Minority Kids Less Likely to Get ADHD Diagnosis?
Finding points to possible disparities in care
MONDAY, June 24 (HealthDay News) -- Minority children are significantly less likely than their white peers to be diagnosed or treated for attention-deficit/hyperactivity disorder (ADHD), new research shows.
The study, which is published online June 24 and in the July print issue of the journal Pediatrics, followed more than 17,000 children across the nation from kindergarten to eighth grade. Researchers regularly asked parents if their children had been diagnosed with ADHD.
Even after taking into account a host of factors that may influence behavior, attention and access to health care, researchers found that Hispanic and Asian children and those of other races were about half as likely to receive a diagnosis as whites. Blacks were about two-thirds less likely to be recognized as having problems with attention or hyperactivity as whites.
In addition, when minority children were diagnosed, they were less likely to receive medication than white kids with ADHD, the investigators found.
The study can't say, however, whether the differences mean that ADHD is being underdiagnosed in minorities or overdiagnosed in whites. Previous research has raised both possibilities.
A study published in the journal Clinical Psychology Review in 2009, for example, found that despite having more symptoms of distractibility and hyperactivity, black children were diagnosed with ADHD less often than whites.
On the other hand, a study published in April 2012 in the Canadian Medical Association Journal found that the youngest children in their school class were more likely to be diagnosed compared to the oldest children in those grades, suggesting that some doctors and teachers may mistake immaturity for ADHD, leading to overdiagnosis.
One expert suggested that socioeconomic and cultural differences may be at work.
Doctors still don't know if one or both problems may be driving the rates of lower diagnoses in minorities seen in the current study, said Dr. Tanya Froehlich, a pediatrician at Cincinnati Children's Hospital in Ohio.
"It does seem to be clear that there are some cultural differences at work, and also probably some differences in access to health care and access to health care information," said Froehlich, who was not involved in the research.
