Association between subthreshold depression and self-care behaviour in people with type 2 diabetes: a protocol for systematic review of observational studies

Reconsidering the role of depression and common psychiatric disorders as partners in the type 2 diabetes epidemic

Common psychiatric disorders (CPDs) and depression contribute significantly to the global epidemic of type 2 diabetes (T2D). We postulated a possible pathophysiological mechanism that through Bridge-Symptoms present in depression and CPDs, promotes the establishment of emotional eating, activation of the reward system, onset of overweight and obesity and, ultimately the increased risk of developing T2D. The plausibility of the proposed pathophysiological mechanism is supported by the mechanism of action of drugs such as naltrexone-bupropion currently approved for the treatment of both obesity/overweight with T2D and as separate active pharmaceutical ingredients in drug addiction, but also from initial evidence that is emerging regarding glucagon-like peptide 1 receptor agonists that appear to be effective in the treatment of drug addiction. We hope that our hypothesis may be useful in interpreting the higher prevalence of CPDs and depression in patients with T2D compared with the general population and may help refine the integrated psychiatric-diabetic therapy approach to improve the treatment and or remission of T2D.

Cardiovascular Health Behavior Prediction Model in Patients With Type 2 Diabetes

BACKGROUND

To prevent cardiovascular disease in adults with type 2 diabetes, it is necessary to identify the factors that affect cardiovascular health behavior.

OBJECTIVE

The aim of this study was to verify the causal relationship between illness perception and diabetes knowledge as cognitive representations, depression as emotional representations, self-efficacy as cognitive coping, and oral health and cardiovascular health behaviors as behavioral coping strategies. A hypothetical model was established based on a literature review and the self-regulation model.

METHODS

In this study, a cross-sectional survey design was used, and the participants were adults 30 years or older who had been given a diagnosis of type 2 diabetes for more than 6 months and were recruited from South Korea. Data from 272 participants were collected through face-to-face interviews or Google surveys in 2021, and analyzed using SPSS 25.0 and AMOS 22.0.

RESULTS

Oral health behavior (β = 0.26, P < .001) and self-efficacy (β = 0.16, P = .048) had a direct effect on cardiovascular health behavior, and illness perception (β = 0.24, P = .018) and depression (β = -0.25, P < .001) had an indirect effect through self-efficacy (β = 0.24, P = .016), with a total explanatory power of 19.1%. Oral health behavior was directly affected by illness perception and self-efficacy, and self-efficacy was directly affected by illness perception, diabetes knowledge, and depression (P < .05).

CONCLUSION

To practice cardiovascular health behaviors in adults with diabetes, self-efficacy for diabetes management should be enhanced. To this end, it is necessary to increase illness perception and knowledge, and reduce depression through cardiovascular disease prevention education for them, and the importance of oral health behaviors should also be emphasized.

Association Between Depression, Diabetes Self-Care Activity and Glycemic Control in an Arab Population with Type 2 Diabetes

PURPOSE

Poor self-care behavior and depression are associated with worse glycemic control, but the relationship between these variables is poorly reported. The present study aimed to describe self-care behaviors and explore the association between depression, self-care and glycemic control in people with type 2 diabetes in an Arab population.

PATIENTS AND METHODS

This study recruited 446 patients with type-2 diabetes from an outpatient clinic in Kuwait and completed assessments of diabetes self-care using the Summary of Diabetes Self-Care Activities (SDSCA) questionnaire and depression using the Patients Health Questionnaire-9 (PHQ-9) scales. Multiple linear regression models were used to determine the associations between depression, self-care behaviors and glycemic control.

RESULTS

Self-care behaviors were highest for medication taking (92.9%), an average for foot care (61.4%), blood glucose testing (60%) and healthy diet (55.7%), and lowest for exercise (27.1%). Depression, poor self-care activities and poor HbA1c levels were inter-correlated in univariate analysis (p< 0.03). In regression analysis, following healthful eating (B= -0.27, p< 0.001), general eating plan (B= -0.21, p= 0.01), more space carbohydrates evenly throughout the day (B= - 0.17, p= 0.03) and exercise at least 30 minutes (B= -0.17, p= 0.02) behaviors were associated with better HbA1c levels. However, depression was associated with poor scores of following a general eating plan (B= -0.20, p= 0.03), space carbohydrates evenly throughout the day (B= -0.21, p= 0.05), and exercising at least 30 minutes (B= -0.24, p= 0.03) behaviors. Depression scores were also associated with poor HbA1c levels (B= 0.32, p= 0.03). However, this association no longer persists after mutual adjustment with following a healthy diet (B= 0.14, p= 0.38) and exercise (B = 0.26, p = 0.08) behaviors.

CONCLUSION

Self-care activity was less than fifty percent in people with type 2 diabetes and higher activity was associated with better glycemic control. However, depression adversely affects self-care behaviors. To maintain and achieve glycemic control, diabetes educators might motivate people with type 2 diabetes to enhance their self-care activities, particularly those with depression symptoms and poor compliance with self-care activities.

Anxiety and/or depression: which symptoms contribute to adverse clinical outcomes after amputation?

BACKGROUND

One of the most serious complications of diabetes mellitus (DM) is a diabetic foot ulcer (DFU), with lower extremity amputation (LEA).

AIMS

This study aims to explore the role of anxiety and depression on mortality, reamputation and healing, after a LEA due to DFU.

