RESUMO
PURPOSE OF REVIEW: This review explores the emerging evidence regarding pathogenesis, future trajectories, treatment options, and phenotypes of youth-onset type 2 diabetes (T2D). RECENT FINDINGS: Youth-onset T2D is increasing in incidence and prevalence worldwide, disproportionately affecting First Nations communities, socioeconomically disadvantaged youth, and people of colour. Youth-onset T2D differs in pathogenesis to later-onset T2D and progresses more rapidly. It is associated with more complications, and these occur earlier. While there are limited licensed treatment options available, the available medications also appear to have a poorer response in youth with T2D. Multiple interacting factors likely contribute to this rising prevalence, as well as the increased severity of the condition, including structural inequities, increasing obesity and sedentary lifestyles, and intergenerational transmission from in-utero exposure to maternal hyperglycemia and obesity. Youth-onset T2D is also associated with stigma and poorer mental health, and these impact clinical management. There is an urgent need to develop effective interventions to prevent youth-onset T2D and enhance engagement of affected youth. It is also critical to better understand the differing phenotypes of youth-onset T2D, to effectively target treatments, and to address intergenerational transmission in high-risk populations.

OBJECTIVE: Youth-onset type 2 diabetes (T2D) is physiologically distinct from adult-onset, but it is not clear how the two diseases differ at a molecular level. In utero exposure to maternal type 2 diabetes (T2D) is known to be a specific risk factor for youth-onset T2D. DNA methylation (DNAm) changes associated with T2D but which differ between youth- and adult-onset might delineate the impacts of T2D development at different ages and could also determine the contribution of exposure to in utero diabetes. METHODS: We performed an epigenome-wide analysis of DNAm on whole blood from 218 youth with T2D and 77 normoglycemic controls from the iCARE (improving renal Complications in Adolescents with type 2 diabetes through REsearch) cohort. Associations were tested using multiple linear regression models while adjusting for maternal diabetes, sex, age, BMI, smoking status, second-hand smoking exposure, cell-type proportions and genetic ancestry. RESULTS: We identified 3830 differentially methylated sites associated with youth T2D onset, of which 3794 were moderately (adjusted p-value < 0.05 and effect size estimate > 0.01) associated and 36 were strongly (adjusted p-value < 0.05 and effect size estimate > 0.05) associated. A total of 3725 of these sites were not previously reported in the EWAS Atlas as associated with T2D, adult obesity or youth obesity. Moreover, three CpGs associated with youth-onset T2D in the PFKFB3 gene were also associated with maternal T2D exposure (FDR < 0.05 and effect size > 0.01). This is the first study to link PFKFB3 and T2D in youth. CONCLUSION: Our findings support that T2D in youth has different impacts on DNAm than adult-onset, and suggests that changes in DNAm could provide an important link between in utero exposure to maternal diabetes and the onset of T2D.

Diabetic kidney disease (DKD) is the main cause of chronic kidney disease (CKD) and progresses faster in males than in females. We identify sex-based differences in kidney metabolism and in the blood metabolome of male and female individuals with diabetes. Primary human proximal tubular epithelial cells (PTECs) from healthy males displayed increased mitochondrial respiration, oxidative stress, apoptosis, and greater injury when exposed to high glucose compared with PTECs from healthy females. Male human PTECs showed increased glucose and glutamine fluxes to the TCA cycle, whereas female human PTECs showed increased pyruvate content. The male human PTEC phenotype was enhanced by dihydrotestosterone and mediated by the transcription factor HNF4A and histone demethylase KDM6A. In mice where sex chromosomes either matched or did not match gonadal sex, male gonadal sex contributed to the kidney metabolism differences between males and females. A blood metabolomics analysis in a cohort of adolescents with or without diabetes showed increased TCA cycle metabolites in males. In a second cohort of adults with diabetes, females without DKD had higher serum pyruvate concentrations than did males with or without DKD. Serum pyruvate concentrations positively correlated with the estimated glomerular filtration rate, a measure of kidney function, and negatively correlated with all-cause mortality in this cohort. In a third cohort of adults with CKD, male sex and diabetes were associated with increased plasma TCA cycle metabolites, which correlated with all-cause mortality. These findings suggest that differences in male and female kidney metabolism may contribute to sex-dependent outcomes in DKD.

