Research Interests: 

Reduced bone mineral density leads to osteoporosis, resulting in bones becoming increasingly brittle and at risk for fracture. With the cost of treatment in 2010 estimated at $10 billion, osteoporosis is a significant public health issue that affects 55 percent of Americans age 50 and older. The 2000 National Institutes of Health Consensus Development Conference on Osteoporosis Prevention, Diagnosis, and Therapy identified bone mineral deposition during adolescence as a critical determinant of osteoporosis risk later in life. The care of patients with osteoporosis is difficult, and most therapies increase bone density by small amounts, yet require long periods of treatment. In contrast, during puberty large increases in bone density occur over a short period of time.

Puberty is a time of significant bone development and during this time, bones grow and increase in density. At the end of puberty, the epiphyseal plates close, terminating the ability of the bones to lengthen. When that occurs, the teenager has reached his or her maximum height and, soon after, peak bone mass. By employing sensitive instruments for measuring bone mass at the beginning of puberty, Gilsanz and his colleagues can extrapolate what a teenager’s peak bone mass will be at the end of puberty. Using this information, they can potentially identify adolescents at risk for decreased bone density at the beginning of puberty, when there is still time to intervene and take advantage of the tremendous deposition of bone that occurs before puberty ends.
