CONCLUSION • Hypertension has a high Global Burden.
• Shifting the resources and efforts towards prevention is recommended.
• One third of the screened school sample had abnormal BP.
• Males have higher BP.
• The independent variables correlated with BP were:• Age.• Gender• BMI.• Pulse.
• The nationality and school correlation with BP needs further studies.
