[Henan Science Popularization] "Dietary Guide" easy to read: How to pay attention to the development of school -age children's physical development?(superior)

The height and weight of school -age children can reflect the level of physical development, mainly through three stages:

Relatively stable period: Before adolescence development, height and weight growth continued to stabilize. Children's height increased by 5-7 cm per year, and weight increased by 2 to 3 kg;

Growth and increase period: It is one of the main performances of adolescence. When entering the peak of an increase, it can increase by 10 to 14 cm in height, and it can increase by 8 to 10 kg a year;

Growth stagnation period: Since the middle and late period of youth, height and weight generally stop growing significantly.

At the same time, with the development of adolescence and changes in body shape, parents need to pay enough attention.

1. Monitor the height and weight regularly

Regularly measure height and weight, and can timely understand the dynamic changes of the physical development level of school -age children. School -age children should self -test at least once a week, and self -test height once a quarter.

The school should conduct at least one height, weight measurement and sexual development test for school -age children. For slow growth and sexual development, early and backwardness, malnutrition or obesity children, the frequency of measurement should be added, once every 3 to 6 months, if necessary, bone age testing and other clinical examinations in order to discover problems in time and symptomatic treatment.

Nutrition refers to insufficient energy and/or nutritional intake, excess or imbalance. Nutrition includes insufficient nutrition, such as dysplasia -low height, low height, weight loss, low weight, lack of weight -low weight, also include trace nutrient deficiency or insufficient, such as lack of important vitamins and vitamins and vitamins and vitamins and Minerals, as well as non -ductive diseases related to overweight, obesity and diet, such as heart disease, stroke, diabetes and cancer.

2. Correct understanding and evaluation of the body

Suitable height and weight growth are the embodiment of the nutritional balance of school -age children. It should establish a scientific outlook on health, correctly understand the body shape, and ensure that the appropriate weight growth is guaranteed.

Some adolescent girls are pursuing a slim body and excessive diet can cause metabolism disorders of the body, and even severe death. Parents and schools should advocate a scientific outlook on health, strengthen guidance for adolescent girls, establish a correct body type cognition, and adapt to adolescent changes.

Based on my country's health industry standards "School-age Children and adolescents' malnutrition screening" (WS/T 456-2014) judge children's malnutrition. First adopt the height combining age to determine whether it is a slow growth. In addition to the slow growth of growth, then use the BMI boundary range to make a weight loss judgment.

BMI is used as a first screen indicator for general obesity. According to my country's health industry standards "Overweight and Obesity Screening" (WS/T 586-2018), children's superb obesity is judged. The auxiliary screening of waist circumference as the central obesity, according to my country's health industry standard "7-18-year-old children and adolescent high-waist screening circles" (WS/T 611-2018) to determine the child centered obesity.
