Insulin management and metabolic control of type 1 diabetes mellitus in childhood and adolescence in 18 countries. Hvidøre Study Group on Childhood Diabetes

Nanoparticle oral absorption and its clinical translational potential

Oral administration of pharmaceuticals is the most preferred route of administration for patients, but it is challenging to effectively deliver active ingredients (APIs) that i) have extremely high or low solubility in intestinal fluids, ii) are large in size, iii) are subject to digestive and/or metabolic enzymes present in the gastrointestinal tract (GIT), brush border, and liver, and iv) are P-glycoprotein substrates. Over the past decades, efforts to increase the oral bioavailability of APIs have led to the development of nanoparticles (NPs) with non-specific uptake pathways (M cells, mucosal, and tight junctions) and target-specific uptake pathways (FcRn, vitamin B12, and bile acids). However, voluminous findings from preclinical models of different species rarely meet practical standards when translated to humans, and API concentrations in NPs are not within the adequate therapeutic window. Various NP oral delivery approaches studied so far show varying bioavailability impacted by a range of factors, such as species, GIT physiology, age, and disease state. This may cause difficulty in obtaining similar oral delivery efficacy when research results in animal models are translated into humans. This review describes the selection of parameters to be considered for translational potential when designing and developing oral NPs.

Comparison of regular with NPH insulin vs. premix insulin in children and adolescents with type 1 diabetes in a resources-limited setting: a retrospective data analysis

OBJECTIVES

Few studies addressed the efficacy of human insulin regimens (mostly premix insulin) used in many low-and-middle income countries on glycemic control of children and adolescents with diabetes. The aim of this study was to assess the efficacy of the premix insulin on the glycated hemoglobin (HbA_1c) in comparison to the regular with NPH insulin scheme.

METHODS

A retrospective study was carried out from January 2020 to September 2022 on patients with type 1 diabetes aged below 18 years followed in Burkina Life For A Child program. They were categorized into three groups, on regular with NPH insulin (Group A), on premix insulin (Group B) and on regular with premix insulin (Group C). Outcome was analyzed based on HbA_1c level.

RESULTS

Sixty-eight patients with a mean age of 15.38 ± 2.26 years and the sex ratio (M/W) 0.94 were studied. There were 14 in Group A, 20 in Group B, and 34 patients in Group C. The mean HbA_1c value in the corresponding insulin regimen was 12.8 ± 1.39%, 9.87 ± 2.18%, and 10.66 ± 2.1%, respectively. Glycemic control was better in Groups B and C than Group A (p<0.05) but there was no difference between groups B and C.

CONCLUSIONS

Our results indicate that the use of premix insulin gives a better glycemic control than NPH insulin. However, further prospective study of these insulin regimens with a strengthening education strategy and glycemic control by continuous glucose monitoring and HbA_1c is required to corroborate these preliminary findings.

The relationship between well-being and HbA1c in adults with type 1 diabetes: A systematic review

BACKGROUND

Diabetes has been associated with psychological problems, which in turn have been related to poorer glycemic control (glycosylated hemoglobin [HbA1c]). On the contrary, psychological well-being constructs have been associated with superior medical outcomes, including better HbA1c.

AIM

The main objective of this study was to systematically review the existing literature about the relationships between subjective well-being (SWB) and HbA1c in adults with type 1 diabetes (T1D).

METHODS

Comprehensive searches were conducted in PubMed, Scopus, and Medline, time restricted to 2021, for studies examining the link between HbA1c and the cognitive (CWB) and affective (AWB) components of SWB. A total of 16 eligible studies were selected according to the inclusion criteria, of which 15 measured CWB and 1 AWB.

RESULTS

Of the 15 studies included, 11 showed a relationship between CWB and HbA1c, with a higher level of HbA1c being related to poorer CWB. The other four studies did not find any significant association. Finally, the only study examining the relationship between AWB and HbA1c found a marginally association between these variables in the expected direction.

CONCLUSION

The overall data suggest that CWB is negatively related to HbA1c in this population, but these results are inconclusive. This systematic review offers clinical implications, such as the possible evaluation, prevention, and treatment of the problems associated with diabetes through the study and training of the psychosocial variables that may directly influence SWB. Limitations and future lines of investigation are discussed.

Latent classifications of parental involvement in diabetes management for youth with type 1 diabetes: A randomized clinical trial

OBJECTIVE

Understanding how parent-child relationships influence diabetes management in youth with type 1 diabetes is critical for minimizing the risk of short- and long-term complications. We examined how classes of diabetes-specific parenting behaviors are associated with disease management and well-being for youth with type 1 diabetes.

RESEARCH DESIGN AND METHODS

The Family Management of Diabetes clinical trial tested the efficacy of a 2-year behavioral intervention for families of youth with type 1 diabetes. Three hundred and ninety youth diagnosed with type 1 diabetes and their primary caregiver were recruited from four pediatric endocrinology centers in the US Classifications of parental involvement utilized baseline parent and youth reports of task involvement, collaborative involvement, and parent-youth conflict. Class differences in baseline glycemic control (HbA1c), regimen adherence, general and diabetes quality of life, and depressive symptoms, and 2-year change in HbA1c were examined.

RESULTS

Latent profile analysis identified three classes: (1) high in task and collaborative involvement, low in conflict (Harmonious), (2) low in task involvement, collaborative involvement, and conflict (Indifferent), (3) high in task involvement and conflict, low in collaborative involvement (Inharmonious). The Harmonious group demonstrated the best adherence, glycemic control, and psychosocial well-being. The Inharmonious and Indifferent groups had similar diabetes management, but youth from Inharmonious families showed poorer psychosocial well-being. The intervention effect on glycemic control did not differ across the classes.

CONCLUSIONS

The interplay of parental involvement and conflict resulted in distinct parenting classes that differed in disease management and well-being. However, the classes benefitted similarly from the behavioral intervention.

The Potential of Current Noninvasive Wearable Technology for the Monitoring of Physiological Signals in the Management of Type 1 Diabetes: Literature Survey

Background

Monitoring glucose and other parameters in persons with type 1 diabetes (T1D) can enhance acute glycemic management and the diagnosis of long-term complications of the disease. For most persons living with T1D, the determination of insulin delivery is based on a single measured parameter—glucose. To date, wearable sensors exist that enable the seamless, noninvasive, and low-cost monitoring of multiple physiological parameters.

