Impact of Anxiety Disorders on Mortality for Persons With Diabetes: A National Population-Based Cohort Study

[Psychodiabetology]

People affected by diabetes mellitus often have difficulties coping with their condition. This can be further worsened by psychological co-morbidities (e. g., depression or anxiety disorders). Both factors are associated with diabetes-specific problems (e. g., persistent hyperglycaemia, recurrent hypoglycaemia), but also with diabetes complications or comorbid somatic diseases. When psychotherapeutic or psychopharmacological treatment is indicated, it is essential to take into account the particularities of diabetes and the different types of diabetes. This review focuses on adults only and includes a brief description of the clinical features and therapeutic goals in diabetes mellitus. Critical diabetic symptoms that should result in specific interventions (yellow flags) as much as symptoms that require immediate intervention (red flags) are highlighted. Finally, psychological and behavioural factors as well as mental comorbidities that are relevant to the management of diabetes mellitus are discussed.

Anxiety Disorders in Patients With Somatic Diseases

OBJECTIVE

Anxiety disorders are among the most frequent mental disorders and are associated with a range of short- and long-term impairments and disabilities. Relatively little is known about anxiety disorders in patients with somatic diseases, and the present literature review highlights the current research in this field, data about prevalences of anxiety disorders in patients with somatic diseases, and the effectiveness of interventions. This article also introduces a comprehensive model of inpatient treatment and summarizes the evidence pertinent to this approach.

METHODS

A narrative review is presented with regard to prevalence and treatment of anxiety disorders in patients with somatic diseases. The effects of inpatient treatment are illustrated based on a case report.

RESULTS

This review indicates that anxiety disorders are more common in patients with somatic diseases, with prevalence estimates ranging from 2.5% to 55%, than in the general population. Several outpatient treatment options exist, with substantial support for the effectiveness of cognitive behavioral therapy, psychodynamic therapy, and pharmacotherapy. We also provide evidence in support of psychosomatic inpatient treatment for patients with anxiety disorders that are comorbid with somatic diseases.

CONCLUSIONS

Anxiety disorders are common in patients with somatic diseases, and several effective treatment options exist, including cognitive behavioral therapy and pharmacological interventions. We also provide support for the effectiveness of inpatient treatment with unique opportunities for multidisciplinary psychosomatic treatment of anxiety disorders with comorbid somatic diseases.

Comorbid elevated symptoms of anxiety and depression in adults with type 1 or type 2 diabetes: Results from the International Diabetes MILES Study

AIMS

We examined: (a) the prevalence of comorbid elevated symptoms of anxiety/depression; (b) its demographic/clinical correlates; (c) associations with self-care behaviors, by diabetes type.

METHODS

Cross-sectional self-report data of 6590 adults with diabetes (42% type 1; 58% type 2) from the Australian and Dutch Diabetes MILES studies were used. Elevated symptoms of anxiety/depression were defined as GAD-7 ≥ 10/PHQ-9 ≥ 10.

RESULTS

In both diabetes types, comorbid elevated symptoms of anxiety/depression were present in 9% and symptoms of anxiety alone in 2%; symptoms of depression alone were present in 8% of adults with type 1 diabetes and 11% with type 2 diabetes. Shorter diabetes duration (type 1 only) was the only characteristic that distinguished those with comorbid elevated symptoms of anxiety/depression but not those with symptoms of anxiety/depression alone from the reference group (no/minimal symptoms of anxiety/depression). Those with comorbid elevated symptoms of anxiety/depression had increased odds of sub-optimal diabetes self-care behaviors compared with the reference group, with higher odds than those with symptoms of anxiety or depression alone.

CONCLUSIONS

Comorbid elevated symptoms of anxiety/depression affected one in ten respondents, who also had increased odds of suboptimal diabetes self-care. Those with shorter type 1 diabetes duration may be at increased risk.
