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.

Blood pressure among the Amondava (109.6 ± 11.1/69.5 ± 6.4 mmHg) 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. (...)
