Hypothesis
How will tuberculosis incidence change as countries undergo epidemiological transitions with increasing diabetes prevalence and changing BMI?
Conclusion
Nutritional and demographic changes had stronger adverse effects on tuberculosis in high-incidence India than in lower-incidence Korea.
Supporting Evidence
- In India, TB cases increased by 28% from 1998 to 2008 due to rising diabetes and changing BMI.
- In Korea, TB cases increased by only 6% during the same period, aided by stable diabetes prevalence.
- Urbanization in India raised TB incidence due to higher transmission rates in cities.
- The prevalence of diabetes in India rose from 3.0% to 3.7% between 1998 and 2008.
Takeaway
This study looks at how changes in diet and health affect tuberculosis rates in India and Korea. In India, more diabetes and changes in body weight are making TB worse, while Korea is seeing improvements.
Methodology
Data on BMI, diabetes prevalence, and population age structure were compiled and analyzed for India and Korea to calculate expected changes in TB incidence from 1998 to 2008.
Potential Biases
Potential biases due to differences in survey methods and data collection.
Limitations
Data quality varied between India and Korea, and the analysis was limited to these two countries.
Participant Demographics
Adult populations in India and Korea, with a focus on age, sex, and urban/rural living conditions.
