The joint contribution of diabetes and work disability to premature death during working age: a population-based study in Sweden.

AIMS: We aimed to examine how newly diagnosed diabetes and work disability jointly predict death during working age.

METHODS: We used prospective population-based register data of 25-59-year-old adults who had lived in Sweden since 2002. All those with onset of diabetes recorded in 2006 were included (n=14266). A 2% random sample (n=78598) was drawn from the general population, comprising people with no indication of diabetes during 2003-2010. Net days of sickness absence and disability pension in 2005-2006 were examined; the follow-up time for mortality was 2007-2010. Cox regression models were fitted (hazard ratios, HR, 95% confidence interval, CI) adjusting for sociodemographics and time-dependent health conditions.

RESULTS: Individuals with diabetes and work disability for over 6 months were at a higher risk of premature death (HR=14.2, 95% CI 12.0-16.8) than their counterparts without diabetes and work disability. A high risk was also observed among people without diabetes but equally prolonged work disability (HR=6.4, 95% CI 5.4-7.6). Diabetes was associated with premature death even without work disability (HR=3.5, 95% CI 2.8-4.4). The associations were particularly attenuated after adjustment for health conditions assessed over the follow-up.

CONCLUSIONS: DIABETES AND WORK DISABILITY JOINTLY INCREASE THE RISK OF DEATH DURING WORKING AGE DIABETES WITH LONG-TERM WORK DISABILITY IS ASSOCIATED WITH THE HIGHEST RISK OF PREMATURE DEATH, WHICH HIGHLIGHTS THE IMPORTANCE OF THEIR PREVENTION AND EARLY DETECTION.
