Association and Familial Coaggregation of Type 1 Diabetes and Eating Disorders: A Register-Based Cohort Study in Denmark and Sweden

Disordered eating behaviors and associated factors in children and adolescents with type 1 diabetes

OBJECT

As part of their treatment, patients with type 1 diabetes mellitus (DM) have to be very careful with what they eat and with their insulin doses. Therefore, the risk of eating disorders increases in this patient group. In this study, we aimed to determine the disordered eating behaviors of patients with type 1 DM and to evaluate the sociodemographic characteristics, diabetes care behaviors, and quality-of-life scale results that these behaviors may be related to.

METHOD

The sociodemographic characteristics and diabetes treatment data of 191 patients aged 9-18 years with type 1 DM were analyzed. The Pediatric Quality of Life Inventory (PedsQL), the PedsQL 3.0 Diabetes Module, and the Diabetes Eating Problem Survey-Revised (DEPS-R) were applied.

RESULTS

The median DEPS-R score of the patients was 18 (19.00), and 44.5 % had a DEPS-R score above 20. A significant correlation was found between age, duration of diabetes, frequency of blood glucose measurement, hemoglobin A1c (HbA1c) level, body mass index standard deviation score (BMI-SDS), and DEPS-R score. There was no significant difference between girls and boys. Patients with a high DEPS-R score had low scores on the PedsQL and on the PedsQL 3.0 Diabetes Module.

CONCLUSION

The DEPS-R scale is a diabetes-specific, easy-to-use, and effective method for screening patients with type 1 DM for disordered eating behaviors. It can help prevent the progression of disordered eating behaviors to clinical eating disorders in patients with type 1 DM. It would be beneficial to use this scale as a routine screening, especially in clinics where access to a psychologist is not possible.

Mechanisms underlying the development of eating disorders and disordered eating in adolescent females with type 1 diabetes

OBJECTIVE

People with Type 1 diabetes (T1D) face an increased risk of eating disorders/disordered eating (ED/DE), with adolescents being particularly vulnerable. Empirical knowledge on the mechanisms underlying development of ED/DE in T1D is crucial for evolving prevention strategies.

RESEARCH DESIGN AND METHODS

Fourteen semi-structured interviews with adolescent females with T1D and ED/DE between 14 and 18 years were conducted and analyzed using reflexive thematic analysis.

RESULTS

Analyses identified four main themes; 'Interconnected afflictions', 'Judgment', 'Feeling Different', and 'Chaos & Control', These themes explore the interconnectedness of T1D and ED/DE, with shame and guilt emerging as common underlying mechanism. The development of a biopsychosocial model was based on the integration of these data with existing models.

CONCLUSIONS

The study extends previous developmental pathways of ED/DE in adolescents with T1D. We propose a biopsychosocial model that incorporates various factors: predisposing factors such as parental management of T1D and weight gain during adolescence; precipitating factors including comments on weight, frequency of weighing, perceptions of surveillance; the perpetuating bilateral influence of ED/DE and T1D and finally highlighting the protective mechanisms of disease acceptance encompassing parental handling of diagnosis and the contribution of healthcare professionals (HCP's) role in psychoeducation. The present study highlight the vulnerability of adolescence in the presence of T1D, particularly concerning issues related to eating, weight, and body. It offers clinically relevant insights, with the aim to improve communication and management strategies for this very specific group.

Profiles of disordered eating behaviour in type 1 diabetes using the DEPS-R and behaviour and glycaemic outcomes in a real-life setting

AIMS

The Diabetes Eating Problems Survey - Revised (DEPS-R) is commonly used to assess disordered eating behaviour (DEB) in individuals with type 1 diabetes and has advantages compared to other measures not specifically tailored to diabetes. A score ≥20 on the DEPS-R is used to indicate clinically significant DEB; however, it does not distinguish between eating disorder (ED) phenotypes necessary to guide treatment decisions, limiting clinical utility.

METHODS

The current study used latent class analysis to identify distinct person-centred profiles of DEB in adults with type 1 diabetes using the DEPS-R. Analysis of Variance with Games Howell post-hoc comparisons was then conducted to examine the correspondence between the profiles and binge eating, insulin restriction and glycaemic control (HbA1c, mean blood glucose, and percent time spent in hyperglycaemia) during 3 days of assessment in a real-life setting.

