This briefing note is based on work prepared by Dr Jane Doherty and Staff of the MRC/Wits Agincourt
Unit, and is primarily based on the results of the annual census results from 1994 to 2010 and the
collection of articles that appear in a special supplement (no. 69 of 2007) of the Scandinavian Journal
of Public Health entitled Health, population and social transitions in rural South Africa. The
supplement showcases research conducted by a Health and Socio-Demographic Surveillance System in
rural South Africa. The supplement was edited by Stephen Tollman and Kathleen Kahn of the School of
Public Health (University of the Witwatersrand) and the MRC/Wits Rural Public Health and Health
Transitions Research Unit (Agincourt), South Africa. All photos were taken by Paul Weinburg.

INTRODUCTION
This annual research brief presents health and demographic indicators and scientific results from nested
projects derived from the Agincourt Health and Demographic Surveillance System site (Agincourt HDSS), located
in the Agincourt area of the Bushbuckridge Local Municipality, Ehlanzeni District, Mpumalanga Province of South
Africa.
Purpose of the annual report
This brief aims to provide information useful to various government and non-governmental service providers
who may use the data to plan their services. In addition, it will be useful to all researchers and students
collaborating with the MRC/Wits Agincourt unit. The information may be used in any way – although it is
requested the work is acknowledged as follows: “Annual Research Brief - MRC/Wits Rural Public Health And
Health Transitions Research Unit (Agincourt), Vol 1:Nov 2011”. Contact detials are on the back of the document
should you want to make further requests for information.
WHERE AND WHAT IS THE AGINCOURT HDSS?
The Agincourt health and socio-demographic surveillance system is the research foundation of the MRC/Wits
Rural Public Health and Health Transitions Research Unit (Agincourt). The Agincourt HDSS site, measuring some
420 sq km, extended in 2007, and currently covering 87,040 people living in 14,382 households and 24 villages,
lies in South Africa’s semi-arid rural north-east. Part of the Bushbuckridge ‘poverty node’ it has long been a
labour sending area with limited employment opportunities despite a population density above 200 persons per
sq km. Located only 40km west of the Mozambican border, the area can be regarded as a cross-border region of
rural southern Africa – indeed former Mozambicans make up about a third of the Agincourt population.
In the apartheid era, the Agincourt area formed part of the black ‘homeland’, Gazankulu. This legacy shapes the
lives of its inhabitants today: farms are too small to support subsistence, land tenure is still under traditional
authority, the local economy is not well-developed and many families are dependent on labour migrancy and
government social security grants for their livelihoods. Poverty is widespread and the HIV/AIDS epidemic casts
its shadow over many of the changes experienced by the community since the first democratic elections in 1994.
WHAT IS A HEALTH AND SOCIO-DEMOGRAPHIC SURVEILLANCE SYSTEM?
Information on health indicators is usually very weak in communities with poor infrastructure and health
systems. It is precisely in these communities, however, that good information is required in order to improve
health and health equity.
Health and socio-demographic surveillance is a response to this problem. It generates accurate information in
communities about which little is usually known. Over a period of time, data are collected through regular visits
to households and interviews with household members.
These ‘longitudinal’ data allow the analysis of population
‘[W]e submit that South Africa today faces a real
“crisis of evidence.” This is reflected in the
dynamics as well as health and social change, in order to
limited availability of empirically-derived
inform ongoing policy and practice.
population-based data, weak investments to
support their production, and limited public
sector capacity to absorb, sift, interpret and
respond to findings.’ [1]
Because of the long-term presence of researchers in a
community, surveillance systems have to pay special attention
to relationships with the community. To this end, the LINC
(Learning, Information Dissemination and Networking with
the Community) office was established, charged with ensuring partnerships between the unit, the study
communities and the local service provider.This and other features make surveillance systems expensive to set

up and complex to run. However, once established, they are powerful mechanisms for generating accurate and
relevant information (see Box 1). As a result, the number of surveillance sites around the world has proliferated
over the past two decades. These sites are linked through an active global network called INDEPTH.1
Participation in the network strengthens the ability of sites to articulate and address the essential questions
confronting poor communities, especially in rural areas.

