Assessing fear of hypoglycemia in children with Type 1 diabetes and their parents

The Urgent Need for Breakthrough Therapies and a World Without Type 1 Diabetes

Despite significant progress, type 1 diabetes (T1D) still results in premature death, significant complications, and a substantial daily burden for those affected. T1D remains a lifelong condition that demands constant vigilance and resilience and has a significant social and economic impact. Individuals with T1D must walk a tightrope to minimize disease-related complications that result from insufficient insulin while also avoiding adverse effects from too much insulin. Achieving this balance is challenging, as diet, activity, medications, physiology, the environment, stress, and many other aspects of daily living all affect glucose levels, often differently from day to day. Persistent challenges of T1D go beyond maintaining glycemic control and include managing long-term complications and preventing potentially life-threating adverse reactions from insulin therapy, and the emotional and cognitive burdens that often lead to diabetes distress and burnout. The T1D community-researchers, sponsors, clinicians, those living with T1D, and advocates-must look beyond managing symptoms of T1D and aim for better treatments and to bring cures. Emerging therapies need clear and efficient regulatory pathways, and new solutions are needed to address ongoing regulatory challenges. The perspectives of people with T1D must be front and center in research and regulatory decision-making. Through the collective efforts of the T1D community, the urgent needs of those with T1D can be met, and T1D can be made a thing of the past.

Use of Freestyle Libre 2.0 in children with type 1 diabetes mellitus and elevated HbA1c: Extension phase results after a 12-week randomized controlled trial

AIM

To investigate extension phase outcomes with intermittently scanned continuous glucose monitoring (isCGM 2.0) in children with type 1 diabetes mellitus (T1DM) and elevated HbA1c (7.5-12.2% [58-110 mmol/mol]).

METHODS

One hundred children with T1DM aged 4-13 years were initially in a 12-week randomised controlled trial (RCT) comparing glycaemic outcomes with isCGM 2.0 (intervention group, n = 49) with self-monitored blood glucose (Control group, n = 51). After the 12-week RCT both groups were offered an extension phase with isCGM 2.0 for another 12 weeks. HbA1c, CGM metrics, psychological outcomes and device utilization attitudes were measured.

RESULTS

After the initial 12-week RCT, 66 participants completed this 12-week extension: 36/49 (73%) and 30/51 (58.8%) from the isCGM/isCGM and Control/isCGM groups, respectively. In the isCGM/isCGM group, time below range 70 mg/dL (3.9 mmol/L) (TBR70) reduced from 10.7 ± 11.3% at baseline to 2.8 ± 2.8% and 2.1 ± 2.4% at 12 and 24 weeks, respectively (p < 0.01 for both 12 and 24 weeks). Glucose test frequency increased from 4.7 (2.7) at baseline to 10.7 (4.6) and 9.2 (4.7) at 12 and 24 weeks, respectively (p < 0.01 for both 12 and 24 weeks). The Control/isCGM group decreased TBR70 from 10.7 ± 7.4% at 12 weeks to 2.9 ± 2.8% at 24 weeks and increased daily glucose test frequency from 3.2 (1.6) to 10.7 (5.4) from 12 to 24 weeks (both p < 0.01). However, HbA1c and time in range (TIR) were non-significant at 24 weeks in both groups.

CONCLUSIONS

Extension phase outcomes with intermittently scanned continuous glucose monitoring (isCGM 2.0) in children with T1DM and elevated HbA1c showed a sustained reduction in hypoglycaemia and increased testing frequency at 24 weeks.

Recurrent education: A promising strategy for enhancing diabetes management and reducing hypoglycemia in children with type 1 diabetes

BACKGROUND

This study aimed to assess the impact of recurrent individualized education on the management of hypoglycemia, hypoglycemia awareness, and metabolic control of diabetes in children and adolescents living with type 1 diabetes (T1D).

METHODS

A prospective quantitative study involving participants aged 8 to 18 years with T1D was conducted. Three established hypoglycemia screening tools were employed: the Hypoglycemia Fear Survey (HFS), the Gold Hypoglycemia Awareness Questionnaire, and the Edinburgh Hypoglycemia Symptoms Scale. The participants used blinded continuous glucose monitoring (b-CGM) devices to document glucose values, meals, insulin doses, exercise periods, symptomatic hypoglycemia episodes, and glucose levels during hypoglycemia, experienced symptoms, and treatment approaches for hypoglycemia. Following this initial phase, the participants received education from healthcare professionals. The same procedures were repeated six weeks after the educational intervention.

RESULTS

Prior to education, approximately half (n = 21) of the 47 participants were present with impaired hypoglycemia awareness (IHA), and half of the IHA group applied the appropriate hypoglycemia self-treatment. After education, almost all participants demonstrated an improved ability to manage hypoglycemia effectively. Following education, improvements in the frequency of fingerstick glucose measurement per day, time spent within the target glucose range (70-180 mg/dL), glycemic variability (GV), hypoglycemia perception, appropriate hypoglycemia self-treatment, and hypoglycemia fear were observed, both in participants with hypoglycemia awareness and those with IHA.

CONCLUSIONS

The results indicate that children and adolescents living with T1D benefit from recurrent self-management education. The benefits were observed in both participants with hypoglycemia awareness and those with IHA. Education positively impacts diabetes management and enhances hypoglycemia awareness.

Advanced Hybrid Closed Loop Algorithm Use in Type 1 Diabetes: The French MiniMed™ Glycemic Control and Quality of Life Study

INTRODUCTION

The MiniMed™ 780G system uses an advanced hybrid closed loop algorithm to improve outcomes in people with type 1 diabetes (T1D). The MiniMed™ 780G Glycemic Control and Quality of Life (EQOL) study aimed to provide routine clinical practice data on system effectiveness and associated patient-reported outcomes (PROs) in France.

METHODS

Individuals aged ≥ 7 years with T1D were enrolled. A 14-day run-in phase in Manual mode preceded a 12-month study phase using Auto mode. The primary endpoint was absolute change in time in range (TIR) from baseline to 6 months. Secondary endpoints included changes in glycemic targets, glycated hemoglobin (HbA1c), and hypoglycemia. PROs included treatment satisfaction, quality of life (QoL), and fear of hypoglycemia.

RESULTS

Two-hundred seventy participants formed the intent-to-treat population at 6 months. TIR increased by 11.8 percentage points (standard deviation [SD] 8.96, 95% confidence interval 10.7 to 12.9, p < 0.0001), from 61.9% (SD 11.0) to 73.7% (SD 7.4), equivalent to 2.8 h per day more in range. Time < 70 mg/dL decreased by 1.5 percentage points (p < 0.0001), from 4.0% to 2.5%. All glycemic parameters significantly improved. HbA1c decreased by 0.52% and 0.42% at 6 and 12 months, respectively. More patients met glycemic targets, while severe hypoglycemia was reduced. At 12 months, treatment satisfaction increased across age groups, and QoL improved in adults. Fear of hypoglycemia decreased in adults and children.

CONCLUSION

In France, people with T1D initiating the MiniMed™ 780G system demonstrated sustained TIR and HbA1c improvements. System usage reduced hypoglycemia and fear of hypoglycemia, and increased treatment satisfaction.

Prevalence and associating variables with fear of progression in Chinese pediatric cancer patients: A cross-sectional study

Fear of progression (FoP) is a prevalent psychological strain for cancer patients associated with poor quality of life and psychological morbidity. However, little evidence exists on FoP in children with cancer. Our study aimed to determine prevalence and correlates of FoP of cancer in children. From December 2018 to March 2019, cancer patients from Children's Hospital in Chongqing, Southwest China, were recruited. A Chinese version of Fear of Progression Questionnaire-Short Form (FoP-Q-SF) was adopted to assess children' FoP. Descriptive statistics (percentages, median, and interquartile range), non-parametric tests, and multiple regression analyses were performed on these data. Prevalence of high-level FoP was 43.75% among these 102 children. Multiple regression analysis showed that reproductive system tumors (beta = 0.315, t = 3.235 95% CI [3.171, 13.334]), and level of psychological care needs (beta = -0.370, t = -3.793 95% CI [-5.396, -1.680]) were independent predictors of FoP. Regression model explained 27.10% of all included variables (adjusted R square = 27.10%). As with adults with cancer, children with cancer also have FoP. More attention should be paid to FoP in children with reproductive tumors and in children who need psychological support. More access to psychological support should be offered to reduce FoP and to improve their quality of life.

Glycemic and Psychosocial Outcomes of Advanced Hybrid Closed-Loop Therapy in Youth With High HbA1c: A Randomized Clinical Trial

OBJECTIVE

To determine the efficacy of advanced hybrid closed-loop (AHCL) therapy in a high-risk cohort of youth on continuous subcutaneous insulin infusion (CSII) with or without continuous glucose monitoring (CGM) with suboptimal glycemia.

RESEARCH DESIGN AND METHODS

In a 6-month multicenter clinical trial, youth with type 1 diabetes with mean and most recent HbA1c >8.5% (65 mmol/mol) were randomly assigned 1:1 to AHCL or treatment as usual (CSII ± CGM). The primary outcome was the 24-week between-group difference in HbA1c. Secondary outcomes included CGM metrics from masked CGM and psychological measures (youth-reported problem areas in diabetes [PAID], quality of life, anxiety, depression, and hypoglycemia fear) assessed using validated questionnaires.

