Associations of Weight Concerns With Self-Efficacy and Motivation to Quit Smoking: A Population-Based Study Among Finnish Daily Smokers.
Nicotine Tob Res 2015 17: 1134-1141
Concerns about weight gain occurring after smoking cessation may affect motivation and self-efficacy towards quitting smoking. We examined associations of smoking-specific weight concerns with smoking cessation motivation and self-efficacy in a population-based cross-sectional sample of daily smokers. Six-hundred biochemically verified (blood cotinine) current daily smokers comprising 318 men and 282 women aged 25–74 years, were studied as part of the National FINRISK (Finnish Population Survey on Risk Factors on Chronic, Noncommunicable Diseases) study and its DIetary, Lifestyle and Genetic factors in the development of Obesity and Metabolic syndrome (DILGOM) sub-study that was conducted in Finland in 2007. Self-reported scales were used to assess weight concerns, motivation and self-efficacy regarding the cessation of smoking. Multiple regression analyses of concerns about weight in relation to motivation and self-efficacy were conducted with adjustments for sex, age (years), body mass index (BMI, [kg/m2]), physical activity (times per week), and further controlled for nicotine dependence (Fagerström Test for Nicotine Dependence).
Higher levels of weight concerns were associated with lower self-efficacy (β = −0.07, p < .001) after adjusting for sex and age. The association remained after additional adjustment for BMI and physical activity (β = −0.07, p < .001). After further controlling for nicotine dependence the association became weaker but remained significant (β = −0.04, p = .02). There were no statistically significant associations between concerns about weight and motivation for smoking cessation (β = 0.02, p = 0.16). These cross-sectional population-based data do not support earlier findings that suggest that smokers with high levels of weight concerns are less motivated to quit smoking. Our data suggest that daily smokers who are highly concerned about weight may have lower self-efficacy for cessation of smoking.