METHODS

A sample of 149 patients with DFU who underwent LEA answered the Hospital Anxiety and Depression Scale and a sociodemographic and clinical questionnaire. This is a longitudinal and multicenter study with four assessment moments that used Cox proportional hazards models adjusted for demographic and clinical variables.

RESULTS

Rate of mortality, reamputation and healing, 10 months after LEA were 9.4%, 27.5% and 61.7%, respectively. Anxiety, at baseline, was negatively associated with healing. However, depression was not an independent predictor of mortality. None of the psychological factors was associated with reamputation.

CONCLUSION

Results highlight the significant contribution of anxiety symptoms at pre-surgery, to healing after a LEA. Suggestions for psychological interventions are made.

Prevalence and predictors of depression in type 2 diabetes mellitus

BACKGROUND

Type 2 diabetes mellitus (DM) is a multifactorial disease and can be described as a noncommunicable disease of epidemic magnitude. Little is known about the predictors of depression in this population, especially among the Indian population. This study explores the predictors for depression in patients with type 2 DM.

MATERIALS AND METHODS

A cross-sectional study was performed for a period of 7 months during 2018-2019. The data were collected from 250 subjects at the diabetic clinic and psychiatry outpatient department of a tertiary care teaching hospital. T2DM with an age group of 18-60 years were included. Exclusion criteria were clinical evidence of any significant Axis I psychiatric disorder according to the International Classification of Diseases-10 Diagnostic Criteria for Research other than depression and substance use disorders. Data were analyzed with multiple linear regression analysis using SPSS-23 version.

RESULTS

Male and female patients were 127 (50.80%) and 123 (49.20%), respectively. The prevalence of depression was 49.20% among 250 patients with T2DM. Female patients had higher depression than male patients. We found age (P = 0.013), female gender (P = 0.041), locality of the patient (P = 0.021), body mass index (BMI) (P = 0.018), and fasting blood sugar (FBS) (P = 0.045) as significant predictors of depression among T2DM patients.

CONCLUSIONS

The study concludes that females and elderly patients were more affected by depression. The predictors of depression were age, gender, locality, BMI, and FBS among diabetic patients. The findings indicate to screen the patients of T2DM for depression, predominantly female and elderly patients, at regular intervals as per clinical demand.

Prevalence of Depressive Symptoms in the Elderly Population Diagnosed with Type 2 Diabetes Mellitus

Introduction: A sharp rise in the population of elderly people, who are more prone to somatic and mental diseases, combined with the high prevalence of type 2 diabetes mellitus and diabetes-associated complications in this age group, have an impact on the prevalence of depressive symptoms. Aim of the work: The work of the study was the evaluation of the prevalence of depressive symptoms in the elderly population diagnosed with type 2 diabetes mellitus. Materials and methods: The pilot study was conducted in 2019 among 200 people diagnosed with type 2 diabetes mellitus, aged 65 years and above, receiving treatment in a specialist diabetes outpatient clinic. The study was based on a questionnaire aimed at collecting basic sociodemographic and clinical data and the complete geriatric depression scale (GDS, by Yesavage) consisting of 30 questions. Results: The study involved 200 patients receiving treatment in a diabetes outpatient clinic. The mean age of the study subjects was 71.4 ± 5.0 years. The vast majority of the subjects (122; 61%) were women, with men accounting for 39% of the study population (78 subjects). A statistically significant difference in the GDS (p < 0.01) was shown for marital status, body mass index (BMI), duration of diabetes, and the number of comorbidities. Patients with results indicative of symptoms of mild and severe depression were found to have higher BMI, longer disease duration, and a greater number of comorbidities. There were no statistically significant differences in the level of HbA1c. Conclusions: In order to verify the presence of depressive symptoms in the group of geriatric patients with diabetes mellitus, an appropriate screening programme must be introduced to identify those at risk and refer them to specialists, so that treatment can be promptly initiated. Screening tests conducted by nurses might help with patient identification.

Association between subthreshold depression and self-care behaviors in people with type 2 diabetes: a systematic review of observational studies

BACKGROUND

Self-care behaviors in people living with type 2 diabetes are important to achieving optimal glycemic control. Major depression in type 2 diabetes is associated with decreased adherence to self-care behaviors. The association between subthreshold depression and self-care behaviors, however, has not previously been systematically reviewed. The objective of this review is to determine the association between subthreshold depression and self-care behaviors.

METHODS

A systematic search was performed in five electronic databases that included MEDLINE, EMBASE, PsycINFO, Emcare, and CINAHL. Any observational studies in adults with type 2 diabetes, investigating the association between subthreshold depression and any self-care behaviors, were included in the review. Qualitative studies, review articles, and gray literature were excluded. Two reviewers independently completed the title and abstract and full-text screening, appraised the study quality, and extracted the data. A third reviewer resolved any discrepancies between the reviewers if needed. Included articles were critically appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist. Meta-analyses were not conducted because criteria for conducting such analyses were not met.

RESULTS

A total of 6408 articles were identified through the database searching. After the abstract and full-text review, two articles met the inclusion criteria. One of the included study was cross-sectional while the other was a longitudinal study. Both studies showed inconsistent findings in the association between subthreshold depression and self-care behaviors. Important risks of bias were identified in the included studies.

DISCUSSION

The evidence from the two included studies on a possible association between subthreshold depression and self-care behaviors in adults with type 2 diabetes was not consistent and potentially biased. Our review established a gap in knowledge and suggests that further high-quality studies are needed to examine the association between subthreshold depression and self-care behaviors in people with type 2 diabetes.
