RESUMO
Given the proven benefits of screening to reduce diabetic ketoacidosis (DKA) likelihood at the time of stage 3 type 1 diabetes diagnosis, and emerging availability of therapy to delay disease progression, type 1 diabetes screening programmes are being increasingly emphasised. Once broadly implemented, screening initiatives will identify significant numbers of islet autoantibody-positive (IAb+) children and adults who are at risk of (confirmed single IAb+) or living with (multiple IAb+) early-stage (stage 1 and stage 2) type 1 diabetes. These individuals will need monitoring for disease progression; much of this care will happen in non-specialised settings. To inform this monitoring, JDRF in conjunction with international experts and societies developed consensus guidance. Broad advice from this guidance includes the following: (1) partnerships should be fostered between endocrinologists and primary-care providers to care for people who are IAb+; (2) when people who are IAb+ are initially identified there is a need for confirmation using a second sample; (3) single IAb+ individuals are at lower risk of progression than multiple IAb+ individuals; (4) individuals with early-stage type 1 diabetes should have periodic medical monitoring, including regular assessments of glucose levels, regular education about symptoms of diabetes and DKA, and psychosocial support; (5) interested people with stage 2 type 1 diabetes should be offered trial participation or approved therapies; and (6) all health professionals involved in monitoring and care of individuals with type 1 diabetes have a responsibility to provide education. The guidance also emphasises significant unmet needs for further research on early-stage type 1 diabetes to increase the rigour of future recommendations and inform clinical care.
RESUMO
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.

PURPOSE OF REVIEW: Although pervasive inequities in the health outcomes of youth and young adults with type 1 diabetes (T1D) exist, the role of provider bias in these inequities is not well-understood. The purpose of this review is to synthesize evidence from existing studies on the associations between patient characteristics, provider bias, and patient health. RECENT FINDINGS: Fourteen articles were included. Determining the extent of the effects of provider bias on patient health is limited by a lack of consensus on its definition. Experiences of provider bias (e.g., shaming, criticism) negatively affects self-esteem, relationships with medical providers, and depressive symptoms. Provider bias also impacts diabetes technology recommendations, insulin regimen intensity, and risk for life-threatening T1D complications. Future studies are needed to develop questionnaires and interviews that better account for diverse experiences and interpretations of bias in T1D healthcare. More research is also needed to investigate mitigating factors to reduce provider bias as a way to improve psychological and physical health in individuals with T1D.

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.

OBJECTIVE: To develop a reliable and valid short form of the State Anxiety Subscale of the State-Trait Anxiety Inventory for Children (STAI-CH) in the Environmental Determinants of Diabetes in the Young (TEDDY) study. METHODS: A Development Sample of 842 10-year-old TEDDY children completed the STAI-CH State Subscale about their type 1 diabetes (T1D) risk. The best 6 items (three anxiety-present and three anxiety-absent) for use in a short form (SAI-CH-6) were identified via item-total correlations. SAI-CH-6 reliability was examined in a Validation Sample (n = 257) of children who completed the full 20-item STAI-CH State Subscale and then again in an Application Sample (n = 2,710) who completed only the SAI-CH-6. Expected associations between the children's SAI-CH-6 scores and country of residence, sex, T1D family history, accuracy of T1D risk perception, worry about getting T1D, and their parents' anxiety scores were examined. RESULTS: The SAI-CH-6 was reliable (α = 0.81-0.87) and highly correlated with the full 20-item STAI-CH State Subscale (Development Sample: r = 0.94; Validation Sample: r = 0.92). SAI-CH-6 scores detected significant differences in state anxiety symptoms associated with T1D risk by country, T1D family history, accuracy of T1D risk perception, and worry about getting T1D and were correlated with the child's parent's anxiety. CONCLUSION: The SAI-CH-6 appears useful for assessing children's state anxiety symptoms when burden and time limitations prohibit the use of the STAI-CH. The utility of the SAI-CH-6 in older children with and without chronic conditions needs to be assessed.

