Nutritional status and blood pressures of adults in northern Gazankulu
Abstract:
A random cluster sample survey of 432 adults aged 21-60 years was undertaken to increase available information on the nutritional status of the inhabitants of northern Gazankulu and to discover the prevalence and distribution of hypertension. Mainly owing to the migrant labour system, only 9,3% of the people in the sample were men. The present nutritional status of adults is adequate by anthropometric standards. The absence of a secular trend towards increased adult stature indicates that no major improvement in nutrition and socio-economic conditions has occurred in the last 20-60 years. Mean blood pressures were found to increase with age, but the prevalence of hypertension is low compared to urban populations.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Factors affecting Blood pressure
Physiological Factors:
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
