Improved Metabolic Control in Children and Adolescents With Type 1 Diabetes A trend analysis using prospective multicenter data from Germany and Austria

OBJECTIVE To investigate the temporal trend of metabolic control and potential predictors in German and Austrian children and adolescents with type 1 diabetes. RESEARCH DESIGN AND METHODS This study is based on a large, multicenter database for prospective longitudinal documentation of diabetes care in Germany and Austria. Data from 30,708 patients documented in 305 diabetes centers between 1995 and 2009 were analyzed. Generalized linear mixed regression models were used to adjust trend analysis for relevant confounders. RESULTS Unadjusted mean HbA1c decreased from 8.7 ± 1.8% in 1995 to 8.1 ± 1.5% in 2009. In multiple regression analysis, treatment year, age, sex, diabetes duration, migration background, BMI-SDS, and daily insulin dose were significant predictors of metabolic control (P < 0.001). After multiple adjustment, mean HbA1c decreased significantly by 0.038% per year (95% CI 0.032–0.043%), average odds ratio (OR) per year for HbA1c >7.5% (>9.0%) was 0.969 (95% CI 0.961–0.977) (0.948, 95% CI 0.941–0.956). Intensified insulin regimen was associated with lower frequency of poor metabolic control (HbA1c >9%; P = 0.005) but not with average HbA1c (P = 0.797). Rate of severe hypoglycemia and hypoglycemic coma decreased significantly (relative risk [RR] per year 0.948, 95% CI 0.918–0.979; RR 0.917, 95% CI 0.885–0.950) over the study period. Diabetic ketoacidosis rate showed no significant variation over time. CONCLUSIONS This study showed a significant improvement in metabolic control in children and adolescents with type 1 diabetes during the past decade and a simultaneous decrease in hypoglycemic events. The improvement was not completely explained by changes in the mode of insulin treatment. Other factors such as improved patient education may have accounted for the observed trend.

Health-Related Quality of Life Among German Youths With Early-Onset and Long-Duration Type 1 Diabetes

OBJECTIVE To evaluate self- and parent reports of general health status and health-related quality of life (QoL) in children and adolescents with early-onset and long-lasting type 1 diabetes compared with the general population in Germany. RESEARCH DESIGN AND METHODS A total of 629 subjects aged 11 to 17 years, with a type 1 diabetes onset occurring from age 0 to 4 years during the years 1993–1999, and their parents, completed questionnaires, including the generic KINDL-R Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents, revised version, to assess QoL. The comparison group (n = 6,813) was a representative sample from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) study. Regression analyses were conducted using sociodemographic and health-related covariates. RESULTS Intensified insulin therapy was used to treat 93% of children and adolescents with type 1 diabetes. They reported “excellent” general health as often as peers (adjusted OR 0.83 [95% CI 0.66–1.04] for an “excellent” rating), but the parent-rated general health was worse than that in the general population (OR 0.60 [0.48–0.74]). The patients reported increased self-esteem (adjusted difference β = 4.39 [SE 0.82]; P < 0.001) and well-being at school (β = 3.41 [0.77]; P < 0.001) but lower well-being within their families (β = –2.42 [0.80]; P = 0.002). The self- and parent-reported total QoL did not differ between the patient group and the general population. The adjusted difference (SE) between the two samples in total QoL was β = 0.89 (0.52; P = 0.087) in the self-reports and β = –0.98 (0.53; P = 0.066) in the parent-reports. CONCLUSIONS Compared with the general population, the QoL and general health status were not impaired among those aged 11–17 years with early-onset type 1 diabetes, despite the challenges of modern therapy.

Quality of life in intensively treated youths with early-onset type 1 diabetes: a population-based survey

To evaluate factors associated with self‐reported generic, chronic‐generic, and condition‐specific quality of life (QoL) impairments in intensively treated patients with early‐onset and long‐duration type 1 diabetes.

Lower frequency of insulin pump treatment in children and adolescents of Turkish background with type 1 diabetes: analysis of 21,497 patients in Germany.

AIM This study investigated insulin pump therapy in pediatric patients with type 1 diabetes and Turkish origin compared with those without migration background in Germany. SUBJECTS AND METHODS Using a nationwide documentation program, we estimated the prevalence of insulin pump therapy in patients < 20 years of age with Turkish origin and those without migration background. Logistic regression was used to adjust for age, sex, diabetes duration, body mass index SD score (BMI-SDS), glycated hemoglobin, number of outpatient visits, number of daily blood glucose self-measurements, and area-based socioeconomic conditions. RESULTS In 1,695 pediatric type 1 diabetes patients with Turkish background and 19,802 patients without migration background (respectively: 51.2% and 53.0% boys; mean age, 12.4 ± 4.1 and 12.6 ± 4.2 years; mean diabetes duration, 4.7 ± 3.9 and 5.3 ± 4.0 years), fully adjusted prevalences of insulin pump therapy were 18.5% and 30.9%, respectively (odds ratio 0.51, 95% confidence interval 0.43-0.60, P < 0.001). Age, sex, BMI-SDS, outpatient visits, and blood glucose self-control were significantly associated with the prevalence of insulin pump therapy but did not alter the difference substantially. CONCLUSIONS The prevalence of insulin pump therapy is roughly half among pediatric diabetes patients with Turkish background compared with those without migration background. Several covariates could not explain this difference. Individual characteristics or access barriers within the healthcare system may play a role. Further research is needed.

