This Canadian study, reported by Reuters, might lead one to wonder:
TORONTO (Reuters) - Children from broken marriages are twice as likely to be prescribed attention-deficit drugs as children whose parents stay together, a Canadian researcher said on Monday, and she said the reasons should be investigated.
More than 6 percent of 633 children from divorced families were prescribed Ritalin, compared with 3.3 percent of children whose parents stayed together, University of Alberta professor Lisa Strohschein reported in the Canadian Medical Association Journal.
The study of more than 4,700 children started in 1994, while all the families were intact, Strohschein said. They followed the children's progress to see what happened to their families and to see what drugs were prescribed.
"It shows clearly that divorce is a risk factor for kids to be prescribed Ritalin," Strohschein said.
...Ritalin, known generically as methylphenidate, is a psychostimulant drug most commonly prescribed for the treatment of attention-deficit hyperactivity disorder in children.
There is a big debate in much of the developed world over whether it may be over-prescribed -- given to children who do not really need it. In March, a University of California, Berkeley study found that the use of drugs to treat ADHD has more than tripled worldwide since 1993.
