Objective: To explore the impact of family income on health-seeking, diagnosis and treatment delays for newly smear positive tuberculosis patients. Methods: There were 192 participants from 3 counties in Zhenjiang, which were selected by stratified random sampling method. A questionnaires survey was carried out in this study. Results: The mean of health-seeking, diagnosis and treatment delays was 15.92, 13.97 and 1.27 days, respectively. The mean of family per-capita income was 14 983.26 Yuan. There were no statistically significant differences in unacceptable health-seeking delay among different family income groups (P=0.128). However, a statistically significant difference was found in the level of medical institution initially visited among patients with different family per-capita income and there were a statistically significant differences in unacceptable diagnosis delay among different medical institutions (P < 0.001). Conclusion: Family income was not the main reason of health-seeking and treatment delays for newly smear positive tuberculosis patients in Zhenjiang. However, family income still had effect on diagnosis delay by choosing different medical institution initially visited.
