Hypothesis

To determine the role of the migrant population in the transmission of tuberculosis (TB).

Conclusion

The study found that migrants have a significantly higher risk of TB compared to permanent residents in Beijing.

Supporting Evidence

  • The migrant population accounted for 80% of TB cases among permanent residents in 2006.
  • The study analyzed TB cases from 2000 to 2006 in Beijing.
  • Hot spots of TB were identified in central districts with high migrant populations.

Takeaway

This study shows that people who move to Beijing from other parts of China are getting sick with tuberculosis more than those who live there permanently.

Methodology

Exploratory spatial data analysis and GIS-based multilevel extra Poisson regression models were used to analyze TB cases.

Potential Biases

Individual differences may have been missed when aggregating data to the district level.

Limitations

The study was retrospective and could not assess the impact of businesspersons and travelers on TB transmission.

Participant Demographics

61.6% of the migrant population were male; migrants came from various zones in China.