OBJECTIVE: To examine the association of physical activity (PA), measured by accelerometry, to hemoglobin AIC (HbA1c) and oral glucose tolerance test (OGTT) outcomes in children who were multiple persistent confirmed autoantibody positive for type 1 diabetes (T1D). METHODS: The Environmental Determinants of Diabetes in the Young (TEDDY) multinational study followed children from birth. Children ≥3 years of age who were multiple persistent confirmed autoantibody positive were monitored by OGTTs every 6 months. TEDDY children's PA was measured by accelerometry beginning at 5 years of age. We examined the relationship between moderate plus vigorous (mod + vig) PA, HbA1c, and OGTT in 209 multiple autoantibody children who had both OGTT and PA measurements. RESULTS: Mod + vig PA was associated with both glucose and C-peptide measures (fasting, 120-min, and AUC); higher mod + vig PA was associated with a better OGTT response primarily in children with longer duration of multiple autoantibody positivity. Mod + vig PA also interacted with child age; lower mod + vig PA was associated with a greater increase in C-peptide response across age. Mod + vig PA was not related to fasting insulin, HOMA-IR or HbA1c. CONCLUSIONS: The OGTT is the gold standard for diabetes diagnosis and is used to monitor those at high risk for T1D. We found higher levels of mod + vig PA were associated with better OGTT outcomes in children ≥5 years of age who have been multiple autoantibody positive for longer periods of time. Physical activity should be the focus of future efforts to better understand the determinants of disease progression in high-risk children.

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.

Background: Little is known about the coronavirus disease 2019 (COVID-19) pandemic's psychological effects on caregivers of children with type 1 diabetes. Objective: This study aimed to investigate the experience of caregivers of youth with type 1 diabetes during the COVID-19 pandemic. Methods: A 49-item questionnaire using a 5-point Likert scale and open-response questions was distributed via e-mail and type 1 diabetes-related social media platforms from 4 May to 22 June 2020. Quantitative data were analyzed using SPSS v.25 statistical software. Descriptive statistics were used. Relationships were compared using Pearson correlation. Qualitative data were coded and categorized. Results: A total of 272 caregivers participated (mean ± SD respondent age 42.1 ± 7.8 years; 94.5% females; 81.3% with college degree or higher; 52.6% with annual income >$99,000; 80.1% with private insurance). The mean ± SD age of caregivers' children with type 1 diabetes was 11.0 ± 4.1 years, and their mean ± SD diabetes duration was 4.2 ± 3.5 years. Participants reported being diagnosed with or knowing someone with COVID-19 (24.6%), increased stress (71.9%), job loss (10.3%), and financial difficulty (26.8%) as a result of the pandemic. General self-efficacy scores were high (mean ± SD 16.2 ± 2.6, range 8-20) and significantly correlated with COVID-19-related self-efficacy (mean ± SD 12.6 ± 2.1; R = 0.394, P <0.001) and type 1 diabetes self-efficacy during COVID-19 (mean ± SD 17.1 ± 2.5; R = 0.421, P <0.001). Conclusion: Despite reporting high overall self-efficacy, caregivers of children with type 1 diabetes reported greater overall stress and challenges during the pandemic. Health care providers should be prepared to provide families with specific social and mental health support.
RESUMO
PURPOSE: Youth with type 1 diabetes (T1D) often use Continuous Glucose Monitoring (CGM) devices; however, many do not wear them consistently enough to obtain optimal glycemic benefit. This study aimed to identify demographic and psychosocial predictors of optimal CGM use in adolescents with T1D to inform nurse-led interventions to improve adherence. DESIGN AND METHODS: Cross-sectional survey data from youth (12-19 years) using CGM were analyzed to determine whether perceived benefits/burdens of CGM, self-efficacy, and coping predicted being a "CGM Optimizer" (wearing CGM 6-7 days/week) or "CGM Sub-user." RESULTS: Of 282 adolescents (54% female), 161 were CGM Optimizers and 121 were CGM Sub-Users. Optimizers were younger (15.91 ± 2.17 years vs. 16.79 ± 2.17, p = 0.001), more likely non-Hispanic White (91.9% vs 83.5%, p = 0.029), and more likely to have private insurance (82.0% vs. 69.4%, p = 0.009). Every 1-point increase on Benefits of CGM scale was associated with 2.8 times greater odds of being an Optimizer (OR = 2.82, 95% CI 1.548-5.132, p = 0.001), and every 1-point increase on the Burdens of CGM scale was associated with a 52% decrease in odds (OR = 0.48, 95% CI = 0.283-0.800, p = 0.005), with final logistic regression model (including only these two predictors) explaining 22.3% of variance. CONCLUSION: CGM Optimizing adolescents were more likely to perceive higher benefit and lower burden of CGM. PRACTICAL IMPLICATIONS: Nurse-led interventions to promote benefits of CGM and mitigate burden may help youth increase adherence with CGM to achieve glycemic benefit.

