Clinical characteristics and outcome of 467 patients with a clinically recognized eating disorder identified among 52,215 patients with type 1 diabetes: a multicenter german/austrian study

Prevalence of eating disorder symptoms in people with insulin-dependent-diabetes: A systematic review and meta-analysis

AIMS

To examine the prevalence of eating disorder symptoms (EDS) in 16 years and older individuals with insulin-dependent diabetes including both clinical and subclinical eating disorder symptoms.

METHODS

We searched PubMed, Embase, Scopus, PsycINFO, and CINAHL databases to discover studies reporting prevalence of eating disorder symptoms in patients with insulin-dependent diabetes (both type 1 and type 2). We performed a meta-analysis to estimate the pooled prevalence of eating disorder symptoms and an independent meta-analysis to estimate the prevalence of insulin omission.

RESULTS

A total of 45 studies were included in the meta-analysis of eating disorder symptoms. Diabetes Eating Problem Survey (DEPS-R) was the most frequently used screening tool (in 43 % of studies, n = 20). The pooled prevalence of eating disorder symptoms was 24 % (95 % CI 0.21-0.28), whereas in studies using DEPS-R, it was slightly higher, 27 % (95 % CI 0.24-0.31), with the prevalence ratio (PR) of 1.1. The prevalence differed between screening tools (χ2 = 85.83, df = 8, p < .0001). The sex distribution was associated with the observed prevalences; in studies with a higher female prevalence (>58 %), the pooled eating disorder symptom prevalence was higher [30 % (95 % CI 0.26-0.34) vs. 18 % (95 % Cl 0.14-0.22), PR 1.7]. The prevalence of insulin omission was 21 % (95 % CI 0.13-0.33).

CONCLUSIONS

Eating disorder symptoms and insulin omission are common in patients with insulin-dependent diabetes regardless of age. DEPS-R is the most used screening tool. Studies with a higher proportion of female participants report higher prevalence rates.

Diabulimia: A Risky Trend Among Adults with Type 1 Diabetes Mellitus

OBJECTIVE

Poor adherence leads to worse glycemic control and increased complications in patients with type 1 diabetes mellitus (T1DM). Diabulimia characterizes patients with T1DM who skip or use less insulin for weight loss purposes. The study objectives were to determine: (1) the prevalence of diabulimia among adult patients with T1DM, (2) compare patients with and without diabulimia, and (3) identify factors that may place individuals at higher risk of diabulimia.

METHODS

A 40-item, web-based survey was administered to 21 T1DM discussion boards, Listservs, and social media outlets. The survey assessed demographics, diabetes management, psychiatric diagnoses, and screened for diabulimia. Individuals who reported intentionally skipping or using less insulin than directed for the purpose of weight loss or to prevent weight gain in the past 12 months were classified as having diabulimia.

RESULTS

Of the 225 participants who completed the survey, 8.9% had diabulimia. Patients with diabulimia had elevated hemoglobin A1C (A1C) levels (8.4% vs 6.9%; P = .014), higher rates of a diabetes-related emergency department visits or hospitalization (30.0% vs 13.2%; P = .042), and higher rates of a major depressive disorder diagnosis (40.0% vs 11.5%; P < .001) than patients without diabulimia. Factors associated with diabulimia included high A1C levels (odds ratio, 1.43; 95% CI [1.08-1.91]; P = .014) and a major depressive disorder diagnosis (odds ratio, 4.87; 95% CI [1.31-18.22]; P = .018).

CONCLUSION

Approximately 1 in 11 adult patients with T1DM screened positive for diabulimia. Higher A1C levels and a diagnosis of major depressive disorder were associated with diabulimia.

Prevalence and Multidimensional Model of Disordered Eating in Youths With Type 1 Diabetes: Results From a Nationwide Population-Based Study

OBJECTIVE

The aim of this study was to report nationwide data of the prevalence of disordered eating behaviors (DEBs) in adolescents with type 1 diabetes (T1D) and to evaluate a multidimensional model of eating problems, analyzing how psychopathological problems are associated with DEBs and with metabolic control.

METHODS

This study was carried out using a cross-sectional design with a sample of 1,562 patients with T1D (812 male), aged 11-19 years. Participants were recruited from multiple pediatric diabetes centers (N = 30) located in northern, central, and southern Italy, and they individually completed the Diabetes Eating Problem Survey-Revised (DEPS-r) and the Youth Self-Report (YSR). Sociodemographic and clinical data were also gathered. Multiple-group structural equation modeling was used to investigate the relationships between internalizing/externalizing symptoms, DEBs, and glycosylated hemoglobin (HbA1c) values.

RESULTS

A total of 29.7% of the participants reported DEBs (DEPS-r scores ≥20), 42.4% reported insulin manipulation (IM). The prevalence of DEBs was higher for female participants (p ≤ .001). The model explains 37% of the variance in disordered eating, 12% in IM, and 21% in HbA1c values. Body mass index, externalizing symptoms, and internalizing symptoms were significantly and positively associated with DEBs, which in turn were significantly and positively associated with HbA1c values (all p ≤ .001). Externalizing (p ≤ .001) and internalizing (p ≤ .01) symptoms were also directly associated with HbA1c values.

CONCLUSION

Given the relevant prevalence of DEBs, their significant positive association with psychopathological symptoms, and their relationship with worse diabetes outcomes, regular psychological screening and support is needed to ensure the best care of adolescents with T1D.

Characteristics of carbohydrate counting practice associated with adequacy of glycated hemoglobin in adults with type 1 diabetes mellitus in Brazil

Background

The Carbohydrate Counting (CC) is directly associated with achieving glycemic control by people with Type 1 Diabetes Mellitus (T1DM). Therefore, this study aims to analyze characteristics of the CC practice associated with the adequacy of glycated hemoglobin (HbA1c) in adults with T1DM in Brazil.

Methods

The study was cross-sectional, carried out using an online form with questions about knowledge of CC, clinical, anthropometric, sociodemographic data, follow-up with health professionals and understanding of the concepts of CC. Pearson's chi-square test and binomial logistic regression analysis (p<0.05) were applied.

Results

173 adults participated, of which 57.2% had increased HbA1c (≥7%). Having the diabetes duration <10 years (p=0.006), performing the CC at lunch (p=0.040) and dinner (p=0.018), using specific applications to perform the CC (p=0.001), having learned to perform CC with a nutritionist (p=0.037) and knowing how to correctly define the concepts of food bolus (p=0.001), correction bolus (p<0.001) and insulin/carbohydrate ratio (p<0.001) was associated with having adequate HbA1c (<7%). Participants who were undergoing CC practice were 3.273 times more likely to have adequate HbA1c and participants with diabetes duration <10 years were 2.686 times more likely to have adequate HbA1c.

Conclusion

It was concluded that variables transversal to CC favor adequate HbA1c values in adults with T1DM and that practicing CC and having a diabetes duration of less than 10 years are predictive factors of having adequate HbA1c.

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.

High prevalence with no gender difference of likely eating disorders in type 1 mellitus diabetes on insulin pump

AIM

The aim of this study was to determine the prevalence of likely eating disorders and insulin misuse in a prospective cohort of adults with type 1 diabetes mellitus (T1DM) treated with insulin pump therapy.

METHODS

This prospective study was held at the participants' home. The participants completed the SCOFF questionnaire as well as a question related to insulin misuse. Information about lifestyle, medical history, insulin pump and Continuous Glucose Monitoring (CGM) data were collected.

RESULTS

The analysis covered 198 participants with a median age of 51 [95% CI 38; 62] years. The prevalence of likely eating disorders was 21.7% (95% CI 16.3; 28.2) in the study population and 20.6% (95% CI 14.3; 28.6) and 24.2% (95% CI 14.6; 37.0) in males and females respectively. The prevalence of insulin misuse was 39.0% (95% CI 30.8; 47.7). There was no significant difference in prevalence between males and females for likely eating disorders and insulin misuse. The analysis of CGM data revealed no factors related to glycaemic control associated with likely eating disorders.

CONCLUSION

The results of this study indicate that the prevalence of likely eating disorders is high even in a middle-aged population with a T1DM and satisfactory glucose control.

Risk factors for eating disorders: findings from a rapid review

BACKGROUND

Risk factors represent a range of complex variables associated with the onset, development, and course of eating disorders. Understanding these risk factors is vital for the refinement of aetiological models, which may inform the development of targeted, evidence-based prevention, early intervention, and treatment programs. This Rapid Review aimed to identify and summarise research studies conducted within the last 12 years, focusing on risk factors associated with eating disorders.

METHODS

The current review forms part of a series of Rapid Reviews to be published in a special issue in the Journal of Eating Disorders, funded by the Australian Government to inform the development of the National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2021, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, or population studies). Data pertaining to risk factors for eating disorders were synthesised and outlined in the current paper.