RESULTS

A total of 42 participants were randomized (mean [SD] age 16.2 [2.5] years, HbA1c 9.8 [1.1]% or 84 [12] mmol/mol, PAID score 50.3 [19.8]). At study end, the mean (SD) HbA1c was 8.8 (1.1)% or 73 (12) mmol/mol with AHCL and 9.9 (1.2)% or 85 (13.1) mmol/mol with CSII ± CGM, with mean adjusted group difference of -0.77% (95% CI -1.45 to -0.09) or -8.4 mmol/mol (-15.8 to -1.0); P = 0.027. AHCL increased time in range 70-180 mg/dL (difference 19.1%; 95% CI 11.1 to 27.1), reduced time >180 mg/dL (difference -17.7%; 95% CI -26.6 to -8.8), with no increase in time spent <70 mg/dL (difference -0.8%; 95% CI -2.7 to 0.6). There was no evidence for difference in psychosocial outcomes between the two groups at study end.

CONCLUSIONS

AHCL should be encouraged in youth with suboptimal glycemia, as AHCL improves glycemia. However, psychological support remains vital, as technology alone may not be able to reduce the burden of diabetes care in this subgroup.

Shorter Digestion Times of Donor Islets Is Associated With Better Islet Graft Function After Islet Transplantation

Although islet transplantation is effective in reducing severe hypoglycemia events and controlling blood glucose in patients with type 1 diabetes, maintaining islet graft function long-term is a significant challenge. Islets from multiple donors are often needed to achieve insulin independence, and even then, islet function can decline over time when metabolic demand exceeds islet mass/insulin secretory capacity. We previously developed a method that calculated the islet graft function index (GFI) and a patient's predicted insulin requirement (PIR) using mathematical nonlinear regression. Both PIR and GFI could be used by physicians as tools to monitor islet graft function and to guide supplementing the patient with exogenous insulin to prevent beta-cell exhaustion. This study investigates the factors relating to the islet preparation process, as well as donor and recipient characteristics, and assessed their associations with PIR and GFI after transplantation. The goal is to determine the most relevant factors that influence islet graft function after transplantation. We examined the effects of donor and recipient characteristics, and islet processing factors on posttransplanted PIR and GFI. The PIR and GFI at 3 months were calculated using patients' baseline insulin intake, posttransplant 2-h postprandial blood glucose, and glucagon-stimulated C-peptide. Thirteen transplants that resulted in progressive decline in patients' weekly averaged insulin intake over the initial weeks after transplant (assuming constant glucose level) with available 3-month PIR and GFI data were chosen for the investigation. Univariate analyses were performed to assess the effects of donor and recipient characteristics and islet processing factors on islet graft function as reflected by PIR and GFI. The PIR and GFI were treated as continuous response variables in separate linear regression models. Shorter digestion time of isolated donor islets were associated with lower PIR (P = 0.014) and a higher GFI (P = 0.027) after transplantation. Islet injury related to digestion enzyme exposure influenced islet function as estimated using PIR and GFI post-transplantation.

Fear of hypoglycemia and sleep in children with type 1 diabetes and their parents

Aims

To compare impact of pump treatment and continuous glucose monitoring (CGM) with predictive low glucose suspend (SmartGuard) or user initiated CGM (iscCGM) on sleep and hypoglycemia fear in children with type 1 Diabetes and parents.

Methods

Secondary analysis of data from 5 weeks pump treatment with iscCGM (A) or SmartGuard (B) open label, single center, randomized cross-over study was performed. At baseline and end of treatment arms, sleep and fear of hypoglycemia were evaluated using ActiGraph and questionnaires.

Results

31 children (6-14 years, male: 50%) and 30 parents (28-55 years) participated. Total sleep minutes did not differ significantly for children (B vs. A: -9.27; 95% CI [-24.88; 6.34]; p 0.26) or parents (B vs. A: 5.49; 95% CI [-8.79; 19.77]; p 0.46). Neither daytime sleepiness nor hypoglycemia fear in children or parents differed significantly between the systems. Neither group met recommended sleep criteria.

Conclusion

Lack of sleep and fear of hypoglycemia remain a major burden for children with diabetes and their parents. Whilst no significant differences between the systems were found, future technology should consider psychosocial impacts of diabetes and related technologies on children and parents' lived experience to ensure parity of esteem between physical and mental health outcomes.

Automated Insulin Delivery for Young People with Type 1 Diabetes and Elevated A1c

BACKGROUND

Automated insulin delivery is the treatment of choice in adults with type 1 diabetes. Data are needed on the efficacy and safety of automated insulin delivery for children and youth with diabetes and elevated glycated hemoglobin levels.

METHODS

In this multicenter, open-label randomized controlled trial, we assigned patients with type 1 diabetes in a 1:1 ratio either to use an automated insulin delivery system (MiniMed 780G) or to receive usual diabetes care of multiple daily injections or non--automated pump therapy (control). The patients were children and youth (defined as 7 to 25 years of age) with elevated glycemia (glycated hemoglobin ≥8.5% with no upper limit). The primary outcome was the baseline-adjusted between-group difference in glycated hemoglobin at 13 weeks.

RESULTS

A total of 80 patients underwent randomization (37 to automated insulin delivery and 43 to control) and all patients completed the trial. At 13 weeks, the mean (±SD) glycated hemoglobin decreased from 10.5±1.9% to 8.1±1.8% in the automated insulin delivery group but remained relatively consistent in the control group, changing from 10.4±1.6% to 10.6±1.8% (baseline-adjusted between-group difference, -2.5 percentage points; 95% confidence interval [CI], -3.1 to -1.8; P<0.001). Patients in the automated insulin delivery group spent on average 8.4 hours more in the target glucose range of 70 to 180 mg/dl than those in the control group. One severe hypoglycemia event and two diabetic ketoacidosis events occurred in the control group, with no such events in the automated insulin delivery group.

CONCLUSIONS

In this trial of 80 children and youth with elevated glycated hemoglobin, automated insulin delivery significantly reduced glycated hemoglobin compared with usual diabetes care, without resulting in severe hypoglycemia or diabetic ketoacidosis events.

Evaluation of the possible impact of the fear of hypoglycemia on diabetes management in children and adolescents with type 1 diabetes mellitus and their parents: a cross-sectional study

PURPOSE

Hypoglycemia represents a significant source of anxiety for children with type 1 diabetes mellitus (T1DM) and their caretakers. Fear of hypoglycemia (FoH) was measured in children and adolescents with T1DM as well as in their parents using an established research instrument, the Hypoglycemia Fear Survey (HFS).

METHODS

This is a two-center, cross-sectional study involving 100 children and adolescents aged 6-18 years old diagnosed with T1DM. One parent of each child also participated in the study. The participants, who were recruited from two different pediatric endocrine outpatient clinics, were asked to complete the translated Greek version of the HFS, which includes one version for children (C-HFS) and one for parents (P-HFS). The association of the questionnaire responses with subjects' characteristics, such as current age, age at diagnosis, duration of diabetes, HbA1c levels, and mode of diabetes treatment were assessed.

RESULTS

Parents exhibited significantly higher mean HFS scores than their children. No significant correlation was found between the P-HFS or the C-HFS scores and the age of the children, duration of diabetes, HbA1c, or mode of treatment.

CONCLUSION

The finding that parents experience higher levels of FoH compared to their children emphasizes the importance of healthcare providers to screen parental FoH and focus on approaches to support them in order to reduce their psychological burden, thus optimizing children's diabetes management.

Fear of hypoglycemia in parents of children with type 1 diabetes trained for intranasal glucagon use

OBJECTIVE

To investigate fear of hypoglycemia (FoH) in parents of children with type 1 diabetes (T1D) before and after undergoing training to learn intranasal (IN) glucagon administration.

METHOD

In this pre-test/post-test uncontrolled study 364 caregivers of patients with T1D (6-18 years) completed questionnaires measuring sociodemographic characteristics, diabetes-related factors (e.g., type of insulin therapy, glycemic control), and parents' trait anxiety. Parents' FoH was assessed at baseline (T0, training) and after nine months (T1). Two repeated-measure mixed analyses of covariance (ANCOVA) compared the FoH at T0 and at T1 and analyzed the moderating roles of anxiety proneness and type of insulin therapy, as well as of anxiety proneness and use of sensor. Age, T1D duration, HbA1c values, and SES were included as covariates.

RESULTS

Parental FoH at T1 (M = 1.72; SE = 0.06/M = 1.57; SE = 0.09) was significantly lower than parental FoH at T0 (M = 1.89; SE = 0.06/M = 1.77; SE = 0.09). The group with high trait-anxiety had a higher level of FoH (M = 2.05; SE = 0.08/M = 1.89; SE = 0.12) than the group with low trait-anxiety (M = 1.57; SE = 0.08/M = 1.46; SE = 0.09) at both time points. SES was negatively associated with FoH at T0 (t = -2.87; p = .004/t = -2.87; p = .005). No other significant effects were found.

CONCLUSIONS

Training and educating parents on IN glucagon use can help them effectively manage hypoglycemic episodes and alleviate the fear that generally accompany such events.

Ustekinumab for type 1 diabetes in adolescents: a multicenter, double-blind, randomized phase 2 trial

Immunotherapy targeting the autoimmune process in type 1 diabetes (T1D) can delay the loss of β-cells but needs to have minimal adverse effects to be an adjunct to insulin in the management of T1D. Ustekinumab binds to the shared p40 subunit of interleukin (IL)-12 and IL-23, targeting development of T helper 1 cells and T helper 17 cells (TH1 and TH17 cells) implicated in the pathogenesis of T1D. We conducted a double-blind, randomized controlled trial of ustekinumab in 72 adolescents aged 12-18 years with recent-onset T1D. Treatment was well tolerated with no increase in adverse events. At 12 months, β-cell function, measured by stimulated C-peptide, was 49% higher in the intervention group (P = 0.02), meeting the prespecified primary outcome. Preservation of C-peptide correlated with the reduction of T helper cells co-secreting IL-17A and interferon-γ (TH17.1 cells, P = 0.04) and, in particular, with the reduction in a subset of TH17.1 cells co-expressing IL-2 and granulocyte-macrophage colony-stimulating factor (IL-2+ GM-CSF+ TH17.1 cells, P = 0.04). A significant fall in β-cell-targeted (proinsulin-specific) IL-17A-secreting T cells was also seen (P = 0.0003). Although exploratory, our data suggest a role for an activated subset of TH17.1 cells in T1D that can be targeted with minimal adverse effects to reduce C-peptide loss, which requires confirmation in a larger study.

