Psychiatric co-morbidity with type 1 and type 2 diabetes mellitus
View/ Open
Abstract
We evaluated the prevalence of diabetes comorbidity in Greek psychiatric patients, differences between type 1 and type 2 diabetics and the outcome of psychiatric disorder. Of 800 psychiatric patients meeting our inclusion criteria, 82 [10.2%] had diabetes mellitus; 28% type 1 and 72% type 2. The mean age at onset of mental illness was earlier for type 1 diabetics [mean 26.95, SD 9.09 years] than type 2 [mean 33.22, SD 10.71 years] [P < 0.015] and the duration of untreated mental illness was shorter [mean 2.86, SD 3.06 years compared with mean 4.13, SD 6.24 years for type 2 diabetics]. Schizophrenia was the commonest psychiatric diagnosis in both types of diabetes. There was no significant difference in outcome of psychiatric disorder between the 2 types of diabetics. Existence of diabetes mellitus [regardless of type], duration of untreated mental illness and lack of patient therapeutic education were negative predictors of [unfavourable] outcome. These findings provide evidence of a high prevalence of diabetes in psychiatric patients and that having diabetes has an adverse effect on outcome of psychiatric illnessCitation
