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

• A nationwide, representative survey with a large sample size was performed in China. • Low coverage of tuberculosis (TB) awareness among rural-to-urban migrants in China was observed. • The study provides new insight into the role of TB control institutes in delivering TB information. • TB awareness levels are higher in regions with public health system. The aim of this study was to understand how tuberculosis (TB) control institutes raise awareness of TB among domestic migrants in China, specifically whether migrants have received TB information and how they received it. This multi-level analysis included both county-level data and individual-level data covering 31 provinces in mainland China. Multi-level logistic models were used to explore the factors associated with receiving TB information. This 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% confidence interval (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. China has not achieved universal coverage of TB awareness. TB awareness levels are higher in regions with CDC, CTC, and CPTCD institutes. Domestic migrants who have moved to western areas are more likely to have received TB information. [ABSTRACT FROM AUTHOR]
