Eating disorders in young women with type 1 diabetes mellitus

Evaluation of a novel eating disorder prevention program for young women with type 1 diabetes: A preliminary randomized trial

OBJECTIVE

Evaluate whether the Body Project prevention program adapted for young women with type 1 diabetes (Diabetes Body Project) reduces eating disorder (ED) risk factors and symptoms.

METHODS

Young women (aged 15-30) at high-risk for EDs due to having type 1 diabetes and body image concerns (N = 55) were randomized to virtually delivered Diabetes Body Project groups or an educational control condition, completing measures at pretest, posttest, and 3-month follow-up.

RESULTS

Diabetes Body Project versus the control participants showed significantly greater reductions in thin-ideal internalization, body dissatisfaction, diabetes distress, diabetes eating pathology, and ED symptoms by posttest, and greater reductions in diabetes eating pathology and ED symptoms, and greater improvements in quality of life by 3-month follow-up, which were medium to large effects (d's ranged from -0.43 to -0.90). Although control participants showed a worsening of glycemic control (time in range) verses Diabetes Body Project participants, this difference was non-significant (d = 0.26).

CONCLUSIONS

Virtually delivered Diabetes Body Project decreased ED risk factors and symptoms in young women with type 1 diabetes. A well powered randomized controlled trial is warranted to evaluate this intervention over longer follow-up.

Depression, anxiety, eating problems, and diabulimia risk in adolescents with type 1 diabetes: a case-control study

OBJECTIVES

Type 1 diabetes (T1D) causes psychological distress, negatively impacting normal childhood activities. Depression, anxiety disorders, and eating problems are commonly observed in this population.

METHODS

The study population consisted of 40 adolescents (22 females and 18 males) who had been diagnosed with T1D and 41 healthy adolescents (21 females and 20 males). The aim of this study was to compare adolescents with T1D to healthy controls in terms of depression, anxiety, and eating problems and subsequently examine the T1D group in relation to the risk of diabetes-specific eating disorders. Eating Attitudes Test (EAT-40), Revised Children's Anxiety and Depression Scale (RCADS), and Diabetes Eating Problem Survey - Revised (DEPS-R) scales were used to compare the case and control groups.

RESULTS

The case group exhibited significantly higher scores in EAT-40 total score, RCADS parent form major depressive disorder (MDD), social anxiety disorder (SAD), generalized anxiety disorder (GAD), panic disorder (PD), total anxiety score, total scale scores, RCADS child form MDD, PD, and total scale scores compared to the control group. Individuals at high risk of diabetes-specific eating disorder within the case group demonstrated significantly higher RCADS (child and parent form) MDD scores and RCADS parent form separation anxiety (SA) and total scale scores. Binary logistic regression analysis revealed that the RCADS parent form total scale score could predict DEPS-R.

CONCLUSIONS

Routine screening of children and adolescents diagnosed with T1D for depression, anxiety, and eating disorder risk may facilitate early detection of possible psychopathologies, allowing for early intervention to address factors that may disrupt treatment adherence. Further longitudinal studies with larger samples are needed to investigate psychopathologies, particularly eating disorders, in children and adolescents with T1D.

A thematic analysis of YouTube comments on a television documentary titled 'Diabulimia: The World's most dangerous eating disorder'

AIM

Omitting insulin for fear of weight gain is a type of disordered eating (also labelled as diabulimia) common in type 1 diabetes (T1D) and is associated with a worse biomedical prognosis but is not a formally recognised condition. This research explored the public's opinion of diabulimia as a condition as presented in a television documentary.

METHODS

We conducted a coding reliability thematic analysis using NVivo software of the original comments to a YouTube documentary 'Diabulimia: The World's Most Dangerous Eating Disorder' between 24 September 2017 and 16 June 2020.

RESULTS

Of 1424 original comments, 1264 were eligible and uploaded into NVivo 12. The commenters were people with T1D, family and friends, health care professionals, and the wider public who collectively had questions, personal stories and/or opinions. Three main themes were discerned: lack of awareness of diabulimia as a condition; the importance of support; diabulimia as a psychiatric condition in the diabetes setting.

CONCLUSION

This analysis of social media comments found that there is a lack of awareness of diabulimia amongst patients, their families and friends, and healthcare professionals and that there were many commenters who had the experience of disordered eating with T1D. This study has reported on themes that suggest there may be an eating disorder specifically in people with T1D and that further work is needed to understand the diagnostic criteria for diabulimia in order to develop effective treatments.

Food-Related Quality of Life in Children and Adolescents With Crohn's Disease

BACKGROUND

Food-related quality of life (FRQoL) encompasses the psychosocial elements of eating and drinking. The FRQoL of children and adolescents with inflammatory bowel disease has not yet been assessed. This study aimed to evaluate the utility of the validated FR-Qol-29 instrument in children with Crohn's disease (CD).

METHODS

Children diagnosed with CD, a shared home environment healthy sibling, and healthy control subjects 6 to 17 years of age were recruited to this single-center, prospective, cross-sectional study. Children or their parent or guardian completed the FR-QoL-29 instrument. Internal consistency was assessed by completing Cronbach's α. Construct validity was established by correlating the CD FR-QoL-29 sum scores with the Physician Global Assessment and Pediatric Crohn Disease Activity Index scores. The discriminant validity was analyzed using a 1-way analysis of variance, and a Spearman's correlation coefficient test was completed to identify any correlations associated with FRQoL.

RESULTS

Sixty children or their parent or guardian completed the FR-QoL-29 instrument (10 children in each subgroup). The internal consistency was excellent (Cronbach's α = 0.938). The mean FR-QoL-29 sum scores were 94.3 ± 27.6 for CD, 107.6 ± 20 for siblings, and 113.7 ± 13.8 for control subjects (P = .005). Those with higher disease activity had worse FRQoL (Physician Global Assessment P = .021 and Pediatric Crohn Disease Activity Index P = .004). Inflammatory bowel disease FR-QoL-29 sum scores correlated with weight (P = .027), height (P = .035), body mass index (P = .023), and age (P = .015).

CONCLUSIONS

FRQoL is impaired in children with CD. Healthy siblings also have poorer FRQoL than control subjects. Several clinical factors are associated with poorer FRQoL in children with CD including age and level of nutritional risk (weight, height, and body mass index). Further research is required validate these findings and to develop strategies for the prevention or treatment of impaired FRQoL in children with CD.

Management of eating disorders for people with higher weight: clinical practice guideline

INTRODUCTION

The prevalence of eating disorders is high in people with higher weight. However, despite this, eating disorders experienced by people with higher weight have been consistently under-recognised and under-treated, and there is little to guide clinicians in the management of eating disorders in this population.

