Osteoporosis is a very important health problem for older adults. It is clear that bone mineral accrual during childhood is important in determining peak bone mass in young adulthood, which, in turn is critical for prevention of osteoporosis later in life as bone mass is lost.

In this issue of The Journal, Janz et al evaluate the longitudinal effects of physical activity on bone mass. They found that higher levels of daily physical activity were associated with greater whole body and trochanter bone mass in both boys and girls.

It should be clear that physical activity has numerous beneficial effects. Bone health is an important one. Pediatricians must advocate for more physical activity for children in school as well as at home.