Associations between HbA1c and depressive symptoms in young adults with early-onset type 1 diabetes

OBJECTIVE This study sought to evaluate the associations between metabolic control and each DSM-5 (Diagnostic and Statistical Manual, fifth edition) symptom of depression among young women and men with early-onset long-duration type 1 diabetes. METHODS The data of 202 18-21-year-old patients with type 1 diabetes from a population-based, nationwide survey (40.1% male) with a mean age of 19.4 (standard deviation 0.9) years, a mean HbA1c level of 8.3% (1.6%) (i.e., 67 [17.5]mmol/mol), and a mean diabetes duration of 15.7 (1.0) years were included. The German version of the Patient Health Questionnaire (PHQ-9) was used to assess depression symptoms. For each PHQ-9 depressive symptom, the mean HbA1c values of screening-positive and screening-negative patients were compared via t-test. The associations between HbA1c levels and depressive symptoms were analyzed using multiple linear regression analyses and stepwise adjustments for individual, socioeconomic and health-related covariates. RESULTS Exactly 43.0% and 33.3% of female and male participants reported at least one depressive symptom, and 5.0% and 2.5% met the DSM-5 criteria for major depressive syndrome. HbA1c levels increased with psychomotor agitation/retardation (women), overeating/poor appetite (men/women), lethargy (men), and sleep difficulty (men). Overeating/poor appetite, lethargy, and total PHQ-9 score (per score increase by one) were associated with increased HbA1c levels of 1.10, 0.96 and 0.09 units (%), respectively. CONCLUSIONS The associations between depressive symptoms and HbA1c levels vary by symptom and sex. Differentiating the symptoms of depression and targeted interventions might help to improve metabolic outcomes in young adults with early-onset type 1 diabetes and depression.

Direct Diabetes-Related Costs in Young Patients with Early-Onset, Long-Lasting Type 1 Diabetes

Objective To estimate diabetes-related direct health care costs in pediatric patients with early-onset type 1 diabetes of long duration in Germany. Research Design and Methods Data of a population-based cohort of 1,473 subjects with type 1 diabetes onset at 0–4 years of age within the years 1993–1999 were included (mean age 13.9 (SD 2.2) years, mean diabetes duration 10.9 (SD 1.9) years, as of 31.12.2007). Diabetes-related health care services utilized in 2007 were derived from a nationwide prospective documentation system (DPV). Health care utilization was valued in monetary terms based on inpatient and outpatient medical fees and retail prices (perspective of statutory health insurance). Multiple regression models were applied to assess associations between direct diabetes-related health care costs per patient-year and demographic and clinical predictors. Results Mean direct diabetes-related health care costs per patient-year were €3,745 (inter-quartile range: 1,943–4,881). Costs for glucose self-monitoring were the main cost category (28.5%), followed by costs for continuous subcutaneous insulin infusion (25.0%), diabetes-related hospitalizations (22.1%) and insulin (18.4%). Female gender, pubertal age and poor glycemic control were associated with higher and migration background with lower total costs. Conclusions Main cost categories in patients with on average 11 years of diabetes duration were costs for glucose self-monitoring, insulin pump therapy, hospitalization and insulin. Optimization of glycemic control in particular in pubertal age through intensified care with improved diabetes education and tailored insulin regimen, can contribute to the reduction of direct diabetes-related costs in this patient group.

Impact of Maternal Country of Birth on Type-1-Diabetes Therapy and Outcome in 27,643 Children and Adolescents from the DPV Registry

Objective To study the impact of maternal country of birth on type-1-diabetes (T1D) therapy and outcome. Study Design and Methods 27,643 T1D patients aged ≤20 years with documented maternal country of birth from the multicenter German/Austrian diabetes patient registry (DPV) were analyzed. Patients were categorized based on their mother’s origin: Germany/Austria (reference), Turkey, Southern Europe, and Eastern Europe. To compare BMI standard deviation score (BMI-SDS), diabetes therapy and outcome between groups, multivariable regression was applied with adjustments for age, sex and duration of diabetes. Based on observed marginal frequencies, adjusted estimates were calculated. Linear regression was used for continuous data, logistic regression for binary data and Poisson regression for count data. All statistical analyses were performed using SAS 9.4. Significance was set at a two-tailed p<0.05. Results 83.3% of patients were offspring of native mothers. A Turkish, Southern or Eastern European background was documented in 2.4%, 1.7% and 4.3% of individuals. After demographic adjustment, patients with migration background had a higher mean BMI-SDS (Turkey, Southern Europe or Eastern Europe vs. Germany/Austria: 0.58±0.03, 0.40±0.04, or 0.37±0.02 vs. 0.31±0.01; ±SE) and a lower use of insulin pumps (26.8%, 27.9%, or 32.6% vs. 37.9%) compared to offspring of native mothers. Mean HbA1c was worst in individuals of Turkish mothers (Turkey vs. Germany/Austria: 69.7±0.7 vs. 66.6±0.1 mmol/mol; ±SE). Patients of Eastern European descent had an increased rate of severe hypoglycemia (22.09±0.13 vs. 16.13±0.02 events per 100 patient-years) and ketoacidosis was more prevalent in offspring of Turkish or Southern European mothers (7.50±0.10, or 7.13±0.11 vs. 6.54±0.02 events per 100 patient-years). Patients of Turkish descent were more often hospitalized (57.2±2.7 vs. 48.5±0.4 per 100 patient-years). All differences were significant. Conclusion The differences in diabetes therapy and outcome among patients with distinct migration background suggest that specific challenges have to be considered in clinical care.