RESULTS

A total of 284 studies were included. The findings were divided into nine main categories: (1) genetics, (2) gastrointestinal microbiota and autoimmune reactions, (3) childhood and early adolescent exposures, (4) personality traits and comorbid mental health conditions, (5) gender, (6) socio-economic status, (7) ethnic minority, (8) body image and social influence, and (9) elite sports. A substantial amount of research exists supporting the role of inherited genetic risk in the development of eating disorders, with biological risk factors, such as the role of gut microbiota in dysregulation of appetite, an area of emerging evidence. Abuse, trauma and childhood obesity are strongly linked to eating disorders, however less conclusive evidence exists regarding developmental factors such as role of in-utero exposure to hormones. Comorbidities between eating disorders and mental health disorders, including personality and mood disorders, have been found to increase the severity of eating disorder symptomatology. Higher education attainment, body image-related factors, and use of appearance-focused social media are also associated with increased risk of eating disorder symptoms.

CONCLUSION

Eating disorders are associated with multiple risk factors. An extensive amount of research has been conducted in the field; however, further studies are required to assess the causal nature of the risk factors identified in the current review. This will assist in understanding the sequelae of eating disorder development and in turn allow for enhancement of existing interventions and ultimately improved outcomes for individuals.

Disordered eating and behaviors among young Egyptians with type 1 diabetes: risk factors and comorbidities

OBJECTIVES

The study aimed to assess occurrence of eating disorders and its nature, associated risk factors, and comorbidities in a cohort of adolescents with type 1 diabetes (T1D).

METHODS

In this cross-sectional study, 138 patients were recruited to complete three questionnaires for assessment of eating disorder (ED); Eating Attitude Test (EAT-26) and Eat Behavior questionnaire (ORTO-15) and Eating Disorder Examination Questionnaire version 6 (EDE-Q6) to assess diabetes-related medical outcomes.

RESULTS

Patients were categorized as having an ED according to predetermined cutoff value for each questionnaire. Of the 138 patients, 24 (17.4%) had risk for EDs by EAT-26 score, 53 (38.4%) have got orthorexia nervosa by ORTO-15 and 45 (32.6%) were having a disordered eating behavior by EDE-Q6. Patients with risk of EDs had lower mean ORTO-15 score (p=0.01), and higher mean Global EDE-Q6 (p<0.001). A positive correlation was found between EAT-26 scores and both age (p<0.0001) and body mass index (p<0.0001). ORTO-15 score was correlated with duration of diabetes (p=0.0418). Diabetic ketoacidosis, peripheral neuropathy, and microalbuminuria occurred frequently in patients with ED high score. Hypoglycemic episodes were reported more in those with high EAT-26 or Global EDE-Q6 scores.

CONCLUSIONS

Subclinical EDs and abnormal eating behaviors are common in Egyptian adolescents with T1D.

Internet-delivered eating disorders prevention program for adolescent girls with type 1 diabetes: Acceptable and feasible

BACKGROUND

Adolescents with type 1 diabetes are at significantly increased risk for eating disorders and few interventions exist.

OBJECTIVE

This study examined the feasibility, acceptability, and preliminary effects of an internet-based eating disorders prevention program adapted specifically for adolescent girls with type 1 diabetes.

PARTICIPANTS AND METHODS

Thirty-five girls (16.2 ± 1.1 years) participated Body Project (T1D Style), a 4-week program consisting of four adolescent sessions focused on promoting illness acceptance, challenging sociocultural body image pressures, increasing social support, and teaching assertive communication. Caregivers participated in one session focused on fostering body image positivity and a healthy relationship with food. Pre-intervention, post-intervention, and 3-month follow-up surveys assessed disordered eating, body dissatisfaction, thin-ideal internalization, diabetes acceptance, diabetes distress, and quality of life. Cohen's d effect sizes were calculated at post-intervention and follow-up. Program acceptability was assessed at post-intervention. Manual fidelity and homework completion were monitored.

RESULTS

High manual fidelity, retention, and homework completion were achieved. Quantitative and qualitative feedback from teens and caregivers suggested high acceptability. Large effects (d = 1.35-0.83) were observed for dieting, body dissatisfaction, diabetes distress, diabetes acceptance, and diabetes-related quality of life at post-intervention, with large-medium effects (d = 1.16-0.58) at follow-up. Medium-small effects (d = 0.49-0.78) at post-intervention were observed for diabetes-specific disordered eating and thin-ideal internalization, with effects maintained at follow-up.

CONCLUSIONS

Results support the acceptability and feasibility of this targeted eating disorders prevention program for adolescent girls with type 1 diabetes. Future clinical trials are warranted to determine its effectiveness compared to a control condition.

The role of mental disorders in precision medicine for diabetes: a narrative review

This narrative review aims to examine the value of addressing mental disorders as part of the care of people with type 1 and type 2 diabetes in terms of four components of precision medicine. First, we review the empirical literature on the role of common mental disorders in the development and outcomes of diabetes (precision prevention and prognostics). We then review interventions that can address mental disorders in individuals with diabetes or at risk of diabetes (precision treatment) and highlight recent studies that have used novel methods to individualise interventions, in person and through applications, based on mental disorders. Additionally, we discuss the use of detailed assessment of mental disorders using, for example, mobile health technologies (precision monitoring). Finally, we discuss future directions in research and practice and challenges to addressing mental disorders as a factor in precision medicine for diabetes. This review shows that several mental disorders are associated with a higher risk of type 2 diabetes and its complications, while there is suggestive evidence indicating that treating some mental disorders could contribute to the prevention of diabetes and improve diabetes outcomes. Using technologically enabled solutions to identify mental disorders could help individuals who stand to benefit from particular treatments. However, there are considerable gaps in knowledge and several challenges to be met before we can stratify treatment recommendations based on mental disorders. Overall, this review demonstrates that addressing mental disorders as a facet of precision medicine could have considerable value for routine diabetes care and has the potential to improve diabetes outcomes.

Disordered eating behaviour and eating disorder among adolescents with type 1 diabetes: An integrative review

BACKGROUND

Type 1 diabetes (DT1) in adolescents brings behavioural changes, altered nutritional habits, and eating disorders.

AIM

To identify and analyze the validated instruments that examine the disordered eating behaviour and eating disorders among adolescents with DT1.

METHODS

An integrative review was accomplished based on the following databases: PubMed, LILACS, CINAHL, Scopus, Web of Science, and Reference Citation Analysis (RCA), including publications in Portuguese, English, or Spanish, without time limit and time published.

RESULTS

The main instruments to evaluate disordered eating behaviour were The Diabetes Eating Problem Survey-Revised, The Diabetes Eating Problem Survey, and the eating attitudes test-26, and for eating disorders the main instruments used were The Bulimic Investigation Test of Edinburgh, The Binge Eating Scale, The Child Eating Disorder Examination, The five questions of the (Sick, Control, One, Fat and Food), and The Mind Youth Questionnaire. These instruments showed an effect in evaluating risks regarding nutritional habits or feeding grievances, with outcomes related to weight control, inadequate use of insulin, and glycaemia unmanageability. We did not identify publication bias.

CONCLUSION

Around the world, the most used scale to study the risk of disordered eating behaviour or eating disorder is The Diabetes Eating Problem Survey-Revised. International researchers use this scale to identify high scores in adolescents with DT1 and a relationship with poorer glycemic control and psychological problems related to body image.

Disordered eating behaviours and eating disorders in adults with type 1 diabetes (DEBBI): rational and design of an observational longitudinal online study

INTRODUCTION

Disordered eating behaviours (DEB) and eating disorders (ED) are among the most common mental health comorbidities of type 1 diabetes. However, research on diabetes-specific risk and protective factors is limited. To this end, comprehensive characterisations of DEB and ED in type 1 diabetes, as well as longitudinal research on the course of DEB and ED, are needed to gain more insight. The 'Disordered eating behaviours and eating disorders in diabetes type I' (DEBBI) study aims to describe DEB/ED and their correlates in people with type 1 diabetes, to identify key diabetes-specific, psychosocial risk and protective factors, and to describe the course of DEB over time.

METHODS AND ANALYSIS

The DEBBI study is a longitudinal online survey with follow-up assessments after 6, 12 and 18 months, targeted at adults who have been diagnosed with type 1 diabetes for at least 12 months. The survey covers data on diabetes diagnosis and self-management (eg, diabetes treatment and complications), lifestyle (eg, eating habits, physical activity), psychosocial well-being (eg, anxiety, depressive symptoms) and demographic and medical information. It includes validated instruments and self-generated items. One key aspect of the data analysis will be latent profile analyses to determine latent subtypes of DEB manifestation in people with type 1 diabetes and their courses over time, including data on the clinical picture and symptoms, behaviours and diabetes-specific complications.

ETHICS AND DISSEMINATION

The study protocol was approved by the Ethics Committee of the State Medical Chamber of Rhineland-Palatine, Germany (ID 2021-16040). Participants give informed written consent before starting the survey. The DEBBI study will provide more clarity in the so far inconsistent empirical evidence base and will help to inform research on prevention and intervention strategies that are tailored to diabetes-specific needs.

TRIAL REGISTRATION NUMBER

The study is registered with DRKS German Clinical Trials Register (DRKS00028833).

