Abstract Aims To examine the factors that are associated with changes in depression in people with type 2 diabetes living in 12 different countries. Methods People with type 2 diabetes treated in out-patient settings aged 18–65 years underwent a psychiatric assessment to diagnose major depressive disorder (MDD) at baseline and follow-up. At both time points, participants completed the Patient Health Questionnaire (PHQ-9), the WHO five-item Well-being scale (WHO-5) and the Problem Areas in Diabetes (PAID) scale which measures diabetes-related distress. A composite stress score (CSS) (the occurrence of stressful life events and their reported degree of ‘upset’) between baseline and follow-up was calculated. Demographic data and medical record information were collected. Separate regression analyses were conducted with MDD and PHQ-9 scores as the dependent variables. Results In total, there were 7.4% (120) incident cases of MDD with 81.5% (1317) continuing to remain free of a diagnosis of MDD. Univariate analyses demonstrated that those with MDD were more likely to be female, less likely to be physically active, more likely to have diabetes complications at baseline and have higher CSS. Mean scores for the WHO-5, PAID and PHQ-9 were poorer in those with incident MDD compared with those who had never had a diagnosis of MDD. Regression analyses demonstrated that higher PHQ-9, lower WHO-5 scores and greater CSS were significant predictors of incident MDD. Significant predictors of PHQ-9 were baseline PHQ-9 score, WHO-5, PAID and CSS. Conclusion This study demonstrates the importance of psychosocial factors in addition to physiological variables in the development of depressive symptoms and incident MDD in people with type 2 diabetes. Stressful life events, depressive symptoms and diabetes-related distress all play a significant role which has implications for practice. A more holistic approach to care, which recognises the interplay of these psychosocial factors, may help to mitigate their impact on diabetes self-management as well as MDD, thus early screening and treatment for symptoms is recommended.

Objective: In many epidemiologic studies, type 2 diabetes has been reported to be associated with severe mental illness (SMI) such as schizophrenia (SCZ), bipolar disorder (BPD), and major depressive disorder (MDD). However, the relationship between SMI and type 2 diabetes is bi-directional, and the causal relationship remains unclear due to various confounders. Therefore, a Mendelian randomization (MR) study is necessary to identify the causality between them. Research Design and Methods: We conducted a two−sample MR study to identify the causal effect of SMI on type 2 diabetes using the inverse-variance weighted (IVW), MR−Egger, MR− Egger with a simulation extrapolation, weighted median approach, and MR-Pleiotropy RESidual Sum and Outlier methods. The most appropriate method was selected according to the instrument variables assumption. Results: We found that MDD had a significant causal effect on type 2 diabetes from the results obtained using the IVW method (Odds ratio (OR): 1.191, 95% CI: 1.036−1.372, P = 0.014); however, this was not observed for BPD (IVW, OR: 1.006, 95% CI: 0.918−1.104, P = 0.892) or SCZ (IVW, OR: 1.016, 95% CI: 0.974−1.059, P = 0.463). The absence of reverse-causality between MDD and type 2 diabetes was also demonstrated from bidirectional MR studies. Conclusions: These results clearly reveal important knowledge on the causal role of MDD in the risk of type 2 diabetes without a residual confounding, whereas the causality of BPD and SCZ was not shown. Therefore, careful attention should be paid to MDD patients in type 2 diabetes prevention and treatment.

ABSTRACT BACKGROUND: Major depressive disorder (MDD) is commonly reported in patients with chronic hepatitis C (CHC); however, the factors behind the co-occurrence of these conditions have not been completely clarified yet. OBJECTIVE: We aimed to evaluate the frequency of mental disorders in CHC patients and to investigate variables associated with MDD. METHODS: CHC patients (n=151) attending a referral Centre for hepatitis were evaluated using the Mini-International Neuropsychiatry Interview and the Cut-Annoyed-Guilty-Eye (CAGE) Questionnaire. Multivariate analysis was used to evaluate independent covariates associated with current MDD. RESULTS: Seventy-six (50.3%) patients had, at least, one current psychiatric diagnosis with MDD (33.1%) being the most common. Current MDD was independently associated with age (≤50 yr.) (OR=2.57; 95%CI=1.25-5.29; P=0.01) and type 2 diabetes mellitus (OR=2.80, 95%CI=1.17-6.70; P=0.02). Cirrhosis was associated with type 2 diabetes mellitus (OR=5.09; 95%CI=1.73-15.04; P=0.03) and current alcohol abuse/dependence (OR=2.54; 95%CI=1.04-6.22; P=0.04). DISCUSSION: MDD is associated with type 2 diabetes in CHC patients. Even in the direct-acting antivirals (DAAs) era, characterized by great perspectives for the first ample cure of a chronic viral infection, we should ensure that the screening for psychiatric disorders takes place in the course of routine clinical care of patients chronically infected with hepatitis C virus.
