Background/Objectives: Patients with chronic myeloid leukemia (CML) have a long life expectancy due to modern treatment. However, treatment may have adverse effects that hamper work ability. Methods: Patients aged 25–60 years diagnosed in 2002–2020 were included in this nationwide matched cohort study examining work ability from diagnosis (index date), including the need for permanent disability compensation (flexible job or disability pension). Each patient was matched 1:5 on sex, birth year, and level of comorbidity with citizens from the general Danish population without CML. The risks of requiring flexible job and disability pension were calculated by cause-specific hazard ratios (HRs) using Cox proportional hazards regression, and the Aalen–Johansen estimator was used to determine cumulative risks. Results: A total of 489 patients with CML and 2445 matched comparators were included. The median age was 46 years, and males comprised 59.5% of the cohort. Matched comparators were more likely to work at index date and 1, 3, 5, and 10 years after the index date (p < 0.001). The HRs of requiring both flexible job (HR 8.7 (95% confidence interval (CI): 6.1;12.2, p < 0.001)) and disability pension (HR 3.7 (95% CI: 2.8;4.9, p < 0.001)) were higher among patients diagnosed with CML compared to matched comparators. The cumulative risk of requiring flexible job and disability pension also increased in patients with CML compared to matched comparators (p < 0.001). Conclusions: Patients with CML have a reduced work ability compared to the general population. More research is needed to determine the cause of their loss of ability to work.

Purpose: The study aims to explore the association between patients diagnosed with inflammatory bowel disease (IBD) in childhood or youth and mental health disorders. Methods: The study is a register-based cohort study of patients with IBD-onset before 25 years of age and matched references. They were followed until 30 years of age. The incidence rate and incidence rate ratio (IRR) for a wide spectrum of mental health disorders were assessed based on diagnostic codes from the Danish National Patient Registry, reimbursed prescriptions for psychotropic medications, and composite measures combining diagnosis and medication. Furthermore, the relative excess risk due to interaction (RERI) for parental educational level and parental mental health disorders were estimated. Results: A total of 4904 patients with Crohn’s disease (CD), 5794 with ulcerative colitis (UC), and 94,802 matched references were identified. Patients with CD-onset before age 18 had a higher risk of anxiety disorders (IRR 1.58 (CI95%: 1.33– 1.86)), while patients with CD-onset between age 18 to 24 had a higher risk of both anxiety and mood disorders. Patients with UC-onset before age 18 had a higher risk of anxiety disorders (IRR: 1.39 (CI95%: 1.19– 1.64)). In general, patients with IBD had a higher risk of receiving psychotropic medication. Parental education had a subadditive interaction with the risk of emotional disorders for both patients with CD and UC, while maternal mental health disorders had a subadditive interaction for patients with UC. Conclusion: Patients with CD and UC have a higher risk of mental health disorders, primarily due to an elevated risk of emotional disorders and a higher use of psychotropic medication. Surprisingly, the study demonstrated subadditive effect of parental education and for patients with UC maternal mental health disorders on the risk of emotional disorders.

Aim: Inflammatory bowel disease (IBD) diagnosed in adolescence may have adverse effects on educational attainment. The study aims to examine post‐secondary educational attainment in patients with IBD and how it is affected by disease severity and comorbid mental health disorders. Methods: This cohort study used nationwide Danish registries. In a cohort of patients with IBD and matched references, the time to attainment of post‐secondary education was examined using Cox regression. In the analysis for disease severity and mental health disorders, the relative risk of attainment of post‐secondary education was evaluated using binomial regression. Results: We identified 1136 patients with IBD and 8791 references. Overall, patients with Crohn's disease (CD) or ulcerative colitis (UC) attained a post‐secondary education as often as references (CD: hazard ratio (HR) 1.10 (95% confidence interval (CI) 0.99–1.22); UC: HR 0.97 (95% CI 0.88–1.06)). Patients with both severe IBD and mental health disorders had a significantly lower chance of attaining a post‐secondary education compared to patients with severe IBD without mental health disorders. Conclusions: Patients with IBD attained a post‐secondary education at the same rate as references. Having both severe IBD and mental health disorder negatively affected post‐secondary educational attainment.

