[Occupational factors associated with suicide among French employees from the special agricultural social security scheme (MSA) working between 2007 and 2013].

Background: Work and related exposures may play a role in suicide and there has been evidence in the literature that some occupational factors may be associated with suicide. The identification of occupational risk factors of suicide mortality among employees affiliated to the French special agricultural social security scheme (MSA), an understudied population, appears important. The objective of this study was to identify the occupational factors associated with suicide mortality among French employees from the MSA working between 2007 and 2013.
Methods: The study population included all the employees affiliated to the MSA working between 1st January 2007 and 31st December 2013, i.e. 1,699,929 men and 1,201,017 women. The studied occupational factors included: economic activity, skill level, and work contract. Survival analyses (Cox models) stratified on gender were performed using age as time scale and region and year of contract as adjustment variables.
Results: Among men, the factors associated with an elevated suicide risk were: economic activities of forestry, agriculture and related activities, and manufacture of food products and beverages (e.g. meat, wine), low-skilled level and working in the regions of Brittany, Burgundy Franche-Comté, Pays de la Loire, Normandy, Grand Est and Centre-Val-de-Loire. No association was observed among women.
Conclusion: These results suggest that economic activity and low-skilled level may be associated with suicide among men affiliated to the MSA and may contribute to the implementation of prevention interventions. Further studies are needed to confirm and better understand these associations.