RESULTS

Latent class analysis indicated a 4-class solution, with patterns of item endorsement suggesting the following profiles: Bulimia, Binge Eating, Overeating and Low Pathology. Differences in binge eating, insulin restriction and glycaemic control were observed between profiles during 3 days of at-home assessment. The Bulimia profile was associated with highest HbA1c and 3-day mean blood glucose.

CONCLUSIONS

There are common patterns of responses on the DEPS-R that appear to reflect different ED phenotypes. Profiles based on the DEPS-R corresponded with behaviour in the real-life setting as expected and were associated with different glycaemic outcomes. Results may have implications for the use of the DEPS-R in research and clinical settings.

Inpatient admissions and mortality of anorexia nervosa patients according to their preceding psychiatric and somatic diagnoses

OBJECTIVE

Anorexia nervosa (AN) is associated with increased risk of mortality, but little is known about the risk of inpatient admissions and mortality outcomes in individuals with diagnoses of both AN and other psychiatric and somatic conditions. We aimed to investigate the inpatient admissions and mortality among people with AN and other diagnosed conditions using Danish national registers.

METHOD

This retrospective cohort study included individuals diagnosed with AN in Denmark, born 1977-2010. We identified other mental and somatic conditions in this population. We used Cox proportional hazards regression to estimate the risk of inpatient admission and mortality, focusing on (i) the number of other diagnosed conditions, and (ii) specific combinations of conditions diagnosed prior to the AN diagnosis. Categories of inpatient admissions considered were due to: (i) AN, (ii) any psychiatric disorder, and (iii) any somatic disorder. Additionally, competing risks survival analysis was used to calculate the cumulative incidence of inpatient admission and all-cause mortality over the follow-up period.

RESULTS

The study population included 11,489 individuals. The most common conditions individuals had prior to their AN diagnosis were other eating disorders (34.5%) and anxiety disorders (32.7%). During the follow-up, 3184 (27.7%), 4604 (40.1%), and 6636 (57.8%) individuals were admitted for AN, any psychiatric disorder, and any somatic disorder, respectively; and in total 106 (0.9%) died. The risk of all outcomes was highest among those who had received a higher number of other diagnoses. For most combinations, the risks of admission and mortality were increased.

DISCUSSION

Our study presents the prevalence of other conditions in patients with AN in Denmark and elucidates their association with higher rates of inpatient admission and mortality. Our findings highlight the need for comprehensive, multidisciplinary care of patients with AN considering the spectrum of other diagnosed conditions to improve health outcomes.

Obtaining long-term recovery: advances in optimizing treatment outcomes in patients with binge-eating disorder

INTRODUCTION

Binge-eating disorder (BED) is a complex and disabling eating disorder (ED) associated with considerable burden and impairments in quality of life and physical/mental health. It has been recognized as a formal ED category since 2013, however BED is still underdetected and undertreated.

AREAS COVERED

This review summarizes the advances in the understanding of the pathophysiology of BED as well as the evidence on the efficacy of the existing treatments. The authors searched Scopus, PubMed, ClinicalTrials.Gov, and ANZCTR with terms including 'assessment' OR 'treatment' OR 'diagnosis' OR 'mechanisms' AND 'binge eating' OR 'binge-eating disorder' for manuscripts published between January 2013 and April 2023.

EXPERT OPINION

Most of the trials on treatments of BED have been in people of high weight with weight loss as an outcome. Nevertheless, less is known about the treatment of this condition in people with body mass index (BMI) within the normal range where weight stabilization may be a more appropriate goal. Moreover, there is a need for an enhanced appreciation of the role of combination treatment to improve overall outcomes. Also, there are important opportunities for future research in understanding the mechanisms of action and effectiveness of BED treatments.

