PMID 36449981WHAT IT FOUND
New tuberculosis cases among Indigenous villagers in Pará clustered in Belém and Marajó.
The spatial analysis found a direct relationship between TB incidence and Indigenous income-transfer beneficiary proportions.
Key findings
01The study identified 340 new TB cases among Indigenous villagers, with a crude incidence rate of 305.91 per 100,000 inhabitants.
02The highest crude TB incidence rates were in the Metropolitan mesoregion of Belém (837.61 cases/100 thousand inhabitants) and Marajó (454.55 cases/100 thousand inhabitants).
03The spatial analysis found a direct relationship between TB incidence and Indigenous income-transfer beneficiary proportions (I = 0.399, p = 0.027).

What it does not show
The study used publicly available notification and census data. The authors note possible underreporting, incomplete TB data in Indigenous peoples, and lack of income-transfer information in some municipalities. The authors suggest the 2020 decrease may reflect pandemic disruption of TB diagnosis and treatment. The unit of analysis was the mesoregion, not the individual patient.
The easy way to misread this
Do not read the association between income-transfer beneficiary proportions and TB incidence as evidence that cash benefits cause tuberculosis. The study is ecological and the authors note possible underreporting, incomplete data and missing income-transfer information.