The Maintain High Blood Glucose subscale of the child hypoglycemia fear survey: proposed preliminary cut points for screening youth with type 1 diabetes

OBJECTIVE

To improve the clinical utility of the Maintain High Blood Glucose subscale of the Hypoglycemia Fear Surveys (HFS) by identifying clinically meaningful cut points associated with glycemic outcomes.

METHODS

Youth (N = 994; 13.96 ± 2.3 years) with type 1 diabetes and their caregivers (N = 1,111; 72% female) completed the Child or Parent version of the HFS. Modal Score Distribution, Standard Deviation Criterion, and Elevated Item Criterion approaches were used to identify proposed preliminary cut points for the Maintain High Blood Glucose subscale. The association between proposed preliminary cut points was examined with youth glycemic outcomes.

RESULTS

A cut point of ≥7 for the Maintain High Blood Glucose subscale on the Child HFS was associated with a greater percentage of blood glucose readings >180 mg/dl (p < .01), higher mean blood glucose (p < .001), and a higher hemoglobin A1c (p < .05). In subsequent multiple regression analyses, controlling for other factors associated with glycemia, the significant association between scores above ≥7 and higher mean blood glucose and higher hemoglobin A1c remained. A clinically useful cut point was not identified for caregivers. However, elevated youth scores on the Maintain High Blood Glucose subscale were positively associated with elevated caregiver scores (phi = .171, p < .001).

CONCLUSIONS

The proposed preliminary cut point for the Maintain High Blood Glucose subscale will aid the type 1 diabetes care team in identifying youth whose behaviors may be contributing to their suboptimal glycemia.

Protocol for a prospective, multicenter, parallel-group, open-label randomized controlled trial comparing standard care with Closed lOoP In chiLdren and yOuth with Type 1 diabetes and high-risk glycemic control: the CO-PILOT trial

Purpose

Advanced hybrid closed loop (AHCL) systems have the potential to improve glycemia and reduce burden for people with type 1 diabetes (T1D). Children and youth, who are at particular risk for out-of-target glycemia, may have the most to gain from AHCL. However, no randomized controlled trial (RCT) specifically targeting this age group with very high HbA1c has previously been attempted. Therefore, the CO-PILOT trial (Closed lOoP In chiLdren and yOuth with Type 1 diabetes and high-risk glycemic control) aims to evaluate the efficacy and safety of AHCL in this group.

Methods

A prospective, multicenter, parallel-group, open-label RCT, comparing MiniMed™ 780G AHCL to standard care (multiple daily injections or continuous subcutaneous insulin infusion). Eighty participants aged 7-25 years with T1D, a current HbA1c ≥ 8.5% (69 mmol/mol), and naïve to automated insulin delivery will be randomly allocated to AHCL or control (standard care) for 13 weeks. The primary outcome is change in HbA1c between baseline and 13 weeks. Secondary outcomes include standard continuous glucose monitor glycemic metrics, psychosocial factors, sleep, platform performance, safety, and user experience. This RCT will be followed by a continuation phase where the control arm crosses over to AHCL and all participants use AHCL for a further 39 weeks to assess longer term outcomes.

Conclusion

This study will evaluate the efficacy and safety of AHCL in this population and has the potential to demonstrate that AHCL is the gold standard for children and youth with T1D experiencing out-of-target glucose control and considerable diabetes burden.

Trial registration

This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry on 14 November 2022 (ACTRN12622001454763) and the World Health Organization International Clinical Trials Registry Platform (Universal Trial Number U1111-1284-8452).

Di-PEGylated insulin: A long-acting insulin conjugate with superior safety in reducing hypoglycemic events

Although the discovery of insulin 100 years ago revolutionized the treatment of diabetes, its therapeutic potential is compromised by its short half-life and narrow therapeutic index. Current long-acting insulin analogs, such as insulin-polymer conjugates, are mainly used to improve pharmacokinetics by reducing renal clearance. However, these conjugates are synthesized without sacrificing the bioactivity of insulin, thus retaining the narrow therapeutic index of native insulin, and exceeding the efficacious dose still leads to hypoglycemia. Here, we report a kind of di-PEGylated insulin that can simultaneously reduce renal clearance and receptor-mediated clearance. By impairing the binding affinity to the receptor and the activation of the receptor, di-PEGylated insulin not only further prolongs the half-life of insulin compared to classical mono-PEGylated insulin but most importantly, increases its maximum tolerated dose 10-fold. The target of long-term glycemic management in vivo has been achieved through improved pharmacokinetics and a high dose. This work represents an essential step towards long-acting insulin medication with superior safety in reducing hypoglycemic events.

Optimizing Glycemic Outcomes for Children with Type 1 Diabetes

Changes in physical growth, neurocognitive development, and pubertal maturation are some of the challenges to achieving blood glucose targets in children with type 1 diabetes mellitus. To optimize glycemic outcomes, a comprehensive approach is crucial to address psychosocial needs, expand the use of diabetes technology, and diminish health inequities.

Fear of hypoglycemia and illness perception in type II diabetes patients

BACKGROUND

Hypoglycemia, a prevalent acute complication among individuals with type 2 diabetes (T2D), manifests with varied symptoms. Those with diabetes who have previously encountered hypoglycemic episodes commonly develop a Fear of Hyperglycemia (FOH). Illness perception (IP) significantly affects self-care behaviors and health outcomes in individuals diagnosed with T2D.

OBJECTIVE

This study examined the correlation between IP and FOH among T2D patients and predictors of FOH.

METHODS

The present study employed a descriptive-analytical design. The target population for this investigation comprised patients diagnosed T2D who sought medical care at the clinic and endocrinology departments of a hospital affiliated with Alborz University of Medical Sciences. The data collection period spanned from August 2019 to March 2021. A total of 300 individuals were included in the sample. Questionnaires were administered to measure both IP and FOH. Statistical analysis was conducted to examine the association between IP and FOH, as well as to identify the predictors of FOH.

RESULTS

The results of the study indicated a statistically significant relationship between FOH and the mean score of IP among patients with diabetes (p = 0.001, r = 0.393), suggesting a moderate positive correlation between these variables. Additionally, the duration of illness, IP, and level of education were identified as variables that predicted FOH (p < 0.05).

CONCLUSION

The numerous factors that influence FOH in individuals diagnosed with T2D highlight the necessity for strategic planning and training initiatives aimed at enhancing IP and reducing FOH within this specific population. Healthcare providers should prioritize interventions that not only address patients' concerns but also contribute to the improvement of their overall well-being. By implementing such interventions, healthcare providers can optimize diabetes management strategies and ultimately enhance patient outcomes.

The Relationship Between Parent Fear of Hypoglycemia and Youth Glycemic Control Across the Recent-Onset Period in Families of Youth with Type 1 Diabetes

BACKGROUND

This study aims to examine the relationship between parents' fear of hypoglycemia (FH) over a 1-year period and child glucose metrics in 126 families of youth recently diagnosed with type 1 diabetes (T1D).

METHODS

Parents completed the Hypoglycemia Fear Survey for Parents (HFS-P) and uploaded 14 days of glucose data at a baseline, 6-month, and 12-month assessment.

RESULTS

Parents' HFS-P total and worry scores increased to a clinically meaningful degree from baseline to 6-month assessment, while multilevel models revealed within- and between-person variability in parents' HFS-P worry and behavior scores over time associated with child glycemia. Specifically, a significant negative relationship for within-person worry scores suggested that when parents reported higher than their average worry scores, their children recorded fewer glucose values in the target range, while within-person behavior scores suggested that when parents reported lower than their average behavior scores, their children recorded more values above the target range. There was also a negative relationship for between-person behavior scores with child glycated hemoglobin and a positive relationship for between-person behavior scores with child glucose values in the target range.

CONCLUSIONS

In the recent-onset period of T1D, parental FH worry and behavior associated with child glycemia possibly due to changes in parents' perceptions of their child's hypoglycemia risk. The clinically meaningful increases in parent FH in the recent-onset period and the negative association for between-person behavior scores with child glycated hemoglobin suggest that clinics should consider screening parents for FH, especially among parents of children with lower glycemic levels.

How online peer support affects management efficacy and mitigates difficulties of parents caring for children with type 1 diabetes

The proper management of pediatric type 1 diabetes depends substantially on the parents of affected children. Parental psychological traits specifically related to diabetes caregiving influence the quality of their care and management of the disease in their children. Parents often use Facebook groups as sources of peer support and information about diabetes care. The present study aimed to examine the influence of devices used in diabetes management, ascertain the impact of Facebook peer-support groups on parental perceptions of problems and probe parental self-efficacy. 318 parents of children with type 1 diabetes completed an online questionnaire on demographics, diabetes-related data, and diabetes care-related psychological characteristics. Data analysis revealed three variables that determined competence in diabetes management: the utility of information and suggestions offered in the Facebook groups on diabetes; the form of insulin administration and membership in Facebook groups. Our results underpin that peer-support groups on social media platforms can serve as sources of the necessary information, support, and feedback on diabetes management competence for parents of children living with type 1 diabetes, they may thus facilitate parental diabetes management capabilities.