Objective

The objective of this literature survey is to explore whether some of the physiological parameters that can be monitored with noninvasive, wearable sensors may be used to enhance T1D management.

Methods

A list of physiological parameters, which can be monitored by using wearable sensors available in 2020, was compiled by a thorough review of the devices available in the market. A literature survey was performed using search terms related to T1D combined with the identified physiological parameters. The selected publications were restricted to human studies, which had at least their abstracts available. The PubMed and Scopus databases were interrogated. In total, 77 articles were retained and analyzed based on the following two axes: the reported relations between these parameters and T1D, which were found by comparing persons with T1D and healthy control participants, and the potential areas for T1D enhancement via the further analysis of the found relationships in studies working within T1D cohorts.

Results

On the basis of our search methodology, 626 articles were returned, and after applying our exclusion criteria, 77 (12.3%) articles were retained. Physiological parameters with potential for monitoring by using noninvasive wearable devices in persons with T1D included those related to cardiac autonomic function, cardiorespiratory control balance and fitness, sudomotor function, and skin temperature. Cardiac autonomic function measures, particularly the indices of heart rate and heart rate variability, have been shown to be valuable in diagnosing and monitoring cardiac autonomic neuropathy and, potentially, predicting and detecting hypoglycemia. All identified physiological parameters were shown to be associated with some aspects of diabetes complications, such as retinopathy, neuropathy, and nephropathy, as well as macrovascular disease, with capacity for early risk prediction. However, although they can be monitored by available wearable sensors, most studies have yet to adopt them, as opposed to using more conventional devices.

Conclusions

Wearable sensors have the potential to augment T1D sensing with additional, informative biomarkers, which can be monitored noninvasively, seamlessly, and continuously. However, significant challenges associated with measurement accuracy, removal of noise and motion artifacts, and smart decision-making exist. Consequently, research should focus on harvesting the information hidden in the complex data generated by wearable sensors and on developing models and smart decision strategies to optimize the incorporation of these novel inputs into T1D interventions.

Improving access to diabetes care for children: An evaluation of the changing diabetes in children project in Kenya and Bangladesh

BACKGROUND

The changing diabetes in children (CDiC) project is a public-private partnership implemented by Novo Nordisk, to improve access to diabetes care for children with type 1 diabetes. This paper outlines the findings from an evaluation of CDiC in Bangladesh and Kenya, assessing whether CDiC has achieved its objectives in each of six core program components.

RESEARCH DESIGN AND METHODS

The Rapid Assessment Protocol for Insulin Access (RAPIA) framework was used to analyze the path of insulin provision and the healthcare infrastructure in place for diagnosis and treatment of diabetes. The RAPIA facilitates a mixed-methods approach to multiple levels of data collection and systems analysis. Information is collected through questionnaires, in-depth interviews and focus group discussions, site visits, and document reviews, engaging a wide range of stakeholders (N = 127). All transcripts were analyzed thematically.

RESULTS

The CDiC scheme provides a stable supply of free insulin to children in implementing facilities in Kenya and Bangladesh, and offers a comprehensive package of pediatric diabetes care. However, some elements of the CDiC program were not functioning as originally intended. Transitions away from donor funding and toward government ownership are a particular concern, as patients may incur additional treatment costs, while services offered may be reduced. Additionally, despite subsidized treatment costs, indirect costs remain a substantial barrier to care.

CONCLUSION

Public-private partnerships such as the CDiC program can improve access to life-saving medicines. However, our analysis found several limitations, including concerns over the sustainability of the project in both countries. Any program reliant on external funding and delivered in a high-turnover staffing environment will be vulnerable to sustainability concerns.

Sex differences over time for glycemic control, pump use and insulin dose in patients aged 10-40 years with type 1 diabetes: a diabetes registry study

INTRODUCTION

To evaluate sex differences in people with type 1 diabetes concerning changes in glycemic control and trends in insulin pump use and insulin dose over two decades in adolescents and one-and-a-half decades in adults.

RESEARCH DESIGN AND METHODS

People aged 10-20 years (data years 1999-2018) and 21-40 years (data years 2004-2018) with type 1 diabetes were identified in the Diabetes Prospective Follow-up Registry (DPV). All available patients' data sets of the respective period were used for linear regression analyses to investigate trends in HbA1c, pump use, insulin doses and body mass index SD scores (BMI-SDS) in females and males. In addition, stratification by migrant background was made for the adolescent group.

RESULTS

In the youth group (n=68 662), both boys and girls showed an HbA1c decrease over the period examined. After stratification for migrant background, an HbA1c convergence between boys and girls was seen in those without migrant background as of 2016. Usage of insulin pumps increased continuously from 3% (boys and girls) to 47% (boys) and 54% (girls), respectively. The daily insulin dose in units per kilogram body weight and day increased continuously from 1999 to 2018. An insulin dose leveling between boys and girls occurred. BMI-SDS consistently increased in girls whereas only slight variations were observed in boys.The adult group (n=15 380) showed constant HbA1c sex differences from 2004 to 2018 with lower HbA1c level in females. The use of insulin pump therapy rose from 18% to 35% (males) and 30% to 50% (females).

CONCLUSIONS

The gap in metabolic control between boys and girls with type 1 diabetes seems to close, but predominantly in adolescents without a migrant background. Improved HbA1c was associated with increased insulin pump use, especially in girls.In adult patients, sex differences in metabolic control and insulin pump use persist: women show constantly lower HbA1c values and higher insulin pump use.

Non-Insulin Antidiabetes Treatment in Type 1 Diabetes Mellitus: A Systematic Review and Meta-Analysis

In order to evaluate the efficacy and side effects of the non-insulin antidiabetes medications as an adjunct treatment in type 1 diabetes mellitus (T1DM), we conducted systematic searches in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials for randomized controlled trials published between the date of inception and March 2020 to produce a systematic review and meta-analysis. Overall, 57 studies were included. Compared with placebo, antidiabetes agents in adjunct to insulin treatment resulted in significant reduction in glycosylated hemoglobin (weighted mean difference [WMD], -0.30%; 95% confidence interval [CI], -0.34 to -0.25%; P<0.01) and body weight (WMD, -2.15 kg; 95% CI, -2.77 to -1.53 kg; P<0.01), and required a significantly lower dosage of insulin (WMD, -5.17 unit/day; 95% CI, -6.77 to -3.57 unit/day; P<0.01). Compared with placebo, antidiabetes agents in adjunct to insulin treatment increased the risk of hypoglycemia (relative risk [RR], 1.04; 95% CI, 1.01 to 1.08; P=0.02) and gastrointestinal side effects (RR, 1.99; 95% CI, 1.61 to 2.46; P<0.01) in patients with T1DM. Compared with placebo, the use of non-insulin antidiabetes agents in addition to insulin could lead to glycemic improvement, weight control and lower insulin dosage, while they might be associated with increased risks of hypoglycemia and gastrointestinal side effects in patients with T1DM.

