[Blood pressure in 6 Yanomami villages].
OBJECTIVE
To investigate in Yanomami Indians that not add salt to food, the relationship between blood pressure (BP), biological variables (age, body weight, height and pulse) and urinary electrolytes (Na+, K+, Ca++ and Mg++).


METHODS
We studied 125 males and 129 females from six villages on Surucuru plateau and on Catrimani and Ajarani rivers region in the state of Roraima, north Brazil. Two BP measurements were made and the mean of them were used in data analysis.


RESULTS
None hypertensive was found. Systolic BP decreased with age and correlated with body weight, pulse and urinary Na+. Diastolic BP only correlated with body weight. Height, urinary K+, Ca++ and Mg++ did not correlate with BP.


CONCLUSIONS
There was no hypertension nor increase of BP with increasing age in these isolated Yanomami.
