Repressive Coping and Blood Measures of Disease Risk: Lipids and Endocrine and Immunological Responses to a Laboratory Stressor1

Relations between repressive coping and a variety of health‐related variahles including insulin, lipids, catecholamines, and cellular immune components, were investigated in a laboratory study of acute stress among a sample of healthy male college students (N ‐ 83). Compared to nonrepressors, at baseline, repressors had fewer numbers of circulating CD4 (T‐helper) cells, greater numbers of natural killer (NK) cells. lower high‐density lipoprotein (HDL), a higher total/HDL cholesterol ratio, and higher fasting insulin levels. In response to an acute laboratory stressor (Stroop Color Word Conflict Test). repressors demonstrated an attenuated increase in the number of circulating NK cells compared to nonrepressors. Confounds such as physical activity, age, and smoking were unrelated to the dependent measures.
