Association and Familial Coaggregation of Childhood-Onset Type 1 Diabetes With Depression, Anxiety, and Stress-Related Disorders: A Population-Based Cohort Study

Long-term physical health conditions and youth anxiety and depression: Is there a causal link?

BACKGROUND

The prevalence of youth anxiety and depression has increased globally, with limited causal explanations. Long-term physical health conditions (LTCs) affect 20-40% of youth, with rates also rising. LTCs are associated with higher rates of youth depression and anxiety; however, it is uncertain whether observed associations are causal or explained by unmeasured confounding or reverse causation.

METHODS

Using data from the Norwegian Mother, Father, and Child Cohort Study (MoBa) and Norwegian National Patient Registry, we investigated phenotypic associations between childhood LTCs, and depression and anxiety diagnoses in youth (<19 years), defined using ICD-10 diagnoses and self-rated measures. We then conducted two-sample Mendelian Randomization (MR) analyses using SNPs associated with childhood LTCs from existing genome-wide association studies (GWAS) as instrumental variables. Outcomes were: (i) diagnoses of major depressive disorder (MDD) and anxiety disorders or elevated symptoms in MoBa, and (ii) youth-onset MDD using summary statistics from a GWAS in iPSYCH2015 cohort.

RESULTS

Having any childhood LTC phenotype was associated with elevated youth MDD (OR = 1.48 [95% CIs 1.19, 1.85], p = 4.2×10-4) and anxiety disorder risk (OR = 1.44 [1.20, 1.73], p = 7.9×10-5). Observational and MR analyses in MoBa were consistent with a causal relationship between migraine and depression (IVW OR = 1.38 [1.19, 1.60], pFDR = 1.8x10-4). MR analyses using iPSYCH2015 did not support a causal link between LTC genetic liabilities and youth-onset depression or in the reverse direction.

CONCLUSIONS

Childhood LTCs are associated with depression and anxiety in youth, however, little evidence of causation between LTCs genetic liability and youth depression/anxiety was identified from MR analyses, except for migraine.

Major cardiovascular events and death in parents of children with type 1 diabetes: a register-based matched cohort study in Sweden

AIMS/HYPOTHESIS

Parenting a child with type 1 diabetes has been associated with stress-related symptoms. This study aimed to elucidate the potential impact on parental risk of major cardiovascular events (MCE) and death.

METHODS

In this register-based study, we included the parents of 18,871 children, born 1987-2020 and diagnosed with type 1 diabetes in Sweden at <18 years. The median parental age at the child's diagnosis was 39.0 and 41.0 years for mothers and fathers, respectively. The cohort also encompassed 714,970 population-based matched parental control participants and 12,497 parental siblings. Cox proportional hazard regression models were employed to investigate the associations between having a child with type 1 diabetes and incident MCE and all-cause death, and, as secondary outcomes, acute coronary syndrome and ischaemic heart disease (IHD). We adjusted for potential confounders including parental type 1 diabetes and country of birth.

RESULTS

During follow-up (median 12 years, range 0-35), we detected no associations between parenting a child with type 1 diabetes and MCE in mothers (adjusted HR [aHR] 1.02; 95% CI 0.90, 1.15) or in fathers (aHR 1.01; 95% CI 0.94, 1.08). We noted an increased hazard of IHD in exposed mothers (aHR 1.21; 95% CI 1.05, 1.41) with no corresponding signal in fathers (aHR 0.97; 95% CI 0.89, 1.05). Parental sibling analysis did not confirm the association in exposed mothers (aHR 1.01; 95% CI 0.73, 1.41). We further observed a slightly increased hazard of all-cause death in exposed fathers (aHR 1.09; 95% CI 1.01, 1.18), with a similar but non-significant estimate noted in exposed mothers (aHR 1.07; 95% CI 0.96, 1.20). The estimates from the sibling analyses of all-cause death in fathers and mothers were 1.12 (95% CI 0.90, 1.38) and 0.73 (95% CI 0.55, 0.96), respectively.