Transition of Youth With Type 2 Diabetes: Predictors of Health-Care Utilization After Transition to Adult Care From Population-Based Administrative Data

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<0.01]; posttransition: 1.6 vs 2.1 visits/person year [p<0.01]). Accounting for sex, geography, age, education, socioeconomic status and diabetes type, achieving 4 visits in 2 years posttransition was predicted by the number of visits pretransition (odds ratio, 1.35; 95% confidence interval, 1.23 to 1.49) and diabetes type (type 2 diabetes: odds ratio, 0.57; 95% confidence interval, 0.34 to 0.98).

CONCLUSIONS

Youth with type 2 diabetes attend fewer medical follow-up visits pre- and posttransition to adult care compared to youth with type 1 diabetes. Focused, informed, specific transition planning is needed that addresses the unique characteristics of this population.

Diabetes distress in Indian children with type 1 diabetes mellitus and their mothers

BACKGROUND

Children and their mothers, who are usually the primary caregivers, are likely to be distressed due to type 1 diabetes (T1DM).

OBJECTIVES

(1) To assess diabetes-specific distress (DD) perceived by children and adolescents with T1DM and their mothers and association of distress between children and mothers. (2) To study the association of diabetes distress with glycemic control and disease duration.

SUBJECTS

Children and adolescents with T1DM over eight years and their mothers.

METHODS

Clinical data were recorded. DD was assessed by Problem Associated in Diabetes-Pediatric (PAID-Peds) (range 0-80) and Problem Associated in Diabetes-Parents Revised (PAID-PR) (range 0-72) questionnaires (higher scores indicate higher distress); administered to children and mothers, respectively. Sub-dimensions in questionnaires included diabetes-related emotional problems, and treatment-, food-, and social support-related problems. Correlation analysis (Spearman's) was performed, and a paired t-test was used to compare PAID-Peds and PAID-PR (SPSS 25).

RESULTS

Mean PAID-Peds and PAID-PR scores in 67 children and mothers were 24.4 ± 18.1 and 31.9 ± 21.5, respectively (p=0.009), and a significant correlation was noted between their scores (R=0.45, p=0.001). PAID-Peds score was positively associated with HbA1c (R=0.25, p=0.04). Diabetes-related emotional problems of mothers and children (R=0.38, p=0.003), treatment problems (R=0.5, p=0.001), and food problems (R=0.24, p=0.05) correlated positively. Subdimension scores were significantly different in children and mothers except in the social support domain.

CONCLUSION

DD was higher in mothers than children; higher distress in children was associated with poor metabolic control. Evaluation of DD needs to be performed in children with T1DM.

Depression and parenting in youth with type 1 diabetes: Are general and diabetes-specific parenting behaviors associated with depressive symptoms over a 2-year period?

To examine cross-sectional and longitudinal associations of general parenting style and diabetes-specific parenting behaviors with depression in youth with type 1 diabetes. Participants (n = 390) completed self-report measures of depression at baseline and 2-year follow-up, general parenting style at baseline, and diabetes-specific parenting (conflict, task involvement, and collaborative involvement) at baseline and every 6 months. Logistic regression examined associations of parenting with depression at baseline and 2-year follow-up. A less authoritative parenting style, lower parent collaborative involvement, and greater diabetes-related conflict were associated with baseline depression in the model simultaneously including all parenting variables and covariates. Lower parent collaborative involvement and higher diabetes-related conflict were associated with depression at 2-year follow-up, adjusting for baseline depression and covariates. Parent task involvement was not associated with depression at either time. Findings suggest a protective role of parenting in reducing the risk of depression in youth with type 1 diabetes.

Frequency of Self-Monitoring of Blood Glucose during the School Day Is Associated with the Optimal Glycemic Control among Korean Adolescents with Type 1 Diabetes

BACKGROUND

This study aimed to evaluate the relationship between the frequency of self-monitoring of blood glucose (SMBG) and glycosylated hemoglobin (HbA1c) levels among Korean adolescents with type 1 diabetes mellitus (T1DM). Factors affecting the SMBG frequency were analyzed in order to improve their glycemic control.

METHODS

Sixty-one adolescents aged 13 to 18 years with T1DM were included from one tertiary center. Clinical and biochemical variables were recorded. Factors associated with SMBG frequency were assessed using structured self-reported questionnaires.

RESULTS

Average total daily SMBG frequency was 3.8±2.1 and frequency during the school day was 1.3±1.2. The mean HbA1c level was 8.6%±1.4%. As the daily SMBG frequency increased, HbA1c levels declined (P=0.001). The adjusted odds of achieving the target HbA1c in participants who performed daily SMBG ≥5 significantly increased 9.87 folds (95% confidence interval [CI], 1.58 to 61.70) compared with those performed SMBG four times a day. In the subjects whose SMBG frequency <1/day during the school day, an 80% reduction in the adjusted odds ratio 0.2 (95% CI, 0.05 to 0.86) showed compared to the group with performing two SMBG measurements in the school setting. The number of SMBG testing performed at school was significantly high for individuals assisted by their friends (P=0.031) and for those who did SMBG in the classrooms (P=0.039).

CONCLUSION

Higher SMBG frequency was significantly associated with lower HbA1c in Korean adolescents with T1DM. It would be necessary to establish the school environments that can facilitate adequate glycemic control, including frequent SMBG.

