The aim of this study was to determine which anthropometric indicator is the best marker of blood pressure in 10 - 15 year old children. A one-time cross sectional experimental design was used for this study. A total of 605, 10 - 15 year old males and 640 females were recruited from 44 randomly selected schools in the North-West Province, which formed part of the THUSA BANA study during 2000 and 2001. Anthropometric measurements selected, were primarily those described in Norton and Olds (1996). Blood pressure was measured with the Finapres in a non-invasive way. Data analysis was performed using Statistica 2001 (Stat Soft., Inc) for Windows 98. A forward stepwise discriminant analysis was performed to determine which anthropometric indicator is the best marker of high systolic and diastolic blood pressure in 10 - 15 year old children. According to the results of the discriminant analysis, percentage body fat were the best marker of both high systolic and diastolic blood pressure followed by triceps skinfold and abdomen girth. Prediction models for high systolic and diastolic blood pressure were developed for males and females, using the results of the discriminant analysis. This prediction models had an overall accuracy of 89.25% of predicting high systolic blood pressure and a 90.91% overall accuracy of predicting high diastolic blood pressure.