A Risk Profile for Disordered Eating Behaviors in Adolescents with Type 1 Diabetes: A Latent Class Analysis Study

(1) Background: This multi-center study aimed to identify a risk profile for disordered eating behaviors (DEBs) in youth with type 1 diabetes (T1D) based on their dietary intake, lipid profile, body mass index (BMI-SDS), and glycometabolic control. (2) Methods: Adolescents aged 11 to 18 years from five centers across Italy were recruited. Lipid profile, HbA1c, BMI-SDS, and dietary intake data were collected. The risk for developing DEBs was assessed via the Diabetes Eating Problems Survey-R (DEPS-R) questionnaire. A latent class analysis (LCA) was performed using a person-centered approach. (3) Results: Overall, 148 participants aged 11–18 (12.1, ±3.34), 52% males with a mean diabetes duration of 7.2 (±3.4), were enrolled. Based on the results of the DEBS-R score, LCA allowed us to highlight two different classes of patients which were defined as “at-risk” and “not at-risk” for DEB. The risk profile for developing DEBs is characterized by higher BMI—SDS (23.9 vs. 18.6), higher HbA1c (7.9 vs. 7.1%), higher LDL cholesterol (99.9 vs. 88.8 mg/dL), lower HDL cholesterol (57.9 vs. 61.3 mg/dL), higher proteins (18.2 vs. 16.1%), and lower carbohydrates (43.9 vs. 45.3%). Adolescents included in the “at-risk” class were significantly older (p = 0.000), and their parents’ SES was significantly lower (p = 0.041). (4) Conclusions: This study allowed us to characterize a risk profile for DEBs based on dietary behavior and clinical parameters. Early identification of the risk for DEBs allows timely intervention and prevention of behavior disorders.

Patients' perspectives on screening for disordered eating among adolescents with type 1 diabetes

PURPOSE

People with type 1 diabetes have an increased risk of disordered eating (DE) and eating disorders (ED). Screening is recommended however little is known about patients' perspectives on screening questionnaires. This paper reports qualitative analyses of patients' perspectives on the questionnaire Diabetes Eating Problem Survey Revised (DEPS-R), including acceptability, attitudes, and cognitive understanding.

RESEARCH DESIGN AND METHODS

15 adolescents with type 1 diabetes between 11 and 18 years, were interviewed. A semi-structured format and a qualitative Interpretive Descriptive (ID) methodology was chosen.

RESULTS

The analyses identified four themes: (1) The Questionnaire, (2) Reframing Diabetes Visits, (3) This is (not) for me, and (4) Out in the Open. The DEPS-R was completed with-in 5-10 min. with no technical difficulties. The questionnaire altered the diabetes visit for some, creating a new dialog, and time for self-reflection. Adolescents appreciated the direct approach in the questionnaire, and showed willingness to complete the questionnaire, when presented to them by a health care professional (HCP). One item in the DEPS-R proved difficult to understand for some participants.

CONCLUSION

The study highlights DEPS-R as a clinically relevant screening questionnaire. Completing DEPS-R prior to a consultation opens the door to a consultation that invites the adolescent to address matters of eating behavior. Our findings suggest that systematic screening of DE/ED using the DEPS-R is both accepted and welcomed by adolescents with type 1 diabetes. Future research should focus on a potential update of selected items in DEPS-R.

Eating Disorders and Metabolic Diseases

Eating disorders are complex diseases with multifactorial causes. According to the Diagnostic and Statistical Manual of Mental Disorders text version (DSM-5-TR) and the WHO International Classification of Diseases and Related Health Problems (ICD-11), the major types of eating disorders include anorexia nervosa, bulimia nervosa, and binge eating disorder. The prevalence of eating disorders is alarmingly increasing globally. Moreover, the COVID-19 pandemic has led to more development and worsening of eating disorders. Patients with eating disorders exhibit high rates of psychiatric comorbidities and medical comorbidities such as obesity, diabetes, and metabolic syndrome. This paper aims to review and discuss the comorbidities of eating disorders with those metabolic diseases. Eating disorder treatment typically includes a combination of some or all approaches such as psychotherapy, nutrition education, and medications. Early detection and intervention are important for the treatment of eating disorders.

Association and Familial Coaggregation of Childhood-Onset Type 1 Diabetes With Depression, Anxiety, and Stress-Related Disorders: A Population-Based Cohort Study

OBJECTIVE

To estimate the association and familial coaggregation of childhood-onset type 1 diabetes with depression, anxiety, and stress-related disorders.