Immense Insulin Intestinal Uptake and Lymphatic Transport Using Bile Acid Conjugated Partially Uncapped Liposome

We provide immense insulin absorption from the gastrointestinal tract, combining apical sodium-dependent bile acid transporter-mediated intestinal uptake and the lymphatic transport pathway. This strategy has proven to employ chondroitin sulfate- g-taurocholic acid coated, insulin-loaded partially uncapped liposome (IPUL-CST) for type 1 diabetes mellitus (T1DM) treatment. The loading efficiency of insulin in IPUL-CST increased significantly from 33% to 75% via the partially uncapped liposome preparation method. Moreover, the IPUL-CST revealed an improved insulin protection efficacy in GIT simulated pH and digestive enzyme conditions. The high dose of IPUL-CST in the small intestine was detected 4 h post-oral administration using ex vivo optical imaging and fluorescence intensity. The IPUL-CST exhibited significantly enhanced intestinal absorption (oral bioavailability, 34%; T_max, 9 h) and reduced blood glucose levels for 16 h in T1DM. The results demonstrated that the new investigated IPUL-CST is a promising carrier for oral insulin delivery.

A Danish version of self-efficacy in diabetes self-management: A valid and reliable questionnaire affected by age and sex

BACKGROUND

Managing the chronic illness type 1 diabetes (T1D) is extremely demanding, especially during adolescence. Self-efficacy is belief in one's own capabilities and this is crucial for diabetes management. Having a valid method for measuring self-efficacy is important.

OBJECTIVE

Our aims were to psychometrically validate a Danish version of the self-efficacy in diabetes management (SEDM) questionnaire, and to examine the relationship between background variables and self-efficacy.

METHODS

All Danish adolescents with T1D (n = 1075) were invited to participate in our study. In total, 689 agreed to participate and 602 completed the study. Data were collected using a web-based survey. All participants were asked to provide a blood sample for HbA1c measurement. Graphical log-linear Rasch modeling (GLLRM) was used to validate the questionnaire and its reliability was assessed using Monte Carlo simulation.

RESULTS

We found the questionnaire to be valid and reliable, but it had a dual structure that suggested a need for 2 separate subscales. One subscale related to practical (SEDM1) and the other to emotional (SEDM2) aspects of diabetes management. Both subscales were targeted toward adolescents with lower self-efficacy and were associated with HbA1c. SEDM1 was influenced by treatment modality and age. In SEDM2 we found an interaction between age and sex.

CONCLUSION

The Danish version of the SEDM questionnaire should be divided into two parts, each with a valid and reliable subscale for self-efficacy measurement. The relationship between self-efficacy and age seems to differ between boys and girls.

Diabetes knowledge in adolescents with type 1 diabetes and their parents and glycemic control

OBJECTIVE

To evaluate diabetes knowledge and skills (DKS) in adolescents (>10 year) with type 1 diabetes (T1D) and their parents, and its effect on glycemic control.

METHODS

A ready-to-use program and a standardized questionnaire comprising 50 true-false questions based on this program, were elaborated by a National Committee, to help dispensing education at diagnosis of T1D. The questionnaire was completed by 2933 T1D patients (49% girls, 51% boys; 14.1 ± 2.5 year), 2180 mothers and 798 fathers, in 115 pediatric centers. Associations between DKS score (number of correct answers), glycated hemoglobin (HbA1c) and sociofamilial characteristics were assessed.

RESULTS

DKS score increased with age, and was higher in girls than in boys and in mothers than in fathers; it correlated strongly between adolescents and their own parents; it was higher when adolescents had previously participated in diabetes camp and when parents had higher academic levels. HbA1c decreased significantly with parents' higher DKS score and academic level, and when both parents lived together. Mean adolescent DKS score was significantly higher in patients with HbA1c below 8% or 8.5% than for patients with HbA1c above these thresholds.

CONCLUSION

A large survey in T1D children and adolescents and their parents showed associations between DKS and glycemic control, and the major role of sociofamilial factors.

Half-Unit Insulin Pens: Disease Management in Patients With Diabetes Who Are Sensitive to Insulin

BACKGROUND

Insulin pens represent a significant technological advancement in diabetes management. While the vast majority have been designed with 1U-dosing increments, improved accuracy and precision facilitated by half-unit increments may be particularly significant in specific patients who are sensitive to insulin. These include patients with low insulin requirements and in those requiring more precise dose adjustments, such as the pediatric patient population. This review summarized functional characteristics of insulin half-unit pens (HUPs) and their effect on user experience.

METHODS

The literature search was restricted to articles published in English between January 1, 2000, and January 1, 2015. A total of 17 publications met the set criteria and were included in the review.

RESULTS

Overall, studies outlined characteristics for 4 insulin HUPs. Based on their functionality, the pens were generally similar and all met the ISO 11608-1 criteria for accuracy. However, some had specific advantageous features in terms of size, weight, design, dialing torque, and injection force. Although limited, the currently available user preference studies in children and adolescents with diabetes and their carers suggest that the selection of an HUP is likely to be influenced by a combination of factors such as these, in addition to the prescribed insulin and dosing regimen.

CONCLUSIONS

Insulin HUPs are likely to be a key diabetes management tool for patients who are sensitive to insulin; specific pen features may further advance diabetes management in these populations.

Insulin resistance, role of metformin and other non-insulin therapies in pediatric type 1 diabetes

Type 1 diabetes mellitus (T1DM) in youth is a challenging chronic medical condition. Its management should address not only the glycemic control but also insulin resistance and cardiovascular disease risk factors which are increasingly recognized to be present in youth with TID. Current knowledge on the mechanisms of insulin resistance in T1DM is reviewed. The use of adjunctive therapies that are beneficial to achieve adequate glycemic control while mitigating the effects of insulin resistance are discussed with a focus on metformin therapy and an overview of other new pharmacologic agents.

Body fat measurement in adolescent girls with type 1 diabetes: a comparison of skinfold equations against dual-energy X-ray absorptiometry

Aim

Skinfold measurement is an inexpensive and widely used technique for assessing the percentage of body fat (%BF). This study assessed the accuracy of prediction equations for %BF based on skinfold measurements compared to dual‐energy X‐ray absorptiometry (DXA) in girls with type 1 diabetes and healthy age‐matched controls.

Methods

We included 49 healthy girls and 44 girls with diabetes aged 12–19 years old, comparing the predicted %BF based on skinfold measurements and the %BF values obtained by a Lunar DPX‐L scanner. The agreement between the methods was assessed using an Bland–Altman plot.

Results

The skinfold measurements were significantly higher in girls with diabetes (p = 0.003) despite a nonsignificant difference in total %BF (p = 0.1). A significant association between bias and %BF was found for all tested equations in the Bland–Altman plots. Regression analysis showed that the association between skinfold measurements and %BF measured by DXA differed significantly (p = 0.039) between the girls with diabetes and the healthy controls.

