Prevalence of disturbed eating behavior and associated symptoms of anxiety and depression among adult males and females with type 1 diabetes

Eating Disorders and Sleep Disturbance as Determinants of Metabolic Control in Adolescents with Type 1 Diabetes

This cross-sectional study examined the effect of sleep disturbance and eating disorders on metabolic control in adolescents with Type 1 Diabetes. The study was conducted with adolescents with T1DM treated at a university hospital in Turkey between October 2023 and January 2024. The study sample consisted of 120 adolescents with T1DM between the ages of 10-18. Data were collected online using the Adolescent Information Form, Dutch Eating Behavior Questionnaire (DEBQ), and DSM-5 Sleep Disorder Scale (SDS). Mean, percentage, and regression analyses were used to analyze the data. Ethics committee, institutional permission and written permission from the adolescents with Type 1 Diabetes and their parents were obtained for the study. In the current study, sleep disturbance and eating disorders explained 38.5% and 40.2% of HbA1c, respectively, and were found to have a significant effect (respectively: F = 73.737, p ≤ .001; F = 19.353, p ≤ .001). This study provides evidence that eating disorders and sleep disturbance explain approximately half of HbA1c. The results of the study revealed that sleep disturbance and eating disorders were significant predictors of metabolic control in adolescents with type 1 diabetes.

The prevalence of anxiety in adult endocrinology outpatients: A systematic review and meta-analysis

INTRODUCTION

Anxiety disorders and anxiety symptoms are common mental disorders in the medically unwell and have significant impacts on patients' quality of life and engagement with psychiatric and medical services. Several systematic reviews have examined the prevalence of anxiety in specific endocrinology settings with estimates varying significantly from study to study. No meta-analysis has examined anxiety rates across the endocrinology outpatient setting. The aim of this meta-analysis is to provide endocrinologists with a precise estimate of the prevalence of anxiety - and impacting factors - in their outpatient clinics.

METHOD

PubMed, Embase, Cochrane and PsycINFO databases and Google Scholar were searched to identify studies that assessed anxiety prevalence in endocrinology outpatients published up to 23 January 2023. This was part of a larger systematic review search of anxiety prevalence in common medical outpatient clinics. Data characteristics were extracted independently by two investigators. Studies of patients 16 years and older and representative of the clinic were included. The point prevalence of anxiety or anxiety symptoms was measured using validated self-report questionnaires or structured interviews. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Pooled estimates were analysed under the random-effects model and subgroup analyses on relevant variables were conducted under a mixed-effects model. Heterogeneity was assessed using the I2 statistic.

RESULTS

Fifty-nine studies with a total of 25,176 participants across 37 countries were included in this study. The overall pooled prevalence of anxiety or anxiety symptoms was 25·1% (95%CI 21·4-29·2; 6372/25,176; n = 59). Subgroup analyses revealed no difference in prevalence between outpatients with diabetes mellitus compared to other grouped endocrine disorders. Generalized Anxiety Disorder (GAD) was the most frequent clinical diagnosis 11·7% (95%CI 8·1-16·7; I2=87·93%; 443/4604; n = 17), while panic disorder was significantly higher in the non-diabetes group 9·5% (95%CI 5·9-14·9; I2=57·28%; 56/588; n = 8), compared to the diabetes group 5·2% (95%CI 3·7-7·3; I2=32·18%; 184/3669; n = 6). Estimates of prevalence were higher when assessed with a self-report scale 32·4% (95%CI 25·6-40·0; I2=96·06%; 1565/4675; n = 21) compared to diagnostic interview 17·6% (95%CI 12·2-24·7; I2=94·39%; 636/5168; n = 21). Outpatients in developing countries had higher rates of anxiety than those in developed countries. Female diabetes patients reported higher rates of anxiety compared to males.

CONCLUSION

Our study provides evidence that anxiety occurs frequently amongst endocrinology outpatients and at a higher rate than is estimated in the general population. Given the impact anxiety has on patient outcomes, it is important that effective management strategies be developed to support endocrinologists in identifying and treating these conditions in their outpatient clinics.

Recovery Phase Nutrition and Insulin Strategies for a Collegiate Distance Runner with Type 1 Diabetes Mellitus: A Case Study

PURPOSE

There is scant published research regarding nutrition and insulin strategies for athletic performance in collegiate distance runners with type 1 diabetes mellitus (CDRT1). Acute carbohydrate supplementation (CHOsup) and insulin reduction used to minimize hypoglycemia during exercise may result in deteriorated glycemic control post exercise in CDRT1. The present case study of a CDRT1 investigated outcomes associated with a moderate-carbohydrate (ModCHO) diet and 24 h insulin adjustment during recovery phases for improved glycemic control and reduced use of acute strategies.

METHODS

During an 8-day period, a female CDRT1 followed a ModCHO (~4 g/kg/day) nutrition program. Recovery phase adjustments to insulin doses were made using an equation developed to estimate reduced insulin needs post exercise, as a function of exercise intensity and duration. Daily training was performed in the fasted state at 6:00 a.m. and included additional exercise strategies to reduce glycemic variability when needed. Daily blood glucose time-in-range (TIR) and use of CHOsup were assessed. Athlete well-being was determined using the Student-Athlete Well-Being Scale (SAWS)TM at baseline, and days 1, 3, and 7.

RESULTS

Throughout the 8-day period, mean TIR increased (77% versus < 50%) and the magnitude of glycemic excursions decreased (~3.8-15 versus ~3.0-26 mmol/L) relative to a prior comparison period. Minimal pre-exercise CHOsup was employed and CHOsup during exercise was not required. Additionally, the athlete achieved a new lifetime best in the 5000 m run and maintained positive well-being.

