Cardiovascular diseases and alimentary comparison study: preliminary analysis from Brazil.
The Cardiovascular Diseases and Alimentary Comparison (CARDIAC) Study (1) was designed to study the relationship of dietary factors to blood pressure (BP) and other major cardiovascular disease (CVD) in widely different populations of both industralized and developing countries. The primary aim of the research was to test specific hypotheses linking the intake of certain dietary constituents, e.g., sodium (Na), potassium (K), calcium (Ca), and protein, to BP (core study). The final aim was to contribute to the scientific information base required to guide the formulation of dietary goals for the primary prevention of CVD. The results of the preliminary analysis of data from Brazil in 57 inhabitants (22 men and 35 women) suggest a nonsignificant statistical correlation of Na intake estimated by urinary Na excretion and diastolic BP (DBP) and systolic BP (SBP) (p greater than 0.05), K intake estimated by urinary K excretion for DBP and SBP (p greater than 0.05), and taurine intake estimated by taurine urinary excretion for DBP and SBP (p greater than 0.05). A positive correlation was found between body mass index (BMI) and BP (p less than 0.01), for both DBP and SBP.
