Evolución del tabaquismo según clase social en la población adulta de las Islas Canarias durante el periodo 2000-2015: seguimiento de la cohorte CDC-Canarias

OBJECTIVE: To determine the status of tobacco consumption in the Canary Islands during 2000-2015, according to social class. LOCATION: Canary Islands. PARTICIPANTS: General population cohort, with contacts in 2000 (n = 6,729), 2008 (n = 6,171) and 2015 (n = 4,705). MAIN MEASUREMENTS: Smoking, gender, age, and social class. RESULTS: Consumption decreased by 6% (5-7%, P < .001) in general, being more accentuated in the period 2000-2008 (5%). The decrease was greater in men, although they continued to smoke more than women, with a prevalence of 25% (24-26%) compared to 18% (17-19%, P < .001). A decrease in consumption was only observed in the younger groups (6% [3-5%], P = .011) and intermediate ages (7% [6-8%], P < .001). A similar decrease was observed in all the social classes, but there was a higher prevalence of smoking in the upper class: 24% (23-25%) in 2015 (P < .001). By jointly assessing gender, age, and social class, younger and middle age men had the greatest decreases in consumption: 8% (7-9%) low and upper classes, 10% (9-11%) middle class. In the lower social class, younger women continue to smoke more (27%) although more of them quit smoking (14%), a phenomenon that occurred in the middle class at intermediate ages. CONCLUSIONS: The evolution of tobacco consumption in the Canary Islands follows a pattern similar to that of mainland Spain. The abandonment of tobacco consumption has slowed down in the period 2008-2015, especially in men, and middle and upper social classes.
