ABSTRACT
There are known geographical differences in growth hormone deficiency (GHD) patient populations and treatment practices. Here, we present a comparison of safety and effectiveness data from patients treated with recombinant human growth hormone (rhGH) in the USA versus other countries. PAtients TReated with Omnitrope® (PATRO) Children is an international, non-interventional study with Omnitrope® (somatropin, Sandoz Inc.). All visits and assessments are carried out according to routine clinical practice, and doses of Omnitrope® are given according to country-specific prescribing information. By September 2018, 294 patients had been enrolled in the USA (53% rhGH-naïve) and 6206 patients had been enrolled across 13 other countries (international group; 86% rhGH-naïve). The most common indication in both groups was GHD. Overall, 194 US patients (66%) and 2977 international patients (48%) experienced adverse events (AEs; 886 and 11,716 events, respectively), most of which were of mild or moderate intensity. The AEs were suspected to be treatment-related in five US patients (1.7%) and 452 international patients (7.3%). All reported neoplasms were benign, non-serious, and considered unrelated to rhGH therapy. No cases of diabetes mellitus or hyperglycemia were reported. In rhGH-naïve GHD patients, after 3 years of rhGH therapy, the improvement in mean height SD score from baseline was + 1.25 and + 1.35 in US and international patients, respectively. CONCLUSION: Omnitrope® treatment appears to be well tolerated and effective in US patients and those from other countries. Across the pediatric indications included, there was no evidence of an increased risk of developing uncommon or unexpected AEs with rhGH. TRIAL REGISTRATION: NA. WHAT IS KNOWN: ⢠Continued monitoring of patients treated with recombinant human growth hormone (rhGH) is important, particularly in terms of diabetogenic potential and the risk of malignancies. ⢠The PAtients TReated with Omnitrope® (PATRO) Children study is a long-term, post-marketing surveillance program for the rhGH Omnitrope®. WHAT IS NEW: ⢠Omnitrope® is well tolerated and effective in US patients, and those from other countries. ⢠Across all indications included, there were no unexpected adverse events and there was no evidence of an increased risk of developing malignancies or diabetes.

Neonatal screening for congenital primary hypothyroidism (CH) may not distinguish between transient (TCH) and permanent dysfunction (PCH), causing potential overtreatment and concerns in affected families. To specify the indication for interruption of therapy, we analysed the German registry "HypoDok" for infants with CH, which oversees 1625 patients from 49 participating centres in Germany and Austria from 1997 until today. A total of 357 patients with a thyroid gland in loco typico were identified and retrospectively grouped according to cessation (TCH, n = 24) or continuation (PCH, n = 333) of L-thyroxine (L-T4) treatment at 2 years of age. The receiver operating characteristic (ROC) analysis was performed to identify cutoffs predicting TCH by screening TSH concentrations and L-T4 dosages. Gestational ages, birth weights and prevalence of associated malformations were comparable in both groups. The cutoff screening TSH concentration was 73 mU/L. The cutoff daily L-T4 dosage at 1 year was 3.1 µg/kg (90% sensitivity, 63% specificity; 36 µg/day) and at 2 years of age 2.95 µg/kg (91% sensitivity, 59% specificity; 40 µg/day). At 2 years of age, specificity (71%) increased when both of these parameters were considered together.Conclusion: The decision to continue or cease L-T4 treatment at 2 years of age in CH patients diagnosed in neonatal screening may be based on their screening TSH concentrations and individual L-T4 dosages at 1 and 2 years of age. Thus, TCH and PCH may be distinguished; overtreatment avoided; and affected families reassured. What is Known: ⢠The course of congenital primary hypothyroidism may be transient, causing potential overtreatment. ⢠The dose of l-thyroxine at 1 or 2 years of age may predict a transient course of primary congenital hypothyroidism. What is New: ⢠TSH screening concentration and l-thyroxine dosages at 1 and 2 years of age represent reliable predictors for transient congenital primary hypothyroidism with higher sensitivity and specificity when considered together in order to select eligible patients who qualify for treatment withdrawal.

