Do poor health behaviors have an impact on the transition from sick leave to disability pension?

Abstract

Abstract Background High age, being a woman, and having low socioeconomic status are among the important risk factors for transitioning from sickness absence (SA) to disability pension (DP). But, little is known about the effect of poor health behaviors, although there are indications that poor health behaviors increase the risk of both SA and DP. The aims were to study the associations between three poor health behaviors (current smoking, high alcohol consumption and low physical activity levels) and DP among individuals who recently been sickness absent, and to explore whether having multiple poor health behaviors increased the risk of transitioning from SA to DP. Methods This prospective cohort study included 1991 twin individuals aged 20-46 who participated in a survey in 2005 and who had been on long-term SA in the two years preceding baseline (date of answering the survey) data collection of health behaviors (smoking, alcohol and physical activity) and relevant covariates. The participants were followed up for incident all-cause DP until the 31st of December 2012 (mean follow-up 5.2 years). National register data of SA and DP were used, and the association between each health behavior and DP was estimated using Cox proportional hazards regression analyses. The results are presented as Hazard Ratios (HR) with 95% Confidence Intervals (CI). Results Results showed that compared to never smoking, current smoking was associated with a higher risk of transitioning from SA to DP (HR 1.76, 95%CI 1.08-2.84). Alcohol use, lack of physical activity or having several poor health behaviors showed no significant associations. Conclusions Being a current smoker influences the risk of transitioning from SA to DP. Poor health behaviors are well established risk factors for poor physical and mental health. Hence, from a public health perspective it is important to emphasize the value of improving health behaviors in general but also among people with a history of SA. Key messages Many factors including health behaviors influence the risk of transitioning from sickness absence to permanent work incapacity in terms of disability pension. Supporting people on sickness absence to improve their health behaviors, e.g. smoking cessation, could be a promising approach to prevent exit from the labor market through disability pension.
