Abstract:Objective To explore effective measures for creating a smoke-free environment at home. Methods A multi-stage cluster sampling method was used to sample households from two communities in Tianjin in 2014. With joint efforts of the communities’ neighborhood committees, schools and community healthcare service institutions, interventions including mass media publicity, booklets, theme exhibitions, tobacco control lectures, tabacco harm knowledge contest, micro-blog forwarding, smoke-free family declaration and other propaganda activities were conducted. Tobacco use among the family members aged over 15 years and indoor smoking of all familiy members and visitors in the last week were surveyed before and after the interventions. Results A total of 976 residents , including 468 males and 508 females, were investigated, with the total smoking rate of 21.3%. The smoking rates of males and females were 41.0% and 3.1% respectively. After the interventions, the total smoking rate decreased by 0.4%, but without a statistically significant difference (P=0.87). The proportion of residents having no desire to quit smoking decreased from 74.3% to 58.3%, with a statistically significant difference (P=0.000). The proportion of family members’ and guests’ smoking behavior at home, of residents using cigarettes to treat guests and of residents sending cigarettes as gifts to others declined by 19.6%, 32.5% and 63.0% respectively, with statistically significant differences (P=0.000). The awareness rates of health hazard of smoking and secondhand smoke were both increased significantly. The setting of smoke-free environment in the family was greatly improved, and the proportions of residents placing cigarettes and ashtray at home were decreased from 62.1% and 58.1% to 37.9% and 41.9% respectively. The proportions of households having butt (34.7% vs. 65.3%) and a smell of smoke (35.4% vs. 64.6%) were both significantly decreased. Conclusions With the cooperation of communities’ neighborhood committees, schools and community healthcare services institutions, implementing simple tobacco control interventions in families can obtain a good effect on tobacco control.
