| dc.description | Objective Cardiovascular risk factors were surveyed in two
Indian populations (Guarani, nU60; Tupinikin, nU496) and
in a non-Indian group (nU114) living in the same reserve in
southeast Brazilian coast. The relationship between an agedependent
blood pressure (BP) increase with salt
consumption was also investigated.
Methods Overnight (12 h) urine was collected to evaluate
Na excretion. Fasting glucose and lipids, anthropometry, BP,
ECG and carotid-femoral pulse wave velocity (PWV) were
measured in a clinic visit. Participation (318 men/352
women, age 20–94 years; meanU37.6W14.9 years)
comprised 80% of the eligible population.
Results The prevalence of hypertension, diabetes and high
cholesterol was similar in Tupinikins and in non-Indians and
higher than in Guaranis. The prevalence of smoking and
obesity was higher in the latter group. Hypertension and
diabetes were detected in only one individual of the
Guarani group. Mean BP adjusted to age and BMI was
significantly lower (P<0.01) in Guaranis (82.8W1.6mmHg)
than in Tupinikins (92.3W0.5mmHg) and non-Indians
(91.6W1.1 mmHg). Urinary Na excretion (mEq/12h),
however, was similar in the three groups
(GuaraniU94W40; TupinikinU105W56; non-
IndianU109W55; P>0.05). PWV (m/s) was lower (P<0.01)in Guarani (7.5W1.4) than in Tupinikins (8.8W2.2) and
non-Indians (8.4W2.0). Multiple regression analysis
showed that age and waist-to-hip ratio (WHR) were
independent predictors of SBP and DBP (r2U0.44) in
Tupinikins, whereas the WHR was the unique independent
predictor of BP variability in Guaranis (r2U0.22).
Conclusion Lower BP levels in Guaranis cannot be
explained by low salt intake observed in other primitive
populations. | |
