ADHD Meds Cause Bone Density Changes

A large cross-sectional study has found that children and adolescents who take medication for attention-deficit hyperactivity disorder (ADHD) show decreased bone density.

Researchers believe the finding should prompt physicians to address risk, and enact preventative strategies to avoid long-term consequences of low-bone density among children receiving medications for ADHD.

Study results were presented at the 2016 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS).

“This is an important step in understanding a medication class, that is used with increasing frequency, and its effect on children who are at a critical time for building their bones,” said senior study author Jessica Rivera, M.D., an orthopaedic surgeon with the U.S. Army Institute of Surgical Research.

The discovery is important as the U.S. Centers for Disease Control and Prevention (CDC) estimates 6.4 million children were diagnosed with ADHD through 2011. In addition, the CDC says that parents reported 3.5 million children and teenagers taking medications to treat ADHD, a 28 percent increase from 2007–2011.

In the new study, researchers identified 5,315 pediatric patients in the CDC’s National Health and Nutrition Examination Survey (NHANES) and compared children who reported taking ADHD medications with survey participants not on these medications.

Researchers discovered that children on ADHD medication had lower bone mineral density in the femur, femoral neck, and lumbar spine.

Approximately 25 percent of survey participants on ADHD medication met criteria for osteopenia — a condition characterized by lower than normal peak bone density. This incidence of osteopenia was significantly higher compared to participants not on medication.

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, explains Dr. Rivera.

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.

The findings are important because most skeletal growth occurs by ages 18-20. As a result, physicians should realize the potential threat that ADHD medications pose to maturing bones and consider nutritional counseling and other preventative measures, explains Dr. Rivera.