Conclusion

The accuracy of skinfold thickness equations for assessment of %BF in adolescent girls with diabetes is poor in comparison with DXA measurements as criterion. Our findings highlight the need for the development of new prediction equations for girls with type 1 diabetes.

The IDF Life for a Child Program Index of diabetes care for children and youth

BACKGROUND AND OBJECTIVES

Care for children and youth with diabetes varies markedly around the world. We developed a standardized, reproducible measure that can be used to document and compare critical factors influencing treatment outcomes.

METHODS

A questionnaire consisting of 36 multiple-choice questions covering major components of care (such as insulin therapy, blood glucose monitoring, etc.) was sent to 75 countries: 43 under-resourced countries where the International Diabetes Federation's Life for a Child Program operates, and 32 others (mainly developed nations). Results for each country were scaled to a score with a range of 0-100.

RESULTS

Responses were received from 71 countries. Scores varied widely and were highly correlated to per capita gross domestic product (R(2) = 0.72, P < 0.001) and health expenditure (R(2) = 0.77, P < 0.001). For the 37 low- and lower-middle income countries, only two had complete government provision of human insulin and none of blood glucose test strips. Marked differences according to income were also found for access to home refrigeration; usage of insulin pens, multiple daily injections, pumps, glucagon and ketone strips; hemoglobin A1c (HbA1c) testing; and complications screening.

CONCLUSIONS

The index is a comprehensive, easily administered survey instrument. It demonstrated stark differences in access to numerous components of care necessary in achieving good outcomes for children and youth with diabetes.

Association between Responsible Pet Ownership and Glycemic Control in Youths with Type 1 Diabetes

Type 1 diabetes mellitus (T1DM) a chronic characterized by an absolute insulin deficiency requires conscientious patient self-management to maintain glucose control within a normal range. Family cohesion and adaptability, positive coping strategies, social support and adequate self-regulatory behavior are found to favorably influence glycemic control. Our hypothesis was that the responsible care of a companion animal is associated with these positive attributes and correlated with the successful management of a chronic illness such as type 1 diabetes. We recruited 223 youths between 9 and 19 years of age from the Pediatric Diabetes clinic at the University of Massachusetts Medical School, reviewed the status of their glycemic control (using three consecutive A1c values) and asked them questions about the presence of a pet at home, and their level of involvement with its care. Multivariate analyses show that children who care actively for one or more pets at home are 2.5 times more likely to have control over their glycemic levels than children who do not care for a pet, adjusting for duration of disease, socio-economic status, age and self-management [1.1 to 5.8], pWald = 0.032. A separate model involving the care of a petdog only yielded comparable results (ORa = 2.6 [1.1 to 5.9], pWald = 0.023).

Effectiveness of a structured educational intervention using psychological delivery methods in children and adolescents with poorly controlled type 1 diabetes: a cluster-randomized controlled trial of the CASCADE intervention

INTRODUCTION

Type 1 diabetes (T1D) in children and adolescents is increasing worldwide with a particular increase in children <5 years. Fewer than 1 in 6 children and adolescents achieve recommended glycated hemoglobin (HbA1c) values.

METHODS

A pragmatic, cluster-randomized controlled trial assessed the efficacy of a clinic-based structured educational group incorporating psychological approaches to improve long-term glycemic control, quality of life and psychosocial functioning in children and adolescents with T1D. 28 pediatric diabetes services were randomized to deliver the intervention or standard care. 362 children (8-16 years) with HbA1c≥8.5% were recruited. Outcomes were HbA1c at 12 and 24 months, hypoglycemia, admissions, self-management skills, intervention compliance, emotional and behavioral adjustment, and quality of life. A process evaluation collected data from key stakeholder groups in order to evaluate the feasibility of delivering the intervention.

RESULTS

298/362 patients (82.3%) provided HbA1c at 12 months and 284/362 (78.5%) at 24 months. The intervention did not improve HbA1c at 12 months (intervention effect 0.11, 95% CI -0.28 to 0.50, p=0.584), or 24 months (intervention effect 0.03, 95% CI -0.36 to 0.41, p=0.891). There were no significant changes in remaining outcomes. 96/180 (53%) families in the intervention arm attended at least 1 module. The number of modules attended did not affect outcome. Reasons for low uptake included difficulties organizing groups and work and school commitments. Those with highest HbA1cs were less likely to attend. Mean cost of the intervention was £683 per child.

CONCLUSIONS

Significant challenges in the delivery of a structured education intervention using psychological techniques to enhance engagement and behavior change delivered by diabetes nurses and dietitians in routine clinical practice were found. The intervention did not improve HbA1c in children and adolescents with poor control.

Glycemic Control in Kenyan Children and Adolescents with Type 1 Diabetes Mellitus

Background. Type 1 diabetes mellitus (T1DM) is the most common endocrine disorder in children and adolescents worldwide. While data about prevalence, treatment, and complications are recorded in many countries, few data exist for Sub-Saharan Africa. The aim of this study was to determine the degree of control in patients with T1DM aged 1-19 years over a 6-month period in 3 outpatient Kenyan clinics. It also sought to determine how control was influenced by parameters of patient and treatment. Methods. Eighty-two children and adolescents with T1DM were included in the study. Clinical history regarding duration of illness, type and dose of insulin, and recent symptoms of hypoglycemia/hyperglycemia were recorded. Glycaemia, HbA1c, and ketonuria were tested. HbA1c of 8.0% and below was defined as the cut-off for acceptable control. Results. The median HbA1c for the study population was 11.1% (range: 6.3-18.8). Overall, only 28% of patients had reasonable glycemic control as defined in this study. 72% therefore had poor control. It was also found that age above 12 years was significantly associated with poor control. Conclusions. African children and with T1DM are poorly controlled particularly in adolescents. Our data strongly support the necessity of Kenya children to receive more aggressive management and follow-up.

The Role of Dietary Protein and Fat in Glycaemic Control in Type 1 Diabetes: Implications for Intensive Diabetes Management

A primary focus of the management of type 1 diabetes has been on matching prandial insulin therapy with carbohydrate amount consumed. However, even with the introduction of more flexible intensive insulin regimes, people with type 1 diabetes still struggle to achieve optimal glycaemic control. More recently, dietary fat and protein have been recognised as having a significant impact on postprandial blood glucose levels. Fat and protein independently increase the postprandial glucose excursions and together their effect is additive. This article reviews how the fat and protein in a meal impact the postprandial glycaemic response and discusses practical approaches to managing this in clinical practice. These insights have significant implications for patient education, mealtime insulin dose calculations and dosing strategies.