Factors affecting intrauterine environment exerts influence on skeletal health and fracture risk in later life. Diabetes during pregnancy is known to influence birth weight and is associated with fetal overgrowth. However, the effects of maternal diabetes on fracture risk in offspring is unknown. This study was aimed to evaluate the association between maternal diabetes and fracture risk in offspring. Using population-based administrative health data for Manitoba, Canada, we identified deliveries complicated by gestational diabetes and type 2 diabetes between April 1, 1980, and March 31, 2020. The cohort was followed for a median of 15.8 yr. The primary outcome was any incident fracture in offspring. Secondary outcomes were long bone upper extremity fracture, long bone lower extremity fracture, vertebral fracture, and any non-trauma fractures. Cox proportional hazard regression models were used to estimate fracture risk in offspring by maternal diabetes status adjusted for relevant covariates. Of the 585 176 deliveries, 26 397 offspring were born to women with diabetes (3.0% gestational diabetes and 1.5% type 2 diabetes), and 558 779 were born to women without diabetes. The adjusted risk for any fracture was 7% (hazard ratio, 1.07; 95% CI, 2.7-11.5%) higher in the offspring of mothers with diabetes than offspring of mothers without diabetes. Types of fractures were similar between the 2 groups with a predominance of long bone upper extremity fractures. In conclusion, maternal diabetes was associated with a modest increase in fracture risk in offspring. Longitudinal prospective studies are needed to understand intrauterine and postnatal factors that may influence fracture risk in the offspring of mothers with diabetes.

INTRODUCTION: Premature onset of type 2 diabetes and excess mortality are critical issues internationally, particularly in Indigenous populations. There is an urgent need for developmentally appropriate and culturally safe models of care. We describe the methods for the codesign, implementation and evaluation of enhanced models of care with Aboriginal and Torres Strait Islander youth living with type 2 diabetes across Northern Australia. METHODS AND ANALYSIS: Our mixed-methods approach is informed by the principles of codesign. Across eight sites in four regions, the project brings together the lived experience of Aboriginal and Torres Strait Islander young people (aged 10-25) with type 2 diabetes, their families and communities, and health professionals providing diabetes care through a structured yet flexible codesign process. Participants will help identify and collaborate in the development of a range of multifaceted improvements to current models of care. These may include addressing needs identified in our formative work such as the development of screening and management guidelines, referral pathways, peer support networks, diabetes information resources and training for health professionals in youth type 2 diabetes management. The codesign process will adopt a range of methods including qualitative interviews, focus group discussions, art-based methods and healthcare systems assessments. A developmental evaluation approach will be used to create and refine the components and principles of enhanced models of care. We anticipate that this codesign study will produce new theoretical insights and practice frameworks, resources and approaches for age-appropriate, culturally safe models of care. ETHICS AND DISSEMINATION: The study design was developed in collaboration with Aboriginal and Torres Strait Islander and non-Indigenous researchers, health professionals and health service managers and has received ethical approval across all sites. A range of outputs will be produced to disseminate findings to participants, other stakeholders and the scholarly community using creative and traditional formats.