CONCLUSION

The present case study provides examples of recovery phase strategies (i.e., ModCHO diet and 24 h insulin adjustments) that may support glycemic control and athletic performance in CDRT1 and provides potential considerations for nutrition and insulin strategies for use by athletes and coaches.

Disordered eating behaviours and body shape dissatisfaction among adolescents with type 1 diabetes: a cross sectional study

BACKGROUND

Disordered eating behaviours (DEBs) are variations in regular eating patterns and behaviours and might include symptoms and behaviours of eating disorder with lower level of severity. Such behaviours are common during adolescence at which time several physical and psychological changes occur favouring unhealthy dietary behaviours. Although the magnitude of DEBs is high among high-income countries, similar data are limited among adolescents with diabetes in low-income countries including Ethiopia. This study aimed to assess the magnitude of DEBs and its relationship with body shape dissatisfaction among adolescents with diabetes on follow-up at selected public hospitals in Addis Ababa, Ethiopia.

METHODS

Hospital based cross sectional study was conducted among randomly selected 395 adolescents with diabetes attending public hospitals in Addis Ababa from January to December, 2021. Data were collected using structured pretested standard diabetes eating problem survey revised (DEPS-R) questionnaire, body part satisfaction scale of 8 items, and anthropometric measurements. Descriptive statistics such as median alongside interquartile range was used to describe the continuous variables. Binary bivariable and multivariable logistic regression was used for data analysis. Mann-Whitney U-test and Kruskal-Wallis test were used to evaluate the difference between median scores of independent variables. Adjusted odds ratios (AOR) alongside 95% confidence intervals (CIs) were estimated to measure the strength of association between variables of interest.

RESULTS

The magnitude of disordered eating behaviours within the last 30 days was 43.3%, [95% CI: (38%, 48%)]. In multivariable analysis, body shape dissatisfaction [AOR = 2.21, 95% CI (1.28, 3.82, p = 0.0001)], family history of diabetes mellitus [AOR = 1.59, 95% CI (1.03, 2.47, p = 0.038)], late adolescence period [AOR = 2.10, 95% CI (1.33, 3.34, p = 0.002)], having diabetic complication[AOR = 2.32, 95% CI (1.43, 3.75, p = 0.001)],and being overweight [AOR = 2.25, 95% CI (1.32, 3.82, p = 0.003)] were significantly associated with DEBs.

CONCLUSIONS

The magnitude of DEBs was high among the study participants. Body shape dissatisfaction, family history of diabetes mellitus, being in late adolescence period, diabetic complication, and nutritional status of adolescents were significantly associated with DEBs. Therefore, preventive interventions need to be designed by all relevant actors working on health promotion of young population to address factors influencing DEBs among adolescent population with diabetes.

The misuse of insulin by males with Type 1 Diabetes Mellitus for weight and/or shape control: a systematic scoping review

Background

Insulin restriction and/or omission in Type 1 Diabetes Mellitus (T1DM) is a risky disordered eating behaviour increasingly reported in the literature. Most existing literature has focused on females with T1DM. Previous research, however, suggests disordered eating behaviours are over-represented in males with T1DM versus males without T1DM. This systematic scoping review sought to summarise the existing literature to contribute to the development of an understanding of males' misuse of insulin for weight and/or shape control.

Methods

A systematic scoping review methodology was used. We searched six electronic databases. Eligible articles were quantitative, qualitative, or mixed methods empirical studies with primary data on the restriction and/or omission of insulin for weight and/or shape control among males, written in English from database inception to December 2021.

Results

A final sample of 56 articles was included (48 quantitative, six qualitative and two mixed methods). Where it was reported to occur, estimates of the behaviour ranged from 5 to 75% in females and 1.4% to 76% in males. In 12 studies examining sex differences, only three reported higher prevalence in females. Understandings about the behavioural context of the behaviour were hampered by lack of qualitative research (n = 4 studies).

Conclusion

Despite common preconceptions, this disordered eating behaviour appears to occur similarly in males and females. The findings shed light on areas for future research, including aetiology in males and the need for longitudinal and qualitative research. Clinical recommendations include being alert to the possibility of this behaviour in males with Type 1 Diabetes Mellitus and the need for health professionals to use open-ended questions to explore current and past deliberate restriction and/or omission of insulin among their patients.

Diabetes-specific eating disorder and possible associated psychopathologies in adolescents with type 1 diabetes mellitus

PURPOSE

It was aimed to investigate the frequency of the risk of diabetes-specific eating disorder (DSED) in adolescents with type 1 diabetes mellitus (T1DM) and to reveal the accompanying psychopathologies.

METHODS

Adolescents with T1DM aged 12-18 who applied to the pediatric diabetes outpatient clinic between July 2021 and March 2022 were included. Diabetes Eating Problem Survey-Revised (DEPS-R) was applied to all patients to determine the risk of DSED. In order to detect accompanying psychopathologies, Eating Disorder Examination Questionnaire (EDE-Q), Child Anxiety and Depression Scale-Child version (RCADS) and Parenting Style Scale were applied. After completing the scales, semi-structured interviews were conducted with all patients by a child and adolescent psychiatrist.

RESULTS

Ninety-two adolescents (45 boys, 47 girls) were included. DSED risk was found in 23.9% of the cases. A positive correlation was found between DEPS-R and EDE-Q scores (p = 0.001, rho = 0.370). RCADS mean scores were significantly higher in the group with DSED risk (p < 0.001). When the Parenting Style Scale was evaluated, psychological autonomy scores were significantly lower in the group with DSED risk (p = 0.029). As a result of the psychiatric interviews, 30 (32.6%) patients had at least 1 psychiatric disorder. Of these, 2 patients were diagnosed with eating disorder.

