Height and weight standard for nine and a half year old girls

Whether the child's height and weight are qualified has always been a concern for parents. Therefore, parents use the standard height and weight table for children aged 3-6 to consider the growth and development of school-age children. However, how should the height and weight standards for 9-year-old children be considered?

Height and weight standards for 9-year-old children

Based on the survey report on the physical growth and development of children and adolescents, the Department of Women and Social Affairs of the Ministry of Health of China organized relevant authoritative experts to scientifically research and formulate the "Reference Standard for Growth and Development of Children Under 7 Years Old in China", which was announced and released by the Ministry of Health on June 2, 2009. The growth and development of boys and girls are different. Parents can refer to the data in the following table to see if their children's height and weight are normal. It should be noted that the height and weight standards for children aged 3-6 are not absolute standards. As long as the child's height and weight are within the normal range and there are no abnormal symptoms in the body, parents do not need to worry too much.

Height and weight are important indicators for judging whether a child's growth is normal. The following is a detailed introduction to the calculation method of normal height and standard weight of children:

The accurate measurement formula for infant standard weight is as follows:

1-6 months weight (Kg) = birth weight (or 3Kg) 1-6 months weight 0.6 (Kg)

7-12 month weight (Kg) = birth weight (or 3Kg) 1 month old baby 0.5 (Kg)

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

The growth regularity of infant height standards:

The average body length 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 about 5 cm on average each year, so the body length (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.

The weight of a 9-year-old girl is 24.1-35.3 kg and the height is 125.7-138.7 cm; the weight of a boy is 24.3-34.5 kg and the height is 126.5-137.8 cm.

The method to predict the baby's future height: the boy's adult height (cm) = (father's height x mother's height) + 1.11 (1.12) / 2, the girl's adult height (cm) = (father's height + 0.948 (0.980) mother's height) / 2. This formula basically conforms to the rule that tall people grow taller and short people grow taller. There may be certain differences depending on the different situations of the children, so it is for reference only.

For example: the father is 170cm tall and the mother is 160cm tall, then the minimum height of the baby girl in the future is (170*0.948 160)/2, and the maximum height is (170*0.98 160)/2.