Type 1 diabetes (T1D) is a lifelong and chronic condition that can cause severely compromised health. The T1D treatment regimen is complex, and is a particular challenge for adolescents, who frequently experience a number of treatment adherence barriers (e.g., forgetfulness, planning and organizational challenges, stress). Diabetes Journey is a gamified mHealth program designed to improve T1D self-management through a specific focus on decreasing adherence barriers and improving executive functioning skills for adolescents. Grounded in situativity theory and guided by a sociotechnical-pedagogical usability framework, Diabetes Journey was designed, developed, and evaluated using a learning experience design approach. This approach applied design thinking methods within a Successive Approximation Model design process. Iterative design and formative evaluation were conducted across three design phases, and improvements were implemented following each phase. Findings from the user testing phase indicate Diabetes Journey is a user-friendly mHealth program with high usability that holds promise for enhancing adolescents' T1D self-management. Implications for future designers and researchers are discussed regarding the social dimension of the sociotechnical-pedagogical usability framework. An extension to the framework is proposed to extend the social dimension to include socio-cultural and contextual considerations when designing mHealth applications. Consideration of the pedagogical and sociocultural dimensions of learning is imperative when developing psychoeducational interventions.
RESUMO
PURPOSE OF REVIEW: Understanding barriers to self-management behaviors and glycemic stability may inform specific needs for behavior change in adolescents and young adults with type 1 diabetes (T1D). The current review aims to systematically synthesize the literature on the relationships between executive functioning, self-management, and A1C in adolescents and young adults with T1D. Fifteen studies were retained in the current review. Study quality assessment for the majority of the studies were "Fair" or "Good." RECENT FINDINGS: This review highlights several advances in research design, including use of longitudinal designs, data from multiple informants, and use of objective measures. Adolescents and young adults reported that more executive functioning weaknesses were related to decreased self-management behaviors and higher A1C. The current review demonstrated that self-perceived executive functioning weaknesses negatively impact self-management behaviors and A1C. Future research is needed to determine the utility of objective measures in assessing the relationships between executive functioning, T1D self-management, and A1C.

AIM: To describe real-world hybrid closed loop (HCL) use and glycaemic outcomes across the lifespan and identify a clinical threshold for HCL use associated with meeting the internationally recommended target of 70% sensor glucose time in range (TIR; 70-180 mg/dL). MATERIALS AND METHODS: Mixed models examined MiniMed 670G HCL use and glycaemic outcomes in 276 people with type 1 diabetes from four age groups: youth (aged <18 years), young adults (18-25 years), adults (26-49 years) and older adults (≥50 years) for 1 year. ROC analysis identified the minimum percentage HCL use associated with meeting the TIR goal of 70%. RESULTS: HCL use at month 1 was 70.7% ± 2.9% for youth, 71.0% ± 3.8% for young adults, 78.9% ± 2.1% for adults and 84.7% ± 3.8% in older adults. HCL use declined significantly at 12 months to 49.3% ± 3.2% in youth (P < .001) and 55.7% ± 4.3% in young adults (P = .002). HCL use was sustained at 12 months in adults (76.4% ± 2.2%, P = .36) and older adults (80.4% ± 3.9%, P = .36). HCL use of 70.6% was associated with 70% TIR (sensitivity 58.3%, specificity 85%, AUC 0.77). Older age, 80% or higher continuous glucose monitor use and four or more blood glucose checks per day were associated with attaining the HCL-use threshold. CONCLUSIONS: HCL use of 70% or higher may be a useful target for clinicians to use to assist people with diabetes in attaining glycaemic goals. Youth may struggle with HCL use more than adults and require clinical intervention to help sustain HCL use across time.

