Association of stigma, diabetes distress and self-efficacy with quality of life in adolescents with type 1 diabetes preparing to transition to adult care.

AIMS: In type 1 diabetes (T1D), psychosocial factors may impact quality of life (QOL) and clinical outcomes, but remain understudied, particularly during late adolescence. Our aim was to determine whether stigma, diabetes distress and self-efficacy are associated with QOL in adolescents with T1D as they are preparing to transition to adult care. METHODS: We conducted a cross-sectional study of adolescents (ages 16-17 years) with T1D participating in the Group Education Trial to Improve Transition (GET-IT) in Montreal, Canada. Participants completed validated questionnaires on stigma using the Barriers to Diabetes Adherence (BDA) stigma subscale, self-efficacy (Self-Efficacy for Diabetes Self-Management Measure [SEDM], score 1-10), diabetes distress (Diabetes Distress Scale for Adults with type 1 diabetes) and QOL (Pediatric Quality of Life Inventory [PedsQL] 4.0 Generic Core Scale and PedsQL 3.2 Diabetes Module). We examined associations of stigma, diabetes distress and self-efficacy with QOL using multivariate linear regression models adjusted for sex, diabetes duration, socioeconomic status and HbA1c. RESULTS: Of 128 adolescents with T1D, 76 (59%) self-reported having the diabetes-related stigma and 29 (22.7%) reported experiencing diabetes distress. Those with stigma had lower diabetes-specific and general QOL scores compared with those without stigma, and stigma and diabetes distress were both associated with lower diabetes-specific QOL and lower general QOL. Self-efficacy was associated with higher diabetes-specific and general QOL. CONCLUSIONS: Stigma and diabetes distress are associated with lower QOL, whereas self-efficacy is associated with higher QOL in adolescents with T1D preparing to transfer to adult care.

Diabetes duration, perceived comfort with self-management and glycaemic control in adolescents with type 1 diabetes: A cross-sectional study.

AIMS: Evidence is lacking on whether diabetes duration is associated with type 1 diabetes (T1D) self-management during late adolescence before transfer from paediatric to adult care. We examined associations of diabetes duration with dimensions of perceived comfort with diabetes self-management (self-efficacy, transition readiness, diabetes distress) and glycaemic control in late adolescence. METHODS: Using a cross-sectional design, we conducted a secondary analysis of baseline data of adolescents (ages 16-17 years) with T1D followed at paediatric diabetes academic hospitals in Montreal and enrolled in the Group Education Trial to Improve Transition (GET-IT-T1D). Participants completed validated questionnaires on self-efficacy (Self-Efficacy for Diabetes Self-Management Measure [SEDM], score 1 to 10), diabetes distress and transition readiness, as well as a haemoglobin (HbA1c) capillary blood test. Our primary outcome was self-efficacy. We examined associations of diabetes duration with self-efficacy, diabetes distress, transition readiness and HbA1c using linear and logistic regression models adjusted for sex, socioeconomic status, insulin pump use, glucose sensor use and psychiatric comorbidity. RESULTS: Of 203 adolescents with T1D, mean diabetes duration (SD) was 7.57 (4.44) years. Mean SEDM score was 6.83 (SD 1.62). Diabetes duration was not associated with self-efficacy, diabetes distress or transition readiness. Each additional year of diabetes duration was associated with 0.11% (95% CI, 0.05 to 0.16) higher HbA1c. CONCLUSIONS: Although diabetes duration is not associated with dimensions of perceived comfort with diabetes self-management, adolescents with longer diabetes duration are at risk for higher HbA1c and may need additional support to improve glycaemic control before transition to adult care.

Supporting and Incentivizing Peer Leaders for an Internet-Based Private Peer Community for Youths With Type 1 Diabetes: Social Network and Directed Content Analysis.