Effects of 12-Week Freestyle Libre 2.0 in Children with Type 1 Diabetes and Elevated HbA1c: A Multicenter Randomized Controlled Trial

Objective: To investigate whether intermittently scanned continuous glucose monitoring (isCGM) reduced glycated hemoglobin (HbA1c) compared with capillary self-monitored capillary blood glucose (SMBG) in children with type 1 diabetes (T1D) and elevated glycemic control. Research Design and Methods: This multicenter 12-week 1:1 randomized, controlled, parallel-arm trial included 100 participants with established T1D aged 4-13 years (mean 10.9 ± 2.3 years) naive to isCGM and with elevated HbA1c 7.5%-12.2% [58-110 mmol/mol] [mean HbA1c was 9.05 (1.3)%] [75.4 (13.9) mmol/mol]. Participants were allocated to 12-week intervention (isCGM; FreeStyle Libre 2.0; Abbott Diabetes Care, Witney, United Kingdom) (n = 49) or control (SMBG; n = 51). The primary outcome was the difference in change of HbA1c from baseline to 12 weeks. Results: There was no evidence of a difference between groups for change in HbA1c at 12 weeks (0.23 [95% confidence interval; CI: -0.21 to 0.67], P = 0.3). However, glucose-monitoring frequency increased with isCGM +4.89/day (95% CI 2.97-6.81; P < 0.001). Percent time below range (TBR) <3.9 mmol/L (70-180 mg/dL) was reduced with isCGM -6.4% (10.6 to -4.2); P < 0.001. There were no differences in within group changes for Parent or Child scores of psychosocial outcomes at 12 weeks. Conclusions: For children aged 4-13 years with elevated Hba1c isCGM led to improvements in glucose testing frequency and reduced time below range. However, isCGM did not translate into reducing Hba1c or psychosocial outcomes compared to usual care over 12-weeks. The trial is registered within the Australian New Zealand Trial Registry on February 19, 2020 (ACTRN12620000190909p; ANZCTR.org.au) and the World Health Organization International Clinical Trials Registry Platform (Universal Trial Number U1111-1237-0090).

Psychosocial Effects of the Loop Open-Source Automated Insulin Delivery System

AIMS

This study examined the psychosocial impact of Loop, an open-source automated insulin dosing system that has emerged from the diabetes technology "Do-It-Yourself" (DIY) movement.

METHODS

Subsamples of 239 adults, 115 children, and 243 parents completed data collection at the time of Loop initiation and 3 and 6 months later. Surveys collected demographic and clinical information, percent time-in-range, HbA1c, and validated psychosocial measures. Analyses included paired t tests and McNemar's tests to compare psychosocial functioning at 3 and 6 months and regression models to assess baseline predictors of psychosocial outcomes at 6 months.

RESULTS

Adults reported significant improvements in diabetes distress (t = -7.20 P < .001; t = -8.01, P < .001), sleep quality (t = 6.81, P < .001; t = 2.98, P = .003), fear of hypoglycemia (t = -4.42, P < .001; t = -4.97, P < .001), and hypoglycemia confidence (t = 8.68, P < .001; t = 7.96 P < .001) from baseline to 3 months and 6 months, respectively. Significant improvements in parents' and children's sleep quality and parents' fear of hypoglycemia were also observed. Several baseline characteristics were associated with psychosocial outcomes at 6 months.

CONCLUSIONS

The current findings support the broad and sustained benefits of Loop across multiple aspects of psychosocial well-being. Advancement and dissemination of such technologies has the potential to improve mental and physiological health among people living with type 1 diabetes.

Hypoglycemia and Cardiovascular Disease: Exploring the Connections

It has long been known that administering insulin or insulin secretagogues to treat diabetes has the unfavorable side effect of hypoglycemia. Because hypoglycemia can disrupt normal brain function, it can have a profound impact on people's lives. Studies have shown a connection between hypoglycemia and a higher risk of death and cardiovascular disease. Through experimental studies, numerous potential reasons for the start of cardiovascular events have been discovered. In addition, studies on people have demonstrated that hypoglycemia can result in ventricular arrhythmias. According to recent studies, a number of factors may affect the relationship between hypoglycemia, cardiovascular events, and mortality. Confounding factors may explain the apparent correlation, at least in part. People with comorbidities may experience more hypoglycemia, increasing their risk of mortality. Those who have type 1 or type 2 diabetes, however, seem to be more susceptible to the negative effects of hypoglycemia on the cardiovascular system. When choosing appropriate glucose-lowering treatments and setting glycemic objectives with patients, clinicians should be aware of this risk.

Psychosocial Impact of the Insulin-Only iLet Bionic Pancreas for Adults, Youth, and Caregivers of Youth with Type 1 Diabetes

Objective: To evaluate the psychosocial impact and user experience for the insulin-only configuration of iLet bionic pancreas (BP) in persons 6-83 years years of age with type 1 diabetes. Research Design and Methods: In this multicenter, randomized controlled, 13-week trial, 275 adults (221 randomly assigned to the BP group and 54 to the standard of care [SC] group) and 165 youth and their caregivers (112 randomly assigned to the BP group and 53 to the SC group) completed psychosocial questionnaires at baseline, mid-study, and the end of the trial. Results: In all age groups, most participants would recommend using the BP, including those with previous experience using automated insulin delivery devices. Similarly, the vast majority of participants reported a high level of perceived benefits and a low number of perceived burdens. Adult participants reported significant decreases in the fear of hypoglycemia and in diabetes-specific emotional distress, as well as improvements in their perceived well-being. Conclusion: Findings demonstrate acceptability, reduced burden, and positive psychosocial outcomes for adults. Children and teenagers also report high acceptability and reduced burden, but less clear improvements in psychosocial outcomes. Clinical Trial Registration Number: NCT04200313.

Glucose control and psychosocial outcomes with use of automated insulin delivery for 12 to 96 weeks in type 1 diabetes: a meta-analysis of randomised controlled trials

BACKGROUND

Glycaemic control of Type 1 Diabetes Mellitus (T1DM) remains a challenge due to hypoglycaemic episodes and the burden of insulin self-management. Advancements have been made with the development of automated insulin delivery (AID) devices, yet, previous reviews have only assessed the use of AID over days or weeks, and potential benefits with longer time of AID use in this population remain unclear.

METHODS

 We performed a systematic review and meta-analysis of randomised controlled trials comparing AID (hybrid and fully closed-loop systems) to usual care (sensor augmented pumps, multiple daily insulin injections, continuous glucose monitoring and predictive low-glucose suspend) for adults and children with T1DM with a minimum duration of 3 months. We searched PubMed, Embase, Cochrane Central, and Clinicaltrials.gov for studies published up until April 4, 2023. Main outcomes included time in range 70-180 mg/dL as the primary outcome, and change in HbA1c (%, mmol/mol), glucose variability, and psychosocial impact (diabetes distress, treatment satisfaction and fear of hypoglycaemia) as secondary outcomes. Adverse events included diabetic ketoacidosis (DKA) and severe hypoglycaemia. Statistical analyses were conducted using mean differences and odds ratios. Sensitivity analyses were performed according to age, study duration and type of AID device. The protocol was registered in PROSPERO, CRD42022366710.

RESULTS

We identified 25 comparisons from 22 studies (six crossover and 16 parallel designs) including a total of 2376 participants (721 in adult studies, 621 in paediatric studies, and 1034 in combined studies) which were eligible for analysis. Use of AID devices ranged from 12 to 96 weeks. Patients using AID had 10.87% higher time in range [95% CI 9.38 to 12.37; p < 0.0001, I2 = 87%) and 0.37% (4.77 mmol/mol) lower HbA1c (95% CI - 0.49% (- 6.39 mmol/mol) to - 0.26 (- 3.14 mmol/mol); p < 0·0001, I2 = 77%]. AID systems decreased night hypoglycaemia, time in hypoglycaemia and hyperglycaemia and improved patient distress, with no increase in the risk of DKA or severe hypoglycaemia. No difference was found regarding treatment satisfaction or fear of hypoglycaemia. Among children, there was no difference in glucose variability or time spent in hypoglycaemia between the use of AID systems or usual care. In sensitivity analyses, results remained consistent with the overall analysis favouring AID.

CONCLUSION

The use of AID systems over 12 weeks, regardless of technical or clinical differences, improved glycaemic outcomes and diabetes distress without increasing the risk of adverse events in adults and children with T1DM.

A systematic review on the impact of commercially available hybrid closed loop systems on psychological outcomes in youths with type 1 diabetes and their parents

AIM

To systematically assess the impact of commercially available hybrid closed loop (HCL) systems on psychological outcomes in youths with type 1 diabetes and their parents.

METHODS

We performed a systematic review including studies published in the last 10 years. PICOS framework was used in the selection process, and evidence was assessed using the GRADE system.

RESULTS

A total of 215 studies were identified after duplicate removal, and 31 studies were included in this systematic review: 20 on first-generation HCL and 11 on second-generation HCL systems. According to studies with moderate- to high-level quality of evidence, HCL systems led to better, or in some studies, unchanged psychological outcomes such as distress and burden related to diabetes management, fear of hypoglycemia, quality of life, satisfaction; instead, quality of sleep was perceived as improved, although results were not confirmed in studies using actigraphy. From semi-structured interviews, answers were more homogeneous, and participants reported a positive experience and attitude towards HCL technology, which was felt to be easy to use and apt to achieve glycemic targets.

CONCLUSIONS

Evidence confirms the importance of evaluating the psychosocial needs of youths with diabetes and their families when starting HCL systems and during follow-up, and to set realistic expectations of what can be achieved along with awareness of the limitations of the systems, and educate and motivate families to overcome barriers.

