Depressive disorders and significant levels of depressive symptoms are common in patients with type 2 diabetes, according to results published in Diabetes Medicine.
The researchers suggest that clinicians should take a more comprehensive approach to diabetes management that includes mental health interventions to improve clinical outcomes.
The study included people with type 2 diabetes aged 18 to 65 years who were treated in outpatient settings across 14 different countries (n=2783). Participants underwent a psychiatric interview and completed the Patient Health Questionnaire and the Problem Areas in Diabetes scale.
Of the 2783 participants, 10.6% were diagnosed with current major depressive disorder, and 17.0% reported moderate to severe levels of depressive symptoms (Patient Health Questionnaire scores >9).
The researchers found that current major depressive disorder was significantly associated with sex (women; P <.0001), a lower level of education (P <.05), doing less exercise (P <.01), higher levels of diabetes distress (P <.0001), and a previous diagnosis of major depressive disorder (P <.0001).
Despite the prevalence of depressive disorders and symptoms in the participants, the proportion of those who had a diagnosis or treatment for their depression was low and nonexistent, depending on the country (0%-29.6%).
“Our findings indicate that the identification and appropriate care for psychological and psychiatric problems is not the norm and suggest a lack of the comprehensive approach to diabetes management that is needed to improve clinical outcomes,” the authors concluded.