Box 1: Benefits of a Health and Socio-Demographic Surveillance System
The denominator population of a geographically defined area is reliably known: this
makes it possible to calculate reliable rates.
It is possible to track conditions over time and understand complex, dynamic processes
that affect households: this is not possible with cross-sectional studies.
The site’s research infrastructure can be used as a platform in which to ‘nest’
additional, specialized studies, and established relationships with the community make
it easier to engage with the community during future work: this makes the overall
research exercise cost-effective.
As all households and household members are registered, it becomes easier to select
relevant participants for research studies (e.g. households which have experienced a
recent death).
It becomes possible to consider the findings generated by different studies together,
providing richer insight into the community.
It is possible to evaluate the impact of interventions.
Preserving the relationship with the community helps to ensure that research is
relevant [1].
An example of population trends that are possible to quantify in demographic surveillance is shown in the two
population pyramids in Figure 2. These population pyramids show a rapid transition in the villages in the
Agincourt HDSS between 1994 and 2010 from a pyramid typical of a developing nation with a wide base showing
a high fertility rate, to a pyramid with a narrower base in 2010 (excluding new villages added in 2007) showing a
lower fertility rate, and the 0-4 year olds from 1994 moving up to form the wide mid section of 15-19 and 20-24
year olds in 2010. The result of the large numbers of 0-4 year old females in 1994 reaching child bearing age in
2010 means that there is a concurrent increase in the numbers of 0-4 year olds in 2010. Note also the slight
increase in the number of older people in 2010, possibly owing to better access to health care and reduction in
poverty probably due to increases in social security. These pyramids serve to show just one trend illustrated by
the data emanating from the annual census run by the Agincourt HDSS.

THE AGINCOURT HEALTH AND SOCIO DEMOGRAPHIC SURVEILLANCE SYSTEM
Annual Census
The Agincourt HDSS was initiated in 1992 and is a founding member of INDEPTH, the global network of similar
sites. Once a year, the Agincourt HDSS carries out a census of all 14 500 households, identifying births, deaths
and instances of in- and out-migration. Subsequently, a verbal ‘autopsy’ is conducted by speaking to members of
households where a death has occurred: this is

Additional modules
Additional modules are also added periodically to the census, in the form of one or two page questionnaires.
This allows for cost effective data collection of information other than the purely demographic data (births,
deaths, in and out migrations) collected annually. Figure 3 shows the additional modules collected so far by the
Agincourt HDSS and the years in which they were collected.

Two examples of simple data that can be extracted from the module data are included in Figures 4 and 5 below.
Figure 4 shows data from the Socio Economic Status (SES) module and shows how households use of power to
cook has changed between 2001 and 2009. The percentage of households using electricity to cook is steadily
rising, and the percentage of households using wood to cook is steadily decreasing.

Figure 5 shows data from the education module conducted in 2009. Almost 90% of children from ages 8 to 13
were attending school in 2009. However, from age 13 to 18 there is a steep drop out until there were only 70%
of 18 years attending school in the same year.