Health Behaviour in Children and Adolescents with Type 1 Diabetes Compared to a Representative Reference Population

Objective We provide a population-based overview of health behaviours of children and adolescents with type 1 diabetes in comparison to the general population, and analyse their relevance for glycaemic control and self-rated health status. Methods Data from questionnaires of 11- to 17-year-old children and adolescents with diabetes (n = 629) were compared to a representative sample (n = 6,813). Results Children and adolescents with type 1 diabetes had a significantly increased odds of infrequent physical activity (adjusted OR 1.56), short overall duration of physical activity per week (OR 1.55, difference -1.3 hours/week), and high daily computer use (OR 2.51). They had a lower odds of active and passive smoking (OR 0.31 and OR 0.29), and high daily television time (OR 0.68). The odds of an at least good and excellent self-rated health status was increased with intense physical activity, and decreased with active smoking and prolonged daily use of computer and television. Active smoking and prolonged daily use of computer were associated with higher HbA1c. Conclusions Children and adolescents with type 1 diabetes showed a different profile of health behaviour. Their overall health may improve if their education stresses specifically frequent physical activity with longer overall duration and less frequent television or computer use.

Mental health problems among adolescents with early-onset and long-duration type 1 diabetes and their association with quality of life: a population-based survey.

Objective To evaluate mental health problems and associations between mental health problems and health-related quality of life in adolescents with type 1 diabetes in comparison with the general population. Method A total of 629 11- to 17-year-olds with early-onset and long-lasting type 1 diabetes and their parents completed comprehensive questionnaires. Mental health was assessed using the parent- and self-report versions of the Strengths and Difficulties Questionnaire (SDQ). The Revised Childrens Quality of Life Questionnaire (KINDL-R) was used to measure quality of life. The comparison group (n = 6,813) was a representative sample from the German KiGGS study. Results The proportion of youths with mental health problems (defined as abnormal SDQ total difficulties score) was, based on self-reports, 4.4% in the patient group and 2.9% in the general population (adjusted OR = 1.61, p = 0.044); and based on proxy reports, 7.9% in the patient group and 7.2% in the general population (OR = 1.05, p = 0.788). Youths with type 1 diabetes and self-reported mental health problems scored worse in the KINDL-R subscales of physical well-being (adjusted average difference β = −16.74, p<0.001) and family (β = −11.09, p = 0.017), and in the KINDL-R total score (β = −8.09, p<0.001), than peers with self-reported mental health problems. The quality of life of diabetic adolescents and proxy-reported mental health problems did not differ from peers with proxy-reported mental health problems adjusted for confounders. Conclusions Compared with the general population with mental health problems, the quality of life of adolescents with type 1 diabetes who report mental health problems is more severely impaired. This observation calls for early prevention and intervention as part of pediatric diabetes long-term care.

Studies analysing the need for health-related information in Germany - a systematic review

BackgroundExploring health-related information needs is necessary to better tailor information. However, there is a lack of systematic knowledge on how and in which groups information needs has been assessed, and which information needs have been identified. We aimed to assess the methodology of studies used to assess information needs, as well as the topics and extent of health-related information needs and associated factors in Germany.MethodsA systematic search was performed in Medline, Embase, Psycinfo, and all databases of the Cochrane Library. All studies investigating health-related information needs in patients, relatives, and the general population in Germany that were published between 2000 and 2012 in German or English were included. Descriptive content analysis was based on predefined categories.ResultsWe identified 19 studies. Most studies addressed cancer or rheumatic disease. Methods used were highly heterogeneous. Apart from common topics such as treatment, diagnosis, prevention and health promotion, etiology and prognosis, high interest ratings were also found in more specific topics such as complementary and alternative medicine or nutrition. Information needs were notable in all surveyed patient groups, relatives, and samples of the general population. Younger age, shorter duration of illness, poorer health status and higher anxiety and depression scores appeared to be associated with higher information needs.ConclusionKnowledge about information needs is still scarce. Assuming the importance of comprehensive information to enable people to participate in health-related decisions, further systematic research is required.
