Grow too fast

Introduction The so-called babies grow too fast to supplement the nutrition of infants born in full-term, which can lead to excessive growth and increase the risk of cardiovascular disease in adulthood. In the neonatal period, there is a significant increase in physical development, and there are features such as long head giant brain, mental retardation, specific face and abnormal limb shape. The birth weight and length of the child are larger than normal, and the growth is rapid within 4 to 5 years after birth, and then the growth seems to be close to normal and stable, but the measured value is still more than two standard deviations from the same age average. Infants do not grow as fast as possible, and slower growth is beneficial to future health.

Cause

Early infant nutrition has a planning effect that affects future cardiovascular risk factors, cognitive ability, and bone health. There is a paradox in this group: high levels of nutrition and growth in infants are good for brain development, but increase the risk of cardiovascular disease in the future; slower growth levels are good for cardiovascular health. The incidence of men is higher than that of women (4:1 or 3:1), so it is usually considered as X-linked inheritance. May be caused by pathological factors in the uterus, or damage to the function of the hypothalamic-pituitary axis.

In China, we have established reference standards for infants and young children's growth and development. Parents can also make a rough estimate based on the following general rules for the growth of children: in terms of weight, the baby will increase by 0.6 kg per month in the first half of the year and 0.5 kg in the second half of the year. For example, a baby weighing 3 kg at birth; 6 to 7 kg at 6 months, about 2 times at birth; at the age of one, 9 to 10 kg, about 3 times at birth; at 2 years old Increased to 4 times at birth, about 12 kg. After the age of two, the average annual increase is about 2 kg. From the length of the body, it will increase by 2.5 centimeters per month in the first half of the year and 2.5 centimeters per month in the second half of the year. For example, a child is usually 50 cm at birth, and should be increased to about 75 cm at the age of one and about 85 cm at the age of two. After two years of age, the average annual increase is about 5 cm.

If you want to accurately observe the child's growth and development, in addition to understanding the child's length and weight, but also to evaluate the child's operation, language and other development, in short, participating in child care is the most ideal way.

Differential diagnosis

Should be differentiated from giant infants, infant obesity, etc.

Giant infants may cause the mother's blood sugar level to be too high and the excessive weight to increase and cause the fetus to be huge.

Infant obesity is overnutrition and environmental factors. Most fat children have an appetite, do not eat, eat fast, love sweets, like snacks, daily intake of heat in the body exceeds consumption, it is converted into fat accumulation in the body.
