Datapoints: Recent Trends in Suicide Among U.S. Adolescent Males, 1992-2001

In the United States black youths have historically had lower suicide rates than white youths, but the gap has been narrowing because of an increase in the suicide rate among young black males (1).

Using the mortality database from the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (2), we determined trends in suicide deaths between 1992 and 2001 for white males and black males aged 15 to 19 years. Trends in suicide were estimated by using negative binomial rate regression analyses.

As Figures 1 and 2 show, the overall suicide rate among white males decreased by an average of 3.9 percent annually (p<.001). The firearm suicide rate decreased by 6.6 percent annually (p<.001), and the rate of suicide by other means decreased by 3.9 percent annually (p=.002). However, there was an annual increase of 3.2 percent for suicide by suffocation (mostly hanging) (p<.001). In contrast, the overall suicide rate among black males decreased by 7.3 percent annually (p<.001), and nearly all the decrease was explained by a 10.2 percent annual decrease in the firearm suicide rate (p<.001).

Possible explanations for the recent decline in the youth suicide rate include the enactment of gun laws intended to keep firearms from youths (3) and the increasing use of selective serotonin reuptake inhibitors in the treatment of pediatric depression (1).

The firearm suicide rate has fallen substantially in recent years among both white and black adolescent males. This decline may be part of an overall downward trend in firearm deaths (2). The recent increase in suffocation suicides among white male teenagers may indicate that method-specific substitution is occurring. Our data underscore the need for health care providers to assess the availability of lethal means, and the risk for their use, and to make recommendations for their removal or safe storage.
