Abstract:
[Purpose]To analyze the compliance and its influencing factors of lung cancer screening using low-dose computed tomography(LDCT)among high-risk population in urban districts of Chongqing from 2013 to 2021.[Methods]The lung cancer screeing of Cancer Early Diagnosis and Treatment Project was conducted among permanent residents aged 40～69 years old from 14 urban districts of Chongqing selected by cluster sampling method from 2013 to 2021.The questionnaire survey was performed to assess the risk level of lung cancer,and individuals with high risk were advised to have LDCT examination.The compliance rate of LDCT examination among high-risk populations was calculated and compared using Chi-square test among residents with different de-mographic features;the influencing factors of compliance was analyzed with generalized linear mixed models.[Results]A total of 316 066 residents completed the risk assessment questionnaire survey,52 858 people were assessed as high-risk(17.17％).Among the high-risk population,20 398 completed LDCT screening,with an overall compliance rate of 38.59％.The generalized linear mixed model showed that male participants(OR=0.871,95％CI:0.823～0.922)and smokers(light smokers:OR=0.829,95％CI:0.775～0.886;heavy smokers:OR=0.842,95％CI:0.792～0.896)had lower compliance rates;while people with higher education level(OR=1.347,95％CI:1.265～1.435),occupational exposure to harmful substances(OR=1.400,95％CI:1.340～1.463),passive smoking for 20 years or more(OR=1.472,95％CI:1.376～1.576),infrequent physical exercise(OR=1.203,95％CI:1.152～1.256),family history of lung cancer(OR=2.312,95％CI:2.201～2.429),and those having media promotion by community staff(OR=1.365,95％CI:1.223～1.524),and trained community staff(OR=1.343,95％CI:1.227～1.470)had higher compliance rates.Comorbidities were also factors influencing compliance,and there was an increasing trend of compliance rate with the increase of comorbidity numbers(P＜0.001).[Conclusion]The compli-ance rate of LDCT examination for lung cancer screening in Chongqing needs to be improved,and more precise health education should be implemented for groups with different characteristics to improve the compliance among high-risk population.