BACKGROUND/OBJECTIVE: Microvascular alterations play a key role in the development of diabetes complications. Retinal vessel analysis is a unique method to examine microvascular changes in brain-derived vessels. METHODS: Sixty-seven pediatric and adolescent type 1 diabetes patients and 58 healthy control persons (mean age 12.4 ± 2.9 years) underwent non-mydriatic retinal photography of both eyes. Central retinal arteriolar and central retinal venular (CRVE) diameter equivalents as well as the arteriolar-to-venular ratio were calculated using a semiautomated software. All anthropometric and laboratory parameters were measured according to standardized procedures for children. RESULTS: Retinal vessel diameter did not differ between type 1 diabetic children and healthy controls. However, there was an independent association of higher hemoglobin A1c (HbA1c) levels with arteriolar narrowing. Arteriolar narrowing of 5.4 µm was observed with each percent increase in HbA1c. Longer duration of diabetes was associated with wider retinal arterioles. CRVE was not associated with diabetes duration or HbA1c. CONCLUSIONS: Microvascular arteriolar alterations are already present in childhood and may indicate subclinical atherosclerosis and increased risk of diabetes complications later in life. Future research will have to investigate the potential use of retinal vessel diameters for treatment monitoring and guidance of therapy in children.

BACKGROUND: Recommendations on preventive lipid screening among children and adolescents remain controversial. The aim of the study was to assess age and puberty-related changes in serum lipids, including total cholesterol (TC), and high-density (HDL-C) and non-high-density lipoprotein cholesterol (Non-HDL-C). METHODS: Using cross-sectional data from the National Health Interview and Examination Survey for Children and Adolescents in Germany (KiGGS 2003-2006; N = 13,676; 1-17 years), changes in distributions of serum lipids were visualized according to sex, age and maturation. Youth aged 10-17 years were classified as prepubescent, early/mid-puberty, and mature/advanced puberty. Multiple linear regressions were used to quantify the impact of pubertal stage on serum lipid levels, adjusted for potential confounding factors. RESULTS: Among children 1-9 years mean serum lipid measures increased with age, with higher mean TC and Non-HDL-C among girls than boys. Among children 10-17 years, advanced pubertal stage was independently related to lower lipid measures. Adjusted mean TC, HDL-C and Non-HDL-C was 19.4, 5.9 and 13.6 mg/dL lower among mature/advanced puberty compared to prepubescent boys and 11.0, 4.0 and 7.0 mg/dL lower in mature/advanced puberty compared to prepubescent girls. CONCLUSIONS: Lipid concentrations undergo considerable and sex-specific changes during physical growth and sexual maturation and significantly differ between pubertal stages. Screening recommendations need to consider the fluctuations of serum lipids during growth and sexual maturation.

Background A legitimate indication for growth hormone (GH) therapy in children born too light or short at birth [small-for-gestational age (SGA)] exists in Germany and the European Union only if special criteria are met. Methods We conducted a longitudinal, multi-centered study on full-term appropriate-for-gestational age (AGA, n=1496) and pre-term born SGA (n=173) and full-term SGA children (n=891) in Germany from 2006 to 2010. We analyzed height, weight, body mass index (BMI) and head circumference. Results Pre-term or full-term born SGA children were shorter, lighter and had a lower BMI from birth until 3 years of age than full-term AGA children. The growth velocity of the analyzed anthropometric measurements was significantly higher in pre-term and full-term SGA children exclusively in the first 2 years of life than in AGA children. The criteria for GH treatment were fulfilled by 12.1% of pre-term SGA children compared to only 1.3% of full-term SGA children. Conclusion For children that do not catch up growth within the first 2 years of life, an earlier start of GH treatment should be considered, because a catch-up growth later than 2 years of life does not exist. Pre-term SGA-born children more frequently fulfill the criteria for GH treatment than full-term SGA children.

A significant influence of maternal body height and weight on neonatal birth outcome has been confirmed before, whereas the influence of paternal traits is rather unknown. In order to analyze the correlation between parental body measurements and the birth weight of newborns, data of 1312 eutrophic term newborns and their parents were collected based on a multicenter study in 10 participating German maternity clinics. The collected data included the birth weight of the infants and the body height and weight of their parents. The results show a significant correlation between infant birth weight and maternal body height. Even with a constant body height and body weight of fathers in a range between 176-184 cm and 76-84 kg, taller mothers gave birth to children with a higher birth weight than shorter mothers. Furthermore, higher maternal body weight is also correlated with increased birth weights, although this correlation is attenuated in higher maternal weight groups. Data regarding body weight and body height of fathers showed similar results with regard to birth weight of the newborns. At a constant maternal body height (164-172 cm) and weight (56-64 kg), the body weight of newborns significantly correlates with the body height of fathers but not with their body weight. The multivariable regression analysis resulted in the following ranking of influence factors on the birth weight of newborns: 1) body height of mother, 2) body weight of mother, 3) body height of father. The results gave support to the assumption of a certain genetic influence of parental body stature on their neonates but argue for an even stronger impact of maternal environmental conditions on the developmental status of neonates.

