Insulin Pump Treatment in Adults with Type 1 Diabetes in the Capital Region of Denmark: Design and Cohort Characteristics of the Steno Tech Survey.

INTRODUCTION: Insulin pump therapy can improve quality of life and glycaemic outcomes for many people with type 1 diabetes (T1D). The multidimensional Steno Tech Survey study aims to investigate why some insulin pump users do not achieve treatment goals. In this article, we present the study design and analyse differences in population characteristics between responders and non-responders. METHODS: In June 2020, all 1591 insulin pump users (≥ 18 years) in the Capital Region of Denmark were invited to participate in an online questionnaire that evaluated several dimensions of insulin pump self-management and psychosocial health. Demographic, socioeconomic and clinical characteristics, including age, sex and HbA1c, of the cohort were identified via national registries. Predictors of questionnaire response/non-response were explored with logistic regression analysis. RESULTS: In the full study population, 58% were female, median age was 42 years and median HbA1c was 58 mmol/mol (7.5%); 30% had HbA1c < 53 mmol/mol (7.0%). In total, 770 individuals (48%) responded to the questionnaire. Logistic regression analysis showed that 50+ years of age (odds ratio [OR] = 2.3, 95% confidence interval [CI]: 1.4-3.8), female sex (OR = 1.3, CI: 1.02-1.6), being married (OR = 1.8, CI: 1.3-2.4) and having long higher education (OR = 1.6, CI: 1.004-2.5) were significantly associated with a higher likelihood of responding to the survey; the opposite was found for HbA1c from 64 to < 75 mmol (8.0-9.0%) (OR = 0.6, CI: 0.4-0.8) and HbA1c ≥ 75 mmol/mol (≥ 9.0%) (OR = 0.2, CI: 0.1-0.3). CONCLUSIONS: The established Steno Tech cohort enables future analysis of a range of psychosocial and behavioural aspects of insulin pump self-management. Interpretation and generalization of findings should consider observed differences between responders and non-responders.

Working life expectancies among individuals with type 1 and type 2 diabetes over a 30-year period.

OBJECTIVES: This study aimed to (i) estimate working life expectancies (WLE) and the number of working years lost (WYL) among individuals with type 1 and type 2 diabetes over a 30-year period and (ii) identify educational differences in WLE and WYL. METHODS: Individuals aged 18-65 years diagnosed with type 1 (N=33 188) or type 2 diabetes (N=81 930) in 2000-2016 and age- and gender-matched controls without diabetes (N=663 656) were identified in Danish national registers. WLE in years were estimated as time in employment from age 35-65 years. We used a life-table approach with multi-state (eg, disability pension, sickness absence, unemployment) Cox proportional hazard modeling. Analyses were performed separately for sex, cohabitation status, educational duration, and type of diabetes. Inverse probability weights accounted for differences between populations. RESULTS: People with diabetes had significantly shorter WLE and greater WYL compared to people without diabetes over the 30-year span. At age 35, cohabitant women with lower education and diabetes lost up to 8.0 years [95% confidence interval (CI) 5.0-11.0] and men 7.0 years (95% CI 4.0-8.7). WYL among women with higher education was 4.4 (95% CI 6.6-2.3) and 3.7 years among men (95% CI 1.5-4.5). Compared to people with type 2 diabetes, those with type 1 spend significantly more years in disability pension, but there were no significant differences in the other WYL estimates. CONCLUSIONS: The WYL among people with diabetes is substantial and characterized by social disparities. The WYL help identify intervention targets at different ages, types of diabetes, sex, educational and cohabitant status.

Conflicting Logics in a Changing Action Space: Challenges Related to Type 1 Diabetes in Work Life.

Well-being at work is important to quality of life. However, reconciling work and diabetes management is often challenging; failing to do so threatens the well-being of people with type 1 diabetes (T1D). We explored the mechanisms underlying diabetes-specific challenges at work using theories of logics, involvement, and action space. Thematic analyses of two data sets, consisting of interviews with adults with T1D (n = 22) showed that people with T1D experience a conflict between two logics linked to diabetes and work, owing to the contradictory demands of work life and diabetes management. Individuals' ability to lower the priority of work tasks-shifting them from their main to a side involvement so as to properly manage T1D-helps resolve the conflict, as does being able to create an enabling action space for diabetes management at work. These insights can inform interventions targeting the well-being of workers with T1D.

Effort-reward imbalance at work and risk of type 2 diabetes in a national sample of 50,552 workers in Denmark: A prospective study linking survey and register data.

