Key result
Compared with white women, black men had a higher prevalence of nocturnal hypertension (59.9% vs 18.4%; PR 2.01, 95% CI 1.43-2.82), as did black women (44.4%; PR 1.65, 95% CI 1.18-2.32).
Why the study?
Nocturnal hypertension and non-dipping blood pressure increase cardiovascular risk, but race and sex differences in these conditions were evaluated to determine disparities among black and white men and women.
Does the prevalence of nocturnal hypertension and non-dipping blood pressure differ among black and white men and women?
Cross-Sectional (n=767)
Does the prevalence of nocturnal hypertension and non-dipping blood pressure differ among black and white men and women?
Relative Risk: 2.01 (95% CI 1.43–2.82)
Absolute Event Rate: 59.9% vs 18.4%
Black men and women have a significantly higher prevalence of nocturnal hypertension and non-dipping systolic blood pressure compared to white women, highlighting racial disparities in adverse blood pressure patterns.

May inform targeted nocturnal BP assessment in black adults; extends observational data on racial disparities but leaves causality and practice change open.
Booth et al. (2019) conducted a cross-sectional in Nocturnal hypertension and non-dipping blood pressure (n=767). Black men vs. White women was evaluated on Nocturnal hypertension (PR 2.01, 95% CI 1.43-2.82). Compared with white women, black men had a higher prevalence of nocturnal hypertension (59.9% vs 18.4%; PR 2.01, 95% CI 1.43-2.82), as did black women (44.4%; PR 1.65, 95% CI 1.18-2.32).