CONCLUSION

Almost one-fourth of adolescents with T1DM were found to be at risk of DSED. Routine screening of adolescents with T1DM with the DEPS-R scale may provide early detection of DSED, and referral of those at risk to child psychiatry enables early diagnosis and intervention for both eating disorders and accompanying psychopathologies.

"I am not alone". A qualitative feasibility study of eating disorders prevention groups for young females with type 1 diabetes

OBJECTIVE

The overall aim of the current study was to qualitatively explore the feasibility of eating disorder prevention groups for people with type 1 diabetes (T1D).

METHOD

A generic qualitative focus group design was applied. 17 participants accepted the invitation to attend focus group interviews after completing the intervention. Five focus groups were conducted in total.

RESULTS

The qualitative analysis generated one overarching theme, named the benefit of meeting peers with a lived experience of T1D and body image concerns, and four themes: the need for an integrated focus on diabetes, personal relevance, providing sufficient balance between structure and flexibility and enabling a different perspective.

CONCLUSION

Results show overall positive feedback regarding the content and structure of the intervention, and underline the importance of targeting preventive efforts to specific risk groups.

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 Disturbed Eating Behaviors Underlying Body Weight Differences in Patients Affected by Endometriosis: Preliminary Results from an Italian Cross-Sectional Study

This study aimed to characterize the prevalence of eating disorders (EDs), disturbed eating behaviors (DEBs), and emotional eating attitudes (EEAs) among patients affected by endometriosis in order to understand a potential crosslink between this impacting gynecological disease and a Body Mass Index shift. A total of 30 patients were recruited at an endometriosis outpatient clinic in Bologna and were assessed by using standardized instruments and specific questionnaires for EDs, DEBs, and EEAs. Sociodemographic information and endometriosis clinical features and history information were collected by adopting a specific questionnaire. Retrospective reports of lifetime Body Mass Index (BMI) changes, current BMI, peak pain severity during the last menstrual period, and the average of pain intensity during the last intermenstrual period were used for a correlation with the mean score from eating-behavior scales' assessment. The preliminary results indicate that, although only 3.33% of endometriosis patients are affected by ED, statistically significant differences at the mean scores of DEBs and EEAs assessment scales were found by stratifying patients on the basis of BMI levels at risk for infertility and coronary heart disease and on the basis of moderate/severe pain levels. The enrichment of the sample size and the recruitment of the control group to complete the study enrollment will allow us to investigate more complex and strong correlation findings and to assess the prevalence of EDs among endometriosis patients.

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).

Depression in Diabetic Patients: What Is the Link With Eating Disorders? Results of a Study in a Representative Sample of Patients With Type 1 Diabetes

Background and Purpose

Comorbidity between diabetes and depression, and diabetes and eating disorders (ED) conveys significant diagnostic, clinical and therapeutic implications. The present study was conducted on a sample of adult outpatients affected by Type 1 Diabetes (T1DM) to assess lifetime prevalence of ED; current prevalence of depression and Disturbed Eating Behaviors (DEB) and their impact on glycemic control. We hypothesized that patients with depression would have higher rates of lifetime ED and current DEB. We hypothesized a significant and independent association between DEB and the prevalence of depression.

Materials and Methods

The study was carried out using a cross-sectional design in a sample of 172 diabetic patients with T1DM aged from 17 to 55 years. Lifetime prevalence of ED according to DSM-5 criteria was assessed by means of the Module H modified of the Structured Clinical Interview for DSM-IV Axis I Disorder (SCID-I). The following questionnaires were used: Beck Depression Inventory-IA version (BDI-IA) and Diabetes Eating Problems Survey-Revised (DEPS-R), to assess respectively the current presence of depression and DEB. Socio-demographic, clinical, and laboratory data were also collected.

Results

High rates of depression (35.5%) and DEB (19.2%) were observed in our sample of 172 adult outpatients with T1DM. Lifetime history of ED was present in 20.9% of the sample and was more frequently diagnosed in patients with current depression (34.4% vs. 13.9%, p = 0.002). Higher levels of DEB at DEPS-R significantly increased the odds of depression (adjOR: 1.09; 95% CI: 1.03-1.15; p = 0.003). The presence of DEB was associated with poor glycemic control. On the other hand, no association was found between depression and metabolic compensation.

Conclusion

Adult patients with T1DM and depression should be screened for ED and DEB. Treating DEB could positively impact both mood and glycemic control in this population. Further studies should be carried out on a larger patient population using a longitudinal design and an accurate method of evaluation to explore the complex relationship between diabetes, depression, ED, and DEB. Future research should investigate treatment strategies for DEB in T1DM patients and their impact on both psychopathological and metabolic outcomes.

Type 1 Diabetes Mellitus and Risks of Major Psychiatric Disorders: A Nationwide Population-Based Cohort Study

BACKGROUND

The temporal association between type 1 diabetes mellitus (T1DM) and major psychiatric disorders, including schizophrenia, major affective disorder, autism spectrum disorder (ASD), and attention-deficit hyperactivity disorder (ADHD), remains elusive.

METHODS

The specialized databases of catastrophic diseases and mental disorders and the longitudinal health insurance database of Taiwan National Health Insurance Research Database were used in current study. A total of 6,226 patients with T1DM and 62,260 age- and sex-matched controls were recruited between 2001 and 2010 and were followed until the end of 2011 for the identification of diagnoses of schizophrenia (International Classification of Clinical Diseases, Ninth Edition, Clinical Modification [ICD-9-CM] code: 295), bipolar disorder (ICD-9-CM codes: 296 except 296.2x, 296.3x, 296.9x, and 296.82), major depressive disorder (ICD-9-CM codes: 296.2x and 296.3x), ASD (ICD-9-CM code: 299), and ADHD (ICD-9-CM code: 314).

