Abstract

Objectives: Anxiety disorders are significant predictors of suicidality and are proposed to be independent risk factors for suicide attempts. They are common in people with type 2 diabetes (T2DM) and are associated with longer duration of diabetes and poorer treatment outcomes. The aim was to examine associations between anxiety disorders and suicidal thoughts and behaviour in people with T2DM, to establish the prevalence of suicidality among people with T2DM in the selected European countries and to examine whether anxiety disorders were predictive of current outcomes of suicidality in this population using data from the International Prevalence and Treatment of Diabetes and Depression study.

Methods: The study sample comprised 1063 adults with T2DM from 6 European countries. The presence of anxiety disorders and suicidality was assessed with the MINI International Neuropsychiatric Interview. The group of participants with current suicidal risk was compared with the group of participants with no suicidal risk.

Results: The participants from Germany were more likely to report suicidality than those from other countries, whereas people from Serbia and Ukraine were less likely to report it. Depression and anxiety disorders significantly contributed to the increased presence of suicidality among people with T2DM. Agoraphobia was a significant predictor of suicidality when controlling for depression. The participants with T2DM and comorbid agoraphobia had 4.86 times higher odds to report suicidality than those without agoraphobia.

Conclusions: Agoraphobia was a significant predictor of suicidality in people with T2DM.
