The disease burden of indigenous peoples has been augmented by the rising prevalence of obesity and hypertension in this population. This study assessed the ability of obesity indices to predict hypertension among indigenous adults of Peninsular Malaysia.
In this cross-sectional study, 482 adults (223 men, 259 women) aged ≥18 years old were measured for body mass index (BMI), waist circumference (WC), waist-height ratio (WHtR), waist-hip ratio (WHR), and blood pressure. Receiver operating characteristic (ROC) analysis was used to determine the predictive ability of obesity indices for hypertension in men and women. Gender-specific logistic regression analyses were done to examine the association between obesity, defined by BMI, WC, WHtR and WHR, and hypertension.
Prevalence of hypertension was 25.5%. Overall, WHtR was the best predictor of the presence of hypertension, in both men and women. The optimal WHtR cut-off values for hypertension were 0.45 and 0.52 in men and women, respectively. Obese adults with WHtR ≥0.5 had about two times increased odds of having hypertension compared to non-obese adults.
WHtR may serve as a simple and inexpensive screening tool to identify individuals with hypertension in this relatively difficult to reach population.
肥胖和高血压在原住民中的患病率不断上升，加重了该人群的疾病负担。本研究评估了肥胖指数预测马来西亚半岛原住民成年人高血压的能力。
在这项横断面研究中，对482名年龄≥18岁的成年人（223名男性，259名女性）测量了体重指数（BMI）、腰围（WC）、腰高比（WHtR）、腰臀比（WHR）和血压。采用受试者工作特征（ROC）分析来确定肥胖指数对男性和女性高血压的预测能力。进行了性别特异性逻辑回归分析，以检验由BMI、WC、WHtR和WHR定义的肥胖与高血压之间的关联。
高血压患病率为25.5%。总体而言，WHtR是男性和女性高血压存在的最佳预测指标。男性和女性高血压的最佳WHtR临界值分别为0.45和0.52。与非肥胖成年人相比，WHtR≥0.5的肥胖成年人患高血压的几率增加了约两倍。
在这个相对难以接触到的人群中，WHtR可作为一种简单且廉价的筛查工具，用于识别高血压患者。
