Suicide is one of the top five leading causes of death in the 15–19 year group, and around 90 per cent of these individuals have underlying psychiatric disorders. Completed suicide is extremely rare before puberty, rising to 4–8 per 100 000 in the 15–19 age groups.

About three-quarters of these are males, and young people who commit suicide are four times more likely than the general population to have a family history of suicide.

The most common comorbidities are mood disorders, alcohol and substance abuse, anxiety disorder, eating disorders, and chronic physical diseases. About one-third of completed suicides had made at least one previous attempt to end their life. Factors that are thought to be involved in the aetiology of suicide and attempted suicide are BELOW:


  • Family history of suicide or deliberate selfharm
  • Self-harm in close friends
  • Familial mental health problems
  • Neurotransmitter dysregulation: low serotonin Psychiatric disorders


  • Depression
  • Substance abuse
  • Conduct disorder
  • Anxiety disorder
  • Schizophrenia
  • Past suicide attempt Cognitive factors
  • Low selfesteem
  • Hopelessness
  • Guilt
  • Bullying
  • Confusion regarding sexual orientation
  • Physical, emotional, or sexual abuse Stressful life events


  • Family discord
  • Parental divorce
  • Death of loved one Poor care or neglect Imitation— exposure to real or fictional accounts of suicide

The strongest predictor of future suicide risk is past suicide attempts. Deliberate self-harm (DSH) is any act with a non-fatal outcome, which is undertaken with the intention of causing harm to self. It is hard to obtain accurate figures of the prevalence and incidence of DSH as most young people never present to psychiatric services.

Surveys of schoolage teenagers suggest 10 per cent of 15–16 year olds have harmed themselves in the previous year, with the majority of these having done it more than once. Females Are four times more likely to self-harm than males.

The most common methods of self-harm are cutting and taking paracetamol overdoses.
