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.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.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) (p0.05). 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.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.

Background: 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. 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 health care records to assess the prevalence of mental health comorbidity using ICD-9CM, ICD-10CA and ATC codes. Findings: 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

Background: The First Nations Community Based Screening to Improve Kidney Health and Prevent Dialysis project was a point-of-care screening program in rural and remote First Nations communities in Manitoba that aimed to identify and treat hypertension, diabetes and chronic kidney disease. The program identified chronic disease in 20% of children screened. We aimed to characterize clinical screening practices before and after intervention in children aged 10–17 years old and compare outcomes with those who did not receive the intervention. Methods: This observational, prospective cohort study started with community engagement and followed the principles of ownership, control, access and possession (OCAP). We linked participant data to administrative data at the Manitoba Centre for Health Policy to assess rates of primary care and nephrology visits, disease-modifying medication prescriptions and laboratory testing (i.e., glycosylated hemoglobin [HbA1c], estimated glomerural filtration rate [eGFR] and urine albumin- or protein-to-creatinine ratio). We analyzed the differences in proportions in the 18 months before and after the intervention. We also conducted a 1:2 propensity score matching analysis to compare outcomes of children who were screened with those who were not. Results: We included 324 of 353 children from the screening program (43.8% male; median age 12.3 yr) in this study. After the intervention, laboratory testing increased by 5.8% (95% confidence interval [CI] 1.1% to 10.1%) for HbA1c, by 9.9% (95% CI 4.2% to 15.5%) for eGFR and by 6.2% (95% CI 2.3% to 10.0%) for the urine albumin- or protein-to-creatinine ratio. We observed significant improvements in laboratory testing in screened patients in the group who were part of the program, compared with matched controls. Interpretation: Chronic disease surveillance and care increased significantly in children after the implementation of a point-of-care screening program in rural and remote First Nation communities. Interventions such as active surveillance programs have the potential to improve the chronic disease care being provided to First Nations children.

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.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).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.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.

OBJECTIVES In this study, we aimed to compare health-care visits pre- and posttransition from pediatric to adult care between youth with type 2 and type 1 diabetes. METHODS We linked a clinical database with the Manitoba Population Research Data Repository to compare health-care visits 2 years before and after transition, and investigated baseline factors influencing health-care engagement. RESULTS Youth with type 2 diabetes (n=196) vs type 1 diabetes (n=456) were more likely to be female (61% vs 44%), older at diagnosis (13.6 vs 10.6 years), live in northern regions and to be in the lowest socioeconomic status quartile (53% vs 5.4%). Seventy-six percent of youth with type 2 diabetes attended a follow-up visit within 2 years of transition compared to 97% of youth with type 1 diabetes. Youth with type 2 diabetes had higher rates of hospitalization pretransition (19.6 vs 11.6 admissions/100 patient years) and posttransition (24.7 vs 11.7 admissions/100 patient years) and fewer medical visits (pretransition: 2.4 vs 3.0 visits/person year [p

Objectives Little is known about the relationship between albuminuria in youth with type 2 diabetes (T2D) and cardiovascular risk. We aimed to determine whether youth with T2D and albuminuria have evidence of increased cardiovascular risk and/or early cardiovascular dysfunction compared with youth with T2D without albuminuria. Methods Youth with T2D were stratified by albuminuria status. Cardiovascular risk factors, including body mass index (BMI), 24-hour blood pressure, lipid profile, smoking and smoking exposure, habitual physical activity and screen time, were compared between groups. Left ventricular structure and function and carotid intima-media thickness (cIMT) were evaluated in participants who underwent cardiac imaging. Results Two hundred sixty-five youth participated, 83 (31.3%) of whom had albuminuria. Ethnicity, sex, BMI z score, age at diagnosis, duration of diabetes and hepatocyte nuclear factor-1alpha status did not differ between youth stratified by albuminuria. Smoking, exposure to second-hand smoke and low physical activity levels did not differ between groups. Youth with albuminuria were more likely to have hypertension, dyslipidemia and poor glycemic control. Left ventricular structure and carotid cIMT did not differ between groups, but youth with albuminuria had evidence of early left ventricular diastolic dysfunction. Conclusions We found evidence of increased cardiovascular disease risk factors and left ventricular diastolic dysfunction in youth with T2D and albuminuria compared with those without albuminuria, despite a relatively short duration of disease. Thus, albuminuria may serve as a marker of early cardiovascular disease risk in youth with T2D.

