[Blood pressure in a Xavante tribe. Comparison after 15 years].

PURPOSE: To evaluate arterial blood pressure (BP), variations that occur with age, influence of new habits, in indians of a Xavante tribe, located in the state of Mato Grosso, Brazil. METHODS: The evaluation procedures took place in 9/75 and 10/90. Fifty Xavante were examined in 1975. Thirty-five of them were men and 15 women. The mean age of the men was 45 and of the women, 31. In 1990, only 46 of those indians were re-examined (two were not located and two had already died of cancer and pneumonia), and evaluated with regard to arterial BP, food ingestion, physical activities, obesity, tobacco, alcoholic beverage consumption and social organization. RESULTS: In both occasions we did not find individuals with hypertension. The highest BP observed was of 140 x 90 in a 70-year-old indian. His result is consistent with what had been noted in 1975. Among the women, the highest level was of 130 x 60 in a 55-year-old female indian. The women maintained a lower level of BP as compared to the men of any age group. The average blood pressure showed a discrete increase going from 79.2 to 83.8 mmHg in the men and from 75.7 to 77.0 mmHg in the women. In this tribe we observed the habit of smoking in 30% of the individuals. Alcoholic beverage consumption is rare, physical activities remained constant and obesity is absent. As for the eating habits, with the decrease of hunting grounds, the indians acquired a more rural behavior with regular use of rice and beans. Salt is practically not added to the food. Competitiveness is not an acquired trait to that culture. CONCLUSION: In "isolated" populations that maintain their cultural traits and basic life styles, the occurrence of arterial hypertension is very rare and the increase in BP with age is modest and significant only for systolic.

[Arterial blood pressure in the remaining isolated black community of a quilombo north of Goiás-Kalunga].

PURPOSE: To evaluate, in an isolated group of black individuals from a quilombo--a previous stronghold of rebel slaves (Kalunga) in the north of Goiás, the arterial blood pressure, as it related to age, sex, salt consumption, physical activities, obesity, tobacco and alcoholic beverage consumption and social organization. METHODS: We studied 159 people (74 males and 85 females) representing 15% of the adult population. All measurements, were taken by the first author with the patient both sitting and supine, after 3 minutes of relaxation. This procedure was repeated 3 times and only the last measurement was used for research purposes. RESULTS: Of the studied cases only 10 individuals with hypertension (PAd > or = 95 mmHg) representing 6.28% of the population were found. Of the patients with hypertension 2 were between 18 and 29 years of age, 3 between 30 and 45 and 5 over 46 years old. They were 7 females and 3 males. We did not find any significant difference between sexes or any significant elevation in the medium BP value. The salt intake is relatively low among them and 81.7% of the population do not use any salt at all in their food. Alcohol consumption and the habit of smoking are moderate. They have intense physical activity and obesity is rare. The Kalunga have a cooperativist society and money is not frequently used as they favor the barter system. CONCLUSION: In isolated population that maintain their cultural traits and basic life style, not adding salt to their diet, not being obese and maintaining intense physical activities, the occurrence of arterial hypertension is rare and the increases in BP level with age is not significant.