AIM

The aim of this guideline is to synthesise the current best practice approaches to the management of eating disorders in people with higher weight and make evidence-based clinical practice recommendations.

METHODS

The National Eating Disorders Collaboration Steering Committee auspiced a Development Group for a Clinical Practice Guideline for the treatment of eating disorders for people with higher weight. The Development Group followed the 'Guidelines for Guidelines' process outlined by the National Health and Medical Research Council and aim to meet their Standards to be: 1. relevant and useful for decision making; 2. transparent; 3. overseen by a guideline development group; 4. identifying and managing conflicts of interest; 5. focused on health and related outcomes; 6. evidence informed; 7. making actionable recommendations; 8. up-to-date; and, 9. accessible. The development group included people with clinical and/or academic expertise and/or lived experience. The guideline has undergone extensive peer review and consultation over an 18-month period involving reviews by key stakeholders, including experts and organisations with clinical academic and/or lived experience.

RECOMMENDATIONS

Twenty-one clinical recommendations are made and graded according to the National Health and Medical Research Council evidence levels. Strong recommendations were supported for psychological treatment as a first-line treatment approach adults (with bulimia nervosa or binge-eating disorder), adolescents and children. Clinical considerations such as weight stigma, interprofessional collaborative practice and cultural considerations are also discussed.

CONCLUSIONS

This guideline will fill an important gap in the need to better understand and care for people experiencing eating disorders who also have higher weight. This guideline acknowledges deficits in knowledge and consequently the reliance on consensus and lower levels of evidence for many recommendations, and the need for research particularly evaluating weight-neutral and other more recent approaches in this field.

Pathological eating behaviours and risk of retinopathy in diabetes: a systematic review and meta-analysis

Background

Diabetes mellitus can cause several long-term macrovascular and microvascular complications including nephropathy, neuropathy, and retinopathy (DR). Several studies have reported positive associations between eating pathologies and DR; however, these studies have not been aggregated and sub-grouped into type of pathological eating behaviour, and the differences in risk according to type of eating behaviour is unknown. The aim of this review, therefore, was to aggregate risks of DR in populations with and without pathological eating behaviours, stratified according to eating behaviour.

Methods

A systematic review and meta-analysis was conducted. Major databases and grey literature were search from inception until 1/6/2021. Studies reporting the prevalence of pathological eating behaviours (against a control group with no pathological eating behaviours) in diabetic people with and without DR were included. Odds ratios were calculated from primary data.

Results

Seven studies with eight independent outcomes with a total of 1162 participants were included. The odds ratio of DR in the total pooled analysis was 2.94 (95%CI 1.86-4.64; p = <0.001; I2 = 29.59). Two types of eating behaviour yielded enough data for sub-group analysis. Eating disorder not otherwise specified yielded an odds ratio of 2.73 (95%CI 1.81-4.10; p = <0.001; I2 = 0.00), and binge eating disorder yielded an non-significant odds ratio of 0.92 (95%CI 0.31-2.77; p = 0.887;I2 = 0.00).

Discussion

The likelihood of DR increases almost three times in the presence of pathological eating behaviours. More studies are required to confirm this in clinical populations stratified by eating disorder. Practitioners working with people with diabetes should closely monitor eating behaviours to preclude this risk.

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.

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

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

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.

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

OBJECTIVE

To ascertain the association and coaggregation of eating disorders and childhood-onset type 1 diabetes in families.

RESEARCH DESIGN AND METHODS

Using population samples from national registers in Sweden (n = 2,517,277) and Demark (n = 1,825,920), we investigated the within-individual association between type 1 diabetes and eating disorders and their familial coaggregation among full siblings, half siblings, full cousins, and half cousins. On the basis of clinical diagnoses, we classified eating disorders into any eating disorder (AED), anorexia nervosa (AN) and atypical AN, and other eating disorder (OED). Associations were determined with hazard ratios (HRs) with 95% CIs from Cox regressions.

RESULTS

Swedish and Danish individuals with a type 1 diabetes diagnosis had a greater risk of receiving an eating disorder diagnosis (HR [95% CI] Sweden: AED 2.02 [1.80-2.27], AN 1.63 [1.36-1.96], OED 2.34 [2.07-2.63]; Denmark: AED 2.19 [1.84-2.61], AN 1.78 [1.36-2.33], OED 2.65 [2.20-3.21]). We also meta-analyzed the results: AED 2.07 (1.88-2.28), AN 1.68 (1.44-1.95), OED 2.44 (2.17-2.72). There was an increased risk of receiving an eating disorder diagnosis in full siblings in the Swedish cohort (AED 1.25 [1.07-1.46], AN 1.28 [1.04-1.57], OED 1.28 [1.07-1.52]); these results were nonsignificant in the Danish cohort.

CONCLUSIONS

Patients with type 1 diabetes are at a higher risk of subsequent eating disorders; however, there is conflicting support for the relationship between having a sibling with type 1 diabetes and an eating disorder diagnosis. Diabetes health care teams should be vigilant about disordered eating behaviors in children and adolescents with type 1 diabetes.

Admitted for an Eating Disorder: Challenges Clinical Psychologists Face in Working with Patients and Their Families on a Consultation-Liaison Service in a Tertiary Pediatric Hospital

Eating disorders are one of the most common causes of pediatric hospitalizations due to primary mental health diagnoses. The purpose of this article is to discuss the challenges clinical psychologists face in working with patients with eating disorders and their families during medical admissions. Using the Psychiatry Consultation Service at a tertiary pediatric academic medical center in the Northeast as a framework, authors present the responsibilities of clinical psychologists on this service and their role within the larger, interdisciplinary team. Topics addressed also include systemic challenges, medical and psychiatric comorbidities, and differential psychiatric diagnoses. Case examples are provided to highlight various challenges as well as potential solutions and approaches. Clinical implications, limitations, and directions for future research are also discussed.

High prevalence of disordered eating behavior in Danish children and adolescents with type 1 diabetes

OBJECTIVE

A higher prevalence of disordered eating behavior (DEB) has been demonstrated in children and adolescents with type 1 diabetes (T1D) compared to healthy aged-matched peers. DEB is associated with higher HbA1c levels and increased risk of developing complications to T1D. The aim of this study was to determine the prevalence of DEB in a Danish cohort of children and adolescents with T1D aged 11 to 19 years and to characterize them regarding metabolic control and relevant clinical data.

RESEARCH DESIGN AND METHODS

In a cross-sectional study, we determined the prevalence of DEB using the revised Diabetes Eating Problem Survey (DEPS-R) questionnaire. HbA1c and relevant clinical data were obtained at the time they filled in the questionnaire.