CONCLUSIONS/INTERPRETATION

Having a child diagnosed with type 1 diabetes in Sweden was not associated with MCE, but possibly with all-cause mortality. Further studies are needed to disentangle potential underlying mechanisms, and to investigate parental health outcomes across the full lifespan.

Childhood-onset type 1 diabetes and subsequent adult psychiatric disorders: a nationwide cohort and genome-wide Mendelian randomization study

Childhood-onset type 1 diabetes (T1D) is associated with substantial psychiatric morbidity in later life, but it remains unknown whether these associations are due to common underlying biological mechanisms or the impacts of living with the condition and its treatment. Here, using Czech national register data, we identified children with T1D aged ≤14 years between 1994 and 2007 and estimated the risk of psychiatric disorders up to 24 years later. We found that children diagnosed with T1D had an elevated risk of developing substance use, mood, anxiety and personality disorders, and behavioral syndromes. Conversely, we found that children with T1D had a lower risk of developing psychotic disorders. In Mendelian randomization analysis, we found an association with schizophrenia, which, however, did not persist following multiple testing adjustment. The combined observational and Mendelian randomization evidence suggests that T1D diagnosis in childhood predisposes to far-reaching, extensive psychiatric morbidity, which is unlikely to be explicable by common underlying biological mechanisms. The findings of this study highlight that monitoring and addressing the mental health needs of children with T1D is imperative, whereas glucose dysregulation and/or inflammation implicated in schizophrenia pathogenesis warrants future research.

Type 1 diabetes-related distress: Current implications in care

Type 1 diabetes (T1D) is a complex chronic disease associated with major health and economic consequences, also involving important issues in the psychosocial sphere. In this regard, T1D-related distress, defined as the emotional burden of living with T1D, has emerged as a specific entity related to the disease. Diabetes distress (DD) is an overlooked but prevalent condition in people living with T1D, and has significant implications in both glycemic control and mental health in this population. Although overlapping symptoms may be found between DD and mental health disorders, specific approaches should be performed for the diagnosis of this problem. In recent years, different DD-targeted interventions have been postulated, including behavioral and psychosocial strategies. Moreover, new technologies in this field may be helpful to address DD in people living with T1D. In this article, we summarize the current knowledge on T1D-related distress, and we also discuss the current approaches and future perspectives in its management.

The association between depressive symptoms and executive function in type 1 diabetes population: A scoping review

PURPOSE

The purpose of this study was to explore the existing literature on the relationship between depressive symptoms and executive function in patients with type 1 diabetes (T1DM) across the lifespan.

METHODS

The scoping review followed the PRISMA protocol by using three databases: PubMed, CINAHL, and PsycINFO on May 14, 2023. Primary research that included reported executive function and the association with depressive symptoms was included in the review.

RESULTS

Of 1470 de-duplicated publications identified, nine articles were included in the review. Five studies evaluated the T1DM population, while four studies evaluated T1DM and type 2 diabetes (T2DM) as an aggregate result. Three studies indicated an association between depressive symptoms and executive function in adults with T1DM, and four studies indicated an association between depressive symptoms and executive function in adults with either T1DM or T2DM. In general, participants who reported depressive symptoms also exhibited poor executive function. However, two studies did not find an association between depressive symptoms and executive function.

CONCLUSION

In summary, the seven studies in this review suggest that individuals with T1DM who report depressive symptoms are at a higher risk of poor executive function; a clear association between depressive symptoms and executive function in individuals with T1DM remains inconclusive. There is a need to explore this relationship in the future.

Psychosocial Burden During the COVID-19 Pandemic in Adolescents With Type 1 Diabetes in Germany and Its Association With Metabolic Control

PURPOSE

To investigate the psychosocial burden during the COVID-19 pandemic in adolescents with type 1 diabetes and its association with metabolic control.

METHODS

Prospective multicenter observational cohort study based on data from the German Diabetes Prospective Follow-up Registry. Adolescents aged 12-20 years with type 1 diabetes were asked during routine follow-up visits to complete a questionnaire on psychosocial distress and daily use of electronic media during the COVID-19 pandemic from June 2021 to November 2022. Well-being, anxiety, and depression symptoms were assessed using World Health Organization Five Well-Being Index (WHO-5), General Anxiety Disorder scale 7 (GAD-7), and Patient Health Questionnaire-9 questionnaires. The impact of mental health symptoms on metabolic control was analyzed by using multivariable linear regression models adjusted for sex, diabetes duration, treatment, socioeconomic deprivation, and immigrant background.

