Work ability among Finnish workers with type 1 diabetes

Background Work ability represents the balance between individual resources, health status and job demands. As far as we are aware, these issues have not been examined in working people with type 1 diabetes (T1D). Aims To examine how work-related and diabetes-related factors are associated with work ability among male and female workers. Methods Questionnaires were mailed to a random sample of 2500 people with T1D from the Medication Reimbursement Register of The Social Insurance Institution of Finland. The associations of the predictors of poor work ability were examined in a logistic regression analysis. Results The final sample comprised 767 working people aged 18-64 with T1D; overall response rate 49%. One in every three working men and women with T1D had poor work ability. High job demands and low job control were associated with poor work ability in both genders. Physical work and low worktime control were significantly associated with poor work ability in men but not in women with T1D. A self-reported high value of glycosylated haemoglobin was the only diabetes-related variable associated with poor work ability in both men and women. Conclusions Work-related factors and poor glycaemic control were associated with poor work ability in individuals with T1D. Thus, job control and worktime control should be taken into account in supporting the work ability of workers with T1D.