RESULTS

Hundred and ninety-two children and adolescents (46% girls) aged 11 to 19 years with T1D were included from the pediatric diabetes outpatient clinic. A total of 40 participants (21%) had DEB. The prevalence was higher among girls compared with boys (34.1% vs 8.9%) and those who had DEB were older (16.7 vs 15.0 years, P < .001), had longer duration of T1D (7.5 vs 4.9 years, P < .001), higher BMI Z-scores (1.2 vs 0.3, P < .001), higher HbA1c (72.8 (8.8%) vs 62.0 (7.8%) mmol/mol, P < .001), higher total cholesterol (4.6 mmol/L vs 4.2 mmol/L, P = .0048), and LDL (2.7 vs 2.3, P = .001) compared with those with no signs of DEB.

CONCLUSION

As in other countries, the prevalence of DEB is high in Danish adolescents with T1D. Early detection of DEB is essential to prevent short- and long-term complications to T1D.

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.

Causative factors of eating problems among adolescents with type 1 diabetes mellitus: A qualitative study

Adolescents with type 1 diabetes mellitus are prone to have eating problems. This study aimed to determine factors of eating problems among this population in University Malaya Medical Centre. Fifteen adolescents who scored more than 20 marks in the Diabetes Eating Problem Survey - Revised questionnaire were invited for an in-depth interview. Questions were asked based on their questionnaire's response. The interview sessions were recorded, transcribed verbatim, and thematic analysis was used. Five main themes emerged: pressure, physiological factor, psychological factor, patient's low compliances to insulin intake and food control and fear. Early referral to child psychologist would prevent it from developing.

Intuitive eating is associated with weight and glucose control during pregnancy and in the early postpartum period in women with gestational diabetes mellitus (GDM): A clinical cohort study

INTRODUCTION

High pre-pregnancy weight and body mass index (BMI) increase the risk of gestational diabetes mellitus (GDM) and diabetes after pregnancy. To tackle weight and metabolic health problems, there is a need to investigate novel lifestyle approaches. Outside of pregnancy, higher adherence to intuitive eating (IE) is associated with lower BMI and improved glycemic control. This study investigated the association between IE and metabolic health during pregnancy and in the early postpartum period among women with GDM.

METHODS

Two-hundred and fourteen consecutive women aged ≥18, diagnosed with GDM between 2015 and 2017 and completed the "Eating for Physical rather than Emotional Reasons (EPR)" and "Reliance on Hunger and Satiety cues (RHSC) subscales" of the French Intuitive Eating Scale-2 (IES-2) questionnaire at the first GDM clinic visit were included in this study.

RESULTS

Participants' mean age was 33.32 ± 5.20 years. Their weight and BMI before pregnancy were 68.18 ± 14.83 kg and 25.30 ± 5.19 kg/m² respectively. After adjusting for confounding variables, the cross-sectional analyses showed that the two subscales of IES-2 at the first GDM visit were associated with lower weight and BMI before pregnancy, and lower weight at the first GDM visit (β = -0.181 to -0.215, all p ≤ 0.008). In addition, the EPR subscale was associated with HbA1c and fasting plasma glucose at the first GDM visit (β = -0.170 and to -0.196; all p ≤ 0.016). In the longitudinal analyses, both subscales of IES-2 at first GDM visit were associated with lower weight at the end of pregnancy, BMI and fasting plasma glucose at 6-8 weeks postpartum (β = -0.143 to -0.218, all p ≤ 0.040) after adjusting for confounders.

CONCLUSIONS

Increase adherence to IE could represent a novel approach to weight and glucose control during and after pregnancy in women with GDM.

Real-time predictors and consequences of binge eating among adults with type 1 diabetes

BACKGROUND

Objective binge eating (OBE) is common among individuals with type 1 diabetes (T1D) and may have negative consequences for glycemic control. Recent studies have suggested that diabetes distress (i.e., emotional distress specific to diabetes and living with the burden of management) is a distinct emotional experience among individuals with diabetes. Preliminary studies have found diabetes distress is associated with eating disorder symptoms and poor glycemic control. The aim of the current study was to examine real-time emotional precursors and consequences of OBE in adults with T1D (i.e., general negative affect, specific emotional states and diabetes distress) using ecological momentary assessment methods. We also explore the impact of OBE on 2-h postprandial glycemic control relative to non-OBE eating episodes.

METHODS

Adults with T1D (N = 83) completed 3-days of ecological momentary assessment assessing mood and eating behavior using a telephone-based survey system. Participants were prompted to rate momentary affect, including level diabetes distress, at random intervals and reported on eating episodes. Participants also wore continuous glucose monitors allowing for ongoing assessment of glycemic control. Multi-level modeling was used to examine between- and within-person effects of momentary increases in emotions prior to eating on the likelihood of OBE and the impact of OBE on postprandial blood glucose. Generalized linear mixed models examined whether change in post-meal affect differed between OBE and non-OBE episodes.

RESULTS

Participants were predominately middle-aged (Mean = 42; SD = 12.43) Caucasian (87%) females (88%) reporting clinically significant eating disorder symptoms (76%). Nearly half of the sample (43%) reported OBE during the 3-day study period. The between-person effect for negative affect was significant (OR = 1.93, p < .05), indicating a 93% increased risk of OBE among individuals with higher negative affect compared to individuals with average negative affect. Between-person effects were also significant for guilt, frustration and diabetes distress (OR = 1.48-1.77, ps < .05). Analyses indicated that mean change in post-meal negative affect was significantly greater for OBE relative to non-OBE episodes (B = 0.44, p < .001). Blood glucose at 120 min postprandial was also higher for OBE than for non-OBE episodes (p = .03).

CONCLUSIONS

Findings indicate that individuals who tend to experience negative affect and diabetes distress before eating are at increased risk of OBE at the upcoming meal. Results also suggest that engaging in binge eating may result in greater subsequent negative affect, including diabetes distress, and lead to elevated postprandial blood glucose levels. These findings add to a growing literature suggesting diabetes distress is related to eating disordered behaviors among individuals with T1D.

Increased prevalence of disordered eating in the dual diagnosis of type 1 diabetes mellitus and celiac disease

BACKGROUND

Disordered eating behaviors (DEBs) may lead to full blown eating disorders. Both type 1 diabetes mellitus (T1DM) and celiac disease (CD) have been linked to DEBs.

OBJECTIVE

To compare the presence of DEBs between adolescents and young adults with a dual diagnosis of T1DM and CD, and individuals with only one of the diagnoses.

METHODS

Individuals with a dual diagnosis of T1DM and CD ("T1DM + CD group" n = 39), with a diagnosis of T1DM only ("T1DM group" n = 97) and with a diagnosis of CD only ("CD group" n = 267) filled the Eating Attitude Test-26 (EAT-26) questionnaire. Those with T1DM completed in addition to the Diabetes Eating Problem Survey-Revised (DEPS-R).