RESULTS

Six hundred eighty eight adolescents (45.6% females) from 20 diabetes centers participated. Compared with a prepandemic cohort, WHO-5 scores were lower during the COVID-19 pandemic (estimated mean difference -9.6 [95% confidence interval -11.6; -7.6], p < .001), but GAD-7 scores were not different (estimated mean difference 0.6 [95% confidence interval -0.2; 1.5], p = .14). HbA1c was significantly positively associated with GAD-7 and Patient Health Questionnaire-9 and negatively associated with WHO-5 scores (all p < .001). Daily electronic media use was positively associated with adjusted mental health symptoms (all p < .01).

DISCUSSION

Although the overall well-being of adolescents with type 1 diabetes was reduced during the later phase of the COVID-19 pandemic, the additional psychological burden was relatively low. However, mental health symptoms were associated with poorer metabolic control and higher use of electronic media.

Challenges During the Coronavirus Disease 2019 Pandemic: Diabetes Control and Psychosocial Issues in Children with Type 1 Diabetes Mellitus and Their Mothers

OBJECTIVE

Governments have enforced restrictions to prevent the spread of coronavirus dis- ease 2019, which has affected lifestyle and psychosocial well-being. The aim of this study is to examine the psychosocial dimensions of children with type 1 diabetes mellitus and lifestyle changes in the face of the pandemic.

MATERIALS AND METHODS

Sixty school-aged children with type 1 diabetes mellitus were included to evaluate socioeconomic status, lifestyle changes, and psychological state after a 3-month school closure, using a questionnaire as well as scales in children and mothers [Depression-Anx iety-Stress Scale (short-form), Revised Child Anxiety-Depression Scale (parent-version), The Perceived Stress Scale in Children] via a Google® Form. The effect of pre-pandemic glycemic control on lifestyle and factors affecting HbA1c change were also investigated.

RESULTS

The percentage of mothers having scale scores above the cutoff in terms of stress, anxiety, and depression were 18.3%, 23.3%, and 33.3%, respectively. Mother's and children's anxiety, depression, and stress scores were positively correlated. Employed mothers had higher depression scores. Paternal unemployment increased the anxiety of the mothers. Seventy-eight percent (n = 46) of the mothers thought that diabetes in their children increased the risk of coro- navirus disease 2019 infection, and children of these mothers had higher depression, anxiety, and stress scores(P = .01, P < .01, P < .01). The majority of participants were adversely affected by coronavirus disease 2019 in terms of daily routines and dietary compliance. Patients with poor-controlled type 1 diabetes mellitus deteriorated more in terms of diet compliance (P = .01).

CONCLUSION

Coronavirus disease 2019 affects the psychosocial dimensions in the family of chil- dren with type 1 diabetes mellitus. The psychosocial impact is reflected within the family and may affect diabetic control. Thus, it should be handled within the context of family. The provi- sion of proper information and guidance to parents may be crucial to alleviate the psychosocial burden on the family during the pandemic.

Disparities in Responsibility Sharing and Gender Differences in Diabetes Care: Changes in Occupational Life of Parents of Children with Type 1 Diabetes

Aims

To evaluate responsibility sharing between parents of children with type 1 diabetes and change in their occupational status one year after the diagnosis.

Methods

In this cross-sectional multicenter study, parents of children under the age of 18 with a diagnosis of type 1 diabetes answered a questionnaire assessing diabetes-related responsibility sharing between parents, and occupational changes due to child's diabetes. Changes in the occupational status with associated factors and distribution of diabetes-related responsibilities between parents were analyzed.

