Objectives: We evaluated the risk of work disability (sick leave and disability pension) before and after diabetes diagnosis relative to individuals without diabetes during the same time period, as well as the trajectory of work disability around the diagnosis.
Methods: This Swedish population-based cohort study with register data included 14 428 individuals with incident diabetes in 2006 and 39 702 individuals without diabetes during 2003 to 2009.
Results: Work disability was substantially higher among people with diabetes (overall mean = 95 days per year over the 7 years, SD = 143) than among those without diabetes (mean = 35 days, SD = 95). The risk of work disability was slightly higher after diabetes diagnosis than before and compared with the risk of those without diabetes. The trajectory of work disability was already increasing before diagnosis, increased even more at the time of diagnosis, and leveled off after diagnosis. Individual sociodemographic characteristics and comorbid conditions contributed both to the risk and to the trajectory of work disability.
Conclusions: Although diabetes has an independent effect on work disability, sex, age, education, and comorbid conditions play a significant role.