OBJECTIVES: Type 2 diabetes (T2D) disproportionately impacts adolescents living in challenging socioeconomic conditions. However, the impacts of T2D on quality of life (QOL) in this context are unknown. Our aim in this study was to evaluate QOL and identify its biological, psychological, and social determinants among adolescents living with and without T2D from similar sociodemographic backgrounds. Relationships between glycemic stability, early complications, and treatments of T2D and QOL were also examined. METHODS: Ninety-two adolescents with T2D and 59 at-risk controls were included from the Improving Renal Complications in Adolescents With Type 2 Diabetes Through Research (iCARE) cohort. The main outcome was QOL (Pediatric QOL Inventory [PedsQL]). Biological covariates included age, sex, body mass index z score, glycated hemoglobin, estimated glomerular filtration rate, and urine albumin-to-creatinine ratio. Psychological factors included perceived stress (14-item Perceived Stress Scale) and mental distress (6-item Kessler scale). Social factors included food security (Household Food Security Survey Module) and income quintile. Multivariate linear regression analyses were used to identify factors associated with QOL between adolescents with and without T2D, and within the T2D cohort. RESULTS: Mean total QOL scores among adolescents with T2D were lower than in controls (67.0±14.8 vs 71.7±16.2, p=0.04). Age, sex, and percent Indigenous ethnicity were not significantly different between groups. Mean duration of T2D was 2.3±2.0 years. In the multivariate analysis, QOL was not associated with diabetes status, but negative associations were seen between mental distress (ß=-1.46, p<0.001) and food insecurity QOL (ß=-6.26, p=0.037). No differences were seen between biological factors and QOL in either analysis. CONCLUSIONS: Significant factors associated with decreased QOL in adolescents living with T2D include mental distress and food insecurity, indicating areas for targeted intervention.

AIM: To describe the incidence and prevalence of type 2 diabetes in children in Manitoba over a ten-year period. METHODS: Population-based, provincial databases were linked to calculate the incidence and prevalence of type 2 diabetes in children < 18 years of age in Manitoba from 2009-10 to 2017-18. First Nation and all other Manitoban children are described separately. RESULTS: The incidence of type 2 diabetes increased from 16.0/100,000/year in 2009-10 to 31â§1/100,000/year in 2017-18 (p < 0.001). For First Nation children, the incidence increased from 73â§4 to 121â§2/100,000/year (p < 0.001). For all other Manitoban children, the incidence increased from 3â§3 to 10â§7/100,000/year (p < 0.001). The prevalence of type 2 diabetes rose from 66â§4 to 124â§2/100,000/year between 2009 -10 and 2017-18 (<0.001). The prevalence in First Nation children rose from 282â§8 to 517â§9/100,000/year (p < 0.001) and in all other Manitoban children from 18â§4 to 35.0/100,000/year (p < 0.001). CONCLUSIONS: The incidence and prevalence of type 2 diabetes is increasing in Manitoban children. While the greatest increase is seen in all other Manitoban children, type 2 diabetes disproportionally affects First Nation children. Understanding the prevalence and incidence of type 2 diabetes in children is necessary for resource allocation and to inform program planning, aimed at both prevention and management.

AIMS: To evaluate associations between 24-h ambulatory blood pressure monitor (ABPM) data vs. single casual blood pressure (BP) and albuminuria in youth with type 2 diabetes. METHODS: A cross-sectional analysis of youth with type 2 diabetes 10-<18 yrs. from the iCARE cohort. MAIN EXPOSURES: daytime HTN (+/- nocturnal), isolated nocturnal HTN and single casual BP. MAIN OUTCOME: non-orthostatic urine albumin: creatinine ratio (ACR) ≥ 3 mg/mmol and log-transformed urine ACR. Regressions evaluated associations between 1. HTN status based on ABPM and log-transformed urine ACR (continuous) and 2. ABPM-derived BP z-scores and casual BPcentiles and albuminuria status (categorical). RESULTS: Of 281 youth included, 19.6 % had daytime HTN (+/- nocturnal), and 28.5 % isolated nocturnal HTN on 24-h ABPM. In multivariate linear regression, HTN (ABPM) (ß = 0.553; p = 0.001), duration of diabetes (ß = 0.857; p = 0.02), HbA1c (ß = 1.172; p ≤0.0001) and ACEI/ARB use (ß = 3.94; p < 0.0001) were positively associated with log-transformed ACR; (R2 = 0.184). In logistic regression analysis, all ABPM LMS z-scores were positively associated with albuminuria; casual BPcentile was not significant. CONCLUSIONS: Youth with type 2 diabetes have high rates of HTN based on 24-ABPM data. ABPM-derived measures of BP are associated with albuminuria. These data support the routine use of ABPM devices to diagnose hypertension in youth with type 2 diabetes.