Figures 4 and 5 show very simple data from the additional modules, but researchers also use the module data
for more complex analysis, such as showing how socio economic status and education status of mothers could
affect the health of children in the study site.
Specialized nested studies
Additional specialized nested studies are conducted periodically, and increasingly regularly. Thus, a special set
of questions may be added to the survey questionnaires administered during the census (for example, on child
health - the Growth studies, epilepsy - the SEEDS study, or stroke - the SASPI study). Alternatively, a new study
which a completely different might be conducted on a sample of households (for example, evaluating the impact
of conditional cash transfers on adolescent girls’ school attendance and incidence of HIV - the current Swa
Koteka HPTN 068 study, or in the past, the RENEWAL study). Additional information on all current nested
studies is included later in this report, and a few key results from a previous nested study are included below.
The RENEWAL Study
The RENEWAL study investigated the relationship between household experience of the death of a prime-age
adult member, household food security, and the use of natural resources in a sample of 290 households. The
Agincourt HDSS was used to select a random sample of roughly equal numbers of households that had
experienced either 1) an adult death due to HIV/AIDS, 2) a sudden adult death due to some other cause (e.g.
heart attack), 3) or no adult death in the last two years. A detailed questionnaire was used to collect data on
household use of natural resources and food security among these households.
Households that had experienced the death of a prime-age adult, regardless of the cause, were less food secure
than households that had not experienced an adult death over the same period. For most measures of food
security, it was the households impacted by a sudden non-HIV/AIDS death that were most severely impacted
Annual Research Brief - MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt). Vol 1, Nov 2011
10
(e.g. Figure 6). This was probably because such a death was totally unexpected, casting the household into crisis
without much time to adapt in the short term. Such people were also more likely to have been a bread-winner
before they died, compared to those who died from HIV/AIDS. However, regardless of experience of an adult
death, the poorest households were the least food secure.
There was not much difference in the use of natural resources between the three categories of households.
However, households that had lost an adult member in the last two years were much more likely than unimpacted households to state that they used a range of natural resources specifically to save money (Figure 7).
The use of natural resources thus potentially buffers households from some of the economic impacts of losing a
prime-age adult.

HEALTH, DEMOGRAPHIC AND SOCIAL TRANSITIONS IN THE AGINCOURT HDSS: THE
EVIDENCE
Over time, the research focus of the site has expanded from basic demographic and health status analysis to
comprehensive exploration of the complex health, population and social changes affecting the Agincourt people.
A distinctive feature of the Agincourt research is that it is truly multi-disciplinary, drawing on the strengths of
different theoretical frameworks and implementing a host of quantitative and qualitative methods.
Now, after 19 years in the field, the Agincourt HDSS is a mature research site with sophisticated data
management capacity [3]. It has generated a substantive body of work and achieved international recognition.
Some details from the Agincourt work are summarized below.
The Agincourt surveillance site has shown that, since its inception, the community has undergone rapid health,
demographic and social change: the supposed transition from diseases of poverty to diseases of affluence has
become protracted and, in some cases, inverted; health and health inequity worsened but mortality seems to be
decreasing; household composition is fluid and the roles and relationships of household members are changing.
Mortality
‘[T]hese discussions of life in the post-apartheid milieu
When the Agincourt surveillance site was initiated evoked an environment within which illness and
in the early 1990s, death rates were relatively low subsequent death proliferates … [A] heightened sense of
for a rural area in Africa. Since then, rapidly fragility of life infuses the experience of everyday life in
worsening death rates among young adults and Agincourt.’ [4:141]
young children saw a reversal of long-term mortality trends in these age groups [4] (See Box 2). However, more
recent evidence from the DSS suggests that there might be a reversal in death rates – possibly due to increased
access to anti retrovirals (see Figure 8).
Figure 8: Trends in life expectancy Agincourt HDSS 1992-2010
Emerging and persistent health problems
HIV/AIDS has become the leading cause of death among young adults and young children and has had a
profound effect on fertility, migration and familial arrangements. Research at Agincourt is seeking to
understand how the community makes sense of this phenomenon. One study found that community members
Annual Research Brief - MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt). Vol 1, Nov 2011
12
provide cultural explanations for ‘bad death’ (AIDS death): these centre on the erosion of cultural norms and
traditions and the consequences for physical health of ‘cultural lapses’ [5]. In this context, scientific
explanations and therapies have limited appeal. This is confirmed by another study which found that folk beliefs
about illness and its causes deter people from seeking life-saving treatment – such as antiretrovirals – from
Western health services [6]. When this is the case, disease transmission remains unchecked.
The HIV/AIDS epidemic has been accompanied by the resurgence of tuberculosis which has also reversed
favourable trends since the 1950s. It is a cause for concern that only 70% of prevalent pulmonary TB cases that
were identified by an Agincourt study in the permanent population were detected by the health service: 15%
were undiagnosed in the community and a further 15% died of the disease prior to diagnosis [2]. Most of these
cases had presented repeatedly to the health service.
Box 2: Mortality in Agincourt

