Researchers from the University of Iowa College of Public Health have reported in the first broad study in the United States the frequency of two muscle-weakness disorders that strike mostly boys: Duchenne muscular dystrophy and Becker muscular dystrophy.

The study found that about one in 5,000 boys, between 5 and 9 years old, have the inherited disorders. It also shows the diseases appear to affect Hispanic boys more often than White or African-American boys, for reasons that are not well understood.

This new information gives doctors and health-care professionals valuable data, so they can better plan to care for those affected, especially as the diseases progress.
