The growth characteristics of children

Whether boy or girl, regardless of the speed of growth is faster or slower, growth and development in various stages of growth in all parts of the body's ratio of more or less similar to the procedures are basically the same, but there are two noteworthy features.

First, the characteristics of the head and tail. In early childhood. The fetus has a large head (or body 4 / 8), a longer torso (3 / 8), short legs (1 / 8), to the development of 6-year-old when the ratio is more symmetry. Growth rate from the point of view, from pregnancy to birth, the head of the fastest growth, at birth to reach the adult head circumference of about 65%; from birth to 1-year-old, the trunk of the fastest growth, an increase of 0 to 6-year-old reached during the total 60 %; From the 2-year-old to 6 years old, lower limbs to speed up growth, much higher than the head and torso. This shows, children's development as early as the head of the trunk, limbs, trunk earlier than it. So that children get priority to the development of the nervous system the opportunity to promote their own movement, language, mental development and a variety of physical activities of the body is useful.

Second, to the characteristics of the heart. Mainly in the adolescent growth spurt, public health departments to start with the sudden increase in the order is far from the last of. The first foot sudden increase, the first stop growing. Enough to the sudden increase in the 6 months after the beginning of the sudden increase in the leg, thigh and then. Leg after the peak growth of 4 months, pelvis, chest followed by the beginning of the sudden increase in the width, 11 months after the beginning of the sudden increase in the shoulder width, height from the trunk of youth began in the late growth, chest wall thickness of the final turn. As early as in the lower limbs due to growth in the trunk, so young boys and girls in the mid-long legs once the long arm of the head of such a small body of non-conforming. The sudden increase in upper adolescence has to follow the basic characteristics of the heart, but appear a little later than age. Generally occur after the sudden increase in the thigh, before the sudden increase in the pelvis. With the sudden increase in order for the hand-forearm → → upper arm. Osteophiphysis hands of the order is basically from near and far, the order for the phalanx of-the-art → finger, the proximal metacarpal → → radius, the distal ulna.

More than familiar with the characteristics of adolescent health guidance on the provision of great significance. To know that the sudden increase is enough to mean that adolescent growth spurt is about to begin. Parents should give children as soon as possible to provide a wealth of calories, protein diet to meet the rapidly when the body's nutritional needs. And let the kids wear shoes more generous, more for running, jumping, and other physical activity. In various parts of the body during the sudden increase in demand for these neglected, will bring irreparable loss.
