Objective: To investigate the attitude and behaviors towards tobacco control among civil servants in smoke-free governments of Ningbo City, so as to provide insights into the construction of smoke-free governments. Methods: Ten governments were randomly sampled from city-level and county/district-level smoke-free governments in Ningbo City using a stratified random sampling method, and 10 civil servants were sampled from each government using a convenient sampling method. Participants' demographics, attitude and behaviors towards tobacco control and second-hand smoke exposure were collected using a self-designed questionnaire and descriptively analyzed. Results: A total of 1 100 civil servants were recruited, including 466 men (42.36%) and had a mean age of (39.02±9.38) years. There were 1 005 participants favoring “civil servants should refuse smoking firstly” (91.36%), 1 058 participants favoring “governments should build a smoke-free environment firstly” (96.18%), 1 075 participants favoring “smoking should be completely banned in any indoor public places” (97.73%), 913 participants thinking that smoking should be completely banned in any indoor public places (83.00%) and 813 participants thinking that tobacco control regulations are implemented satisfactorily in their workplaces (73.91%). The overall prevalence of current smoking was 11.91% among participants, and the prevalence of current smoking was 28.11% among male participants. Among all current smokers, 84 attempted to quit smoking (64.12%), and 89 had willingness or plans to quit smoking (67.94%). The proportion of second-hand smoke exposure in workplaces was 40.97% among non-smokers in the past one week. Conclusions The civil servants in Ningbo City has correct awareness of smoke-free governments, active attitudes towards tobacco control and low prevalence of smoking.