Classifying insulin regimens--difficulties and proposal for comprehensive new definitions

Modern insulin regimens for the treatment of type 1 diabetes are highly individualized. The concept of an individually tailored medicine accounts for a broad variety of different insulin regimens applied. Despite clear recommendations for insulin management in children and adolescents with type 1 diabetes there is little distinctiveness about concepts and the nomenclature is confusing. Even among experts similar terms are used for different strategies. The aim of our review--based on the experiences of the Hvidoere Study Group (HSG)--is to propose comprehensive definitions for current insulin regimens reflecting current diabetes management in childhood and adolescence. The HSG--founded in 1994--is an international group representing 24 highly experienced pediatric diabetes centers, from Europe, Japan, North America and Australia. Different benchmarking studies of the HSG revealed a broad variety of insulin regimens applied in each center, respectively. Furthermore, the understanding of insulin regimens has been persistently different between the centers since more than 20 yr. Not even the terms 'conventional' and 'intensified therapy' were used consistently among all members. Besides the concepts 'conventional' and 'intensified', several other terms for the characterization of insulin regimens are in use: Basal Bolus Concept (BBC), multiple daily injections (MDI), and flexible insulin therapy (FIT) are most frequently used, although none of these expressions is clearly or consistently defined. The proposed new classification for insulin management will be comprehensive, simple, and catchy. Currently available terms were included. This classification may offer the opportunity to compare therapeutic strategies without the currently existing confusion on the insulin regimen.

Glycaemic control of Type 1 diabetes in clinical practice early in the 21st century: an international comparison

AIMS

Improving glycaemic control in people with Type 1 diabetes is known to reduce complications. Our aim was to compare glycaemic control among people with Type 1 diabetes using data gathered in regional or national registries.

METHODS

Data were obtained for children and/or adults with Type 1 diabetes from the following countries (or regions): Western Australia, Austria, Denmark, England, Champagne-Ardenne (France), Germany, Epirus, Thessaly and Thessaloniki (Greece), Galway (Ireland), several Italian regions, Latvia, Rotterdam (The Netherlands), Otago (New Zealand), Norway, Northern Ireland, Scotland, Sweden, Volyn (Ukraine), USA and Wales) from population or clinic-based registries. The sample size with available data varied from 355 to 173 880. Proportions with HbA1c < 58 mmol/mol (< 7.5%) and ≥ 75 mmol/mol (≥ 9.0%) were compared by age and sex.

RESULTS

Data were available for 324 501 people. The proportions with HbA1c 58 mmol/mol (< 7.5%) varied from 15.7% to 46.4% among 44 058 people aged < 15 years, from 8.9% to 49.5% among 50 766 people aged 15-24 years and from 20.5% to 53.6% among 229 677 people aged ≥ 25 years. Sex differences in glycaemic control were small. Proportions of people using insulin pumps varied between the 12 sources with data available.

CONCLUSION

These results suggest that there are substantial variations in glycaemic control among people with Type 1 diabetes between the data sources and that there is room for improvement in all populations, especially in young adults.

Effects of low dose metformin in adolescents with type I diabetes mellitus: a randomized, double-blinded placebo-controlled study

BACKGROUND

Insulin resistance increases during adolescence in those with type 1 diabetes mellitus (T1DM), complicating glycemic control and potentially increasing cardiovascular disease (CVD) risk. Metformin, typically used in type 2 diabetes mellitus (T2DM), is a possible adjunct therapy in T1DM to help improve glycemic control and insulin sensitivity.

OBJECTIVE

We hypothesized that metformin would improve metabolic parameters in adolescents with T1DM.

DESIGN, SETTING, AND PARTICIPANTS

This randomized, double-blinded, placebo-controlled trial included 74 pubertal adolescents (ages: 13-20 yr) with T1DM. Participants were randomized to receive either metformin or placebo for 6 months. Glycated hemoglobin (HbA1c), insulin dose, waist circumference, body mass index (BMI), and blood pressure were measured at baseline, 3 and 6 months, with fasting lipids measured at baseline and 6 months.

RESULTS

Total daily insulin dose, BMI z-score and waist circumference significantly decreased at 3 and 6 months compared to baseline within the metformin group, even among normal-weight participants. In the placebo group, total insulin dose and systolic blood pressure increased significantly at 3 months and total insulin dose increased significantly at 6 months. No significant change was observed in HbA1c at any time point between metformin and placebo groups or within either group.

CONCLUSIONS

Low-dose metformin likely improves BMI as well as insulin sensitivity in T1DM adolescents, as indicated by a decrease in total daily insulin dose. The decrease in waist circumference indicates that fat distribution is also likely impacted by metformin in T1DM. Further studies with higher metformin doses and more detailed measurements are needed to confirm these results, their underlying mechanisms, and potential impact on CVD in T1DM youth.

Digital games for type 1 and type 2 diabetes: underpinning theory with three illustrative examples

Digital games are an important class of eHealth interventions in diabetes, made possible by the Internet and a good range of affordable mobile devices (eg, mobile phones and tablets) available to consumers these days. Gamifying disease management can help children, adolescents, and adults with diabetes to better cope with their lifelong condition. Gamification and social in-game components are used to motivate players/patients and positively change their behavior and lifestyle. In this paper, we start by presenting the main challenges facing people with diabetes—children/adolescents and adults—from a clinical perspective, followed by three short illustrative examples of mobile and desktop game apps and platforms designed by Ayogo Health, Inc. (Vancouver, BC, Canada) for type 1 diabetes (one example) and type 2 diabetes (two examples). The games target different age groups with different needs—children with type 1 diabetes versus adults with type 2 diabetes. The paper is not meant to be an exhaustive review of all digital game offerings available for people with type 1 and type 2 diabetes, but rather to serve as a taster of a few of the game genres on offer today for both types of diabetes, with a brief discussion of (1) some of the underpinning psychological mechanisms of gamified digital interventions and platforms as self-management adherence tools, and more, in diabetes, and (2) some of the hypothesized potential benefits that might be gained from their routine use by people with diabetes. More research evidence from full-scale evaluation studies is needed and expected in the near future that will quantify, qualify, and establish the evidence base concerning this gamification potential, such as what works in each age group/patient type, what does not, and under which settings and criteria.

