What are the height prediction formulas?

The height prediction formula is as follows: (unit: cm)

Boy height =59.699+0.4 19× father height +0.265× mother height.

Girl's height =43.089+0.306× father's height +0.43 1× mother's height.

Predict the adult height according to parents' genetic factors. There are also several forecasting formulas. After comparison, the error of foreign formulas is relatively large. After investigating and counting the height of 182 1 young men and women and their parents 1983 ~ 84, Hubei Institute of Physical Education calculated the prediction formula of birth height, which has a smaller prediction error than that of foreign formulas, and has a good application effect in the selection of athletes and the evaluation of teenagers' physical fitness in China.

The future height predicted by bone age is mainly predicted from the current development level, and the future height predicted by parents' height is predicted from the innate genetic possibility, so the prediction results of the two are completely inconsistent.

It should be noted that because there are many factors affecting height, it is impossible to take all the factors into account in the prediction formula no matter which method is used, and many changing factors such as nutrition, disease and environment of the predicted object cannot be predicted after a certain period of prediction. Therefore, although we are sure that these forecasting methods are scientifically based, the trend reflected by the forecasting results cannot be wrong. However, the error of height prediction is always inevitable.

Methods and requirements for height measurement

1. measurement method: the measured person stands barefoot on the bottom plate of the altimeter in a "stand at attention" posture, and the heel, sacrum and scapula are close to the column of the altimeter. The surveyor can stand on the left or right side of the examinee, adjust his head to the level of the lowest point of the upper edge of the tragus and the lower edge of the orbit, and then move the horizontal plate of the altimeter to the top of the examinee's head with proper tightness, so as to measure the birth height.

2. Measurement requirements: Every time you measure your height, you should be barefoot, and at the same time (more accurately in the morning), you should use the same altimeter, and your body posture should be the same before and after. The altimeter should be placed on the flat ground, near the wall. It is best to measure the height twice continuously, with an interval of 30 seconds. The results of the two measurements should be roughly the same. The error of the height gauge shall not exceed 0.5 cm.

Methods and requirements for measuring upper body length

1. Measurement method: The measured person sits on the seat plate of the altimeter, and the pillow on the head, the ridge between the two shoulder blades and the sacrum should be attached to the column of the altimeter. When sitting, the head should be straight, the eyes should be straight, the trunk should be straight, the legs should be close together, the big legs should be kept at a 90-degree angle, the feet should be placed on the ground or the mat of the altimeter, and the arms should naturally fall to the side. The surveyor's position and operation are the same as height measurement.

2. Measurement requirements: The three points of the head to be measured, namely the occipital part, the ridge part between the two shoulder blades and the sacrum part, should be attached to the column of the altimeter. The rest are the same as height measurement.
