Objective: To examine changes in mortality in rural South Africa over the p
eriod 1992-1995 by age, sex and cause of death.
Design: As with much of sub-Saharan Africa, South Africa lacks effective vi
tal registration and information on mortality is lacking. The Agincourt dem
ographic and health surveillance system was established to inform health po
licy and practice with regard to rural subdistrict populations.
Methods: Prospective community-based study involving annual update of a hou
sehold census with enquiry into all birth, death and migration events. All
reported deaths (n = 1001) are the subject of a verbal autopsy.
Results: An increasing trend in overall mortality relative to general popul
ation growth in the study area is apparent. There is evidence for a reversa
l in the previously declining trend in mortality among women 20-44 years. A
comparison of 1992-1993 with 1994-1995 shows that most of the increase in
mortality is concentrated in the younger adult (20-49 year) age group. AIDS
and related diseases, particularly tuberculosis, appear primarily responsi
ble. Injuries and violence (especially homicide) and circulatory disease ar
e important, under-recognized causes of death, although their levels have r
emained constant over the period.
Conclusions: Mortality from AIDS and related diseases appears responsible f
or the probable reversal in mortality emerging in South Africa's rural nort
heast. Findings carry implications for the emerging system of decentralized
health care. (C) 1999 Lippincott Williams & Wilkins.
