THE EGYPTIAN NATIONAL HYPERTENSION
PROJECT
(1991-1994)
INTRODUCTION
The Egyptian NHP is the first national hypertension
survey in an Arab country. It provides a large data base
not only concerning the prevalence of hypertension and hypertensive complications
among Egyptians, but
also about hypertensive and cardiovascular risk factors.
As such, the Egyptian NHP can serve as a model for similar
surveys in the developing world.
NHP was planned and executed by Egyptian scientists in collaboration with
experts from the USA. The Egyptian NHP has a number of unique features
besides being the first national hypertension survey in a developing country.
Measuring skin color reflectance and studying its relationship to blood
pressure in a large population was a special feature of NHP. The project
was one of the first surveys to conduct a large scale echocardiographic
field study in a developing country. The four blood pressure measurements,
the sample design and the rigorous quality control procedures, make one
feel confident in the validity of the information collected.
The data presented are the actual unweighted figures without any adjustment.
We hope that it will serve as a reference to all those who wish to discover
facts about hypertension in Egypt.