Insulin glargine in pediatric patients with type 1 diabetes in Japan

BACKGROUND

We evaluated the safety and effectiveness of insulin glargine in Japanese pediatric patients with type 1 diabetes in clinical settings based on post-marketing surveillance data.

METHODS

Clinical data were collected from Japanese pediatric patients with type 1 diabetes for 24 weeks after initiation of glargine treatment. Baseline characteristics, hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), previous/concomitant medication, height, bodyweight, and adverse events were analyzed.

RESULTS

One-hundred and thirteen patients were enrolled from 20 medical institutions in Japan in 2003 and 2004. Of these patients, 73 were included in the safety analysis, and 70 of these patients were also included in the efficacy analysis. The 73 patients included 28 boys and 45 girls, with a mean age of 11.8 years at entry. Hypoglycemia occurred in three patients (three events) and was severe in two patients (two events); all patients recovered. In the efficacy evaluation, HbA1c at baseline and final assessment was 9.10% and 8.09% (P < 0.001) in all patients; 8.96% and 7.85% (P < 0.001) in patients aged 7-12 years (Group 1); and 9.28% and 8.37% (P = 0.010) in patients aged 13-15 years (Group 2). FPG significantly decreased in all patients and in Group 1. No significant changes were observed in body mass index or degree of obesity during the study.

CONCLUSIONS

Glargine therapy for Japanese pediatric patients with type 1 diabetes resulted in good glycemic control in terms of HbA1c and FPG as well as good safety in clinical settings. Glargine had little effect on the physical build of patients.

Fibrin clot properties and haemostatic function in men and women with type 1 diabetes

The increased risk of vascular complications in type 1 diabetes may in part be explained by changes in haemostatic function. In the present study, we investigated the fibrin clot properties in patients with type 1 diabetes in relation to sex and microvascular complications. The study included 236 patients (107 women) aged between 20-70 years and without any history of cardiovascular disease. Fibrin clot properties, assessed by determination of the permeability coefficient (Ks) and turbidimetric clotting and lysis assays, did not differ between men and women. Compared with men, women had worse glycaemic control as well as higher levels of prothrombin fragment 1+2 and peak thrombin generation in vitro, indicating increased thrombin generation both in vivo and in vitro. Subgroup analyses of patients younger than 30 years revealed less permeable fibrin clots and prolonged lysis time in females compared with age-matched men. Patients with microvascular complications had higher fibrinogen concentrations and denser and less permeable fibrin clots. Thus, we conclude that in vitro fibrin clot properties in patients with type 1 diabetes without cardiovascular disease are not different between the sexes, but associate with prevalence of microvascular complications. Tighter fibrin clot formation in younger women, as suggested by our results, may affect their future cardiovascular risk and should be investigated in a larger population.

Family-based psychoeducation and Care Ambassador intervention to improve glycemic control in youth with type 1 diabetes: a randomized trial

OBJECTIVE

Youth with type 1 diabetes frequently do not achieve glycemic targets. We aimed to improve glycemic control with a Care Ambassador (CA) and family-focused psychoeducational intervention.

RESEARCH DESIGN AND METHODS

In a 2-yr, randomized, clinical trial, we compared three groups: (i) standard care, (ii) monthly outreach by a CA, and (iii) monthly outreach by a CA plus a quarterly clinic-based psychoeducational intervention. The psychoeducational intervention provided realistic expectations and problem-solving strategies related to family diabetes management. Data on diabetes management and A1c were collected, and participants completed surveys assessing parental involvement in management, diabetes-specific family conflict, and youth quality of life (QOL). The primary outcome was A1c at 2 yr; secondary outcomes included maintaining parent involvement and avoiding deterioration in glycemic control.

RESULTS

We studied 153 youth (56% female, median age 12.9 yr) with type 1 diabetes (mean A1c 8.4 ± 1.4%). There were no differences in A1c across treatment groups. Among youth with suboptimal baseline A1c ≥ 8%, more youth in the psychoeducation group maintained or improved their A1c and maintained or increased parent involvement than youth in the other two groups combined (77 vs. 52%, p = 0.03; 36 vs. 11%, p = 0.01, respectively) without negative impact on youth QOL or increased diabetes-specific family conflict.

CONCLUSIONS

No differences in A1c were detected among the three groups at 2 yr. The psychoeducational intervention was effective in maintaining or improving A1c and parent involvement in youth with suboptimal baseline glycemic control.

Predictors of self-management in pediatric type 1 diabetes: individual, family, systemic, and technologic influences

Type 1 diabetes (T1D) is a complex chronic disease that has many facets for successful management. The burden of this management falls largely on the individual and their family members. Self-management has a major influence on T1D health outcomes, and with successful management, children and adolescents with T1D can lead long and healthy lives. We discuss how various individual, family, and systemic/technologic factors influence T1D self-management, providing research that supports interventions targeting each of these factors. With this information, health care practitioners and researchers can better understand the role of T1D self-management and bolster this important aspect of T1D care.

Drug transport mechanism of oral antidiabetic nanomedicines

CONTEXT

Over the last few decades, extensive efforts have been made worldwide to develop nanomedicine delivery systems, especially via oral route for antidiabetic drugs. Absorption of insulin is hindered by epithelial cells of gastrointestinal tract, acidic gastric pH and digestive enzymes.

EVIDENCE ACQUISITION

Recent reports have identified and explained the beneficial role of several structural molecules like mucoadhesive polymers (polyacrylic acid, sodium alginate, chitosan) and other copolymers for the efficient transport and release of insulin to its receptors.

RESULTS

Insulin nanomedicines based on alginate-dextran sulfate core with a chitosan-polyethylene glycol-albumin shell reduced glycaemia in a dose dependent manner. Orally available exendin-4 formulations exerted their effects in a time dependent manner. Insulin nanoparticles formed by using alginate and dextran sulfate nucleating around calcium and binding to poloxamer, stabilized by chitosan, and subsequently coated with albumin showed a threefold increase of the hypoglycemic effect in comparison to free insulin in animal models. Solid lipid nanoparticles showed an enhancement of the bioavailability of repaglinide (RG) within optimized solid lipid nanoparticle formulations when compared with RG alone.