Background and Aims: Only few studies have examined the socioeconomic consequences of being diagnosed with inflammatory bowel disease (IBD) in childhood or youth. Disease severity has been linked to lower earnings, but little attention has been paid to comorbid mental health conditions. The aim is to examine labor market participation (LMP) and income in patients with IBD onset in childhood or youth and examine how disease severity and mental health conditions affect LMP. Methods: In this register-based cohort study, we included patients with IBD onset before 25 years of age and matched comparators. We estimated the relative risk (RR) of having low LMP and the median yearly income from ages 26 to 30. RR of low LMP was also assessed in subgroups of patients based on disease severity (severe/nonsevere) and mental health conditions (yes/no). Results: A total of 3398 patients with IBD and 28 207 comparators were included. Overall, patients with IBD more often had low LMP (16.4% vs 14.4% in comparators), but slightly higher income (median yearly income difference at age 30: 1141 Euro [95% CI, 483-1798]). In subgroup analyses, only patients with severe IBD had a higher risk of low LMP (RR: 1.46 [95% CI, 1.23-1.72]), whereas patients with nonsevere IBD did not. Among patients with severe disease and mental health conditions, 46% had low LMP (RR: 5.03 [95% CI, 4.38-5.78]). Conclusions: Patients with IBD more often had low LMP, but their income was not affected. The subgroup of patients with severe disease and mental health conditions had the highest risk of low LMP.

Purpose: Most adult patients diagnosed with acute lymphoblastic leukemia (ALL) are below retirement age. The overall survival of patients with ALL has improved with implementation of high intensity pediatric-inspired treatment protocols. However, this treatment comes with a risk of long-term complications, which could affect the ability to work. The aim of this study was to investigate the risk of disability pension (DP) and return to work (RTW) for patients with ALL. Patients and Methods: Patients aged 18– 60 years diagnosed with ALL between 2005 and 2019 were identified in the Danish National Acute Leukemia Registry. Each patient was matched with five comparators from the general population on birth year, sex, and Charlson Comorbidity Index. The Aalen-Johansen estimator was used to calculate the cumulative risk of DP for patients and comparators from index date (defined as 1 year after diagnosis) with competing events (transplantation or relapse, death, retirement pension, or early retirement pension). Differences in cumulative incidences were calculated using Gray’s test. RTW was calculated as proportions one, three, and five years after the index date for patients holding a job before diagnosis. Results: A total of 154 patients with ALL and 770 matched comparators were included. The 5-year cumulative risk of DP was increased fivefold for patients with ALL compared with the general population. RTW was 41.7%, 65.7%, and 60.7% one, three, and five years after the index date, respectively. Conclusion: The risk of DP in patients with ALL increased significantly compared with the general population. Five years after the index date, RTW was 60.7% for patients with ALL.

Background: The obligation to pay for asthma medication in a country with universal healthcare might lead to increased asthma exacerbations and inequitable healthcare access for children from low-income households. Thus, the aim of this study was to examine the association between household income and childhood/preschool asthma regarding hospitalization and medication receipt. Methods: In this nationwide register-based cohort study, we encompassed all 3-year-old children residing in Denmark, born between 2000 and 2014, along with their linked parents and followed them until their sixth birthday. Household income was divided into quartiles. Asthma was categorized in two mutually exclusive groups as either the redemption of two prescriptions for asthma medication or receiving a hospital diagnosis. We utilized Poisson regression to estimate the risk ratio (RR). Results: The analysis included 834 422 preschool children. The prevalence of asthma dependent on medication alone was 7.3%, while 1.8% of children necessitated asthma-related hospitalization. Income inequality was evident across all income quartiles. Notably, children from the lowest income quartile had a RR of 0.95 (95% CI: 0.92–0.98) of redeeming asthma medication and conversely a RR of 1.18 (95% CI: 1.14–1.23) of asthma-related hospitalization. Conclusions: Despite universal healthcare, income inequality has a dual impact on children from low-income households. They face a diminished risk of redeeming asthma medication and a higher susceptibility to asthma-related hospitalizations indicating an unequal access to healthcare. Prioritizing efforts to reduce childhood health inequalities is crucial. However, further research, particularly qualitative studies, is needed to better comprehend the underlying mechanisms to address the complexities of income inequality.

Educational achievement may be adversely affected by chronic conditions in childhood and adolescence. This study aimed to examine the effect of being diagnosed with IBD on achievement of an upper secondary education and the influence of disease severity and psychiatric comorbidity. This cohort study was based on nationwide Danish administrative registries. We compared a cohort of patients with IBD with a matched population-based cohort. The IBD cohort included patients born between 1970 and 1994 who were diagnosed with IBD (age n = 1344, ulcerative colitis [UC] n = 1834) and matched them with 28 204 references. The hazard ratio of achieving an upper secondary education was 1.14 (95% confidence interval, 1.07-1.21) for CD and 1.16 (95% confidence interval, 1.10-1.23) for UC. In the IBD cohort, having surgery, a steroid prescription, or a comorbid psychiatric condition was associated with a lower chance of achieving an upper secondary education. Being diagnosed with IBD before 18 years of age increased the chance of achieving an upper secondary education. However, patients with more severe disease or psychiatric comorbidity were at higher risk of not achieving an upper secondary education than patients with milder disease.