Prevalence of disordered eating behaviors in adolescents with type 1 diabetes: Results of multicenter Italian nationwide study

OBJECTIVE

To assess the prevalence of disordered eating behaviors (DEBs) in a large sample of Italian adolescents with type 1 diabetes and to explore potential demographic, clinical, and psychological differences (understood as emotional and behavioral problems) among adolescents with and without DEBs.

METHOD

Adolescents (11-19 years) with type 1 diabetes completed the Diabetes Eating Problems Survey-revised (DEPS-r) and the Youth Self Report (YSR). Demographic and clinical data were also collected.

RESULTS

Of 690 adolescents with type 1 diabetes (mean age 14.97 ± 1.81, n = 337 girls) assessed in this study, 28.1% (21% boys, 35% girls) were DEPS-r positive (score ≥ 20). Girls had higher DEPS-r total scores (p < .0001, d = .42) than boys, although no age differences were found in mean DEPS-r total scores (p = .961). In both genders, adolescents with DEBs had significantly higher zBMI (p < .0001, d = .52) and HbA1c values (p < .0001, d = .54) and showed more emotional and behavioral problems (both as internalizing and externalizing problems) than those without DEBs (all p < .0001). These differences were largely confirmed in all age groups. Adolescents reporting insulin misuse had higher HbA1c values (p = .001, d = .26), higher DEPS-r mean scores (p < .0001, d = 1.07), and greater psychological problems (all p < .001) than those who did not.

DISCUSSION

DEBs are prevalent among adolescents with type 1 diabetes, and those with eating problems showed adverse clinical and psychological conditions. Routine screening for DEBs and of general psychological condition should be a fundamental part of diabetes care, especially during adolescence.

PUBLIC SIGNIFICANCE STATEMENT

This nationwide study indicated that DEBs are common in adolescents with T1D, and those suffering from them show poorer clinical conditions and higher emotional and behavioral problems. As such, it offers important contributions for those working with EDs and in the T1D field, as it provides a deeper understanding of the co-occurring DEBs-emotional/behavioral problems in youths with T1D and highlights the importance of continuous monitoring of their psychological condition by a multidisciplinary team.

Eating disorders and carbohydrate metabolism interrelations

Introduction: Eating disorders are characterised by persistent disturbances in eating behavior, resulting in severe carbohydrate homeostasis changes. The aim of the study is to review mutual correlations between eating disorders, with emphasis on anorexia nervosa, and carbohydrate metabolism, including glycemia and the levels of relevant hormones.

Material and methods: A priori general inclusion criteria were established and included patients with eating disorders or with glucose metabolism disorders. A MEDLINE database review was carried out. Relevant articles have been extracted and approved by supervisor.

Results: 40 studies got included in the review. Patients with active anorexia nervosa display low levels of fasting and postprandial glucose, decreased lipid metabolism, and decreased pancreatic endocrine activity. Insulin levels remain changed even after patient’s re-nourishment – insulin response tends to be delayed and decreased compared to patients without anorexia history. Eating disorders are associated with poorer glycemic control and a higher percentage of diabetic complications in patients with pre-existing diabetes – mostly type I. There are also reports of higher carbohydrate metabolism disturbances among patients with eating disorders.

Conclusions: Carbohydrate metabolism disorders and eating disorders are clearly interrelated, although data on the nature of these relationships are still lacking. Treatment of eating disorders is not possible without normalizing eating patterns, thus also carbohydrate metabolism. However, it is not usual to monitor the mental state in terms of eating disorders potential development in patients during the treatment of carbohydrate disorders. According to existing data, this approach should be changed due to the risk of anorexia nervosa and other eating disorders in this group.

Prevalence of disordered eating in adults with type 1 diabetes in an Australian metropolitan hospital

The purpose of this study is to establish the prevalence of disordered eating behaviours and establish its identifiable factors in adults with T1D attending a large tertiary hospital service. In this cross-sectional study, 199 participants with TID, aged 18-65 years, completed the revised Diabetes Eating Problem Survey-Revised (DEPS-R). Additional demographic and medical data obtained included age, sex, BMI, HbA1C, duration of diabetes and number of hospital admissions within 12 months (including diabetic ketoacidosis). A DEPS-R score of ≥20, indicative of disordered eating behaviour, was evident in 31% of participants. A DEPS-R score of ≥20 was associated with being female (39% females vs. 23.3% males; p = .016) and a high HbA1c (8.9% [7.8-10.2] vs. 8.0% [7.3-8.7], median [IQR], p < .001). The prevalence of disordered eating behaviours increased significantly with BMI, from 21.3% in the healthy BMI group (18.5-24.9 kg/m² ) to 37.1% in the group with BMI > 25 kg/m² (p = .02). A DEPS-R score of ≥20 was often driven by questions related to a desire to lose weight, meal patterns and glycaemic control. While these behaviours may be attributed to desirable self-management behaviours for adults with T1D, the DEPS-R is still a useful tool to identify patients with potential disordered eating behaviours and the need for dietetic intervention.

Socio-cognitive determinants affecting insulin adherence/non-adherence in late adolescents and young adults with type 1 diabetes: a systematic review protocol

Objective

This systematic review aims to investigate the key socio-cognitive determinants associated with adherence/non-adherence to insulin treatment in late adolescents and young adults in the age range of 17–24 years with T1D.

Methods

A pre-specified search strategy will be used to search for studies in the electronic databases and citation indexes: PubMed, EMBASE, Web of Science, and PsycINFO. Two researchers will screen the title and the abstract independently, then will read and critically appraise the full text of each included study. A third independent reviewer will resolve disagreements in data extraction until consensus. Data will be extracted using the Population, Exposure, Outcomes, Study characteristics framework. Study selection will follow the updated guideline for reporting systematic reviews (PRISMA 2020) and will take place from 15 October 2021 to 1 January 2022. The methodological quality and risk of bias of the observational studies will be assessed by the JBI Critical Appraisal Checklist for Cohort and JBI Critical Appraisal Checklist for Analytical Cross Sectional Studies.

Results

A qualitative narrative synthesis will present the characteristics and the quality of studies and the outcomes of concern.

Conclusion

Based on the contemporary literature, this review will synthesize the evidence on the socio-cognitive determinants associated with adherence/non-adherence to insulin treatment in late adolescents and young adults in the age range of 17–24 years with T1D. The findings will help design patient-centered interventions to promote adherence to insulin in this age group, guide patients’ consultations and diabetes self-management education (DSME) programs.

Disordered eating behaviour in adolescents with type 1 diabetes on continuous subcutaneous insulin infusion; relation to body image, depression and glycemic control

BACKGROUND

Disordered eating behaviour (DEB) represents a significant morbidity among people with type-1 diabetes (T1D). Continuous-subcutaneous insulin infusion (CSII) improves glycemic control and psychological wellbeing in those with T1D. However, its relation to DEB remains obscure.

OBJECTIVES

To compare DEB among adolescents with T1D on CSII versus basal-bolus regimen and correlate it with body image, HbA1C and depression.

METHODS

Sixty adolescents with T1D (30 on CSII and 30 on basal-bolus regimen), aged 12-17 years were studied focusing on diabetes-duration, insulin therapy, exercise, socioeconomic standard, hypoglycemic attacks/week and family history of psychiatric illness. Anthropometric measures, HbA1C, binge eating scale (BES), body image tool, patient health questionnaire-9 (PHQ9) and the Mini-KID depression scale were assessed.

RESULTS

Among the studied adolescents with T1D, six had DEB (10%), 14 had poor body-image perception (23.3%), 42 had moderate body-image perception (70%) and 22 had depression (36.7%). Adolescents with T1D on CSII had significantly lower BES (p = 0.022), Mini-KID depression (p = 0.001) and PHQ9 (p = 0.02) than those on basal-bolus regimen. BES was positively correlated to depression (p < 0.001), HbA1C (p = 0.013) and diabetes-duration (p = 0.009) and negatively correlated to body-image (p = 0.003).

CONCLUSION

DEB is a prevalent comorbidity among adolescents with T1D, with higher frequency in those on basal-bolus regimen than CSII.

Personality, Coping and Developmental Conditions in Female Adolescents and Young Adults with Type 1 Diabetes: Influence on Metabolic Control and Quality of Life

Objective

To assess personality factors, coping, developmental conditions and quality of life in female adolescents and young adults with type 1 diabetes (T1D) and high vs.low HbA1c.

Methods

Patients were approached at the Department for Pediatrics, Medical University of Vienna; n = 129 female adolescents (10 to 23 years, mean age 15.21 ± 2.91) with type 1 diabetes were included. HIGH-A1c was defined as HbA1c > 7.5%, LOW-A1c as HbA1c ≤ 7.5% and compared to a sample of 56 age-matched female healthy controls. Self-rating questionnaires were used to assess psychosocial factors: Children's Depression Inventory (CDI); Junior Temperament and Character Inventory (J-TCI); Eating Disorders Inventory-2 (EDI-2); KIDCOPE; Subjective Family Image Test (SFIT) and Inventory of Life Quality in Children and Adolescents(ILC).

