Suicides Among Adolescents in a Major German City Abstract.

Objective

Adolescent suicide is a major contributor to the overall mortality in this age group. This study examined sex and age differences in suicide methods. Method: The investigation is based on death certificates from the years 1996 to 2019 of the city of Leipzig and includes all suicides in the age group under 25 years. The impact of sex and age on the method and location of suicide was examined using chi square statistics. Moreover, we verified the association between suicides and death by drug overdose through statistical regression.

Results

140 suicides were included in the study. The suicide methods differed between the age groups (χ² = 17,878; p = .022). Individuals under 21 years of age committed suicide almost exclusively by strangulation, jumping from heights, railway suicide, or deliberate intoxication. With the onset of early adulthood, the spectrum of methods expanded. Suicide methods were also different between the sexes (χ² = 35,166; p < .001): Male adolescents preferred highly lethal methods such as strangulation, whereas in female adolescents intoxication was the leading method of suicide, with a predominance of antidepressants. The annual rates of suicide and death by drug overdose were found to correlate (Pearson correlation = 0,571, p = .004). Minors (χ² = 3.125, p = .077) tended to avoid their own residential environment as a place of suicides compared to adults.

Conclusion

When assessing the individual suicide risk and weighing safeguarding measures in clinical practice, the differences shown in the choice of methods should be taken into account.
