Growth monitoring involves measuring the height and weight of the same child several times at regular intervals. This is because the height and weight values measured at one time only reflect the level of growth achieved at the age at which the measurements were taken. The most direct and easy way to determine the growth disorder of a child is the growth rate of the child over a certain period of time. By continuously measuring height at different points in time within a certain period of time, one can calculate the growth rate of height. Through this indicator, it is easy to determine whether the increase in height of a child is accelerated or retarded, so that the causes affecting the growth of the child can be found in time. If the growth rate is normal, it means that the current growth is normal; while for children with a slowed growth rate, it can be explained as poor growth regardless of their current height. The easiest way to determine if height growth rates are normal is to record height data measured at different time points in age and trace them on a growth curve chart. If the child’s own curve rises parallel to one of these lines, the growth rate is normal. If the curve flattens or declines, something is wrong with growth. A child over the age of 3 years is considered to have a growth retardation if the growth rate is estimated numerically to be less than 5 cm per year. For adolescent children, this can be combined with the degree of sexual development, bone age and other indicators. It is recommended that caring parents measure their child’s height and weight accurately every 3-4 months, or at least once a year, and carefully record and store the measurements and the time of measurement (to the exact month and year). It is a good idea to also record the measurements on a growth chart. The child’s own growth curve is obtained by connecting the points traced several times. By comparing the child’s own growth curve with the standard curve of a normal child population, it is easy to visually determine whether the child’s height is normal. If the child’s curve continues along a grade line, it is healthy and normal. If the curve suddenly moves from one level to a lower level, it suggests that there are adverse factors interfering with the child’s growth.
