Objective: To analyze the level of the knowledge and related factors of cancer prevention and treatment among residents of Beijing in 2020. Methods: From April 14 to 21,a total of 11 721 residents were recruited in the study by using anonymous network sampling method. A WeChat online electronic questionnaires was conducted to collect basic demographic characteristics and the knowledge of cancer prevention and treatment. The Chi-square test was used to compare the difference of the level of the cancer prevention and treatment knowledge among different groups. A multivariate linear regression model was used to analyze the related factors. Results: Among the subjects, 72.9% (8 542) were male and 93.7% (10 983) were urban residents. The total number of questions answered by the subjects was 117 210 of which 89 093 were known, and the overall awareness rate among the residents was 76.0%. The female, aural residents, with junior college education, and worked in government institutions had a good performance of the knowledge (P<0.05), about 83.4%, 79.7%, 82.3% and 82.0% respectively. The results of multivariate linear regression model showed that female[β=0.798(95%CI:0.702,0.894)] and junior college education[β=3.271(95%CI:2.993,3.609)] could know more questions compared to male and primary school education (P<0.05); compared with working in the government institutions, agricultural laborer[β=-0.911(95%CI:-1.057,-0.766)], retired personnel[β=-2.273(95%CI:-2.532,-2.014)], school students[β=-0.629(95%CI:-0.796,-0.462)] and other occupation people[β=-0.376(95%CI:-0.634,-0.119)] could know fewer questions (P<0.05). Conclusion: The level of the cancer prevention and treatment knowledge among residents in Beijing was relatively high. Gender, education level and occupation were relevant factors.
目的： 分析2020年北京市居民癌症防治核心知识知晓水平及相关影响因素。 方法： 于2020年4月14—21日，采用网络方便抽样的方法，招募11 721名北京市常住居民为研究对象。利用微信公众号开展问卷调查，收集基本人口学特征、癌症防治核心知识等信息。采用χ²检验比较不同特征研究对象癌症防治核心知识知晓情况的差异，并采用多元线性回归模型分析居民癌症防治核心知识知晓情况的相关因素。 结果： 11 721名研究对象中，男性占72.9%（8 542名），城区占93.7%（10 983名）。应答条目数为117 210条，知晓条目数为89 093条，总体知晓率为76.0%。女性（83.4%）、郊区（79.7%）、大专/本科（82.3%）、机关事业单位工作者（82.0%）的知晓率较高（P值均<0.05）。多元线性回归模型分析结果显示，与男性、小学学历者相比，女性［β=0.798（95%CI：0.702，0.894）］、大专/本科［β=3.271（95%CI：2.993，3.609）］的知晓条目数较多（P值均<0.05）；与机关/事业单位工作者相比，农业劳动者［β=-0.911（95%CI：-1.057，-0.766）］、离退休［β=-2.273（95%CI：-2.532，-2.014）］、在校学生［β=-0.629（95%CI：-0.796，-0.462）］及其他职业人员［β=-0.376（95%CI：-0.634，-0.119）］的知晓条目数较少（P值均<0.05）。 结论： 北京市居民癌症防治核心知识知晓率较高，性别、文化程度和职业与知晓情况有关联。.