OBJECTIVE: To investigate differences in cardiovascular risk factors and metabolic control in girls with type 1 diabetes with or without use of oral contraceptives (OC) from the multicenter "diabetes prospective follow-up" (DPV) registry. METHODS: Twenty-four thousand eleven adolescent girls (13 to < 18 years of age) from Germany, Austria or Luxembourg with type 1 diabetes from the DPV registry were included in this cross-sectional study. Multivariable regression models were applied to compare clinical characteristics (hemoglobin A1c [HbA1C ], blood pressure, serum lipids, body mass index) and lifestyle factors (smoking, physical inactivity, alcohol consumption) between girls with or without OC use. Confounders: age, diabetes duration and migration background. STATISTICAL ANALYSIS: SAS 9.4. RESULTS: In girls with type 1 diabetes and OC use, clinical characteristics and lifestyle factors were less favorable compared to non-users. Differences were most pronounced for the prevalence of dyslipidemia (OC-users: 40.0% vs non-users: 29.4; P < .0001) and the number of smokers (OC-users: 25.9% vs non-users: 12.5%; P < .0001). OC use, sociodemographic characteristics and lifestyle factors explained between 1 and 7% of the population variance in serum lipids and blood pressure. The use of OC explained a small additional proportion in all variables considered (<1%). CONCLUSIONS: OC use in adolescent girls with type 1 diabetes was associated with a poorer cardiovascular risk profile. Biological risk factors were partly explained by a clustering of sociodemographic and lifestyle factors with a small additional contribution of OC use. Prescription of OC should therefore be combined with a screening for cardiovascular risk factors and targeted education.

BACKGROUND: Maple syrup urine disease (MSUD) is an autosomal recessive disorder of branched-chain amino acid metabolism. Patients with MSUD are at risk of life-threatening metabolic decompensations with ketoacidosis and encephalopathy. These episodes are often triggered by physiological stress. Only few cases of pregnancies in MSUD mothers have been reported so far. CASE PRESENTATION: We present the favorable outcome of a pregnancy in a woman with classical MSUD. She presented in the metabolic outpatient clinic in week 7 of gestation. Branched-chain amino acid concentrations were measured at least weekly to adjust dietary leucine intake. Despite excellent compliance, leucine concentrations frequently exceeded the target value of < 300 µmol/L during the first trimester. From the second trimester until delivery, protein and leucine intake increased continuously to about threefold compared to pre-pregnancy values. To maximize patient safety during delivery and the postpartum period, a detailed plan including peripartal infusion therapy, dietary recommendations and monitoring parameters was developed. Primary Caesarean section was performed in week 38 of gestation, and the patient gave birth to a healthy girl. Lactation was successfully implemented. Leucine levels were maintained within the target range throughout the complete postpartum period. In addition to our case, we give an overview about all cases of pregnancies in MSUD mothers published so far. CONCLUSIONS: Management of pregnancy, delivery, postpartum period and lactation may be challenging in patients with MSUD. Careful monitoring and interdisciplinary collaboration is essential to minimize the risk of metabolic crisis, especially after delivery.

2-methylacetoacetyl-coenzyme A thiolase (MAT) deficiency, also known as beta-ketothiolase deficiency, is an inborn error of ketone body utilization and isoleucine catabolism. It is caused by mutations in the ACAT1 gene and may present with metabolic ketoacidosis. In order to obtain a more comprehensive view on this disease, we have collected clinical and biochemical data as well as information on ACAT1 mutations of 32 patients from 12 metabolic centers in five countries. Patients were between 23months and 27years old, more than half of them were offspring of a consanguineous union. 63% of the study participants presented with a metabolic decompensation while most others were identified via newborn screening or family studies. In symptomatic patients, age at manifestation ranged between 5months and 6.8years. Only 7% developed a major mental disability while the vast majority was cognitively normal. More than one third of the identified mutations in ACAT1 are intronic mutations which are expected to disturb splicing. We identified several novel mutations but, in agreement with previous reports, no clear genotype-phenotype correlation could be found. Our study underlines that the prognosis in MAT deficiency is good and MAT deficient individuals may remain asymptomatic, if diagnosed early and preventive measures are applied.

