Effects of a traditional lifestyle on the cardiovascular risk profile: the Amondava population of the Brazilian Amazon. Comparison with matched African, Italian and Polish populations
Abstract
OBJECTIVE: To determine the relationships between lifestyle and cardiovascular risk factors among the Brazilian Amondava, one of the world's most isolated populations. DESIGN: Cross-sectional, population-based study. Four age- and sex-matched samples from Brazil Africa, Italy and Poland, representing different levels of modernization, were compared. Body weight, height, blood pressure, serum cholesterol and glycaemia were measured, and a standard questionnaire administered. Data concerning dietary habits and physical activity were collected. A personal socio-economic score was calculated, on the basis of type of economy, level of formal education, type of occupation, type of habitat, availability of piped water and electricity, main source of income, housing conditions, availability of radio, television or personal computer, knowledge of a second language, and organized health facilities. SETTING: Primary epidemiological screening, at an institution. RESULTS: Among the Amondava blood pressure was always <140/90 mm Hg, it did not increase with age and was not correlated with any other variable; 46.6% of subjects had systolic blood pressure <100 mm Hg. Blood pressure among the Amondava (109.6+/-11.1/69.5+/-6.4 mm Hg) was on average lower (P<0.0001) than in all other samples. Among the Amondava, the concentration of total cholesterol was always <200 mg/dl, i.e. similar to that of Africans whose diet included large amounts of vegetable foodstuffs; 90% had glycaemia (<80 mg/dl), and their mean value was the lowest (55.1+/-14.9 mg/dl) of all the groups. CONCLUSIONS: In addition to a possible genetic predisposition not analysed in this study, a traditional lifestyle (no contact with civilization, diet based on complex carbohydrates and vegetables, high energy expenditure) may protect against the development of hypertension, hypercholesterolaemia, and diabetes.

Among populations with traditional healthy lifestyle behaviors, the prevalences of obesity, dyslipidemia, hypertension, and diabetes mellitus are far less than in industrialized populations, even after adjustment for age.

Large disparities in both the prevalence of established risk factors and the rates of cardiovascular events in genetically similar populations both over time and across regions confirm that genetic effects are subordinate to lifestyle and environmental influences.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