BACKGROUND: Youths with type 1 diabetes (T1D) frequently experience stigma. Internet-based peer communities can mitigate this through social support but require leaders to catalyze exchange. Whether nurturing potential leaders translates into a central role has not been well studied. Another issue understudied in such communities is lurking, the viewing of exchanges without commenting or posting. OBJECTIVE: We aimed to assess the centrality of the peer leaders we selected, trained, and incentivized within the Canadian Virtual Peer Network (VPN)-T1D. This is a private Facebook (Meta Platforms, Inc) group that we created for persons aged 14 to 24 years with T1D. We specifically sought to (1) compare a quantitative estimate of network centrality between peer leaders and regular members, (2) assess the proportions of network exchanges that were social support oriented, and (3) assess proportions of high engagement (posts, comments, reactions, and votes) and low engagement (lurking) exchanges. METHODS: We recruited peer leaders and members with T1D from prior study cohorts and clinics. We trained 10 leaders, provided them with a monthly stipend, and encouraged them to post on the private Facebook group we launched on June 21, 2017. We extracted all communications (posts, messages, reactions, polls, votes, and views) that occurred until March 20, 2020. We calculated each member's centrality (80% of higher engagement communications comprising posts, comments, and reactions plus 20% of members with whom they connected). We divided each member's centrality by the highest centrality to compute the relative centrality, and compared the mean values between leaders and members (linear regression). We calculated the proportions of communications that were posts, comments, reactions, and views without reaction. We performed content analysis with a social support framework (informational, emotional, esteem-related, network, and tangible support), applying a maximum of 3 codes per communication. RESULTS: VPN-T1D gained 212 regular members and 10 peer leaders over 33 months; of these 222 members, 26 (11.7%) exited. Peer leaders had 10-fold higher relative centrality than regular members (mean 0.53, SD 0.26 vs mean 0.04, SD 0.05; 0.49 difference; 95% CI 0.44-0.53). Overall, 91.4% (203/222) of the members connected at least once through posts, comments, or reactions. Among the 75,051 communications, there were 5109 (6.81%) posts, comments, and polls, 6233 (8.31%) reactions, and 63,709 (84.9%) views (lurking). Moreover, 54.9% (3430/6253) of codes applied were social support related, 66.4% (2277/3430) of which were informational (eg, insurance and travel preparation), and 20.4% (699/3430) of which were esteem related (eg, relieving blame). CONCLUSIONS: Designating, training, and incentivizing peer leaders may stimulate content exchange and creation. Social support was a key VPN-T1D deliverable. Although lurking accounted for a high proportion of the overall activity, even those demonstrating this type of passive participation likely derived benefits, given that the network exit rate was low.

Toward a better understanding of transition from paediatric to adult care in type 1 diabetes: A qualitative study of adolescents.

AIMS: Type 1 diabetes is associated with significant morbidity, with an increasing risk of acute diabetes-related complications in adolescence and emerging adulthood. Purposeful transition from paediatric to adult-oriented care could mitigate this risk but is often lacking. Detailed understanding of the perspectives of adolescents in their final year of paediatric care is essential to inform delivery of transition care programs. METHODS: We conducted semi-structured interviews with adolescents (aged 17 years) with type 1 diabetes at an academic institution from April 2017 to May 2018. Participants were recruited through convenience sampling. Sixty-one interviews were transcribed for analysis. Coding followed the principles of thematic analysis. RESULTS: Thirty-six percent of participants were male, and participants were from diverse socioeconomic backgrounds. We found three overarching themes in our analysis: first, difficulties navigating changing relationships with parents and healthcare teams; second, the need to increase type 1 diabetes self-management and differing comfort levels based on age of diagnosis; and third, perceived responsibilities for transition care preparation (for both the paediatric team and adolescents themselves) focused not only on type 1 diabetes-specific skills but also on healthcare system structures. CONCLUSIONS: Our findings suggest that novel transition programs addressing changing inter-personal relationships, disease-specific self-management (adapted for age of diagnosis), and healthcare system navigation, supported by parents and peers, may be needed to improve transition care for adolescents with type 1 diabetes.

Psychiatric disorders in emerging adults with diabetes transitioning to adult care: A retrospective cohort study.

AIMS: During transition from paediatric to adult diabetes care, adolescents with diabetes are at increased risk of psychiatric disorders compared with those without diabetes. Prolonged gaps between the last paediatric and first adult diabetes care visit are associated with higher perceived stress and lower life satisfaction. We assessed the effect of a gap (>180 days) in establishing adult diabetes care on the risk of psychiatric disorders and determined other risk factors associated with psychiatric disorders during the transfer to adult care. METHODS: Using provincial health administrative databases, we conducted a retrospective cohort study of individuals from Québec, Canada, diagnosed with diabetes between ages 1 and 15 years in 1997-2015. These individuals were followed from 6 months after their last paediatric visit until age 25 years. We used multivariable Cox proportional hazard models to determine the association of gap in care with psychiatric disorders risk. RESULTS: Among 1772 youth with diabetes, 740 (42%) had a gap in care. There was a non-statistically significant association between gap in care and mood disorders diagnosed in the emergency department or hospital (hazard ratio [HR] 1.38, 95% confidence interval [CI]: [0.92, 2.07]). Older age at transfer, recent birth year and higher number of all-cause emergency department visits in the year before transfer increased the risks of psychiatric disorders. CONCLUSIONS: Prolonged gaps in care during transfer to adult care are common and may be associated with increased psychiatric disorder risk. Developmental factors associated with adolescence and emerging adulthood may further amplify this risk.

Gestational diabetes associated with incident diabetes in childhood and youth: a retrospective cohort study.

