Tuberculosis is one of the world’s most pervasive and deadly communicable disease with more than 10 million new cases and about 1.5 million deaths every year. Approximately one-third of the world’s population has latent tuberculosis infection, which means they carry the disease but do not have symptoms and cannot transmit it to others. Of those, 10% will develop active tuberculosis in their lifetime.

This month (July 2019), results from a study assessing the association between latent tuberculosis and vitamin D status were published. This study used 6,083 participants from the National Health and Nutrition Examination Survey (NHANES), which collects health information from a representative sample of individuals living in the United States.

What were the findings of the study?

The researchers found that those with latent tuberculosis had a lower average vitamin D level than those without the disease (25 vs. 28 ng/ml, P=0.0012). Those with the lowest vitamin D levels (less than 12 ng/ml) had more than two times the risk compared to those with the highest vitamin D levels (30 ng/ml or higher) (P=0.0009).

This association was adjusted for other risk factors such as gender, age, race, poverty, education, birthplace (US or foreign), BMI, diabetes, and high cholesterol.