RESULTS

The study population comprised of 403 individuals, of whom 65% were females. There were no statistically significant differences among the groups in distribution of sex, age, hemoglobin A1c (HbA1c) levels, age of disease diagnosis and duration. The prevalence of DEBs in the T1DM + CD group was 3-fold higher (26.0%) than in the T1DM (8.2%) and CD (8.2%) groups (P = .003). This trend was observed for both females and males. Multivariate analysis demonstrated that the T1DM + CD group had an increased risk for DEBs (odds ratio, OR: 4.7, 95% confidence interval, CI: 1.9-11.2, P = .001) after adjustment for age, sex, and body mass index. Additionally, being female, older and overweight increased the risk for DEBs. HbA1c values were not associated with an increased DEBs rate.

CONCLUSIONS

Individuals with the dual diagnoses of T1DM and CD have an increased likelihood to develop DEBs compared to those with only one of these diagnoses.

Systematic review and meta-analysis of the efficacy of interventions for people with Type 1 diabetes mellitus and disordered eating

AIM

To examine the types of interventions currently available for people with Type 1 diabetes mellitus and their effectiveness.

BACKGROUND

The prevalence of disordered eating in people with Type 1 diabetes mellitus is twice that in their counterparts without diabetes, and is associated with worse biomedical outcomes and greater mortality.

METHODS

Medline, Embase, PsycINFO, the Cochrane Library, PubMed and OpenGrey databases were searched up to August 2016 to identify studies on interventions in people with Type 1 diabetes-associated disordered eating. For the systematic review, intervention components were identified and their effectiveness was examined. For the meta-analysis, the pooled effect sizes of glycaemic control (HbA_1c ) between pre- and post-treatment in treatment and comparison groups were calculated using a random effects model.

RESULTS

Of 91 abstracts reviewed, six studies met the inclusion criteria, of which three had appropriate data for the meta-analysis (n = 118). The pooled effect size was -0.21 95% CI (-0.58 to 0.16; where negative values represent an improvement in HbA_1c levels), indicating no statistically significant improvement in the treatment group compared with comparison group. Inpatient therapy appeared to be the most effective treatment, and this had multiple components including cognitive behavioural therapy, psychoeducation and family therapy.

CONCLUSION

Limited or no improvement in glycaemic control and disordered eating symptoms was observed in people with Type 1 diabetes-associated disordered eating who were receiving currently available interventions. The present review suggests that developing an intensive intervention with a joint focus on both disordered eating and diabetes management is needed for this complex patient group.

Appearance Investment, Quality of Life, and Metabolic Control Among Women with Type 1 Diabetes

BACKGROUND

Concomitants of Type 1 diabetes management include weight gain and dietary restraint. Body image concerns, particularly among women, are therefore common.

PURPOSE

The study evaluated associations between the appearance investment component of body image, age, quality of life and self-reported metabolic control were examined, along with the practice of insulin restriction as a weight control strategy.

METHOD

A questionnaire comprising demographic and diabetes-related information, the Appearance Schemas Inventory, and Diabetes Quality of Life Brief Clinical Inventory was completed by Australian women diagnosed with type 1 diabetes (N = 177).

RESULTS

Self-evaluative salience was higher among younger participants, those with a lower quality of life, and those with better metabolic control of their diabetes, with the relationships between metabolic control and all of age, quality of life, and self-evaluative salience noted to be non-linear. Among participants who reported restricting insulin for weight control, self-evaluative salience was particularly relevant. Motivational salience was not related to other study variables.

CONCLUSION

Clinically, the provision of information regarding appearance changes that might arise in order to mitigate later body image difficulties is a potentially beneficial adjunct to standard diabetes management protocols that may lead to more successful disease adjustment.

Translation and validation of the Diabetes Eating Problem Survey to screen eating disorders in patients with type-1 diabetes mellitus

INTRODUCTION

The treatment of type-1 diabetes mellitus (T1DM) requires changes in patients' eating habits and lifestyles which could lead to the development of an eating disorder (ED). An early detection of these disorders in subjects with T1DM is necessary. However, there is no specific questionnaire concerning the presence of an ED in these patients.

OBJECTIVES

To translate and validate for the Spanish population a specific questionnaire aimed at detecting the risk of onset of an ED on a sample of subjects with T1DM. To analyze its agreement with its shortened version and with the gold standard tool, EAT-26.

MATERIAL AND METHODS

Cross-sectional study. The study population consisted of 112 adults with T1DM. The EAT-26 tool and DEPS-R questionnaire were used to detect subjects at risk for developing ED. In addition, several characteristics such as weight, height, BMI, age and age of onset were assessed by means of self-administered questionnaires, in order to study their correlation with test scoring.

RESULTS

Structural properties of the tests were evaluated through methodological procedures aimed at calculating reliability and validity. The translated and adapted version had a high consistency in both its complete and summarized version (α=0,821).The test-retest also yielded consistent results (intraclass correlation coefficient 95.8% for EPAD and 92.3% for EPAD-R). The factor analysis yielded 5 factors: 1) Eating attitudes; 2) Bulimic behavior; 3) Weight control; 4) Avoidance, and 5) Restriction.

CONCLUSIONS

We have developed a questionnaire in Spanish capable of identifying the risk of onset of a specific ED in patients with T1DM. The EPAD-R questionnaire detected 10% more cases and different ones than those detected by the EAT-26 test. It is necessary to use specific screening tools to correctly identify eating disorders in patients with T1DM.

Psychological conditions in adults with diabetes

Type 1 (T1D) and Type 2 diabetes (T2D) represent a demanding set of biopsychosocial challenges for patients and their families, whether the age of disease onset occurs in childhood, adolescence, or adulthood. Psychological conditions, defined as syndromes, disorders, and diabetes-specific psychological issues affect a larger proportion of individuals with T1D and T2D compared to the general population. In this review, we summarize the prevalence, impact and psychological treatments associated with the primary categories of psychological conditions that affect adults with T1D and T2D: depressive symptoms and syndromes, anxiety disorders, eating behaviors and disorders and serious mental illness. The implications of the literature for psychologists are discussed, and priorities for future research to advance the science of psychological conditions for adults with T1D and T2D are identified.

Testing an integrated model of eating disorders in paediatric type 1 diabetes mellitus

BACKGROUND

Eating disorders in young people with type 1 diabetes mellitus confer additional health risks beyond those conferred by the disease itself. Risk factors for developing eating disorders are poorly understood.

OBJECTIVE

The current study aimed to examine risk factors for eating disturbance in young people with type 1 diabetes mellitus. Both diabetes specific risk factors, such as body mass index (BMI), glycaemic control and diabetes-related conflict, and also more general risk factors such as dysfunctional perfectionism and low self-esteem were assessed.