BACKGROUND: Indicators of childhood- and youth-onset diabetes may be useful for early detection of diabetes; there is a known association between composite exposure of parental type 2 diabetes and gestational diabetes mellitus with childhood- and youth-onset diabetes. We examined associations between gestational diabetes mellitus and incidence of childhood- and youth-onset diabetes in offspring. METHODS: Using public health insurance administrative databases from Quebec, Canada, we randomly selected singleton live births with maternal gestational diabetes mellitus (1990-2007) and matched them 1:1 with singleton live births without gestational diabetes mellitus. Follow-up was to Mar. 31, 2012. We examined associations of diabetes in offspring with maternal gestational diabetes mellitus through unadjusted and adjusted Cox proportional hazards models. In secondary analyses, we separately considered age groups ranging from birth to age 12 years, and age 12 to 22 years. RESULTS: Incidence of pediatric diabetes (per 10 000 person-years) was higher in offspring born to mothers with gestational diabetes mellitus (4.52, 95% confidence interval [CI] 4.47-4.57) than in mothers without gestational diabetes mellitus (2.4, 95% CI 2.37-2.46). In an adjusted Cox proportional hazards model, maternal gestational diabetes mellitus was associated with development of pediatric diabetes overall (birth to age 22 yr: hazard ratio [HR] 1.77, 95% CI 1.41-2.22), during childhood (birth to age 12 yr: HR 1.43, 95% CI 1.09-1.89), and in youth (age 12 to 22 yr: HR 2.53, 95% CI 1.67-3.85). INTERPRETATION: Gestational diabetes mellitus is associated with incident diabetes in offspring during childhood and adolescence. Future studies are needed to examine longer-term outcomes in patients with pediatric diabetes with a maternal history of gestational diabetes mellitus, to ascertain how they compare with other patients with childhood- or youth-onset diabetes, in terms of disease severity and outcomes.

Risk of ketoacidosis in children at the time of diabetes mellitus diagnosis by primary caregiver status: a population-based retrospective cohort study.

BACKGROUND: Diabetic ketoacidosis is the leading cause of death among children with type 1 diabetes mellitus, and is an avoidable complication at first-time diagnosis of diabetes. Because having a usual provider of primary care is important in improving health outcomes for children, we tested the association between having a usual provider of care and risk of diabetic ketoacidosis at onset of diabetes. METHODS: Using linked health administrative data for the province of Quebec, we conducted a population-based retrospective cohort study of children aged 1-17 years in whom diabetes was diagnosed from 2006 to 2015. We estimated adjusted risk ratios (RRs) for an episode of diabetic ketoacidosis at the time of diabetes diagnosis in relation to usual provider of care (family physician, pediatrician or none) using Poisson regression models with robust error variance. RESULTS: We identified 3704 new cases of diabetes in Quebec children from 2006 to 2015. Of these, 996 (26.9%) presented with diabetic ketoacidosis. A decreased risk of this complication was associated with having a usual provider of care; the association was stronger with increasing age, reaching statistical significance among those aged 12-17 years. Within this age group, those who had a family physician or a pediatrician were 31% less likely (adjusted RR 0.69, 95% confidence interval [CI] 0.56-0.85) or 38% less likely (adjusted RR 0.62, 95% CI 0.45-0.86), respectively, to present with diabetic ketoacidosis, relative to those without a usual provider of care. INTERPRETATION: For children with newly diagnosed diabetes, having a usual provider of care appears to be important in decreasing the risk of diabetic ketoacidosis at the time of diabetes diagnosis. Our results provide further evidence concerning the need for initiatives that promote access to primary care for children.

Stigma and Its Association With Glycemic Control and Hypoglycemia in Adolescents and Young Adults With Type 1 Diabetes: Cross-Sectional Study.

BACKGROUND: Qualitative studies in type 1 diabetes indicate that visibility of diabetes supplies, self-care, and hypoglycemia symptoms are associated with stigma and suboptimal management. This may be particularly salient in youth who face concurrent challenges such as establishing autonomy and making vocational choices. OBJECTIVE: The aim of the study was to estimate stigma prevalence in youth (aged 14-24 years) with type 1 diabetes and its associations with glycemic control. METHODS: Participants, recruited largely through social media, were asked to complete a Web-based survey and to send via mail capillary blood samples for glycated hemoglobin (HbA1c) measurement. The primary definition of stigma required endorsement of one or more of 3 stigma-specific items of the Barriers to Diabetes Adherence questionnaire. These addressed avoidance of diabetes management with friends present, difficulty telling others about diabetes diagnosis, and embarrassment in performing diabetes care with others present. Poor glycemic control was defined as HbA1c>9% (ie, >75 mmol/mol; measured value when available, else self-report) and/or ≥1 severe hypoglycemic episode in the previous year (reported requiring assistance from someone else during the episode). Stigma prevalence was computed (95% CI), and associations with glycemic control were evaluated (multivariate logistic regression models). RESULTS: Among the 380 respondents, stigma prevalence was 65.5% (95% CI 60.7-70.3). Stigma was associated with a 2-fold higher odds of poor glycemic control overall (odds ratio [OR] 2.25, 95% CI 1.33-3.80; adjusted for age, sex, and type of treatment). There were specific associations with both HbA1c>9% (75 mmol/mol; OR 3.05, 95% CI 1.36-6.86) and severe hypoglycemia in the previous year (OR 1.86, 95% CI 1.05-3.31). CONCLUSIONS: There is a high prevalence of stigma in youth with type 1 diabetes that is associated with both elevated HbA1c levels and severe hypoglycemia. Targeted strategies to address stigma are needed.

