"Data Trends" reports present summaries of research on mental health services for children and adolescents and their families. The article summarized in this "Data Trends" presents the results of a survey investigation of the prevalence and predictors of suicidality among 879 urban adolescents. In the U. S., suicide is the third leading cause of death among young people 15-24 years, and the fourth leading cause of death among children 10-14 years. Research indicates that more than nine out of ten children who commit suicide have a pre-existing mental health problem. In addition, there is evidence that the rates of suicide among different ethnic groups have changed substantially. For example, suicide rates among young African American males (15-19 years) increased by 105% between 1980 and 1996. The authors recognize that the additional selection procedures required for this survey may have introduced sample bias. In the larger Reach for Health (RFH) study, sample attrition from middle to high school was greatest among males, and those who reported violence towards others. Thus at-risk males may be under represented in this sample. Nevertheless, the results of this research have important implications for efforts to address suicide among young people. The findings that reduced risk is associated with family closeness (rather than household constellation), and with longer time living in the same neighborhood, suggest that improving access to supportive networks at home and in the community should be part of intervention strategies. Addressing depression among young people is clearly important. However, in this study not having basic needs met contributes independently to suicide risk. Thus addressing economic deprivation is an essential part of a comprehensive approach to suicide reduction. (Contains 1 table and 1 note.)