OBJECTIVE: We examined parental diabetes monitoring behaviors in a cohort of children at increased genetic risk for type 1 diabetes. We hypothesized that being informed of a positive islet autoantibody (IA) would increase monitoring behaviors. RESEARCH DESIGN AND METHODS: The Environmental Determinants of Diabetes in the Young (TEDDY) study follows 8676 children with high-risk human leucocyte antigen-DQ genotypes from birth to age 15, including general population (GP) children and those with a first-degree relative (FDR) with diabetes. Data on parental monitoring behaviors were solicited yearly. Serum samples were tested for IA and parents were informed of child results. We examined parental monitoring behaviors during the first 7 years of TEDDY. RESULTS: In IA- children, the most common monitoring behavior was participating in TEDDY study tasks; up to 49.8% and 44.2% of mothers and fathers, respectively, reported this. Among FDRs, 7%-10% reported watching for diabetes symptoms and 7%-9% reported monitoring the child's glucose, for mothers and fathers, respectively. After IA+ notification, all monitoring behaviors significantly increased in GP parents; only glucose monitoring increased in FDR parents and these behaviors continued for up to 4 years. FDR status, accurate diabetes risk perception, and anxiety were associated with glucose monitoring in IA+ and IA- cohorts. CONCLUSIONS: Many parents view TEDDY participation as a way to monitor for type 1 diabetes, a benefit of enrollment in a longitudinal study with no prevention offered. IA+ notification increases short- and long-term monitoring behaviors. For IA- and IA+ children, FDR parents engage in glucose monitoring, even when not instructed to do so.

OBJECTIVE: To examine adherence to the oral glucose tolerance test (OGTT) in multiple islet autoantibody children in stage 1 of developing type 1 diabetes (T1D). METHODS: Children are followed from birth in The Environmental Determinants of Diabetes in the Young (TEDDY) study. Completion of an OGTT is recommended every 6 months in children ≥3 years of age who are multiple islet autoantibody positive. Factors associated with adherence to the OGTT protocol were examined. RESULTS: The average subject level adherence with the OGTT protocol was 62% although there were large differences across countries; Finnish participants and older children from Sweden were more adherent than participants from the United States and Germany. Factors associated with nonadherence included having a first-degree relative with T1D, using a local laboratory rather than a TEDDY center for the OGTT, and maternal underestimation of the child's risk for T1D. Children were more adherent to the OGTT if their mothers: were more satisfied with TEDDY participation, reported monitoring the child for T1D by checking blood glucose levels at home, and viewed participating in TEDDY as the primary way they were monitoring the child for T1D. CONCLUSIONS: In a study of children in stage 1 of T1D, adherence to an OGTT protocol was suboptimal despite extensive efforts to communicate the child's high risk to parents. These findings provide important guidance for development of strategies to improve methods for detecting progression or the development of T1D in high-risk pediatric populations.

PURPOSE OF REVIEW: Due to treatment advancements, individuals with type 1 diabetes (T1D) are living longer, presenting a unique understudied population with advanced complex needs. This article is a review of the aging literature in T1D and identifies existing gaps while serving as a call to the research community. RECENT FINDINGS: Recent studies have identified an association between cognitive impairment and glycemic variability, as well as increased risk and frequency of hypoglycemia in older adults with T1D. However, limited research exists about additional physical and mental health conditions and barrier to successful treatment in this population. Older adults may experience both age- and diabetes-related barriers to diabetes management. Due to the scarcity of aging T1D research, current treatment guidelines for this age group are based on type 2 diabetes research. There is a critical need to further investigate the physical and mental effects of T1D and aging as well as public health policy; insurance challenges; and needs for support and interventions for older adults with T1D.