Results

T1D patients with HIGH-A1c were younger at the age of diabetes onset, had a longer diabetes duration, a higher maximum BMI, higher depression score, and higher frequency of diabetic ketoacidosis in the last year. They showed significantly higher levels of fatigue, lower levels of taking responsibility, lower ability to set goals and lower self-acceptance, as well as higher levels of ineffectiveness, lower levels of emotional attachment within the family, in particular with the fathers, and used negative coping strategies more often compared to patients with LOW-A1c. Furthermore, they reported significantly higher burden of illness and lower quality of life.

Conclusions

Disadvantageous personality and coping styles as well as developmental conditions should be addressed in the treatment of female adolescents with T1D with management problems.

Angst und Depression bei Typ-1-Diabetes – Erste Ergebnisse des Screenings auf psychische Komorbiditäten bei Jugendlichen und jungen Erwachsenen im Rahmen des COACH-Konsortiums

Die interdisziplinäre Forschungskooperation COACH-Konsortium (Chronic Conditions in Adolescents – Implementation and Evaluation of Patient-centered Collaborative Healthcare) untersucht die psychosoziale Situation von Jugendlichen und jungen Erwachsenen mit chronischen körperlichen Erkrankungen. Zur Untersuchung der psychischen Komorbidität wurden bisher 1.023 Patienten mit Diabetes mellitus Typ 1 im Alter von 12–21 Jahren bei Routinevorstellungen in der Klinik bzw. Ambulanz mittels der Screening-Fragebogen Patient Health Questionnaire (PHQ-9) und Generalized Anxiety Disorder Scale-7 (GAD-7) zu Angst- und Depressionssymptomen befragt. 29,8 % der Jugendlichen und jungen Erwachsenen zeigten ein auffälliges Screening-Ergebnis. Dabei wurden 17,8 % der Fragebogen zu Angstsymptomen und 25,6 % der Fragebogen zu Depressionssymptomen auffällig mit Gesamtscore-Werten ≥ 7 in GAD-7 bzw. PHQ-9 beantwortet. Patienten mit erhöhten Depressions- und Angstwerten wiesen im Mittel einen deutlich höheren medianen HbA1c-Wert als Zeichen einer schlechteren Stoffwechseleinstellung auf (8,33 [8,09; 8,56]) als Patienten mit unauffälligem Screening (7,58 [7,48; 7,68]; p < 0,0001). Angesichts der hohen Prävalenz auffälliger Depressions- und Angstwerte und der Assoziation mit höheren HbA1c-Werten sollte bei allen Jugendlichen mit Diabetes mellitus Typ 1 regelmäßig das Vorliegen psychischer Belastungen abgeklärt werden. Dies könnte eine frühzeitige Diagnose einer psychischen Komorbidität und Intervention ermöglichen. Auf der Basis der Studien im COACH-Projekt können nun evidenzbasierte Empfehlungen für die interdisziplinäre Gesundheitsversorgung von Jugendlichen mit chronischen körperlichen Erkrankungen erstellt werden, die die psychischen Komorbiditäten systematisch berücksichtigen.

Diabetic Ketoacidosis and Mortality in People With Type 1 Diabetes and Eating Disorders

OBJECTIVE

To determine the risk of diabetic ketoacidosis (DKA) and all-cause mortality among adolescents and young adults with type 1 diabetes with and without an eating disorder.

RESEARCH DESIGN AND METHODS

With use of population-level health care administrative data covering the entire population of Ontario, Canada, all people with type 1 diabetes aged 10-39 years as of January 2014 were identified. Individuals with a history of eating disorders were age- and sex-matched 10:1 with individuals without eating disorders. All individuals were followed for 6 years for hospitalization/emergency department visits for DKA and for all-cause mortality.

RESULTS

We studied 168 people with eating disorders and 1,680 age- and sex-matched people without eating disorders. Among adolescents and young adults with type 1 diabetes, 168 (0.8%) had a history of eating disorders. The crude incidence of DKA was 112.5 per 1,000 patient-years in people with eating disorders vs. 30.8 in people without eating disorders. After adjustment for baseline differences, the subdistribution hazard ratio for comparison of people with and without eating disorders was 3.30 (95% CI 2.58-4.23; P < 0.0001). All-cause mortality was 16.0 per 1,000 person-years for people with eating disorders vs. 2.5 for people without eating disorders. The adjusted hazard ratio was 5.80 (95% CI 3.04-11.08; P < 0.0001).

CONCLUSIONS

Adolescents and young adults with type 1 diabetes and eating disorders have more than triple the risk of DKA and nearly sixfold increased risk of death compared with their peers without eating disorders.

From gut microbiota to host appetite: gut microbiota-derived metabolites as key regulators

Feelings of hunger and satiety are the key determinants for maintaining the life of humans and animals. Disturbed appetite control may disrupt the metabolic health of the host and cause various metabolic disorders. A variety of factors have been implicated in appetite control, including gut microbiota, which develop the intricate interactions to manipulate the metabolic requirements and hedonic feelings. Gut microbial metabolites and components act as appetite-related signaling molecules to regulate appetite-related hormone secretion and the immune system, or act directly on hypothalamic neurons. Herein, we summarize the effects of gut microbiota on host appetite and consider the potential molecular mechanisms. Furthermore, we propose that the manipulation of gut microbiota represents a clinical therapeutic potential for lessening the development and consequence of appetite-related disorders.

Prevention and early help for eating disorders in young people with type 1 diabetes

There is building evidence that early intervention is key to improving outcomes in eating disorders, whereas a 'watch and wait' approach that has been commonplace among GPs and other healthcare professionals is now strongly discouraged. Eating disorders occur at approximately twice the rate in individuals with type 1 diabetes compared to the general population. In this group, standard eating disorder treatments have poorer outcomes, and eating disorders result in a particularly high burden of morbidity. Therefore, our first priority must be prevention, with early intervention where disordered eating has already developed. Clinicians working in both eating disorders and diabetes specialist services have highlighted the need for multidisciplinary team collaboration and specific training, as well as improved treatments. We review the current evidence and future directions for prevention, identification and early intervention for eating disorders in children and young people with type 1 diabetes.

Diabetes technologies in people with type 1 diabetes mellitus and disordered eating: A systematic review on continuous subcutaneous insulin infusion, continuous glucose monitoring and automated insulin delivery

AIMS

In this systematic review, we aimed (1) to identify and describe research investigating the use of advanced diabetes technologies (continuous subcutaneous insulin infusion, CSII; continuous glucose monitoring, CGM; automated insulin delivery, AID) in people with type 1 diabetes (T1DM) and disordered eating and (2) to discuss potential (dis)advantages of diabetes technology use in this population, derived from previous research.

METHODS

We conducted a systematic literature search in two electronic databases for English articles published between 2000 and 2020 addressing eating disorders and/or dysfunctional eating behaviours and diabetes technology use in children, adolescents and adults with T1DM (PROSPERO ID CRD42020160244).

RESULTS

Of 70 publications initially identified, 17 were included. Overall, evidence on the use of diabetes technologies in people with T1DM and disordered eating is scarce. The majority of the studies reports findings on CSII in people with T1DM and dysfunctional eating behaviours or eating disorders. Findings predominantly stem from observational data and are, in most cases, secondary findings of the respective studies. Providing the greatest flexibility in diabetes management, CSII may have benefits in disordered eating. CGM data may complement the diagnostic process of disordered eating with a physiological indicator of insulin restriction (i.e. time spent in hyperglycaemia).

CONCLUSIONS

Results on possible (dis)advantages of diabetes technology use in people with T1DM and disordered eating are based on observational data, small pilot trials and anecdotical evidence from case reports. Prospective data from larger samples are needed to reliably determine potential effects of diabetes technology on disordered eating in T1DM.

Identifying and managing eating disorders in type 1 diabetes mellitus: An all-Wales study

BACKGROUND

Co-morbid diabetes and eating disorders have a particularly high mortality, significant in numbers and highly dangerous in terms of impact on health and wellbeing. However, not much is known about the level of awareness, knowledge and confidence amongst healthcare professionals regarding co-morbid Type 1 Diabetes Mellitus (T1DM) and eating disorders.

AIM

To understand the level of knowledge and confidence amongst healthcare professionals in Wales regarding co-morbid T1DM and eating disorder presentations, identification and treatment.

RESULTS

We conducted a survey of 102 Welsh clinicians in primary care, diabetes services and eating disorder services. 60.8% expressed low confidence in identification of co-morbid T1DM and eating disorders. Respondents reported fewer cases seen than would be expected. There was poor understanding of co-morbid T1DM and eating disorders: 44.6% identified weight loss as a main symptom, 78.4% used no screening instruments, and 80.3% consulted no relevant guidance. The respondents expressed an awareness of their lack of knowledge and the majority expressed willingness to accept training and education.

CONCLUSION

We suggest that priority must be given to education and training of all healthcare professionals in primary care, diabetes services and mental health services who may see patients with co-morbid T1DM and eating disorders.

