Study finds link between spike in cost of living and tuberculosis death rate

New U of T research finds that a rise in the cost of living experienced during times of crisis – like war, outbreaks of disease and food shortages – can lead to a spike in tuberculosis mortality rates, with women the most vulnerable.

"During times of great stress, women were at greater risk, and the likely reason is because of traditional gender roles," says Lianne Tripp, an assistant professor at University of Northern British Columbia and former PhD student in U of T Scarborough's department of anthropology.

Using 20th century economic and demographic data from Malta and the nearby island of Gozo, Tripp and former supervisor Professor Larry Sawchuk of U of T Scarborough found a noticeable relationship between a rise in the cost of living and increased rates in deaths from tuberculosis (TB).

The study, which is published in the journal PLOS ONE, also uncovered evidence of the harvesting effect that occurred following TB outbreaks when the mortality rates dropped to lower rates than normal.Sawchuk's past research explored the phenomenon, which occurs when those who are vulnerable, such as the sick, weak or elderly, die during a disease outbreak.
