| [Purpose] To analyze the compliance and its influencing factors of low-dose computed tomography (LDCT) screening among high-risk population of lung cancer in urban Beijing during 2014 to 2019, and to provide evidence for optimizing cancer prevention and control strategies. [Methods] We recruited permanent residents aged 40 – 69 years from community sites of Beijing Cancer Early Diagnosis and Treatment Project in six urban districts (Dongcheng, Xicheng, Chaoyang, Haidian, Fengtai and Shijingshan) of Beijing by cluster sampling method, and conducted questionnaire survey to assess their risk of cancer. The residents assessed as at high-risk of lung cancer were advised to have LDCT screening in designated hospitals. Chi-square tests were adopted to compare the differences in participation rate (compliance) of the LDCT screening among various groups and the multivariate unconditional logistic regression model was used to explore potential factors related to the compliance of LDCT screening. [Results] Among 88 044 residents who completed the questionnaire, 20 371 cases (23.1%) were evaluated as a high-risk individual of lung cancer. 10 645 subjects received LDCT screening, with an overall participation rate of 52.3%. The multivariate analysis showed that female, people aged over 50 years old, with university/college degree or above, history of harmful occupational exposure, much kitchen fumes when cooking at home, passive smokers, self-reported trauma or depression were more likely to take part in endoscopic screening while current smokers got poorer compliance (P<0.05 for all above). [Conclusion] There is still room for improvement in compliance of LDCT screening among high-risk population of lung cancer in urban Beijing. Precise health education and management strategies should be implemented in high-risk population with different characteristics to further improve the compliance in the future. |