Healthy weight and overweight adolescents with type 1 diabetes mellitus do not meet recommendations for daily physical activity and sleep

AIMS

Physical activity (PA) plays an important role in the prevention of cardiovascular disease (CVD), particularly in individuals with type 1 diabetes mellitus (T1DM) who are at increased risk. Our aim was to determine levels of moderate-to-vigorous physical activity (MVPA), sedentary behaviour and sleep in adolescents with T1DM, and identify barriers to PA.

METHODS

Participants aged 12-18 with T1DM wore an accelerometer and continuous glucose monitor for 24 h over 7-days. Data was processed into PA metrics and sleep. Pearson correlations were used to test associations between MVPA and metabolic measures. Barriers to PA were measured using a questionnaire.

RESULTS

Thirty-seven adolescents provided valid accelerometer data. Mean daily MVPA was 44.0 min [SD 17.6] with 16.2% achieving the guideline of ≥ 60 min/day. Participants had 11 h [SD 1.2] of sedentary behaviour and 7.6 h [SD 1.5] of sleep/day. There was no difference in MVPA in overweight or obese (53.8%) vs. healthy weight (44.2%) adolescents (45.0 min [SD 16.6] vs. 43.1 min [SD 18.8]). Only 39.6% reported one or more diabetes specific barrier to PA.

CONCLUSION

Adolescents with T1DM engage in insufficient MVPA and sleep, irrespective of body weight status, suggesting the need for targeted interventions.

Translation and Validation Study of the Hypoglycemia Fear Survey in a Greek Population of Children and Adolescents with Type 1 Diabetes Mellitus and their Parents

The present study attempted to translate and culturally adapt an established research instrument, the Hypoglycemia Fear Survey (HFS) questionnaire, to the Greek population and evaluate its validity and internal consistency so that it can be used for the assessment of hypoglycemia fear in Greek children and adolescents with T1DM and their parents. One hundred Greek children and adolescents with T1DM, 54 males, 6-18 years old, and one of their parents participated in this validation study. The participants completed the translated Greek HFS, which includes one version for children (CHFS) and one for parents (PHFS). Exploratory Factor Analysis (EFA) was used to assess construct validity. Internal consistency was assessed using Cronbach's alpha, and convergent validity was established by estimating the correlation coefficients between the scores of the HFS scales/subscales and the different constructs of the Pediatric Quality of Life Inventory. The CHFS and PHFS exhibited adequate internal consistency for the total score and the Worry subscale, but lower consistency for the Behavior subscale. High test-retest reliability was also shown. We conclude that the Greek version of the HFS is a valid and reliable instrument to assess the fear of hypoglycemia in Greek children and adolescents with T1DM and their parents.

Prevalence of fear of hypoglycemia in adults with type 1 diabetes using a newly developed screener and clinician's perspective on its implementation

INTRODUCTION

Fear of hypoglycemia (FoH) affects quality of life, emotional well-being, and diabetes management among people with type 1 diabetes (PwT1D). American Diabetes Association's (ADA) guidelines recommend assessing FoH in clinical practice. However, existing FoH measures are commonly used in research and not in clinical practice. In this study, prevalence of FoH was assessed in PwT1D using a newly developed FoH screener for clinical practice; its association with established measures and outcomes was also determined. In addition, healthcare providers' (HCPs) perspectives on implementing FoH screener into real-world practice were explored.

RESEARCH DESIGN AND METHODS

This multiphase observational study used mixed methods in two phases. First, we collected a cross-sectional survey (including the screener) from PwT1D (≥18 years) from T1D Exchange Quality Improvement Collaborative adult clinics. Pearson correlations and regression analyses were performed on diabetes outcome measures using screener scores. Second, we conducted focus groups among HCPs who treat PwT1D and descriptive analysis to summarize results.

RESULTS

We included 553 PwT1D. Participants had a mean±SD age of 38.9±14.2 years and 30% reported a high FoH total score. Regression analyses showed that higher A1c and higher number of comorbidities were significantly associated with high FoH (p<0.001). High FoH worry and behavior scores were significantly associated with 8-Item Patient Health Questionnaire and 7-Item Generalized Anxiety Disorder Scale scores. Participants with ≥1 severe hypoglycemia event(s) and impaired awareness of hypoglycemia had higher odds of high FoH. Eleven HCPs participated in focus group interviews; they expressed that the FoH screener is clinically necessary and relevant but poses implementation challenges that must be addressed.

CONCLUSIONS

Our results demonstrate FoH is common in PwT1D and affects their psychosocial well-being and diabetes management. In alignment with ADA position statement, HCP focus group results emphasize importance of screening for FoH. Implementing this newly developed FoH screener may help HCPs identify FoH in PwT1D.

The impact of fear of hypoglycaemia on sleep in adolescents with type 1 diabetes

AIMS

Fear of hypoglycaemia (FOH) can contribute to impaired sleep for adults with type 1 diabetes (T1D) and parents of children with T1D, although it is unknown how FOH may affect sleep for adolescents with T1D. This study examines the relationship between adolescent FOH and sleep and assessed the influences of continuous glucose monitor (CGM) and insulin pump use.

METHODS

Adolescents ages 14-18 years with T1D completed questionnaires evaluating FOH (Child Hypoglycemia Fear Survey) and sleep (Pittsburgh Sleep Quality Index, PSQI). Analyses included linear and logistic regression, t-tests and Fisher's exact tests.

RESULTS

Participants included 95 adolescents (52 female) with a median (IQR) age of 16.5 (15.3-17.7) years and a T1D duration of 5.7 (2.5-9.6) years. Analyses showed increased FOH-Worry subscale scores were associated with reduced sleep duration (β = -0.03, p = 0.042, adjusting for BMI z-score, race and ethnicity) and increased sleep disturbances (OR = 1.1, p = 0.038, adjusting for race and ethnicity). Frequent CGM users had longer sleep duration (average 7.5 h) compared with infrequent or non-CGM users (average = 6.8 h; p = 0.029), and pump users had overall improved sleep health as determined by PSQI score (p = 0.019). Technology use did not have significant interactions in the relationships between FOH and sleep duration or sleep disturbances.

CONCLUSIONS

Worrying about hypoglycaemia was associated with impaired sleep for adolescents with T1D. Diabetes technology users have some sleep improvements, but CGM and pump use do little to alter the relationship between FOH and sleep outcomes.

Is fear of hypoglycemia a major barrier to an active lifestyle in children and adolescents with type 1 diabetes? The Diactive-1 Study

Studies on fear of hypoglycemia as a barrier to physical activity among youth with type 1 diabetes (T1D) have been limited and controversial, most of which used self-reported assessment. The aim of the study was to evaluate the relationship between fear of hypoglycemia and physical activity and glycemic metrics in children and adolescents with T1D. Seventy-four participants (6-18 years of age; 44.6% females) with T1D were included in the study. Physical activity was assessed through accelerometry on nine consecutive days, and blood glucose metrics were simultaneously tracked using continuous glucose monitoring (time-in-range and hypoglycemic events). A closed question was used to evaluate the avoidance of physical activity due to fear of hypoglycemia. Fifteen participants (20%) reported avoiding physical activity due to fear of hypoglycemia. The group reporting no fear of hypoglycemia showed lower total physical activity (-35.33 min/day, 95% confidence interval [CI] (-77.57 to -1.47)) and light physical activity (-29.81 min/day, 95% CI -64.01 to -2.75) and higher sedentary time (77.95 min/day, 95% CI 26.46-136.87) per day compared with those with fear of hypoglycemia. No difference was found between those patients with fear of hypoglycemia in terms of meeting the recommendations of glycated hemoglobin, glucose coefficient of variation, and time-in-range when compared to those with no fear of hypoglycemia. In conclusion, children and adolescents with fear of hypoglycemia were more active, less sedentary, and had similar glycemic metrics to those without fear. Our results therefore suggest that fear of hypoglycemia may be less of a barrier to an active lifestyle than previously believed.

Household Food Insecurity and Fear of Hypoglycemia in Adolescents and Young Adults With Diabetes and Parents of Youth With Diabetes

OBJECTIVE

To evaluate the relation between household food insecurity (HFI) and fear of hypoglycemia among young adults with type 1 and type 2 diabetes and adolescents with type 1 diabetes and their parents.

RESEARCH DESIGN AND METHODS

We analyzed cross-sectional data of 1,676 young adults with youth-onset diabetes (84% type 1, 16% type 2) and 568 adolescents (<18 years old; mean age 15.1 years) with type 1 diabetes from the SEARCH for Diabetes in Youth study. Adult participants and parents of adolescent participants completed the U.S. Household Food Security Survey Module. Adults, adolescents, and parents of adolescents completed the Hypoglycemia Fear Survey, where answers range from 1 to 4. The outcomes were mean score for fear of hypoglycemia and the behavior and worry subscale scores. Linear regression models identified associations between HFI and fear of hypoglycemia scores.

RESULTS

Adults with type 1 diabetes experiencing HFI had higher fear of hypoglycemia scores (0.22 units higher for behavior, 0.55 units for worry, 0.40 units for total; all P < 0.0001) than those without HFI. No differences by HFI status were found for adolescents with type 1 diabetes. Parents of adolescents reporting HFI had a 0.18 unit higher worry score than those not reporting HFI (P < 0.05). Adults with type 2 diabetes experiencing HFI had higher fear of hypoglycemia scores (0.19 units higher for behavior, 0.35 units for worry, 0.28 units for total; all P < 0.05) than those in food secure households.