METHODS

Fifty young people aged 14-16 and their primary caregiver were asked to complete interviews and questionnaires about their eating attitudes and behaviours, dysfunctional perfectionism, self-esteem, family conflict, and general mental health symptoms. Recent weight and height and glycaemic control were extracted from the medical file.

RESULTS

Different factors distinguished those young people who displayed eating disorder attitudes from those who did not (higher BMI-z, poorer glycaemic control, and lower self-esteem) and those young people who displayed eating disorder behaviour from those who did not (lower self-esteem and higher diabetes-related family conflict).

CONCLUSIONS

The results of the current study suggest that there might be different factors associated with eating disorders (ED) attitudes and ED behaviours, but that food/eating-related factors, family factors, and intra-personal factors are all important. Furthermore there are some gender differences in the presence of ED attitudes and behaviours and preliminary evidence that higher body mass indexes (BMIs) impact on girls more than they do on boys.

Intuitive eating is associated with glycaemic control in adolescents with type I diabetes mellitus

BACKGROUND

While there have been considerable advances in the medical management of type 1 diabetes mellitus (T1DM), for many, glycaemic control remains substandard. Nutrition and eating behaviour are important additional factors to consider with regards to T1DM management and outcomes. Intuitive eating is one such factor, and has not previously been investigated in T1DM. With this in mind, we undertook a study examining the relationship between intuitive eating and glycaemic control in adolescents with T1DM.

METHODS

A case-control study of adolescents with established T1DM, and age/sex matched controls was conducted. Demographic information, the Intuitive Eating Scale (IES), and HbA1c were collected. Statistical analysis was undertaken to explore associations between the IES and HbA1c as a marker of glycaemic control.

RESULTS

Data on 38 adolescents with T1DM, and 39 age/sex matched controls were obtained. Those with T1DM had significantly lower (by 0.5 SD) IES scores compared to controls (p = 0.009). Higher values of both total IES and the Eating for physical rather than emotional reasons subscale were associated with lower HbA1c: HbA1c 22% lower/whole unit increase in total IES mean score, HbA1c 11% lower/whole unit increase in Eating for physical rather than emotional reasons mean score, p = 0.017 and p = 0.009 respectively.

CONCLUSION

In adolescents with T1DM, there appears to be a strong association between intuitive eating, in particular the effect of emotion on eating, and glycaemic control. In addition, those with T1DM have lower scores for their intuitive eating behaviour compared to controls. Emotional eating could be a future target for screening and potentially intervening in those with T1DM, as part of a wider treatment package to improve glycaemic control. Continuing efforts are needed to fully understand the important dynamics of diabetes, adolescence, diet, emotion, and how these factors affect long term outcomes in those with T1DM.

Relationship of sexual dysfunction and its associated factors in women with genital and breast cancers

Background:

Sexuality is a basic and important factor in human experiences, which varies among different types of cancers. This study was carried out with the aim of defining the relationship between sexual dysfunction and related factors in genital and breast cancers.

Materials and Methods:

This cross-sectional study was conducted on 150 women with genital and breast cancers admitted to two specialized hospitals in Isfahan and by using a two-stage sampling method. Participants completed demographic/disease questionnaire and sexual function questionnaire. Collected data were analyzed by using SPSS software version 14 and statistical tests of correlation coefficient, Student's t-test and one-way analysis of variance (ANOVA).

Results:

The obtained results showed that 47% of women had sexual dysfunction with the mean (SD) age of 47 (7.7) years (with the range of 25–65 years). There was a significant correlation between sexual functioning and age, occupation, educational level, and treatment duration (P < 0.05). There was also a significant correlation between the stage of disease, primary disorder (0.003), and recent disorder (0.028). Meanwhile, Chi-square test showed no significant relationship between cancer type and primary disorder (0.403) and recent disorder (0.416).

Conclusions:

Breast and genital cancers may result in significant difficulties with sexual functioning and sexual life. Addressing these problems is essential to improve the quality of life in women with cancer and further investigations should be conducted for prevention and treatment of disorders by the health authorities.

Diabetes IN develOpment (DINO): the bio-psychosocial, family functioning and parental well-being of youth with type 1 diabetes: a longitudinal cohort study design

Background

Strict glycemic control during adolescence decreases the risk of developing complications later in life, even if this level of control is not maintained afterwards. However, the majority of adolescents with type 1 diabetes (T1D) are in poor control and so far medical or psychological interventions have shown limited success. Adolescence is characterized by major biological, psychosocial, cognitive and parent–child relationship changes and the complex interaction between these developmental trajectories, and its impact on health outcomes is still poorly understood. A specific topic of interest in this context is the timing of diagnosis. The longitudinal study DINO (Diabetes IN develOpment) aims to examine:

If and how the onset of T1D before vs. during puberty results in different outcomes of glycemic control, self-management, psychological functioning and diabetes-related quality of life.

The timing of onset of disturbed eating behavior, its risk factors and its prospective course in relation to glycemic and psychological consequences.

If and how the onset of T1D before vs. during puberty results in different family functioning and parental well-being.

If and how the cognitive development of youth with T1D relates to glycemic control and diabetes self-management.

Methods/design

DINO, a longitudinal multi-center cohort study is conducted in youth with T1D in the age range 8–15 years at baseline. Participants will be divided into two subgroups: pre-pubertal and pubertal. Both groups will be followed for 3 years with assessments based on a bio-psychosocial model of diabetes, scheduled at baseline, 12 months, 24 months and 36 months examining the biological, psychosocial -including disturbed eating behaviors- and cognitive development, family functioning and parental well-being.

Discussion

A better understanding of how the different trajectories affect one another will help to gain insight in the protective and risk factors for glycemic outcomes and in who needs which support at what moment in time. First results are expected in 2016.

Weight control behaviors among emerging adults with type 1 diabetes

PURPOSE

The purpose of this study was to examine the association of weight control behaviors (WCBs) with living and educational situations among emerging adults with type 1 diabetes during the first year after high school graduation.

METHODS

Among 184 emerging adults with type 1 diabetes, data were collected every 3 months for 12 months on WCBs, body mass index (BMI), living and educational situations; at baseline and 12 months, on impulse control; and at baseline, on sex, depressive symptoms, and glycemic control. Generalized linear models incorporated repeated measures (0, 3, 6, 9, and 12 months).

RESULTS

No significant associations existed between WCBs and living or educational situations, when controlling for covariates. More depressive symptoms and higher BMIs were associated with a greater likelihood of involvement in unhealthy WCBs, whereas more depressive symptoms-not higher BMI-were associated with higher odds for involvement in very unhealthy WCBs. Although healthy WCBs were also associated with more depressive symptoms and higher BMIs, they were also associated with greater impulse control.

