[Logistic analysis on risk factors related to smear positive pulmonary tuberculosis].
OBJECTIVE
To explore the risk factors on relapsing tuberculosis related to smear positive pulmonary tuberculosis which had been cured for five years.


METHODS
Patients with smear positive pulmonary tuberculosis registered in 1995 from ten countries in Hubei province were studied and logistic regression was used for data analysis.


RESULTS
The 5-year relapse rate of smear positive pulmonary tuberculosis was 3.85 percent. Risk factors related to relapse would include being non-modeled county, negative smear after treated for three months, the class of retreatment, management of non-DOTS, method of chemotherapy and patients that did not get treated by the tuberculosis institute, with odds ratios of 0.15, 4.62, 3.68, 5.88 and 6.47, respectively.


CONCLUSIONS
Effect standard, regulation DOTS and the centralized management measure might have had effects on decreasing the relapse rate.
