Personal control and disordered eating in female adolescents with type 1 diabetes

Controlling the Diabetic Body? Managing Chronic Illness with Wearable Technology

I explore the experience of managing type 1 diabetes with wearable technology. Type 1 diabetes is a chronic illness which requires continuous maintenance to keep the blood glucose levels within range. Using autoethnography, I investigate both the practices of translating information from technology and from senses, and also from health authorities, into practices. I conclude that the management of type 1 diabetes is informed by an urge to control the body, but this situation can be understood otherwise from a logic of care.

Associations between Disordered Eating Behaviors and HbA1c in Young People with Type 1 Diabetes: A Systematic Review and Meta-analysis

BACKGROUND

In type 1 diabetes, disordered eating behaviors (DEB) can adversely impact HbA1c. Diabetes-adapted DEB questionnaires assess intentional insulin omission, whereas generic questionnaires do not. Given the number of studies describing DEB-HbA1c associations published over the past decade, an updated systematic review is warranted.

OBJECTIVE

The study aimed to examine the associations between DEBs assessed by generic and diabetes- adapted questionnaires (and subscales) and HbA1c among young people (<29 years) with type 1 diabetes.

METHODS

A systematic search was conducted in PubMed, Embase, PsycInfo, and CINAHL databases. Observational studies examining associations between DEB as assessed by questionnaires and HbA1c were included. Publication information, DEB and HbA1c characteristics, and DEBHbA1c associations were extracted. Hedges' g was calculated for mean HbA1c differences between groups with and without DEB.

RESULTS

The systematic search yielded 733 reports, of which 39 reports representing 35 unique studies met the inclusion criteria. Nineteen studies assessing DEB by diabetes-adapted questionnaires (n=5,795) and seven using generic questionnaires (n=2,162) provided data for meta-analysis. For diabetes-adapted questionnaires, DEB was associated with higher HbA1c (g=0.62 CI=0.52; 0.73) with a similar effect size when restricted to validated questionnaires (g=0.61; CI=0.50; 0.73). DEB was not associated with HbA1c for generic questionnaires (g=0.19; CI=-0.17; 0.55), but significantly associated with higher HbA1c for validated generic questionnaires (g=0.32; 95% CI=0.16-0.48). Participant and HbA1c collection characteristics were often inadequately described.

CONCLUSION

Diabetes-adapted DEB questionnaires should be used in youth with type 1 diabetes because they capture intentional insulin omission and are more strongly associated with HbA1c than generic DEB questionnaires.

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.

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.

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.

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.

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.

Eating problems in adolescents with Type 1 diabetes: a systematic review with meta-analysis

AIMS

We report a systematic review to determine (1) prevalence of eating problems compared with peers and (2) the association between eating problems and glycaemic control in young adults with Type 1 diabetes.

METHOD

  We conducted a systematic literature search via electronic databases and meta-analysis. Cohen's d (the mean difference score between Type 1 diabetes and comparison groups) was calculated for 13 studies that met inclusion criteria.

RESULTS

  Eating problems [both disordered eating behaviour (39.3 and 32.5%; d = 0.52, 95% CI 0.10-0.94) and eating disorders (7.0 and 2.8%; d = 0.46, 95% CI 0.10-0.81)] were more common in adolescents with Type 1 diabetes compared with peers and both were associated with poorer glycaemic control (d = 0.40, 95% CI 0.17-0.64). In restricted analyses involving measures adapted for diabetes, associations between eating problems and poorer glycaemic control remained (d = 0.54, 95% CI 0.32-0.76). Disordered eating behaviour (51.8 and 48.1%; d = 0.06, 95% CI -0.05 to 0.21) and eating disorders (6.4 and 3.0%; d = 0.43, 95% CI -0.06 to 0.91) were more common in adolescents with Type 1 diabetes compared with peers, but differences were non-significant.

CONCLUSIONS

  Eating problems are common among this age group. Future work in populations with Type 1 diabetes should develop sensitive measures of eating problems and interventions, and establish predictors of eating problems. Screening in clinics is recommended.

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.

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.

The role of free-play physical activity in healthy blood glucose maintenance in children with type 1 diabetes mellitus

Medical management for children with type 1 diabetes mellitus, including insulin administration to control high blood glucose levels (BGL), is crucial. However, a child-controlled behavioural strategy, like physical activity, to maintain target BGL may be warranted. To demonstrate, pre- and post-activity BGL were collected for 73 children aged 8- to 14-years attending a diabetes camp. Change in BGL across one session of a free-play swimming activity was analysed. Average BGL was significantly reduced from 197.18 mg/dl to 177.78 mg/dl across one 45 min session, and male gender predicted larger reductions. With safety precautions and within the context of appropriate medical management, free-play activity could be used as a strategy for maintaining target BGL.

Control and disordered eating in type 1 diabetes

Control is a major topic associated with the management of diabetes due to the importance placed on maintaining healthy blood glucose levels in this condition. Such an outcome can be influenced by individuals' sense of mastery over the disease, and more generally over their environment. In response to a diagnosis of diabetes, the self-management requirements accompanying it, and/or difficulties in other areas of life, patients may decide to undertake behaviours that are detrimental to their well-being. For instance, they may adopt fixated attitudes towards their intake and weight. This paper explores the relationship between disordered eating habits, control and diabetes in those who are insulin dependent.

Management strategies for brittle diabetes

Type 1 diabetes is an intrinsically unstable condition. However, the term "brittle diabetes" is reserved for those cases in which the instability, whatever its cause, results in disruption of life and often recurrent and/or prolonged hospitalization. It affects 3/1000 insulin-dependent diabetic patients, mainly young women. Its prognosis is poor with lower quality of life scores, more microvascular and pregnancy complications and shortened life expectancy. Three forms have been described: recurrent diabetic ketoacidosis, predominant hypoglycemic forms and mixed instability. Main causes of brittleness include malabsorption, certain drugs (alcohol, antipsychotics), defective insulin absorption or degradation, defect of hyperglycemic hormones especially glucocorticoid and glucagon, and above all delayed gastric emptying as a result of autonomic neuropathy. Psychosocial factors are very important and factitious brittleness may lead to a self-perpetuating condition. The assessment of brittle diabetes requires quantification of the variability of blood glucose levels. To quantify instability, measures which have been developed, include Mean Amplitude of the largest Glycemic Excursions (MAGE), Mean Of Daily Differences (MODD), Lability Index (LI), Low Blood Glucose Index (LBGI), Clarke's score, Hyposcore, and continuous blood glucose monitoring. Once psychogenic problems have been excluded, therapeutic strategies require firstly, the treatment of underlying organic causes of the brittleness whenever possible and secondly optimising standard insulin therapy using analogues, multiple injections and consideration of Continuous Subcutaneous Insulin Infusion. Alternative approaches may still be needed for the most severely affected patients. Isolated islet transplantation (IIT), which restores glucose sensing, should be considered in cases of hypoglycaemic unawareness and/or lability especially if the body mass index is < 25, but with current immunosuppressive protocols patients must have normal renal function and preferably no plans for pregnancy. Implantable pumps have advantages for patients who either weigh more than 80 kgs or have abnormalities of kidney or liver function or are highly sensitised.
