What is the height and weight standard for a four-year-old girl?

The physical development of children is something that parents are very concerned about. As children grow up day by day, their height and weight also change greatly. If the child grows older but the height and weight do not increase, our parents will be very worried at this time, worrying that such a phenomenon in the child's body is an abnormal condition. So what is the standard height and weight of a four-year-old girl?

Developmental Standards:

1. Height The occurrence of a height growth spurt is a sign that boys and girls are entering puberty. The height of adolescent boys can increase by 7-9cm per year, up to 10-12cm, and an average increase of 28cm during the entire puberty; the height of adolescent girls can increase by 5-7cm per year, up to 9-10cm, and an average increase of 25cm during the entire puberty. Because boys begin puberty later than girls, their bones stop growing later. In addition, boys' growth spurt is larger and lasts longer, so by adulthood the average height of men is generally about 10 cm taller than that of women.

2. Weight is easily affected by environmental factors such as nutrition and disease, and its stability is less stable than height. It mainly reflects the changes in the quantity of bones, muscles, adipose tissue and internal organs, so it can continue to grow even after puberty. Body weight refers to the total weight of the body, including bones, muscles, fat, internal organs, etc. As girls age, their body fat continues to increase, with a peak in fat accumulation during puberty, when they mature, the amount is twice that of boys. As boys age, their muscles continue to develop, reaching their peak at age 30, and when mature, they are 1.5 times that of girls.

3. Lean body mass and body fat Lean body mass (lean body mass), also known as fat-free body mass, includes the bones, muscles, various internal organs, nerves, blood vessels, etc. of the whole body, also known as metabolically active tissue. Body fat refers to all the fat tissue in the body, but most of it is stored in the subcutaneous tissue, also known as metabolically inactive tissue. The sum of the two is the body's weight. It is a normal physiological phenomenon for girls to have a high body fat content, and there is no need for girls to worry too much about suffering from "obesity". Some girls aged 16-17 do not understand these physiological changes and lack the necessary health knowledge. They mistakenly believe that the thinner the better and are afraid of getting fat so they try their best to restrict their food intake, which leads to physiological dysfunction caused by morbid psychology, namely anorexia nervosa, which seriously affects the normal development of children and adolescents and should attract the attention of relevant departments. Due to the difference in lean body mass and body fat content between boys and girls, boys have a sturdy body shape with well-developed muscles, broader shoulders and larger chest circumference. Girls, on the other hand, develop a fuller body shape with a high body fat content, a wider pelvis, and narrower shoulders.

The standard for children's height and weight is just a range of values, which does not indicate any problem. If it exceeds or decreases but not seriously, then it does not matter. Every child develops differently, so the height and weight will not be the same at the same age. Children's development is inseparable from their diet, so remember to feed your children more nutritious food.
