Adolescence: A Key Time for Building Bones

Moderate to vigorous physical activity is linked to adult bone health.

Adolescent bone health

Teens who stay fit with vigorous activity are laying the foundation for a lifetime of bone health. Study findings in JAMA Network Open  (2020; 3 [8], 2013463) show that teens who were moderately to vigorously active at ages 12–16 had higher bone mineral density in the hip bone at 25 than teens who participated in only light-intensity exercise. Peak bone mass occurs in young adulthood and is a risk marker of fractures and osteoporosis in later life.

University of Bristol researchers in England analyzed data from 2,569 young people who underwent accelerometer assessments at 12, 14, 16 and/or 25 years of age, followed up by four repeat assessments. Lead study author Ahmad Elhakeem, PhD, senior research associate in epidemiology, said, “The results highlight adolescence as a potentially important period for bone development . . . it is really important to support young people to remain active at this age.”
