This research, developed among college students Lugango city - Angola, aimed at identifying the prevalence of systemic arterial hypertension (SAH) and associated risk factors in this population. The theoretical reference adopted was the Lalonde model for Population health, with elements from human biology, environment, life style and management of health services. The population studied was composed of 667 college students from 18 to 55 years old, mean 29 and standard deviation of 8. The data was obtained by means of individual interviews, performed in the college where they studied.

The body weight assessment was evaluated utilizing a portable balance; the height assessment with a non-elastic tape measure, fixed in a flat wall 50 centimeters from the floor. The arterial pressure was assessed by the auscultatory method, with aneroid sphygmomanometers tested and properly calibrated and rubber bladder compatible to the arm circumference of each individual. Data related to human biology indicated that 17.1% of the interviewed were over weight; 3.2% were obese. The prevalence of SAH was of 23.5%. When the familiar antecedents were analyzed, 40.3% declared that at least one of their parents presented hypertension and 22.0% had, at least, one first grade parent with the disease. With respect to environment; 36.1% had exclusive dedication to studies; 55.5% worked on the public service, 28.9% did not received individual income; 51.3% received an individual income of up to 250 dollars.

The data show a high prevalence of SAH, considering that most of the subjects were young; a lack of information about arterial hypertension and the presence of auto-created habits that are considered as risk factors to hypertensive and cardiovascular diseases that can be modified by means of implementation of educative programs with actions directed to health promotion, in order to control these diseases.