CONCLUSIONS

Health care professionals should assess emerging adults with type 1 diabetes for WCBs along with BMI, depressive symptoms, and impulse control.

The neurobiology of eating disorders--a clinical perspective

OBJECTIVE

To provide a neurobiological basis of eating disorders for clinicians and to enlighten how comparing neurobiology and eating disorders with neurobiology of other psychiatric illnesses can improve treatment protocols.

METHOD

A selective review on the neurobiology of eating disorders. The article focuses on clinical research on humans with consideration of the anatomical, neural, and molecular basis of eating disorders.

RESULTS

The neurobiology of people with eating disorders is altered. Many of the neurobiological regions, receptors, and chemical substrates that are affected in other mental illnesses also play an important role in eating disorders. More knowledge about the neurobiological overlap between eating disorders and other psychiatric populations will help when developing treatment protocols not the least regarding that comorbidity is common in patients with EDs.

CONCLUSION

Knowledge about the underlying neurobiology of eating disorders will improve treatment intervention and will benefit from comparisons with other mental illnesses and their treatments.

Multidisciplinary residential treatment of type 1 diabetes mellitus and co-occurring eating disorders

Research on treatment for diabetes and co-occurring eating disorders is sparse. We examined outcomes from multidisciplinary residential treatment for women with type 1 diabetes and eating disorders and the impact of treatment duration on outcomes. Participants were 29 women with type 1 diabetes and eating disorders receiving residential treatment. Repeated measures analyses of variance examined changes in blood glucose and psychological symptoms over treatment. Analyses were repeated to include treatment by duration interactions. Treatment produced significant reductions in blood glucose, eating disorder symptoms, and psychological concerns. Longer treatment duration was associated with greater improvements in psychological symptoms.

Double jeopardy. Addressing diabetes and eating disorders among adolescents in the school setting

Eating disorders are more common in youth with diabetes, especially females, and not only interfere with diabetes management but can increase the risk for diabetes-related complications. School nurses may be the first to recognize eating disorders among students with diabetes. They are an integral part of a multidisciplinary team, connecting students and families to both health care and community resources, ensuring that mental, physical, and social needs are addressed.

Disinhibited eating and weight-related insulin mismanagement among individuals with type 1 diabetes

OBJECTIVE

Withholding insulin for weight control is a dangerous practice among individuals with type 1 diabetes; yet little is known about the factors associated with this behavior. Studies of nondiabetic individuals with weight concerns suggest that eating in a disinhibited manner (e.g., binge eating) predicts the use of maladaptive compensatory strategies (e.g., self-induced vomiting). The purpose of this study was to test whether individuals with type 1 diabetes are less restrained in their eating when they think their blood glucose (BG) is low and whether this contributes to insulin omission for weight control purposes and subsequently higher hemoglobin A1c (HbA1c).

METHODS

Two-hundred and seventy-six individuals with type 1 diabetes completed an online survey of eating behaviors, insulin dosing and most recent HbA1c. We used structural equation modeling to test the hypothesis that disinhibited eating when blood sugar is thought to be low predicts weight-related insulin mismanagement, and this, in turn, predicts higher HbA1c.

RESULTS

The majority of participants endorsed some degree of disinhibition when they think their blood glucose is low (e.g., eating foods they do not typically allow) and corresponding negative affect (e.g., guilt/shame). The frequency of disinhibited eating was positively associated with weight-related insulin mismanagement. Controlling for age, sex, education, and insulin pump use, the model explained 31.3% of the variance in weight-related insulin mismanagement and 16.8% of the variance in HbA1c.

CONCLUSION

Addressing antecedents to disinhibited eating that are unique to type 1 diabetes (e.g., perceived BG level) and associated guilt or shame may reduce weight-related insulin omission.

Is disordered eating behavior more prevalent in adolescents with early-onset type 1 diabetes than in their representative peers?

OBJECTIVE

Despite modern therapeutic regimens, youths with Type 1 diabetes may be at increased risk of mental and behavioral disorders. In this study, the prevalence of disordered eating behavior (DEB) in intensely treated children and adolescents with early-onset Type 1 diabetes and peers from the general population was compared.

METHOD

Data from 629 patients from a population-based, nationwide survey (54.1% male, mean age 15.3 years) with early-onset Type 1 diabetes of at least 10 years duration were compared with data from 6,813 participants of the German KiGGS study (51.3% male, mean age 14.6 years). The generic SCOFF questionnaire was used as screening instrument to identify participants with symptoms of DEB. Both groups were compared with multivariable regression analysis adjusting for sociodemographic covariates.

RESULTS

31.2% of the female and 11.7% of the male diabetic patients and 28.9% of the females and 15.2% of the males in the comparison group were SCOFF-positive (SCOFF score ≥2; p > .05). The odds for symptoms of eating disorders were 3.7% higher in female and 4.3% lower in male patients with diabetes than in the comparison group, but the differences were not significant. 20.5% of the female and 18.5% of the male diabetic patients reported insulin restriction at least three times per week.

DISCUSSION

Children and adolescents with early-onset Type 1 diabetes of long duration do not seem to be more frequently SCOFF-positive than peers. However, as insulin restriction is practiced in a substantial portion of patients, attention for insulin restriction in diabetes care is essential.

The evaluation of body image in children with type 1 diabetes: A case-control study

This study evaluated the body image perception in children with type 1 diabetes in order to identify symptoms of disordered eating behaviours early. Children with type 1 diabetes and controls showed underestimation and dissatisfaction with body size. The patients, especially girls, were more accurate in their perception of body size than the control group. The study sheds light on some of the underlying factors that may contribute to the development of disordered eating behaviours in adolescence. The causes of the differences of perception of body size are discussed.

Primary care of female adolescents with type 1 diabetes mellitus and disordered eating

AIM

To identify the role of the nurse practitioner in caring for female adolescents with type 1 diabetes mellitus at risk for disordered eating behaviour and to formulate clinical recommendations for nurse practitioners in the primary care setting.

BACKGROUND

Transition into adulthood can be difficult for female adolescents with type 1 diabetes mellitus. Challenges associated with management of this illness may place adolescent females at an increased risk for disordered eating.

DESIGN

Discussion paper.

DATA SOURCES

Sourced literature from 1991-2013, located through CINAHL, Health Source, Proquest, PubMed, PsychInfo, Web of Science and Medline databases.

IMPLICATIONS FOR NURSING

Nurses involved in the primary care of female adolescents with type 1 diabetes mellitus need to be aware of the increased risk for disordered eating behaviours and develop the competencies to care for both the adolescent and her family to reduce the serious consequences of these behaviours.