Results

Among parents of 882 children (mean (SD) age at diagnosis was 7 (3.8) years, female 52.5%), unemployment increased significantly in mothers (59.0% vs. 67.1%; p < 0.001), but not in fathers (10.4% vs. 10.7%; p > 0.05) within 1 year after their child's diagnosis. Working mother's occupational withdrawal was associated with the child's age at diagnosis (OR = 0.92, [95% CI 0.86-0.99]; p=0.02) and mother's education (compared to a university degree or above, high school graduate (OR = 2.93, [95% CI 1.59-5.4]; p < 0.001) and not graduated high school (OR = 8.4, [95% CI 3.56-19.83]; p < 0.001)). According to the mothers, none of the responsibilities in diabetes care were shared equally between parents, while fathers reported most responsibilities were shared equally. Compared to mothers who preserved their occupation after the diagnosis, mothers who quit their occupation had significantly higher responsibility scores (2.04 vs. 1.55; p=0.04), especially in diabetes care at school (p < 0.01).

Conclusions

The difference in parents' perceptions of their involvement in their child's diabetes is remarkable. Gender differences in the child's diabetes care extend to the occupational life of parents unequally.

Maternal depression or anxiety during pregnancy and offspring type 1 diabetes: a population-based family-design cohort study

INTRODUCTION

To investigate the association between maternal depression/anxiety during pregnancy and offspring type 1 diabetes, to assess the specific importance of exposure during pregnancy by comparing across different exposure periods before and/or after pregnancy, and to explore potential unmeasured familial confounding.

RESEARCH DESIGN AND METHODS

This was a population-based cohort including 1 807 809 offspring born in Sweden 2002-2019. From national registers, data were available on diagnosis or medication prescription for depression/anxiety in and around pregnancy, as well as incident cases of type 1 diabetes defined through diagnosis or insulin treatment. Associations were examined using flexible parametric and Cox regression models. Familial confounding was explored using paternal exposure as a negative control and by comparing offspring exposed to maternal depression/anxiety with their unexposed siblings.

RESULTS

For exposure during pregnancy, maternal depression/anxiety was associated with an increased risk of offspring type 1 diabetes onset after, but not before, 8 years of age (adjusted HR (aHR) 1.21 (95% CI 1.03 to 1.42]). Exposure occurring only during pregnancy was similarly associated to type 1 diabetes (aHR 1.24 (0.96 to 1.60)), whereas exposure occurring only before pregnancy was not (aHR 0.91 (0.64 to 1.30)). Associations were close to the null for paternal depression/anxiety (aHR 0.95 (0.72 to 1.25)), and point estimates were above 1 in sibling comparisons, although with wide CIs (aHR 1.36 (0.82 to 2.26)).

CONCLUSIONS

Maternal depression/anxiety specifically during pregnancy seems to be associated with offspring type 1 diabetes. Paternal negative control and sibling comparisons indicate that the results cannot entirely be explained by familial confounding.

Depressive and anxiety symptoms in adolescents with type 1 diabetes - a single-centre observational study

INTRODUCTION

Type 1 diabetes mellitus (T1DM) significantly affects the everyday functioning of the child and its family. This study aimed to assess the prevalence of symptoms of depression and anxiety and estimate their potential association with various clinical parameters.

MATERIAL AND METHODS

59 adolescents with T1DM (age 15-18) and their parents answered validated questionnaires (Children's Depression Inventory 2, The State-Trait Anxiety Inventory) and a survey assessing everyday functioning.

RESULTS

There were no significant differences in the occurrence of symptoms of depression in children and their parents (p = 0.975), but significant differences were found for anxiety. The distribution of the sten X1 and X2 values of adolescents and parents were different (p = 0.021 and p = 0.001, respectively). Girls were characterized by a higher level of depression both based on the overall score (p = 0.010) and the emotional problems (p = 0.022), and functional problems (p = 0.012). There was no significant correlation between diabetes duration time, glycaemic control, the occurrence of acute diabetes complications, and the parameters assessing anxiety and depression. Optimal glycaemic control, defined as HbA1c below 6.5% and TIR above 70%, was associated with sex (p = 0.001) and a high level of functional problems (p = 0.048).

CONCLUSIONS

In the studied population, adolescent girls with T1DM presented depressive symptoms more often than boys, and anxiety symptoms in adolescents were described more frequently by parents than by the teenagers themselves. Higher HbA1c was correlated with a higher level of functional problems.
