Abstract

Study Objective. To estimate and compare the prevalence of dementia and depression among adults with and without developmental disabilities (DDs). Methods. We linked data from several provincial administrative databases to identify persons with DDs. We matched cases with DD with persons without DD as to sex, age, and place of residence. We estimated the prevalence of dementia and depression and compared the two groups using the Generalized Estimating Equations (GEEs) technique. Results. The estimated prevalence of depression and dementia among younger adults (20–54) and older adults (50+) with DD was significantly higher than the estimated rates for the matched non-DD group (Depression: younger adults: RR = 2.96 (95% CI 2.59–3.39); older adults: RR = 2.65 (95% CI 1.84–3.81)), (Dementia: younger adults: RR = 4.01 (95% CI 2.72–5.92); older adults: RR = 4.80 (95% CI 2.48–9.31)). Conclusion. Significant disparities exist in mental health between persons with and without DDs.
