Description

Background: Knowing which personal variables influence smoking relapse can help to improve cessation treatment effectiveness. Previous research has indicated that high body mass index (BMI) may be associated with smoking cessation treatment failure. However, scarce research has analyzed the relationship of this variable with long-term relapse outcomes. This study examines whether baseline BMI is related to relapse at 3-,6-, and 12-month follow-ups in a sample of individuals who initially achieved abstinence during a smoking cessation intervention.

Methods: The sample was 296 adults who were abstinent at the end of a cognitive-behavioral smoking cessation program (62.3% women; M_age = 45.12 years; SD = 11.31) at the Smoking Cessation and Addictive Disorders Unit of the University of Santiago de Compostela (Spain). Logistic regression analyses were conducted to examine whether the BMI, categorized into three groups: normal/underweight (<25), overweight (25–29.9), and obese (≥30), was associated with smoking relapse at 3, 6, and 12 months after the end of the smoking cessation intervention.

Results: Of the total sample, 49.66% were categorized in the normal/underweight group, 35.14% in the overweight group and 15.20% in the obese group. Data showed that participants in the overweight group were significantly more likely to relapse compared to those in the normal/underweight group at 3-(odds ratio [OR]= 2.34; p = .001), 6-(OR = 1.67; p = .046), and 12-month follow-ups (OR = 1.86; p = .018).

Discussion: Baseline overweight BMI was associated with an increased risk of relapse over the one-year follow-up period. These findings suggest that BMI should be considered when designing smoking cessation interventions. Future research exploring the interaction between BMI and psychological or behavioral factors is needed. This may help to design tailored interventions to prevent smoking relapses.
