Describe the sex differences in body growth
What will be an ideal response?
Answer: In infancy, girls are slightly shorter and lighter than boys, with a higher ratio of fat to muscle. These small sex differences persist throughout early and middle childhood and are greatly magnified at adolescence. But body size is not enough to tell us how quickly a child's physical growth is moving along. The best estimate of a child's physical maturity is skeletal age, a measure of bone development. When skeletal ages are examined, girls are considerably ahead of boys. At birth, the sexes differ by about 4 to 6 weeks, a gap that widens over infancy and childhood. Girls are advanced in development of other organs as well. This greater physical maturity may contribute to girls' greater resistance to harmful environmental influences.
