DiscussionBetween 2001 and 2008, the prevalence of type 1 diabetes remained relatively stable, which is consistent with the findings of a recent report based on data from the Australian National Diabetes Register which suggests that the incidence of type 1 diabetes is increasing among children but not among young adults (Australian Institute of Health and Welfare). In contrast, the prevalence of type 2 diabetes has increased by 36% in the Australian adult population, which is consistent with previously reported trends in non-specific diabetes (Atlantis et al., 2009b). On average, the prevalence of type 1 and type 2 diabetes was 1.3 to 2.4 times higher for people with psychopathology by any definition (psychological distress, antidepressants, and/or anxiolytic medications) after adjusting for covariates socio-demographic. The absence of a significant interaction between surveys implies that the increased odds of both type 1 and type 2 diabetes in people with psychopathology were consistent over the 8-year period. Furthermore, the increased odds of diabetes, particularly type 2 diabetes, have been partially explained by unhealthy lifestyle behaviors which support findings and interpretations of previous prospective cohort studies (Atlantis et al., 2010; Chiu et al., 2010; Wilkins and Sambamoorthi, 2011). ). This suggests that effective lifestyle interventions could help mitigate the persistent excessive burden of diabetes and comorbid psychopathology, and that people with type 2 diabetes are likely to benefit more than those with type 1 diabetes. Lifestyle interventions are difficult to implement in practice (Atlantis et al., 2009a). Studies to inform policy and decision-making on the organization and delivery of multidisciplinary care are needed to comprehensively evaluate the benefits and risks of effective interventions for comorbid psychopathology and diabetes. A comprehensive study of serial and representative population-based data sources shows that the prevalence of both type 1 and type 2 diabetes was consistently higher for people with psychopathology from 2001 to 2008, which was partially explained from unhealthy lifestyle behaviors, particularly for people with type 2 diabetes. diabetes. Effective lifestyle interventions could help mitigate the persistent excessive burden of diabetes in people with comorbid psychopathology, but these are difficult to implement in practice. Trials are needed to inform policy and decision-making on the organization and delivery of multidisciplinary interventions for psychopathology, diabetes and unhealthy lifestyle behaviors.