Patterns of Gestational Hypertension or Preeclampsia Across 2 Pregnancies in Relationship to Chronic Hypertension Development: A Retrospective Cohort Study.

BACKGROUND: Gestational hypertension (GHTN) and preeclampsia are established risk indicators for chronic hypertension. While recurrence is associated with a greater risk, it is unclear whether there are differences in risk when these gestational complications occur for the first time in an earlier pregnancy versus first occurrence in a subsequent one. We hypothesized that the absence of recurrence reflects a transition toward a lower hypertension risk trajectory, whereas a new occurrence in a later pregnancy indicates a transition toward elevated risk. METHODS AND RESULTS: We analyzed linked data in Quebec, Canada, from public health care insurance administrative databases and birth, stillbirth, and death registries. Our retrospective cohort study included mothers with 2 singleton deliveries between April 1990 and December 2012. The primary exposure was patterns of GHTN or preeclampsia across 2 pregnancies (GHTN/preeclampsia in neither, first only, second only, or both). The outcome was incident chronic hypertension. We performed an adjusted multivariable Cox regression analysis. Among 431 980 women with 2 singleton pregnancies, 27 755 developed hypertension during the follow-up period. Compared with those without GHTN/preeclampsia, those with GHTN/preeclampsia only in the first pregnancy had a 2.7-fold increase in hazards (95% CI, 2.6-2.8), those with GHTN/preeclampsia only in the second had a 4.9-fold increase (95% CI, 4.6-5.1), and those with GHTN/preeclampsia in both pregnancies experienced a 7.3-fold increase (95% CI, 6.9-7.6). Patterns and estimates were similar when we considered GHTN and preeclampsia separately. CONCLUSIONS: The magnitude of hypertension risk is associated with the number and sequence of GHTN/preeclampsia-affected pregnancies. Considering both allows more personalized risk estimates.

Incident Diabetes in Women With Patterns of Gestational Diabetes Occurrences Across 2 Pregnancies.

Importance: Gestational diabetes is a type 2 diabetes risk indicator, and recurrence further augments risk. In women with a single occurrence across 2 pregnancies, it is unclear whether first- vs second-pregnancy gestational diabetes differ in terms of risk. Objective: To compare the hazards of incident diabetes among those with gestational diabetes in the first, in the second, and in both pregnancies with women without gestational diabetes in either. Design, Setting, and Participants: This was a retrospective cohort study with cohort inception from April 1, 1990, to December 31, 2012. Follow-up was April 1, 1990, to April 1, 2019. Participants were mothers with 2 singleton deliveries between April 1, 1990, and December 31, 2012, without diabetes before or between pregnancies, who were listed in public health care insurance administrative databases and birth, stillbirth, and death registries in Quebec, Canada. Data were analyzed from July to December 2023. Exposure: Gestational diabetes occurrence(s) across 2 pregnancies. Main outcomes and measures: Incident diabetes from the second delivery until a third pregnancy, death, or the end of the follow-up period, whichever occurred first. Results: The 431 980 women with 2 singleton deliveries studied had a mean (SD) age of 30.1 (4.5) years at second delivery, with a mean (SD) of 2.8 (1.5) years elapsed between deliveries; 373 415 (86.4%) were of European background, and 78 770 (18.2%) were at the highest quintile of material deprivation. Overall, 10 920 women (2.5%) had gestational diabetes in their first pregnancy, 16 145 (3.7%) in their second, and 8255 (1.9%) in both (12 205 incident diabetes events; median [IQR] follow-up 11.5 [5.3-19.4] years). First pregnancy-only gestational diabetes increased hazards 4.35-fold (95% CI, 4.06-4.67), second pregnancy-only increased hazards 7.68-fold (95% CI, 7.31-8.07), and gestational diabetes in both pregnancies increased hazards 15.8-fold (95% CI, 15.0-16.6). Compared with first pregnancy-only gestational diabetes, second pregnancy-only gestational diabetes increased hazards by 76% (95% CI, 1.63-1.91), while gestational diabetes in both pregnancies increased it 3.63-fold (95% CI, 3.36-3.93). Conclusions and relevance: In this retrospective cohort study of nearly half a million women with 2 singleton pregnancies, both the number and ordinal pregnancy of any gestational diabetes occurrence increased diabetes risk. These considerations offer greater nuance than an ever or never gestational diabetes dichotomy.

Suicidal Ideation, Suicide Attempts, and Suicide Deaths in Adolescents and Young Adults With Type 1 Diabetes: A Systematic Review and Meta-analysis.