BACKGROUND: Despite prevention efforts, type 2 diabetes mellitus continues to increase in incidence among First Nations children and is associated with early and aggressive complications. We aimed to determine the experiences of adolescents living with type 2 diabetes and the barriers to living well with type 2 diabetes that adolescents perceived. METHODS: We recruited adolescents with type 2 diabetes mellitus from the pediatric diabetes clinic in Winnipeg, Manitoba, to participate in a day-long facilitated focus group discussion. Group discussions were recorded and transcribed verbatim. We used interpretive description methodology to inform the thematic analysis of the transcripts. RESULTS: Eight adolescents with a mean age of 15 years participated. Five adolescents identified as female; most were Indigenous (7/8). The mean duration since diagnosis of diabetes was 2.5 years. Adolescents reported struggling with acceptance of their diagnosis, with the stigma and shame associated with the diagnosis and with daily self-management tasks. Three themes were developed from the focus group discussions: bearing witness, the “weight” of diabetes and support (lack of support). INTERPRETATION: Adolescents with diagnoses of type 2 diabetes experience associated stigma and shame, which are substantial barriers to self-care. A broader understanding of their lived experience, including the socioecological and emotional context, could help to improve health care provision and intervention strategies for this population.

This study determined the interindividual variation in the cardiometabolic response to 6 months of moderate or vigorous intensity exercise training (ET) among youth at risk for type 2 diabetes mellitus. Youth were randomized to moderate intensity ET (45–55% heart rate reserve; n = 31), vigorous intensity ET (70–85% heart rate reserve; n = 37), or control (n = 36). Only those attending ≥70% of ET sessions were included. Cardiometabolic measures included insulin sensitivity, hepatic triglyceride content, visceral adipose area, and cardiorespiratory fitness. The contribution of ET to interindividual variation was determined using the standard deviation of individual responses (SDIR) and considered meaningful if the SDIR surpassed the smallest worthwhile difference (SWD), calculated as 0.2 × the standard deviation of the control group baseline values. ET meaningfully contributed to the interindividual variation among changes in peak oxygen uptake following moderate (SDIR: 2.04) and vigorous (SDIR: 3.43) ET (SWD: 1.17 mL·kg fat free mass−1·min−1), body fat percentage and hepatic triglyceride content following moderate-intensity ET (SDIR: 1.64, SWD: 1.05%; SDIR: 10.08, SWD: 1.06%, respectively), and visceral fat mass following vigorous ET (SDIR: 11.06, SWD: 7.13 cm2). Variation in the changes in insulin sensitivity were not influenced by ET. The contribution of ET to interindividual variation appears to be influenced by the desired outcome and prescribed intensity. Trial registration at ClinicalTrials.gov (identifier no.: NCT00755547). Novelty: The contribution of exercise to interindividual variation following training depends on the outcome and exercise intensity. Increasing exercise intensity does not systematically reduce non-response among youth at risk for type 2 diabetes.

OBJECTIVES There is emerging evidence that First Nations women with diabetes in pregnancy and their offspring have poorer health outcomes than non-First Nations women. The aim of this study was to describe the perinatal outcomes of pregnancies complicated by type 2 diabetes. METHODS The Next Generation longitudinal study is a First Nations birth cohort of children born to mothers diagnosed in childhood with type 2 diabetes. Pregnant women were prospectively enrolled in the birth cohort, and a review of medical records (including stored fetal ultrasound images) was performed to determine perinatal outcomes for 112 child-mother pairs between 2005 and 2015. Maternal demographics, antenatal variables, fetal ultrasound findings, obstetric and delivery information and neonatal birth outcomes were collected and analyzed. RESULTS Mothers in our cohort were young and most were overweight at the start of pregnancy. Most had suboptimal glycemic control in the first trimester (median glycated hemoglobin, 9.3%). The cesarean section rate was high at 41%. Over one-half of newborns had macrosomia at birth, and almost 1 in 5 were born with a structural anomaly, mainly renal. Fetal ultrasound significantly underestimated the proportion of infants born with macrosomia (p

