Study on the willingness to quit smoking and its influencing factors in adult smokers in China

Objective To explore the influencing factors of willingness to quit smoking in smokers,and to provide the reference for tobacco control. Methods The data were from 2015 National Adult Tobacco Using Survey in China. A multi-stage stratified cluster sampling method was used to select 15 094 residents (≥15 years old) from 16 800 households,among the residents,4 276 current smokers served as the subjects. The investigation was performed with the questionnaire(including general demographic characteristics,smoking status,and willingness to quit smoking). The statistical inference of 95% CI after weighting of complex sampling was used for single factor analysis,and the logistic regression analysis of complex sampling was used for multifactor analysis. The used software was SPSS 19.0. Results The proportion of adult smokers considering to quit smoking in the next 12 months in China was 17.6%. The proportion of willing quitters among those who smoke less than 1 pack a day was higher significantly than that among those who smoke ≥ 1 pack a day;the proportion of willing quitters among those who live in no allowed smoking family was higher significantly than that among those who live in allowed smoking family;the proportion of willing quitters among smokers who are aware that smoking can induce the stroke,heart disease and sexual dysfunction was higher significantly than that among smokers who are unaware(P<0.05). Multivariate logistic regression analysis found that the willing quit possibility in the smokers with smoking ≥1 pack a day(OR=1.509,95%CI:1.067-2.134),family allowing smoking(OR=1.682,95%CI:1.181-2.396),and unknowing the smoke resulting in sexual dysfunction(OR=1.522,95%CI:1.054-2.197) was significantly lower(P<0.05 or P<0.01). Conclusion It is suggested that health education should be provided to smokers through the establishment of a comprehensive smoke-free environment and the use of more efficient health communication methods. It is necessary to promote the comprehensive brief smoking cessation interventions in medical institutions to increase the willingness to quit smoking of smokers.
