Abstract
This cohort profile describes one of the largest linked datasets in the world concerning the health of people with intellectual disability. The cohort comprises a retrospective group of 100,089 individuals with intellectual disability who received disability and/or health services in New South Wales, Australia. Of these participants, 34% were female, with a median age at cohort entry of 3 years (interquartile range, 0-19). A separate comparator cohort included 455,677 individuals, matched by 5-year age group, sex, and residential postcode at a 5:1 ratio. Initial results indicate that between 2001 and 2018, people with intellectual disability experienced more than double the rate of hospitalisations (538 vs. 235 per 1,000 person-years), as well as markedly higher rates of emergency department presentations (707 vs. 379 per 1,000 person-years) and use of ambulatory mental health services (1,012 vs. 157 per 1,000 person-years), relative to the comparator cohort. The largest disparities in hospital admissions were for mental disorders, dialysis, and diseases of the nervous system and sense organs. Furthermore, individuals with intellectual disability had more than double the rate of dispensed medications found in the comparator cohort. Of these medications, 46.6% were for the treatment of nervous system conditions, as opposed to 24.7% for the comparator cohort. The mean±standard deviation age at death was 52±19 years for people with intellectual disability and 64±22 years for the comparator participants.
Summary
Key Message
This cohort study of individuals with intellectual disability is one of the largest internationally looking at health profiles and health service use. The goal is to improve the health and well-being of individuals with intellectual disability by informing the development of services, variations in prescribing practices, and access to preventative health services.

Abstract
OBJECTIVES
Studies on the association between disabilities and tuberculosis (TB) are scarce. We aimed to assess the risk of active TB disease among people with disabilities.
METHODS
We conducted a nationwide serial cross-sectional study using national registry linkage databases from 2008 to 2017. The crude and age-standardized and sex-standardized incidence rates of TB were analyzed for each year according to the presence, type, and severity of disabilities. The crude incidence rate and odds of developing TB disease were examined with a multivariable logistic regression model using data from 2017.
RESULTS
The overall incidence of active TB decreased between 2008 and 2017. The age- and sex-standardized incidence rates of TB disease among people with disabilities were significantly higher than among those without disabilities throughout all observed years (p<0.001). As of 2017, the population with disabilities had a higher crude incidence rate of active TB disease than that without disabilities (119.9/100,000 vs. 48.5/100,000 person-years, p<0.001), regardless of sex, income level, and place of residence. Compared to those without disabilities, those with disabilities had higher odds of active TB (adjusted odds ratio [aOR], 1.19; 95% confidence interval [CI], 1.15 to 1.24). Individuals with mental disabilities (aOR, 1.51; 95% CI, 1.24 to1.84) had the highest odds of active TB incidence, followed by those with developmental disabilities (aOR, 1.30; 95% CI, 1.09 to 1.55).
CONCLUSIONS
People with disabilities are at a greater risk of developing TB disease. Active screening and care for TB cases would be beneficial for people with disabilities.
Summary
Korean summary
장애가 있는 사람은 이차적 건강 문제가 발생할 가능성이 더 높고 그들의 건강결정요인은 결핵 발생 위험 요인과 겹친다. 장애인은 비장애인에 비해 연령과 성별에 관계없이 활동성 결핵 발병률이 현저히 높았으며, 장애 유형 중 정신장애와 발달장애가 결핵에 더 취약한 것으로 나타났다. 장애인과 같이 결핵 감염 위험이 있는 취약계층을 파악하고 이들에게 결핵진단 및 항결핵치료의 어려움을 극복할 수 있도록 다학제적 지원을 제공하는 것이 중요하겠다.
Key Message
People with disabilities are more likely to develop secondary health conditions and their social determinants of health overlap with the risk factors for developing TB disease. We found that compared to people without disabilities, a markedly higher incidence of active TB disease among people with disabilities regardless of age and sex, and mental and developmental disabilities among types of disability were more prone to TB disease. It is critical to identify the vulnerable populations, such as people with disabilities, at risk of developing TB infection and provide them with multidisciplinary support to overcome any barriers during TB diagnosis and anti-TB treatment.