Coeliac disease is associated with depression in children and young adults with type 1 diabetes: results from a multicentre diabetes registry

AIMS

To analyse the association between coeliac disease (CD) and depression in children, adolescents, and young adults with type 1 diabetes (T1D).

METHODS

We included 79,067 T1D patients aged 6-20 years, with at least six months of diabetes duration, and treatment data between 1995 and 2019 were documented in the diabetes patient follow-up registry. We categorized patients into four groups: T1D only (n = 73,699), T1 + CD (n = 3379), T1D + depression (n = 1877), or T1D + CD + depression (n = 112).

RESULTS

CD and depression were significantly associated (adjusted OR: 1.25 [1.03-1.53]). Females were more frequent in both the depression and the CD group compared with the T1D only group. Insulin pumps were used more frequently in T1D + CD and T1D + depression compared with T1D only (both p < .001). HbA1c was higher in T1D + depression (9.0% [8.9-9.0]), T1D + CD + depression (8.9% [8.6-9.2]), both compared with T1D only (8.2% [8.2-8.2], all p < .001). We found comorbid autism, attention deficit hyperactivity disorder, anxiety, schizophrenia, and eating disorders more frequently in the T1D + CD + depression group compared with T1D only (all p < .001).

CONCLUSIONS

CD and depression are associated in young T1D patients. The double load of T1D and CD may lead to an increased risk for depression. Depression was associated with additional psychological and neurological comorbidities. Aside from imperative CD screening after T1D diagnosis and regular intervals, depression screening might be helpful in routine care, especially in patients with diagnosed CD.

Worse glycemic control, higher rates of diabetic ketoacidosis, and more hospitalizations in children, adolescents, and young adults with type 1 diabetes and anxiety disorders

The aim of the study was to explore the metabolic characteristics and outcome parameters in youth with type 1 diabetes and anxiety disorders. HbA1c levels, rates of severe hypoglycemia, diabetic ketoacidosis (DKA), and hospital admission in children, adolescents, and young adults with type 1 diabetes and an anxiety disorder from 431 diabetes-care-centers participating in the nationwide German/Austrian/Swiss/Luxembourgian diabetes survey DPV were analyzed and compared with youth without anxiety disorders. Children, adolescents, and young adults with type 1 diabetes and anxiety disorders (n = 1325) had significantly higher HbA1c (8.5% vs. 8.2%), higher rates of DKA (4.2 vs. 2.5 per 100 patient-years), and higher hospital admission rates (63.6 vs. 40.0 per 100 patient-years) than youth without anxiety disorders (all p < 0.001). Rates of severe hypoglycemia did not differ. Individuals with anxiety disorders other than needle phobia (n = 771) had higher rates of DKA compared to those without anxiety disorders (4.2 vs. 2.5 per 100 patient-years, p = 0.003) whereas the rate of DKA in individuals with needle phobia (n = 555) was not significantly different compared to those without anxiety disorders. Children, adolescents, and young adults with anxiety disorders other than needle phobia had higher hospitalization rates (73.7 vs. 51.4 per 100 patient-years) and more inpatient days (13.2 vs. 10.1 days) compared to those with needle phobia (all p < 0.001). Children, adolescents, and young adults with type 1 diabetes and anxiety disorders had worse glycemic control, higher rates of DKA, and more hospitalizations compared to those without anxiety disorders. Because of the considerable consequences, clinicians should screen for comorbid anxiety disorders in youth with type 1 diabetes.

An open trial of app-assisted acceptance and commitment therapy (iACT) for eating disorders in type 1 diabetes

BACKGROUND

Eating disorders (EDs) among individuals with type 1 diabetes (T1D) increase the risk of early and severe diabetes-related medical complications and premature death. Conventional eating disorder (ED) treatments have been largely ineffective for T1D patients, indicating the need to tailor treatments to this patient population and the unique conditions under which ED symptoms emerge (in the context of a chronic illness with unrelenting demands to control blood glucose, diet and exercise). The current study was a pilot open trial of iACT, a novel intervention for EDs in T1D grounded in Acceptance and Commitment Therapy (ACT). iACT was based on the premise that ED symptoms emerge as individuals attempt to cope with T1D and related emotional distress. iACT taught acceptance and mindfulness as an alternative to maladaptive avoidance and control, and leveraged personal values to increase willingness to engage in T1D management, even when it was upsetting (e.g., after overeating). A tailored mobile application ("app") was used in between sessions to facilitate the application of ACT skills in the moment that individuals are making decisions about their diabetes management.

METHODS

Adults with T1D who met criteria for an ED completed 12 sessions of iACT (with three optional tapering sessions). In addition to examining whether treatment was acceptable and feasible (the primary aim of the study), the study also examined whether iACT was associated with increased psychological flexibility (i.e., the ability to have distressing thoughts/feelings about diabetes while pursuing personally meaningful values), and improvements in ED symptoms, diabetes management and diabetes distress.

RESULTS

Treatment was acceptable to T1D patients with EDs and feasible to implement. Participants reported increased psychological flexibility with diabetes-related thoughts/feelings, and less obstruction and greater progress in pursuing personal values. There were large effects for change in ED symptoms, diabetes self-management and diabetes distress from baseline to end-of-treatment (Cohen's d = .90-1.79). Hemoglobin A1c also improved, but the p-value did not reach statistical significance, p = .08.

CONCLUSIONS

Findings provide preliminary evidence for iACT to improve outcomes for T1D patients with EDs and support further evaluation of this approach in a controlled trial.

Priorities in the Interdisciplinary Approach of Specific Learning Disorders (SLD) in Children with Type I Diabetes Mellitus (T1DM). From Theory to Practice

BACKGROUND

A considerable endeavor had taken place in order to understand the associated challenges for children and adolescents with Specific Learning Disorder (SLD) and Type 1 Diabetes Mellitus (T1DM) but also in order to describe the necessary skills and approaches that the care givers have to develop to assist both children and parents. (1) Aim: The aim of this review is twofold. Firstly, to highlight the T1DM's potential impact on psychological well-being, on cognitive functioning and on school performance in children and adolescents who confront SLD. Secondly, to discuss the necessity of a multidiscipline approach of poor school performance in students with SLD and T1DM, presenting the serious contribution of care providers: (a) parents/carers in the family setting, (b) teachers and psychologists in the school setting and (c) health specialists (pediatricians, nutricians, nurses, child psychiatrists and psychologists) in the medical setting. (2) Methods: In this narrative literature review of 12 selected articles, each one studies a special aspect of approach, during the diagnosis and the treatment of individuals with T1DM and SLD. The review concerns the arising problems and difficulties in the adherence to diagnosis, the management of insulin, the mental and physical wellbeing, the school performance, the cognitive functioning and learning difficulties of patients. We tried to synthesize an interdisciplinary approach that involves collaboration between family, school and medical frame; facilitating children's and adolescents' difficulties management, as well as parent and teacher involvement during the intervention implementation. (3) Results: The main issues of concern were examined through the available literature, as different factors had to be re-examined in the previous studies, regarding the potential impact of T1DM in cognitive and psychological functioning, as well as the effects of the intervention/approach/treatment of children and adolescents with SLD and T1DM. (4) Conclusions: Although T1DM diagnosis and demanding treatment are a heavy burden for children and their families, T1DM may or may not be associated with a variety of academic and psychological outcomes. Despite the variability of the reviewed research design quality, it was clearly defined that the impact of T1DM is not uniform across educational and mental variables. Strengthening the children's physical, psychological and social wellbeing is an especially important factor, as it facilitates the insulin's management as well as the learning difficulties. This is possible by supporting the parental and teacher involvement in the intervention process. This review highlights the need to reduce the distance between theory/research and practice, in some of the proposed areas in this field of knowledge.

Disordered eating behaviors in youths with type 1 diabetes during COVID-19 lockdown: an exploratory study

BACKGROUND

Recent research indicates that patients with type 1 diabetes (T1D) are at higher risk for disordered eating behaviors (DEBs) than their peers without diabetes. The present study aimed to explore the prevalence of DEBs in a sample of Italian children and adolescents with T1D and in matched-pair healthy controls during the COVID-19 lockdown.

METHODS

In a cross-sectional study, 138 children and adolescents with T1D (aged 8.01-19.11 years, 65 boys) attending a Southern Italian diabetic service and 276 age- and gender-matched healthy peers voluntarily completed an online survey about eating behaviors (ChEAT and EAT-26), anthropometric characteristics, and clinical characteristics.

RESULTS

8.69% (N = 12) of participants with T1D and 13.4% (N = 37) of controls had ChEAT/EAT-26 scores indicating presence of DEBs, with no differences between patients-whether children (total ChEAT score F(1, 157) = .104, p = .748) or adolescents (total EAT-26 score F(1, 255) = .135, p = .731)-and healthy peers. zBMI values were lower than those measured in the latest diabetes visit (p < .0001), while HbA1c values remained unchanged (p = .110). In both groups, adolescents had lower Oral Control scores than children (T1D: F(1, 138) = 20.411, p < .0001, η2 = .132, controls: F(1, 276) = 18.271, p < .0001, η2 = .063); additionally, gender (female) and age were found to be significant predictors of several ChEAT/EAT-26 scores.

