Risk behaviors for eating disorder in adolescents and adults with type 1 diabetes

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

AIMS

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

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.

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

BACKGROUND

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

AIM

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

METHODS

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

RESULTS

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

CONCLUSION

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

Higher score of diabetes eating problem survey-revised (DEPS-R) is associated with poor glycemic control among Brazilian patients with type 1 diabetes (T1DM): A brief report

BACKGROUND AND AIMS

The diabetes eating problem survey-revised (DEPS-R) questionnaire is a specific and valuable tool for assessing disturbed eating behavior in type 1 diabetes mellitus. The literature suggests an association between a higher DEPS-R score and worse metabolic control; however, these figures have not been described in patients from Latin America.

METHODS

We evaluated 58 patients with type 1 diabetes mellitus from a Brazilian outpatient clinic using the DEPS-R questionnaire.

RESULTS

Overall, 23 participants with a high risk for high eating disorder behaviors exhibited significantly increased hemoglobin A1c levels compared with 35 patients with a DEPS-R score <20.

CONCLUSIONS

Our data support that the presence of a DEPS-R score >20 negatively affects the metabolic control of patients with type 1 diabetes mellitus in Brazil.

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.

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

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

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.

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.

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.

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.

Disturbed eating behavior in pre-teen and teenage girls and boys with type 1 diabetes

AIM

To investigate Disturbed Eating Behavior (DEB) and eating patterns in the context of a teenage population with T1D.

METHODS

DEB was investigated using Eating Disorder Examination (EDE) test by a psychologist. Questions regarding insulin dosage manipulation or omission to obtain decrease in weight were added. Specific behavioral items from the EDE were used to define DEB: Objective Binge-eating, Self-induced Vomiting for weight control; the use of Diuretics, Laxatives or Insulin Omission for weight loss. Some EDE items provided information about four composite subscales which assesse Restraint, Eating concern, Shape concern and Weight concern.

RESULTS

Shape and Weight concern showed significantly higher scores than those observed in the other two subscales (p=0.021). Average scores of each subscale resulted significantly higher in girls than in boys as well as in teen than in pre-teen participants. Objective binge eating (20%) and insulin dosage omission or reduction (17.6%) were the most common DEB (p<0.03). Forty-one percent of participants reported to consume three, 25% four and 34% five meals daily. A significantly lower proportion of females than males resulted to consume breakfast and mid-afternoon snacks.

CONCLUSIONS

Findings from this study suggest that caregivers working in pediatric diabetes units should be alert in order to discover some DEB such as medication omission and binge-eating, all indicative symptoms of dissatisfaction of the body and psychological distress in diabetes management.

Are children with chronic illnesses requiring dietary therapy at risk for disordered eating or eating disorders? A systematic review

OBJECTIVE

Pediatric chronic illnesses (CI) can affect a child's mental health. Chronic illnesses with treatment regimens that specify a therapeutic diet may place the child at increased risk for disordered eating and specific eating disorders (ED). The aim of this review is to examine the relation between diet-treated CI and disordered eating and to determine the order of onset to infer directionality. Diet-treated CI is hypothesized to precede and to be associated with disordered eating.

METHOD

A comprehensive search of empirical articles that examine the relation between diet-treated CI (diabetes, cystic fibrosis, celiac disease, gastrointestinal disorders, and inflammatory bowel diseases) and disordered eating was conducted in Medline and PsycINFO using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A table of the sample's characteristics, ED measures, major pertinent findings, and the onset of CI in relation to ED were provided.

RESULTS

Diet-treated CI was associated with disordered eating and ED. Diet-treated CI had onset prior to disordered eating in most studies, except for inflammatory bowel diseases. Disordered eating and unhealthy weight management practices put children at risk for poor medical outcomes.

DISCUSSION

Interventions for diet-treated CI require a focus on diet and weight, but may increase the risk for disordered eating. Future research is needed to elucidate the mechanisms that transform standard treatment practices into pathological eating, including characteristics and behaviors of the child, parents/care providers, family, and treatment providers.