The release of podocyte-derived microparticles into the urine may reflect early kidney injury in diabetes. We measured the urinary excretion of podocyte-derived microparticles in youth with type 1 and type 2 diabetes, and related the values to blood pressure, renal function and blood glucose levels. Cross-sectional, exploratory analysis of urine samples and clinical data from youth with type 1 (n = 53) and type 2 (n = 50) diabetes was carried out. Urinary podocyte-derived microparticle numbers, measured by flow cytometry, were assessed in relation to measures of blood glucose levels and renal function. Podocyte-derived microparticle excretion (MPE) normalised to urinary creatinine (MP/UCr) was higher in type 1 vs type 2 diabetes (median [IQR] MP/UCr: 7.88 [8.97] vs 1.84 [8.62]; p

Adrenal insufficiency (AI) remains a significant cause of morbidity and mortality in children with 1 in 200 episodes of adrenal crisis resulting in death. The goal of this working group of the Pediatric Endocrine Society Drug and Therapeutics Committee was to raise awareness on the importance of early recognition of AI, to advocate for the availability of hydrocortisone sodium succinate (HSS) on emergency medical service (EMS) ambulances or allow EMS personnel to administer patient's HSS home supply to avoid delay in administration of life-saving stress dosing, and to provide guidance on the emergency management of children in adrenal crisis. Currently, hydrocortisone, or an equivalent synthetic glucocorticoid, is not available on most ambulances for emergency stress dose administration by EMS personnel to a child in adrenal crisis. At the same time, many States have regulations preventing the use of patient's home HSS supply to be used to treat acute adrenal crisis. In children with known AI, parents and care providers must be made familiar with the administration of maintenance and stress dose glucocorticoid therapy to prevent adrenal crises. Patients with known AI and their families should be provided an Adrenal Insufficiency Action Plan, including stress hydrocortisone dose (both oral and intramuscular/intravenous) to be provided immediately to EMS providers and triage personnel in urgent care and emergency departments. Advocacy efforts to increase the availability of stress dose HSS during EMS transport care and add HSS to weight-based dosing tapes are highly encouraged.

Objective This study aimed to determine the degree of left ventricular (LV) dysfunction and its determinants in adolescents with type 2 diabetes (T2D). We hypothesized that adolescents with T2D would display impaired LV diastolic function and that these cardiovascular complications would be exacerbated in youth exposed to maternal diabetes in utero. Methods Left ventricular structure and function, carotid artery intima media thickness and strain, and serum metabolomic profiles were compared between adolescents with T2D (n = 121) and controls (n = 34). Sub-group analyses examined the role of exposure to maternal diabetes as a determinant of LV or carotid artery structure and function among adolescents with T2D. Results Adolescents with T2D were 15.1 ± 2.5 years old, (65% female, 99% Indigenous), had lived with diabetes for 2.7 ± 2.2 years, had suboptimal glycemic control (HbA1c = 9.4 ± 2.6%) and 58% (n = 69) were exposed to diabetes in utero. Compared to controls, adolescents with T2D displayed lower LV diastolic filling (early diastole/atrial filling rate ratio [E/A] = 1.9 ± 0.6 vs 2.2 ± 0.6, P = 0.012), lower LV relaxation and carotid strain (0.12 ± 0.05 vs 0.17 ± 0.05, P = .03) and elevated levels of leucine, isoleucine and valine. Among adolescents with T2D, exposure to diabetes in utero was not associated with differences in LV diastolic filling, LV relaxation, carotid strain or branched chain amino acids. Conclusions Adolescents with T2D display LV diastolic dysfunction, carotid artery stiffness, and elevated levels of select branch chain amino acids; differences were not associated with exposure to maternal diabetes in utero.

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 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.

Male sex is a risk factor for progression of diabetic kidney disease, but the reasons for this predilection are unclear. Here, we demonstrate that cell sex and sex hormones alter the metabolic phenotype of human proximal tubular epithelial cells (PTECs). Male PTECs displayed increased glycolysis, mitochondrial respiration, oxidative stress, apoptosis, and high glucose-induced injury, compared to female PTECs. This phenotype was enhanced by dihydrotestosterone (DHT) and linked to increased mitochondrial utilization of glucose and glutamine. Studies in vivo pointed towards increased glutamine anaplerosis in diabetic male kidneys. Male sex was linked to increased levels of glutamate, TCA cycle, and glutathione cycle metabolites, in PTECs and in the blood metabolome of healthy youth and youth with type 2 diabetes. Conversely, female PTECs displayed increased levels of pyruvate, glutamyl-cysteine, cysteinylglycine, and a higher GSH/GSSG ratio than male PTECs, indicative of enhanced redox homeostasis. Finally, we identified transcriptional mechanisms that control kidney metabolism in a sex-specific fashion. While X-linked demethylase KDM6A facilitated metabolic homeostasis in female PTECs, transcription factor HNF4A mediated the deleterious effects of DHT in male PTECs. This work uncovers the role of sex in glucose/glutamine metabolism, that may explain the roots of sex dimorphism in the healthy and diabetic kidney.