CONCLUSIONS

This exploratory study suggested that children and adolescents with T1D did not experience more DEB symptoms during the COVID-19 lockdown compared to healthy controls. Results revealed DEBs as more of a female adolescent developmental issue rather than a result of the challenges of living with a chronic illness under quarantine measures. Possible effects of parental pressure on their children's eating behaviors in the context of home confinement and of using a non-diabetes-specific measure to assess DEBs are discussed.

Psychische Komorbiditäten bei Jugendlichen und jungen Erwachsenen mit Typ-1-Diabetes

Jugendliche und junge Erwachsene mit Typ-1-Diabetes sind häufig von komorbiden psychischen Störungen betroffen. Dabei zeigt die Studienlage zur Verbreitung ein heterogenes und inkonsistentes Bild. Diagnose und Behandlung der somatopsychischen Begleiterkrankungen beeinflussen den Behandlungs- und Krankheitsverlauf sowie die Lebensqualität der Betroffenen. Trotzdem wird dies in der klinischen Praxis selten frühzeitig berücksichtigt. Das multizentrische Verbundprojekt COACH verfolgt das Ziel, die Erkennung und Behandlung psychischer Komorbidität für diese Zielgruppe in der bundesweiten Routineversorgung zu optimieren.

Psychological care in children and adolescents with type 1 diabetes in a real-world setting and associations with metabolic control

BACKGROUND

International guidelines recommend psychosocial care for children and adolescents with type 1 diabetes.

OBJECTIVE

To assess psychological care in children and adolescents with type 1 diabetes in a real-world setting and to evaluate associations with metabolic outcome.

METHODS

Delivery of psychological care, HbA1c, and rates of severe hypoglycemia and diabetic ketoacidosis (DKA) in children and adolescents with type 1 diabetes from 199 diabetes care centers participating in the German diabetes survey (DPV) were analyzed.

RESULTS

Overall, 12 326 out of 31 861 children with type 1 diabetes were supported by short-term or continued psychological care (CPC). Children with psychological care had higher HbA1c (8.0% vs 7.7%, P<.001) and higher rates of DKA (0.032 vs 0.021 per patient-year, P<.001) compared with children without psychological care. In age-, sex-, diabetes duration-, and migratory background-matched children, HbA1c stayed stable in children supported by CPC during follow-up (HbA1c 8.5% one year before psychological care started vs 8.4% after two years, P = 1.0), whereas HbA1c was lower but increased significantly by 0.3% in children without psychological care (HbA1c 7.5% vs 7.8% after two years, P <.001). Additional HbA1c-matching showed that the change in HbA1c during follow-up was not different between the groups, but the percentage of children with severe hypoglycemia decreased from 16.3% to 10.7% in children receiving CPC compared with children without psychological care (5.5% to 5.8%, P =.009).

CONCLUSIONS

In this real-world setting, psychological care was provided to children with higher HbA1c levels. CPC was associated with stable glycemic control and less frequent severe hypoglycemia during follow-up.

Clinical features of the diabetes eating problem survey-revised Turkish version in children and adolescent with type 1 diabetes

Objectives We aim to delineate clinical characteristics that place individuals with type 1 diabetes (T1DM) at risk of developing eating problems by using Turkish version of diabetes eating problem survey-revised (DEPS-R). Methods The patients aged 9-18 years with T1DM who came to the pediatric endocrine outpatient clinic for control between February and December 2019 completed Turkish version of DEPS-R. Clinical and laboratory findings were obtained from patient files. Cases with a questionnaire score ≥20 were considered to be at risk for eating disorders (ED). Parents were informed when the results of the screening were positive, and were offered to child psychiatrist. Results The median scores obtained with the Turkish version of DEPS-R for the total sample, for females and males were 15, 16, and 13 respectively. The score was significantly higher among females compared to males (p<0.001). DEPS-R score positive group had higher age (mean [SD]=14.6 [2.7], p=0.009), BMI (mean [SD]=21.4 [3.2], p<0.001), HbA1c % (mean [SD]=9.37[2.3], p<0.001) and year of diabetes duration (mean [SD]=5.5 [3.6], p<0.001) compared to the negative group. Conclusions Early recognition and adequate treatment of ED in T1DM is essential. DEPS-R is sensitive in identifying young people with ED.

Eating Disorders and Diabetes

PURPOSE OF REVIEW

This review describes the characteristics of patients with eating disorders in both type 1 and type 2 diabetes and the principles of their treatment.

RECENT FINDINGS

The combination of type 1 diabetes and an eating disorder is sometimes known as "diabulimia". The hallmark of the condition is that the patient deliberately takes an inadequate amount of insulin in order control their body weight (insulin restriction). Other disordered eating behaviours, such as dietary restriction, self-induced vomiting and binge eating, may also be present but typical anorexia nervosa is rare. There is an increased prevalence of eating disorders in adolescents with type 1 diabetes, which is estimated at 7%. The combination of type 1 diabetes and an eating disorder leads to elevated levels of HbA1c and an increased risk of both acute and chronic complications. Screening is recommended but rarely carried out. Management requires an understanding of the inter-relationships between eating behaviour, mood, blood glucose and insulin administration. Treatment aims to introduce a regular eating pattern and support the patient to increase their insulin dose gradually. Eating disorders also occur in those with type 2 diabetes, where binge eating disorder is the most common diagnosis. Eating disorders are common in both type 1 and type 2 diabetes, with an increased prevalence of complications in type 1. Treatment requires an understanding of both diabetes and eating behaviour.

Gestörtes Essverhalten und psychosoziale Versorgungssituation junger Menschen mit Typ 1 Diabetes

Einleitung Gestörtes Essverhalten oder klinisch relevante Essstörungen in Verbindung mit Typ 1 Diabetes haben schwerwiegende Folgen für die Qualität der Stoffwechseleinstellung und die langfristige gesundheitliche Prognose Betroffener. Eine frühzeitige Diagnose und qualifizierte therapeutische Interventionen können bereits bei gestörtem Essverhalten dazu beitragen, vorzeitige mikrovaskuläre Schädigungen zu vermeiden. In dieser Studie wurden für eine Gruppe junger Menschen mit Typ 1 Diabetes, die an einem 4-tägigen Camp teilnahmen, die Prävalenz essgestörten Verhaltens und die spezifische psychosoziale Versorgungssituation untersucht.

Material und Methoden Während eines bundesweit ausgeschriebenen Diabetescamps für junge Menschen (16–29 Jahre) beantworteten die Teilnehmenden Fragen zu ihrer aktuellen Diabetesbehandlung, zu diabetesspezifischen Belastungen (PAID-5) sowie zur psychosozialen Versorgung im Rahmen der ambulanten Langzeittherapie. Symptome gestörten Essverhaltens wurden mit einem diabetesspezifischen Screeningfragebogen, dem Diabetes Eating Problem Survey-Revised (DEPS-R), erhoben. Eine lineare multiple Regression wurde berechnet, um Prädiktoren gestörten Essverhaltens zu identifizieren.

Ergebnisse An der Umfrage beteiligten sich 308 junge Menschen mit Typ 1 Diabetes (Alter 21,4±3,4 Jahre; 73% weiblich; Diabetesdauer 10,2±5,9 Jahre; 74% in internistischer Behandlung). Bei 28,2% der Befragten ergaben sich Hinweise auf ein gestörtes Essverhalten (17% der Männer, 32% der Frauen). Teilnehmende mit einem auffälligen Summenwert im DEPS-R wurden nur zu 7% entsprechend psychologisch betreut. Das HbA1c, der BMI, die diabetesspezifischen Belastungen, das Alter, die Diabetesdauer sowie das Geschlecht erwiesen sich als signifikante Prädiktoren für das Ausmaß gestörten Essverhaltens.

Diskussion Unter den Teilnehmenden eines Diabetescamps für junge Menschen zeigten sich bei über einem Viertel Hinweise auf ein gestörtes Essverhalten. Insgesamt waren davon junge Frauen häufiger betroffen, weitere relevante Risikofaktoren waren ein erhöhter BMI, ein höheres HbA1c und stärkere diabetesspezifische Belastungen. Nur ein sehr geringer Anteil der jungen Menschen mit Typ 1 Diabetes und gestörtem Essverhalten erhielt psychologische Unterstützung.

Schlussfolgerung In der ambulanten diabetologischen Versorgung sollten diabetesspezifische Screeninginstrumente und/oder gezielte Screeningfragen insbesondere bei jungen Frauen regelmäßig eingesetzt und die Ergebnisse mit den Betroffenen im Hinblick auf eine weiterführende Behandlung besprochen werden.

Eating disorder animal model

PURPOSE OF REVIEW

The aim of this review is to describe animal models that simulate the features of eating disorders. The literature pertaining to animal models that are of relevance for clinical eating disorders and the possible underpinning mechanisms was reviewed using PubMed, Ovid database and Google Scholar.

