Since she became pregnant, her little niece has been "tortured" by morning sickness.
When you wake up every morning, the first thing you do is "nausea and vomiting", not only can you not eat anything, but even smell certain tastes and want to vomit.
The day before yesterday, the little niece couldn't help but send a circle of friends to complain: "Every day I vomit in the dark, am I pregnant with a Nezha..."
Someone at the bottom commented comfortingly, saying conclusively: "This is a good thing! Studies have proved that the more you vomit during pregnancy, the smarter your baby is! ”
In real life, I believe that many people have heard similar statements, especially some elderly people of the previous generation, and they are even more convinced of this.
However, will the morning sickness reaction be related to the child's IQ? Sounds really unreliable.
So in the spirit of "bold assumptions, careful verification" attitude, I consulted a lot of information, and found some relevant research, the answer may not be the same as some people's expectations.
Studies have shown: the more severe the morning sickness, the smarter the child?
There was a study done by researchers in Canada, they followed up 121 pairs of mothers and children, group control, observation experiments.
In the study, the 121 moms were divided into 3 groups, of which:
Group 1: 45, with a morning sickness reaction, and taking some kind of drug to treat the morning sickness reaction;
Group 2: 47, with morning sickness reactions, but did not take related drugs;
Group 3: 29 bits, no morning sickness reaction.
By the time the mom's children reached the age of 3-7, the researchers gave them detailed tests, including IQ, behavioral assessments, and more.
The results showed that children with mothers with morning sickness reactions performed better than children without mothers without morning sickness reactions in terms of IQ, language fluency, phonological processing, numerical memory and other aspects when they grew up.
And the researchers also mentioned that the severity of the morning sickness reaction was directly proportional to the children's test results.
In other words, the results of the study confirm that morning sickness is not only related to a child's IQ, but that the more severe morning sickness, the smarter the child is, and that the correct statement is that "the more severe the morning sickness, the smarter the child."
Seeing this, it is estimated that many mothers who have been tortured by morning sickness reactions or are in the process of morning sickness have been "happy on the eyebrows" and have received some psychological comfort.
However, this research is actually not too reliable, not only there are many "hard injuries", but also has not been widely recognized by the medical community.
Why are the findings unreliable?
First, the study's design itself has limitations.
During the study, the Canadian anti-morning sickness prescription drug "Diclectin" was used, which could not reflect the real morning sickness phenomenon, so it was questioned a lot.
Second, the study's data sample is too small to be representative.
The researchers selected only more than 100 samples, all Canadian, and the study was small and could only be used as a small, observational study, and the conclusions were not very credible.
So in summary, with such a small observational study alone, we cannot think that the more severe the morning sickness reaction, the smarter the child.
In fact, logically speaking, the reason why there is such a statement may be to give psychological comfort to the mother who is in the process of morning sickness, and to talk about comfort.
On the other hand, it may be because of the "survivor bias", the mother who has a serious morning sickness reaction pays more attention to the child's intelligence, and when the child is indeed better, it invisibly verifies this statement, which is only a "coincidence" in the final analysis.
These factors really affect a child's intelligence
1. Genetic factors
The level of a child's intelligence is very closely related to genetic inheritance.
Relevant studies have proved that people with an IQ of more than 140 points generally have an IQ of more than 128 points, while the probability of children with low IQ problems is as high as 59%.
In real life, it is not difficult to find that there are countless similar examples, such as Gu Ailing, the "genius girl" who was on fire some time ago, many elders have graduated from famous schools such as Peking University and Stanford, and then such as the musician Bach, most of his family has achieved good achievements in music.
2. Environmental factors
In addition to genetic factors, the growing environment also has a great influence on children's intelligence.
In the process of children's growth, if they do not receive a good family education, or the family environment is unstable, it will directly affect their intellectual development.
On the contrary, if parents attach great importance to their children's education, they can create a more positive growth environment, which is of great benefit to improving their children's intelligence.
3. Nutritional intake during pregnancy
The development of the fetus can directly determine whether the child is smart or not, so the nutritional intake of the expectant mother during pregnancy is crucial.
During pregnancy, expectant mothers should try to achieve a balanced diet, eat less and more meals, ensure adequate nutritional intake, and develop healthy eating habits.
4. Breastfeeding
Breast milk contains a large number of long-chain saturated fatty acids that can promote the development of the baby's IQ, and a 30-year follow-up report in Brazil shows that breastfeeding people have higher IQs and better incomes and academic qualifications.
Therefore, if conditions permit, we should still try to insist on breastfeeding as much as possible to promote the intellectual development of the baby.
Old Miao Conclusion:
The statement that "the more severe the morning sickness reaction, the smarter the baby" is completely nonsense and has no scientific basis.
If we want to promote the intellectual development of children, we still have to start from some acquired factors to really have a definite effect.
