Growth monitoring is the repeated measurement of height and weight for the same child at a specific age over a certain period of time. The height and weight values measured at one time reflect the level of growth achieved at the age at which the measurements were taken. However, in clinical practice physicians also need to know the growth rate of a child over a certain period of time, because the growth rate of a child is the most direct and easiest effective method to determine all growth disorders. By measuring height continuously over different periods of time, it is possible to calculate the rate of growth in height, so that acceleration or retardation can be evident and the factors affecting growth can be exposed. Children with normal growth rates can indicate that their growth is currently normal, but it is not possible to determine whether future growth will be normal. Children with abnormal growth rates can be interpreted as growing poorly, regardless of their current height. The easiest way to determine if growth rates are normal is to record data measured at different age intervals and trace them on a growth curve chart. If the child’s own curve rises parallel along one of these lines, it indicates normal growth. If the curve flattens or declines, something is wrong with growth. Children over 3 years of age are considered to be stunted if their height growth is estimated numerically to be less than 4 cm per year. For children with puberty, a combination of indicators such as the degree of sexual development and bone age is also needed. Children should have their height and weight accurately measured at least once a year, and carefully recorded and kept. Because these figures record the footprints of children’s growth and reflect the growth and health status at different ages, they are more valuable than general laboratory results. Therefore, as a caring and loving parent, you should regularly give your child a physical examination, record the measurements at different times, and trace them on a simple growth curve. The child’s own growth curve is obtained by connecting the points traced several times. If the child’s curve follows a consistent line, it is healthy. Conversely, if the curve suddenly moves from one grade to a lower grade, watch for adverse factors that are interfering with the child’s growth.
