Abstract
Suicide in children and young adults is a leading cause of premature mortality, and there is a need to develop a more profound understanding of the factors that contribute to these deaths. This study is part of the nationwide Retrospective Investigation of Health Care Utilization in Individuals who died by Suicide in Sweden 2015, conducted at Lund University, Sweden. The aim was to examine symptoms and diagnoses in children and young adults who died by suicide, as documented in their medical records at their last visits for primary care, somatic specialist care, or psychiatric care 24 months prior to suicide, and to apply contemporary psychological research in youth suicidality to the findings to formulate clinical implications. The proportions of symptoms and diagnoses in children (0-17 years), young adults (18-24 years), males, and females are described. The main symptoms noted in the cohort were depressive symptoms (28%), anxiety symptoms (26%), and pain (25%). The diagnoses predominately covered mental and behavioural disorders, and the most frequent of the mental and behavioural diagnoses were neurotic, stress-related, and somatoform disorders (32%) and mood (affective) disorders (29%). The diagnoses and symptoms were not sufficient to uncover suicidality in children and young adults. The clinical implications for alternative assessments and preventive interventions are discussed.