Death rates increased since the mid-1990s to the mid 2000s.
Increases were most marked for:
o young adults between 20 and 49;
o children under 5; and
o females.
There is an increase in mortality amongst older women between the
ages of 50 and 64.
There was been a rapid decline in life expectancy:
o a 12-year decline in females; and
o a 14-year decline in males. [4].
Unpublished results from more recent surveys indicate that there
might be a reversal of the increase in mortality
Non-communicable disease has placed an additional burden on a community that already suffers from the
traditional diseases of poverty. Lifestyle, dietary and occupational changes have made obesity, hypertension
and diabetes major public health issues: an unexpected finding is that these problems are most severe in older
women [7]. A startling 43% of people 35 and over have hypertension but few are receiving treatment: it is likely
that untreated hypertension is a causal factor in the high death rate from strokes. In the absence of health
system intervention, Agincourt is likely to be at risk of increasing cardiovascular disease [8].
Indeed, recent data (Figure 9) suggests that the most problematic non communicable disease is in fact
cardiovascular disease, and this has persisted over the years of surveillance. The unit and collaborating
researchers are currently working with the National Department of Health in order to develop and evaluate an
intervention study aimed at reducing the effects of hypertension. It is hoped that this study will go into the field
in September 2011.

Malnutrition amongst children is persistent with many children not attaining their potential weight and height.
Mortality rates from malnutrition are high at 25%. HIV/AIDS contributes to this problem but one of the
Agincourt studies found that many of the traditional risk factors remain important – food insecurity, unhealthy
feeding practices, poor access to a quality health system, disruptions to family structure and poor access to child
support grants [9]. A striking finding of this research is that the number of women practicing exclusive
breastfeeding is low; supplementary foods are introduced early with possibly negative implications for child
health.
A separate study explored the social context of childrens’ nutritional status, identifying parental and residential
factors that are important: nutrition is compromised in the absence of a mother within the house and the lack
of financial support from a father [10]. Both studies confirmed, for the first time, that children born after other
siblings – that is, lower in the birth order - tend to be worse off.
Rapidly changing households
Fertility
In the Agincourt area there has been a consistent decline in fertility over the past 25 years, including amongst
adolescents [11]. The net reproduction rate has declined much faster than expected for a rural, African area:
Agincourt is one of the first sites in which this phenomenon has been recorded. The reasons for declining
fertility are complex, including increased use of contraception. Migration has certainly played a role and
HIV/AIDS has probably been responsible for about 20% of the fall.
Adolescent pregnancy is a ‘hot topic’ in South Africa presently. Table 2 tells a very interesting story from the
Agincourt HDSS data. Although adolescent pregnancies as a percentage of total pregnancies has indeed risen
between 1996 and 2007, the actual rate of teenage pregnancy has decreased rate. Total fertility rate across all
women of child bearing age has decreased [11], but it has just not decreased as fast in adolescents. We await
data from 2010 to learn more about this apparent trend.