OBJECTIVE: To describe predictors of hybrid closed loop (HCL) discontinuation and perceived barriers to use in youth with type 1 diabetes. SUBJECTS: Youth with type 1 diabetes (eligible age 2-25 y; recruited age 8-25 y) who initiated the Minimed 670G HCL system were followed prospectively for 6 mo in an observational study. RESEARCH DESIGN AND METHODS: Demographic, glycemic (time-in-range, HbA1c), and psychosocial variables [Hypoglycemia Fear Survey (HFS); Problem Areas in Diabetes (PAID)] were collected for all participants. Participants who discontinued HCL (<10% HCL use at clinical visit) completed a questionnaire on perceived barriers to HCL use. RESULTS: Ninety-two youth (15.7 ± 3.6 y, HbA1c 8.8 ± 1.3%, 50% female) initiated HCL, and 28 (30%) discontinued HCL, with the majority (64%) discontinuing between 3 and 6 mo after HCL start. Baseline HbA1c predicted discontinuation (P = .026) with the odds of discontinuing 2.7 times higher (95% CI: 1.123, 6.283) for each 1% increase in baseline HbA1c. Youth who discontinued HCL rated difficulty with calibrations, number of alarms, and too much time needed to make the system work as the most problematic aspects of HCL. Qualitatively derived themes included technological difficulties (error alerts, not working correctly), too much work (calibrations, fingersticks), alarms, disappointment in glycemic control, and expense (cited by parents). CONCLUSIONS: Youth with higher HbA1c are at greater risk for discontinuing HCL than youth with lower HbA1c, and should be the target of new interventions to support device use. The primary reasons for discontinuing HCL relate to the workload required to use HCL.

OBJECTIVE: To describe glycemic and psychosocial outcomes in youth with type 1 diabetes using a hybrid closed loop (HCL) system. SUBJECTS: Youth with type 1 diabetes (2-25 years) starting the 670G HCL system for their diabetes care were enrolled in an observational study. METHODS: Prospective data collection occurred during routine clinical care and included glycemic variables (sensor time in range [70-180 mg/dL], HbA1c), and psychosocial variables (Hypoglycemia Fear Survey [HFS]; Problem Areas in Diabetes [PAID]). Mixed models were used to analyze change across time. RESULTS: Ninety-two youth (mean age 15.7 ± 3.6 years, 50% female, HbA1c 8.8% ± 1.8%) started HCL for their diabetes care. Youth used Auto Mode 65.5% ± 3.0% of the time at month 1, which decreased to 51.2% ± 3.4% at month 6 (P = .001). Sensor time in range increased from 50.7% ± 1.8% at baseline to 56.9% ± 2.1% at 6 months (P = .007). HbA1c decreased from 8.7% ± 0.2% at baseline to 8.4% ± 0.2% after 6 months of use (P ≤ .0001), with the greatest HbA1c decline in participants with high baseline HbA1c. Increased percent time in auto mode was associated with lower HbA1c (P = .02). Thirty percent of youth discontinued HCL in the first 6 months of use. There were no changes in the HFS or PAID scores across time. CONCLUSIONS: HCL use is associated with improved glycemic control and no change in psychosocial outcomes in this clinical sample. The decline in HCL use across time suggests that youth experience barriers in sustaining use of HCL. Further research is needed to understand reasons for HCL discontinuation and determine intervention strategies.

