The weight of the fetus is a critical factor in determining whether the pregnant mother can give birth smoothly. When a baby is born, the doctor weighs the baby  the baby scale. So the expectant mother is very concerned about the weight of the baby. What factors is the weight of the newborn related to?


Heredity

French and American researchers have recently found that the weight of a baby at birth is tied to the weight of both parents at birth. This indicates that there are likely genetic reasons for neonatal underweight.

The results of the survey found that if the mother was underweight at birth. The newborns are 4.7 times more likely to be underweight. If the father was born with a lack of weight, the newborns are 3.5 times more likely to be  underweight. If both parents were born underweight, the newborns are 16.3 times more likely to be underweight.4


·Situation of Pregnant Women

1.First birth age: The first birth age is under 30 years old, the birth weight of the newborn increases with the increase of the pregnant woman's age, and the birth weight of the newborn decreases with the increase of the age of the pregnant woman over the age of 31 years.

2.Gestational weeks: The fetal time in the mother is too short or too long, will influence the birth weight of the newborn. At 35 to 39 weeks of pregnancy, the birth weight of the newborn increased obviously in the increase of the week, 40 to 43 weeks of pregnancy, birth weight of the newborn gain is slow. After 44 weeks of pregnancy, the weight went down instead.

3.Health status of pregnant women: Pregnant women suffer from hypertension, heart disease, kidney disease and other diseases, neonatal birth weight is low. Infection with viruses or other microbes can also affect fetal development.

4.Pregnant women's hobby: Smoking in pregnant women can cause newborns to weigh less than normal weight.

5.Nutriture: Dieting, partial eating and picky eating of pregnant women can lead to nutritional deficiency and low neonatal weight.


·Fetal Factors

1.Parity and multiple fetuses: The birth weight of the second newborn is increased compared with the first one. The weight of multiple newborns is generally lower.

2.Sex of fetus: Female newborns is generally 110 grams lower than men.

Fetuses weighing about 3kg at birth have the best intellectual development. Many pregnant women need to be well treated. They eat more and do less. Excessive attention to nutrition during pregnancy but lack of exercise, resulting in excess nutrition of pregnant women is increasing. It is wrong to say that the faster the newborn is, the smarter it is. Overweight newborns are at increased risk of obesity in adulthood, and may be prone to metabolic diseases such as diabetes.Of course, there are many factors that affect people's intelligence, and birth weight is only one of them. Additional factors, such as small living space, serious air pollution and so on, can also affect people's intelligence.
