1, measuring height and weight: measuring the height of primary school students. Height should be measured in centimeters, preferably barefoot. You can make a mark on the wall to measure the height, or you can use a professional height measuring tool to measure it. The weight can be measured by weighing scale. In order to get an accurate weight, they should go barefoot and wear less clothes.
2. Calculate body mass index: Once you have the data of height and weight, you can calculate body mass index. The body mass index can be obtained by dividing the weight (kg) by the square of the height (m). For example, if a student weighs 25 kilograms and is 1.2 meters tall, then his body mass index is 25 divided by the square of 1.2, which is 25/ 1.44= 17.85.
Body mass index can be used to evaluate whether the weight of primary school students is healthy. According to different body mass index values, the weight of primary school students can be divided into three types: thin (body mass index is less than the fifth), normal (body mass index is between the fifth and the 85th), overweight or obese (body mass index is greater than the 85th). If your child's body mass index is abnormal, you should consult a doctor in time for a more comprehensive health assessment.
