Abstract: Background　Chronic disease prevention and control is still the primary health proposition in modern society. So it is urgent to improve the ability of chronic disease prevention and control in community medical workers. Evidence-based chronic disease prevention and control，a means for improving relevant abilities of medical workers，has achieved notable results in western countries，but has been rarely studied in China. Objective　To explore the ways and ability for obtaining chronic disease prevention and control evidence and associated factors in community medial workers，offering a theoretical basis for improving the related abilities in such workers. Methods　Using stratified sampling，a self-administered questionnaire survey was conducted in 975 medical workers in 75 community health centers from April to July 2019，for collecting the data about their socio-demographic information，awareness of evidence-based medicine，and ways and ability to obtain evidence for chronic disease prevention and control（with items scored on a self-rated 7-point Likert scale）. Stepwise multiple linear regression analysis was applied to identity the influencing factors of ability for obtaining the evidence. Results　A total of 892（91.5%） community medical workers returned responsive questionnaires. The results showed that clinical guidelines are the most common way for obtaining chronic disease prevention and control evidence，scoring（4.583±1.177） on average. The average self-rated score for the accuracy and effectiveness of obtained chronic disease prevention and control evidence was（4.312±0.979）. The average self-rated scores for obtaining and using the evidence about risk factors for chronic diseases were（4.244±1.028） （4.280±0.995），respectively. Stepwise multiple linear regression analysis revealed that working at a community healthcare institution affiliated to a university was associated with the obtaining and use of chronic disease prevention and control evidence as well as the accuracy and effectiveness of the evidence（P<0.05）. Conclusion　Working at a community healthcare institution affiliated to a university may be the foremost factor associated with the ability of obtaining chronic disease prevention and control evidence in community medical workers. So the ways for obtaining the evidence in this group should be attached importance，and their abilities of obtaining and using the evidence should be improved by training.
