  • + Notes

    Intentional self-harm includes purposely self-inflicted poisoning or injury or attempted suicide with intent based on notes recorded by the treating clinician. This indicator measures people admitted to hospital after self-harm. It is not a direct measure of the number of people in the NSW population who make suicide attempts.  

    Only NSW residents are included. Rehabilitation episodes are excluded. Figures are based on where a person resides, rather than where they are treated. Hospital separations were classified using ICD-10-AM. Rates were age-adjusted using the Australian population as at 30 June 2001.

    Numbers for recent years include an estimate of the small number of hospitalisations of NSW residents in interstate public hospitals, data for which were unavailable at the time of production. Further details can be found in the Methods tab in the following HealthStats NSW indicator:

    LL/UL 95%CI = lower and upper limits of the 95% confidence interval for the point estimate. Data for some LHDs may not be included individually due to low numbers. All LHDs include Albury Local Government Area and those LHDs where numbers are low and records where the LHD was missing or not stated.

      Latest available information

      Latest available data for adults in NSW

      • 15.1% of adults aged 16 years and over (12.9% of men and 17.3% of women) experienced high or very high levels of psychological distress, as estimated from the 2017 NSW Adult Population Health Survey (self-reported using Computer Assisted Telephone Interviewing or CATI). 

      • 11.0% of adults aged 18 years and over (9.0% of males and 12.5% of females) in NSW experienced high or very high levels of psychological distress, as estimated from the 2014-15 Australian Health Survey (interviewer-administered questionnaire).

      • Overall suicide rates dropped in NSW between 1997 and 2007 but has increased since this time. In 2017, 868 people died by suicide and males accounted for around 77.6% of these deaths.

      • In 2017-18, there were 7,236 hospitalisations of NSW residents for intentional self-harm. Females accounted for 63% of these hospitalisations.

      • In 2017, 14.0% of secondary school students reported high levels of psychological distress in the previous six months (9.7% of males and 18.2% of females). The proportion of students reporting high levels of psychological distress has remained stable over the last 3 years (2014 to 2017).

      • Generally, a lower proportion of elderly adults have high levels of psychological distress than the overall adult population in NSW.

      • The least socioeconomically disadvantaged adults had lower levels of psychological distress than the overall adult population in NSW.

      • The proportion of adults reporting high and very high levels of psychological distress has remained fairly stable over the last decade.

    • Introduction: Mental health


      Mental health disorders relate to behaviours and conditions which interfere with social functioning and capacity to negotiate daily life. Mental problems are also associated with higher rates of health risk factors, poorer physical health, and higher rates of deaths from many causes including suicide.

      The classification of mental and behavioural disorders is difficult and warrants close attention to the types of disorders and syndromes which are included and excluded when comparing results from different sources. Further discussion of this issue is contained in the Methods tab.

      Burden of disease of mental conditions in Australia

      Mental ill health is one of the leading causes of non-fatal burden of disease and injury in Australia. Mental ill health was estimated to account for 12% of the disease burden in Australia in 2015, with anxiety and depression, alcohol abuse and personality disorders accounting for almost three-quarters of this burden. Only 2.5% of the burden from mental disorders is due to mortality, most of which is accounted for by fatal outcomes associated with substance abuse (AIHW 2019).