Gestational diabetes mellitus (GDM) has historically been perceived as a medical complication of pregnancy that also serves as a harbinger of maternal risk of developing type 2 diabetes mellitus (T2DM) in the future. In recent decades, a growing body of evidence has detailed additional lifelong implications that extend beyond T2DM, including an elevated risk of ultimately developing cardiovascular disease. Furthermore, the risk factors that mediate this lifetime cardiovascular risk are evident not only after delivery but are present even before the pregnancy in which GDM is first diagnosed. The concept thus emerging from these data is that the diagnosis of GDM enables the identification of women who are already on an enhanced track of cardiometabolic risk that starts early in life. Studies of the offspring of pregnancies complicated by diabetes now suggest that the earliest underpinnings of this cardiometabolic risk profile may be determined in utero and may first manifest clinically in childhood. Accordingly, from this perspective, GDM is now seen as a chronic metabolic disorder that holds implications across the life span of both mother and child.

BACKGROUND: The aim of the present study was to determine the prevalence of periodontitis in children and adolescents with type 2 diabetes, and if poor glycemic control is associated with increasing prevalence of the disease. METHODS: This is a cross-sectional study involving children and adolescents with type 2 diabetes. A questionnaire related to oral health care history and oral health behaviors was administered to each participant and they then underwent a full-mouth oral evaluation. In addition, clinical and metabolic parameters were extracted from the clinical chart. RESULTS: One hundred and twenty one children and adolescents (8-17 years, 11 months) participated. Overall, 45.5% presented some degree of periodontitis, with 10 (8.3%) mild, 36 (29.8%) moderate, and nine (7.4%) severe. The periodontitis group (PD-group) had higher mean gingival and plaque indexes, periodontal probing depth, and clinical attachment loss than the group without periodontitis (NoPD-group) (p<0.05). A statistically significant relationship between the prevalence of periodontitis and glycosylated hemoglobin (HbA1c) was verified in the bivariate (odds ratio [OR] 1.31 [95% CI, 1.13-1.53], p = 0.001) and multivariate (OR, 1.29 [95% CI, 1.03-1.61], p = 0.03) analysis. For the adjustment variables, associations were verified for duration of diabetes, age, body mass index z-score, lack of running water, insulin use, and acanthosis nigricans. CONCLUSIONS: Children and adolescents with type 2 diabetes presented high rates of periodontitis comparable with that seen in previous studies in youth with diabetes. Uncontrolled HbA1c influences prevalence of periodontal disease. The lack of matched control group and radiographs are limitations of the study. Comprehensive periodontal examination is essential for children and adolescents with type 2 diabetes to prevent, identify, and treat periodontitis early.

Type 2 diabetes is a complex chronic disease rapidly increasing among young people and disproportionately impacting Indigenous youth. Treatment programs are often inadequate for this population as they lack cultural relevance. A scoping review was conducted to explore traditional Indigenous approaches for diabetes prevention and management, to inform a program aimed at supporting Indigenous youth and families with type 2 diabetes. We seek to answer the following question: "Which traditional medicines and practices have been incorporated into intervention or prevention strategies for Indigenous people living with diabetes?" Search was done June 2021 using Ovid Medline, ESBCO and ProQuest databases. Terms included wellbeing, intervention, diabetes, and traditional approaches. Of the 2138 titles screened, 34 met inclusion criteria. Three studies integrated traditional Indigenous approaches into Western-based intervention programming. Content included traditional food and nutrition programs, gardening programs, Elder knowledge sharing, story telling, talking circles, feasting, prayer, traditional dancing, hunting, and school-based wellness curricula. Many were wholistic, co-created with community, Indigenous-led and held in accessible community spaces. The heterogeneity in approaches reflects the diversity of Indigenous nations and communities. This review identifies important elements to include in culturally relevant programs to address diabetes-related wellness.

