Diabetes mellitus and its association with work patterns and characteristics: a narrative review.

Diabetes mellitus is a leading cause of disability with adverse effect on the quality of life. It also affects occupational health by impacting on several work parameters. The aim of this narrative review is to discuss the relationship between diabetes and absenteeism, presenteeism, work impairment and unemployment. The association between work and diabetic complications such as neuropathic pain, diabetic foot, psychological issues and hypoglycemia due to treatment is also examined. Evidence points to a relationship of diabetes with absenteeism, reduced work productivity and, thus, overall work impairment. A stronger negative impact on work performance is mediated by painful diabetic neuropathy and diabetic foot. In addition, psychological distress has been positively correlated with total workdays lost and frequency of absence. Depression in the diabetic population has also been linked with increased absenteeism, presenteeism and work disability. Moreover, hypoglycaemia induced by antidiabetic medication may affect work attendance and performance. Finally, diabetes has been associated with inequality in the work environment, lower job satisfaction and higher unemployment rates, mainly because of its complications.