Diabetes, eating disorders and body image in young adults: an exploratory study about "diabulimia"

PURPOSE

The purpose of this study was to compare disordered eating (DE) and body image dissatisfaction (BID) among young adults with type 1 diabetes and their peers without diabetes, to investigate the consequences of diabetes for food, body image and weight in individuals with diabetes and to identify the behavior of insulin omission as a weight loss strategy.

METHODS

Fifty-five young adults with diabetes and 73 without diabetes (ages 18-30) completed self-report questionnaires to evaluate their behaviors, attitudes and feelings related to eating disorders and their perceptions about body image. The participants with diabetes were asked to answer a questionnaire with open and closed questions developed specifically for this study.

RESULTS

No significant differences between participants with and without diabetes in relation to BID and DE were found. The results demonstrated several changes resulting from diabetes in terms of food, body image and weight that interfere with the day-to-day life of individuals with diabetes; 7.3% of these participants reported insulin omission as a weight loss strategy.

CONCLUSIONS

This study emphasizes the importance of research on DE in the population with diabetes and their prevention, screening and treatment. In particular, it is essential to give more attention to insulin omission as a compensatory behavior that is inappropriate and harmful to health.

LEVEL OF EVIDENCE

Level III, case-control analytic study.

Interaction of Pubertal Development and Metabolic Control in Adolescents with Type 1 Diabetes Mellitus

BACKGROUND

In T1DM, delayed pubertal development and reduced final height are associated with inadequate metabolic control.

OBJECTIVE

To assess whether T1DM affects pubertal growth spurt and whether metabolic control during puberty is gender-related.

METHODS

Using a large multicentre database, longitudinal data from 1294 patients were analysed. Inclusion criteria: complete records of height and HbA1c from the age of seven to 16 years. Exclusion criteria: other significant chronic diseases and medications, T1DM duration less than three months, and initial BMI < 3rd or >97th percentile.

RESULTS

Growth velocity (GV) was impaired with a significant reduction of peak GV by 1.2 cm in boys. HbA1c increase during male puberty was lower except for a period of 1.5 years. The highest HbA1c increase in boys coincided with maximum growth spurt. In girls, the highest HbA1c increase was observed during late puberty. Even though there is impaired GV, both sexes reach a height at 16 years of age which corresponds to the background population height.

CONCLUSION

Worsening of metabolic control is sex-discordant and associated with gender-specific alterations of GV. However, the vast majority of boys and girls with T1DM seems to reach normal height at the age of 16 years.

Disturbed eating behavior in Iranian adolescent and young females with type-1 diabetes compared to non diabetic peers: A cross-sectional study

Background:

An association of eating disorder with diabetes mellitus may lead to a serious lack of metabolic control, higher mortality and morbidity. There is no recent study conducted in the Iranian population about eating disorder and its variants. The aim of the present study is investigation of frequency of disturbed eating behaviors in adolescent girls with type 1 diabetes mellitus (T1DM) compared to non-diabetics.

Materials and Methods:

In this cross-sectional study, disturbed eating behavior were evaluated and compared in two groups of 12–22 year old adolescent and young females (126 with diabetes and 325 without diabetes). A self-report questionnaire including demographic data, Children's Depression Inventory (CDI), and Eating Attitude Test (EAT-26) was used for data gathering. Independent t-test, Chi-square test, and logistic regression [odds ratio (OR)] were used for data analyses in SPSS 15.

Results:

Findings revealed that higher percentage of diabetic girls are likely to have eating disturbances (67.9% vs. 53.8%, P = 0.01). Diabetic group obtained higher scores in both dieting (14.95 ± 6.28 vs. 11.79 ± 5.62, P < 0.001) and bulimia scales (4.9 ± 3.13 vs. 4.12 ± 2.89, P = 0.017), which supports a role for T1DM in inducing the symptoms. Diabetic girls were at more than double the risk of developing eating disturbance.

Conclusions:

The results indicate that a significantly higher percentage of diabetic girls are likely to have eating disturbances. Also, diabetic subjects had an increased probability of getting higher scores in all three EAT-26 subscales. Therefore, healthcare professionals, especially diabetic nurses, should be aware of the potential effects of the subclinical and clinical eating behaviors on adolescents with T1DM and evaluate them for these disturbances.
