Abstract

Blood pressure to height ratio (BPHR) has been suggested as a simple method for screening children with hypertension, but its discriminatory ability in young children is not as good as that in older children. Using data of 89,664 Chinese children aged 7 to 11 years, the authors assessed whether modified BPHR (BP:eHT13) was better than BPHR in identifying young children with hypertension. BP:eHT13 was estimated as BP/(height+7×(13-age in years)). Using Youden's index, the thresholds of systolic/diastolic BP:eHT13 for identifying prehypertension and hypertension were 0.67/0.44 and 0.69/0.45, respectively. These proposed thresholds revealed high sensitivity, specificity, negative predictive value, and area under the curve (AUC), ranging from 0.874 to 0.999. In addition, BP:eHT13 showed better AUCs and fewer cutoff points than, if not similar to, two existing BPHR references. BP:eHT13 generally performed better than BPHR in discriminating BP abnormalities in young children and may improve early hypertension recognition and control.
