Background and objective: It has been proven that increase of the awareness level of lung cancer prevention and control could enhance participation of lung cancer screening of lung cancer high risk group. The aim of this study is to investigate the awareness level of lung cancer prevention and control and the effect of individual characteristics on lung cancer awareness, and to provide evidence for comprehensive lung cancer prevention in high risk areas of lung cancer.
Methods: Staffs of Tianjin Dagang Oil Field who participate low dose CT (LDCT) lung cancer screening by cluster sampling or according to voluntary principle were surveyed, data of lung cancer awareness were collected by questionnaire.
Results: A total of 1,633 valid questionnaires were collected. The average age of respondents was 60.08±6.58. Most participants were males (82.2%) while female only accounted for 17.8%. The proportions of awareness about lung cancer in China, risk factors, screening methods and the knowledge of health examination were 64.5%, 77.1%, 43.7%, 49.6% respectively. Result of multiple logistic regression analysis showed that education level, smoking (pack-year), age, prior tuberculosis were the influencing factors of lung cancer awareness with adjusted Ors for education and age level as of 0.567 (95%CI: 0.439-0.733) and 1.373 (95%CI: 1.084-1.739) respectively. 80.3% of the participants can accept health examination once a year, while the ability to pay the medical expenses was not high. The influencing factors of health examination willingness were gender, age, income, the knowledge of lung cancer.
Conclusions: Education level and smoking affect the awareness of lung cancer prevention and control, health education for lung cancer should be conducted especially in population with low education level. Comprehensive lung cancer control in high risk areas should combined lung cancer screening, tobacco control and health education.
背景与目的 已有的研究表明提高人群对肺癌防治知识的认识水平，有助于肺癌高危人群肺癌筛查项目的参与度。本研究的目的是调查卫生部肺癌早诊早治大港项目点低剂量螺旋（low dose CT, LDCT）肺癌筛查人群肺癌防治知识知晓情况及个体因素对其的影响，为肺癌高发现场的综合防治提供依据。方法 通过整群抽样和自愿参加方法对参加LDCT筛查的大港油田肺癌高发现场职工进行问卷调查。结果 本次调查共获得有效问卷1,633份，调查对象的平均年龄为60.08±6.58，男性1,343人（82.2%），女性290（17.8%）。对肺癌的知晓率、危险因素、筛查方法，体检意愿以及治疗的知晓率分别为：64.5%、77.1%、43.7%、49.6%、52.8%。多因素Logistic回归分析结果表明：教育、年龄、吸烟包年、疾病史是调查对象肺癌防治知识知晓的影响因素，教育和年龄的OR值分别为0.567（95%CI: 0.439-0.733）和1.373（95%CI: 1.084-1.739）。调查人群中80.3%的人群能接受1年1次的体检，人群体检费用承受能力不高。对被调查者体检意愿进行多因素分析得出，性别、年龄、癌症知识知晓情况以及家庭年平均收入是筛查意愿的影响因素。结论 教育程度和吸烟影响人群对肺癌防治知识的认知情况，应加强对低教育水平人群的癌症健康教育。在肺癌高发现场，肺癌的筛查应与戒烟和健康教育紧密结合，实行肺癌的综合防治。
