To investigate smoking cessation behaviors and factors influencing it among adult community smokers in Beijing.

This was a cross-sectional epidemiological study. A questionnaire survey was administered among community smokers over 18 years old, in which information on basic demographics, tobacco use, attempts to quit smoking, tobacco-related awareness, and environmental assessment of smoking cessation support were collected. Descriptive analysis was conducted on the basic information, smoking situation, and demand for smoking cessation intervention of the respondents. Two tests were used to examine the quitting attempts of respondents. Tobacco attempts was found to be correlated with socio-demographic indicators, and factors such as tobacco use, awareness of tobacco-related issues, and the smoking cessation support environment. Dual logistic regression was used to further explore the dependence of identified factors and attempted smoking cessation behavior.

A total of 449 respondents were enrolled in this study, 410 of them were men (91.3%). Among the respondents, 272 people (60.6%) had tried to quit smoking and 177 people (39.4%) did not try to quit smoking. Monthly income level, tobacco-related awareness, degree of surrounding people supporting smoking cessation, whether medical treatment was sought in the previous year, number of visits, whether to persuade medical staff to quit smoking in the past year, and whether smoking was given up in the past year were the identified factors. These seven factors, such as whether they have been asked about smoking, are the influencing factors in trying to quit smoking（P<0.05）. Under the logistic regression model, monthly income level (OR=1.271, 95%CI:1.081-1.493), the support of people around them to quit smoking (OR=1.251, 95%CI:1.035-1.512), and the suggestion of medical personnel in the past year (OR=2.382, 95%CI: 1.054-5.381) were found to encourage attempts to quit smoking.

Factors such as health status, environmental support, hazard perception, and economic level influence attempts to quit smoking. Lack of self-determination and other people's influence are the main reasons for failing to quit smoking. Taking community places as the basic unit of intervention combined with professional guidance of smoking cessation clinic doctors and forming an online comprehensive linkage smoking cessation hospital community intervention model is an innovative way to optimize the management of tobacco dependence.
