目的 了解广州市儿童的高血压水平,探索采用血压身高比筛查广州市儿童高血压的最佳阈值。方法 采用整群随机抽样的方法 对广州市6~10岁的5 471名儿童进行血压及相关生长发育指标测量,采用受试者工作特征曲线确定血压身高比预测儿童高血压的能力及最佳阈值。结果 用于筛查广州市儿童高血压的收缩压身高比的最佳阈值为男生0.80 mmHg/cm,女生0.78 mmHg/cm;舒张压身高比的最佳阈值为男生0.51 mmHg/cm,女生0.49 mmHg/cm,阴性预测值高于阳性预测值,且均大于99%,阳性预测值较低,男生为17.2%,女生为15.9%。入组儿童高血压发病率为3.60%,其中男3.54%,女3.67%。结论 血压身高比可作为一种简单精确的指标筛查广州市6~10岁儿童高血压。
Abstract
Objective To investigate the prevalence of hypertension in children in Guangzhou,China and to determine the optimal cutoff values of blood pressure to height ratio (BPHR) for screening hypertensive children.Methods A total of 5 471 children aged 6~10 years old were enrolled by means of whole population random sampling.Blood pressure and anthropometric parameters were measured.The areas under receiver operating curves were applied to determine the predictive capability of BPHR to discern children with hypertension. Results The optimal cutoff values of systolic BPHR and diastolic BPHR were 0.80 mmHg/cm and 0.51 mmHg/cm in boys,and 0.78 mmHg/cm and 0.49 mmHg/cm in girls,respectively.The negative predictive values were larger than 99% for hypertension in both gender,the positive predictive values were 17.2% and 15.9%,respectively.The prevalence of hypertension were 3.54% in boys and 3.67% in girls,respectively.Conclusion BPHR is simple and accurate for screening hypertensive children aged 6~10 years old in Guangzhou.
