[Changes in behaviors and indicators of mental health between 2006 and 2010 in the French working population]

The 2008 economic crisis may have had an impact on mental health but the studies on this topic are sparse, in particular among the working population. However, mental health at work is a crucial issue involving substantial costs and consequences. The aim of the study was to assess changes in behaviors and indicators of mental health in the French working population between 2006 and 2010, and to explore the differential changes according to age, origin, occupation, activity sector, public/private sector, self-employed/employee status and work contract.

The data came from the prospective national representative Santé et itinéraire professionnel (SIP) survey, including a sample of 5600 French workers interviewed in 2006 and 2010. The behaviors and indicators of mental health studied were excessive alcohol consumption, smoking, sleep problems (sleep disorders and/or insufficient sleep duration), psychotropic drug use (antidepressants, anxiolytics and/or hypnotics), and poor self-reported health. Generalized estimating equations were used to analyze changes in behaviors and indicators of mental health, and the analyses were adjusted for age. Covariates (age, origin, occupation, activity sector, public/private sector, self-employed/employee status and type of contract) were added separately to assess differential changes.

Increases in excessive alcohol consumption among women, sleep problems among men, and smoking, insufficient sleep duration and poor self-reported health for both genders were observed in the French working population between 2006 and 2010. Some differential changes were observed, negative changes being more likely to affect young workers and workers with a permanent contract.

Prevention policies should consider that behavior and indicators of mental health may deteriorate in times of economic crisis, especially among some sub-groups of the working population, such as young workers and workers with a permanent contract. These changes might foreshadow a forthcoming increase in mental disorders.
