High prevalence of depressive symptoms in well-controlled adolescents with type 1 diabetes treated with continuous subcutaneous insulin infusion

Comorbidity of Depression and Diabetes: A Literature Review on Systemic Flaws in Healthcare and the Benefits of Collaborative Diagnosis and Treatment in Primary Care Settings

BACKGROUND

The increasing specialization and dispersion of healthcare systems have led to a shortage of resources to address comorbidities. Patients with coexisting mental and physical conditions are disadvantaged, as medical providers often only focus on the patient's mental illness while neglecting their physical needs, resulting in poorer health outcomes.

OBJECTIVE

This study aimed to shed light on the systemic flaws in healthcare systems that contribute to suboptimal health outcomes in individuals with comorbid diseases, including depression and diabetes. This paper also discusses the clinical and economic benefits of collaborative methods for diagnosing and treating depressive disorders in primary care settings.

METHODS

A comprehensive literature review of the relationship between depression and diabetes was conducted. The outcomes of the literature review were carefully analyzed. Several databases were searched using keywords such as "diabetes," "depression," "comorbidity," "prevalence," "epidemiology," and "risk factors" using Google Scholar and PubMed as search engines. The review and research papers written between 1961 and 2023 were our main focus.

RESULTS

This study revealed improved depressive symptoms and better blood sugar and blood pressure control. Additionally, individuals with comorbid depression and diabetes have higher direct and secondary medical costs. Antidepressants and psychological interventions are equally effective in treating depressive symptoms in patients with diabetes, although they have conflicting effects on glycemic control. For individuals with comorbid diabetes and depression, clear care pathways, including a multidisciplinary team, are essential for achieving the best medical and mental health outcomes.

CONCLUSION

Coordinated healthcare solutions are necessary to reduce the burden of illness and improve therapeutic outcomes. Numerous pathophysiological mechanisms interact with one another and may support the comorbidities of T2DM, and depressive disorders could exacerbate the course of both diseases.

Course of screening-based depression in young adults with a long type 1 diabetes duration: Prevalence and transition probabilities - A cohort study

AIMS

To extend the current knowledge of the prevalence and course of screening-based depression (SBD) and its predictors in emerging adults with a long type 1 diabetes duration.

METHODS

A total of 487 young adults (64.7% women, mean age 24.0 years) who participated in a nationwide cohort study provided data on SBD (Patient Health Questionnaire (PHQ-9) score ≥ 10). We estimated the overall and age- and sex-specific prevalence of SBD, identified the associated covariates, and determined the transition probabilities between SBD states using adjusted first-order Markov transition models.

RESULTS

The prevalence of SBD was 17.7% in women and 7.0% in men. A total of 70.4% (95%-CI 57.4%; 80.8%) of the participants with SBD at the first screening still had SBD at the three-year follow-up. Of the subjects without SBD at baseline, 6.9% (4.9%; 9.8%) had SBD at follow-up. The main predictor of current SBD was previous SBD (OR 39.0 (15.4; 98.6)), followed by living in one's own or in a shared apartment vs. living with both parents (OR: 2.75 (1.03; 7.36)).

CONCLUSIONS

Using an innovative analytical approach, emerging adults with a long diabetes duration demonstrated a moderate rate of incident SBD but a high rate of persistent SBD.

High Rate of Depression among Saudi Children with Type 1 Diabetes

Saudi Arabia ranks among the top ten in type 1 diabetes (T1D) prevalence. The psychological burden, including depression, among T1D children, affects short-term and long-term outcomes. In Saudi Arabia, studies on depression among T1D children are limited. We determined the prevalence of depression among T1D children and adolescents in the Saudi Arabia-Qassim region and investigated risk factors for depressive symptoms. This quantitative cross-sectional study was conducted among T1D children and adolescents in the outpatient clinic of Maternity and Children Hospital, Buraydah, Saudi Arabia, between October 2020 and April 2021. Using a validated questionnaire translated into Arabic, we interviewed patients during clinic appointment. Questionnaires on sociodemographic characteristics, clinical data, and Clinical Depression Inventory scale were used to measure depression. There were 148 T1D respondents (children: 58.1%; adolescents: 41.9%). More than half were females (53.4%), with most Saudis (94.6%). Depression prevalence among children and adolescents was 27%. Mild, moderate, and severe depression occurred in 80%, 12.5%, and 7.5% of depressed patients, respectively. Factors significant for depression were female sex (p = 0.014), uncontrolled HbA1c level (p = 0.037), and longer diabetes duration (p = 0.013). Depression among children and adolescents was more prevalent in this study than in previous reports. Early detection of depression will improve diabetes control and quality of life.