RESEARCH DESIGN AND METHODS

This was a population-based cohort study with use of data from Swedish nationwide registers. A total of ∼3.5 million individuals born in Sweden 1973-2007 were linked to their biological parents, full siblings and half-siblings, and cousins. Cox models were used to estimate the association and familial coaggregation of type 1 diabetes with depression, anxiety, and stress-related disorders.

RESULTS

Individuals diagnosed with childhood-onset type 1 diabetes (n = 20,005) were found to be at greater risks of all outcomes: any psychiatric diagnosis (adjusted hazard ratio [aHR] 1.66 [95% CI 1.59-1.72]) or specific diagnoses of depression (1.85 [1.76-1.94]), anxiety (1.41[1.33-1.50]), and stress-related disorders (1.75 [1.62-1.89]), as well as use of antidepressants or anxiolytics (1.30 [1.26-1.34]), compared with individuals without type 1 diabetes. Overall, relatives of individuals with type 1 diabetes were at elevated risks of developing these outcomes, with the highest risks seen in parents (aHRs 1.18-1.25), followed by full siblings (aHRs 1.05-1.20), and the magnitudes of risk estimates appear proportional to familial relatedness.

CONCLUSIONS

These results support existing evidence that children and adolescents with type 1 diabetes are at greater risks of developing depression, anxiety, and stress-related disorders and indicate that shared familial factors might contribute to these elevated risks. Our findings highlight the need for psychological consulting for children and their families in diabetes care. Quantitative and molecular genetic studies are warranted to further understand the etiology of these psychiatric disorders in type 1 diabetes.

Binge eating disorder

Binge eating disorder (BED) is characterized by regular binge eating episodes during which individuals ingest comparably large amounts of food and experience loss of control over their eating behaviour. The worldwide prevalence of BED for the years 2018-2020 is estimated to be 0.6-1.8% in adult women and 0.3-0.7% in adult men. BED is commonly associated with obesity and with somatic and mental health comorbidities. People with BED experience considerable burden and impairments in quality of life, and, at the same time, BED often goes undetected and untreated. The aetiology of BED is complex, including genetic and environmental factors as well as neuroendocrinological and neurobiological contributions. Neurobiological findings highlight impairments in reward processing, inhibitory control and emotion regulation in people with BED, and these neurobiological domains are targets for emerging treatment approaches. Psychotherapy is the first-line treatment for BED. Recognition and research on BED has increased since its inclusion into DSM-5; however, continuing efforts are needed to understand underlying mechanisms of BED and to improve prevention and treatment outcomes for this disorder. These efforts should also include screening, identification and implementation of evidence-based interventions in routine clinical practice settings such as primary care and mental health outpatient clinics.

Obsessed with Healthy Eating: A Systematic Review of Observational Studies Assessing Orthorexia Nervosa in Patients with Diabetes Mellitus

Orthorexia nervosa (ON) is an unspecified feeding or eating disorder (USFED) characterized by an exaggerated, unhealthy obsession with healthy eating. Τypical eating disorders (EDs) and USFEDs are common among patients with diabetes mellitus (DM), which complicates metabolic control and disease outcomes. The present systematic review summarizes the evidence on the prevalence of ON symptomatology among patients with DM. PubMed, Web of Science, Scopus, and grey literature were searched, and relevant observational studies were screened using the Rayyan software. The quality of the studies was assessed using the appraisal tool for cross-sectional studies (AXIS) and the Newcastle-Ottawa scale (NOS). Out of 4642 studies, 6 fulfilled the predefined criteria and were included in the qualitative synthesis. Most studies relied on the ORTO-15 or its adaptations to identify ON among patients with DM. No apparent sex or age differences exist regarding the prevalence of ON symptoms. None of the studies compared the prevalence of ON in patients with type 1 and type 2 DM. Most of the research was of average to good methodological quality. In conclusion, patients with DM often exhibit ON tendencies, although research is still limited regarding the etiology or mechanistic drivers behind ON and the characteristics of patients with a dual ON-DM diagnosis.