RESULTS

Cox regression analysis revealed increased hazard ratios of schizophrenia (12.28), bipolar disorder (13.80), major depressive disorder (10.41), ASD (14.52), and ADHD (8.19) in patients with T1DM compared with controls.

DISCUSSION

Our findings indicate the importance of clinicians closely monitoring the mental health condition of children, adolescents, and adults with T1DM. Additional studies should be conducted to elucidate the definite pathomechanisms of comorbidities between T1DM and major psychiatric disorders.

Insulin Restriction or Omission in Type 1 Diabetes Mellitus: A Meta-synthesis of Individuals' Experiences of Diabulimia

OBJECTIVE

Unique to individuals with insulin-dependent diabetes mellitus (IDDM) is a disordered eating behaviour whereby insulin is deliberately restricted or omitted. Despite growing research in this area, experiential perspectives of individuals remain understudied. Therefore, the purpose of this meta-synthesis was to explore the experiences of individuals with Type 1 Diabetes Mellitus (T1DM) by identifying, analysing and synthesising existing knowledge concerning their misuse of insulin for weight control.

DESIGN

Meta-aggregative techniques were employed to generate synthesised findings related to individuals' understanding and experience, physical and psychological impacts, support and treatment-related needs and experiences, noted in twelve studies.

RESULTS

A multifaceted relationship with the unique disordered eating behaviour, beyond weight control was identified. Many individuals experienced a wide range of diabetes-related complications from insulin restriction and omission alongside increased distress, loss of control and feelings of regret, guilt, and shame later in life. Almost all individuals valued peer support from those who shared a 'diabulimic' identity; peer support appeared more conducive to recovery than support from friends, family and formal support services, which were not uniformly supportive.

CONCLUSIONS

This meta-synthesis revealed valuable information from individuals with diabulimia which has widespread interdisciplinary implications and may provide useful guidance concerning the prevention and treatment of this unique behaviour. The results highlight the need for empathic, collaborative care, and proactive prevention and early intervention. Furthermore, the findings highlight the value of peer support in recovery, the need for increased knowledge among family and friends, training among multidisciplinary teams and support services, and crucially the development of evidence-based treatments informed by the behaviour as a unique distinct construct.

Feasibility of a virtually delivered eating disorder prevention program for young females with type 1 diabetes

OBJECTIVE

This study aimed to develop a virtual diabetes-specific version of the eating disorder (ED) prevention program the Body Project, and to assess feasibility and preliminary efficacy of this program for young females with type 1 diabetes.

METHOD

Young females with type 1 diabetes aged 16-35 years were invited to participate in the study. A total of 35 participants were allocated to five Diabetes Body Project groups (six meetings over 6 weeks) and completed pretest assessments; 26 participants completed all sessions and posttest assessments (<7 days after last meeting). Primary measures included ED risk factors and symptoms, and secondary outcomes included diabetes-specific constructs previously found to be associated with ED psychopathology (e.g., diabetes distress and illness perceptions).

RESULTS

The ease of recruitment, timely conduct of five groups, moderate drop-out rate and appreciation of the intervention by participants indicated that the Diabetes Body Project is feasible. Meaningful reductions occurred on the primary outcomes (i.e., ED psychopathology, body dissatisfaction, and thin ideal internalization) and on internalization of appearance ideals and appearance pressures at posttest (Cohen's d ranging from .63 to .83, which are medium to large effects). Small to medium effect sizes were found for diabetes illness perceptions and distress (.41 and .48, respectively).

DISCUSSION

The virtual Diabetes Body Project is a promising and much-needed intervention, worthy of more rigorous evaluation. A randomized controlled trial is warranted to determine its effectiveness compared with a control condition.

The Diabetes Eating Problem Survey-Revised (DEPS-R) in a Greek Adult Population with Type 1 Diabetes Mellitus: Model Comparison Supporting a Single Factor Structure

Type 1 diabetes mellitus (T1DM) patients occasionally develop disordered eating behaviors, leading to insulin manipulation without medical consultation, targeting to achieve weight control. In clinical practice, the Diabetes Eating Problem Survey-Revised Version (DEPS-R) questionnaire has been used to evaluate eating disorders in T1DM patients. This study was conducted to validate the factor structure of the Greek version of DEPS-R using Confirmatory Factor Analysis (CFA), to investigate its reliability and convergent validity in Greek T1DM adults and to compare a single factor DEPS-R model with multiple factor models. Participants were 103 T1DM adults receiving insulin, who responded to DEPS-R. Their anthropometric, biochemical and clinical history data were evaluated. The sample presented good glycemic control and 30.1% scored above the established DEPS-R cut-off score for disturbed eating behavior. CFA results revealed that the data fit well to the factor models. The DEPS-R scale had good reliability and was positively linked to BMI, HbA1c, total daily dose and time in range. Model comparison supported the superiority of the 1-factor model, implying that Greek clinicians and practitioners might not have to consider individualized treatment based on various scores across different subscales but they can adopt a single DEPS-R score for an easy and efficient screening for disordered eating.

Disordered Eating Behaviors Among Italian Adolescents with Type 1 Diabetes: Exploring Relationships with Parents' Eating Disorder Symptoms, Externalizing and Internalizing Behaviors, and Body Image Problems

The purpose of this study is to examine associations of disordered eating behaviors (DEBs) with body image problems, parents' eating disorder symptoms, and emotional and behavioral problems among adolescents with type 1 diabetes (T1D). 200 adolescents (M age = 15.24 ± 1.45 years) with T1D completed a self-report measure of DEBs and body ideal internalization, and their parents completed self-report measures of parents' eating problems and child's psychological symptoms. Seventy-three (36.5%) adolescents were DEPS-r-positive (scores ≥ 20), with higher rates among girls (χ² = 9.034, p = .003). Adolescents with T1D and DEBs reported lower SES, worse metabolic control, higher zBMI (p < .001), more eating disorder symptoms, more body image problems, and more emotional and behavioral problems than adolescents with T1D but no DEBs (all p < .05). Parents of adolescents with DEBs showed higher levels of bulimia (p = .028) than parents of adolescents without DEBs. In both genders, pressure to conform to societal norms about body image (p < .01) and externalization symptoms (p < .05) emerged as significant predictors of DEBs. Findings suggest that adolescents with T1D and DEBs showed an alarming psychological condition, with higher level of body image and more emotional and behavioral problems.

