Middle-aged whites account for suicide spike

Researchers at Johns Hopkins University studied suicide cases from 1999 to 2005. They found the suicide rate for whites 40-to-64 years old jumped 19 percent for women and 16 percent for men.

These latest figures show a major shift from teens, young adults and the elderly. Experts also conclude 90 percent of adults who commit suicide have a diagnosable mental disorder.

The study appears online in the American Journal of Preventative Medicine.