BACKGROUND: Evidence is lacking on the risk of suicide-related behaviors (suicidal ideation, suicide attempt, suicide death) in youth with type 1 diabetes (T1D). PURPOSE: We aimed to 1) determine the prevalence of suicidal ideation, suicide attempts, and suicide deaths in adolescents and young adults (AYA) with T1D aged 10-24 years; 2) compare suicide-related behavior prevalence in youth with and without T1D; and 3) identify factors associated with suicide-related behaviors. DATA SOURCES: A systematic search was conducted in MEDLINE, Embase, and PsycInfo up to 3 September 2023. STUDY SELECTION: We included observational studies where investigators reported the prevalence of suicide-related behaviors among AYA aged 10-24 years with T1D. DATA EXTRACTION: We collected data on study characteristics, data on prevalence of suicide-related behaviors, and data on associated factors. DATA SYNTHESIS: We included 31 studies. In AYA with versus without T1D, pooled prevalence of suicidal ideation was 15.4% (95% CI 10.0-21.7; n = 18 studies) vs. 11.5% (0.4-33.3; n = 4), respectively, and suicide attempts 3.5% (1.3-6.7; n = 8) vs. 2.0% (0.0-6.4; n = 5). Prevalence of suicide deaths ranged from 0.04% to 4.4% among youth with T1D. Difficulties with T1D self-management were frequently reported to be associated with higher rates of suicide-related behaviors. However, findings on the association of glycemic levels and suicide-related behaviors were inconsistent. LIMITATIONS: There was a considerable level of heterogeneity in meta-analysis of both suicidal ideation and suicide attempts. CONCLUSIONS: Suicidal ideation and suicide attempts are prevalent in AYA with T1D. Current evidence does not suggest that these rates are higher among AYA with T1D than rates among those without.

Online Educational Resources for Youth Living With Type 1 Diabetes Transitioning to Adult Care: An Environmental Scan of Canadian Content.

OBJECTIVES: There are many educational resources for adolescents and young adults living with type 1 diabetes; however, it is unknown whether they address the breadth of topics related to transition to adult care. Our aim in this study was to collect educational resources relevant to Canadian youth and assess their quality and comprehensiveness in addressing the knowledge necessary for youth to prepare for interdependent management of their diabetes. METHODS: We conducted an environmental scan, a systematic assessment and analysis, of online education resources in English and French relevant to Canadian youth living with type 1 diabetes. Resources were screened using an open education resource evaluation grid and relevant resources were mapped to the Readiness for Emerging Adults with Diabetes Diagnosed in Youth, a validated diabetes transition readiness assessment tool. RESULTS: From 44 different sources, 1,245 resources were identified and, of these, 760 were retained for analysis. The majority were webpages (50.1%) and downloadable PDFs (42.4%), and 12.1% were interactive. Most resources covered Diabetes Knowledge (46.0%), Health Behaviour (23.8%), Insulin and Insulin Pump Management (11.8% and 8.6%, respectively), and Health-care System Navigation (9.7%). Topic areas with the fewest resources were disability accommodations (n=5), sexual health/function (n=4), and locating trustworthy diabetes resources (n=3). CONCLUSIONS: There are many resources available for those living with type 1 diabetes preparing to transition to adult care, with the majority pertaining to diabetes knowledge and the least for navigation of the health system. Few resources were available on the topics of substance use, sexual health, and reproductive health. An interactive presentation of these resources, as well as a central repository to house these resources, would improve access for youth and diabetes care providers during transition preparation.

Detection of hypertension and prehypertension in paediatric patients with type 1 diabetes using a simple blood pressure table.

BACKGROUND: The diagnosis of hypertension is often unrecognized in the general paediatric and type 1 diabetes populations. Reference to a simple blood pressure table has been proposed as a screening tool for the identification of abnormal paediatric blood pressure. This simple table lists one cut-off blood pressure value for each sex and year of age, compared with the standard blood pressure tables, which list 476 abnormal and normal blood pressure values. OBJECTIVE: To determine the sensitivity and specificity of the simple blood pressure table in identifying hypertensive and abnormal (hypertensive or prehypertensive) blood pressure values in children with type 1 diabetes. METHODS: A retrospective cohort study was conducted. Data regarding baseline characteristics and blood pressure measurements were collected. Blood pressure values were categorized as nonhypertensive, prehypertensive or hypertensive using the standard and simple blood pressure tables. Sensitivity and specificity of the simple blood pressure table was determined for the identification of hypertensive and abnormal (hypertensive or prehypertensive) blood pressure values using a generalized estimating equation approach. RESULTS: The simple blood pressure table had sensitivities of 100% (95% CI 95.7% to 100%) and 100% (95% CI 97.6% to 100%), and specificities of 61.1% (95% CI 54.0% to 67.8%) and 81.3% (95% CI 74.4% to 86.6%), for the identification of hypertensive and abnormal blood pressure values, respectively. CONCLUSION: The simple blood pressure table is an effective screening tool that may enable earlier detection and timely treatment of abnormal blood pressure.

