal birth defects increased by a few fifths in women younger than 22 years. For women over the age of 32, this danger has increased by about 15 percent.

The most common and life-threatening problems affect the fetal circulatory system and, in mothers younger than 20, the central nervous system.

Younger mothers were 25% more likely to have central nervous system defects in their infants compared to older mothers.

Women who gave birth before the age of 20 were at a much higher risk of central nervous system abnormalities due to problems with the growing fetal brain and/or spinal cord, resulting in severe conditions consistent with spina bifida.

Older mothers again confirmed a 100% higher risk of having a child with deformities of the eyes, ears, face and neck, which are related to the collective fusion of the bones of the skull or face of the child too early or irregularly.

This can cause the child’s ears to be set abnormally low on the top, eyes to be medically small, or vocal cord paralysis.

Women in the older spectrum were also at increased risk of coronary heart defects and additional urinary tract malformations.

And older mums are significantly more likely – 45pc in fact – to give birth to a baby with a cleft lip and palate, while a young mum will have a 9pc increased risk.

Although young mothers were 23 percent and 15 percent more likely to have gastrointestinal birth defects than older mothers, the risk of fetal genital abnormalities was slightly higher for older mothers.

dr. Boglárka Pethő, assistant professor at Semmelweis University and first author of the study, said: “We can only speculate why certain age groups are more likely to develop non-chromosomal birth defects.

“For new mothers, it can mainly be lifestyle factors (such as smoking, drug or alcohol use) and the fact that they are often not ready for pregnancy.

“In maturing mothers, the accumulation of environmental influences such as exposure to chemicals and air pollution, impairment of DNA repair mechanisms, and aging of the oocytes and endometrium may also play a role.”

Previous analysis has confirmed that maternal age additionally increases the chance of having a child with Down syndrome, a case of genetic dysfunction. But much less analysis has been done on non-genetic abnormalities

The variety of American ladies with at least one baby has dropped to simply 52.1pc, while the variety of males has dropped to 39.7pc in 2019.

The report is printed in the magazine BJOG: International Journal of Obstetrics and Gynaecology.

In the mid-twentieth century, the typical lady gave birth to three to four youngsters during her child’s growing season. Just 1.6 young today, the lowest rate recorded since records were first kept in 1800.

Women who become pregnant and give birth after the age of 35 tend to have particularly harmful pregnancies. Older mothers may also be at increased risk of miscarriage, hypertension, gestational diabetes, and difficult births.

Findings related to non-genetic delivery defects that are not influenced by maternal genes.

Previous analysis has confirmed a hyperlink between older maternal age and safe genetic situations, particularly Down’s syndrome, the probability of which will increase from about 1 in 1,250 women who conceive at age 25 to about 1 in 100 ladies who convert. pregnancy at age 40.

prof. Nándor Acs, director of the Department of Obstetrics and Gynecology at Semmelweis University, said: “Non-genetic birth defects can often develop because the mother is exposed to long-term environmental effects.

“As the reproductive age in the developed world is dramatically reduced, it is more important than ever to respond appropriately to this trend.”