CONCLUSIONS

Nanoparticles represent multiparticulate delivery systems designed to obtain prolonged or controlled drug delivery and to improve bioavailability as well as stability. Nanoparticles can also offer advantages like limiting fluctuations within therapeutic range, reducing side effects, protecting drugs from degradation, decreasing dosing frequency, and improving patient compliance and convenience.

Metabolic outcomes in young children with type 1 diabetes differ between treatment centers: the Hvidoere Study in Young Children 2009

OBJECTIVE

To investigate whether center differences in glycemic control are present in prepubertal children <11 yr with type 1 diabetes mellitus.

RESEARCH DESIGN AND METHODS

This cross-sectional study involved 18 pediatric centers worldwide. All children, <11 y with a diabetes duration ≥12 months were invited to participate. Case Record Forms included information on clinical characteristics, insulin regimens, diabetic ketoacidosis (DKA), severe hypoglycemia, language difficulties, and comorbidities. Hemoglobin A1c (HbA1c) was measured centrally by liquid chromatography (DCCT aligned, range: 4.4-6.3%; IFFC: 25-45 mmol/mol).

RESULTS

A total of 1133 children participated (mean age: 8.0 ± 2.1 y; females: 47.5%, mean diabetes duration: 3.8 ± 2.1 y). HbA1c (overall mean: 8.0 ± 1.0%; range: 7.3-8.9%) and severe hypoglycemia frequency (mean 21.7 events per 100 patient-years), but not DKA, differed significantly between centers (p < 0.001 resp. p = 0.179). Language difficulties showed a negative relationship with HbA1c (8.3 ± 1.2% vs. 8.0 ± 1.0%; p = 0.036). Frequency of blood glucose monitoring demonstrated a significant but weak association with HbA1c (r = -0.17; p < 0.0001). Although significant different HbA1c levels were obtained with diverse insulin regimens (range: 7.3-8.5%; p < 0.001), center differences remained after adjusting for insulin regimen (p < 0.001). Differences between insulin regimens were no longer significant after adjusting for center effect (p = 0.199).

CONCLUSIONS

Center differences in metabolic outcomes are present in children <11 yr, irrespective of diabetes duration, age, or gender. The incidence of severe hypoglycemia is lower than in adolescents despite achieving better glycemic control. Insulin regimens show a significant relationship with HbA1c but do not explain center differences. Each center's effectiveness in using specific treatment strategies remains the key factor for outcome.

Long-term glycemic control as a result of initial education for children with new onset type 1 diabetes: does the setting matter?

PURPOSE

The purpose of this study was to examine the role of initial diabetes education delivery at an academic medical center (AMC) versus non-AMCs on long-term glycemic control.

METHODS

We performed a retrospective study of children with type 1 diabetes referred to an AMC after being educated at non-AMCs. These children were matched to a group of children diagnosed and educated as inpatients at an AMC. The A1C levels at 2, 3, and 5 years from diagnosis were compared between the 2 groups of children.

RESULTS

Records were identified from 138 children. Glycemic control was comparable in the non-AMC-educated versus AMC-educated patients at 2, 3, and 5 years from diagnosis. The A1C was also highly consistent in each patient over time.

CONCLUSIONS

Long-term glycemic control was independent of whether initial education was delivered at an AMC or non-AMC. Formal education and location at time of diagnosis do not appear to play a significant role in long-term glycemic control. Novel educational constructs, focusing on developmental stages of childhood and reeducation over time, are likely more important than education at time of diagnosis.

Assessment of psychosocial variables by parents of youth with type 1 diabetes mellitus

PURPOSE

To evaluate the impact of type 1 diabetes (T1D) on family functioning and child-rearing practices from parents' point of view, to assess parents' health-related quality of life and to explore the relations between psychosocial variables and diabetes care outcomes in youth with diabetes.

METHODS

This research was part of the cross-sectional multicenter Brazilian Type 1 Diabetes Study, conducted between December 2008 and December 2010 in 28 public clinics of 20 cities across four Brazilian geographical regions. Psychosocial questions were addressed to 1,079 parents of patients with T1D through an interview (89.3% mothers, 52.5% Caucasians, 38.6 ± 7.6 years old). Overall, 72.5% of the families were from low or very low socioeconomic levels. Parents were also submitted to health-related quality of life instruments (EQ-5D+EQ-VAS). Clinical data from the last medical appointment were collected by a physician using standardized chart review forms. The demographic, educational and socioeconomic profiles were also obtained and HbA1c levels registered.

RESULTS

Discomfort and anxiety/depression were the main complaints in EQ-5D, and were significantly more frequent in mothers (37.3% and 53.4%, respectively) than in fathers (25.7% and 32.7%, respectively). The mother was the only parent involved in diabetes care in 50.5% of the cases. The majority of parents (78.5%) mentioned changes in family functioning after the diagnosis, although they neither treated their diabetic children differently from the others (76.3%), nor set prohibitions (69.1%) due to diabetes. The majority was worried about diabetes complications (96.4%) and felt overwhelmed by diabetes care (62.8%). Parents report of overwhelming was significantly associated with anxiety/depression, as measured by the EQ-5D questionnaire. Less than half of the patients had already slept over, and the permission to do it increased as a function of children's age. Nearly half of the parents (52%) admitted to experiencing difficulties in setting limits for their children/adolescents. HbA1c levels in patients from this group (9.7 ± 2.5%) were significantly higher than those of children/adolescents whose parents reported no difficulties towards limit-setting (8.8 ± 2.1%). Parents whose children/adolescents reported the occurrence of hypoglycemic episodes in the last month complained significantly more about anxiety/depression (55.1%) than parents from patients who did not report it (45.7%). Also a significantly greater proportion of parents whose children/adolescents had been hospitalized due to hyperglycemia reported anxiety /depression (58.7%) than those whose children/adolescents had not been hospitalized (49.8%).

CONCLUSIONS

After the diagnosis of T1D, the lifestyle of all family members changes, what interferes with their quality of life. Mothers are still the primary caregivers for children/adolescents with diabetes. Difficulty to set limits for children/adolescents may be a risk for poor metabolic control. The study demonstrates the importance of family context in the adjustment of young patients to T1D. The specific needs of T1D patients and their impact on a family routine must be considered for future improvement on therapy elements and strategies.