HISTORIQUE: Le diagnostic d'hypertension demeure souvent non diagnostiqué dans les populations générale et atteinte du diabète de type 1 d'âge pédiatrique. On a proposé d'utiliser un tableau simplifié de la tension artérielle comme outil de dépistage d'une tension artérielle anormale en pédiatrie. Ce tableau simplifié indique une valeur seuil de tension artérielle selon le sexe et l'âge, par rapport aux tableaux de tension artérielle standards, qui contiennent 476 valeurs de tension artérielle anormales et normales. OBJECTIF: Déterminer la sensibilité et la spécificité du tableau simplifié de la tension artérielle pour déterminer les valeurs hypertensives et anormales (hypertension et préhypertension) de la tension artérielle chez des enfants atteints du diabète de type 1. MÉTHODOLOGIE: Les chercheurs ont mené une étude rétrospective de cohorte. Ils ont amassé des données relatives aux caractéristiques et aux mesures de tension artérielle de base. Ils ont classé les valeurs de tension artérielle entre non hypertensives, préhypertensives ou hypertensives au moyen des tableaux de la tension artérielle standard et simplifié. Ils ont déterminé la sensibilité et la spécificité du tableau simplifié de la tension artérielle pour déterminer les valeurs hypertensives et anormales (hypertension ou préhypertension) de la tension artérielle au moyen d'une approche d'équations d'estimation généralisées. RÉSULTATS: Le tableau simplifié de la tension artérielle présente une sensibilité de 100 % (95 % IC 95,7 % à 100 %) et de 100 % (95 % IC 97,6 % à 100 %), et une spécificité de 61,1 % (95 % IC 54,0 % à 67,8 %) et de 81,3 % (95 % IC 74,4 % à 86,6 %) pour déterminer des valeurs de tension artérielle hypertensives et anormales, respectivement. CONCLUSION: Le tableau simplifié de la tension artérielle est un outil de dépistage efficace qui peut favoriser un dépistage plus rapide et un traitement opportun de la tension artérielle anormale.

Considering gestational diabetes and gestational hypertension history across two pregnancies in relationship to cardiovascular disease development: A retrospective cohort study.

AIMS: Gestational diabetes (GDM) and hypertension (GHTN) occurrences signal elevated cardiovascular disease (CVD) risk. There is little study of occurrence and recurrence of these conditions in relationship to CVD. Among women with two singleton pregnancies, we aimed to quantify CVD risk in relationship to the number of GDM/GHTN occurrences. METHODS: In this Quebec-based retrospective cohort study (n = 431,980), we ascertained the number of GDM/GHTN occurrences over two pregnancies and assessed for CVD over a median of 16.4 years (cohort inception 1990-2012, outcomes 1990-2019). We defined CVD as a composite of myocardial infarction, stroke, and angina, requiring hospitalization and/or causing death. We adjusted Cox proportional hazards models for offspring size, preterm/term birth status, maternal age group, time between deliveries, ethnicity, deprivation level, and co-morbid conditions. RESULTS: Compared to absence of GDM/GHTN in either pregnancy, one GDM/GHTN occurrence increased CVD hazards by 47% (hazard ratio [HR] = 1.47, 95% confidence interval [CI] 1.35-1.61), two occurrences nearly doubled hazards (HR = 1.91, 95% CI 1.68-2.17), and three or more approximately tripled CVD hazards (HR = 2.93, 95% CI 2.20-3.90). Individual components of the composite demonstrated similar findings. CONCLUSIONS: Health care providers and mothers should consider a complete history of GDM/GHTN occurrences to ascertain the importance and urgency of preventive action.

Socioeconomic Disparities in Glycemic Management in Children and Youth With Type 1 Diabetes: A Retrospective Cohort Study.

OBJECTIVE: In Canada, few studies have addressed health inequalities in type 1 diabetes (T1D) outcomes. In this study, we examined the relationship between socioeconomic status (SES) and glycemic management in children with T1D and determine whether technology use (insulin pumps or continuous glucose monitoring [CGM]), diabetes-related physician visits, and depressive symptoms modified the association. METHODS: This work was a retrospective cohort study using the Montréal Children's Hospital Pediatric Diabetes Database of children 0 to 18 years old, diagnosed with T1D for ≥1 year, and with a hospital visit between November 2019 and October 2020. Main exposure was SES measured by the Material and Social Deprivation Index (least, moderately, or most deprived). We determined the association between SES and mean glycated hemoglobin (A1C; main outcome) in the year after the index visit using multivariable linear regression, adjusting for age, sex, diabetes duration, technology use, diabetes-related physician visits, and depressive symptoms (subgroup). We examined interaction terms for technology use, diabetes-related physician visits, and depressive symptoms. RESULTS: The study cohort included 306 children (mean age 13.6 years, mean A1C 8.5%). Children in the most-deprived compared with least-deprived quintiles had higher mean A1C; effect modification was significant with CGM only. Children not using CGM in the most-deprived compared with least-deprived quintiles had higher mean A1C (0.52%; 95% confidence interval, 0.14% to 0.86%), whereas the association was not significant for children using CGM. CONCLUSIONS: Lower SES was associated with higher A1C; these disparities were not observed among CGM users. Further research is required to determine strategies to promote CGM access among children of lower SES in the Canadian health-care context.