Instrument Context Relevance Evaluation, Translation, and Psychometric Testing of the Diabetes Eating Problem Survey-Revised (DEPS-R) among People with Type 1 Diabetes in China

Background: People with type 1 diabetes are susceptible to disordered eating behaviors. The American Diabetes Association recommends using the Diabetes Eating Problem Survey-Revised (DEPS-R) to screen them. There is no validated diabetes-specific screening measure in China. The objectives were to adapt DEPS-R into Mandarin Chinese and to test its psychometric properties among youths and adults with type 1 diabetes in China, respectively. Methods: This study was conducted in two phases. Phase 1 included context relevance evaluation and instrument translation. Phase 2 was psychometric testing of reliability and construct validity among 89 youths (8~17 years old) and 61 adults with type 1 diabetes. Result: The Context Relevance Index and Translation Validity Index of this instrument were good. Strong internal consistency reliability correlations and convergent validity were demonstrated among youths and adults. Discussion: The Chinese version of the DEPS-R is a valid and reliable tool for screening disordered eating behaviors in Chinese youths and adults with type 1 diabetes. The Context Relevance Index is advocated to evaluate the difference between the context in which an instrument was originally developed and the target context.

Psychometric properties of the Norwegian version of the Patient Health Questionnaire-9 (PHQ-9) in a large female sample of adults with and without eating disorders

BACKGROUND

Internationally, the Patient Health Questionnaire-9 (PHQ-9) is commonly used to assess the frequency and severity of depressive symptoms. However, psychometric properties of the Norwegian version of the PHQ-9 have only been assessed in adolescents. We present normative data for women and an evaluation of the psychometric properties (internal consistency, convergent validity, and factor structure) of the Norwegian PHQ-9 among women with and without eating disorders (ED).

METHODS

In this case-control study, a total of 793 females aged 18-78 years (mean 30.39; SD 9.83) completed an online self-report assessment. Measures included the ED100K and Eating Disorder Examination Questionnaire (EDE-Q) to assess ED psychopathology, and the Generalized Anxiety Disorder (GAD) scale and Difficulties in Emotion Regulation Scale Short Form (DERS-SF) to assess symptoms of anxiety and emotion regulation deficits. Participants were categorized into three groups, i.e., previous ED (19.7%, n = 148), current ED (36.3%, n = 272), and no history of ED (44.0%, n = 330), based on self-reported scores on the ED 100 K and the EDE-Q.

RESULTS

Mean PHQ-9 total score for those with a previous history of ED was 10.67 (SD 6.33), for those with a current ED 16.61 (SD 5.84), and for those with no lifetime history of ED 6.83 (SD 5.58). Excellent internal consistency was demonstrated by Cronbach's alpha's for individuals with a previous ED (.88), for individuals with a current ED (.86), and for individuals with no history of ED (.88). Acceptable convergent validity was indicated based on significant correlations between the PHQ-9 and GAD-7 and DERS-SF. Confirmatory Factor Analyses revealed a mediocre fit for a one-factor structure of the PHQ-9, regardless of diagnostic status.

CONCLUSIONS

The psychometric properties of the Norwegian version of the PHQ-9 are acceptable across females with and without ED, and the PHQ-9 can be recommended for use in clinical ED settings and for people without mental disorders.

Obesity in Patients with Type 1 Diabetes: Links, Risks and Management Challenges

Obesity affects large numbers of patients with type 1 diabetes (T1D) across their lifetime, with rates ranging between 2.8% and 37.1%. Patients with T1D and obesity are characterized by the presence of insulin resistance, of high insulin requirements, have a greater cardiometabolic risk and an enhanced risk of developing chronic complications when compared to normal-weight persons with T1D. Dual treatment of obesity and T1D is challenging and no specific guidelines for improving outcomes of both glycemic control and weight management have been established for this population. Nevertheless, although evidence is scarce, a comprehensive approach based on a balanced hypocaloric diet, physical activity and cognitive behavioral therapy by a multidisciplinary team, expert in both obesity and diabetes, remains as the best clinical practice. However, weight loss responses with lifestyle changes alone are limited, so in the "roadmap" of the treatment of obesity in T1D, it will be helpful to include anti-obesity pharmacotherapy despite at present there is a lack of evidence since T1D patients have been excluded from anti-obesity drug clinical trials. In case of severe obesity, bariatric surgery has proven to be of benefit in obtaining a substantial and long-term weight loss and reduction in cardiovascular risk. The near future looks promising with the development of new and more effective anti-obesity treatments and strategies to improve insulin resistance and oxidative stress. Advances in precision medicine may help individualize and optimize the medical management and care of these patients. This review, by gathering current evidence, highlights the need of solid knowledge in all facets of the treatment of patients with obesity and T1D that can only be obtained through high quality well-designed studies.