Objective: Rates of type 2 diabetes (T2D) among adolescents are on the rise. Epigenetic changes could be associated with the metabolic alterations in adolescents with T2D. Methods: We performed a cross sectional integrated analysis of DNA methylation data from peripheral blood mononuclear cells with serum metabolomic data from First Nation adolescents with T2D and controls participating in the Improving Renal Complications in Adolescents with type 2 diabetes through Research (iCARE) cohort study, to explore the molecular changes in adolescents with T2D. Results: Our analysis showed that 43 serum metabolites and 36 differentially methylated regions (DMR) were associated with T2D. Several DMRs were located near the transcriptional start site of genes with established roles in metabolic disease and associated with altered serum metabolites (e.g. glucose, leucine, and gamma-glutamylisoleucine). These included the free fatty acid receptor-1 (FFAR1), upstream transcription factor-2 (USF2), and tumor necrosis factor-related protein-9 (C1QTNF9), among others. Conclusions: We identified DMRs and metabolites that merit further investigation to determine their significance in controlling gene expression and metabolism which could define T2D risk in adolescents.

BACKGROUND: First Nation people living in Canada experience a high prevalence of type 2 diabetes in pregnancy. In this study, we aimed to describe maternal and neonatal outcomes in First Nation and all other females with type 2 diabetes living in Manitoba, Canada. METHODS: This was a population-level retrospective cohort study using linked administrative data from Manitoba (2012-2017). We compared First Nation females with type 2 diabetes with all other Manitoban females with type 2 diabetes, using relative risks (RRs) and 95% confidence intervals (CIs). RESULTS: A total of 2181 females with type 2 diabetes were included, and 1218 (55.8%) were First Nation. First Nation females with type 2 diabetes were significantly more likely to experience stillbirth (RR 2.14, 95% CI 1.11-4.13) and perinatal death (RR 2.39, 95% CI 1.37-4.17) than all other Manitoban females with type 2 diabetes. Offspring of First Nation females with type 2 diabetes had a higher risk of most neonatal complications than offspring of all other Manitoban females with type 2 diabetes, including a higher risk of congenital malformations (RR 1.97, 95% CI 1.30-2.99), but First Nation people did not have a higher risk of most maternal complications. INTERPRETATION: First Nation pregnant individuals living with type 2 diabetes experienced a higher risk for adverse pregnancy outcomes than all other Manitoban females with type 2 diabetes. Additional studies are needed to identify both high-risk and protective factors for pregnancy complications in First Nation people living with type 2 diabetes in pregnancy.

Since the 2018 ISPAD guidelines on this topic, follow-up of large cohorts from around the globe have continued informing the current incidence and prevalence of co-morbidities and complications in young adults with youth-onset type 2 diabetes (T2D). This chapter focuses on the risk factors, diagnosis and presentation of youth-onset T2D, the initial and subsequent management of youth-onset T2D, and management of co-morbidities and complications. We include key updates from the observational phase of the multi-center Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial, the SEARCH for Diabetes in Youth (SEARCH) study and new data from the Restoring Insulin Secretion (RISE) study, a head-to-head comparison of youth onset vs adult-onset T2D. We also include an expanded section on risk factors associated with T2D, algorithms and tables for treatment, management, and assessment of co-morbidities and complications, and sections on recently approved pharmacologic therapies for the treatment of youth-onset T2D, social determinants of health, and settings of care given COVID-19 pandemic.

