Abstract: Objective　The study was conducted to evaluate the effect of tobacco control among the staffs and the tobacco control environment in the center for disease control (CDC) system in Beijing, provide the basis for the extension of tobacco control in CDC system. Methods　Questionnaire surveys were conducted among the staffs of Beijing CDC system and a three-day on-site inspection of indoor and outdoor smoking for each CDC was performed to evaluate the performance of tobacco control strategies. Results　The smoking rate among CDC staffs was 21.6% with 45.2% for men and 5.2% for women. The smoking rate increased with age regardless of the gender. The passive smoking rate was 49.0%. Awareness of the hazards of smoking was relatively high (77.1%-98.9%). Different proportions of nonsmokers and smokers were observed on the acceptance of complete tobacco control in CDC (87.6% and 51.2% respectively). Complete tobacco control was implemented in 12 CDCs in Beijing and partial control in 6 CDCs, whereas no tobacco control was carried out in 2 CDCs. Generally, smoking was common in these centers with 62.5% of smoking happened in the non-smoking area, and only 30% of these smoking were dissuaded. Conclusion　Some progress had been made on the tobacco control in Beijing CDC system, but there are still plenty to do on the tobacco control, particularly on the education for smokers, strategy development and its effective implementation.
