The psychological profile of youth and young adults with type 1 diabetes in New Zealand

Body mass index moderates the association between diabetes distress and objective self-management behaviours in adolescents with type 1 diabetes and elevated A1Cs

OBJECTIVE

To examine the cross-sectional associations between diabetes distress, BMI (zBMI; BMI z-score), objectively measured mean daily blood glucose readings and insulin boluses administered, and A1C in adolescents with type 1 diabetes (T1D) using insulin pumps.

METHODS

T1D self-management behaviour data were downloaded from adolescents' (N = 79) devices and mean daily frequency of blood glucose readings and insulin boluses were calculated. Diabetes distress was measured (Problem Areas in Diabetes-Teen questionnaire [PAID-T]), A1C collected, and zBMI calculated from height and weight. Three multiple linear regressions were performed with blood glucose readings, insulin boluses, and A1C as the three dependent variables and covariates (age, T1D duration), zBMI, diabetes distress, and the diabetes distress x zBMI interaction as independent variables.

RESULTS

Participants (55.7% female) were 14.9 ± 1.9 years old with T1D for 6.6 ± 3.4 years. zBMI moderated the relationship between diabetes distress and mean daily insulin boluses administered (b = -0.02, p = 0.02); those with higher zBMI and higher diabetes distress administered fewer daily insulin boluses. zBMI was not a moderator of the association between diabetes distress and blood glucose readings (b = -0.01, p = 0.29) or A1C (b = 0.002, p = 0.81).

CONCLUSIONS

Using objective behavioural data is useful for identifying how adolescent diabetes distress and zBMI affect daily bolusing behaviour amongst adolescent insulin pump users. Although distinct interventions exist to improve T1D self-management or diabetes distress, none addresses them together while considering zBMI. Decreasing diabetes distress could be especially important for youth with high zBMI.

Children and adolescents with type 1 diabetes in Aotearoa New Zealand: An online survey of workforce and outcomes 2021

AIMS

To survey the national workforce that manages children and adolescents with type 1 diabetes (T1D) in Aotearoa New Zealand and compare with glycaemic outcomes for 2021.

METHODS

A representative from each tertiary and regional diabetes service in Aotearoa New Zealand was asked to participate in an online survey assessing health-care professional (HCP) workforce numbers operating for the 2021 calendar year. Regional full-time-equivalent (FTE), glycaemic outcomes and population demographics were compared to a previously reported workforce surveys (2015 and 2019).

RESULTS

Seventeen sites responded - including all four large tertiary centres - serving >99% of children and adolescents with T1D in Aotearoa New Zealand. HCP resourcing varied across sites, with median (range) HCP/100 patient ratios of: doctors: 0.40 (0.16-1.11), nurses: 1.19 (0.29-5.56), dietitians: 0.25 (0-1.11) and psychologist/social workers: 0 (0-0.26). No site met all of the International Society of Paediatric and Adolescent Diabetes (ISPAD) recommendations of HCP/100 patient ratios. Measures of socio-economic deprivation predicted HbA1c, rather than the diabetes clinic attended. Overall, only 15.1% (240/1585) of patients had an HbA1c less than the recommended 53 mmol/mol.

CONCLUSIONS

The Aotearoa New Zealand workforce for children and adolescents with T1D is under-resourced and no site meets the ISPAD recommendations. There has been no significant increase in HCP/100 patient ratios compared to previous workforce surveys over the last decade. Few children and adolescents with T1D meet the recommended HbA1c. Resourcing according to recommended clinical need is required if equity in outcomes for young people with T1D is to be addressed.

