[Implementation of Beijing Tobacco Control Regulation in restaurants in Dongcheng and Chaoyang districts of Beijing, 2018].

Objective: To evaluate the implementation effect of the Beijing Tobacco Control Regulation. Methods: An observational study was conducted in a multi-stage randomly selected sample of 93 restaurants in Dongcheng and Chaoyang districts, Beijing. Undercover visits to the restaurants were paid by investigators at lunch or dinner time. The incidence of smoking behavior and the posters of no-smoking signs were observed, waiters were interviewed about awareness of the regulation, and comparisons with the baseline data of 6 months before and 1 month after regulation implementation were made. Results: The pasting rate of no-smoking signs was 76.3 % . The awareness of the regulation in the waiters surveyed was high. The incidence rate of smoking in restaurants (29.0 % ) was lower than that before the regulation implementation (36.7 % ), but it was significantly higher than that one month after regulation implementation (14.8 % ). No active interventions from the restaurant staff were observed when smoking occurred. The incidence of smoking in restaurants within commercial buildings (3.3 % ) was significantly lower than that in non-commercial buildings (41.3 % ), the difference was significant ( P <0.05). Conclusions: The effect of the regulation weakened 3 years after implementation compared with that in 1 month after the implementation. The enforcement degree of the regulation was conflicted with pasting rate of no-smoking signs and the regulation awareness level in waiters in restaurants in Dongcheng and Chaoyang districts.
