HealthDay News — Blacks have considerably increased risk for hypertension than whites through age 55 years, regardless of blood pressure levels through young adulthood, according to a study published online July 11 in the Journal of the American Heart Association.
S. Justin Thomas, Ph.D., from the University of Alabama at Birmingham, and colleagues calculated the cumulative incidence of hypertension from age 18 to 55 years in the Coronary Artery Risk Development in Young Adults study. Data were included for 3,890 participants without hypertension at baseline (age 18 to 30 years).
The researchers found that in black men, black women, white men, and white women, the cumulative incidence of hypertension by age 55 years was 75.5, 75.7, 54.5, and 40.0 percent, respectively. Blacks were more likely than whites to develop hypertension, with multivariable-adjusted hazard ratios of 1.97, 1.80, and 1.59 for those with systolic blood pressure/diastolic blood pressure <110 and 70, 110 to 119/70 to 74, and 120 to 129/75 to 79 mm Hg, respectively. Among blacks and whites, parental history of hypertension and higher body mass index, serum uric acid, and systolic blood pressure/diastolic blood pressure categories correlated with increased risk, while a higher Dietary Approaches to Stop Hypertension diet adherence score correlated with lower risk.
“Regardless of blood pressure level in young adulthood, blacks have a substantially higher risk for hypertension compared with whites through 55 years of age,” the authors write.
