Factors affecting weight

1 Age at first birth: If the age of first birth is under 30 years old, the birth weight of the newborn increases with the age of the pregnant woman, but if the age is over 31 years old, it decreases with the age.

2 Gestational weeks: If the fetus stays in the mother's body for too short or too long, it will affect the birth weight of the newborn. From 35 to 39 weeks of pregnancy, the birth weight of the newborn increases significantly with each week; from 40 to 43 weeks of pregnancy, the weight gain is slower; after 44 weeks of pregnancy, the weight actually decreases.

3 Parity and multiple births: The birth weight of the second and fifth newborns increases compared to the first birth, and the birth weight of multiple births is generally lower.

4. Health status of pregnant women: Pregnant women suffer from high blood pressure, heart disease, kidney disease and other diseases, and the birth weight of newborns is low. Infection with viruses or other microorganisms can also affect the development of the fetus.

5. Pregnant women’s habits: Smoking during pregnancy can cause the birth of newborns to be lower than normal weight.

6. Fetal gender: Female newborns weigh 110 grams less than males.

The above is what the editor introduced to you about the normal height and weight range for babies. We also introduced some related factors that can affect the baby’s weight.
