Introduction:
The role of gender as a parameter of smoking cessation is an area of interest

Material and Methods:
Information from patients that attended between 2006 and 2014 the UDESTA Tobacco Unit, dependent on the Government of Cantabria, were analyzed.During this period of time, 2052 women (54.4%) and 1722 men were treated.

Results:
Men and women differed in most of the variables that were analyzed. Although there were no differences in age (47.5 vs 48.1; p=0.10) or in the Fagerström test (6.2 vs 6.3; p=0.13), women tend to smoke less cigarettes (23.6 vs 27.2, p<0.001), find quitting harder (8.4 vs 8.0; p<0.001), refer less familiar support (8.2 vs 8.5; p<0.002), score higher in Goldberg-Depression (3.1 vs 2.6), in Goldberg-Anxiety Inventory (4.7 vs 4.2; p<0.001), and in the Perceived Stress Scale (16.2 vs 14.2; p<0.001). The prevalence of a psychiatric diagnosis was higher in women than in men (41 vs 35%; p<0.001); cannabis consumption was higher in men (2 vs 6%; p<.001).Despite these differences, cessation rates in men and women were absolutely similar at all the time periods analyzed: at quitting date (65.6 vs 63.6; p=0.21), at 6 months (40.4 vs 41.2; p=0.61), and at 12 months (32.2 vs 33.2; p=0.49).

Conclusions:
The absence of difference between sexes persist when data are adjusted either by age, psychiatric diagnosis, dependence, depression symptoms, perception of support, number of previous attempts, and drugs used during the treatment. The differences between sexes found in other studies might be due to the fact that in some other countries things are different, or that some confounding factors have not been ruled out.
