Context: Oscillometric devices are preferred method for measuring blood pressure (BP) among children. Aims: This study measured BP among school-age children using a validated oscillometric device (Omron 705 IT®) and correlated the findings with the anthropometric parameters, with a view to determine the predictors of BP. Settings and Design: This was a cross-sectional, descriptive study. A multistage stratified random sampling technique was used in the selection of pupils from primary schools in Ilorin, Nigeria. Subjects and Methods: Two serial BPs were measured used using Omron 705 IT® with appropriate cuffs using “the fourth report” guideline and standard methods were used for measurement of anthropometrics. Statistical Analysis Used: Data were analyzed using SPSS version 20. Results: A total of 1745 primary school-aged children comprising of 873 males and 872 females were recruited. Anthropometric parameters were comparable between males and females. Mean systolic and diastolic BPs were 103.8 ± 11.0 mmHg and 61.3 ± 8.4 mmHg, respectively. Mean systolic BP was lower in males compared with females (102.9 ± 10.6 mmHg vs. 104.7 ± 11.3 mmHg, respectively,P= 0.001). Mean diastolic BP in males was lower compared with females (60.7 ± 8.3 mmHg vs. 61.8 ± 8.5 mmHg, P= 0.009). Most of the anthropometric parameters correlated with the BPs. Independent predictor of BP was weight, height, and body mass index (BMI), P < 0.001. Conclusions: There was a weak correlation between the oscillometric BPs and anthropometric parameters with weight, height, and BMI been the independent predictors of BP.