Background: Children with the most severe parental mental health conditions have an elevated risk of numerous adversities including somatic morbidity. However, there is no knowledge concerning physical health in most children affected by parental mental health conditions. Therefore, the aim was to examine the association between different severities of parental mental health conditions and somatic morbidity in children of different age-groups and further explore the combinations of maternal and paternal mental health conditions on child somatic morbidity. Methods: In this register-based cohort study, we included all children born in Denmark between 2000–2016 and linked parents. Parental mental health conditions were categorised into four severity groups (no, minor, moderate, and severe). Somatic morbidity in offspring was categorised into broad disease categories corresponding to the International Classification of Diseases. We estimated the risk ratio (RR) using Poisson regression, of the first registered diagnosis in different age-groups. Results: Of the around 1 million children in the study > 14.5% were exposed to minor parental mental health conditions and < 2.3% were exposed to severe parental mental health conditions. Overall, the analyses revealed a higher risk of morbidity in exposed children across all disease categories. The strongest association was observed for digestive diseases in children aged < 1 year exposed to severe parental mental health conditions (RR: 1.87 (95% CI: 1.74–2.00). Generally, the risk of somatic morbidity increased the more severe the parental mental health conditions. Both paternal and especially maternal mental health conditions were associated with a higher risk of somatic morbidity. The associations were strongest if both parents had a mental health condition. Conclusion: Children with different severities of parental mental health conditions experience a higher risk of somatic morbidity. Although children with severe parental mental health conditions had the highest risk, children with minor parental mental health conditions should not be neglected as more children are exposed. Children with both parents having a mental health condition were the most vulnerable to somatic morbidity and maternal mental health conditions were more strongly associated with somatic morbidity than paternal. More support and awareness of families with parental mental health conditions is highly needed.

Purpose: Many patients diagnosed with lymphoma are of working age. Cancer patients are known to have a higher risk of sick leave and disability pension, but this has only been delineated for certain subtypes of lymphoma. Therefore, this study aimed at investigating the overall risk of disability pension for all lymphoma subtypes and at quantifying return to work for patients with lymphoma in work before diagnosis. Patients and Methods: Patients aged 18– 60 years with lymphoma in complete remission (CR) diagnosed between 2000 and 2019 were included in the study. Using national registers, each patient was matched with five comparators from the general population with same sex, birth year, and level of Charlson Comorbidity Index. Risk of disability pension was calculated from 90 days after CR or end of treatment with competing events (death, retirement pension, early retirement pension, relapse for patients, or lymphoma diagnosis for comparators). Return to work for patients was calculated annually until 5 years after diagnosis for patients employed before diagnosis. Results: In total, 4072 patients and 20,360 comparators were included. There was a significant increased risk of disability pension for patients with all types of lymphoma compared to the general population (5-year risk difference: 5.3 (95% confidence interval (CI): 4.4;6.2)). Patients with non-Hodgkin lymphoma were more likely to get disability pension than patients with Hodgkin lymphoma (sex- and age-adjusted 10-year risk difference: 2.9 (95% CI: 0.3;5.5)). One year after diagnosis, 24.5% of the relapse-free patients were on sick leave. Return to work was highest 2 years after diagnosis (82.1%). Conclusion: Patients with lymphoma across all subtypes have a significantly higher risk of disability pension. Return to work peaks at 2 years after diagnosis.

BACKGROUND: In Denmark, people with permanent and significantly reduced work capacity can be assigned to a flexi-job (FJ) scheme. In 2013, the social security policy for FJ was reformed to improve employment possibilities for people with reduced work capacity. OBJECTIVE: To describe work participation in the FJ scheme before and after the reform in the North Denmark Region. METHODS: The study population was assigned to the FJ scheme between 2010 and 2015 and followed for two years. Work participation score (WPS) was defined as the number of working weeks divided by the total number of weeks in the FJ scheme. High WPS was defined as above the median. RESULTS: A total of 4,668 people were included in the study. High WPS was significantly influenced by enrolment after policy changes (odds ratio (OR)) 1.60, 95% CI 1.41–1.81), male sex (OR 1.20, CI 1.06–1.36), age above 50 (OR 0.72, CI 0.58–0.90), peripheral living (OR 0.75, CI 0.63–0.90), contact to both somatic and psychiatric healthcare (OR 0.55, CI 0.43–0.71) and a prior strong association to the labour market (OR 5.70, CI 4.40–7.37). CONCLUSIONS: Policy changes increased work participation in the FJ scheme.