IntroductionYouth living with type 2 diabetes display increased risk of cardiovascular disease (CVD). It is unclear if regular physical activity (PA) modifies this risk.Research design and methodsWe compared CVD risk factors in a cross-sectional study of 164 youth with type 2 diabetes stratified according to weekly vigorous-intensity PA. Outcomes were hemoglobin A1c (HbA1c), ambulatory blood pressure (BP; ambulatory 24-hour readings), plasma lipoproteins, and albuminuria. The main exposure, vigorous-intensity PA, was quantified with the Adolescent Physical Activity Recall Questionnaire.ResultsYouth were 15±3 years, and 78% lived rurally and 68% were female, with a mean body mass index (BMI) Z-score of 2.4±1.1 and a mean HbA1c of 9.6% ±2.6%. Youth who participated in regular vigorous-intensity PA (40%; n=67) achieved nearly twice the dose of PA than peers who did not (62 vs 34 metabolic equivalent score-hour/week, p=0.001). After adjusting for duration of diabetes, BMI Z-score, sex, and smoking, youth who engaged in vigorous-intensity PA displayed lower HbA1c (9.1% vs 9.9%, p=0.052), diastolic BP (70 mm Hg vs 73 mm Hg, p=0.002), diastolic load (20% vs 26%, p=0.023), and mean arterial pressure (87.3 mm Hg vs 90.3 mm Hg, pConclusionsAmong youth with type 2 diabetes, participation in vigorous-intensity PA is associated with lower CVD risk.

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.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.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.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.

Background: In Canada and the United States, most families referred for pediatric weight management services do not start treatment. Of families who initiate care, many discontinue before ...

Objectives To compose and validate an electronic medical records–based case definition for pediatric diabetes in primary care. Methods Data from the electronic medical records of 221 primary care providers participating in the Manitoba Primary Care Research Network were extracted from April 1, 1998, to March 31, 2015. We assessed agreement among the 3 case definitions of pediatric diabetes and compared the performance of each with the clinical database of the Manitoba Diabetes Education Resource for Children and Adolescents. Results Our reference dataset included 41,055 pediatric patients. Electronic medical records–based case definitions, which included billing records, health conditions lists, prescription records and laboratory results, showed substantially higher sensitivity compared to the administration-based case definition that relied on billing and prescription records (96.9% and 94.9% vs 48.5%). Our study suggests a higher prevalence of pediatric diabetes in Manitoba than was previously reported through administration-based case definitions or in patients whose data were captured in the Manitoba Diabetes Education Resource for Children and Adolescents clinical database. Conclusions We describe a novel method of calculating the prevalence of pediatric diabetes in a primary care population. This case definition will improve the surveillance of pediatric diabetes and enhance service planning and the development of strategies to support prevention and management.

Pediatric type 2 diabetes mellitus (T2DM) patients are often overweight or obese, yet there are no validated clinical measures of adiposity to stratify cardiometabolic risk in this population. The tri-ponderal mass index (TMI, kg/m3) has recently been reported as a measure of adiposity in children, but there has been no validation of the association of TMI with adiposity in pediatric T2DM. We hypothesized that in children with T2DM, the TMI can serve as a more accurate measure of adiposity when compared to BMI z-score, and that it is associated with components of the metabolic syndrome. This is a cross-sectional secondary data analysis from the Improving Renal Complications in Adolescents with Type 2 Diabetes Through REsearch (iCARE) study (n = 116, age 10.20–17.90 years). Spearman’s correlations and multivariable regression were used in the analyses. When compared to DXA, TMI demonstrated significant correlation with total adiposity versus BMI z-score (TMI r = 0.74, p-value

