[Sick leave due to tobacco use in workers aged 35-64. Catalonia, 2007-2016].

Objective: Few recent studies have researched into the size and trends of the impact of tobacco use on productivity losses. The objective of this work was to describe the percentage of episodes and non work-related sick leave days with a duration over 5 days due to tobacco use in Catalonia in the period 2007-2016 in relation to the total sick-leave episodes and sick leave days in patients aged 35-64.

Methods: Descriptive study of 3,627,107 episodes and 237,219,230 days in sick-leave by any cause, except those work-related, in workers aged 35-64. Population etiological fractions were used. The annual percentage of number of episodes and sick-leave days due to tobacco use in relation with total episodes and sick-leave days was calculated and a trend test was performed.

Results: The percentage of sick-leave episodes and days due to tobacco use was higher in men (3.9%; 5.5% respectively) than in women (2.3%; 1.5% respectively). The trend for sick-leave due to tobacco use was positive, with a maximum OR in 2013. For the number of sick-leave episodes due to tobacco use, the corrected Z was 25.3 in men (p<0.001) and 49.4 in women (p<0.001). For sick-leave days due to tobacco use, the corrected Z was 36.9 in men (p<0.001) and 250.4 in women (p< 0.001).

Conclusions: About 3% of sick-leave episodes with a duration over than 5 days are due to tobacco use, with a positive trend in both sexes. It is necessary to continue reinforcing the tobacco prevention and control policies in order to improve such trends for years to come.