Prevalence of diabetes distress and depression and their association with glycemic control in adolescents with type 1 diabetes in Dubai, United Arab Emirates

OBJECTIVE

Diabetes distress and depression have been shown to be prevalent among adolescents with type 1 diabetes and screening for these parameters should be a routine part of diabetes care. To assess the prevalence of diabetes distress and depression and their association with glycemic control in a sample of adolescents with type 1 diabetes attending a diabetes center in Dubai, United Arab Emirates. All adolescents aged 13 to 18 years with type 1 diabetes that were seeking treatment at the Dubai Diabetes Center from the period of September 1, 2018 to May 1, 2019. A total of 72 participants completed the study.

RESEARCH DESIGN AND METHODS

Adolescents were asked to fill in questionnaires assessing diabetes distress and depression. Multivariate linear regression analysis was used to assess the relationships between the subsets of socio-demographic and clinical characteristics, and the scores of the questionnaires.

RESULTS

The mean HbA1c of the study sample was 9.61% [82 mmol/mol] with higher levels found in females as compared with males (p<0.05). Females showed significantly greater levels of distress as compared with males. Although adolescents with HbA1c≥7.5% scored higher for diabetes distress and depression, the difference was not statistically significant to those with an HbA1c of <7.5%. Higher levels of diabetes distress were highly correlated with depressive symptoms, with distress and depression both being significant predictors of one another.

CONCLUSIONS

Our results highlight the importance of implementing and sustaining psycho-educational interventions to aid in alleviating diabetes distress and depression in this subgroup of the population.

Associations of diabetes self-management characteristics, HbA1c, and psychosocial outcomes with depressive symptoms in a contemporary sample of adolescents with type 1 diabetes

AIMS

We sought to examine the associations between diabetes self-management, HbA1c, and psychosocial outcomes with the frequency of depressive symptoms.

METHODS

We surveyed 301 teens (50% male, 22% non-white), mean age of 15.0±1.3 years, diabetes duration of 6.5±3.7 years. Biomedical variables: daily frequency of blood glucose monitoring of 4.5±1.9, 63% insulin pump use, mean HbA1c 8.5±1.1% (69±12 mmol/mol); 15% of the sample achieved the target HbA1c of <7.5% (<58 mmol/mol).

RESULTS

Nearly 1 in 5 (18%, n=54) adolescents reported significant depressive symptoms and, of those participants, slightly under half reported moderate/severe depressive symptoms. Teens with moderate/severe depressive symptoms (CES-D scores ≥24) were more likely to be female, have parents without a college education, and not utilize insulin pumps. Teens with more depressive symptoms reported higher diabetes family conflict, higher diabetes burden, and lower quality of life. In the group reporting no depressive symptoms (10%), scores on psychosocial variables and diabetes treatment variables were the most favorable.

CONCLUSION

In our sample, the presence of depressive symptoms appears to relate to both diabetes treatment and quality of life. In addition, studying teens without depressive symptoms can help us learn more about protective factors that potentially buffer against depressive symptoms and that are associated with better outcomes.

Psychosocial Aspects of Diabetes Technology Use: The Child and Family Perspective

This article offers a systematic review of the literature on psychosocial aspects of technology use in children and adolescents with type 1 diabetes and their families, searching for relevant articles published the past 5 years. Topics included continuous subcutaneous insulin infusion, continuous glucose monitoring, predictive low-glucose suspend, and artificial pancreas systems. The review indicates there are positive and negative psychosocial aspects to diabetes technology use among youth and their families. Although consistent findings were revealed, contradictions exist. Discussed are recommendations for future research and implications for how health care providers can collaborate with families to discuss and manage diabetes technology.

Depression Screening of Adolescents With Diabetes: 5-Years of Implementation and Outcomes

As part of a quality improvement (QI) initiative, Cincinnati Children's Hospital Diabetes Center established a model of reliable, feasible, routine depression screening in a subspecialty clinic for adolescents with diabetes.¹ On the occasion of the special section of the journal focusing on screening for, detection of, and treatment of depression in diverse settings, the purpose of this correspondence is to describe the evolution of an in-clinic, pragmatic approach to depression and suicidal ideation (SI) screening, and to evaluate depression screening scores and glycemic control across age groups over time.