CONCLUSION

Awareness and acquisition of the skills required to intervene will enable nurse practitioners to recognize clients at risk for disordered eating, gain appreciation of the motivation of female adolescents with type 1 diabetes mellitus towards disordered eating behaviours and give optimal opportunity for education, counselling and recovery. Future direction for research includes exploration of the experiences of adolescents with type 1 diabetes mellitus; early interventions in the primary care setting; effective educational, preventative or supportive services for adolescents with this illness and their families; and outcomes to emerging technologies for insulin therapy on disordered eating occurrence.

Eating Disorders and Disordered Eating in Type 1 Diabetes: Prevalence, Screening, and Treatment Options

This review is focused on the prevalence of eating disorders and disordered eating behaviors in individuals with type 1 diabetes. Recent research indicates higher prevalence rates of eating disorders among people with type 1 diabetes compared with their peers without diabetes. Eating disorders and disordered eating behaviors-especially insulin omission-are associated with poorer glycemic control and serious risk for increased morbidity and mortality. Screening should begin in pre-adolescence and continue through early adulthood, as many disordered eating behaviors begin during the transition to adolescence and may persist for years. Available screening tools and treatment options are reviewed. Given the complexity of diabetes management in combination with eating disorder treatment, it is imperative to screen early and often, in order to identify those most vulnerable and begin appropriate treatment in a timely manner.

Long-term consequences of anorexia nervosa

Anorexia nervosa (AN) is a psychiatric disorder that occurs mainly in female adolescents and young women. The obsessive fear of weight gain, critically limited food intake and neuroendocrine aberrations characteristic of AN have both short- and long-term consequences for the reproductive, cardiovascular, gastrointestinal and skeletal systems. Neuroendocrine changes include impairment of gonadotropin releasing-hormone (GnRH) pulsatile secretion and changes in neuropeptide activity at the hypothalamic level, which cause profound hypoestrogenism. AN is related to a decrease in bone mass density, which can lead to osteopenia and osteoporosis and a significant increase in fracture risk in later life. Rates of birth complications and low birth weight may be higher in women with previous AN. The condition is associated with fertility problems, unplanned pregnancies and generally negative attitudes to pregnancy. During pregnancy, women with the condition have higher rates of hyperemesis gravidarum, anaemia and obstetric complications, as well as impaired weight gain and compromised intrauterine foetal growth. It is reported that 80% of AN patients are affected by a cardiac complications such as sinus bradycardia, a prolonged QT interval on electrocardiography, arrythmias, myocardial mass modification and hypotension. A decrease in bone mineral density (BMD) is one of the most important medical consequences of AN. Reduced BMD may subsequently lead to a three- to seven-fold increased risk of spontaneous fractures. Untreated AN is associated with a significant increase in the risk of death. Better detection and sophisticated therapy should prevent the long-term consequences of this disorder. The aims of treatment are not only recovery but also prophylaxis and relief of the long-term effects of this disorder. Further investigations of the long-term disease risk are needed.

Chronic illness and disordered eating: a discussion of the literature

This paper describes the prevalence of eating disorders and disordered eating behaviors, the reasons why these practices are endorsed, and the potential consequences in youths and young adults with selected diet-related chronic health conditions (DRCHCs) and provides recommendations for eating disorder prevention interventions and research efforts. Although it remains unclear whether the prevalence of eating disorders is higher in those with DRCHCs compared with the general population, overall findings suggest that young people with DRCHCs may be at risk of endorsing disordered eating behaviors that may lead to diagnosis of an eating disorder and other health problems over the course of their treatment. Thus, health care providers should be aware that young people with DRCHCs may be at risk of eating disorders and carefully monitor psychological changes and the use of unhealthy weight control methods. It is also important to develop and evaluate theory-based interventions and disease-specific eating disorder risk screening tools that are effective in halting the progression of eating disorders and negative health outcomes in young people with chronic health conditions.

Eating disorders in adolescents with type 2 and type 1 diabetes

Diabetes is associated with increased risk for eating disorders; with different types of eating disorders associating with different types of diabetes. Binge eating disorders show increased prevalence among individuals with type 2 diabetes (T2DM). Intentional omission of insulin for the purpose of inducing weight loss presents among individuals with type 1 (T1DM). Similarly, some individuals with T2DM intentionally omit oral hypoglycemic drugs, resulting in poor glycemic control, and weight loss. Common dominators for the development of eating disorders in T1DM and T2DM are female gender, increased body weight, body dissatisfaction, a history of dieting, and a history of depression. Patients tend to deny the existence of the problem. Clinical signs that should raise suspicion are: poor glycemic control, missed clinical appointments, recurrent episodes of diabetes ketoacidosis, recurrent hypoglycemia secondary to intentional overdose, poor self-esteem, and dietary manipulation. Eating disorders are associated with poorer glycemic control, and therefore increased risk of diabetes associated comorbidities.

Disturbed eating behaviours and thoughts in Australian adolescents with type 1 diabetes

AIM

To describe the presence and type of disturbed eating behaviours and thoughts in a combined male/female Australian sample of adolescents with type 1 diabetes, and examine the association of eating behaviours and thoughts with glycaemic control as evidenced by high glycosylated haemoglobin levels (HbA1c).

METHODS

In this cross-sectional descriptive study, 124 adolescents aged 13-18  years were invited to complete three self-administered questionnaires. The Youth Eating Disorder Examination Questionnaire (YEDE-Q) and the Eating Disorder Inventory -3 Risk Composite (EDI-3RC) assessed risk for an eating disorder. The third questionnaire, the Strengths and Difficulties Questionnaire (SDQ) assessed emotional and behavioural concerns. Clinical data were collected from the medical records, routine clinic appointments and the adolescent.

RESULTS

Any disturbed eating behaviour was reported by approximately one-third of participants (32.3%) and was common in females and males (37.9% vs. 25.9%). Binge eating (17.7%), driven exercise (13.0%) and dietary restraint (8.9%) were the most common disturbed eating behaviours, although restraint was not evident in males. Insulin manipulation/omission (5.6%), vomiting (3.3%), laxative (0.8%) or diuretic use (0.8%) were less common. Regression analysis showed a significant association between HbA1c and more disturbed eating behaviours and thoughts which remained significant when adjusted for confounders.

CONCLUSIONS

High rates of disturbed eating behaviours and thoughts were seen in this Australian sample of adolescents with type 1 diabetes. High scores on both eating disorder measures were associated with poorer glycaemic control. These results highlight the need to screen for disordered eating in adolescents with type 1 diabetes.

