Progression of the Epidemiological Transition in a rural South African setting: findings from population surveillance in Agincourt, 1993–2013
BMC public health, 2017Co-Authors: Chodziwadziwa W. Kabudula, Brian Houle, Mark A. Collinson, Kathleen Kahn, Francesc Xavier Gómez-olivé, Samuel J. Clark, Stephen TollmanAbstract:Virtually all low- and middle-income countries are undergoing an Epidemiological Transition whose progression is more varied than experienced in high-income countries. Observed changes in mortality and disease patterns reveal that the Transition in most low- and middle-income countries is characterized by reversals, partial changes and the simultaneous occurrence of different types of diseases of varying magnitude. Localized characterization of this shifting burden, frequently lacking, is essential to guide decentralised health and social systems on the effective targeting of limited resources. Based on a rigorous compilation of mortality data over two decades, this paper provides a comprehensive assessment of the Epidemiological Transition in a rural South African population. We estimate overall and cause-specific hazards of death as functions of sex, age and time period from mortality data from the Agincourt Health and socio-Demographic Surveillance System and conduct statistical tests of changes and differentials to assess the progression of the Epidemiological Transition over the period 1993–2013. From the early 1990s until 2007 the population experienced a reversal in its Epidemiological Transition, driven mostly by increased HIV/AIDS and TB related mortality. In recent years, the Transition is following a positive trajectory as a result of declining HIV/AIDS and TB related mortality. However, in most age groups the cause of death distribution is yet to reach the levels it occupied in the early 1990s. The Transition is also characterized by persistent gender differences with more rapid positive progression in females than males. This typical rural South African population is experiencing a protracted Epidemiological Transition. The intersection and interaction of HIV/AIDS and antiretroviral treatment, non-communicable disease risk factors and complex social and behavioral changes will impact on continued progress in reducing preventable mortality and improving health across the life course. Integrated healthcare planning and program delivery is required to improve access and adherence for HIV and non-communicable disease treatment. These findings from a local, rural setting over an extended period contribute to the evidence needed to inform further refinement and advancement of Epidemiological Transition theory.

migration and the Epidemiological Transition insights from the agincourt sub district of northeast south africa
Global Health Action, 2014Co-Authors: Mark A. Collinson, Kathleen Kahn, Samuel J. Clark, Michael J White, Philippe Bocquier, Stephen T Mcgarvey, Sulaimon Afolabi, Stephen TollmanAbstract:Background : Migration and urbanization are central to sustainable development and health, but data on temporal trends in defined populations are scarce. Healthy men and women migrate because opportunities for employment and betterment are not equally distributed geographically. The disruption can result in unhealthy exposures and environments and income returns for the origin household. Objectives : The objectives of the paper are to describe the patterns, levels, and trends of temporary migration in rural northeast South Africa; the mortality trends by cause category over the period 2000–2011; and the associations between temporary migration and mortality by broad cause of death categories. Method : Longitudinal, Agincourt Health and Demographic Surveillance System data are used in a continuous, survival time, competing-risk model. Findings : In rural, northeast South Africa, temporary migration, which involves migrants relocating mainly for work purposes and remaining linked to the rural household, is more important than age and sex in explaining variations in mortality, whatever the cause. In this setting, the changing relationship between temporary migration and communicable disease mortality is primarily affected by reduced exposure of the migrant to unhealthy conditions. The study suggests that the changing relationship between temporary migration and non-communicable disease mortality is mainly affected by increased livelihood benefits of longer duration migration. Conclusion : Since temporary migration is not associated with communicable diseases only, public health policies should account for population mobility whatever the targeted health risk. There is a need to strengthen the rural health care system, because migrants tend to return to the rural households when they need health care.