A relação entre a mulher com diabetes e o seu corpo: o risco da diabulimia

Resumo Objetivo compreender a relação que as mulheres com diabulimia têm com o corpo. Método pesquisa qualitativa, desenvolvida com o Método da História Oral Temática, com quatro mulheres entre 18 e 30 anos que autorreferiram diabulimia. Resultados a relação das mulheres com o seu corpo foi pautada pela pressão social de magreza feminina que distorce a autoimagem, gera insatisfação com o corpo e a diminuição da autoestima. A perda de peso é proporcionalmente associada ao aumento da aceitação social e justifica a utilização de métodos deletérios à saúde como a diminuição da dose ou a suspensão do uso de insulina. As narradoras demonstraram conhecer os riscos, mas admitiram repeti-la em determinados contextos. Considerações finais e implicações para a prática o desejo que as mulheres com Diabetes Mellitus têm de perder peso precisa ser incorporado às estratégias de cuidado com a atenção dos profissionais da saúde à subjetividade, atuando para reconhecer e prevenir os transtornos alimentares em mulheres com diabetes e minimizar a adoção de ações prejudiciais à saúde.

The impact of psychological aspects, age, and BMI on eating disorder psychopathology among adult males and females with type 1 diabetes

This study investigated correlates of eating disorder (ED) psychopathology among adults with type 1 diabetes (T1D). A total of 282 males (n = 112) and females (n = 170) with T1D (18–79 years) participated. Overall, psychological aspects (i.e. illness perceptions, coping strategies, insulin beliefs, anxiety, and depression) were associated with ED psychopathology. Associations were generally stronger among females than males. In a regression model, age, BMI, personal control, and anxiety explained 51% of the variance in ED psychopathology among females, whereas BMI, personal control, and anxiety explained 47% of the variance among males. Greater clinical awareness of health psychological aspects may contribute to reduce the risk of developing ED.

Diabetes and eating disorders: an exploration of 'Diabulimia'

Background

‘Diabulimia’ is the term given to the deliberate administration of insufficient insulin for the purpose of weight loss. Although Diabulimia can be life-threatening and prevalence rates in diabetes are high, there is a lack of research for how to effectively support people with the condition. This exploratory study aimed to provide much-needed information to healthcare professionals and guide the focus for future research.

Methods

Forty-five individuals with Type 1 diabetes mellitus (T1DM) and a history of insulin misuse completed an online questionnaire. This included an assessment of their eating disorder psychopathology with the Eating Disorder Examination Questionnaire (EDE-Q) and 16 open-ended questions exploring their experience of Diabulimia. The responses to the open-ended questions were analysed using thematic analysis.

Results

The average global EDE-Q score was 3.96 (1.21), which is consistent with eating disorder populations. Common themes identified were concerns about weight, difficulty coping with diabetes, past trauma, and the importance of relationships. Experiences with health professionals were overwhelmingly negative. Most participants had experienced serious medical intervention due to Diabulimia and were fully aware of the consequences of insulin restriction.

Conclusions

Overall, individuals believed that a greater awareness of Diabulimia and more training for healthcare professionals is needed. While education on insulin misuse may be a necessary first step in treatment, psychological support is crucial. To deliver effective treatment, clinicians should be aware of the specific issues facing those with Diabulimia. The current study identified themes that clinicians may find useful to consider.

Body Image Problems and Disordered Eating Behaviors in Italian Adolescents With and Without Type 1 Diabetes: An Examination With a Gender-Specific Body Image Measure

Objective

To examine body image problems and their associations with disordered eating behavior in adolescents with type 1 diabetes and well-matched healthy peers.

Methods

Using a cross-sectional design, 183 adolescents with type 1 diabetes (13.02–18.05 years) were recruited from diabetes centers in southern Italy and compared to healthy peers matched for age and gender. Participants completed self-report measures of disordered eating behaviors (DEPS-r and EDI-3RF) and a gender-specific body image problem questionnaire (SATAQ-4R). Socio-demographic and clinical data (zBMI, HbA1c, and disease duration) were also collected. Hierarchical multiple linear regression analyses were computed to determine the relative importance of diabetes variables and body image problems on participants’ disordered eating behaviors after controlling for demographic variables.

Results

Adolescents with type 1 diabetes showed diabetes-specific eating problems in 37.7% of cases and had more eating problem symptoms (assessed as drive for thinness and bulimia) than healthy peers. Male adolescents with type 1 diabetes did not display more body image problems (p > 0.05); females with type 1 diabetes compared to females in the control group were found to be more pressured by family (p = 0.025) but less by media (p = 0.022) to improve their appearance and attain a thin body. zBMI and body image problems contributed to a significant increase in disordered eating behavior risk both in male and female adolescents with diabetes and in healthy peers (zBMI 0.213 < β < 0.426, p < 0.05; body image 0.243 < β < 0.572, p < 0.05). None of the variables analyzed were found to significantly predict male bulimic symptoms (all β < 0.296, p > 0.05).

Conclusion

Since in adolescence type 1 diabetes and insulin therapy may increase the risk of weight gain and promote focus and attention on the body and thus contribute to the development of body image problems and disordered eating behaviors, continuity of medical, nutritional, and psychological care is needed.

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.

Screening and identification of disordered eating in people with type 1 diabetes: A systematic review

People with Type 1 diabetes (T1D) have been shown to be an at-risk group for the development of disordered eating behaviours, however, the validity of tools used to assess disordered eating behaviours in T1D is unclear. This review aimed to identify tools used to screen or identify disordered eating behaviours and eating disorders in people with T1D, and evaluate the validity and reliability of these tools. A systematic search strategy was conducted to October 2019 according to the PRISMA guidelines. The search strategy retrieved 2714 articles, with 100 articles describing 90 studies included in the review. Studies were predominantly conducted in adolescent females in clinical settings. Forty-eight individual tools were used across retrieved studies. Overall, the quality of tools reported in included articles was poor, with high risk of bias due to the use of non-validated tools (n = 44 articles) and few studies comparing to the reference standard (n = 10 articles) of a diagnostic interview. This review shows that a variety of tools have been used to screen and identify disordered eating behaviours and eating disorders in people with T1D. Future research including comparison to a gold standard diagnostic interview is warranted to further evaluate the validity and reliability of available tools.