AIMS: The aim of this study is to generate an in-depth understanding of youth perceptions and experiences of living with type 2 diabetes to inform knowledge translation, research and intervention development. DESIGN: Interpretive descriptive qualitative study. METHODS: Twenty to 25 youth aged 10-18 years with a diagnosis of type 2 diabetes will be purposively recruited through the Diabetes Education Resource for Children and Adolescents in Winnipeg, Manitoba, and through the Improving Renal Complications in Adolescents With Type 2 Diabetes Through the REsearch [iCARE] cohort. Socio-demographic information will be collected. Semi-structured interviews will occur iteratively with inductive thematic analysis. Data will be professionally transcribed and managed using NVivo 1.0 software. The University Ethics Committee approved this study (May 2020). DISCUSSION: There is a critical gap in understanding youth experiences of type 2 diabetes. Research involving youth with type 2 diabetes is predominantly quantitative in nature, largely reflecting risk factors, underlying mechanisms and treatment outcomes associated with diabetes management. In-depth qualitative research on youth experiences can help identify youth priorities, provide insight into critical misalignments between stakeholder perspectives, and drive forward a more consolidated youth-centred research agenda. IMPACT: Understanding and applying knowledge of youth experiences is critical as the prevalence of, and challenges associated with, youth onset type 2 diabetes continues to increase worldwide. This research will generate a robust interpretive description of youth lived experiences and perceptions of type 2 diabetes where such research is lacking, to inform basic and applied research within an interdisciplinary investigative and clinical research team with relevance to other jurisdictions. In response to calls for youth-oriented research in type 2 diabetes, this work will catalyse collaborative knowledge translation using creative and youth-directed initiatives.

Background: First Nations (FN) women have a higher risk of diabetes than non-FN women in Canada. Prenatal education and breastfeeding may reduce the risk of diabetes in mothers and offspring. The rates of breastfeeding initiation and participation in the prenatal program are low in FN communities. Methods: A prenatal educational website, social media-assisted prenatal chat groups and community support teams were developed in three rural or remote FN communities in Manitoba. The rates of participation of pregnant women in prenatal programs and breastfeeding initiation were compared before and after the start of the remote prenatal education program within 2014-2017. Findings: The participation rate of FN pregnant women in rural or remote communities in the prenatal program and breastfeeding initiation during 1-year after the start of the community-based remote prenatal education program were significantly increased compared to that during 1-year before the start of the program (54% versus 36% for the participation rate, 50% versus 34% for breastfeeding initiation, p

The impacts of stress and disrupted sleep on type 2 diabetes management and related comorbidities in adolescents and youth remain unknown. In this study, we examine sleep in adolescents and youth living with type 2 diabetes and matched controls and its association with stress, glycemic management, albuminuria and hypertension.A cross-sectional analysis was conducted to assess the relationship between sleep quality (Pittsburgh Sleep Quality Index [PSQI]) and stress (Perceived Stress Scale-14 [PSS-14] and Kessler Psychological Distress Scale [K6]) with metabolic control within a cohort of male and female adolescents and youth (10 to 23 years old) with type 2 diabetes and weight- and ethnicity-matched controls.One hundred eighty-one adolescents and youth with type 2 diabetes (15.0±2.44 years of age, body mass index z score [BMIz] 1.85±0.60, 62.5% female) and 52 controls (16±2.9 years, BMIz 1.99±0.58, 61.5% female) were included in the investigation. Participants slept for an average of 8.38 hours per night, and 49% of individuals with type 2 diabetes and 46% of controls rated their sleep quality as "poor." No sex differences were seen for sleep scores (p=0.13), but females reported higher stress (p=0.001) and distress (p=0.03). No differences in glycated hemoglobin (p=0.11), BMIz (p=0.28), hypertension (p=0.24) or albuminuria (p=0.79) were seen in individuals reporting good vs poor sleep. Regression analysis showed that poor sleep was associated with higher glycated hemoglobin (p=0.029).Many adolescents and youth reported poor sleep, which was associated with stress, distress and worse glycemic management. Differences were observed between sexes. The long-term effects of poor sleep and psychological distress warrant further study.

The release of podocyte-derived microparticles into the urine may reflect early kidney injury in diabetes. We measured the urinary excretion of podocyte-derived microparticles in youth with type 1 and type 2 diabetes, and related the values to blood pressure, renal function and blood glucose levels.Cross-sectional, exploratory analysis of urine samples and clinical data from youth with type 1 (n = 53) and type 2 (n = 50) diabetes was carried out. Urinary podocyte-derived microparticle numbers, measured by flow cytometry, were assessed in relation to measures of blood glucose levels and renal function.Podocyte-derived microparticle excretion (MPE) normalised to urinary creatinine (MP/UCr) was higher in type 1 vs type 2 diabetes (median [IQR] MP/UCr: 7.88 [8.97] vs 1.84 [8.62]; p 0.0001), despite the type 2 diabetes group having higher blood pressure (systolic blood pressure, median [range]: 124 [110-154] vs 114 [94-143] mmHg) and higher proportions of microalbuminuria (44.0% vs 13.2%), but shorter time since diabetes diagnosis (median [range]: 1.2 [0.0-7.0] vs 6.4 [2.0-13.9] years), than the type 1 diabetes cohort. MPE in youth with type 1 diabetes was associated with blood glucose (p = 0.01) and eGFR (p = 0.03) but not HbASignificant associations between podocyte MPE, blood glucose levels and eGFR were observed in youth with type 1 diabetes but not in those with type 2 diabetes, notwithstanding increased renal pathology in the type 2 diabetes cohort. These findings suggest that podocyte injury differs in the two diabetes cohorts. Graphical abstract.