RECENT FINDINGS

New refinements of the circuits regulated by neurotransmitters and neuropeptides which instigate eating behaviours and the various feedback pathways which monitor acute and chronic nutrient status continue to be discovered. Moreover, work with the animal models that simulate the behavioural features and risk factors related to eating disorders is flourishing and providing new insights into possible causal mechanisms. For example, rodents develop binge-eating behaviours if they are intermittently exposed to processed, palatable foods and/or sugar adulterated drinks. This led to the controversial conceptualization of binge eating as a form of food addiction. Self-starvation taken to a fatal consequence such as occurs in anorexia nervosa can emerge in rodents exposed to triggers like social exclusion and/or the opportunity to exercise.

SUMMARY

There are plausible animal models for both anorexia nervosa and binge-eating disorders. These can be used to elaborate the theoretical models to explain the mechanisms underpinning eating disorders.

Course of Disordered Eating Behavior in Young People With Early-Onset Type I Diabetes: Prevalence, Symptoms, and Transition Probabilities

PURPOSE

The aims of this study were to analyze the prevalence and course of disordered eating behavior (DEB) in adolescents with intensively treated type I diabetes, describe differences in age-specific DEB symptoms, and identify predictors of current DEB.

METHODS

Data were taken from 332/218 11- to 27-year-old participants (55.7% girls/women, mean age [SD] 17.8 [3.4] years, mean diabetes duration 14.9 [3.0] years) of two/three surveys of a Germany-wide longitudinal study on early-onset and long duration diabetes, respectively. A diabetes-adapted version of the SCOFF questionnaire was used to assess DEB. Both screening-based overall and age- and sex-specific prevalence of DEB and its symptoms were determined. To estimate transition probabilities between DEB states, first-order Markov transition models were implemented adjusting for previous sociodemographic, socioeconomic, and diabetes-specific covariates.

RESULTS

The overall screening-based DEB prevalence among all 1,318 observations was 10.8% (95% confidence interval [CI]: 9.2%, 12.6%) with age-specific differences in symptom prevalence. Transition probabilities for developing/persistent DEB were twofold higher among female than male participants (risk ratio [RR] 2.3 [1.4, 3.9]/2.1 [1.3, 3.4]). In multiple adjusted regression, previous DEB (odds ratio [OR] 2.8 [95% CI 1.4, 5.6]), follow-up time (OR_{per 1-year increase} 3.4 [1.4, 8.0]), and sex (OR_girls/women 2.1 [1.1, 3.9]) were the most important predictors of current DEB with further weaker associations for previous age and HbA_1c.

CONCLUSIONS

Our results contribute to better understanding the course of DEB in patients with early-onset diabetes and emphasize the relevance of regular DEB screenings including the age group of young adults.

Examination of Psychosocial and Physiological Risk for Bulimic Symptoms in Youth With Type 1 Diabetes Transitioning to an Insulin Pump: A Pilot Study

Objectives

This study tested hypotheses drawn from a risk model positing that psychosocial risk plus disease-related and treatment factors contribute to bulimic symptoms in youth with type 1 diabetes (T1D) transitioning to an insulin pump. The goal of this study was to examine whether disease-related factors, particularly disease- and treatment-based disruption in hunger and satiety, contribute to report of bulimic symptoms in youth with T1D after accounting for psychosocial risk factors.

Methods

43 youth (ages 10-17, 54% female) with established T1D were recruited before transition from multiple daily injections to insulin-pump therapy from three tertiary pediatric diabetes centers. Participants completed measures of bulimic symptoms, depressive symptoms dietary restraint, and the Diabetes Treatment and Satiety Scale, a diabetes-specific questionnaire assessing hunger and satiety cues and eating behavior in response to blood glucose levels and treatment.

Results

Hierarchical multiple regression was used to assess contributions of psychosocial and disease-based risk to report of bulimic symptoms. After assessing the contributions of body mass index, body image dissatisfaction, and dietary restraint, a significant 2-way interaction emerged between depression and diabetes-related uncontrollable hunger related to bulimic symptoms (β = 1.82, p < .01).

Conclusions

In addition to psychosocial risk, disease- and treatment-based hunger and satiety dysregulation appear to be important factors contributing to report of bulimic symptoms in youth with T1D. These preliminary findings have significant treatment implications for bulimic symptoms in youth with T1D.

Factors associated with disordered eating behaviours in adolescents with Type 1 diabetes

AIMS

To assess the occurrence of disordered eating behaviours in teenagers with Type 1 diabetes and to compare characteristics according to level of disordered eating behaviours.

METHODS

In this cross-sectional study, we collected adolescents' demographic and diabetes management data by parent-youth interview and chart review. Teenagers completed psychosocial surveys, including the Diabetes Eating Problem Survey-Revised (DEPS-R), a diabetes-specific measure of disordered eating behaviours. We categorized teenagers according to level of disordered eating behaviours: low, DEPS-R score <10; moderate, DEPS-R score 10-19; and high, DEPS-R score ≥20.

RESULTS

The 178 teenagers (48% girls) were aged 14.9±1.3 years, with diabetes duration of 7.4±3.7 years. Most (59%) had low, 26% had moderate, and 15% had high levels of disordered eating behaviours. Several biomedical and psychosocial characteristics differed by level of disordered eating behaviours. There were more girls in the moderate (62%) and high (65%) than in the low level of disordered eating behaviours group (37%; P=0.003) and more obese teenagers in the moderate (13%) and high (27%) groups than in the low group (4%; P=0.0003). Frequency of daily blood glucose monitoring decreased (P=0.0006) and HbA_1c level increased (P=0.01) with greater level of disordered eating behaviours. A greater level of disordered eating behaviours was also associated with poorer treatment adherence, more negative affect regarding blood glucose monitoring, poorer quality of life, and more depressive symptoms (all P<0.0001), along with more diabetes-specific family conflict (P=0.01).

CONCLUSIONS

Identifying teenagers with Type 1 diabetes who have moderate and high levels of disordered eating behaviours may prevent progression to eating disorders and substantial morbidity by directing support and intervention efforts to those in need.

Worse Metabolic Control and Dynamics of Weight Status in Adolescent Girls Point to Eating Disorders in the First Years after Manifestation of Type 1 Diabetes Mellitus: Findings from the Diabetes Patienten Verlaufsdokumentation Registry

OBJECTIVE

To assess indications of eating disorders in girls with type 1 diabetes mellitus (T1DM).

STUDY DESIGN

In total 31 556 girls aged >6 months and <23 years of age with T1DM from the Diabetes Patienten Verlaufsdokumentation (DPV) cohort were analyzed including 155 (0.49%) girls with anorexia nervosa, 85 (0.27%) girls with bulimia nervosa, 45 (0.14%) girls with binge eating disorder, and 229 (0.73%) girls with eating disorders not otherwise specified. Patient characteristics, weight changes, numbers of patients with severe hypoglycemia and diabetic ketoacidosis (DKA), changes of glycosylated hemoglobin A1c (HbA1c) levels, use of pumps, and prevalence of celiac disease and autoimmune thyroiditis were compared between girls with and without eating disorders. Multiple logistic regression analyses were performed.

RESULTS

Eating disorders were significantly associated with late pubertal age, nonusage of pumps, no migration background, increased HbA1c levels, increased frequencies of DKA and severe hypoglycemia, and celiac disease were not related to eating disorders. Significant differences in HbA1c levels, prevalence of DKA and severe hypoglycemia between girls with and without eating disorders were already detectable in the first years after onset of T1DM. A decrease of body mass index (BMI)-SDS increased the risk for comorbid anorexia nervosa (7.1-fold [95% CI 3.6-14.3] compared with stable BMI-SDS, 6.9-fold [95%CI 3.4-14.1] compared with increase of BMI-SDS).

CONCLUSIONS

Poor metabolic control and increased rates of DKA and severe hypoglycemia in the first years after manifestation of T1DM can be hints for eating disorders in girls with T1DM, and weight loss is specific for anorexia nervosa. These clinical features should lead to screening for eating disorders especially at a late pubertal age.

Association of insulin-manipulation and psychiatric disorders: A systematic epidemiological evaluation of adolescents with type 1 diabetes in Austria

BACKGROUND/OBJECTIVE

The aim of this study was to systematically assess the association of insulin-manipulation (intentional under- and/or overdosing of insulin), psychiatric comorbidity and diabetes complications.

METHODS

Two diagnostic interviews (Diabetes-Self-Management-Patient-Interview and Children's-Diagnostic-Interview for Psychiatric Disorders) were conducted with 241 patients (age 10-22) with type 1 diabetes (T1D) from 21 randomly selected Austrian diabetes care centers. Medical data was derived from medical records.

