Abstract 15397: Smoking Cessation and Weight Gain in Patients With Cardiovascular Disease
There is a great correlation between stopping smoking and weight gain. Even though the benefit of quitting smoking overcome the impact of weight gain, understand and prevent this occurrence may encourage more people to quit smoking.
Objective: The aim of this study was to investigate variables which can impact on weighting gain in patients who quit smoking.
Material and Methods: A retrospective outcome research to evaluate weight in 887 patients submitted to smoking cessation program from 2008 to 2011 in a tertiary cardiovascular hospital. The treatment consists of an initial medical visit plus an average of 5 follow-up medical visits for 52 weeks. Patients received behavioral counseling and drug treatment from physicians specialized in smoking cessation. Continuous abstinence rate (CAR) was investigated after 52 weeks as of starting. Clinical data, weight, and carbon monoxide concentration were collected in all visits. Smoking status (outcome) was divided into: success group (patients who completed 52 weeks of CAR confirmed by carbon monoxide concentration), relapse group (patients who did not complete 52 weeks of CAR), and failure group (patients who never achieved CAR after starting treatment).
Results: The weight gain was higher in success group (5.5±6.1 Kg) compared to relapse (1.4±4.3 Kg) and failure (0.7±3.0 Kg) groups (p< 0.001). Those who had success in the treatment, 50.9% gained more than 5% weight, and 23.3% gained more than 10% weight. Demographic and clinical data, pharmacological strategy and Fagerstrom score were analyzed to predict weight gain in success group. The high level of Fagerstrom score (OR 1.23, p=0.01) and female gender (OR 2.43, p<0.01) showed to be significantly associated with weight gain in success group.
Conclusion: Even though the limitations of this study related to retrospective analyses, this found is very consist and suggest the necessity to develop best strategy to avoid weight gain in this population.