Introduction: Mental health comorbidities are common in persons with type 2 diabetes (T2D). The magnitude of mental health comorbidities in youth with T2D and possible protective factors against comorbidities, remain unclear, as previous studies have not compared outcomes with population-based samples or included measures of resilience. Methods: We performed a cross-sectional analysis of 178 Indigenous youth (15 yrs IQR: 13-17 yrs) with T2D from the iCARE cohort study and 270 randomly sampled population-based controls (15-24 yrs), from the Canadian Community Health Survey - Mental Health Component. Overall positive mental health and flourishing were assessed with the Mental Health Continuum-Short Form. Depression, anxiety and severe mental illness (SMI) were assessed with the Kessler Distress Scale. Measures of resilience were assessed in youth with T2D using the 64-question Resiliency Scales for Children and Adolescents. Results: Youth with T2D, were more likely to be female (65 vs. 49%), Indigenous (96 vs. 29%), live remotely (70 vs. 26%) and within a low income neighbourhood (p Conclusion: Youth with T2D live with a profound degree of mental health comorbidities relative to the general population of in Manitoba, Canada. Future studies are required to address the specific mental health needs youth with T2D and determined best clinical care practices. Disclosure J. Mcgavock: None. B. Wicklow: None. E. Sellers: None.

Background: Youth living with type 2 diabetes (T2D) are characterized by an increased cardiovascular disease (CVD) risk profile. It is unclear if regular vigorous intensity physical activity (PA) modifies this CVD risk. Methods: Using a cross-sectional design, we compared cardiometabolic risk factors among 164 youth with T2D from the The Improving renal Complications in Adolescents with T2D through REsearch (iCARE) cohort, stratified according to participation in vigorous intensity organized sport. Outcomes of interest were HbA1c, ambulatory blood pressure (BP) parameters from 24 hr monitoring, hypertension according to 2017 American Academy of Pediatrics criteria and albuminuria determined from first morning urine samples. The main exposure, regular (≥ 3 days/week) participation in vigorous intensity organized sport was determined from a validated questionnaire (Adolescent Physical Activity Questionnaire). Results: Youth were 15 ± 3 yrs, 78% lived in a rural town, 68% were girls, mean BMI Z score was 2.4 ± 1.1 and mean HbA1c was 9.6 ± 2.6%. Youth that participated in regular vigorous intensity organized sport (40%; n=67) achieved nearly twice the dose of PA than less active peers (176 vs. 108 MET-HR/week; p=0.001). After adjusting for duration of diabetes, BMI Z score, sex and current smoking status, youth with T2D who engaged in regular vigorous intensity organized sport displayed lower HbA1c (9.1%, vs. 9.9% p = 0.052), diastolic BP (70 vs. 73 mmHg, p = 0.002) and diastolic load (20 vs. 26%, p = 0.023). Compared to youth that did not participate in regular vigorous intensity organized sport, those who did displayed a lower odds of albuminuria (OR: 0.40 95% CI: 0.19-0.84) and hypertension (OR: 0.39 95% CI: 0.16-0.95). Conclusions: Among youth living with T2D, self-reported frequent participation in vigorous organized sport is associated with lower CVD risk. These data need to be confirmed with prospective observational and experimental data. Disclosure J.L. Slaght: None. A. Dart: None. T. Blydt-Hansen: None. E. Sellers: None. B. Wicklow: None. J.

