ADHD medications associated with diminished bone health in kids
Physicians should address risk, preventative strategies to avoid long-term consequences of low-bone density
American Academy of Orthopaedic Surgeons

Children and adolescents who take medication for attention-deficit hyperactivity disorder (ADHD) show decreased bone density, according to a large cross-sectional study presented today at the 2016 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS).

Dr. Rivera added that a definite link has not been established between osteopenia in childhood and osteoporosis later in life, which increases the risk of brittle and porous bones, and ultimately, fracture risk. However, low-bone density in children theoretically could have long-term implications and lead to poor bone health in adulthood because childhood and adolescence is when growing bones accrue mass and strength.

Medications used by patients in the study were: methylphenidate (Ritalin), dexmethylphenidate (Focalin), dextroamphetamine (Dexedrine), atomoxetine (Strattera) and lisdexamfetamine (Vyvanse). These medications can cause gastrointestinal problems such as decreased appetite and stomach upset, which may result in poor nutrition and reduced calcium intake. The drugs also may diminish bone density because they alter the sympathetic nervous system, which plays an important role in bone remodeling, or regeneration.

Dr. Rivera said that because most skeletal growth occurs by ages 18-20, physicians should realize the potential threat that ADHD medications pose to maturing bones and consider nutritional counseling and other preventative measures.
