High blood pressure levels and cardiovascular risk among Munduruku indigenous people.
Neuliane Melo Sombra, Hanna Lorena Moraes Gomes, António Manuel Sousa and 3 others
PMID 34495189WHAT IT FOUND
Among 459 Munduruku indigenous adults, 10.2% had hypertension and 4.1% had pre-hypertension.
Older age, larger waist, diabetes, smoking, and inactivity were linked to hypertension.
Key findings
01Among 459 Munduruku indigenous adults, 10.2% were classified as hypertensive and 4.1% as pre-hypertensive.
02In the final model, substantially increased waist was reported as 7 times more likely for pre-hypertension and 5 times more likely for hypertension.
03Active or very active participants were reported as less likely to have hypertension than sedentary participants, while alcohol consumption was not reported as associated with pre-hypertension or hypertension.

What it does not show
This was a cross-sectional survey, so it can show associations but cannot prove that any factor caused high blood pressure. The pre-hypertension group was small, so estimates for that outcome are less stable. Hypertension was classified by measurement, self-reported diagnosis, or medication use, which may mix different sources of information. Anthropometric cutoffs were national rather than specific to indigenous populations. Several metabolic and lifestyle variables were correlated, and the final model selected among them, so independent effects are uncertain. Participants were from Munduruku villages in Amazonas, so results may not apply to other indigenous groups or settings. Pregnant people and those unable to complete examinations were excluded.
The easy way to misread this
Do not conclude that reducing waist size or increasing activity will lower blood pressure. This was a cross-sectional survey, and the final model selected among many correlated variables.
