To determine the predictive power of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR), and their respective cut-off points for high blood pressure (BP) screening in Brazilian children and adolescents.
Cross-sectional study conducted with 1,139 students aged 6 to 17years. Body weight, height, WC, and BP were measured. High BP was classified as systolic or diastolic ≥ 95th percentile. Receiver Operating Characteristic (ROC) curves were constructed, and the area under the curve, sensitivity, and specificity were calculated.
The prevalence of high BP was 27.0%. Anthropometric indices showed a significant association with high BP (accuracy ranging from 0.62 - 0.81), except for WHtR among male adolescents.Sensitivity was low, regardless of the anthropometric index, gender, and age group.
BMI, WC, and WHtR were associated with high BP, but the cut-off points tested showed low sensitivity. Determining specific cut-off points for each population can enable the use of anthropometric indices in high BP screening.
确定体重指数（BMI）、腰围（WC）和腰高比（WHtR）在巴西儿童和青少年高血压（BP）筛查中的预测能力及其各自的切点。
对1139名6至17岁的学生进行横断面研究。测量体重、身高、腰围和血压。高血压定义为收缩压或舒张压≥第95百分位数。构建受试者工作特征（ROC）曲线，并计算曲线下面积、敏感性和特异性。
高血压患病率为27.0%。人体测量指数与高血压有显著关联（准确性范围为0.62 - 0.81），男性青少年的腰高比除外。无论人体测量指数、性别和年龄组如何，敏感性都较低。
BMI、WC和WHtR与高血压有关，但所测试的切点敏感性较低。为每个人口群体确定特定的切点可以使人体测量指数用于高血压筛查。
