Hypertension in a Caribbean Population

Abstract

This cross-sectional study presents an assessment of factors associated with elevated blood pressure in Seventh-Day Adventists in the Caribbean. Four-hundred-thirty-three subjects were randomly selected from the English-speaking Caribbean population. Subjects ranged in age from twenty-one to sixty; 150 were males and 283 females. Eighty percent were Negroes of African descent, 12 percent mixed, 8 percent Indians of East Indian descent, and 3 percent of Spanish background. The study utilized the PRECEDE model developed by Green and associates to examine factors for hypertension. A positive correlation was found between body mass index (weight in Kg/height in M²) and hypertension in both sexes. Age was also significantly associated with hypertension. Normotensive females had a slightly higher intake of potassium than hypertensives, while hypertensive males tended to have higher levels of calcium. Other factors, such as parental history of blood pressure, vegetarian diet, sugar and fat intake, or Type A/B personality showed no relationship to hypertension. The vast majority of participants were Type B. This study provides baseline information for use in selecting those features which will be emphasized in a health education program, as well as baseline data for evaluation of health education in the Caribbean.
