Lipid Reactivity to Stress: II. Biological and Behavioral Influences

This study examined behavioral and physiological influences on lipid concentrations during acute and chronic stressors. One hundred men ( n = 92) and women ( n = 8) were tested during a chronic stressor and during 2 acute stressors. During chronic stress, diet, physical activity, exercise, and sleep...

Description
Summary:This study examined behavioral and physiological influences on lipid concentrations during acute and chronic stressors. One hundred men ( n = 92) and women ( n = 8) were tested during a chronic stressor and during 2 acute stressors. During chronic stress, diet, physical activity, exercise, and sleep were examined. During the acute stressors, catecholamines, cortisol, plasma volume, and cardiovascular responses were examined. None of the behavioral influences could explain the lipid response to chronic stress. Responses of the atherogenic lipids to acute stressors were not solely reflecting hemoconcentration of the plasma but were moderately correlated with cardiovascular, epinephrine, and cortisol reactivity. Diastolic blood pressure reactors to the acute stressors had larger lipid responses to the chronic stressor than did nonreactors. Elevations in blood lipids during stress are not artifacts and may be clinically significant.
