[Evolution of Smoking According to Social Class in the Adult Population of the Canary Islands During 2000-2015: Follow-up of the CDC-Canary Cohort].

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.
