[Smoking habit among workers of the public health system in Tenerife]. / Hábito tabaáquico en los trabajadores del sistema sanitario público de Tenerife.

OBJECTIVE: To find the prevalence of tobacco use among workers in the Public Health system and to assess their own attitudes to the possibility of giving up smoking. DESIGN: A descriptive study of a crossover type was carried out using a self-filled closed-answer questionnaire. SETTING: The Public Health system on the island of Tenerife. PARTICIPANTS: After stratified random sampling, a sample of 1,282 workers was obtained, of whom 770 (60%) answered the questionnaire. Later a reply was obtained from 10% of those who did not at first reply, without any differences from the other participants being apparent. MEASUREMENTS AND MAIN RESULTS: Overall prevalence is 43% of smokers, 13% ex-smokers and 44% non-smokers. 20% of the smokers have an important physical dependency and only 30.76% are highly motivated to stop smoking. 56% of smokers feel home pressure to stop smoking, while only 29.5% of smokers feel pressured at work. We elaborated a scale, which was useful in measuring peoples' motivation to abandon the habit. CONCLUSIONS: Almost half these workers are smokers at present. Despite belonging to the Health system, they are no more motivated than the general population they look after.