Household composition
Over recent years, average household size has decreased, the proportion of female-headed households has
increased and the proportion of households with at least one maternal orphan has doubled [12]. Again,
migration and HIV/AIDS have probably played an important role in these changes. Contrary to expectations,
Agincourt has not yet seen an increase in ‘fragile families’ such as child-headed households or skippedgeneration families (where grandparents and children live together in the absence of working-age adults [12]. In
fact, national datasets that suggest there is an increase in single person households are not supported by
research in Agincourt where there is no evidence of individuals becoming more isolated residentially. On the
contrary, it seems more likely that the future, in this region at least, will see an increase in the proportion of
three-generation households [13]. Given the importance of the extended family, especially in protecting child
health, this is a positive factor.
Migration
As intimated already, migration dynamics have important implications for the Agincourt population: ironically,
although migration supports livelihoods it can also jeopardize health. Increasing numbers of people are seeking
employment outside of Agincourt and increasing numbers of women are included in this migration, changing
family arrangements. At the same time, adults who have migrated return to their village when they are seriously
ill and eventually die there, mainly from HIV/AIDS and TB. This research challenges notions of the permanency of
migration and provides strong evidence of the close ties between rural and urban areas in the form of ‘circular’
migration [14].
‘Returning home to die’ seems to have increased in recent years, imposing a new burden on families and local
health services [15]. Apart from the human suffering involved, there are costs to the household in the form of
the cessation of remittances, increased household health expenditure for health care and funerals and the
opportunity cost of caring for a severely ill person. Migration patterns like these also foster disease transmission
and pose a challenge to health information systems that attempt to track the occurrence of ill-health and
utilization of health services.

Throughout the developing world rural households that are unable to sustain themselves with local resources
use migration to access opportunities and employment elsewhere [16]. Often people with special skills or
higher education use migration to participate in the urban economy and get higher returns for their skills.
Poverty is a key feature in South Africa’s rural areas due to half a century of socially repressive laws with
geographical policies locating poor families in rural areas [17]. Labour migration was a cornerstone of apartheid,
but, nowadays, it is one of the prime strategies used by rural households to kick back against poverty. Despite
the removal of apartheid restrictions the level of temporary migration is increasing as described below [14].
Although this means that many people leave rural areas to work in urban settings it does not mean that they
become permanently embedded in the city. For many rural residents the trip may be short or long in duration
but often involves eventual return to the rural household. Sometimes migrants visit for family events like births,
marriages and funerals. Often over Christmas and Easter holidays the rural villages swell with returning migrants
coming back to be with family and friends. Sometimes when migrants get sick they return to be cared for by
their families [15]. Also, when migrants retire they often return to rural households. Therefore, there are twoway flows between South Africa’s cities and rural areas, which are represented in the data below [18:19]. The
dynamic nature of migration in South Africa is often misunderstood and conceived of as a one-way trip to an
urban area, so this chapter helps to rebalance some of that misunderstanding.
Migration and households
Migration is generally good for the socio-economic status of the household left behind. Although not all
migrants are able to find employment, those that do usually send money back to rural households. This can
relieve pressure on household budgets and even translate into more assets. Both male and female labour
migration is helpful for the economy of rural households. There is a basic relationship between migration and
households, such that it is better-off households that can afford to send a migrant and they usually benefit from
the migrant’s remittances, which helps them to remain better-off. However, even poorer households that are
able to send a migrant often obtain economic benefit in return [20].
Regarding the health of household members, better income can translate into better health, but there are also
health risks and challenges that arise from migration itself. In many parts of southern Africa there has been an
important link made between certain forms of migration and HIV transmission. The first issue is the exposure to
outside partners due to the break in regular sexual relations which expose the migrant and their home spouse to
sexually transmitted illness. In addition, some employments are associated with chronic infectious diseases like
tuberculosis in certain mining sectors. HIV and TB are inter-connected chronic infectious diseases that have
emerged and spread through migration.
On a more subtle level migration can involve social change and moving from a traditional to a more modern
setting can change people’s outlooks, diets and life-styles. This can include increased risks of smoking, alcohol
use, and in-take of salt, sugar and consuming unhealthy oils. For many migrants there is a background of stress
Annual Research Brief - MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt). Vol 1, Nov 2011
16
associated with disruption from home brought about by migration. If the migration is successful there may be
an associated risk of cardiovascular and other life-style related chronic illnesses.
The kinds of interventions that can lessen the health costs of migration include cheaper and safer transport
between home and work-place, accessible and affordable services and food availability in poor urban settings,
and using patient retained medical records, so that chronic medication can be started in an urban clinic or
hospital and continued by the health system in the rural setting if a migrant returns home.
Trends in migration patterns in the Agincourt HDSS Site.
Temporary migration occurs when a person migrates from a rural household without the intention of
permanently leaving, but remains part of the rural household. Usually, if the migration is successful, some
money flows back to the household in the form of remittances. It is not always money that is remitted and
migrants are often an important source of food, clothing or other investments in the rural household, like
building materials or appliances [21].
Some age-groups in the population are more likely to be temporary migrants. Figure 10 shows the trends in
temporary migration for men and women of different age-groups over a sixteen year period. Men aged 30-44
years are the most likely to migrate. Sixty-five percent of men in this age-group migrate. Older adult men also
migrate intensively with an average of 55% to 60% of the age-group 45-59 years migrating.
Figure 10: Trends in proportion of temporary migrants Agincourt HDSS site 1992 -2008
It can be seen that there has been an increase in the number of young male migrants aged 15-29 years. From
the early 1990s to the late 2000s the proportion of young men migrating each year has doubled from about 20%
(one in five young men) to 40% (two in five young men). Young men are increasingly mobile and move between
rural and urban areas.
It can also be seen that women of all adult age groups are increasingly becoming temporary migrants. Women
are now much more likely to migrate than in the past, especially young women aged 15-29 years. The reason for
women migrating varies. Mostly it is for work on game farms or commercial farms, or to a town or city for
domestic work or other jobs. Also, women migrate to sell rural produce in urban areas. For very poor
households in the population the income from female temporary migrants is a critical source of income. Young
women (and men) also migrate for better education, especially from better off households.

