The prevalence of hypertension (HT) and blood pressure (BP) control varies among ethnic-racial groups, but studies on this issue and correlations between BP and body mass index (BMI) in the black Brazilian population are scarce.
Cross-sectional study in individuals included in the First Brazilian Hypertension Registry. Relationships between variables were analysed by a binary logistic regression analysis.
The study evaluated 2.191 (82.9%) non-Afro-descendant participants and 452 (17.1%) Afro-descendants. The median age was 61.9 years (55.3% women), the BMI was 28.4 kg/m² and the waist circumference (WC) was 93 cm in the former cohort. In the Afro-descendant group, the median age was 62.5 years (57.5% women), the was BMI 29.8 kg/m² and the was WC 98 cm. A significant correlation was identified between BMI and office diastolic BP (DBP) ( = 0.126; = 0.007) in Afro-descendants. These individuals had 1.40 times the chance of being obese compared to those of other ethnicities (95% CI: 1.14-1.72; < 0.001). Afro-descendant men had 0.78 times fewer chance of being obese compared to women (95% CI: 0.66-0.90; = 0.002), and 1.49 times higher chance (95% CI = 1.21-1.82; < 0.001) of having uncontrolled BP, with no differences with Afro-descendant women (HR 0.91; 95% CI = 0.78-1.07; < 0.258).
No correlations were found between office BP, BMI and WC, except for a very weak correlation between DBP and BMI in the Brazilian Afro-descendants, although they were 1.40 times more likely to be obese. In contrast, a significant correlation between SBP and BMI was observed in the non-Afro-descendants. Differences in blood pressure control were not identified between the sexes within each group, but only between ethnic groups, with people of African descent having a 1.49 times greater risk of uncontrolled hypertension compared to non-Afro-descendants.
高血压（HT）患病率及血压（BP）控制情况在不同种族群体中存在差异，但针对巴西黑人人群中该问题以及血压与体重指数（BMI）之间相关性的研究较少。
对纳入巴西首个高血压登记处的个体进行横断面研究。通过二元逻辑回归分析变量之间的关系。
该研究评估了2191名（82.9%）非非洲裔参与者和452名（17.1%）非洲裔参与者。在前一组队列中，年龄中位数为61.9岁（女性占55.3%），BMI为28.4kg/m²，腰围（WC）为93cm。在非洲裔组中，年龄中位数为62.5岁（女性占57.5%），BMI为29.8kg/m²，WC为98cm。在非洲裔人群中，BMI与诊室舒张压（DBP）之间存在显著相关性（ = 0.126； = 0.007）。与其他种族相比，这些个体肥胖的几率是其他种族的1.40倍（95%置信区间：1.14 - 1.72； < 0.001）。非洲裔男性肥胖的几率比女性少0.78倍（95%置信区间：0.66 - 0.90； = 0.002），血压未得到控制的几率比女性高1.49倍（95%置信区间 = 1.21 - 1.82； < 0.001），与非洲裔女性相比无差异（风险比0.91；95%置信区间 = 0.78 - 1.07； < 0.258）。
除了巴西非洲裔人群中DBP与BMI之间存在非常微弱的相关性外，未发现诊室血压、BMI和WC之间存在相关性，尽管他们肥胖的可能性是其他种族的1.40倍。相比之下，在非非洲裔人群中观察到收缩压（SBP）与BMI之间存在显著相关性。每组内不同性别之间未发现血压控制方面的差异，仅在种族群体之间存在差异，非洲裔人群高血压未得到控制的风险是非非洲裔人群的1.49倍。
