Common Mental Disorders and Sickness Absence: A Register-Linkage Follow-Up Study Among Finnish Municipal Employees.

Abstract

This study examined how common mental disorders (CMD) at different severity levels are associated with short (1 to 3-day), intermediate (4 to 14-day), and long (15+ day) sickness absence (SA) among Finnish municipal employees. Survey data collected among the 40 to 60-year-old employees of the City of Helsinki in 2000 to 2002 were prospectively linked with employer's SA register data (N = 6554). Associations of CMD (GHQ-12) with SA in a 5-year follow-up were examined with quasi-Poisson regression. Increasing GHQ-12 scores were associated with a higher number of SA spells. The highest GHQ-12 scores were associated with the highest number of short, intermediate, and long SA spells. Adjusting for social and health-related covariates attenuated the associations but they remained. Increasing severity of CMD increased the risk of short, intermediate, and long SA among Finnish employees. CMD should be tackled to prevent SA and promote work-ability among aging employees.