CONCLUSIONS

Screening for HFI and fear of hypoglycemia among people with diabetes can help providers tailor diabetes education for those who have HFI and therefore fear hypoglycemia.

Psychosocial Assessment Tools for Youth with Type 1 Diabetes: a 10-Year Review

PURPOSE OF REVIEW

There is a notable lack of consistency in the measurement of psychosocial factors affecting youth with type 1 diabetes, resulting in a need for increased measurement standardization and establishment of measures tailored to capture unique experiences faced by youth. This review sought to assess 10 years of extant literature (2011 to 2020) to identify which established measurement tools are commonly used and to evaluate new measurement tools that were introduced during this period.

RECENT FINDINGS

There are a variety of psychosocial factors affecting youth, and assessment of these measures has shown substantial variability. Our review found that most frequently cited scales were those pertaining to self-efficacy, diabetes distress, family conflict, autonomy, and fear of hypoglycemia. During our review period, experts developed and validated 21 new scales, the majority of which sought to evaluate areas pertaining to diabetes distress. Of the common scales and newly developed scales identified in this review, psychometric properties showcase high reliability and validity, and items are becoming increasingly specific to youth but still lack assessment of how youth perceive technology's impact on diabetes management. The field would benefit from measures employing more nuanced age specificity and addressing technology usage.

Modified e-Delphi Process for the Selection of Patient-Reported Outcome Measures for Children and Families With Type 1 Diabetes Using Continuous Glucose Monitors: Delphi Study

BACKGROUND

Type 1 diabetes (T1D) management is complex and associated with significant psychosocial burden. Continuous glucose monitors (CGM) can improve disease management and outcomes and introduce new or exacerbate existing psychosocial concerns. Patient-reported outcome measures (PROMs) can be used to capture this information, but there is no consensus on which PROMs should be used in pediatric CGM research.

OBJECTIVE

Here we describe the process to (1) identify PROMs that could be used to assess the impact of CGMs on pediatric patients with T1D, (2) implement a modified electronic Delphi (e-Delphi) methodology to arrive at an expert consensus on which PROMs are most suitable for clinical and research applications, and (3) establish a periodicity table for the administration of PROMs over time in a real-world evidence study.

METHODS

To identify appropriate PROMs for pediatric patients and families with T1D and CGMs, we conducted an asynchronous, e-Delphi process with a multidisciplinary group of experts from around the country. We identified candidate instruments through a literature review. The 3-round e-Delphi process was conducted via a study website, email, and web-based forms. Participants provided opinions on the usefulness of instruments, age validation, feasibility, time, and frequency of administration.

RESULTS

In total, 16 experts participated in the e-Delphi process; 4 of whom consistently participated in all 3 rounds. We identified 62 candidate instruments, which were narrowed down to 12 final PROMs across 5 domains: diabetes distress and burden (n=4), autonomy (n=2), quality of life (n=1), psychosocial (n=3), and technology acceptance (n=2). A quarterly administration schedule was developed to reduce burden on participants.

CONCLUSIONS

PROMs can provide critical insights into the psychosocial well-being of patients. The specific measures identified in the paper are particularly well suited for pediatric patients with T1D using CGMs. Clinical implementation could help health care providers, patients, and families to engage in more comprehensive disease management.

Sweet but sour: Impaired attention functioning in children with type 1 diabetes mellitus

Children diagnosed with type 1 diabetes mellitus (T1DM) are at risk for neurocognitive sequelae, including impaired attention functioning. The specific nature of the cognitive deficit varies; current literature underscores early age of diabetes diagnosis and increased disease duration as primary risk factors for this neurocognitive decline. Forty-three children with T1DM were evaluated for Attention Deficit/Hyperactivity Disorder (ADHD) symptomatology using the MOXO continuous performance test (MOXO-CPT) performed during a routine outpatient evaluation. The study cohort demonstrated a significant decline in all four domains of attention functioning. The effect was most pronounced with early age at T1DM diagnosis, a longer disease duration and with poorer glycemic control (represented by higher HbA1c values). With increased disease duration (of 5 plus years), acute hyperglycemia was associated with inattention in the real-time setting. These findings highlight the need for routine screening of neurocognitive function in children with T1DM so that early intervention can be employed during this crucial period of cognitive development.

Related factors associated with fear of hypoglycemia in parents of children and adolescents with type 1 diabetes - A systematic review

PROBLEM

Fear of hypoglycemia is a significant concern for parents of children/ adolescents with type 1 diabetes. Although some studies have explained the parental fear of hypoglycemia, the related factors were yet to be determined. This systematic review aims to identify the related factors of fear of hypoglycemia in the parents of children and adolescents with type 1 diabetes and provide a theoretical basis for further intervention.

ELIGIBILITY CRITERIA

PubMed, MEDLINE, EMBASE, Scopus, CINAHL, EBSCO, Web of Science, and Cochrane Library were systematically searched from 2010 to 2021. Studies evaluating the fear of hypoglycemia of parents and its associated factors were included.

SAMPLE

Twenty-three observational articles met the criteria.

RESULTS

Significant associations were found between fear of hypoglycemia and specific factors, including motherhood, nocturnal hypoglycemia, and the number of blood glucose monitoring. Psychological factors, including anxiety, depression, pediatric parenting stress, mindfulness, self-efficacy, quality of life, and sleep disorders, were conclusive and associations with parental fear of hypoglycemia.

CONCLUSIONS

Understanding parental fear of hypoglycemia can help parents prevent potential problems in diabetes management, thus promoting children's growth. According to current evidence, effective targeted interventions based on modifiable relevant factors can be developed to reduce the fear of hypoglycemia in parents while maintaining optimal blood glucose control in children/ adolescents.

IMPLICATIONS

Health professionals should pay more attention to the mental health of parents, and parents should be involved in the care plan and have the opportunity to discuss their fear of hypoglycemia in the most appropriate way to manage type 1 diabetes.

Real-world prospective observational single-centre study: Hybrid closed loop improves HbA1c, time-in-range and quality of life for children, young people and their carers

Hybrid closed-loop (HCL) systems are characterised by integrating continuous glucose monitoring (CGM) with insulin pumps which automate insulin delivery via specific algorithms and user-initiated insulin delivery. The aim of the study was to evaluate the effectiveness of HCLs on Hba1c, time-in-range (TIR), time in hypoglycaemia, fear of hypoglycaemia, sleep and quality of life measure in children and young people (CYP) with T1D and their carers. Data on HbA1c, TIR and hypoglycaemia frequency were reviewed at baseline prior to starting HCL and 3 months after commencement. As part of clinical care, all patients and carers were provided with key education on the use of the HCL system by trained diabetes healthcare professionals. CYP aged 12 years and above independently completed the validated Hypoglycaemia Fear Survey (HFS). Parents of patients <12 were asked to complete a modified version of the HFS-Parent (HFS-P) survey. There were 39 CYP (22 men) with T1D included with a mean age of 11.8 ± 4.4 at commencement of HCL. Median duration of diabetes was 3.8 years (interquartile range 1.3-6.0). There were 55% of patients who were prepubertal at the time of HCL commencement. 91% were on the Control-IQ system and 9% on the CamAPS FX system. HCL use demonstrated significant improvements at 3 months in the following: HbA1c in mmol/mol (63.0 vs. 56.6, p = 0.03), TIR (50.5 vs. 67.0, p = 0.001) and time in hypoglycaemia (4.3% vs. 2.8%, p = 0.004). HFS scores showed improved behaviour (34.0 vs. 27.5.9, p = 0.02) and worry (40.2 vs. 31.6, p = 0.03), and HFS-P scores also showed improved behaviour (p < 0.001) and worry (p = 0.01). Our study shows that HCL at 3 months improves glucose control, diabetes management and quality of life measures such as fear and worry of hypoglycaemia for CYP and carers.

Bring Blood Glucose Down! An intervention to reduce fear of hypoglycemia in caregivers of adolescents with type 1 diabetes: Study design and participant characteristics

Fear of hypoglycemia (FOH) is anxiety or extreme worry about having a low blood glucose and its consequences. FOH is common in individuals with type 1 diabetes (T1D) of all ages, as well as their caregivers, and can lead to inappropriate T1D self-management and suboptimal health outcomes. Despite its prevalence and serious health consequences, there has been very little attention focused on developing interventions to reduce FOH and its associated maladaptive T1D management behaviors. The primary aim of the present study, Bring BG Down!, was to implement a pilot intervention targeting FOH in mothers of adolescents with T1D. Exploratory aims included determining if the intervention had an impact on the adolescent's FOH, glycemia, as well as other generalized anxiety symptoms or symptoms of obsessive-compulsive disorder in both the mother and adolescent. Caregiver participants and their adolescents with T1D were randomized to either the Bring BG Down! group or the Control group. Individuals in the Bring BG Down! group participated in intervention sessions for 6 months via telehealth and they completed questionnaires, whereas those in the Control group only completed questionnaires. Follow-up occurred at 7-months and 10-months. The purpose of this paper is to describe the Bring BG Down! study design and rationale, and participant characteristics at the start of the study.

The effect of do-it-yourself real-time continuous glucose monitoring on psychological and glycemic variables in children with type 1 diabetes: A randomized crossover trial

BACKGROUND

Continuous glucose monitoring (CGM) decreases fear of hypoglycemia (FOH) and improves glycemic control among those affected by type 1 diabetes (T1D). No studies to date have examined the impact of using do-it-yourself real-time continuous glucose monitoring (DIY RT-CGM) on psychological and glycemic outcomes.

