A total of 26,246 respondents were interviewed using unified questionnaires that measured knowledge, attitudes, and behaviors regarding TB. The changes in public attitudes and behaviors towards TB over time were analyzed. The effect of socio-demographic factors and the level of TB awareness on TB discriminatory attitudes and isolated behaviors were evaluated.Results: The results of these four cross-sectional studies found that TB discrimination had not changed much over the decade. Overall, discriminatory attitudes were present in 63.5% of the respondents who knew about TB (81.2%). Nearly 31.2% of those who reported being surrounded by people with TB (5.8%) showed isolated behaviors. Older respondents, those with a low education level, and farmers were prone to having discriminatory attitudes or behaviors. Those aware of the infectiousness and transmission routes of TB, and those who felt that TB was serious were more likely to discriminate against TB (P < 0.001). Those aware that TB can be cured were non-discriminatory (aOR = 0.77, 95% CI: 0.72– 0.82).Conclusion: Discriminatory attitudes and isolated behaviors toward TB have not changed significantly in southeastern China over the survey years, and persistent discrimination against TB still exists among the public. The multiple causes of discrimination cannot be addressed through basic health education. Tailor-made strategies, relevant policy measures, and an enabling social environment for TB are urgently required.Keywords: tuberculosis, discrimination, attitude, behavior
