Background:
Despite the well-documented relationship between weight gain and
poorer cessation outcomes among smokers, the role of the former (baseline) weight in
smoking cessation is insufficiently investigated. We hypothesized that patients with
higher baseline body mass index(BMI) have a worse prognosis in tobacco cessation.
Objectives:
This retrospective clinical cohort study aimed to investigate the role of the
baseline BMI on abstinence over 12 months after participation in smoking cessation
treatment conducted in a middle-income country (n = 664).
Methods:
Data from a 6-week smoking cessation protocol performed in a Psychosocial
Care Unit(CAPS) were used. The protocol included four medical consultations and six
Cognitive-Behavioral Therapy(CBT) group sessions. Initially, 1,213 participants were
evaluated for the study, but only the participants whose telephone contact was
successful were included in the outcome analyses. The attrition rate was 45.3%.
Continuous and categorical (normal, overweight, and obesity) BMI values were
computed. Survival regression models were used to test the associations between BMI
and the 12-month abstinence outcome. Self-report 4-week abstinence at the end of
treatment was also investigated using logistic regression models.
Results:
Baseline BMI had no significant effect on both short (4-week-point abstinence)
and long (12-month prolonged abstinence) treatment outcomes.
Conclusion:
The possible influence of the baseline BMI on smoking cessation
outcomes, especially considering prolonged abstinence, was not corroborated by our
results. Regardless of our results, the detrimental health outcomes due to the
combination of obesity/overweight and smoking justify that these subgroups of
individuals be continuously targeted for adequate smoking prevention and treatment.