METHODS

Child-parent dyads were recruited for a multicentre randomized crossover trial. Children with T1D were current intermittently scanned CGM (isCGM) users and aged 2-13 years. Families received either 6 weeks of DIY RT-CGM with parental remote monitoring (intervention) or 6 weeks of isCGM plus usual diabetes care (control), followed by a 4-week washout period, then crossed over. The primary outcome was parental FOH. Secondary outcomes were glycemic control using traditional CGM metrics, as well as a range of other psychosocial measures.

FINDINGS

Fifty five child-parent dyads were recruited. The child mean age was 9.1 ± 2.8 years. Although, there was no effect on parental FOH, -0.1 (95%CI: -0.3, 0.1, p = 0.4), time-in-range (TIR) (%3.9-10 mmol/L) was significantly higher with DIY RT-CGM over isCGM (54.3% ± 13.7 vs. 48.1% ± 13.6), mean difference, 5.7% (95%CI 1.8, 9.6, p <0.004). There was no difference for time spent in hypoglycemia. Parent diabetes treatment satisfaction was significantly higher following DIY RT-CGM compared to isCGM, mean difference 5.3 (95%CI: 2.3, 8.2, p <0.001).

CONCLUSION

The use of DIY RT-CGM versus isCGM did not improve parental FOH; however, TIR and parental satisfaction with diabetes treatment were significantly improved. This suggests in the short term, DIY RT-CGM appears safe and may offer families some clinically important advantages over isCGM.

Letting the World See through Your Eyes: Using Photovoice to Explore the Role of Technology in Physical Activity for Adolescents Living with Type 1 Diabetes

This paper qualitatively explores how technologies and physical activity are experienced by adolescents with type 1 diabetes. Type 1 diabetes is a life-threatening autoimmune condition, which is highly prevalent in young children. Physical activity is underutilised as part of treatment goals due to multifactorial challenges and lack of education in both the family setting and across society as a whole. Using photovoice methodology, 29 participants (parents and adolescents), individually or as dyads, shared and described in reflective journal format examples of technology and physical activity in their lives. In total, 120 personal photographs with accompanying narratives were provided. The data were thematically coded by the researcher and then collaboratively with participants. Four key themes (and 12 subthemes) were generated including: (i) benefits of technology; (ii) complexity and difficulty; (iii) emotional impact; (iv) reliance and risk. Findings demonstrate that current technology does not address the complex needs of adolescents with type 1 diabetes to enable participation in physical activity without life risk. We conclude from our findings that future technologies for supporting engagement in physical activity as part of diabetes management need to be: more interoperable, personalised and integrated better with ongoing education and support.

Discontinued Use of the Loop Insulin Dosing System: A Mixed-Methods Investigation

Background: Loop is an open-source automated insulin dosing system that allows users unrivaled control over system settings that affect future glucose prediction. Thousands use Loop, but little is known about those who discontinue. Methods: In a large observational study, 874 Loop participants completed surveys and provided glycemic data, 46 (5.3%) of those self-identified as discontinuing Loop use during the observation window, 45 completed a discontinued use survey, 22 provided system settings data, and 19 participated in semistructured interviews about their discontinuation. Qualitative data were transcribed, coded, and analyzed. Results: Older age and not trusting Loop were associated with discontinued use, although no other demographic or clinical characteristics were significant correlates. The most endorsed reasons were "I decided to try something else" (27.8%) followed by "It just didn't help as much as I thought it would" (22.2%). Qualitative analyses revealed prominent themes centered upon mental and emotional burden and adjusting settings. Other reasons for discontinued use included fear of disapproval of Loop use from diabetes provider, barriers to acquiring component devices, a desire to try new/different technologies, concerns that Loop could not accommodate specific exercise or low insulin dose regimens, and worry about Loop use during pregnancy. It was noted that burdens might be alleviated by enhanced technical assistance and expert guidance. Conclusions: Although the majority of individuals in the Loop observational study continued use, those who discontinued reported similar challenges. Technical support and education specific to setting calculations could expand Loop benefits, alleviate burden, and support sustained use among new Loop users.

Predicting Success with a First-Generation Hybrid Closed-Loop Artificial Pancreas System Among Children, Adolescents, and Young Adults with Type 1 Diabetes: A Model Development and Validation Study

Background: Hybrid Closed-Loop (HCL) systems aid individuals with type 1 diabetes in improving glycemic control; however, sustained use over time has not been consistent for all users. This study developed and validated prognostic models for successful 12-month use of the first commercial HCL system based on baseline and 1- or 3-month data. Methods and Materials: Data from participants at the Barbara Davis Center (N = 85) who began use of the MiniMed 670G HCL were used to develop prognostic models using logistic regression and Lasso model selection. Candidate factors included sex, age, duration of diabetes, baseline hemoglobin A1c (HbA1c), race, ethnicity, insurance status, history of insulin pump and continuous glucose monitor use, 1- or 3-month Auto Mode use, boluses per day, and time in range (TIR; 70-180 mg/dL), and scores on behavioral questionnaires. Successful use of HCL was predefined as Auto Mode use ≥60%. The 3-month model was then externally validated against a sample from Stanford University (N = 55). Results: Factors in the final model included baseline HbA1c, sex, ethnicity, 1- or 3-month Auto Mode use, Boluses per Day, and TIR. The 1- and 3-month prognostic models had very good predictive ability with area under the curve values of 0.894 and 0.900, respectively. External validity was acceptable with an area under the curve of 0.717. Conclusions: Our prognostic models use clinically accessible baseline and early device-use factors to identify risk for failure to succeed with 670G HCL technology. These models may be useful to develop targeted interventions to promote success with new technologies.

Fear of hypoglycemia in children with type 1 diabetes and their parents: Validation of the Italian version of the Hypoglycemia Fear Survey for Children and for Parents

BACKGROUND

Currently, Italian versions of the Hypoglycemia Fear Survey for Children (CHFS) and for Parents (PHFS) quantifying Fear of Hypoglycemia (FoH) in pediatric diabetes are not available.

OBJECTIVE

To validate the Italian version of the CHFS and PHFS.

SUBJECTS AND METHODS

One hundred and seventy-four children with type 1 diabetes aged 6-18 and 178 parents completed the CHFS and PHFS, the PedsQL 3.0 Diabetes module and the KIDSCREEN-10. Internal consistency was good (α = 0.85 for CHFS, α = 0.88 for PHFS); validity was supported by correlations of CHFS total score (CHFS-T r = -0.50; p < 0.001, CI = -0.62 to -0.35) and Worry subscale (CHFS-W r = -0.49; p < 0.001, CI = -0.62 to -0.32) with measures of health-related quality of life (QoL), which were not related to PHFS scores. Factor analyses justified the structure and the separate scoring of Behavior and Worry subscales. Children's age was negatively correlated with CHFS-T (r = -0.16; p = 0.03, CI = -0.36 to 0.00), CHFS-W (r = -0.29; p = 0.02, CI = -0.39 to -0.07), PHFS-T (r = -0.20; p = 0.006, CI = -0.35 to -0.04), PHFS-B (r = -0.30; p = 0.001, CI = -0.43 to -0.17). Mean (SD) item scores of CHFS-T (1.47 ± 0.56 vs. 1.27 ± 0.57; p < 0.05) and CHFS-W (1.20 ± 0.73 vs. 0.96 ± 0.68; p < 0.05) were higher in children with HbA1c ≥7.5%. Higher levels of distress for upsetting hypoglycemia were associated with lower child's QoL scores as perceived by children (Peds-QL: 72.6 ± 12.8 vs. 80.4 ± 11.9; p < 0.001) and parents (Peds-QL: 70.6 ± 13.8 vs. 75.8 ± 12.9; p < 0.05).

CONCLUSION

The Italian version of CHFS and PHFS appears to be a valid measure to assess FoH in clinical practice and factor analysis supports separate scoring for the Worry and Behavior subscales.

Fear of hypoglycemia and quality of life in young people with type 1 diabetes and their parents in the era of sensor glucose monitoring

INTRODUCTION

It is crucial to understand psychosocial outcomes in children and adolescents with type 1 diabetes (T1D) and their families to provide optimal family-centered care. Hence, the aim of this study was to explore psychosocial outcomes in young people with T1D and their parents using currently available glucose monitoring devices in a real-life clinic setting.

METHODS

Children and adolescents aged 2-18 years with T1D for more than 6 months and their parents were recruited into a cross-sectional study to complete the Hypoglycemia Fear Survey (HFS) and the Pediatric Quality of Life Inventory (PedsQL) Generic Score Scales, Diabetes Module and Family Impact Module. Demographics and diabetes-specific parameters were obtained from medicals records.

RESULTS

Fifty-nine children and adolescents (mean age 15.1 ± 3.0 years) and 49 parents of children (mean age of children 12.5± 3.3 years) of which 44 were child-parent dyads completed the questionnaires. Parents had a higher mean (SD) FOH total and worry subscore than children, total score was 37.9 (14.6) vs. 32.2 (11.9), p = 0.047 and worry subscore was 17.8 (10.4) vs. 12.8 (9.0), p = 0.01. Furthermore, lower parental diabetes-specific QoL score was observed in parents, 78.8 (12.2) vs. 82.7 (10.3), p=0.02. No difference in FOH and QoL between real-time continuous glucose monitoring (rtCGM) and intermittently scanned glucose monitoring (isCGM) users and users of devices with and without alerts was observed. In isCGM users (n=36 completing the child questionnaires, n=33 completing parent questionnaires), higher parental FOH and lower parental diabetes-specific QoL correlated with higher scanning frequency, r = 0.399, p = 0.021, and r = -0.464, p = 0.007 respectively. No significant correlation was documented between scanning frequency and child questionnaire scores.

