Smokers Have A 41 Percent Higher Risk Of Suffering Depression

The article, whose first author is Prof. Almudena Sánchez-Villegas, is based on research undertaken over the course of 6 years on university graduates with an average age of 42. "Over the course of the tracking and data collection stage, 190 smokers who initially did not present depression were diagnosed with this disease by a doctor. In addition, 65 who were not diagnosed indicated that they were taking antidepressants during this period,” indicated Miguel Ángel Martínez-González, director of the research project and Chair Professor of the Department of Preventive Medicine and Public Health.

Among the mechanisms that shed light on this relationship, he points to “genetic and/or environmental disposition, which will increase the probability that the tobacco habit is retained and that the user will suffer depression as an independent issue.”

Lessening of Physical Activity

In addition, the article indicates that those who had given up tobacco more than a decade previously have a lesser probability of developing depression than those who have never smoked.

The researchers also noted that an increase in tobacco use was correlated with a lessening of physical activity in the smoker’s free time.
