Abstract: ObjectiveTo explore the factors related to new smear positive pulmonary tuberculosis with limited access to health care in Guizhou province. Methods11697 new smear positive pulmonary tuberculosis patients registered from 51 counties in Guizhou province were investigated by questionnaire and Logistic regression was used for data analysis. ResultsThe patient’s age, home address, fatigue, cough, night sweat, other symptoms, diagnostic medical institutions and lesions were included in the regression model for multi-factor analysis, with odds ratios and 95% CI 0.907(0.880～0.936)， 0.243(0.215～0.275)， 0.709(0.605～0.830)， 0.665(0.459～0.964)， 1.558(1.137～2.136)， 0.721(0.603～0.861)， 2.984(2.381～3.740) and 0.792(0.729～0.862) respectively. ConclusionsYoung and middle-aged patients, living in rural areas, neglected symptoms, diagnosis in non-TB control institution, double side lesions or cavities when diagnosed were important factors related to new smear positive pulmonary tuberculosis with limited access to health care.
