OBJECTIVE: To survey unnatural deaths among teenagers in northern Sweden and to suggest preventive measures.

SETTING: The four northernmost counties (908,000 inhabitants, 1991), forming 55% of the area of Sweden.

MATERIAL AND METHODS: All unnatural teenager deaths from 1981 through 2000 were identified in the databases of the Department of Forensic Medicine in Umea, National Board of Forensic Medicine. Police reports and autopsy findings were always studied, social and hospital records if present.

RESULTS: Three hundred and fifty-five deaths were found, of which 267 (75%) were males and 88 (25%) females. Ninety out of 327 (28%) tested positive for alcohol. Two hundred and forty-eight (70%) were unintentional and 102 (30%) were intentional deaths, and five (1%) were categorized as undetermined manner of death. Unintentional deaths decreased while the incidence of intentional deaths remained unaffected by time.

CONCLUSIONS: Injury-reducing measures have been effective concerning unintentional deaths and the fall in young licensed drivers due to the economical recess have probably also contributed to the decrease. However, there were no signs of decreasing numbers of suicides during the study period, which calls for resources to be allocated to suicide prevention.

Abstract [en]

A significant number of teenagers are killed each year by unintentional or intentional injuries. A teenager is in a vulnerable phase of her/his life, going from being a child to adult. This transition often includes testing the limits of their capabilities, which can include, e.g., high speed driving, testing alcohol and other drugs, including drinking and driving. The development from child to adult includes different psychological stress factors, such as, e.g., school problems, broken love affairs and bullying. The demands – perceived or real – also increases over time and vulnerable individuals can turn to self-harm and in the most extreme case suicide.

The aim of this thesis was to investigate teenager fatalities in the northern half of Sweden and to suggest preventive measures.

A survey of teenager fatalities during a twenty-year period revealed that the incidence of unintentional (n=248) deaths decreased, while intentional (n=102) deaths were unaffected over time. Most unintentional deaths were transportation related (n=204) while most of the intentional deaths were suicides (n=88). Twenty-eight percent of the decedents were test-positive for alcohol at autopsy.

In a series of three studies, teenager suicides were investigated in depth, firstly through an interview study with the investigating police officer in charge of the investigation of a teenager suicide. Most of the suicides occurred in rural and depopulated areas despite the fact that most teenagers live in the larger cities along the coastline. A majority of the suicides appeared to be planned. Females, contrary to males, often had a psychiatric history. One of the conclusions was that police officers provide essential information concerning the circumstances around a teenager suicide.

Parents who had lost a child through suicide, and in some cases siblings, were interviewed 15-25 months after the suicide. It was striking how the life of the surviving family members were still affected by the devastating trauma of the suicide; most parents testified that they were still struggling with the question “why?” and that they were thinking of their lost child every day. Post suicide support was often badly timed and insufficient, especially for the younger siblings. The family doctor has an important role as a co-ordinator of a long-term individually formulated support scheme for the bereaved.

Evidence of suicide contagion and suicide cluster formation, i.e., one teenager suicide led to another suicide, was found in these studies, and two suicide clusters were identified, with links between the victims in each cluster. Both clusters occurred within a geographical and timely proximity. Everyone involved in the well-being of the young should be aware of the risk of contagion and suicide cluster formation.

The fifth study concerned 12,812 teenagers who visited the Emergency Room at Umeå University Hospital due to an injury during 1993 through 2006. Sixty-one of these were found dead through 2007, 49 by unnatural (of which 38 were included) and 12 by natural causes. The standard mortality rate for unnatural death was calculated to 1.44 (1.02-1.98), confirming an increased risk of premature death. In many of these deaths, alcohol and drugs may have contributed. By increasing the awareness among health professionals that injury can predict a premature death - primarily among those who develop substance abuse - some premature deaths may be prevented by early intervention.

This thesis confirms that most teenagers die from unnatural causes, mostly in transportation-related events and by suicide. By studying these deaths, preventive measures that could save lives have been suggested.
