Extract: Blood pressure, diet, urinary electrolyte excretion, and body form were studied in 264 traditional nomadic herdsmen of the Qash'qai tribe, southern Iran. Interviews established biological age, any experience of nonnomadic living, and 24-h dietary recall. Height, weight, triceps skinfolds, and blood pressure were measured. Urine samples were analyzed for sodium, potassium, and creatinine. Samples of dietary staples were analyzed for selected nutrients and electrolyte content. Systolic, diastolic, and mean blood pressure in both males and females increased significantly with age. Body weight showed no tendency to increase with age in either sex. Systolic and mean blood pressure correlated with urinary sodium excretion in males and with urinary Na/K ratio in females. The data suggest that blood pressure trends in this population are related to habitual dietary electrolyte intake.
