[Profile of smokers who seek treatment at a smoking cessation clinic].

OBJECTIVES

The variety of smoking cessation therapies that have proven effective ranges from simple counseling to intensive interventions. The objective of our study was to identify the characteristics of smokers who currently seek treatment at a smoking cessation clinic.

METHODS

Descriptive observational study. The target population consisted of smokers who sought treatment at a smoking cessation clinic. The following variables were studied: sex; age; referral source; marital status; educational level; age at which smoking began, age at which it became a regular habit and the time elapsed between the two moments; level of nicotine dependence (Fagerström Test for Nicotine Dependence); number of cigarettes per day; number of years smoking; use of other potentially-addictive substances (alcohol, caffeine, psychotropic medications and other drugs); presence of concomitant disease; previous attempts to quit smoking; current reasons for smoking cessation; and concentration of expired air carbon monoxide (CO). An initial medical history was taken from each smoker on the waiting list for treatment at the clinic in order to gather data on the study variables; these individuals were then enrolled in a 3-month group smoking cessation program that utilized both medication and cognitive-behavioral therapy. The results are presented in percentages and means with standard deviations (SD) and 95% confidence intervals (CI).

RESULTS

385 smokers were studied--239 (62%) men and 146 (38%) women--the average age being 43.05 years (SD: 9.07). Mean nicotine-dependence (Fagerström Test score) was 6.05 (SD: 2.19); mean number of cigarettes per day: 25.9 (SD: 12.11); mean number of years as a smoker: 25.3 (SD: 9.04); and mean expired air CO: 39.30 (SD: 25.18). Associated disease was present as chronic bronchitis for 27.5% and cardiovascular risk factors for 15%. Previous attempts to quit smoking were reported by 72%; the reasons for the present attempt to quit smoking were the prevention of disease (38%), awareness of dependence (20%) and parental desire to serve as a positive role model for children (10%).

CONCLUSIONS

At present, the smokers who attend a smoking cessation clinic are young, severely-dependent adults in the initial stage of preparing to quit. The prevalence of symptoms in this population is low. The profile of the population seeking specialized smoking cessation treatment is expected to change in the future as those with smoking-related diseases and other specific populations of smokers become included.
