Researchers urged doctors to be on the lookout for signs of trouble in adopted teen patients but said parents should not be overly alarmed by the results.
"While our findings suggest that adoptees may have an elevated risk for suicide attempt, the majority of the adopted individuals in our study were psychologically well-adjusted," lead author Margaret Keyes, a psychologist at the University of Minnesota in Minneapolis, said.
Suicide is the third leading cause of death for young people between the ages of 10 and 24 years old, according to the Centers for Disease Control and Prevention. According to the agency, 4,600 youth deaths each year in the U.S. are suicides, and a much larger number of young people make attempts to take their own lives.
Previous research in Sweden found that adopted kids in that country were more likely to attempt suicide than nonadopted kids, but no comparable study had been done in the U.S., according to Keyes and her coauthors writing in the journal Pediatrics.
