Baby weight at birth indicates future IQ, is there a scientific basis?

My cousin gave birth to a fat boy weighing 8.6 pounds for the second time. Her mother-in-law was so happy that she always praised her daughter-in-law for her great achievements this time. Her grandson weighed 8.6 pounds. When he was born, he looked more energetic than the baby next door. You will definitely be smart in the future. Suddenly I discovered that the older generation is obsessed with the birth weight of their children. I don’t know if I will be smart or not in the future, but I can’t bear to look at my cousin who looks haggard. Why bother? Although the fat boy weighing 8.6 pounds sounds good, only he knows what his mother suffered. Babies who do not increase in standard weight or grow slowly are mostly troubled by these four reasons. During pregnancy, my cousin once said that my mother-in-law was obsessed with big fat boys and big fat girls. I tried every means to supplement her nutrition every day. Every time I had a prenatal check-up, the baby was too big. Although the doctor asked me to control her weight, it was obvious that my mother-in-law didn\’t think it was necessary. Because in the mother-in-law\’s mind, fat boys and girls represent high IQs, and she cannot let her grandsons and granddaughters lose at the starting line as soon as they are born. Does the big fat boy have a high IQ? Many elderly people around Fei Ye are like my cousin\’s mother-in-law. They like fat boys and girls. Based on experience, they believe that such children are not only easy to raise, but also smart. But is this really the case? Not necessarily. Many experts have conducted relevant research on \”weight\” and \”IQ\”. The most famous of these is a joint tracking study by Columbia University and New York Medical College. They counted the weight of 3,500 newborns and tracked them for decades, measuring each step in stages. A child’s IQ level. Finally, it was discovered that newborn weight is not directly proportional to IQ. Overweight and underweight babies have lower intelligence levels than their peers. John Medina, an authoritative neuroscientist in the United States, has also done this kind of research. He found that there is a certain relationship between a baby\’s IQ and weight. The intelligence level of babies about 6-7 pounds is higher than that of children with other weights. After exceeding a certain weight, brain development will be affected and intelligence will decline. In other words, fat boys and girls do not have an advantage in intelligence. On the contrary, they increase the difficulty of childbirth and cause greater harm to the mother. This is why doctors always ask pregnant women to control their weight during prenatal check-ups. I would like to sincerely advise you that there is no need to be obsessed with your child’s birth weight. If you have a baby, don’t worry about it growing. If you jump ahead of the baby, it will affect your baby’s health. Optimum weight for newborns. Weight is one of the important indicators for measuring a child\’s development during pregnancy and reflects the child\’s health to a certain extent. Being underweight or overweight is not conducive to a child\’s development. Generally speaking, a child\’s birth weight is most suitable between 6 and 7 pounds. Newborns weighing less than 5 pounds are called \”low-weight infants.\” These children are generally thin and have relatively slow development of various physiological functions. Relatively speaking, brain development will be slower than that of peers, with a 15% probability of affecting their IQ development. The low birth weight of newborns indicates that they did not receive enough nutrients during the fetal period, and their physiological functions may be much weaker than those of other babies. This may result in poor development of the child\’s metabolic system. Therefore, more attention must be paid to the care of such children. Do not feed them like crazy in order to make the child reach the target weight after birth. This will have the opposite effect.It can cause gastrointestinal discomfort in children. Of course, if the child is 3 or 4 years old and has always been thin, parents are advised to take the child to the hospital for relevant examinations to avoid delaying the child\’s development. Newborns weighing more than 8 kilograms are called \”macrosomia.\” Research clearly points out that the IQ of macrosomic babies weighing more than 8 kilograms will be affected. This is because the nutrition of the fetus during pregnancy comes from the mother\’s body, and the more adequate nutrition the child has, the better. The development will be better, but the fetus does not need to breathe on its own in the mother\’s body. In other words, the fetus has many fewer organs that operate autonomously in the mother\’s body than after birth. Once a child is born, various physiological functions will start to operate automatically. At this time, difficulty breathing is a serious problem for macrosomia. Poor breathing can easily lead to insufficient brain supply, which can easily lead to impaired brain development and mental retardation. This is why the proportion of cerebral palsy among macrosomia infants is much higher than that of ordinary infants. The neighbor\’s little chubby boy weighed 8.2 pounds when he was born. Now he is only 5 years old and already weighs 70 pounds. He did not meet the standards in the kindergarten physical fitness test. The nutritionist earnestly advised his parents to help him lose weight, and warned that if he continued, he would be at great risk of obesity, hypertension, and diabetes. You see, the direct result of a fat boy may be a fat boy with an impact on intelligence. Therefore, if you want to give birth to a smart baby, you must control your weight during pregnancy. It is recommended to try to ensure that the monthly weight gain does not exceed 2 kilograms in the first trimester, and the total weight gain during the entire pregnancy does not exceed 15 kilograms. Mothers must properly control their weight during pregnancy. The development of a child during pregnancy comes from the mother. In order to ensure that the child is born at an appropriate weight, mothers must pay attention to weight control during pregnancy. Scientific diet during pregnancy: Energy: Energy intake during pregnancy should be increased by 200kcal per day compared with non-pregnancy. Energy is very important for the developing fetus. Protein: A full-term fetus contains 400g of protein. The Chinese Nutrition Society recommends that the recommended protein intake for pregnant women is to increase by 5g, 15g and 20g in the first, second and third trimesters respectively. High-quality protein accounts for at least 1/3 of the total protein. Fat: Lipids are an important part of the fetal nervous system. Pregnant women need to store 2~4kg of fat during pregnancy. The fat stored by the fetus can be 5%~15% of its body weight. The Chinese Nutrition Society recommends that the energy supply ratio of dietary fat during pregnancy is 20% to 30%. Generally speaking, in early pregnancy, you should choose foods that are light, easy to digest, and increase appetite; eat small meals frequently to ensure normal food intake; early pregnancy reactions are most obvious in the morning and after meals. You can eat something low in water and carbohydrates before getting up. Rich food. The second and third trimester of pregnancy are stages of rapid fetal growth and brain development. The mother herself also begins to store fat, protein, etc., and at the same time, calcium and iron deficiency increase. From the 4th month of pregnancy, pregnancy reactions begin to disappear or reduce, and appetite improves. It is necessary to increase energy and various nutrients to achieve a comprehensive and diverse diet with meat and vegetables. Reasonable exercise and proper prenatal education. Many mothers will become lazy during pregnancy and either sit or lie down. However, this is actually not healthy for the development of the child. We recommend that pregnant mothers should ensure half an hour of exercise every day. Don\’t underestimate this half hour, it canLet the brain secrete dopamine to excite the body. The excitement of the mother\’s body will also make the child feel the joy of exercise, thereby promoting the fetus to better absorb nutrients from the body. In addition, proper prenatal education can make the child\’s sense of the world clearer after birth. We all know that the senses are the basis for children to increase their cognition. The richer the senses, the more stimulation to the brain, and the more perfect the brain development will naturally be. Finally, I would like to say that the weight of the fetus is not only related to the child\’s intelligence, but also directly affects the difficulty of the mother\’s delivery. There is no need for pregnant mothers to give birth to a fat baby. The key is to eat a reasonable diet and follow the doctor\’s advice.
