Height and weight standard for 7-year-old children

A seven-year-old child is in a stage of growth and development. If he does not develop well at this stage, it will have a very bad impact on his height and weight in the future. However, many parents are not very clear about the specific weight and height standards for their children. Only after knowing the standards can they make improvements by comparing them. The effect of improving height and weight can be achieved through physical exercise and nutrient intake.

Age Weight (kg) Height (cm) Weight (kg) Height (cm)

6.0 years old 18.4-23.6 111.2-121.0 17.3-22.9

109.7-119.6

7.0 years old 20.2-26.5 116.6-126.8 19.1-26.0

115.1-126.2

8.0 years old 22.2-30.0 121.6-132.2 21.4-30.2

120.4-132.4

9.0 years old 24.3-34.0 126.5-137.8 24.1-35.3

125.7-138.7

10.0 years old 26.8-38.7 131.4-143.6 27.2-40.9

131.5-145.1

Standard measurement formula for infant weight:

Weight at 1-6 months (kg) = birth weight (or 3 kg) + age in months × 0.6 (kg)

Weight from 7 to 12 months (kg) = birth weight (or 3 kg) + age in months × 0.5 (kg)

2-10 years old weight (kg) = age × 2 + 7 (or 8)

Standard growth rules for infants and young children's height:

The average height of a full-term baby is 50 cm. It increases by about 25 cm in the first year after birth, so it is about 75 cm at one year old. Thereafter, it increases by an average of about 5 cm each year. Therefore, the height (cm) of a child aged 2-12 years old = age × 5 + 75 (cm). Anyone whose height exceeds the standard by 10% or is less than 10% is considered abnormal.

Factors that affect your baby's height

1. Nutrition

Stature is the sum of the head, spine and lower limbs. It is an important indicator of bone growth, especially long bone growth. When the baby's nutrition cannot meet the needs of bone growth, the rate of height growth will slow down. Nutrients closely related to bone growth include vitamin D, calcium and phosphorus. Insufficient iodine and zinc can also cause babies to be short.

2. Sleep

Growth hormone secreted by the pituitary gland is an important hormone that stimulates the baby's growth. The secretion of human growth hormone is unbalanced within 24 hours a day, and its secretion is higher during sleep than when awake. Lack of sleep will affect the baby's growth. Generally, newborns require 20 hours of sleep per day and night. From 2 to 6 months, it is 15 to 18 hours; from 6 to 18 months, it is 13 to 15 hours; from 18 months to 3 years old, it is 12 to 13 hours; from 3 to 7 years old, it is 11 to 12 hours. The amount of sleep a baby needs each day varies greatly from person to person. If some babies sleep less but their spirit, mood, and growth and development are normal, there is no need to force it.

3. Exercise

Exercise can promote blood circulation, improve bone nutrition, accelerate bone growth, make bones dense, and promote height growth. Babies under 3-4 months old should lie on their stomachs several times a day to promote whole-body activities, and should develop basic abilities such as turning over, crawling, standing, and walking as they grow older. Babies should not be held or sit for too long. It is not convenient for babies to move their whole body while being held, and sitting for a long time will affect the development of their lower limbs. At the same time, after babies learn to sit, they are often unwilling to learn to roll over and crawl.

4. Disease

Many diseases can affect the baby's height growth. Generally, acute diseases only affect weight, while chronic diseases can affect height. If, after long-term measurement and observation, the baby's height is always more than 10% lower than the average height of children of the same age, it is called growth retardation; if it is more than 30% lower, it is abnormal and should be diagnosed and treated in time.
