Stroke in rural South Africa - contributing to the little known about a big problem

Objectives. To describe the extent of mortality from cerebrovascular accident (CVA) in a rural South African population.Design. Annual demographic and health surveillance with verbal autopsy of all deaths, 1992 - 1995.Outcome measures. Stroke mortality rate by age and sex.Results. Stroke mortality increased with age and is higher in men than women over age 35. Proportionate mortality ratio from CVA: 10.3% of deaths in the 35 - 64-year age group.Conclusion. Cerebrovascular disease is an important cause of death in South Africa's rural north-east. Community-based research is needed to inform policy and practice

The implications of long term community involvement for the production and circulation of population knowledge

Demographic surveillance systems (DSS) depend on community acceptance and involvement to produce high quality longitudinal data. Ensuring community support also exposes power relations usually concealed in the research process. We discuss the Agincourt Health and Demographic Surveillance System in South Africa to argue that: 1) long-term presence and community involvement contribute to high response rates and data quality, 2) to maintain community support the project must demonstrate its usefulness, 3) reporting to community members provides valuable checks on the local relevance and comprehension of questions, and 4) community opinion can modify both wording and content of research questions.community, demographic surveillance system, fertility, health, knowledge, longitudinal, migration, mortality, South Africa

A hidden menace: Cardiovascular disease in South Africa and the costs of an inadequate policy response

The cardiovascular disease (CVD) burden in South Africa (SA) is increasing amongst all age groups and is predicted to become the prime contributor to overall morbidity and mortality in the over 50-year age group. Several factors contribute to this – an epidemiological transition, which has seen a rise in chronic non-communicable disease, and a demographic transition with much reduced fertility and a growing proportion of the population above 60 years. In parallel with unfolding urbanisation, the population burden of vascular risk factors namely hypertension, hypercholesterolemia, diabetes and obesity has increased. The scale of CVD burden poses a threat to the health system and calls for timely intervention. This paper discusses the burden of CVD in SA and current initiatives to address it. Evidence is presented from studies that focus on prevention including salt reduction and trans-fatty acids legislation. The economic and clinical impact of an inadequate private and public sector response is summarised. The paper documents lessons from other countries and proposes health systems strengthening measures that could improve care of patients with CVD

The stall in fertility decline in rural, northeast, South Africa: the contribution of a self-settled, Mozambican, refugee sub-population

Using longitudinal data from the Agincourt Health and socio-Demographic Surveillance System (HDSS) in rural South Africa, this paper examines the role of the fertility of self-settled, former Mozambican refugee sub-population on the stall in fertility decline in the Agincourt HDSS from 1993 to 2009. The Agincourt HDSS fertility trend is decomposed to quantify the relative contribution of the Mozambicans to fertility changes. Results show that fertility level declined by about 1.5 children per woman over the period and the level remain around 2.5 children per woman in the last eight years of the period examined suggesting a stall in fertility decline in the sub-district population covered by the HDSS. However, while the fertility of the Mozambicans fell consistently over the period, there was a reversal in the fertility decline of South African women residing in the area suggesting that the overall stalls are attributable to stalls in fertility decline among South African women.

Social patterns and differentials in the fertility transition in the context of HIV/AIDS: evidence from population surveillance, rural South Africa, 1993 - 2013.

BACKGROUND: Literature is limited on the effects of high prevalence HIV on fertility in the absence of treatment, and the effects of the introduction of sustained access to antiretroviral therapy (ART) on fertility. We summarize fertility patterns in rural northeast South Africa over 21 years during dynamic social and epidemiological change. METHODS: We use data for females aged 15-49 from the Agincourt health and socio-demographic surveillance system (1993-2013). We use discrete time event history analysis to summarize patterns in the probability of any birth. RESULTS: Overall fertility declined in 2001-2003, increased in 2004-2011, and then declined in 2012-2013. South Africans showed a similar pattern. Mozambicans showed a different pattern, with strong declines prior to 2003 before stalling during 2004-2007, and then continued fertility decline afterwards. There was an inverse gradient between fertility levels and household socioeconomic status. The gradient did not vary by time or nationality. CONCLUSIONS: The fertility transition in rural South Africa shows a pattern of decline until the height of the HIV/AIDS pandemic, with a resulting stall until further decline in the context of ART rollout. Fertility patterns are not homogenous among groups

Pension exposure and health:Evidence from a longitudinal study in South Africa

Social protection schemes have been expanding around the world with the objective of protecting older persons during retirement. While theoretically they have been seen as tools to improve individual wellbeing, there are few studies that evaluate whether social pensions can improve health. In this study, we exploit the change in eligibility criteria for the South African Old Age grant to estimate the association between pension exposure eligibility and health of older persons. For this, we use data from the Health and Aging in Africa: A longitudinal Study of an INDEPTH Community in South Africa (HAALSI) and model pension exposure in terms of its cumulative effect. Our results show that pension exposure is associated with better health as measured by a set of health indices. Disentangling these effects, we find that pension exposure is most likely to improve health through the delayed onset of physical disabilities in the elderly population. Our study highlights the relevance of social protection schemes as a mechanism to protect older persons physical health.</p