3-Hydroxy-3-methylglutaryl-coenzyme A lyase deficiency (HMGCLD) is a rare inborn error of ketone body synthesis and leucine degradation, caused by mutations in the HMGCL gene. In order to obtain a comprehensive view on this disease, we have collected clinical and biochemical data as well as information on HMGCL mutations of 37 patients (35 families) from metabolic centers in Belgium, Germany, The Netherlands, Switzerland, and Turkey. All patients were symptomatic at some stage with 94% presenting with an acute metabolic decompensation. In 50% of the patients, the disorder manifested neonatally, mostly within the first days of life. Only 8% of patients presented after one year of age. Six patients died prior to data collection. Long-term neurological complications were common. Half of the patients had a normal cognitive development while the remainder showed psychomotor deficits. We identified seven novel HMGCL mutations. In agreement with previous reports, no clear genotype-phenotype correlation could be found. This is the largest cohort of HMGCLD patients reported so far, demonstrating that HMGCLD is a potentially life-threatening disease with variable clinical outcome. Our findings suggest that the clinical course of HMGCLD cannot be predicted accurately from HMGCL genotype. The overall outcome in HMGCLD appears limited, thus rendering early diagnosis and strict avoidance of metabolic crises important.

OBJECTIVE: To examine the current extent of the obesity problem in 2 large pediatric clinical registries in the US and Europe and to examine the hypotheses that increased body mass index (BMI) z-scores (BMIz) are associated with greater hemoglobin A1c (HbA1c) and increased frequency of severe hypoglycemia in youth with type 1 diabetes (T1D). STUDY DESIGN: International (World Health Organization) and national (Centers for Disease Control and Prevention/German Health Interview and Examination Survey for Children and Adolescents) BMI references were used to calculate BMIz in participants (age 2-<18 years and ≥ 1 year duration of T1D) enrolled in the T1D Exchange (n = 11,435) and the Diabetes Prospective Follow-up (n = 21,501). Associations between BMIz and HbA1c and severe hypoglycemia were assessed. RESULTS: Participants in both registries had median BMI values that were greater than international and their respective national reference values. BMIz was significantly greater in the T1D Exchange vs the Diabetes Prospective Follow-up (P < .001). After stratification by age-group, no differences in BMI between registries existed for children 2-5 years, but differences were confirmed for 6- to 9-, 10- to 13-, and 14- to 17-year age groups (all P < .001). Greater BMIz were significantly related to greater HbA1c levels and more frequent occurrence of severe hypoglycemia across the registries, although these associations may not be clinically relevant. CONCLUSIONS: Excessive weight is a common problem in children with T1D in Germany and Austria and, especially, in the US. Our data suggest that obesity contributes to the challenges in achieving optimal glycemic control in children and adolescents with T1D.

Alpha-aminoadipic and alpha-ketoadipic aciduria is an autosomal recessive inborn error of lysine, hydroxylysine, and tryptophan degradation. To date, DHTKD1 mutations have been reported in two alpha-aminoadipic and alpha-ketoadipic aciduria patients. We have now sequenced DHTKD1 in nine patients diagnosed with alpha-aminoadipic and alpha-ketoadipic aciduria as well as one patient with isolated alpha-aminoadipic aciduria, and identified causal mutations in eight. We report nine novel mutations, including three missense mutations, two nonsense mutations, two splice donor mutations, one duplication, and one deletion and insertion. Two missense mutations, one of which was reported before, were observed in the majority of cases. The clinical presentation of this group of patients was inhomogeneous. Our results confirm that alpha-aminoadipic and alpha-ketoadipic aciduria is caused by mutations in DHTKD1, and further establish that DHTKD1 encodes the E1 subunit of the alpha-ketoadipic acid dehydrogenase complex.