OBJECTIVE: To describe the prevalence of mental health comorbidity in children with type 2 diabetes compared to a matched population without diabetes and children with type 1 diabetes. RESEARCH DESIGN AND METHODS: Population-based cohorts of 528 youth (7-18 years of age) with prevalent type 2 diabetes, 1519 matched children without diabetes and 778 youth with type 1 diabetes were identified from a clinical registry and linked to provincial health care records to assess the prevalence of mental health comorbidity using ICD-9CM, ICD-10CA and ATC codes. RESULTS: The majority of children with type 2 diabetes were of First Nations heritage. Compared to their matched peers, children with type 2 diabetes where more likely to have a mood or anxiety disorder before and after diagnosis [RR 2.38 (1.63, 3.48) p < 0.001 and 1.70 (1.39, 2.08) p < 0.001 respectively], to attempt/complete suicide [RR 3.18 (1.30, 7.81) p = 0.012 and 2.18 (1.32, 3.60) p = 0.0002 respectively] and be prescribed an antipsychotic [RR 2.33 (1.23, 4.39) p = 0.009 and 1.76 (1.23, 2.52) p = 0.002 respectively]. Following adjustment for age and sex, children with type 2 diabetes, compared to children with type 1 diabetes where more likely to have a mood or anxiety disorder and be prescribed an antipsychotic after diagnosis [RR 1.43 (1.07, 1.91) p = 0.015; RR 2.41 (1.44, 4.06) p = 0.0009 respectively]. CONCLUSIONS: Children with type 2 diabetes have high rates of comorbid mental illness. Programs to provide care, support, and education must address the mental health comorbidity in the context of the demographic, socioeconomic, and psycho-cultural characteristics of the population.

OBJECTIVE: To describe hospitalization rates and reasons for hospitalization in children with type 2 diabetes (T2D) and to compare these rates to a matched cohort without diabetes and to children with type 1 diabetes (T1D). METHODS: Population-based cohorts of 528 children (7-18 years of age) with prevalent T2D, 1519 matched control children without diabetes and 778 children with T1D were identified from a clinical registry and linked to health care records to assess hospitalizations and reasons for hospitalizations using ICD-9CM and ICD-10CA codes. RESULTS: Children with T2D are more likely than their matched controls and children with T1D to be admitted to hospital in the year prior to diagnosis {RR 2.83 (1.77, 4.53) p < 0.0001 and 8.05 (4.05, 16.00) p < 0.0001, respectively}, in the first year post diagnosis {RR 3.19 (2.08, 4.89) p < 0.0001 and 3.04 (1.86, 4.98) p < 0.0001, respectively} and in the 5 year post diagnosis period {RR 1.99 (1.56, 2.53) p < 0.0001 and 1.91 (1.48, 2.46) p < 0.0001, respectively}. Mental illness was the most common cause for hospital admission in both children with T2D and their matched controls. CONCLUSIONS: This differs from children with T1D where endocrine causes constitute the most common reason for hospital admission. This analysis provides novel data on hospitalization rates and diagnoses in the increasing population of children with T2D. This information is important to inform health care programming and health policy planning to best meet the needs of this population.

