Depression and change in occupational functioning in type 2 diabetes

A prospective cohort study of presenteeism and increased risk of unemployment among Japanese workers during the COVID-19 pandemic

OBJECTIVES

Presenteeism adversely affects workers' quality of life, leading to further deterioration of their health and affecting their ability to continue working. Unemployment is one of the most serious consequences for workers experiencing presenteeism. A worker's ability to work depends on the degree of mismatch between their health status and job demands and work factors. The COVID-19 pandemic has affected workers' experiences of presenteeism as well as their employment status. We examined the association between presenteeism and risk of job resignations and unemployment among Japanese workers during the COVID-19 pandemic.

METHODS

A prospective study of 27 036 internet monitors was conducted, starting in December 2020, with 18 560 (68.7%) participating in the follow-up by December 2021. The Work Functioning Impairment Scale (WFun) was used to measure the degree of work function impairment.

RESULTS

The group with the highest WFun scores had higher odds ratios (ORs) for both retirement and unemployment for health reasons than the group with the lowest WFun scores. ORs were 2.99 (95% CI, 2.48-3.62; P < .001) and 1.82 (95% CI, 1.65-2.00; P < .001), respectively.

CONCLUSIONS

Workers with work functioning impairment are at increased risk of resignation or unemployment. Management strategies for workers with work functioning impairment are needed to reduce their disadvantages in employment.

Self-reported work productivity in people with multiple sclerosis and its association with mental and physical health

PURPOSE

This study aimed to identify mental health, physical health, demographic and disease characteristics relating to work productivity in people with multiple sclerosis (MS).

METHODS

In this cross-sectional study, 236 employed people with MS (median age = 42 years, 78.8% female) underwent neurological and neuropsychological assessments. Additionally, they completed questionnaires inquiring about work productivity (presenteeism: reduced productivity while working, and absenteeism: loss of productivity due to absence from work), mental and physical health, demographic and disease characteristics. Multiple linear and logistic regression analyses were performed with presenteeism and absenteeism as dependent variables, respectively.

RESULTS

A model with mental and physical health factors significantly predicted presenteeism F(11,202) = 11.33, p < 0.001, R² = 0.38; a higher cognitive (p < 0.001) and physical impact (p = 0.042) of fatigue were associated with more presenteeism. A model with only mental health factors significantly predicted absenteeism; χ²(11)=37.72, p < 0.001, with R² = 0.27 (Nagelkerke) and R² = 0.16 (Cox and Snell). Specifically, we observed that more symptoms of depression (p = 0.041) and a higher cognitive impact of fatigue (p = 0.011) were significantly associated with more absenteeism.

CONCLUSIONS

In people with MS, both cognitive and physical impact of fatigue are positively related to presenteeism, while symptoms of depression and cognitive impact of fatigue are positively related to absenteeism.Implications for rehabilitationMultiple sclerosis (MS) affects people of working age, significantly interfering with work productivity.Higher cognitive and physical impact of fatigue were associated with more presenteeism in workers with MS.A higher cognitive impact of fatigue and more depressive symptoms were associated with absenteeism in workers with MS.Occupational and healthcare professionals should be aware of the impact of both physical and mental health on work productivity in workers with MS.

SITAgliptin for Depressive Symptoms in Type 2 Diabetes: A Feasibility Randomized Controlled Trial

OBJECTIVE

We tested the feasibility of using sitagliptin-a dipeptidyl peptidase-IV inhibitor-for depressive symptoms in type 2 diabetes (T2D).

METHODS

In a feasibility, double-blind, randomized controlled trial, we recruited people aged 18 to 75 years with T2D (glycated hemoglobin A1c levels ≥53 and ≤86 mmol/mol prescribed oral hypoglycemic therapy) and comorbid depressive symptoms (Patient Health Questionnaire-9 score ≥10) from family practices in South London. Eligible patients were randomized to sitagliptin 100 mg per day or matched placebo for 12 weeks. The primary feasibility outcomes were participation rates, attrition rates, and adverse events. The primary clinical outcomes were depressive symptoms (Patient Health Questionnaire-9 and 16-item Quick Inventory of Depressive Symptomatology scores) at 12 weeks as assessed using analyses of covariance. Ranges of treatment effects were estimated using Cohen d and associated 95% confidence intervals, where negative values favored sitagliptin over placebo.

RESULTS

Of 153 people screened across 32 practices, 44 were randomized (22 to each arm). The mean (standard deviation) age was 58.8 (8.3) years, 46% were female, and 52% were of non-white ethnicity. Of those treated, 1 patient (4.5%) in each arm withdrew, and there were no group differences in adverse events. Despite improving 12-week glycated hemoglobin A1c (d = -1.19 [95% confidence interval = -1.90 to -0.48), improvement in 12-week Quick Inventory of Depressive Symptomatology score with sitagliptin was inferior to placebo across the range of estimated treatment effects (d = 0.71 [0.13 to 1.30]). Effects of sitagliptin on inflammation were inconsistent (d = -0.32 [-0.81 to 0.17] for high-sensitivity C-reactive protein).

CONCLUSIONS

Repositioning of oral hypoglycemic therapy for depressive symptoms in T2D is feasible. However, in this unpowered feasibility study, we did not detect evidence of superiority of sitagliptin over placebo. The results are cautioned by the small sample size and limited treatment duration.Trial Registration: EudraCT: 2015-004527-32.

Factors associated with work ability in adults with diabetes

AIMS

The aims of this study were to explore associations between clinical and diabetes-related factors with work ability in a sample of working adults with diabetes.

BACKGROUND

Adults with diabetes may face challenges in the workplace, including managing their diabetes and overall physical and mental health.

METHODS

This was a cross-sectional design with a sample of 101 working adults. Subjects completed valid and reliable surveys assessing depressive symptoms, diabetes self-care, fear of hypoglycemia, diabetes distress, cardiovascular health using American Heart Association's Life's Simple 7 (range 0-7) and work ability. Factors significantly associated with work ability at bivariate level were included in linear and logistic regression.

RESULTS

The majority of the sample was female (65%) (mean age 54.1 ± 10.5), White (74%), non-Hispanic (93%), worked full-time (65%) and had type 2 diabetes (87%) (mean duration 12.4 ± 9.5 years). The majority (55%) had low diabetes distress, but 24% had high distress and 28% had depressive symptoms. The sample achieved 2.5 ± 1.4 ideal AHA heart health indices and 33% rated their work ability as excellent. In linear regression higher depressive scores were associated with lower work ability scores (b = -0.45, p = .002). In logistic regression, scores on heart health (OR = 1.4; 95%CI:1.0-1.9, p = .03) and diabetes distress (OR = 0.6, 95%CI:0.4-0.9, p = .048) were significantly associated with work ability at its best.

CONCLUSION

Both cardiovascular and psychological health may impact work ability in adults with diabetes. Routinely screening for diabetes distress and depression while also promoting ideal cardiovascular health may improve overall health and work ability in this population.