Where do temporary migrants go?
Table 3 shows the types of destinations that men and women are temporarily migrating to. Temporary
migration occurs most frequently to destinations in large cities and towns and much less to nearby villages.
Shorter distance migration tends to be permanent migration, mainly due to marriage, which is described below
in Table 4. Both men and women temporarily migrate to nearby farms, but it is much more likely to be a
destination for women. Both men and women temporarily migrate to towns and secondary urban centres, like
Nelspruit, Giyani, Witbank and Middleburg, but mostly these are destinations for men. The primary metropolis
of Johannesburg/Pretoria/Mid-rand (Gauteng) is the most important destination for temporary migrants, both
male and female.

Where do permanent migrants go to and come from?
It is clear in Table 4 that the largest proportion of permanent migrants move within the sub-district, so-called
village to village moves. Seventy-nine percent of permanent in-migrations are from other villages and 75% of
out-migrations are to other villages. These proportions differ because there is more movement into the subdistrict villages than out of sub-district villages. There is a net in- migration of 3%, so in terms of village-to-village
moves, also known as local mobility, the sub-district is gaining people from other villages.
It is noteworthy that nearby towns are attracting people from rural villages. The highest proportion of moves of
this kind were to Mkhuhlu, a town that developed in the late 1980’s, on the main road leading to Hazyview. The
mechanism involved in this migration has important socio-political implications. Prior to 1986, when the Influx
Control laws were abolished, movement between homeland areas was impossible, movement to and from
urban areas strictly controlled, and, although less documented, movement within the ‘homeland’ areas was also
extremely difficult. Traditional authorities usually aligned with the state in Pretoria, strongly encouraged people
to stay within small, well-defined chieftaincies. With the coming to power of the African National Congress in
1994 the Reconstruction and Development Programme was launched and a democratically elected committee
placed in charge of community affairs at a village level. In the late 1980’s Mkhuhlu was somewhat larger than a
village, with an established hospital, private health facilities, schools and public services. When people arrived to
settle in 1994 the elected civic leadership allowed settlement on land that had been previously been held as
common grazing land by the traditional authority. Once settlement started the word got around, and the chief
could not prevent a flood of families from villages to the newly budding town. The attraction of towns like these
remains important and is due to the availability of services, like health and education, and basic comforts like
tap-water and electricity. These are sufficient attractions, since employment opportunities in the town remained
low [22].
Bi-directional permanent migration to and from Gauteng Province is more balanced than migration to and from
nearby towns. There are modest flows from the field-site population to Gauteng (4.8% of moves) and returning
from Gauteng to the field-site population (5.4 % of moves).
The rural sub-district of the Agincourt field site is close to the border with Mozambique. The civil war in
Mozambique in the 1980’s resulted in the settlements of former refugees in north eastern South Africa. As a
consequence of their history they are less able to acquire property, engage in the labour market or access
government services, resulting in higher levels of poverty compared to South African households. There are still
population flows between the sub-district and Mozambique. In 2007 there was a modest net in-flow of people,
with 118 people entering from Mozambique and 43 moving back to Mozambique.

