WHAT IS A HEALTH DISPARITY?

“The difference in the

incidence, prevalence,

mortality, and burden of

disease and other adverse

health conditions that exist

among specific population

groups in the United States.”

(National Institutes of Health)

TB DISPARITY IN ASIANS


11 Boston Public Health Commission

IMMIGRATION

• Immigration is a social

determinant of health

• Issues with the immigration

process

• Key issues at destination:

• Overcrowded working and

living conditions

• Language and cultural

barriers

• Lack of healthcare access

GENETIC FACTORS

• IL-18 gene o Activates macrophages - helps kill MTB

o Polymorphisms alter IL-18 expression via binding of transcription factors

• P2X7 receptor gene 1513 A→C polymorphism o P2X7 receptor - induced by ATP to engulf and clear MTB in macrophages

o 1513 A→C SNP reduces P2X7 function

WAYS TO COUNTER TB HEALTH DISPARITIES

1. Facilitate patient awareness and education for prevention,

diagnosis, and treatment of tuberculosis

2. Create or modify local, low-cost TB screening programs in at-

risk cities

3. Improve screening processes during immigration

4. Embrace diverse cultures and provide support services

16

CONCLUSION

• Highest number of TB cases in MA found in Asians (44%)

• Boston has about 5 times as many cases as other major cities

• Foreign-born cases make up 80-90% of all TB cases in Boston

• Immigration plays an important role in TB disparity

• Potential genetic factors affect TB susceptibility in Asians

• Plan to reduce TB Health Disparities
