It is necessary to measure height every month after treatment for both short stature and precocious puberty, and since the change in height within a month is small, it is necessary to measure it as accurately as possible. Accurate height measurement needs to pay attention to “four similarities”: ① the same time, because after standing or sitting up, the vertebral space of the human spine will be compressed, the height of the morning and evening will be different, the same time measurement to be comparable; ② the same measuring tape; ③ the same measurer to measure the person, different people, the ruler card in the head of the tightness will be different; ④ the child The same method of standing (requiring shoes off, heels, hips, shoulders and head all against the wall, chest up, stomach in, waist as straight as possible, eyes level, head not too tilted, otherwise the highest point of the head can not be measured). If you measure at home, you can put a piece of paper on the wall, and draw a line on the paper after each measurement. It is not necessary to draw a specific height for each measurement, but only to distinguish the difference with the previous month. When measuring at home must pay attention to the ruler and the floor level, you need to use a right angle triangle ruler, or use a hard book, one side against the wall, the other side and the floor level. From time to time, parents will respond, “My child grew by 2cm last month, but why did he not grow at all this month?” The main reason is that it is still related to the measurement error. After a longer treatment time, the growth rate of several months can be averaged (Note: usually do not measure height too often, generally once a month, otherwise it is easy to cause psychological pressure on the child, too much psychological pressure is not conducive to growth).