OBJECTIVE: To examine the prospective relation between effort-reward imbalance at work and risk of type 2 diabetes. METHODS: We included 50,552 individuals from a national survey of the working population in Denmark, aged 30-64 years and diabetes-free at baseline. Effort-reward imbalance was defined, in accordance with the literature, as a mismatch between high efforts at work (e.g. high work pace, time pressure), and low rewards received in return (e.g. low recognition, job insecurity) and assessed as a continuous and a categorical variable. Incident type 2 diabetes was identified in national health registers. Using Cox regression we calculated hazard ratios (HR) and 95% confidence intervals (95% CI) for estimating the association between effort-reward imbalance at baseline and risk of onset of type 2 diabetes during follow-up, adjusted for sex, age, socioeconomic status, cohabitation, children at home, migration background, survey year and sample method. RESULTS: During 136,239 person-years of follow-up (mean = 2.7 years) we identified 347 type 2 diabetes cases (25.5 cases per 10,000 person-years). For each one standard deviation increase of the effort-reward imbalance score at baseline, the fully adjusted risk of type 2 diabetes during follow-up increased by 9% (HR: 1.09, 95% CI: 0.98-1.21). When we used effort-reward imbalance as a dichotomous variable, exposure to effort-reward imbalance was associated with an increased risk of type 2 diabetes with a HR of 1.27 (95% CI: 1.02-1.58). CONCLUSION: The results of this nationwide study of the Danish workforce suggest that effort-reward imbalance at work may be a risk factor for type 2 diabetes.

Changes in effort-reward imbalance at work and risk of onset of sleep disturbances in a population-based cohort of workers in Denmark.

OBJECTIVE/BACKGROUND: Associations between exposure to effort-reward imbalance at work (eg, high time pressure/low appreciation) and risk of sleep disturbances have been reported, but the direction of the effect is unclear. The present study investigated changes in effort-reward imbalance and risk of concomitant and subsequent onset of sleep disturbances. METHODS: Participants with sleep disturbances at baseline were excluded. We included participants from a population-based cohort in Denmark (n = 8,464, 53.6% women, mean age = 46.6 years), with three repeated measurements (2012 (T0); 2014 (T1); 2016 (T2)). Changes in effort-reward imbalance (T0-T1) were categorized into 'increase', 'decrease' and 'no change'. Self-reported sleep disturbances (difficulties initiating or maintaining sleep, non-restorative sleep, daytime tiredness) were dichotomized (presence versus absence). We regressed concomitant (T1) and subsequent (T2) sleep disturbances on changes in effort-reward imbalance (T0-T1) and calculated odds ratios (OR) and 95% confidence intervals, adjusted for sex, age, education and cohabitation. RESULTS: At follow-up, 8.4% (T1) and 12.5% (T2) reported onset of sleep disturbances. Increased effort-reward imbalance was associated with concomitant sleep disturbances (T1) (OR = 3.16, 2.56-3.81), whereas decreased effort-reward imbalance was not (OR = 1.22, 0.91-1.63). There was no association between increased effort-reward imbalance and subsequent sleep disturbances (T2) (OR = 1.00, 0.74-1.37). Results were similar for men and women. CONCLUSIONS: Increased effort-reward imbalance was associated with a three-fold higher risk of concomitant onset of sleep disturbances at two-year follow-up, but not subsequent onset of sleep disturbances at four-year follow-up, indicating that changes in effort-reward imbalance have immediate rather than delayed effects on sleep impairment. It is possible that the results from the two-year follow-up were to some extent affected by reverse causality.

Exploring the experiences of people with hypo- and hyperthyroidism.

Thyroid diseases evoke a complex range of psychological and physical symptoms. The psychosocial aspects of living with diseases causing hypo- or hyperthyroidism are poorly understood. In this article, we report the findings of a qualitative interview study in which we explored the lived experiences of 16 people with hypo- or hyperthyroidism. We purposefully selected participants from Danish outpatient clinics according to their diagnosis (Hashimoto's thyroiditis or Graves' disease with or without orbitopathy), age (18 to 65 years), and duration of treatment (more than 6 months). We used interpretative phenomenological analysis (IPA) as a theoretical frame and analytical approach and identified three superordinate themes: losing control over mental and physical states, ambiguous signs of disease, and negotiating sickness. We discuss the findings in the context of the recent literature on chronic illness and argue that these themes play an important role in the conceptualization and management of thyroid diseases.

Work-related factors and early retirement intention: a study of the Danish eldercare sector.

BACKGROUND: Western countries are experiencing an ageing and shrinking workforce in the eldercare sector. This study investigated whether 12 different work-related factors are associated with early retirement intentions of employees in the Danish eldercare sector. We tested whether three hypotheses explained the increase of early retirement intention: (i) high job demands (four factors) and low resources (four factors); (ii) low job attitude (three factors); and (iii) high physical strain (one factor). METHODS: We included 2444 employees (aged 45-57 years) from two waves (T1 and T2) from a prospective study. Multinomial logistic regression models showed whether 12 work-related factors (T1) were associated with early retirement intention (T2); very early retirement intention and early retirement intention vs. normal retirement intention. RESULTS: Only 14% of the participants wished to retire at the normal retirement age (65 years or older). High physical strain [hypothesis (iii)] and low and normal affective organizational commitment [hypothesis (ii)] were associated with very early retirement intention. None of the other work-related factors associated with early retirement intention. CONCLUSIONS: Future interventions should focus on reducing physical strain and increase or maintain affective organizational commitment among employees in the eldercare sector to postpone retirement.