CONCLUSIONS

Parents are more likely to perceive higher levels of psychosocial burden related to their child's diabetes than children and adolescents with T1D, especially parents of younger children. This highlights the need for family-based education and treatment resources to support parents in diabetes management in addition to rapidly advancing diabetes technology. In isCGM users, higher parental FOH and lower parent-perceived QoL correlated with a higher scanning frequency, indicating the potential impact of glucose monitoring modality on psychosocial outcomes or vice versa.

Parents' perceptions of quality of life of their children and adolescents with type 1 diabetes during Ramadan fasting in Riyadh

This study aimed to assess parents' perceptions of the quality of life (QoL) of their children with type 1 diabetes (T1D) during Ramadan fasting (RF). In this cross-sectional study, an Arabic-translated version of the standard diabetes-specific QoL questionnaire (PedsQL™ version 3.0) was used to compare perceptions of QoL during Ramadan month (Rm) versus non-Rm (NRm) of parents of children/adolescents with T1D from two tertiary hospitals in Riyadh. We used regression analysis to compare proxies (parents' reports) of their perceptions on their children/adolescents' QoL during Rm compared to NRm. A sample of 61 proxies (parents') of two age groups T1D offspring: 8-12 years (41%) and 13-18 years (59%) who reported their perceptions of their children/adolescents QoL during Rm were matched by children/adolescents' age and gender of 61 proxies in NRm. QoL scores of all domains were significantly lower in Rm compared to NRm; p < 0.0001, however, worries domain showed no statistical differences p = 0.052 in a regression analysis. The total aggregate median (IQR) in Rm was 850 (612-1,062) compared to 1,750 (1,475-2,062) in NRm, p < 0.001. The highest differences in NRm and Rm median scores were observed in communications (OR = 3.64; 95% CI 2.7-5.57) and treatment adherence (OR = 3.09; 95% CI 2.48-3.84) domains especially in the age of 13-18 years. Parents of adolescent boys, who are usually risk-takers and more exposed to outdoor activities, perceived lower QoL for them. Parents of adolescents with T1D perceived a lower QoL for their children during RF, especially in the treatment adherence and communication domains.

A comparison of FreeStyle Libre 2 to self-monitoring of blood glucose in children with type 1 diabetes and sub-optimal glycaemic control: a 12-week randomised controlled trial protocol

Purpose

Frequent glucose monitoring is necessary for optimal glycaemic control. Second-generation intermittently scanned glucose monitoring (isCGM) systems inform users of out-of-target glucose levels and may reduce monitoring burden. We aim to compare FreeStyle Libre 2 (Abbott Diabetes Care, Witney, U.K.) to self-monitoring of blood glucose in children with type 1 diabetes and sub-optimal glycaemic control.

Methods

This open-label randomised controlled trial will enrol 100 children (4–13 years inclusive, diagnosis of type 1 diabetes ≥ 6 months, HbA1c 58–110 mmol/mol [7.5–12.2%]), from 5 New Zealand diabetes centres. Following 2 weeks of blinded sensor wear, children will be randomised 1:1 to control or intervention arms. The intervention (duration 12 weeks) includes second-generation isCGM (FreeStyle Libre 2) and education on using interstitial glucose data to manage diabetes. The control group will continue self-monitoring blood glucose. The primary outcome is the difference in glycaemic control (measured as HbA1c) between groups at 12 weeks. Pre-specified secondary outcomes include change in glucose monitoring frequency, glycaemic control metrics and psychosocial outcomes at 12 weeks as well as isCGM acceptability.

Discussion

This research will investigate the effectiveness of the second-generation isCGM to promote recommended glycaemic control. The results of this trial may have important implications for including this new technology in the management of children with type 1 diabetes.

Trial registration

This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry on 19 February 2020 (ACTRN12620000190909p) and the World Health Organization International Clinical Trials Registry Platform (Universal Trial Number U1111-1237-0090).

Effect of a Hybrid Closed-Loop System on Glycemic and Psychosocial Outcomes in Children and Adolescents With Type 1 Diabetes: A Randomized Clinical Trial

IMPORTANCE

Hybrid closed-loop (HCL) therapy has improved glycemic control in children and adolescents with type 1 diabetes; however, the efficacy of HCL on glycemic and psychosocial outcomes has not yet been established in a long-term randomized clinical trial.

OBJECTIVE

To determine the percentage of time spent in the target glucose range using HCL vs current conventional therapies of continuous subcutaneous insulin infusion or multiple daily insulin injections with or without continuous glucose monitoring (CGM).

DESIGN, SETTING, AND PARTICIPANTS

This 6-month, multicenter, randomized clinical trial included 172 children and adolescents with type 1 diabetes; patients were recruited between April 18, 2017, and October 4, 2019, in Australia. Data were analyzed from July 25, 2020, to February 26, 2021.

INTERVENTIONS

Eligible participants were randomly assigned to either the control group for conventional therapy (continuous subcutaneous insulin infusion or multiple daily insulin injections with or without CGM) or the intervention group for HCL therapy.

MAIN OUTCOMES AND MEASURES

The primary outcome was the percentage of time in range (TIR) within a glucose range of 70 to 180 mg/dL, measured by 3-week masked CGM collected at the end of the study in both groups. Secondary outcomes included CGM metrics for hypoglycemia, hyperglycemia, and glycemic variability and psychosocial measures collected by validated questionnaires.

RESULTS

A total of 135 patients (mean [SD] age, 15.3 [3.1] years; 76 girls [56%]) were included, with 68 randomized to the control group and 67 to the HCL group. Patients had a mean (SD) diabetes duration of 7.7 (4.3) years and mean hemoglobin A1c of 64 (11) mmol/mol, with 110 participants (81%) receiving continuous subcutaneous insulin infusion and 72 (53%) receiving CGM. In the intention-to-treat analyses, TIR increased from a mean (SD) of 53.1% (13.0%) at baseline to 62.5% (12.0%) at the end of the study in the HCL group and from 54.6% (12.5%) to 56.1% (12.2%) in the control group, with a mean adjusted difference between the 2 groups of 6.7% (95% CI, 2.7%-10.8%; P = .002). Hybrid closed-loop therapy also reduced the time that patients spent in a hypoglycemic (<70 mg/dL) range (difference, -1.9%; 95% CI, -2.5% to -1.3%) and improved glycemic variability (coefficient of variation difference, -5.7%; 95% CI, -10.2% to -0.9%). Hybrid closed-loop therapy was associated with improved diabetes-specific quality of life (difference, 4.4 points; 95% CI, 0.4-8.4 points), with no change in diabetes distress. There were no episodes of severe hypoglycemia or diabetic ketoacidosis in either group.

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, 6 months of HCL therapy significantly improved glycemic control and quality of life compared with conventional therapy in children and adolescents with type 1 diabetes.

High Rate of Depression among Saudi Children with Type 1 Diabetes

Saudi Arabia ranks among the top ten in type 1 diabetes (T1D) prevalence. The psychological burden, including depression, among T1D children, affects short-term and long-term outcomes. In Saudi Arabia, studies on depression among T1D children are limited. We determined the prevalence of depression among T1D children and adolescents in the Saudi Arabia-Qassim region and investigated risk factors for depressive symptoms. This quantitative cross-sectional study was conducted among T1D children and adolescents in the outpatient clinic of Maternity and Children Hospital, Buraydah, Saudi Arabia, between October 2020 and April 2021. Using a validated questionnaire translated into Arabic, we interviewed patients during clinic appointment. Questionnaires on sociodemographic characteristics, clinical data, and Clinical Depression Inventory scale were used to measure depression. There were 148 T1D respondents (children: 58.1%; adolescents: 41.9%). More than half were females (53.4%), with most Saudis (94.6%). Depression prevalence among children and adolescents was 27%. Mild, moderate, and severe depression occurred in 80%, 12.5%, and 7.5% of depressed patients, respectively. Factors significant for depression were female sex (p = 0.014), uncontrolled HbA1c level (p = 0.037), and longer diabetes duration (p = 0.013). Depression among children and adolescents was more prevalent in this study than in previous reports. Early detection of depression will improve diabetes control and quality of life.

Psychometric Properties of the Hypoglycemia Fear Survey in a Clinical Sample of Adolescents with Type 1 Diabetes and Their Caregivers

OBJECTIVE

A previously published exploratory factor analysis suggested that the Hypoglycemia Fear Survey-Child and Parent Versions, is comprised of three subscales: Maintain High Blood Glucose, Helplessness/Worry About Low Blood Glucose, and Worry About Negative Social Consequences. The primary aim of this study was to confirm this three-factor model with a clinical population of adolescents with type 1 diabetes (T1D) and their caregivers.

METHODS

Participants included N = 1,035 youth ages 10-17.99 years with T1D, and their female (N = 835) and/or male (N = 326) caregivers who completed the Hypoglycemia Fear Survey independently during a routine medical appointment. We conducted confirmatory factor analysis and examined reliability of the Hypoglycemia Fear Survey and its associations with demographics and clinical outcomes (e.g., mean blood glucose, glycemic control).

RESULTS

Confirmatory factor analysis supported the three-factor model in youth and female and male caregivers. The internal consistencies for Maintain High Blood Glucose, Helplessness/Worry About Low Blood Glucose, and Worry About Negative Social Consequences were acceptable. The majority of demographic and clinical outcome variables correlated as hypothesized with the three subscales.

CONCLUSIONS

Using a large clinical sample of adolescents with T1D and their caretakers, we confirmed the three-factor model for the Hypoglycemia Fear Survey, which is sufficiently reliable to be used in a clinical setting. Important areas of future research include examining moderators for the effect of fear of hypoglycemia on clinical outcomes, and possible inclusion of items related to modern diabetes devices.
