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.

Is disordered eating behavior more prevalent in adolescents with early-onset type 1 diabetes than in their representative peers?

OBJECTIVE Despite modern therapeutic regimens, youths with Type 1 diabetes may be at increased risk of mental and behavioral disorders. In this study, the prevalence of disordered eating behavior (DEB) in intensely treated children and adolescents with early-onset Type 1 diabetes and peers from the general population was compared. METHOD Data from 629 patients from a population-based, nationwide survey (54.1% male, mean age 15.3 years) with early-onset Type 1 diabetes of at least 10 years duration were compared with data from 6,813 participants of the German KiGGS study (51.3% male, mean age 14.6 years). The generic SCOFF questionnaire was used as screening instrument to identify participants with symptoms of DEB. Both groups were compared with multivariable regression analysis adjusting for sociodemographic covariates. RESULTS 31.2% of the female and 11.7% of the male diabetic patients and 28.9% of the females and 15.2% of the males in the comparison group were SCOFF-positive (SCOFF score ≥2; p > .05). The odds for symptoms of eating disorders were 3.7% higher in female and 4.3% lower in male patients with diabetes than in the comparison group, but the differences were not significant. 20.5% of the female and 18.5% of the male diabetic patients reported insulin restriction at least three times per week. DISCUSSION Children and adolescents with early-onset Type 1 diabetes of long duration do not seem to be more frequently SCOFF-positive than peers. However, as insulin restriction is practiced in a substantial portion of patients, attention for insulin restriction in diabetes care is essential.

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.

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.

Symptoms of Eating Disorders and Depression in Emerging Adults with Early-Onset, Long-Duration Type 1 Diabetes and Their Association with Metabolic Control.

Background This study analyzed the prevalence of and association between symptoms of eating disorders and depression in female and male emerging adults with early-onset, long-duration type 1 diabetes and investigated how these symptoms are associated with metabolic control. Methods In a nationwide population-based survey, 211 type 1 diabetes patients aged 18-21 years completed standardized questionnaires, including the SCOFF questionnaire for eating disorder symptoms and the Patient Health Questionnaire (PHQ-9) for symptoms of depression and severity of depressive symptoms (PHQ-9 score). Multiple linear and logistic regression models were used to analyze the association between eating disorder and depressive symptoms and their associations with HbA1c. Results A total of 30.2% of the women and 9.5% of the men were screening positive for eating disorders. The mean PHQ-9 score (standard deviation) was 5.3 (4.4) among women and 3.9 (3.6) among men. Screening positive for an eating disorder was associated with more severe depressive symptoms among women (βwomen 3.8, p<0.001). However, neither eating disorder symptoms nor severity of depressive symptoms were associated with HbA1c among women, while HbA1c increased with the severity of depressive symptoms among men (βmen 0.14, p=0.006). Conclusions Because of the high prevalence of eating disorder and depressive symptoms, their interrelationship, and their associations with metabolic control, particularly among men, regular mental health screening is recommended for young adults with type 1 diabetes.

Impact of quality of life (QoL) on glycemic control (HbA1c) among adolescents and emerging adults with long‐duration type 1 diabetes: A prospective cohort‐study

Risk of Microvascular Complications and Macrovascular Risk Factors in Early-Onset Type 1 Diabetes after at Least 10 Years Duration: An Analysis of Three Population-Based Cross-Sectional Surveys in Germany between 2009 and 2016

Aims To estimate the risk of microvascular complications and macrovascular risk factors among persons with early-onset (diagnosed at ages 0 to <5 years) and long-duration type 1 diabetes and determine temporal trends and associations with potential predictors. Methods We conducted three population-based cross-sectional surveys in Germany (N = 1789) to obtain information on exposures and five outcomes (retinopathy, nephropathy, dyslipidemia, hypertension, and a composite endpoint combining all four outcomes). For each outcome, log-binomial spline regression was applied to estimate the risk and dose-response relationship with diabetes duration and exposures. Results The risk for microvascular complications increased after 14 years since diabetes diagnosis whereas dyslipidemia and hypertension were already prevalent at 10 years. The 15-year risk (95% confidence interval) of the composite endpoint for female and male patients was 22.9% (18.8%–27.9%) and 19.2% (15.5%–23.8%), respectively. Temporal trends suggested a decreasing risk between 2009 and 2016. Glycemic control, lifestyle-related factors, and SES, but not health care-related factors, were associated with the risk of the composite endpoint. Conclusions In early-onset type 1 diabetes, there exists a considerable risk of complications and comorbidities already in young ages. Future research should focus on prevention of diabetic complications in young patients and clarification of pathways of the associations found.
