Abstract

Background
Childhood adversity (CA) carries an increased risk of developing later mental health (MH) problems and suicidal behaviour. This study aimed to summarise hospital attendances for CA and MH in young people who later died by suicide.
Methods
This study is a retrospective longitudinal case control study. Lifetime Scottish inpatient acute and psychiatric records were summarised for individuals born since 1981 who died by suicide in the period 1991-2017 (cases), and controls (1:10) matched on sex, age, and postcode. Relevant records were coded MH (including self-harm) and/or CA. Descriptive statistics and odds ratios (OR) were computed.
Results
Data for 2,477 and 24,777 ‘cases’ and ‘controls’ were extracted, of whom 2,106 cases (85%) and 13,589 controls (55%) had lifespan hospital records. Mean age at death for cases was 23.7 (SD=4.9) and 75.9% were male. Psychiatric records formed 11.6% and 1.4% of cases and controls, respectively.
For the age range >=10 to <18, CA was recorded for 160 (7.6%) cases and 371 (2.7%) controls, corresponding to OR=2.9 (95%CI: 2.4-3.6). This was compared with MH at 458 (21.7%) cases and 560 (4.1%) controls and OR=6.5 (95%CI: 5.7-7.4). The highest adjusted ORs were for self-harm episodes recorded in general hospital with aORmale=6.56 (95%CI: 4.96-8.68) and aORfemale=6.87 (95%CI: 4.99-9.48).
Conclusion
All CA and MH presentations in inpatient hospital records were associated with greater risk of subsequent suicide, with the strongest association for self-harm.