BACKGROUND: Impaired blood pressure regulation contributes to the development of diabetic complications. The influence of systolic (SBP) vs.diastolic blood pressure (DBP) is still controversial. Peripheral pulse pressure(PP), the difference between SBP and DBP, is an indicator for arterial stiffness. Only little data are available for PP in children. Therefore, we studied PP regulation in type 1 diabetic children and adolescents.Methods: Blood pressure values of 46 737 patients with T1DM younger than 20 years are documented in the DPV database and were compared with the control populations of the '4th report on high blood pressure (4th report)' and the German KIGGS study. RESULTS: PP is increased in 63% (4th report) or 67% (KIGGS) of the patients,respectively. The rate of increased PP remains stable between 59 and 68%,irrespective of sex, age, and the control population. Absolute PP is elevated independently of the control population (PP T1DM 49.13±11.1 vs. 4th report 45.38 ± 3 vs. KIGGS 44.58 ± 4.6 mmHg; all p<0.0001, Wilcoxon test)and increases with age in both sexes. Age, male sex, diabetes duration, insulin dose, and body mass index (BMI) are independent factors contributing to elevated absolute PP levels and to the prevalence of wide PP. HbA1c is negligible negatively related to increased PP levels (multiple linear regression). CONCLUSIONS: In T1DM increased PP is a marker for accelerated arterial stiffness and aging and should be considered as an additional risk factor in the treatment of diabetic children. Elevated PP in children with T1DM may contribute to the high risk for early development of atherosclerosis.

INTRODUCTION: Growth hormone (GH) treatment in children with growth hormone deficiency (GHD), short children born small for gestational age (SGA), and Turner syndrome (TS) is well established. However, a variety of parameters are still under discussion to achieve optimal growth results and efficiency of GH use in real-world treatment. METHODS: German GH-treatment naïve patients of the PATRO Children database were grouped according to their start of treatment into groups of 3 years from 2007 to 2018. Time trends in age, gender, GH dose, height standard deviation score (SDS), first-year growth response, and Index of Responsiveness (IoR) were investigated in children with GHD, short children born SGA, and TS starting GH treatment in the German patient population of the PATRO Children database from 2007 to 2018 to determine specific parameters for GH treatment optimization. RESULTS: All patient groups started GH treatment at a relatively high chronological age (2007-2009: GHD 8.33 ± 3.19, SGA 7.32 ± 2.52, TS 8.65 ± 4.39) with a slight but not significant trend towards younger therapy start up to 2016-2018 (GHD 8.04 ± 3.36, SGA 6.67 ± 2.65, TS 7.85 ± 3.38). In the GHD and SGA groups, female patients were underrepresented compared to male patients (GHD 32.3%, SGA 43.6%) with no significant change over the 4 time periods. Patients with GHD started GH treatment at a low dose (0.026 mg/kg/day). In SGA and TS patients, GH therapy was started below the registered dose recommendation (30.0 µg/kg/day and 33.7 µg/kg/day, respectively). In the first year of treatment, the mean GH dose was increased moderately (GHD: 30.7, SGA: 35.7, TS: 40.8 µg/kg/day). There was no significant change of GH dosing over time from 2007 to 2018. The IoR was comparable between time-groups for all 3 diagnoses. DISCUSSION: This study shows potential for improvement of GH treatment results in GHD, SGA, and TS patients in terms of early dose adjustment and younger age at the start of treatment. This is in accordance with important parameters used in prediction models.
ABSTRACT
Purpose: Omnitrope® (somatropin) was approved as a biosimilar recombinant human growth hormone (rhGH) in 2006. Here, we report final data from the PAtients TReated with Omnitrope® (PATRO) Children study, a post-marketing surveillance study designed to monitor the long-term safety and effectiveness of this treatment in pediatric patients. Methods: The study population included all pediatric patients treated with Omnitrope® (biosimilar rhGH), administered via daily injection, in routine clinical practice. The primary objective was to assess long-term safety, with effectiveness assessed as a secondary objective. Results: In total, 7359 patients were enrolled and treated in the PATRO Children study; 86.0% were treatment-naïve at baseline. Growth hormone deficiency was the most frequent indication (57.9%), followed by patients born small for gestational age (SGA; 26.6%). The mean (SD) duration of exposure to biosimilar rhGH was 3.66 years (2.39). A total of 16,628 adverse events (AEs) were reported in 3981 (54.1%) patients, most of which were mild/moderate. AEs suspected to be treatment related occurred in 8.3% of patients, most frequently headache (1.6%), injection-site pain (1.1%), or injection-site hematoma (1.1%). The incidence rate (IR) of type 2 diabetes mellitus was 0.11 per 1000 person-years (PY) across all patients, and 0.13 per 1000 PY in patients born SGA. The IR of newly diagnosed primary malignancies was 0.22 per 1000 PY across all patients. In the 6589 patients included in the effectiveness population, a sustained catch-up growth was observed across all indications. After 5 years of treatment, height SDS increased from baseline by a median (range) of +1.79 (-3.7 to 6.2) in treatment-naïve patients and +0.73 (-1.4 to 3.7) in pretreated patients. Conclusion: This final analysis of the PATRO Children study indicates that biosimilar rhGH is well tolerated and effective in real-world clinical practice. These data are consistent with the well-characterized safety profile of rhGH treatment in pediatric patients.