Disordered eating behaviors are associated with poorer diet quality in adolescents with type 1 diabetes

Disordered eating behaviors may pose a risk for poor long-term health outcomes in patients with type 1 diabetes. This cross-sectional study examined associations of disordered eating behaviors with diet quality, diet-related attitudes, and diabetes management in adolescents with type 1 diabetes (N=151, 48% female). Participants, recruited July 2008 through February 2009, completed 3-day diet records and survey measures, including the Diabetes Eating Problem Survey (DEPS) and measures of eating-related attitudes. Biomedical data were obtained from medical records. Participants scoring more than 1 standard deviation above the mean DEPS were classified as at risk for disordered eating. The Healthy Eating Index-2005 was calculated to assess diet quality. Analysis of covariance was used to test for differences between risk groups in diet quality, eating attitudes, and diabetes management, controlling for age, sex, and body mass index (BMI) percentile. Youth at risk for disordered eating were more likely to be overweight/obese than those at low risk (59.1% vs 31.8%, P=0.01). The at-risk group had poorer diet quality (P=0.003) as well as higher intake of total fat (P=0.01) and saturated fat (P=0.007) compared with the low-risk group. The at-risk group reported lower self-efficacy (P=0.005), greater barriers (P<0.001), and more negative outcome expectations (P<0.001) for healthful eating, as well as worse dietary satisfaction (P=0.004). The at-risk group had lower diabetes adherence (P<0.01), less-frequent blood glucose monitoring (P<0.002), and higher hemoglobin A1c (P<0.001). The constellation of excess weight, poorer dietary intake, and poorer diabetes management associated with youth at risk for disordered eating suggests potential risk of future poor health outcomes. Attention should be given to healthful weight management, especially among overweight youth with type 1 diabetes.

Case-control study of disturbed eating behaviors and related psychographic characteristics in young adults with and without diet-related chronic health conditions

Young adults with diet-related chronic health conditions (DRCHCs; i.e., type 1 diabetes, celiac disease, cystic fibrosis, inflammatory bowel diseases, irritable bowel syndrome) face challenges complying with dietary restrictions required to effectively manage their health condition. These restrictions could put them at risk for disturbed eating. The purpose of this study was to determine if young adults with and without DRCHCs differed with regard to disturbed eating behaviors and related psychographics characteristics (i.e., body image attributes, mental disorders, intrapersonal characteristics and sociocultural environment [i.e., media and family]). Each DRCHC participant (cases=166) was matched to 4 healthy participants (controls=664) based on gender and BMI (±0.50 BMI units). Conditional logistic regression analyses indicate cases were twice as likely to have been diagnosed by a healthcare provider with an eating disorder (p=0.08, OR=1.99, CI(90) [1.03-3.83]). Cases were significantly more likely to use Inappropriate Compensatory Behaviors to manage their weight, i.e., excessive exercise (p=0.04, OR=1.41, CI(95) [1.02-1.94]) and misuse medication (p=0.04, OR=1.14, CI(95) [1.00-1.29]) than controls. Depression and anxiety were significantly higher, and health status was significantly poorer in cases compared with controls. DRCHC participants were less likely to report feeling body image pressures from the media, placed a greater value on their health, used social diversion, and recalled a greater emphasis being placed on their mothers' weights and mealtimes being less structured than control participants. Findings indicate that nutrition and other healthcare professionals should incorporate screening DRCHC patients for disturbed eating behaviors and eating disorders in their standards of care.

Comorbid Diabetes and Eating Disorders in Adult Patients

Purpose

The lack of research concerning treatment for individuals with diabetes mellitus (DM) and comorbid eating disorders (ED) contributes to the gulf between the psychosocial needs of individuals with the two conditions and the treatment they receive. Empirical evidence has established that the prognosis of patients with this comorbid diagnosis (ED-DM) is poor in the absence of a specialized DM treatment specifically adapted to ED. In individuals with DM, comorbid ED is associated with numerous complications. Despite these interactions, current knowledge about the comorbid diagnosis is limited, and eating disorders in patients with diabetes often remain undiagnosed. This article presents standard procedures for assessment and optimal therapeutic interventions for patients with ED and DM.

Conclusion

In patients with diabetes, problematic eating behaviors and symptoms should be assessed routinely. When an eating disorder is detected, diabetes management needs to be adapted, binge eating or medication misuse needs to be addressed, and eating disorder specialists should be included in the multidisciplinary team.

Food perceptions and concerns of aboriginal women coping with gestational diabetes in Winnipeg, Manitoba

OBJECTIVE

To describe how Aboriginal women in an urban setting perceive dietary treatment recommendations associated with gestational diabetes mellitus (GDM).

DESIGN

Semi-structured explanatory model interviews explored Aboriginal women's illness experiences with GDM.

SETTING AND PARTICIPANTS

Twenty-nine self-declared Aboriginal women who had received a diagnosis of GDM within the last 5 years in Winnipeg, Manitoba.

MAIN OUTCOME MEASURES

Factors influencing Aboriginal women's prenatal food perceptions with GDM.

ANALYSIS

Thematic analysis was used through coding linkages and matrix queries to assist in identifying and categorizing patterns or relationships.

RESULTS

Participants associated fear, anxiety, and frustration with GDM. Emotional reactions appeared alongside negative relationships with food and other prescribed lifestyle treatments. Collectively, these results suggested that the experience of living with GDM can be overwhelming, as suggested by some of the complex factors influencing women's perceptions and reported behaviors. Discussions indicated many felt socially isolated and had a poor self-image and sense of failure resulting from ineffective GDM management practices.

CONCLUSIONS AND IMPLICATIONS

Future efforts should focus on self-efficacy and security in Aboriginal women's own interpretation of GDM, providing them with the understanding that there is potential for prevention and change.

The relationship between the age of onset of type 1 diabetes and the subsequent development of a severe eating disorder by female patients

OBJECTIVES

To determine the age of onset of type 1 diabetes that is most closely related to the subsequent development of a severe eating disorder such as anorexia nervosa (AN) or bulimia nervosa (BN).

METHODS

Participants were 53 female type 1 diabetes patients with AN or BN referred to our outpatient clinic from the Diabetes Center of Tokyo Women's Medical University. Forty-nine female type 1 diabetes patients who regularly visited the Diabetes Center and had no eating disorder-related problems constituted the 'direct control' group, whereas 941 female patients who for the first time visited the Diabetes Center constituted the 'historical control' group. The kernel function method was used to generate a density estimation of the onset age of each group and the chi-square test was used to compare the distribution.

RESULTS

The control groups had similar density shapes for the onset age of type 1 diabetes, but both differed from the 'eating disorder' group. For onset age 7-18 yr, the density of the 'eating disorder' group was higher than those of the control groups, but for the younger and older onset ages the densities were lower. The 'eating disorder' group developed type 1 diabetes significantly more frequently than the 'historical control' group between 7 and 18 yr of age (χ2 = 9.066, p < 0.011).

CONCLUSION

The development of type 1 diabetes in preadolescence or adolescence seems to place girls at risk for the subsequent development of AN or BN. Careful attention should be paid to these high-risk patients.
