Abstract [en]

Background: We aimed to compare the prevalence of impulsive suicide attempts (ISA) among young adults and those over 25 who present at hospital in connection with attempted suicide. We also aimed to identify factors associated with ISA in young adults and to assess medical severity as well as the probability of repeated suicide attempts in this age group.

Method: A prospective multicentre cohort study included hospital known cases of suicide attempt (N = 666). The prevalence of ISA was compared between young adults (18-25) and adults aged > 26. We used logistic regression models to identify factors associated with ISA, associations of ISA with high medical severity and prediction of new fatal or non-fatal suicide attempts within 6 months.

Results: 43.7% of the young patients had made an ISA, and 30.2% among those aged > 26 (p = 0.001). Among the young, substance use disorder was associated with ISA; crude odds ratio (OR) 2.0 (1.0-4.2), and adjusted OR 2.1 (0.99-4.4). Affective disorder and unemployment/sickness absence implied lower odds of ISA. ISA resulted in injuries of high medical severity as often as more planned attempts and non-fatal or fatal repetition within 6 months was equally common (30%) in both groups.

Limitations: The study was set in psychiatric emergency services, which limits the generalizability.

Conclusions: Clinicians should acknowledge that suicide attempts among youth often occur without previous planning and may result in medically severe injuries. The probability of new fatal or non-fatal suicide attempts should be kept in mind also after an impulsive suicide attempt.