BACKGROUND: The diverse stages of the COVID-19 pandemic led to several social circumstances that influenced daily life and health behavior. PURPOSE: To evaluate changes in cardiovascular risk factors and physical activity among children and young adults with type 1 diabetes (T1D) during the COVID-19 pandemic in Germany compared to previous years. METHODS: A total of 32 785 individuals aged 6-21 years at baseline with T1D from the German diabetes patient follow-up (DPV) registry contributed data on 101 484 person-years between 2016 and 2021. The first treatment year of each individual within this period was considered as baseline. Based on trends from 2016 to 2019, we estimated differences in body mass index-SD score (BMI-SDS), blood pressure (BP-SDS), and lipid levels (non-high-density lipoprotein [non-HDL]) between observed and predicted estimates for the years 2020 and 2021 using linear regression analysis standardized for age, diabetes duration, sex, and migratory background. The proportion doing organized sports and smoking cigarettes was analyzed using multivariable logistic regression models. RESULTS: BMI-SDS increased constantly from 2016 to 2021 without a significant increase above expected values for 2020/2021. Systolic BP-SDS (difference observed vs. expected with 95% confidence interval, 2020: 0.10 [0.07-0.14], 2021: 0.17 [0.14-0.20]) and non-HDL (2020: 2.7 [1.3-4.1] mg/dl, 2021: 4.1 [2.7-5.5] mg/dl) were significantly increased (all p < .001) in both pandemic years. The proportion of subjects participating in organized sports was reduced from over 70% in prepandemic years to 35%-65% in diverse stages/waves of the COVID-19 pandemic. The percentage smoking cigarettes did not change. CONCLUSIONS: We describe an increase in BP and atherogenic lipid levels coinciding with a reduction in physical activity but no acceleration of the prepandemic increases in BMI-SDS among young people with T1D during the COVID-19 pandemic.

BACKGROUND: The daily demands of type 1 diabetes management may jeopardize adolescents' mental health. We aimed to assess anxiety and depression symptoms by broad-scale, tablet-based outpatient screening in adolescents with type 1 diabetes in Germany. METHODS: Adolescent patients with type 1 diabetes mellitus (n = 2,394; mean age 15.4 y [SD 2.0]; 50.7% male) were screened for anxiety (GAD-7) and depression symptoms (PHQ-9) by self-report questionnaires and linked to clinical data from the DPV patient registry. Logistic regression was used to estimate the contribution of clinical parameters to positive screening results. RESULTS: Altogether, 30.2% showed a positive screening (score ≥ 7 in either test), and 11.3% reported suicidal ideations or self-harm. Patients with anxiety and depression symptoms were older (15.7 y [CI 15.5-15.8] vs. 15.3 y [CI 15.2-15.4]; p < 0.0001), had higher HbA1c levels (7.9% [CI 7.8-8.0] (63 mmol/mol) vs. 7.5% [CI 7.4-7.5] (58 mmol/mol); p < 0.0001), and had higher hospitalization rates. Females (adjusted odds ratio (aOR) 2.66 [CI 2.21-3.19]; p < 0.0001), patients > 15 years (aOR 1.40 [1.16-1.68]; p < 0.001), who were overweight (aOR 1.40 [CI 1.14-1.71]; p = 0.001), with HbA1c > 9% (> 75 mmol/mol; aOR 2.58 [1.83-3.64]; each p < 0.0001), with a migration background (aOR 1.46 [CI 1.17-1.81]; p < 0.001), or smoking (aOR 2.72 [CI 1.41-5.23]; p = 0.003) had a higher risk. Regular exercise was a significant protective factor (aOR 0.65 [CI 0.51-0.82]; p < 0.001). Advanced diabetes technologies did not influence screening outcomes. CONCLUSIONS: Electronic mental health screening was implemented in 42 centers in parallel, and outcomes showed an association with clinical parameters from sociodemographic, lifestyle, and diabetes-related data. It should be integrated into holistic patient counseling, enabling early recognition of mild mental health symptoms for preventive measures. Females were disproportionally adversely affected. The use of advanced diabetes technologies did not yet reduce the odds of anxiety and depression symptoms in this cross-sectional assessment.
