摘　　要：目的:了解2019、2021年四川省居民癌症防治核心知识知晓情况及其变化。方法:分别于2019年4~5月和2021年4~5月,采用方便抽样的方法,利用“四川省癌症防治中心”官方微信公众号发布匿名问卷开展调查,招募≥18岁四川省常住居民为研究对象,收集其癌症防治核心知识知晓情况。选取2021年调查对象为处理组,2019年调查对象为控制组,使用倾向性评分匹配法(propensity score matching,PSM)对两组调查对象基本情况进行匹配,并分析PSM匹配后四川省居民癌症防治核心知识知晓情况的变化。结果:经过PSM,2021年与2019年调查人群成功匹配20140对。实现两组调查对象在性别、年龄、职业以及所在经济区等特征上的分布达到均衡后,2021年四川省居民总体癌症防治核心知识知晓率(67.96%)高于2019年(63.02%),差异有统计学意义(χ^(2)=1085.564,P<0.001),但两次调查的总体知晓率差距由匹配前的5.09%下降至匹配后的4.94%。结论:与2019年相比,2021年四川省癌症防治核心知识知晓率有所提高。今后应系统地采取方法提高居民对专业性较强的癌防知识的知晓水平,进而提高四川省居民总体癌症防治核心知识知晓情况。Objective:To investigate the changes in the awareness of cancer prevention and treatment knowledge among Sichuan residents in 2019 and 2021.Methods:Two crosssectional surveys targeted the residents aged 18 years in Sichuan province were separately conducted(one was conducted from April to May 2021)using convenient sampling,and their knowledge on cancer prevention and treatment were investigated through an anonymous questionnaire from the official WeChat account of Sichuan Cancer Center.The 2021-year subjects were assigned to the processing group,while the 2019-year subjects to the control group.Propensity score matching(PSM)method was used to equalize the basic information of the respondents.After PSM,we analyzed the changes in awareness of cancer prevention and treatment knowledge among Sichuan residents over these two years.Results:Via PSM,a total of 20,140 pairs of respondents in the two surveys were successfully matched.After achieving a balanced distribution of the respondents in terms of gender,age,occupation and economic zone,the 2021-year respondents still had statistically higher overall awareness rate of cancer prevention and control knowledge than did the 2019-year respondents(67.96%vs 63.02%)(χ^(2)=1,085.564,P<0.001).However,the gap between the overall awareness rates in the two surveys decreased from 5.09%before PSM to 4.94%after PSM.Conclusion:Compared with 2019,the awareness rate of cancer prevention and treatment knowledge among Sichuan residents was improved in 2021.In the future,a systematic approach should be adopted to improve their professional cancer prevention and control knowledge,so as to improve the overall awareness rate among residents in Sichuan.