25 Years of psychological research investigating disordered eating in people with diabetes: what have we learnt?

Disordered eating is a serious and under-recognized problem in people with diabetes. This narrative review summarizes the research contributions made by psychological science over the past 25 years to the study of disordered eating in people with type 1 or type 2 diabetes, and identifies gaps and future directions relevant to both healthcare professionals and researchers. Key focus areas of psychological research investigating disordered eating in people with diabetes have been: (1) defining and classifying types of disordered eating; (2) identifying demographic, diabetes-specific and psychosocial correlates of disordered eating, and developing theoretical models of disordered eating in people with type 1 diabetes; (3) identifying the physical and psychosocial consequences of disordered eating; and (4) developing screening measures to identify disordered eating in people with type 1 diabetes. Psychological science has made significant contributions over the past 25 years to our understanding of the nature of this problem and the multiple factors which may interrelate with disordered eating in people with diabetes. Key areas for further attention include: (1) a better definition of disordered eating subtypes in people with type 1 diabetes; (2) characterizing disordered eating in people with type 2 diabetes; and (3) developing multidisciplinary, evidence-based prevention and treatment interventions for comorbid disordered eating and diabetes.

Exploring emotional dysregulation characteristics and comorbid psychiatric disorders in type 1 diabetic children with disordered eating behavior risk

OBJECTIVE

To investigate emotional dysregulation and psychiatric comorbidities associated with DEB-risk in children with type 1 diabetes mellitus (T1DM).

METHODS

A total of 75 children with T1DM aged between 8 and 19 were evaluated by K-SADS-PL to assess psychiatric diagnosis. DEB-risk was evaluated via Diabetes Eating Problem Survey-Revised (DEPS-R). Besides, all participants completed the Childhood Depression Inventory (CDI), Difficulties in Emotion Regulation Scale (DERS), and The State-Trait Anxiety Inventory (STAI).

RESULTS

DEPS-R-positive (≥20) was detected in 28% of the participants. The only diagnostic difference was a significantly higher frequency of ED in DEPS-R-positive than DEPS-R-negative (OR = 8.5, CI = 1.94-37.1, p = .004). DEPS-R-positive cases had significantly higher scores of the CDI, STAI, DERS, and the subscales of Goals, Impulse, and Strategies of DERS (CDI U = 266.500, p = .001; STAI U = 288.500,p = .001; DERS U = 229.000, p = .001, Goals U = 283.500, p = .008, Impulse U = 274.000, p = .005, Strategies U = 281.500, p = .007). In stepwise linear regression analysis, STAI-state and DERS scores significantly determined DEB-risk (STAI: β = 0.363, t(60) = 2.33, p = .02, DERS: β = 0.240, t(60) = 4.14, p < .001).

CONCLUSION

This cross-sectional study showed that DEPS-R-positive cases have an 8.5-fold increased risk for ED. DEPS-R-positive ones have difficulties in regulating their emotions and they are incapable of accessing emotion regulation strategies, engaging in goal-directed behavior while under difficult emotions, and impulse control. It can be beneficial for child psychiatrists to screen first for ED in DEPS-R-positive cases who are referred by child endocrinologist. They should also take into consideration anxiety levels and problems in emotion dysregulation in the DEPS-R-positive cases.

Carbohydrate Intake in the Context of Exercise in People with Type 1 Diabetes

Although the benefits of regular exercise on cardiovascular risk factors are well established for people with type 1 diabetes (T1D), glycemic control remains a challenge during exercise. Carbohydrate consumption to fuel the exercise bout and/or for hypoglycemia prevention is an important cornerstone to maintain performance and avoid hypoglycemia. The main strategies pertinent to carbohydrate supplementation in the context of exercise cover three aspects: the amount of carbohydrates ingested (i.e., quantity in relation to demands to fuel exercise and avoid hypoglycemia), the timing of the intake (before, during and after the exercise, as well as circadian factors), and the quality of the carbohydrates (encompassing differing carbohydrate types, as well as the context within a meal and the associated macronutrients). The aim of this review is to comprehensively summarize the literature on carbohydrate intake in the context of exercise in people with T1D.

Disordered eating behaviours, body image and social networking in a type 1 diabetes population

The purpose of this study was twofold: to examine predictors of disordered eating behaviours and body image dissatisfaction, including social networking, among type 1 diabetes population, and to qualitatively explore the relationship between type 1 diabetes management and body image. A convenience sample of 121 type 1 diabetes patients (F = 106; M_age = 36 ± 6.5) was collected via online questionnaires, of which 98 patients responded to two open-ended questions. Young age and negative body image explained 58.8 per cent of disordered eating variance, while body weight and social networking negatively contributed to poor body image (29.9%). Qualitative analysis revealed three themes: no control over body weight, limitation in clothing options and discomfort towards medical equipment.

Association of Area Deprivation and Diabetic Ketoacidosis Readmissions: Comparative Risk Analysis of Adults vs Children With Type 1 Diabetes

OBJECTIVE

Recurrent diabetic ketoacidosis (DKA) is associated with mortality in adults and children with type 1 diabetes (T1D). We aimed to evaluate the association of area deprivation and other patient factors with recurrent DKA in pediatric patients compared with adults.

RESEARCH DESIGN AND METHODS

This cross-sectional study used the Maryland Health Services Cost Review Commission's database to identify patients with T1D admitted for DKA between 2012 and 2017. Area deprivation and other variables were obtained from the first DKA admission of the study period. Multivariable logistic regression analysis was performed to determine predictors of DKA readmissions. Interactions (Ints) evaluated differences among the groups.