Mealtime insulin bolus adherence and glycemic control in adolescents on insulin pump therapy

Poor self-management contributes to insufficient glycemic control in adolescents with type 1 diabetes (T1DM). We assessed the effects on glycemic control of adherence to self-measurement of blood glucose (SMBG) and insulin boluses in 90 adolescents with T1DM on insulin pump therapy over a 2-month period. We compared the number of insulin boluses and SMBGs around main meals to the "gold standard" of optimal diabetes management (SMBGs and a bolus before each main meal and SMBG before bedtime). The mean (95% CI) HbA1c levels were 2.9(1.7 to 4.0) mmol/mol lower for every additional insulin bolus and 3.1(1.6 to 4.5) mmol/mol lower for every additional SMBG. Patients performing SMBG and bolusing around each main meal had considerably lower HbA1c levels than those unable to do (95% CI for difference 4.3 to 10.4 mmol/mol and 11.5 to 20.1 mmol/mol respectively). For each additional mealtime bolus/day, the odds ratio of achieving target HbA1c levels of <58 mmol/mol was 6.73 (95% CI 2.94-15.38), after adjustment for gender, age, diabetes duration, and affective responses to SMBG in a multiple logistic regression model.Conclusion: Glycemic control in adolescents with T1DM on insulin pump therapy is strongly dependent on adherence to insulin boluses around mealtimes. What is Known: • In mixed groups of children and adolescents, insulin bolus frequency and self-monitoring of blood glucose (SMBG) frequency were determinants of HbA1c levels. • Adherence to insulin boluses and SMBG is particularly challenging in adolescents. What is New: • In adolescents on insulin pump therapy, each additional insulin bolus, particularly around mealtime, was significantly associated with approximately 3 mmol/mol lower HbA1c levels. • This beneficial effect of mealtime bolusing was strongest for the evening meal.

A systematic review of non-genetic predictors and genetic factors of glycated haemoglobin in type 1 diabetes one year after diagnosis

Type 1 diabetes (T1D) results from autoimmune destruction of the pancreatic βcells. Although all T1D patients require daily administration of exogenous insulin, their insulin requirement to achieve good glycaemic control may vary significantly. Glycated haemoglobin (HbA1c) level represents a stable indicator of glycaemic control and is a reliable predictor of long-term complications of T1D. The purpose of this article is to systematically review the role of non-genetic predictors and genetic factors of HbA1c level in T1D patients after the first year of T1D, to exclude the honeymoon period. A total of 1974 articles published since January 2011 were identified and 78 were finally included in the analysis of non-genetic predictors. For genetic factors, a total of 277 articles were identified and 14 were included. The most significantly associated factors with HbA1c level are demographic (age, ethnicity, and socioeconomic status), personal (family characteristics, parental care, psychological traits...) and features related to T1D (duration of T1D, adherence to treatment …). Only a few studies have searched for genetic factors influencing HbA1c level, most of which focused on candidate genes using classical genetic statistical methods, with generally limited power and incomplete adjustment for confounding factors and multiple testing. Our review shows the complexity of explaining HbA1c level variations, which involves numerous correlated predictors. Overall, our review underlines the lack of studies investigating jointly genetic and non-genetic factors and their interactions to better understand factors influencing glycaemic control for T1D patients.

Depressive Symptoms at Critical Times in Youth With Type 1 Diabetes: Following Type 1 Diabetes Diagnosis and Insulin Pump Initiation

PURPOSE

Depressive symptoms occur at various times during the life cycle in persons with type 1 diabetes. We investigated depressive symptoms prospectively in youth with new-onset type 1 diabetes and in those beginning pump therapy.

METHODS

Youth with type 1 diabetes (N = 96), ages 10-17 years, completed the Children's Depression Inventory (CDI) at baseline and at 1, 6, and 12 months after diabetes onset or pump start; scores ≥13 indicated clinical elevation. The change in depressive symptoms and the association between CDI score and hemoglobin A1c (HbA1c) level were assessed over 1 year.

RESULTS

The new-onset group (n = 54) had an HbA1c level of 11.4% ± 2.5%. The pump group (n = 42) had a diabetes duration of 4.1 ± 3.4 years and an HbA1c level of 8.3% ± 1.3%. The baseline median CDI was 5.0 in both groups and remained low over time (ranging from 2.0 to 3.5). Most youth (new onset 72%, pump 81%) scored <13 at all times. Those with a CDI score of ≥13 in month 1 had 9-fold (95% confidence interval: 3-28) and 11-fold (95% confidence interval: 3-38) higher risks of CDI score of ≥13 at 6 and 12 months, respectively, than those with a CDI score of <13. New-onset youth with a CDI score of ≥13 in month 1 had a higher HbA1c level at 6 months (8.3% ± 1.7%) than new-onset youth with a CDI score of <13 (7.2% ± 1.6%, p = .04).