an income through their pensions. They are able to influence household decisions about the allocation of
resources and ensure better food security and increased access to schooling, especially for girls. In fact, older
women generally provide crucial support – financial, physical and emotional - to adult children who have
become ill and to fostered and orphaned grandchildren [26]. These obligations are
likely to increase as a result of migration and the impact of HIV/AIDS.
As mentioned earlier, child support grants – for children up to the age of 14 years –
have resulted in improved child nutritional status [9]. However, there are many
barriers that prevent access to these grants: only a third of South African families
living in Agincourt in the lowest socioeconomic stratum had applied at the time of
the research [27]. It is the less-impoverished families that make better use of
these grants. Barriers to access include lack of the necessary documentation,
unmanageable distance to offices and a low educational level of the household
head.
IMPLICATIONS FOR POLICY AND PRACTICE
The findings of the Agincourt research site throw light on the experience of a poor, rural population. This sort of
community is seldom well-researched. The findings are invaluable for understanding priorities for policy and
practice locally, as well as in the region.
Respond to the health transition
The health system needs to improve its ability to respond not only to the usual conditions of poverty, such as
malnutrition and tuberculosis, but also the HIV/AIDS epidemic and increasing hypertension, obesity and
diabetes. Removing barriers to access is essential but
so, too, is improving the quality of care. Specific ‘A return to favourable mortality trends will require not

Allocate resources locally for migrants
Because of economic patterns established under apartheid, former homelands are bearing a heavy burden of
sickness and death. In these communities, there is a need to respond more effectively to the special needs of
highly mobile populations and their home communities.
Design health promotion strategies that respond to people’s underlying beliefs and norms
People are being deterred from accessing life-saving treatment – such as antiretrovirals and hypertensive drugs because they have beliefs that contradict scientific explanations. Health promotion strategies need to take this
into account and find ways of accommodating these beliefs to enhance access. This is critical for dealing with the
HIV/AIDS epidemic.
Box 3: Working with the community, service providers and local government to increase access
to child support grants
A special module of the 2002 Agincourt census update assessed household access to the
government child support grants which had been introduced in 1998. The research found high
levels of non-access, especially amongst the poorest households. In 2004, these findings, and an
analysis of the main barriers to access, were presented to the provincial and local Departments of
Home Affairs, Education and Social Security. This resulted in:
2-day mobile Home Affairs and Social Security campaigns in 20 villages, during which 8,000 people
applied for identity documents and birth certificates; 2 community workshops providing
information on services for orphans and vulnerable children; the special deployment of 6 child
support grant extension officers employed by Social Security; a partnership between the research
site, another Wits research unit, Home Affairs and the Mozambique Consulate in ongoing planning
to assist former Mozambican refugees who are stateless; and a partnership between the research
site, the local municipality and NGOs to form a multi-departmental district task team on orphans
and vulnerable children.
[adapted 4:14]
Exploit natural resources for household survival
Agincourt research has shown that natural food sources help to buffer impoverished households against shocks,
both through contributing to diets and providing an opportunity for generating income. Indeed, local vegetation
forms an important part of the diet of all households. It is important to improve the productivity of homestead
gardens and encourage the cultivation of wild herbs and traditional crops.
Recognize the role of older women
Research at Agincourt has shown that older women play an
important role in sustaining the family and improving both health
and gender equity. Intervention strategies need to build on this
role but also find ways to support the efforts of this sector of the
community.

