Early violent death among delinquent youth: a prospective longitudinal study.
OBJECTIVE
Youth processed in the juvenile justice system are at great risk for early violent death. Groups at greatest risk, ie, racial/ethnic minorities, male youth, and urban youth, are overrepresented in the juvenile justice system. We compared mortality rates for delinquent youth with those for the general population, controlling for differences in gender, race/ethnicity, and age.


METHODS
This prospective longitudinal study examined mortality rates among 1829 youth (1172 male and 657 female) enrolled in the Northwestern Juvenile Project, a study of health needs and outcomes of delinquent youth. Participants, 10 to 18 years of age, were sampled randomly from intake at the Cook County Juvenile Temporary Detention Center in Chicago, Illinois, between 1995 and 1998. The sample was stratified according to gender, race/ethnicity (African American, non-Hispanic white, Hispanic, or other), age (10-13 or > or =14 years), and legal status (processed as a juvenile or as an adult), to obtain enough participants for examination of key subgroups. The sample included 1005 African American (54.9%), 296 non-Hispanic white (16.2%), 524 Hispanic (28.17%), and 4 other-race/ethnicity (0.2%) subjects. The mean age at enrollment was 14.9 years (median age: 15 years). The refusal rate was 4.2%. As of March 31, 2004, we had monitored participants for 0.5 to 8.4 years (mean: 7.1 years; median: 7.2 years; interquartile range: 6.5-7.8 years); the aggregate exposure for all participants was 12944 person-years. Data on deaths and causes of death were obtained from family reports or records and were then verified by the local medical examiner or the National Death Index. For comparisons of mortality rates for delinquents and the general population, all data were weighted according to the racial/ethnic, gender, and age characteristics of the detention center; these weighted standardized populations were used to calculate reported percentages and mortality ratios. We calculated mortality ratios by comparing our sample's mortality rates with those for the general population of Cook County, controlling for differences in gender, race/ethnicity, and age.


RESULTS
Sixty-five youth died during the follow-up period. All deaths were from external causes. As determined by using the weighted percentages to estimate causes of death, 95.5% of deaths were homicides or legal interventions (90.1% homicides and 5.4% legal interventions), 1.1% of all deaths were suicides, 1.3% were from motor vehicle accidents, 0.5% were from other accidents, and 1.6% were from other external causes. Among homicides, 93.0% were from gunshot wounds. The overall mortality rate was >4 times the general-population rate. The mortality rate among female youth was nearly 8 times the general-population rate. African American male youth had the highest mortality rate (887 deaths per 100000 person-years).


CONCLUSIONS
Early violent death among delinquent and general-population youth affects racial/ethnic minorities disproportionately and should be addressed as are other health disparities. Future studies should identify the most promising modifiable risk factors and preventive interventions, explore the causes of death among delinquent female youth, and examine whether minority youth express suicidal intent by putting themselves at risk for homicide.
