Prevalence of psychiatric conditions in people with intellectual disability: A record linkage study in New South Wales, Australia.

ABSTRACT:

Objective

To compare the prevalence of psychiatric conditions in a population-based cohort of people with intellectual disability and matched comparators in New South Wales, Australia.

Method

The study cohort included 97,644 people with intellectual disability and 451,502 comparators aged ⩾ 5 between 1 July 2001 to 30 June 2018. We used linked records of hospital admissions, emergency department presentations, ambulatory mental health service contacts, and Medicare rebates to identify any, serious, and specific psychiatric conditions.

Results

People with intellectual disability showed greatly elevated period prevalence of any psychiatric condition (76.0% vs 38.3%), serious mental illness (16.2% vs 5.1%), and all specific psychiatric conditions compared to comparators.