RESULTS

Psychiatric comorbidity was found in nearly half of the patients with insulin-manipulation (46.3%) compared to a rate of 17.5% in patients, adherent to the prescribed insulin therapy. Depression (18.3% vs 4.9%), specific phobia (21.1% vs 2.9%), social phobia (7.0% vs 0%), and eating disorders (12.7% vs 1.9%) were elevated in patients with insulin-manipulation. Females (37.7%) were more often diagnosed (P = 0.001) with psychiatric disorders than males (18.4%). In females, the percentage of psychiatric comorbidity significantly increased with the level of non-adherence to insulin therapy. Insulin-manipulation had an effect of +0.89% in HbA1c (P = <0.001) compared to patients adherent to insulin therapy, while there was no association of psychiatric comorbidity with metabolic control (HbA1c 8.16% vs 8.12% [65.68 vs 65.25 mmol/mol]). Ketoacidosis, severe hypoglycemia, and frequency of outpatient visits in a diabetes center were highest in patients with insulin-manipulation.

CONCLUSIONS

This is the first study using a systematic approach to assess the prevalence of psychiatric disorders in patients who do or do not manipulate insulin in terms of intentional under- and/or overdosing. Internalizing psychiatric disorders were associated with insulin-manipulation, especially in female patients and insulin-manipulation was associated with deteriorated metabolic control and diabetes complications.

Poor Metabolic Control in Children and Adolescents With Type 1 Diabetes and Psychiatric Comorbidity

OBJECTIVE

Type 1 diabetes is associated with an increased risk of psychiatric morbidities. We investigated predictors and diabetes outcomes in a pediatric population with and without psychiatric comorbidities.

RESEARCH DESIGN AND METHODS

Data from the Danish Registry of Childhood and Adolescent Diabetes (DanDiabKids) and National Patient Register were collected (1996-2015) for this population-based study. We used Kaplan-Meier plots to investigate whether age at type 1 diabetes onset and average glycated hemoglobin (HbA_1c) levels during the first 2 years after onset of type 1 diabetes (excluding HbA_1c at debut) were associated with the risk of being diagnosed with a psychiatric disorder. Mixed-effects linear and logistic regression models were used to analyze HbA_1c, BMI, severe hypoglycemia (SH), or ketoacidosis as outcomes, with psychiatric comorbidities as explanatory factor.

RESULTS

Among 4,725 children and adolescents with type 1 diabetes identified in both registers, 1,035 were diagnosed with at least one psychiatric disorder. High average HbA_1c levels during the first 2 years predicted higher risk of psychiatric diagnoses. Patients with psychiatric comorbidity had higher HbA_1c levels (0.22% [95% CI 0.15; 0.29]; 2.40 mmol/mol [1.62; 3.18]; P < 0.001) and an increased risk of hospitalization with diabetic ketoacidosis (1.80 [1.18; 2.76]; P = 0.006). We found no associations with BMI or SH.

CONCLUSIONS

High average HbA_1c levels during the first 2 years after onset of type 1 diabetes might indicate later psychiatric comorbidities. Psychiatric comorbidity in children and adolescents with type 1 diabetes increases the risk of poor metabolic outcomes. Early focus on the disease burden might improve outcomes.

'Diabulima' through the lens of social media: a qualitative review and analysis of online blogs by people with Type 1 diabetes mellitus and eating disorders

AIMS

To perform a qualitative review of online blogs authored by people self-identifying as having Type 1 diabetes and an eating disorder or 'diabulimia', a term used by people with Type 1 diabetes to describe an eating disorder that is characterized by deliberate restriction of insulin to control weight.

METHODS

We conducted a structured qualitative review of online blogs published between 2012 and 2017 authored by people who report having Type 1 diabetes and an eating disorder or diabulimia. The subsequent thematic analysis followed a six-phase process and was conducted by two independent researchers.

RESULTS

From 147 000 search results, 11 blogs (304 posts) matched criteria for further analyses. Three key themes and 18 subthemes emerged: 1) different aspects of bloggers' relationship with insulin, including motives for omitting insulin, secrecy of insulin omission and perception of control; 2) bloggers' experiences of diabetes complications, and diabetes ketoacidosis in particular, as well as their worries about future complications; 3) strategies for recovery and triggers for relapse, which involved diabetes self-management and setting up a support system.

CONCLUSIONS

Qualitative analyses of blogs authored by people with Type 1 diabetes and an eating disorder or diabulimia have identified high levels of diabetes distress and provided insight into different motives for insulin omission and strategies for recovery. Considering the limited evidence for effective interventions, these findings may help the development of complex interventions to improve biomedical and psychological outcomes in this group.

Trajectories of Body Mass Index from Childhood to Young Adulthood among Patients with Type 1 Diabetes-A Longitudinal Group-Based Modeling Approach Based on the DPV Registry

OBJECTIVE

To identify distinct longitudinal patterns of body mass index (BMI) z score in type 1 diabetes from childhood to young adulthood and secondly to determine sex differences as well as associated clinical covariates.

STUDY DESIGN

A total of 5665 patients with type 1 diabetes (51% male) with follow-up from 8 to 20 years of age from the multicenter diabetes prospective registry DPV were studied (baseline diabetes duration ≥1 years, BMI z score aggregated per year of life). Latent class growth modeling (SAS: PROC TRAJ) was applied to analyze BMI z score over time.

RESULTS

Six distinct BMI z score trajectories were identified (group 1: 7% of patients, group 2: 22%, group 3: 20%, group 4: 16%, group 5: 25%, and group 6: 10%). Group 1, 2, 5, and 6 had an almost stable BMI z score, either in the low, near-normal, high stable, or chronic overweight range. Group 3 (60% girls) increased their BMI during puberty, whereas group 4 (65% boys) had a BMI decrease. Similar patterns were observed for girls only, whereas boys followed nearly stable trajectories without fluctuation over time. Between the near-normal and the other groups, significant differences (P < .05) in sex ratio, migration background, mental health, height z score, glycated hemoglobin A1c, diabetes treatment, dyslipidemia, hypertension, and smoking were observed.

CONCLUSIONS

In youth with type 1 diabetes, a great heterogeneity of BMI z score trajectories exists that highlight the importance of personalized sex-specific intervention programs for subjects at risk for unfavorable BMI development.

Disordered eating behaviors in adolescents with type 1 diabetes: A cross-sectional population-based study in Italy

OBJECTIVE

To evaluate the association of clinical, metabolic and socioeconomic factors with disordered eating behaviors (DEB) among adolescents with type 1 diabetes screened using the Diabetes Eating Problem Survey-Revised (DEPS-R).

METHODS

A cross-sectional, population-based study involved 163 adolescents with type 1 diabetes, aged 11-20 years, recruited from the registry for type 1 diabetes of Marche Region, Italy, who completed the DEPS-R (response rate 74.4%). Clinical characteristics, lipid profile, HbA_1c , family profile of education and occupation were evaluated. The Italian version of DEPS-R was validated, and the prevalence of DEB estimated. The association of demographic, socioeconomic, and clinical factors with DEB was evaluated by multiple correspondence analysis and multiple logistic regression.

RESULTS

The prevalence of DEPS-R-positive (score ≥20) was 27% (95% CI 17-38) in boys and 42% (95% CI 31-53) in girls. A clinical profile of DEPS-R-positive was identified: overweight, little time spent in physical activity, low socioeconomic status, poor metabolic control, skipping insulin injections. Furthermore, the probability of DEPS-R-positive increased 63% for every added unit of HbA_1c , 36% for every added number of insulin injections skipped in a week and decreased about 20% for every added hour/week spent in physical activity. Overweight youth were six times more likely to be DEPS-R-positive.

DISCUSSION

A specific clinical profile of DEPS-R-positive was identified. A multidisciplinary clinical approach aimed to normalize eating behaviors and enhance self-esteem should be used to prevent the onset of these behaviors, and continuous educational programs are needed to promote healthy behaviors and lifestyles.

Royal College of Psychiatrists Liaison Faculty & Joint British Diabetes Societies (JBDS): guidelines for the management of diabetes in adults and children with psychiatric disorders in inpatient settings

The Royal College of Psychiatrists Liaison Faculty & Joint British Diabetes Societies (JBDS) for Inpatient Care guidelines for the management of diabetes in adults and children with psychiatric disorders in inpatient settings are available in full at: www.diabetes.org.uk/joint-british-diabetes-society and https://abcd.care/joint-british-diabetes-societies-jbds-inpatient-care-group. This article summarizes the guidelines and recommendations. Commissioners are urged to ensure that the needs of people with diabetes and severe mental illness are specifically addressed in contracts with providers of inpatient care, and to avoid financial or other barriers to cross-organizational working and to ensure that patient-structured education is commissioned to meets the complex needs of people with diabetes and severe mental illness. Acute trusts are asked to develop joint pathways with mental health providers and facilitate multidisciplinary working and to screen for mental ill health in those admitted with acute complications of diabetes whose aetiology is unclear or not medically explained. Mental health trusts should create a diabetes register, screen for diabetes, particularly in those prescribed second-generation antipsychotics and ensure that staff are trained in managing and avoiding hypoglycaemia, and the safe use of insulin. Finally, clinical teams should ensure that all staff can access training in diabetes and mental health to support them to care for people with both diabetes and severe mental illness, develop local pathways for joint working and ensure best practice tariff criteria are met for diabetic ketoacidosis and hypoglycaemia, and for children and young people with diabetes.
