Women with prehypertension in primary care - Risk profile on the basis of selected cardiovascular risk factors

A Question of Color

This study describes the relative influence of facial skin color, lifetime exposure to racial discrimination, chronic stress, and traditional prehypertension risk factors (family history of hypertension and age) on resting blood pressure and body mass index (BMI) among 196 southern African American (AA) female undergraduate students. Stepwise regression analyses indicated that skin color was the strongest predictor of systolic blood pressure (SBP), diastolic blood pressure (DBP), and BMI. Skin color, chronic stress, and family history of hypertension predicted 53% of the SBP variance. Skin color, chronic stress, and family history of hypertension predicted 30.2% of the DBP variance. Racism and age were not significant predictors of SBP or DBP. Of the variance in BMI, 33% was predicted by skin color, chronic stress, and racism. Age and family history of hypertension were not predictors of BMI. The current study provides evidence of the relationship of skin color and chronic stress to blood pressure among young southern AA women. The study identifies an important relationship between increased racial stress exposure and heavier BMIs, a predictor of prehypertensive risk.
