How many pounds does your baby weigh when he is born?
In many parts of the mainland, there is a saying that "the heavier the baby is born, the smarter it is", and even some mothers will "eat a lot" during pregnancy, just to have a "fat son".
In fact, the reason for this statement is due to the special background of the times.
In the era of material poverty, even pregnant women, it is difficult to get adequate nutritional supplements, so many children will be born malnutrition, while those families with relatively good economic conditions, because nutrition "can keep up", so children look better developed, weight is higher, giving people a healthier, smarter.
In modern society, people's living standards have made great progress, and the saying that "the heavier the baby is born, the smarter it is" is undoubtedly outdated.
Of course, newborn weight is not unrelated to IQ, from a scientific point of view, there is indeed an "optimal weight" when the baby is born, and the baby who meets the "best weight" is likely to be smarter.
How much weight is the best for newborns? The relationship between your baby's intelligence and birth weight
Dr Richards, the British Medical Research Association, conducted a study in which he and his assistants followed up 3900 people born in 1946 over a long period of time, and the results showed that, within a certain range, newborn weight was positively correlated with intelligence.
At first glance, this seems to coincide with the saying circulating on the mainland, but in fact, the weight of newborns is not as heavy as possible, the key lies in "a certain range".
Researchers have found that newborns are best kept within 2.5-4.2 kilograms, and once they exceed or lack this range, the baby's cognitive ability will be affected.
To this end, the researchers speculate that in a sense, newborn weight can represent the state of brain development, and heavier babies receive more nutrients before birth, when they are in a critical period of brain development, so their intelligence is more fully developed.
Once the baby weighs more than 9.3 pounds (4.2 kg) at birth, it will be medically recognized as a giant child, and too much fat appears in the brain, hindering the development of nerve cells and the regeneration of nerve fibers, but affecting intellectual development.
If the baby is born with too low weight, it may not be fully developed in the brain, and there will be a certain gap with peers in the early stage, but in general, if the acquired can be scientifically fed and strictly nursed, intellectual development can generally catch up.
In summary, the optimal weight of newborns should be in the range of 2.5-4.2 kg, close to about 7 pounds is better, too low or too high is not conducive to the baby's IQ development.
What are the factors that affect newborn weight?
1. Age of birth
Newborn weight increases with maternal age in newborns under 30 years of age, and decreases with age over 30 years.
2. Gestational age
When the gestational age is too short, the baby is born prematurely, the body is not fully developed, and the weight will be lighter. When the gestational age is more than 44 weeks, the baby's weight will also decrease over time.
3. Nutritional status during pregnancy
Expectant mothers dieting, partial eating, picky eating, will not be able to ingest adequate nutrition, resulting in light fetal weight, on the contrary, if the expectant mother's pregnancy meal big fish and meat, do not know moderation, will increase the weight of the fetus too much, it is easier to give birth to "giant children".
4. The health of the expectant mother
If the mother-to-be is in poor health, such as high blood pressure, heart disease, kidney disease and other diseases, it will also make the newborn weigh less.
How to control your weight during pregnancy and give birth to a healthier baby?
If the weight of the baby to be born is within the normal range, the mother should learn to control the weight during pregnancy and do a good job of weight management.
In general, we should use the pre-pregnancy body type and physique base (BMI) as the standard to determine whether the rate of weight gain during pregnancy is "excessive".
The so-called physique base refers to the result obtained by dividing the weight (kg) by the square of height (m), less than 18 is a thin type, between 18-24 is a standard type, more than 24 is too heavy, and greater than 27 is an obese type.
And the weight we gain during pregnancy is:
The BMI before pregnancy is less than 18, and the weight gain ranges from 12.5--18Kg;
The BMI before pregnancy is 18-24, and the weight gain ranges from 11.5 to 16 Kg;
The BMI before pregnancy is greater than 24, and the weight gain ranges from 7 to 11.5 Kg.
It is worth mentioning that the weight gain throughout pregnancy is not linear, the first half of pregnancy is about one-third, the second half of the growth is two-thirds, and the 7th month is the fastest growth period.
When we find that our weight gain is too fast or too slow, we must learn to properly control the diet, develop healthy eating habits, try to eat less and eat more meals, and exercise appropriately.
For example, walking, swimming, yoga, etc., are very suitable for pregnant women's exercises, not only to help control the body shape, but also to enhance physical fitness, help to give birth.
Old Miao Conclusion:
Newborn weight is a key indicator of the baby's health index, generally within 2.5-4 kg, are considered normal weight newborns.
In order for the baby's weight at birth to reach a more ideal value, expectant mothers must consciously do a good job of weight management during pregnancy, after all, it is most important to give birth to a healthy baby.
