Open-air archaeology plays a limited role in southern African Late Pleistocene research, with most studies focused on rock shelter assemblages. Recently, archaeologists have noted discrepancies in the composition of Late Pleistocene lithic assemblages between some of the region's open-air and rock shelter sites. For example, although relatively abundant in rock shelters, Late Pleistocene Later Stone Age (LSA, c. 44-12 kcal. BP) bipolar cores are rare in open-air contexts. In this paper, we assess this discrepancy by testing for differential preservation of specific artefact classes and sizes in semi-arid open-air conditions. We placed a replicated assemblage of miniaturised cores and flakes …

Increased salt intake leads to an increase in blood pressure and decreased sodium intake relative to the usual or increased intake results in lowered blood pressure in adults, with or without hypertension. Blood pressure is a strong proxy indicator for the risk of cardiovascular disease, coronary heart disease and strokes. Hypertension is estimated to have caused 9% of all deaths in South Africa in 2000. In 2008, 42% of men and 34% of women aged 35-44 years, and 60% of men and 50% of women aged 45-54 years, were hypertensive. More than 70% of both men and women older than …

The Cape Mountains of southern Africa exhibit an alpine-like topography in conjunction with some of the lowest denudation rates in the world. This presents an exception to the often-cited coupling of topography and denudation rates and suggests that steep slopes alone are not sufficient to incite the high denudation rates with which they are commonly associated. Within the Cape Mountains, slope angles are often in excess of 30° and relief frequently exceeds 1 km, yet 10Be-based catchment-averaged denudation rates vary between 2.32 ± 0.29 m/m.y. and 7.95 ± 0.90 m/m.y. We attribute the maintenance of rugged topography and suppression of …


Prevalence Of Household Food Poverty In South Africa: Results From A Large Nationally Representative Survey, Karen E. Charlton, Donald Rose Jan 2002

Prevalence Of Household Food Poverty In South Africa: Results From A Large Nationally Representative Survey, Karen E. Charlton, Donald Rose

OBJECTIVES: Household food insecurity is a major determinant of undernutrition, yet there is little information on its prevalence in the South African population. This paper assesses household food insecurity in South Africa using a quantitative and objective measure, known as food poverty, and provides prevalence estimates by geographic area and socio-economic condition. DESIGN: Secondary data analysis combining two sources: Statistics South Africa's household-based 1995 Income and Expenditure Survey; and the University of Port Elizabeth's Household Subsistence Level series, a nationally-conducted, market-based survey. SETTING: South Africa. SUBJECTS: A nationally representative sample of the entire country - stratified by race, province, and …


Nutrition And Ageing In Africa, Karen E. Charlton Jan 1999

Nutrition And Ageing In Africa, Karen E. Charlton

Faculty of Science, Medicine and Health - Papers: part A

Although the proportion of elderly people in African populations is much smaller than that in developed countries, the absolute numbers of older Africans are rapidly increasing. The huge majority of Africans live in poor economic circumstances and few countries are able to offer social assistance programs. The health and wellbeing of older persons largely depend on the integral existence of informal services, social support networks and kin support. African gerontologists have urged social welfare policy makers to take cognizance of self-organized intergenerational help systems already present on the continent, and to make public-sector finance available to support these systems. Nutrition …


Southern Africa Is Good Place To Research Role Of Fetal Malnutrition In Chronic Diseases, A Rp Walker, K E. Charlton Jan 1998

Southern Africa Is Good Place To Research Role Of Fetal Malnutrition In Chronic Diseases, A Rp Walker, K E. Charlton

Editor — We are interested in Scrimshaw's allusion to populations in Latin America in his editorial on the relation between fetal malnutrition and chronic disease in later life. There, in the 1960s, despite a high prevalence of low birth weight, the preva­ lence of atherosclerosis and of myocardial infarction was low.
