Abstract
Few studies have simultaneously considered the effects of significant others and medical professionals’ advice to quit smoking on smoking cessation intention. The present study involved 3841 current adult Korean smokers, divided into four groups with an intention to quit within 1 month, within 6 months, someday, and without intention to quit. Multinomial multiple logistic regression analysis was conducted according to smoking cessation intention level, adjusted for potential confounders, including past smoking cessation attempts. Smokers who had been advised to quit smoking by both significant others and medical professionals, significant others only, and medical professionals only were 2.63 (95% confidence interval (CI): 1.62–4.29), 1.84 (95% CI: 1.17–2.89), and 1.44 (95% CI: 0.70–2.94) times more likely to intend to quit within 1 month, respectively, than those who were not advised to quit. The odds ratios of an intention to quit within 6 months were 2.91 (95% CI: 1.87–4.54), 2.49 (95% CI: 1.69–3.68), and 0.94 (95% CI: 0.44–2.05), respectively. To promote smokers’ intention to quit, the role of significant others should be considered. Medical professionals’ advice to quit smoking remains important, increasing the effects of significant others’ advice.
Highlights
Few studies have simultaneously considered the effects of significant others and medical professionals’ advice to quit smoking on smoking cessation intention
The rate of the intention to quit within 1 month was the highest among those participants who got advice from medical professionals only (7.7%), followed by medical professionals and significant others (7.0%), significant others only (4.6%), and no one (4.2%)
There were significant differences in the rates of intention to quit smoking within 1 month according to smoking frequency/amount, exposure to public anti-smoking campaigns within the past year, and experience of smoking cessation within the past year (Table 1)
Summary
Few studies have simultaneously considered the effects of significant others and medical professionals’ advice to quit smoking on smoking cessation intention. In 2015, worldwide, the age-standardized prevalence of daily smoking was 25.0% for men and. This evidence suggests that programs aimed at the prevention and cessation of tobacco consumption should be among the top priorities of national public health policies. According to the stages of change, a core construct of the transtheoretical model, smoking cessation involves a progression through precontemplation, contemplation, preparation, action, maintenance, and termination [2]. These stages tend to present as three distinct states: intention to quit, an attempt to quit, and successful quitting [3]. According to the theory of planed behavior, the most important direct determinant of behavior is behavioral intention [4]
