Abstract

Behavioral stressors may inhibit sodium excretion, potentially increasing plasma volume and elevating blood pressure during chronic exposure. Blood pressure regulation may be especially deranged during manipulations that further challenge the kidney, such as a diet high in salt content. The effects on blood pressure and other variables of combinedbehavioral stress (food/shock conflict) and dietary salt (12 g NaCl per day; 218 mEq Na+ per day) were examined in adult male baboons over the course of 1 year. Mean arterial pressure was not significantly elevated over baseline after 5 months of high dietary salt alone (6 +/- 5mmHg) bur was maximally elevated by an average of 17 (+/- 3 SEM) mmHgafter 5 months of combined salt and conflict stress. Control baboons showed no significant trends in mean arterial pressure across the sametime period. Individual subjects whose blood pressure was ''salt+stress resistant'' or ''salt+stress sensitive'' were differentiated by their degree of pressure diuresis and natriuresis, urinary free cortisol,and a behavioral index of stress sensitivity. The data indicate additive effects of chronic high dietary salt intake and behavioral stressors on blood pressure in nonhuman primates that are dependent on renal function and pituitary-adrenocortical activity.
