Association between stress and blood pressure variation in a Caribbean population

ABSTRACT

Based on the work of Selye (The Stress of Life, New York McGraw Hill, 1976) it is hypothesized that stress can produce physiological abnormalities, i.e. elevated blood pressure, and that social variables can be used as indicators or risk factors for diseases. It is theorized that deviations from acceptable social patterns or traditional life-styles can produce stressful conditions that are associated with disease and that these situations can be demonstrated by examination of certain social characteristics. This association is examined among the Black Caribs of St. Vincent, West Indies. The social variables included in this analysis are marital status (single, married, widowed, or separated), frequency of church attendance (frequently, sometimes, seldom, or never), years of education, and number of children (for women only). The findings show that single individuals have higher pressures than married subjects and that males who never attended church have higher pressures than men who frequently attend church; a relationship was not demonstrated for females. Among males, as the years of education was increased, blood pressure also increased, but for females, increased education was associated with lower pressures. Family size was not associated with systolic or diastolic pressure. The analysis of these selected social variables suggest that these variables influence male systolic and diastolic pressures, but only female diastolic pressure. (AU)