RESULTS

There were 732 pediatric and 3305 adult patients admitted with DKA. Area deprivation was associated with higher odds of readmission in pediatric patients than in adults. Compared with the least deprived, moderately deprived pediatric patients had an OR of 7.87-(95% CI, 1.02 to 60.80) compared with no change in odds in adults for four or more readmissions (Pint < 0.01). Similar odds were observed in the most deprived pediatric patients, which differed significantly from the OR of 2.23 (95% CI, 1.16 to 4.25) in adults (Pint of 0.2). Moreover, increasing age, female sex, Hispanic ethnicity, and discharge against medical advice conferred a high odds for four or more readmissions in pediatric patients compared with adults.

CONCLUSION

Area deprivation was predictive of recurrent DKA admissions, with a more pronounced influence in pediatric than adult patients with T1D. Further studies are needed to understand the mechanisms behind these associations and address disparities specific to each population.

Zebrafish models of diabetes-related CNS pathogenesis

Diabetes mellitus (DM) is a common metabolic disorder that affects multiple organ systems. DM also affects brain processes, contributing to various CNS disorders, including depression, anxiety and Alzheimer's disease. Despite active research in humans, rodent models and in-vitro systems, the pathogenetic link between DM and brain disorders remains poorly understood. Novel translational models and new model organisms are therefore essential to more fully study the impact of DM on CNS. The zebrafish (Danio rerio) is a powerful novel model species to study metabolic and CNS disorders. Here, we discuss how DM alters brain functions and behavior in zebrafish, and summarize their translational relevance to studying DM-related CNS pathogenesis in humans. We recognize the growing utility of zebrafish models in translational DM research, as they continue to improve our understanding of different brain pathologies associated with DM, and may foster the discovery of drugs that prevent or treat these diseases.

Disturbed eating, illness perceptions, and coping among adults with type 1 diabetes on intensified insulin treatment, and their associations with metabolic control

This study investigated associations between psychological aspects and metabolic control among adults with type 1 diabetes ( n = 282). Linear regression analyses demonstrated that the illness perception personal control and the coping strategy seeking emotional social support explained 23.2 percent of the variance in hemoglobin A1c among females ( β = 0.40, p < 0.001 and β = −0.22, p < 0.01, respectively). Among males, only personal control remained significant, explaining 13.9 percent of the variance in hemoglobin A1c ( β = 0.37, p < 0.001). The associations between psychological correlates and hemoglobin A1c indicate that addressing such aspects clinically may facilitate metabolic control, thereby potentially contributing to reduce the risk of complications.

Parental assessment of disordered eating behaviors in their children with type 1 diabetes: A controlled study

OBJECTIVE

The purpose of this research is to examine the presence of disordered eating behaviors (DEBs) in youths with type 1 diabetes (T1D) according to their parents' evaluations. The roles of demographic and diabetes-related variables were also analyzed.

METHODS

In 54 patients with T1D (aged 10.07-15.08) and in 54 age- and gender-matched healthy controls, DEBs were assessed using a parent-report standardized measure. BMI was calculated from height and weight. Glycemic control was assessed based on the most recent glycosylated hemoglobin value (HbA1c). The association of demographic and clinical factors with DEBs was evaluated through correlation and linear regression analyses.

RESULTS

DEBs were observed more frequently in participants with T1D (33.3%) than in controls (11%) (χ² = 6.501, p = .04). The clinical sample obtained a higher score than controls in PEBEQ total score (t(106) = 2.464, p = .01), as well as in the Exaggerated interest in food (t(106) = 2.723, p = .008) and Rejection/disinterest in food subscales (t(106) = 2.216, p = .01). No gender differences were observed. In participants with T1D, but not in controls, PEBEQ total score was positively correlated with age (r = 0.203, p = .04), HbA1c (r = 0.335, p = .01), and zBMI (r = 0.298, p = .002); HbA1c (standardized beta =0.284, p = .04) was found to uniquely predict the PEBEQ total score.

CONCLUSION

Parents' evaluations may contribute to prompt detection of DEBs, which is crucial in developing appropriate strategies for timely intervention, especially during adolescence.

Psychometric properties and factor structure of the diabetes eating problem survey - revised (DEPS-R) among adult males and females with type 1 diabetes

BACKGROUND

Although an increasing amount of research has now established good psychometric properties and a three-component factor structure of the Diabetes Eating Problem Survey - Revised (DEPS-R) in pediatric samples with type 1 diabetes (T1D), research using adult samples has been limited and divergent. This study therefore aimed to investigate psychometric properties and test a three-factor model of the DEPS-R among adults with T1D.

METHODS

A total of 282 adults with T1D aged 18-79 years participated in the study. Measures included the DEPS-R, the Eating Disorder Examination Questionnaire (EDE-Q), and clinical data from the Norwegian Quality Improvement of Laboratory Examinations (NOKLUS) system.

RESULTS

The DEPS-R total mean score (SD) for the total sample, males, and females were 13.8 (9.2), 11.2 (7.8), and 15.6 (9.6) respectively. Good fit indices for the confirmatory factor analysis were found. The Cronbach's alpha of the DEPS-R was .84, suggesting good internal consistency. The DEPS-R correlated significantly with the EDE-Q among both males (.52, p < .01) and females (.68, p < .001). Also, the DEPS-R correlated significantly with BMI in both genders (.33, p < .001 in females and .35, p < .001 in males). HbA1c correlated significantly with the DEPS-R in females (.27, p < .01), but not in males.

CONCLUSIONS

Good fit for a three-factor structure of the DEPS-R was confirmed. Further, the DEPS-R demonstrated good psychometric properties among adults with T1D, and can be recommended for clinical use for this patient group.