CONCLUSIONS

CDI scores over 1 year were similar in the new-onset and pump groups. Youth with elevated CDI in the first month after diagnosis or pump start were significantly more likely to have a CDI score of ≥13 at 6 or 12 months, supporting recommendations to screen for depressive symptoms because of persistence over time. Those with new-onset diabetes and depressive symptoms in the first month had higher HbA1c at 6 months; confirmatory research is needed.

Prevalence of depression and depressive symptoms among outpatients: a systematic review and meta-analysis

OBJECTIVES

Depression and depressive symptoms are common mental disorders that have a considerable effect on patients' health-related quality of life and satisfaction with medical care, but the prevalence of these conditions varies substantially between published studies. The aim of this study is to conduct a systematic review and meta-analysis to provide a precise estimate of the prevalence of depression or depressive symptoms among outpatients in different clinical specialties.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES AND ELIGIBILITY CRITERIA

The PubMed and PsycINFO, EMBASE and Cochrane Library databases were searched to identify observational studies that contained information on the prevalence of depression and depressive symptoms in outpatients. All studies included were published before January 2016. Data characteristics were extracted independently by two investigators. The point prevalence of depression or depressive symptoms was measured using validated self-report questionnaires or structured interviews. Assessments were pooled using a random-effects model. Differences in study-level characteristics were estimated by meta-regression analysis. Heterogeneity was assessed using standard χ² tests and the I² statistic. The study protocol has been registered with PROSPERO under number CRD42017054738.

RESULTS

Eighty-three cross-sectional studies involving 41 344 individuals were included in this study. The overall pooled prevalence of depression or depressive symptoms was 27.0% (10 943/41 344 individuals; 95% CI 24.0% to 29.0%), with significant heterogeneity between studies (p<0.0001, τ²=0.3742, I²=96.7%). Notably, a significantly higher prevalence of depression and depressive symptoms was observed in outpatients than in the healthy controls (OR 3.16, 95% CI 2.66 to 3.76, I²=72.0%, χ ² =25.33). The highest depression/depressive symptom prevalence estimates occurred in studies of outpatients from otolaryngology clinics (53.0%), followed by dermatology clinics (39.0%) and neurology clinics (35.0%). Subgroup analyses showed that the prevalence of depression and depressive symptoms in different specialties varied from 17.0% to 53.0%. The prevalence of depression and depressive symptoms was higher among outpatients in developing countries than in outpatients from developed countries. Moreover, the prevalence of depression and depressive symptoms in outpatients slightly decreased from 1996 to 2010. Regarding screening instruments, the Beck Depression Inventory led to a higher estimate of the prevalence of depression and depressive symptoms (1316/4702, 36.0%, 95% CI 29.0% to 44.0%, I²=94.8%) than the Hospital Anxiety and Depression Scale (1003/2025, 22.0%, 95% CI 12.0% to 35.0%, I²=96.6%).

CONCLUSION

Our study provides evidence that a significant proportion of outpatients experience depression or depressive symptoms, highlighting the importance of developing effective management strategies for the early identification and treatment of these conditions among outpatients in clinical practice. The substantial heterogeneity between studies was not fully explained by the variables examined.

The link between depression and diabetes: the search for shared mechanisms

Depression is twice as common in people with type 1 or type 2 diabetes as in the general population, and is associated with poor outcomes. Evidence is growing that depression and type 2 diabetes share biological origins, particularly overactivation of innate immunity leading to a cytokine-mediated inflammatory response, and potentially through dysregulation of the hypothalamic-pituitary-adrenal axis. Throughout the life course, these pathways can lead to insulin resistance, cardiovascular disease, depression, increased risk of type 2 diabetes, and increased mortality. Proinflammatory cytokines might directly affect the brain, causing depressive symptoms. In type 1 diabetes, mediators of depression are not well studied, with research hindered by inconsistent definitions of depression and scarcity of observational, mechanistic, and interventional research along the life course. Despite few studies, evidence suggests that familial relationships and burden of a lifelong disorder with an onset early in personality development might contribute to increased vulnerability to depression. Overall, longitudinal research is needed to identify risk factors and mechanisms for depression in patients with diabetes, particularly early in the life course. Ultimately, improved understanding of shared origins of depression and diabetes could provide the potential to treat and improve outcomes of both disorders simultaneously. These shared origins are targets for primary prevention of type 2 diabetes.