Protocol for the STEADY intervention for type 1 diabetes and disordered eating: Safe management of people with Type 1 diabetes and EAting Disorders studY

This paper describes the protocol to test the feasibility of the Safe management of people with Type 1 diabetes and EAting Disorders studY (STEADY) intervention. STEADY is a novel complex intervention for people with type 1 diabetes and disordered eating (T1DE) of mild to moderate severity. The STEADY intervention integrates cognitive behavioural therapy (CBT) with diabetes education, and was developed using Experience-Based Co-Design. METHODS: The feasibility of STEADY will be tested using a randomised controlled feasibility trial. Forty adults with T1DE will be recruited and randomised into the STEADY intervention or treatment as usual control group. We will collect demographic, biomedical and psychometric data, routine glucose metrics and conduct the Structured Clinical Interview for DSM-5. Participants randomised to the STEADY intervention will receive 12 STEADY therapy sessions with a diabetes specialist nurse trained in CBT, delivered via videoconference and an optional smartphone app. The main outcome at 6 months will be the feasibility of STEADY (recruitment, dropout rates, feasibility of delivery). The secondary outcomes are biomedical (HbA1c and glucose time in range) and psychological (person-reported outcome measures in disordered eating, diabetes distress, depression and anxiety). A process evaluation will evaluate the fidelity, feasibility, acceptability and appropriateness of STEADY, and participant experiences. ETHICS AND DISSEMINATION: The protocol was approved by the East of England-Essex Research Ethics Committee (21/EE/0235). Study findings will be shared with study participants and disseminated through peer-reviewed publications and conference presentations.

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.

Epidemiology of Diabetic Ketoacidosis in the Waikato Region of New Zealand: 2000-2019

Aims

Diabetic ketoacidosis (DKA) is not well characterised in New Zealand. This study is aimed at characterising the change in epidemiology and severity of DKA from 2000 to 2019 at a tertiary hospital in the Waikato region of New Zealand.

Methods

A retrospective clinical data review of all patients admitted to Waikato District Health Board hospitals with DKA was undertaken. Characteristics and severity of DKA were assessed by type of DKA admission (diagnosed at admission, nonrecurrent, and recurrent), ethnicity, social deprivation, intensive care unit (ICU) admission, and length of hospital stay, with linear regression reporting on changes over time.

Results

There were 1254 admissions for DKA (564 individual patients), two-thirds being recurrent events. Nonrecurrent DKA patients were younger, whilst recurrent admissions for DKA were associated with T1D, female gender, greater socioeconomic deprivation, and rural living (all P values < 0.01). DKA admission increased 8-fold between 2000 and 2019, mostly due to an increased number of recurrent events, particularly in Māori and female patients (P < 0.001). ICU admissions increased over time (P < 0.001) whilst length of hospital stay trended down (P = 0.031).

Conclusions

The rise in recurrent DKA is concerning, particularly in youth and indigenous Māori. Healthcare inequities need to be addressed, including adequate access to mental health support to ensure optimal outcomes for all patients with diabetes.

Diabetes distress and disordered eating behaviors in youth with type 1 diabetes: the mediating role of self-regulatory fatigue and the moderating role of resilience

BACKGROUND

Despite previous research on the association between diabetes distress and disordered eating behaviors (DEBs) among youth with type 1 diabetes (T1D), there is a lack of understanding regarding the underlying mechanisms. This study aimed to investigate the relationships between diabetes distress and DEBs, specifically examining whether self-regulatory fatigue mediated the relationship and whether resilience moderated this mediation.

METHODS

A cross-sectional study was performed among youth with T1D recruited from two diabetes centers in Nanjing, China. Measurement instruments included the problem areas in the diabetes-5 scale, the diabetes strengths and resilience measure for adolescents, the self-regulatory fatigue scale, and the Chinese version of diabetes eating problem survey-revised. Mediation and moderated mediation analyses were conducted.

RESULTS

A total of 185 youths with T1D were involved in the current study. The results indicated that diabetes distress positively predicted DEBs. Self-regulatory fatigue partially mediated the association between diabetes distress and DEBs, accounting for 50.88% of the overall effect. Additionally, the pathway from self-regulatory fatigue to DEBs was moderated by resilience.