Hypoglycemia is a common and dangerous complication of type 1 diabetes (T1D). Although some worry about hypoglycemia is adaptive, some individuals develop severe and impairing anxiety symptoms about hypoglycemic episodes. This presentation, known as severe fear of hypoglycemia (FOH), is similar to a specific phobia, and becomes problematic when it interferes with one's quality of life or T1D management. Although FOH is common, there have not yet been any treatment studies to address severe and impairing levels of FOH in the T1D population. The purpose of the following case report is to: (a) describe the presentation of a severe case of FOH in a young adult with T1D; (b) demonstrate the effectiveness of graduated exposure therapy for treatment of severe FOH; and (c) provide implications for clinical practice. A previously developed conceptual model for FOH management guided treatment. Treatment using graduated exposure therapy for FOH resulted in reduced worry about low blood glucose (BG) and significant reduction in behaviors to maintain high BG levels. Assessment of FOH and the risk and benefits of using a continuous glucose monitor among individuals with T1D and their families are discussed.

OBJECTIVE: To determine autism spectrum disorder (ASD) prevalence within our pediatric type 1 diabetes (T1D) clinic population and determine clinical characteristics and technology used by individuals with both ASD and T1D compared to matched controls with T1D alone and compared to our overall pediatric T1D clinic. METHODS: Medical chart review showed 30 individuals with both ASD and type 1 diabetes (ASD + T1D). Controls (n = 90) were matched for age, sex, race/ethnicity, and T1D duration. ASD + T1D was compared to both matched controls and the pediatric T1D clinical population. RESULTS: ASD prevalence in the pediatric T1D population was 1.16% (CI 0.96-1.26). Compared to the T1D clinic, ASD + T1D had more males (93% vs 52%; P < 0.0001), lower hemoglobin A1c (HbA1c) (8.2% vs 8.9%; 66 vs 74 mmol/mol; P = 0.006), and lower insulin pump (CSII) use (37% vs 56%; P < 0.0001). No differences were found between ASD + T1D and matched controls in HbA1c or blood glucose checks per day. The ASD + T1D group was less likely to use CSII than matched controls (37% vs 61%; P = 0.03). HbA1c did not change after CSII initiation in ASD + T1D, but increased for matched controls. CONCLUSIONS: Prevalence of ASD in the pediatric T1D population is comparable to the general population in Colorado. Individuals with ASD may experience barriers limiting CSII use, but achieve equivalent glycemic control compared to those without ASD. CSII may be more effective in maintaining lower HbA1c over time in those with ASD than in those without ASD.

OBJECTIVE: To examine the prevalence and correlates of non-severe hypoglycemia among adolescents with type 1 diabetes and suboptimal glycemic control, an understudied topic in this group. METHODS: Seven days of blinded continuous glucose monitor data were analyzed in 233 adolescents at baseline of the Flexible Lifestyle Empowering Change trial (13-16 years, type 1 diabetes duration >1 year, and hemoglobin A1c [HbA1c] 8-13% [64-119 mmol]). Incidence of clinical hypoglycemia (54-69 mg/dL) and clinically serious hypoglycemia (<54 mg/dL) was defined as number of episodes ≥15 minutes. Logistic regression modeling was used to determine the correlates of long duration of hypoglycemia, categorized by median split among those who experienced hypoglycemia. RESULTS: The sample was 76.1% non-Hispanic white, 49.8% female, age = 14.9 ± 1.1 years, diabetes duration = 6.4 ± 3.7 years, and HbA1c = 9.6 ± 1.2% (81 ± 13 mmol/mol). Over 7 days, 79.4% of youth experienced ≥1 hypoglycemic episodes of <70 mg/dL, and 55.4% of youth experienced ≥1 hypoglycemic episodes of <54 mg/dL. Among all adolescents, the median duration of clinical hypoglycemia and clinically serious hypoglycemia was 21.9 (range 0-250.2) and 4.3 (range 0-209.7) minutes/day, respectively. Long duration of clinical hypoglycemia (range 1.8-17.4% time overall) and clinically serious hypoglycemia (range 1.2-14.6% time overall) was associated with older age and decreasing HbA1c. Long duration of clinically serious hypoglycemia also was associated with insulin pump use. CONCLUSIONS: Almost 80% of adolescents with elevated HbA1c had an episode of clinical hypoglycemia, and >50% had clinically serious hypoglycemia in a week. Increased education alongside access to emerging diabetes technologies may help to prevent hypoglycemia while improving glycemic control.
