Jackson CA, et al. - In this retrospective cohort study, researchers determined the incidence of T2D in people with a history of hospitalization for major mental illness compared with no mental illness in Scotland by time period and sociodemographics. National Scottish population-based records were used to create cohorts with a hospital record of schizophrenia, bipolar disorder, or depression or no mental illness and to determine diabetes incidence. During 2001–2015, 254,136 diabetes cases were identified. Findings revealed that there seems to be widening disparities in the incidence of diabetes between individuals with and without major mental illness. Major mental illness has a greater impact on the risk of diabetes in women and people residing in more deprived areas, which has implications in this vulnerable population for intervention strategies to lessen diabetes risk. For schizophrenia and depression, the relative risks of diabetes incidence were higher among women than men but comparable to bipolar disorder.
