Analysis Of Detection Rate And Related Factors Of Lung Nodules In Healthy People

Objective To understand the prevalence of pulmonary nodules in urban health checkups,and to analyze the related factors of pulmonary nodules to explore the rational applicati-on of low-dose spiral CT in the chest in patients with pulmonary nodules.Methods Retrospective analysis During the period from January to May 2018,8277 people who underwent a physical examination at the Dalian Central Hospital Medical Center and improved the CT scan of the chest were included in the study,including4,362 males and 3,919 females.Using single factor correlation analysis and multivariate logistic regression to analyze the detection rate of lung nodules in healthy people,combined with relevant factors for analysis.Results In 8281 patients with complete lung CT examination,the detection rate of pulmonary nodules was 18.3%,of which the male detection rate was 15.9% and the female detection rate was 20.9%.For the longitudinal analysis of all age groups,the female detection rate was higher than that of males,and the detection rate of females in the age group of 40-50,50-60,60-70 was significantly higher than that of males,and the difference was statistically significant(P <0.05),with the increase of age,the detection rate of lung nodules increased(P<0.05).Multivariate logistic regression analysis showed that age,gender,smoking history,drinking history,past tumor history and tumor family history were correlated with lung nodule detection rate,and BMI was not correlated with lung nodule detection rate.Conclusion There was a significant negative correlation between gender and lung nodule detection rate(P<0.05),that is,women were more likely to detect lung nodules than men;age,smoking history,drinking history,past tumor history,and family history of cancer 6 There was a significant positive correlation between the index and the detection rate of pulmonary nodules(P<0.05),and it was an independent risk factor(OR>1)affecting the detection rate of pulmonary nodules,that is,the older the age,the history of drinking,People with a history of smoking,a history of cancer,and a family history of cancer are more likely to detect pulmonary nodules.Logistic regression results basically support the results of single factor correlation analysis.The detection rate of the population above 45 years old was 20.1%,which was significantly higher than that of the population below 45 years old(P<0.05).Conclusion In the health examination,it is recommended that people aged 40-70 years undergo CT scans of the chest,especially women,those with a history of cancer,a family history of cancer,a history of smoking,and a history of drinking.