Associations of Diabetes-related and Health-related Quality of Life With Glycemic Levels in Adolescents With Type 1 Diabetes Preparing to Transition to Adult Care.

OBJECTIVES: As adolescents with type 1 diabetes (T1D) progress to adulthood, they assume responsibility for diabetes self-management while dealing with competing life demands, decreasing parental support, and the transfer to adult care. Lower perceived quality of life (QOL) may hamper diabetes management, which is associated with suboptimal glycemic levels. Our objective was to determine associations of diabetes- and health-related QOL with glycemic management (glycated hemoglobin [A1C]) in adolescents with T1D before their transfer to adult care. METHODS: We conducted a cross-sectional analysis of baseline data from the Group Education Trial to Improve Transition (GET-IT- T1D) in adolescents with T1D (16 to 17 years of age). Participants completed validated questionnaires measuring diabetes-related QOL (PedsQL 3.2 Diabetes Module) and health-related QOL (PedsQL 4.0 Generic Core Scales). Associations of QOL Total and subscale scores with A1C were assessed using linear regression models adjusted for sex, diabetes duration, socioeconomic status, insulin pump use, and mental health comorbidity. RESULTS: One hundred fifty-three adolescents with T1D were included (mean age, 16.5 [standard deviation, 0.3] years). Diabetes-related QOL Total scores (adjusted ß=-0.04; 95% confidence interval [CI], -0.05 to -0.02) as well as subscale scores for Diabetes Symptoms (adjusted ß=-0.02; 95% CI, -0.04 to -0.00) and Diabetes Management (adjusted ß=-0.04; 95% CI, -0.05 to -0.02) were inversely associated with A1C. Health-related QOL Total scores were not associated with A1C, but Psychosocial Health subscale scores were (adjusted ß=-0.01; 95% CI, -0.03 to -0.00). CONCLUSION: Our results suggest that strategies focussing on diabetes-related QOL and psychosocial health may help prepare adolescents for the increasing responsibility of diabetes self-care.

Adaptation of an Adult Web Application for Type 1 Diabetes Self-management to Youth Using the Behavior Change Wheel to Tailor the Needs of Health Care Transition: Qualitative Interview Study.

BACKGROUND: Youth (aged 14-24 years) living with type 1 diabetes (T1D) encounter increased challenges in their diabetes self-management (DSM), especially during the transition to adult care. Although DSM education and support are imperative, there is insufficient information on how web-based digital tools tailored to their demands can be developed. OBJECTIVE: On the basis of the Behavior Change Wheel, this study aims to identify, among youth living with T1D, the needs and factors influencing their DSM in the context of health care transition and to inform the adaptation (content and features) of an adult self-guided web application (Support). METHODS: Internet-based semistructured individual interviews based on a phenomenological study design were conducted with 21 youths, and transcripts were analyzed using an inductive approach with concept mapping. RESULTS: Factors influencing T1D self-management were categorized into barriers and facilitators and then as external or internal. Features influencing the accessibility to information, increasing the sense of support, and use of the tool were positively accepted. Features unrelated to their expectations of digital tool use or difficulty navigating were viewed negatively. Participants expressed an interest in reliable, practical, and novel educational content. Although youth considered the information provided by medical professionals to be important, peer exchange was deemed necessary to obtain a practical perspective and real-life examples. CONCLUSIONS: Compared with the adult population, in addition to tailored content and a simplified information search process, when building a DSM education and support digital tool for youth, features should be selected to encourage supervised peer exchange.

Qualitative study exploring the perspectives of emerging adults with type 1 diabetes after transfer to adult care from a paediatric diabetes centre in Montreal, Canada.

INTRODUCTION: Among youth living with type 1 diabetes (T1D), the increasing demands to diabetes self-care and medical follow-up during the transition from paediatric to adult care has been associated with greater morbidity and mortality. Inadequate healthcare support for youth during the transition care period could exacerbate psychosocial risks and difficulties that are common during emerging adulthood. The current investigation sought to explore the post-transfer perceptions of emerging adults living with T1D relating to their transition to adult care. RESEARCH DESIGN AND METHODS: Thirty-three emerging adults living with T1D were recruited during paediatric care and contacted for a semistructured interview post-transfer to adult care (16.2±4.2 months post-transfer) in Montreal, Canada. We analysed data using thematic analysis. RESULTS: We identified four key themes: (1) varied perceptions of the transition process from being quick and abrupt with minimal advice or information from paediatric healthcare providers (HCP) to more positive including a greater motivation for self-management and the transition being concurrent with the developmental period; (2) facilitators to the transition process included informational and tangible social support from HCPs and family or friends, a positive relationship with adult HCP and a greater ease in communicating with the adult care clinic or adult HCP; (3) barriers to adequate transition included lack of advice or information from paediatric HCPs, loss of support from HCPs and friends or family, the separation of healthcare services and greater difficulty in making appointments with adult clinic or HCP and (4) participants recommendations for improving the transition included increasing the length and frequency of appointments in adult care, having access to educational information, and better transition preparation from paediatric HCPs. CONCLUSIONS: The experiences and perceptions of emerging adults are invaluable to guide the ongoing development and improvement of transition programmes for childhood-onset chronic illnesses.

