According to many research and articles, the best age to give birth is in your twenties. This is because things can become complicated if you become a mother too late. However, an increasing number of people are deferring having children until they are more mature, and there is some good news for them: a study discovered that having a child after the age of 30 may be the key to having smarter children.
Most studíєs on older mothers focus on the risks for the mothers, but few look at the benefits for the children whose mothers are more aged. However, a study conducted in the United Kingdom looked at approximately 18,000 children enrolled in the Millennium Cohort Study (UK) to see a link between the age at which a mother gives birth and the child’s development. According to this study, mothers who have their first child between the ages of 30-39 are more likely to have intelligent children than mothers between the ages of 20-29.
Children born to mothers in their 30s perform better on cognitive tests at five than children born to younger mothers. This is consistent with the findings of a Swedish study, in which the Grade Point Average (GPA), which measures how well people perform overall in school, was studíєd on 16-year-olds. It turns out that children born to mothers aged 35-39 when they gave birth to teenagers have the highest GPA, while children born to mothers aged 30-34 at the time of delivery have the second highest.
So the question now is why the age of a mother when she gives birth may influence how intelligent a child is. According to Alice Goisis, one of the UK study’s researchers, “First-time mothers in their 30s, for example, are more likely to be more educated, have higher incomes, are more likely to be in stable relationships, have healthier lifestyles, seek prenatal care earlier, and have planned their pregnancies.”
The same study discovered that postponing pregnancies until after 40 may not result in a smarter child. However, this could be because only about 50 mothers aged 40 and up were included in the study.
In the Swedish study, 16-year-olds born to mothers aged 40-44 outperformed teens born to mothers in their twenties. Those born to mothers in their forties and fifties fared only slightly worse than mothers in their twenties and thirties and fared better than those born to mothers in their twenties and thirties.
Another study found conflicting evidence regarding the impact of maternal age on a child’s abilities. Using data collected between 1958 and 1970, researchers discovered that 10- and 11-year-old children born to mothers between the ages of 35 and 39 performed worse than those born to mothers between 25 and 29.
