Impact of Diabetes on Work Cessation

Abstract

OBJECTIVETo measure the impact of diabetes on work cessation, i.e., on the risks of work disability, early retirement, and death while in the labor force.RESEARCH DESIGN AND METHODSWe used data from the GAZEL prospective cohort of 20,625 employees of the French national gas and electricity company “EDF-GDF.” We identified 506 employees with diabetes and randomly selected 2,530 nondiabetic employed control subjects matched for major sociodemographic and occupational characteristics. Using a multistate Cox model, we estimated hazard ratios (HRs) comparing the risks of transition from employment to disability, retirement, and death over time between participants with versus without diabetes.RESULTSEmployment rate decreased more rapidly in participants with diabetes (51.9 and 10.1% at 55 and 60 years, respectively) compared with nondiabetic participants (66.5 and 13.4%, respectively). Participants with diabetes had significantly increased risks of transition from employment to disability (HR 1.7 [95% CI 1.0–2.9]), retirement (HR 1.6 [1.5–1.8]), and death (HR 7.3 [3.6–14.6]) compared with participants without diabetes. Between 35 and 60 years, each participant with diabetes lost an estimated mean time of 1.1 year in the workforce (95% CI 0.99–1.14) compared with a nondiabetic participant.CONCLUSIONSOur results provide evidence for a profound negative impact of diabetes on workforce participation in France. Social and economic consequences are major for patients, employers, and society—a burden that is likely to increase as diabetes becomes more and more common in the working-aged population.
