What are the height and weight standards for normal children and girls? What are the main factors that affect the height and weight of normal children and girls?

With the change of concepts, many parents have begun to pay attention to the health of girls and hope that they can maintain normal height and weight. The normal height and weight of girls will be different at different ages, because there are many factors that affect girls to maintain normal height and weight. In addition to common genetic factors, nutritional factors, living environment, etc. will affect the development of girls' height and weight, which are factors that cannot be ignored.

Height and weight are the most important things that every parent cares about, because the height and weight of children, especially girls, will affect their normal life in the future. With the improvement of living standards and the nutrition and diversification of food, the height and weight of girls have increased significantly. However, some parents have only a vague understanding of the normal height and weight range for girls. So, what is the normal height and weight of girls?

1. Normal height and weight of girls

The height and weight of normal girls vary according to their age. Generally speaking, the normal height is: age multiplied by 2 plus 7 or 8, which is the standard height of girls. As long as the normal height is close to this standard error of about 2 to 3 centimeters, it is normal. The standard for girls' weight is: height (cm) minus 105. The numerical error greater than or less than 10% is within the normal range.

2. The main factors affecting the height and weight of normal children and girls

1. Genetic factors

The height, physical strength and development of girls are greatly affected by genetic factors. If the parents are tall, strong and healthy, the growth and development of girls will have a good foundation. If the parents are physically weak and have genetic diseases, the growth of girls is more likely to be negatively affected.

However, genetic factors are not unchangeable. For example, through exercise, attention to nutrition and enhanced disease prevention, the original genetic basis can be improved and enhanced so that children can grow and develop normally.

2. Nutritional factors

Nutrition has a great impact on physical development, especially weight and height, and the younger the age, the greater the impact. Because girls grow and develop quickly during childhood, the quality of food they need is higher than that of adults. Nutritional factors mainly refer to the adequate supply and reasonable intake of nutrients.

3. Living environment

Girls should live in a good environment with fresh air and plenty of sunshine. Combined with exercise and nutrition, they will grow faster. In the four seasons of the year, weight growth is generally faster in autumn and height growth is faster in spring.
