The above is the specific content of the Standard Height Comparison Table for All Age Groups. Of course, the height of each child is different. It can't be said that a child's height does not meet the standard, so it is considered that the child is unhealthy. Because height is also related to many reasons, including congenital factors and acquired factors. Many parents may not know whether their children are normal in height, so how should they judge?
Scientific research has proved that 70% of the growth potential of height is determined by heredity, and the remaining 30% is influenced by acquired factors. At present, it is recognized that the more accurate formula for predicting children's height is: boy's height = [father's height+(mother's height+13)]/2 7.5, girl's height = [(father's height-13)+ mother's height ]/2 7.5.
Parents can budget their children's height in advance according to the above formula, and then see how far their children are from the standard height. In this way, parents can plan their children's physical exercise in advance, so that children can get exercise in sports, nutritional supplements and other aspects, and shape a healthy body.
