The role of tuberculosis control institutes in delivering TB information to domestic migrants in China: a multi-level analysis of a nationwide cross-sectional survey

Abstract Objectives We aim to understand how TB control institutes raise awareness of TB to domestic migrants in China, specifically, if migrants have received TB information and how they received it. Methods This multi-level analysis included both county-level data and individual-level data covering 31 provinces in mainland China. We carried out multi-level logistic models to explore the associated factors of receiving TB information. Results Our analysis included 205,990 migrants from 31 provinces and municipalities. Only 77,460 (37.60%) migrants reportedly received any TB information in mainland China. The center for disease control and prevention (CDC), the center for tuberculosis control (CTC), and the center for prevention and treatment of chronic diseases (CPTCD) were the most likely to provide TB information for migrants in comparison to other types of TB control institutes such as general hospitals, specialized hospitals, and community healthcare centers. The odds ratios were calculated as: 1.563 (95% CI: 1.246, 1.959) for CDCs, 1.385 (95% CI: 1.063, 1.804) for CTCs, and 1.723 (95% CI: 1.424, 2.085) for CPTCDs. Conclusion China has not achieved universal coverage of TB awareness. TB awareness levels are higher in regions with CDC, CTC and CPTCD institutes. Domestic migrants that have moved to Western areas are more likely to have received TB information.