CONCLUSION

The current study examined whether self-regulatory fatigue mediated the relationship between diabetes distress and DEBs and whether resilience moderated the connection between self-regulatory fatigue and DEBs. These findings add to the theoretical basis of how diabetes distress influences DEBs and help guide the incorporation of diabetes distress, self-regulatory fatigue, and resilience into DEBs reduction programs for youth with T1D.

Screening for depression as part of annual diabetic review using PHQ-9 scores: a pilot study

Diabetes mellitus is associated with an increased risk of depression. Appropriate screening and treatment of depression may therefore support diabetes management in primary care. Study aim was to review the efficacy of using a Patient Health Questionnaire - (PHQ-9) tool to screen for depression in patients with type 2 diabetes mellitus (T2DM) in New Zealand.It was a cross-sectional study that included 100 consecutive patients with T2DM from two urban practices in Hamilton, New Zealand. Patients were screened using PHQ-9 scores.Using the PHQ-9, the overall prevalence of depression was 29% including 11 patients under active management/prescribing for depression and 18 undiagnosed patients. By ethnicity, depression affected 41.3%, 33.0%, 25.0% and 13.3% of NZ European, Māori, Pacific and other ethnicities, respectively. PHQ-9 scoring is an easy to administer tool that can be used to screen for unrecognized depression in patients with diabetes as a part of an annual diabetic review.

The WHO-5 well-being questionnaire in type 1 diabetes: screening for depression in pediatric and young adult subjects

OBJECTIVES

To evaluate the WHO-5 tool in pediatric and young adult subjects with type 1 diabetes, and to analyse associations with demographic/psychological characteristics.

METHODS

We included 944 patients with type 1 diabetes 9-25 years of age, documented in the Diabetes Patient Follow-up Registry between 2018 and 2021. We used ROC curve analysis to determine optimal cut-off values for the WHO-5 scores to predict psychiatric comorbidity (ICD-10-diagnoses) and analysed associations with obesity, HbA_1c, therapy regimen, and lifestyle via logistic regression. All models were adjusted for age, sex, and diabetes duration.

RESULTS

In the total cohort (54.8% male), the median score was 17 [Q1-Q3: 13-20]. Adjusted for age, sex, and diabetes duration, the WHO-5 scores<13 were associated with psychiatric comorbidity, especially depression and ADHD, poor metabolic control, obesity, smoking, and less physical activity. There were no significant associations with therapy regimen, hypertension, dyslipidemia, or social deprivation. In subjects with any diagnosed psychiatric disorder (prevalence 12.2%), the odds ratio for conspicuous scores was 3.28 [2.16-4.97] compared to patients without mental disorders. Using ROC analysis, the optimal cut-off to anticipate any psychiatric comorbidity in our cohort was 15, and 14 for depression.

CONCLUSIONS

The WHO-5 questionnaire is a useful tool to predict depression in adolescents with type 1 diabetes. ROC analysis suggests a slightly higher cut-off for conspicuous questionnaire results compared to previous reports. Due to the high rate of deviant results, adolescents and young adults with type-1 diabetes should be screened regularly for signs of psychiatric comorbidity.

Type 1 diabetes youth with disordered eating: Is there a disproportionate impact on ethnic minorities and indigenous peoples?

Adolescents with type 1 diabetes mellitus consistently have suboptimal glycaemic control and worse outcomes, and this is especially true for adolescents from indigenous communities and ethnic minorities. It is increasingly recognised that disordered eating is common in adolescents and likely causes a disproportionate impact on glycaemic outcomes and psychological morbidity. Eating disorders may be even more common in indigenous and ethnic minority populations and be another reason why it is harder to achieve recommended glycaemic targets in this group. In this viewpoint, we explore the issues around disordered eating in this vulnerable group, the difficulties in diagnosis and the challenges in management. We focus in particular on the outcomes in the more disadvantaged adolescents with type 1 diabetes, especially indigenous groups and ethnic minorities, an area where there have been few publications and generally less recognition to date.
