了解食管癌高发区农村居民对食管癌相关知识的认知现状，为食管癌预防及早诊早治提供依据。

采用自制问卷，于2017年7月4日至7月12日对食管癌高发区四川省盐亭县黄甸、富驿、两河3个乡镇农村居民的食管癌认知情况及影响认知情况的相关因素进行调查，并对调查结果进行统计学分析。

参与调查的3个乡镇农村居民共1 007人，有效问卷937份，有效率为93.0%。其中21～39、40～59、60～79、≥80岁者分别占22.3%、34.9%、38.8%和4.0%。居民的文化程度普遍较低，文化程度为小学及以下、初中者分别占47.9%和32.7%人。了解和清楚"知道食管癌、当地是高发区、食管癌诱因、主要症状、治疗措施、预防措施和政府的干预措施"的分别占21.2%、15.5%、12.8%、14.9%、8.4%、9.0%和7.9%。不同文化程度对是否知道食管癌、食管癌的诱因、治疗措施和预防措施方面的认知差异均有统计学意义(P<0.05)，有文化程度越高知晓率越高的趋势；对主要症状方面的认知差异无统计学意义(P>0.05)。非务农人群对食管癌和食管癌诱因方面的知晓率显著高于务农人群，差异有统计学意义(P<0.05)；但两组人群对主要症状、治疗措施和预防措施方面的认知差异无统计学意义(P>0.05)。不同年龄段居民对食管癌相关知识的认知差异无统计学意义(P>0.05)。

盐亭县农村居民对食管癌认知的总体水平仍较低，当地政府和疾控预防中心需加大宣传力度，以促进食管癌相关知识的普及，对高发区食管癌预防及早诊早治有重要意义。

To understand the prevalence of esophageal cancer-related knowledge of rural residents in high incidence area, and to provide evidence for the prevention, early diagnosis and treatment of esophageal cancer.

A self-made questionnaire was used to evaluate the cognitive status and influence of esophageal cancer among rural residents from 3 villages and towns which are high incidence areas of esophageal cancer in Huangdian, Fuyi and Lianghe of Sichuan province from July 4 to July 12.

A total of 1 007 rural residents participated in the survey. There were 937 valid questionnaires with an effective rate of 93.0%. Among them, 21 to 39, 40 to 59, 60 to 79 and 80 years old accounted for 22.3%, 34.9%, 38.8% and 4.0% respectively. Residents generally have a low level of education, with a minimum level of education and junior middle school education, accounting for 47.9% and 32.7% respectively. Residents who have heard of esophageal cancer, known that they live in high incidence area, and have the knowledge of incentives of the cancer, main symptoms, treatment measures, preventive measures and government intervention accounted for 21.2%, 15.5%, 12.8%, 14.9%, 8.4%, 9.0% and 7.9% respectively. There were significant differences in the cognitive abilities of esophageal cancer, treatment measures and preventive measures with different educational level (P <0.05), the higher the educational level, the higher the awareness rate. The awareness rate of non-agricultural population on the cause of esophageal cancer was significantly higher than that of farmers, and the difference was statistically significant (P<0.05). But there was no statistically significant difference between the two groups in terms of the main symptoms, treatment measures, and preventive measure (P>0.05). There were no statistically significant differences in the cognition of esophageal cancer in different age groups (P>0.05).

Yan Ting rural residents’ cognition on esophageal cancer overall is still low, and the local government and the Center for Disease Control and Prevention should intensify publicity and promote the esophageal cancer related knowledge, which can help to do prevention, early diagnosis and treatment of the cancer.
