ABSTRACT

Objective To understand the intention to quit smoking and its influencing factors among current smokers in Gansu Province, so as to provide scientific basis for tobacco control. Methods A multi-stage sampling method was used to extract current smokers aged 15-69 years, and a face-to-face survey was conducted using the questionnaire on smoking among residents in China. Intention to quit smoking between current smokers with different characteristics was analyzed. Logistic regression was used to explore influencing factors of intention to quit smoking. Results The intention of current smokers to quit smoking in Gansu Province was 16.4% (95% CI15.5%-17.3%). Multivariate logistic regression analysis showed that current smokers who were in rural areas (OR=1.199, 95% CI1.022-1.408, P=0.026); family smoking prohibited (OR=1.767, 95% CI 1.273-2.454, P=0.001), medical staff discouraged smoking within 12 months (OR=1.599, 95% CI1.359-1.842, P<0.001), visited smoking clinics (OR=3.089, 95% CI2.031-4.698, P＜001), higher educational level of junior high school, senior high school and college or above (OR=1.383, 95% CI1.101-1.736; OR=1.627, 95% CI1.252-2.116; OR=1.374, 95% CI1.009-1.873, all P<0.05), tobacco hazards knowledge with higher scores of 1-, 3- and 5-6 (OR=1.248, 95% CI1.030-1.514; OR=1.574, 95% CI1.289-1.922; OR=2.288, 95% CI1.879-2.786, all P<0.05) were more likely to quit smoking; furthermore, smokers aged 20-, 30- years or smoking 20-, 30- years had a lower chance of quit smoking (all P<0.05). Conclusions The intention of current smokers to quit smoking in Gansu province is generally not high. In the future, knowledge of tobacco hazards should be further promoted, medical staff should provide more smoking cessation services during the treatment process, and more smoking cessation clinics should be established.