Objectives: There is limited data on MID in children. This study aimed to compare the demographic and clinical characteristics of 1) a historical MID cohort to a new cohort and 2) children with MID based on overweight/obese BMI (O-BMI) and normal weight BMI (N-BMI). Methods: National surveillance was conducted via the CPSP. Pediatric clinicians reported new cases (children Results: There were 55 cases of MID in cohort 1 and 51 cases in cohort 2, with no significant differences between cohorts. Mean age (+/- SD) at presentation was 13.1 +/- 3.6 years and 13.3 +/- 3.5 years in cohort 1 and 2, respectively. Glucocorticoid therapy was documented in >95% of cases in both cohorts. In the combined cohorts there were 50 cases with N-BMI and 43 cases with O-BMI. There were no statistically significant differences in age, sex or ethnicity across BMI groups. Mean hemoglobin A1c (+/- SD) (n = 40) was 6.45% +/- 1.11% in the N-BMI group and 7.26% +/- 2.51% in the O-BMI group (p = 0.184). The O-BMI group were more likely to have a parent with type 2 diabetes (T2D) (p = 0.042) and acanthosis nigricans (p = 0.007) compared to the N-BMI group. Conclusions: The demographic and clinical features of children with MID have not changed over a 10-year period. The presence of acanthosis nigricans and/or a parent with T2D may be used to identify children who require more intensive glycemic monitoring when on a diabetogenic medication. Further studies are needed to better understand the evolution of MID and the risk it confers to developing T2D. Disclosure T.J. Patel: None. A. Ayub: None. M.A. Irvine: None. S. Hadjiyannakis: None.

BACKGROUND: It is unclear whether intrauterine exposure to maternal diabetes is associated with risk factors for cardiovascular disease and related end points in adulthood. We examined this potential association in a population-based birth cohort followed up to age 35 years. METHODS: We performed a cohort study of offspring born between 1979 and 2005 (n = 293 546) and followed until March 2015 in Manitoba, Canada, using registry-based administrative data. The primary exposures were intrauterine exposure to gestational diabetes and type 2 diabetes mellitus. The primary outcome was a composite measure of incident cardiovascular disease events, and the secondary outcome was a composite of risk factors for cardiovascular disease in offspring followed up to age 35 years. RESULTS: The cohort provided 3 628 576 person-years of data (mean age at latest follow-up 20.5 [standard deviation 6.4] years, 49.3% female); 2765 (0.9%) of the offspring experienced a cardiovascular disease end point, and 12 673 (4.3%) experienced a cardiovascular disease risk factor. After propensity score matching, the hazard for cardiovascular disease end points was elevated in offspring exposed to gestational diabetes (adjusted hazard ratio [HR] 1.42, 95% confidence interval [CI] 1.12–1.79) but not type 2 diabetes (adjusted HR 1.40, 95% CI 0.98–2.01). A similar association was observed for cardiovascular disease risk factors (gestational diabetes: adjusted HR 1.92, 95% CI 1.75–2.11; type 2 diabetes: adjusted HR 3.40, 95% CI 3.00–3.85). INTERPRETATION: Intrauterine exposure to maternal diabetes was associated with higher morbidity and risk related to cardiovascular disease among offspring up to 35 years of age.

AIMS/HYPOTHESIS Youth with type 2 diabetes (T2D) have high rates of obesity, hypertension and suboptimal glycemic control. We hypothesized that renin-angiotensin system (RAS) activation is present in youth with T2D and associated with poor glycemic control and renal outcomes. METHODS Cross-sectional analysis of 183 youth with T2D and 100 controls from the Improving renal Complications in Adolescents with T2D through REsearch cohort. Diabetes youth stratified by urine albumin:creatinine ratio (ACR) < or ≥2 mg/mmol. RAS levels measured with enzyme-linked immunosorbent assay (ELISA) and enzyme activities by synthetic substrates. In T2D, levels log transformed and Tobit linear regressions evaluated for associations with hemoglobin A1c (HbA1c), mean arterial pressure (MAP), estimated glomerular filtration rate (eGFR), ACR. RESULTS Youth were 14 to 15 years, with diabetes duration 1.7 to 1.8 years; 21.3% albuminuria. Serum: differences in plasma renin activity (

Healthcare transition refers to the transition of care for youth with chronic disease from pediatric-oriented healthcare services to adult-oriented services. The primary goal of transition is to ensure that the move to adult healthcare services occurs seamlessly, resulting in continuity of care in a comprehensive, developmentally appropriate manner. Type 1 and type 2 diabetes are chronic illnesses significantly impacted by transition from pediatric to adult care. Successful transition requires a focused and purposeful process to optimize lifelong outcomes. This chapter aims to review aspects of transition of youth with both type 1 and type 2 diabetes to adult healthcare services. This includes models of transition care; patient, provider, and program characteristics; and the assessment of a patient’s transition readiness. In addition, we will address gaps in our understanding of this process and future needs to best support the population of adolescents and emerging adults with type 1 and type 2 diabetes.