Understanding Whether and How a Digital Health Intervention Improves Transition Care for Emerging Adults Living With Type 1 Diabetes: Protocol for a Mixed Methods Realist Evaluation.

BACKGROUND: Emerging adults living with type 1 diabetes (T1D) face a series of challenges with self-management and decreased health system engagement, leading to an increased risk of acute complications and hospital admissions. Effective and scalable strategies are needed to support this population to transfer seamlessly from pediatric to adult care with sufficient self-management capability. While digital health interventions for T1D self-management are a promising strategy, it remains unclear which elements work, how, and for which groups of individuals. OBJECTIVE: This study aims to evaluate the design and implementation of a multicomponent SMS text message-based digital health intervention to support emerging adults living with T1D in real-world settings. The objectives are to identify the intervention components and associated mechanisms that support user engagement and T1D health care transition experiences and determine the individual characteristics that influence the implementation process. METHODS: We used a realist evaluation embedded alongside a randomized controlled trial, which uses a sequential mixed methods design to analyze data from multiple sources, including intervention usage data, patient-reported outcomes, and realist interviews. In step 1, we conducted a document analysis to develop a program theory that outlines the hypothesized relationships among "individual-level contextual factors, intervention components and features, mechanisms, and outcomes," with special attention paid to user engagement. Among them, intervention components and features depict 10 core characteristics such as transition support information, problem-solving information, and real-time interactivity. The proximal outcomes of interest include user engagement, self-efficacy, and negative emotions, whereas the distal outcomes of interest include transition readiness, self-blood glucose monitoring behaviors, and blood glucose. In step 2, we plan to conduct semistructured realist interviews with the randomized controlled trial's intervention-arm participants to test the hypothesized "context-intervention-mechanism-outcome" configurations. In step 3, we plan to triangulate all sources of data using a coincidence analysis to identify the necessary combinations of factors that determine whether and how the desired outcomes are achieved and use these insights to consolidate the program theory. RESULTS: For step 1 analysis, we have developed the initial program theory and the corresponding data collection plan. For step 2 analysis, participant enrollment for the randomized controlled trial started in January 2023. Participant enrollment for this realist evaluation was anticipated to start in July 2023 and continue until we reached thematic saturation or achieved informational power. CONCLUSIONS: Beyond contributing to knowledge on the multiple pathways that lead to successful engagement with a digital health intervention as well as target outcomes in T1D care transitions, embedding the realist evaluation alongside the trial may inform real-time intervention refinement to improve user engagement and transition experiences. The knowledge gained from this study may inform the design, implementation, and evaluation of future digital health interventions that aim to improve transition experiences.

Text message-based intervention, Keeping in Touch (KiT), to support youth as they transition to adult type 1 diabetes care: a protocol for a multisite randomised controlled superiority trial.

INTRODUCTION: Transition from paediatric to adult care can be challenging for youth living with type 1 diabetes (T1D), as many youth feel unprepared to transfer to adult care and are at high risk for deterioration of glycaemic management and acute complications. Existing strategies to improve transition experience and outcomes are limited by cost, scalability, generalisability and youth engagement. Text messaging is an acceptable, accessible and cost-effective way of engaging youth. Together with adolescents and emerging adults and paediatric and adult T1D providers, we co-designed a text message-based intervention, Keeping in Touch (KiT), to deliver tailored transition support. Our primary objective is to test the effectiveness of KiT on diabetes self-efficacy in a randomised controlled trial. METHODS AND ANALYSIS: We will randomise 183 adolescents with T1D aged 17-18 years within 4 months of their final paediatric diabetes visit to the intervention or usual care. KiT will deliver tailored T1D transition support via text messages over 12 months based on a transition readiness assessment. The primary outcome, self-efficacy for diabetes self-management, will be measured 12 months after enrolment. Secondary outcomes, measured at 6 and 12 months, include transition readiness, perceived T1D-related stigma, time between final paediatric and first adult diabetes visits, haemoglobin A1c, and other glycaemia measures (for continuous glucose monitor users), diabetes-related hospitalisations and emergency department visits and the cost of implementing the intervention. The analysis will be intention-to-treat comparing diabetes self-efficacy at 12 months between groups. A process evaluation will be conducted to identify elements of the intervention and individual-level factors influencing implementation and outcomes. ETHICS AND DISSEMINATION: The study protocol version 7 July 2022 and accompanying documents were approved by Clinical Trials Ontario (Project ID: 3986) and the McGill University Health Centre (MP-37-2023-8823). Study findings will be presented at scientific conferences and in peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT05434754.
