Puberty is driven by the activity of sex hormones and its onset is announced by the appearance of pubic hair, beards and breasts. For boys and girls this growth spurt generally happens at different ages. And there can be big differences as to when the growth spurt happens.

For girls, rapid growth generally occurs around age eleven and a half years but can begin as early as eight or as late as 14 while for boys it generally happens a year or two later than girls.

Children continue to get taller during their growth spurt until the ends of their long bones fuse and stop increasing in length, which happens around the end of puberty. And our new findings published in JAMA Network Open suggest that teens who have their pubertal growth spurt later could have more problems with their bone health in the future.

Our study is not the first to report a link between the timing of puberty and bone strength. A study of British people born in showed that children who had their growth spurt at an older age had lower bone density near the end of their forearm bone when measured decades later in old age, making them more likely to get a broken wrist.

More recently, a study of adolescents and young adults from Philadelphia showed that people who were genetically predisposed to later puberty had lower bone density at the spine and hips sites which are known to be susceptible to osteoporosis in later life. Overuse injuries also called repetitive stress injuries can affect the growth plate in kids and teens.

Overuse injuries happens from repeating the same movement over and over. They usually happen to people who play sports. Reviewed by: Amy W. Anzilotti, MD.