Indigenous women and children experience some of the most profound health disparities globally. These disparities are grounded in historical and contemporary trauma secondary to colonial atrocities perpetuated by settler society. The health disparities that exist for chronic diseases may have their origins in early-life exposures that Indigenous women and children face. Mechanistically, there is evidence that these adverse exposures epigenetically modify genes associated with cardiometabolic disease risk. Interventions designed to support a resilient pregnancy and first 1000 days of life should abrogate disparities in early-life socioeconomic status. Breastfeeding, prenatal care and early child education are key targets for governments and health care providers to start addressing current health disparities in cardiometabolic diseases among Indigenous youth. Programmes grounded in cultural safety and co-developed with communities have successfully reduced health disparities. More works of this kind are needed to reduce inequities in cardiometabolic diseases among Indigenous women and children worldwide.

OBJECTIVE The aim of this study was to determine whether the readiness for adopting healthy lifestyle behaviors was associated with mental health and comorbid conditions in youth with T2D. METHODS A cross-sectional comparison of various measures of mental health (distress, stress, resilience) and comorbid conditions (glycated hemoglobin, adiposity, hypertension) was conducted within a cohort of indigenous youth with T2D living in Canada, stratified according to their readiness to adopt healthy lifestyle behaviors based on Prochaska's transtheoretical model. RESULTS Within the entire cohort (n = 162), only 14% were considered ready to adopt all healthy lifestyle behaviors. The readiness to adopt all lifestyle behaviors was associated with higher positive mental health (47 vs. 39 units; P

Since 1980, global obesity has doubled, and the incidence of cardiometabolic diseases such as type 2 diabetes and heart disease is also increasing. While genetic susceptibility and adult lifestyle are implicated in these trends, evidence from clinical cohorts, epidemiological studies and animal model experiments support a role for early-life environmental exposures in determining the long-term health of an individual, which has led to the formulation of the Developmental Origins of Health and Disease (DOHaD) theory. In fact, maternal obesity and diabetes during pregnancy, which are on the rise, are strongly associated with altered fetal growth and development as well as with lifelong perturbations in metabolic tissues. A mounting body of evidence implicates epigenetic mechanisms (e.g. DNA methylation and histone modifications) in the regulation of these effects and their transmission to future generations. This review critically discusses the current evidence (in animal model systems and humans) that implicates maternal obesity and diabetes during pregnancy in perturbing the epigenome of the next generation, and the consequential impact on growth, organ development and ultimately cardiometabolic disease progression. Additionally, this review will address some of the limitations of the DOHaD approach and areas that require further study. For example, future research requires verification of the mechanistic impact of the epigenetic marks and their persistence over the life course. Ultimately, this knowledge is needed to establish optimal screening, prevention and therapeutic approaches for children at risk of cardiometabolic disease development.

Objectives To describe the paediatric transgender population accessing health care through the Manitoba Gender Dysphoria Assessment and Action for Youth (GDAAY) program, and report youth's experiences accessing health care in Manitoba. Methods Demographic, medical, surgical and mental health information was extracted from the medical records of youth referred to the GDAAY program (n=174). A 77-item online survey was conducted with a subset of those youth (n=25) to identify common health care experiences and perceptions of trans youth in Manitoba. Results Chart review of 122 natal females and 52 natal males, ranging in age from 4.7 to 17.8 years (mean 13.9 years), found 66 patients (46.8%) with a pre-existing or current mental health diagnosis, of which anxiety and depression were the most common (n=43, 30.5%). Qualitative self-reports revealed all patients had negative interactions with health care providers at some point, many having experienced lack of engagement with the medical system due to reported lack of knowledge by the provider on trans-related health services. Conclusion Transgender youth in Manitoba seeking GDAAY services have high rates of anxiety and depression. These youth face adversity in health care settings and are distressed over long wait times for mental health services. Recommendations to improve care include increasing general health care providers' education on gender affirmative care, providing gender sensitivity training for health care providers, gathering preferred names and pronouns during triage, increasing visibility of support for LGBT+ persons in clinics, increasing resource allocation to this field and creating policies so all health care settings are safe places for trans youth.
