Hypertension is the number one risk factor for cardiovascular diseases worldwide and yet its diagnosis among adolescents, based on blood pressure percentiles which are age, height, and sex-specific, is complex. Our study intended to determine the suitability of blood pressure height index in defining adolescent hypertension among secondary school adolescents aged 12-17 years in Mbarara municipality, southwestern Uganda. Our study used data of 485 secondary school adolescents of which 173 were boys. Receiver operating characteristic curve analysis was performed to assess the performance of systolic blood pressure height index (SBPHI) and diastolic blood pressure height index (DBPHI) for screening for adolescent prehypertension and hypertension. The optimal systolic/diastolic thresholds for defining prehypertension were 0.70/0.43 mmHg/cm in boys and 0.76/0.43 in girls. The corresponding values for hypertension were 0.78/0.43 and 0.77/0.48 mmHg/cm, respectively. The negative predictive values were much higher (all ≥ 95%) for prehypertension and hypertension, while the positive predictive value was 100% for hypertension in both sexes. In conclusion, Blood pressure height index is simple and accurate for screening for prehypertension and hypertension in adolescents aged 12-17 years hence can be used for early screening of adolescents at high risk of hypertension but not its diagnosis.

使用血压高度指数定义乌干达西南部中学生的高血压。

高血压是全世界心血管疾病的第一大危险因素，但是根据年龄，身高和性别的血压百分位数，高血压在青少年中的诊断非常复杂。我们的研究旨在确定血压高度指数在乌干达西南部姆巴拉拉市定义12-17岁中学生青春期高血压中的适用性。我们的研究使用了485名中学生的数据，其中173名是男孩。进行受试者工作特征曲线分析，以评估收缩压高度指数（SBPHI）和舒张压高度指数（DBPHI）的性能，以筛查青少年高血压前期和高血压。定义高血压前期的最佳收缩/舒张阈值为0.70 / 0。男孩为43 mmHg / cm，女孩为0.76 / 0.43。高血压的相应值分别为0.78 / 0.43和0.77 / 0.48 mmHg / cm。高血压前期和高血压的阴性预测值要高得多（全部≥95％），而男女高血压的阳性预测值均为100％。总之，血压高度指数简单，准确，可用于筛查12-17岁青少年的高血压前期和高血压，因此可用于早期筛查具有高血压高风险的青少年，但不能用于诊断。
