John Henryism과 혈압

Abstract

The Hypothesis was tested that the John Henryism would be associated with blood pressure and it would have interaction with stress-coping resources on the blood pressure measured by the Perceiived Social Support Scales(PSSS) in 168 persons undergoing the preemployment examinations comprised of 83 males and 85 females(mean age 19.4, S.D. 3.13), November 1988. The John Henryism Scales for Active Coping(JHAC12) was distributed normally with mean 45.6, standard deviation 6.2, median 4445, and range 26-59. The reliability coefficients was 0.79 for both sexes. The factor analysis yielded 3 factors which was extracted by principal component analysis. The main effect of social support on John Henryism was statistically significant(P=0.00), and interaction effect of sex and social support was significant also(P=0.02) and that of age and social support marginally(P=0.08). The main effect of John Henryism on blood pressure was negligible in both sexes but after adjusting for amounts of smoking and alcohal intake it became statistically significant(P=0.05) in male diastolic blood pressure. Men showed no interaction of John Henryism with social support. Among women, however, there was interaction with borderline significance(P=0.04) in diastolic blood pressure without any significant interaction. But the direction of the interaction supported the hypothesis. These results suggest that the interactions of John Henryism with stress-coping resoources on blood pressure may be present in socioeconomic-cultural settings other than American blacks' which were envisioned originally.