AIMS: Interleukin-9 (IL-9) attenuates podocyte injury in experimental kidney disease, but its role in diabetic nephropathy is unknown. We sought to relate urinary IL-9 levels to the release of podocyte-derived extracellular vesicles (EVs) in youth with type 1 diabetes. We related urinary IL-9 levels to clinical variables and studied interactions between urinary IL-9, vascular endothelial growth factor (VEGF), tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6) on urinary albumin/creatinine ratio (ACR) a functional measure of podocyte injury. METHODS: We performed an analysis of urine samples and clinical data from a cohort of youth with type 1 diabetes (n = 53). Cytokines were measured using a Luminex platform (Eve Technologies), and nanoscale flow cytometry was employed to quantify urinary podocyte-derived EVs. All urinary measures were normalized to urinary creatinine. RESULTS: Mean age was 14.7 ± 1.6 years, and the mean time from diagnosis was 6.7 ± 2.9 years. Mean HbA1c was 70.3 ± 13.9 mmol/mol, mean ACR was 1.3 ± 1.9 mg/mmol, and mean eGFR was 140.3 ± 32.6 ml/min/1.73 m2. IL-9 was inversely related to podocyte EVs (r = - 0.56, p = 0.003). IL-9 was also inversely related to blood glucose, HbA1C and eGFR (r = - 0.44, p = 0.002; r = - 0.41, p = 0.003; r = - 0.49, p < 0.001, respectively) and positively correlated with systolic BP (r = 0.30, p = 0.04). There was a significant interaction between IL-9, EVs and ACR (p = 0.0143), and the relationship between IL-9 and ACR depended on VEGF (p = 0.0083), TNFα (p = 0.0231) and IL-6 levels (p = 0.0178). CONCLUSIONS: IL-9 is associated with podocyte injury in early type 1 diabetes, and there are complex interactions between urinary IL-9, inflammatory cytokines and ACR.

OBJECTIVES: The aim of this study was to assess the impacts of the COVID-19 pandemic on adolescents and young adults living with type 2 diabetes (T2D) involved in the national Improving Renal Complications in Adolescents with T2D through REsearch (iCARE) study. METHODS: The Environmental influences on Child Health Outcomes (ECHO) COVID-19 Questionnaire developed by the National Institutes of Health ECHO COVID-19 Task Force was administered to participants (n=85) from the iCARE study between June 2020 and October 2020. Children 12 years old (via parent report) and adolescents and young adults ≥13 years old (via self-report) participated. The questionnaire assessed the impact of the pandemic on health-care appointments, lifestyle, internet use, social connections and mental health. RESULTS: Participants were 17.0±3.1 (range, 12 to 27) years of age and predominantly female (61.3%). During the pandemic, 69.4% were able to attend their health-care appointments by telephone or virtual platforms, 31.7% ate more, 45.1% slept more and 29.3% spent less time on physical activities. There was an increase in internet use for both educational (42.0%) and noneducational purposes (54.9%). Participants felt less socially connected (64.6%). Participants also felt sometimes (59.2%), often (19.7%) and very often (6.7%) satisfied with their lives. DISCUSSION: Our study revealed that the COVID-19 pandemic has had various impacts on the daily lives of adolescents and young adults living with T2D. Future research should include longitudinal studies of the health burden of the COVID-19 pandemic on this population, with a more in-depth evaluation of mental health outcomes and clinical outcomes.

OBJECTIVE: Our aim in this study was to determine the best administrative data case definition for pregestational diabetes exposure. METHODS: We compared the performance of case definitions for pregestational diabetes exposure within the administrative health data housed in the Manitoba Population Health Research Repository at the Manitoba Centre for Health Policy with an identified population of women in whom the diagnosis of pregestational diabetes was known from the clinical database of the Manitoba Diabetes Education Resource for Children and Adolescents (DER-CA) (August 12, 1989 through January 28, 2015). The DER-CA database contains maternal diabetes status during pregnancy and also includes women diagnosed with type 2 diabetes in childhood whose pregnancies were thus all complicated by pregestational diabetes exposure. Linkage of mother-child dyads is possible within the Repository. Diagnosis codes from the International Classification of Diseases---ninth or tenth revision and physician tariff codes were used to identify diabetes in the biologic mothers of children with type 2 diabetes identified from the DER-CA database. The timing of the diagnosis of diabetes in the mother with respect to the gestational age of the pregnancy was determined. RESULTS: The best administrative definition of pregestational diabetes exposure was any incident code for diabetes in the mother before the pregnancy of the index child or within the first 25 weeks of pregnancy (sensitivity: 84.77%; positive predictive value: 92%). CONCLUSION: The definition cited can be used to define pregestational diabetes exposure in studies utilizing administrative data.