THEME 1: Levels, trends and transitions
(Theme leader: Clark with Collinson)
Demographic and epidemiological changes taking place in rural populations need to be understood for health
and development planning at district, provincial and national levels. We need to identify the forces driving
population change in mortality, morbidity, fertility, migration and socio-economics. The HDSS updates annually
individual’s residence dynamics including dates of entering or leaving the population (births, deaths, in and outmigrations), pregnancy outcomes, maternity history, relationship to household head, links to parents, marital
status, identity document status and national identity number. Research clusters represent collaborations of
scientists who use the HDSS to compute and publish trends in mortality, fertility, migration, and socio-economic
status.

In 2009, modules included: asset status, food security, education and labour status.
THEME 2: Child health and development
(Theme leader: Kahn with Pettifor; Theme officer: R Twine)
In rural South Africa, morbidity, mortality and growth failure associated with undernutrition exist alongside
female obesity and emerging cardiovascular disease. By tackling proximal issues of infant growth and nutrition,
and social/emotional development, we aim to impact more distal outcomes including cognitive development,
educational attainment, HIV infection, adult vascular risk and economic productivity.
Project Ntshembo: Improving the health and nutrition of adolescents and their infants to reduce the
intergenerational risk of metabolic disease
Collaboration with Birth-to-Twenty, Oxford and Cambridge Univs, UK; Umeå Univ, Sweden, Univ of North Carolina,
Chapel Hill, USA
Project aims to promote adolescent health as a critical pathway to improve intrauterine and infant growth and
thereby interrupt the intergenerational transfer of metabolic disease and HIV/AIDS. This will be achieved by
innovative community-based interventions targeting female adolescents prior to and during pregnancy, and in
the postnatal period. In 2010, funds were obtained from the British MRC to conduct the baseline survey from
July to December 2011 and follow up assessments over 5 years. Pilot work in May/June 2011 focused on
physical activity, beliefs and practices regarding childbirth and the postpartum period, and the availability and
distribution of food vendors.
Child and adolescent growth studies
Collaboration with Birth-to-Twenty
Studies seek to document and understand the double burden of undernutrition in children (particularly stunting)
and overweight/obesity in adolescents, particularly girls. One PhD was completed in 2010; another, on the
association of nutrition on body composition and metabolic disease risk, is ongoing.

Kulani Child Health and Resilience Project – evaluation of Soul Buddyz/SNOC
Collaboration with Soul City and Oxford Univ, UK
School-based, cluster-randomised trial to evaluate an established school-based intervention by an NGO, Soul
City, to provide emotional/social support to pupils 10-12 years and enhance their ability to cope and learn in an
environment of chronic adversity. Baseline study in 2009 examined rates of anxiety, depression and posttraumatic stress disorder, and environmental factors (parental death or migration, poverty) associated with
these symptoms. During 2010 there was ongoing monitoring of NGO intervention and the end-of-intervention
survey took place in October 2010. Data entry is almost complete. Analysis of baseline data has commenced,
and analysis of qualitative data on school management systems is complete.
SARI/ROTA - Severe Acute Respiratory Infection (SARI) and Rotavirus diarrhoea surveillance
Collaboration with NICD and the Respiratory and Meningeal Pathogens Research Unit, Wits
Aims to describe trends in numbers of SARI and diarrhoeal cases at 4 sentinel surveillance sites. Data will inform
health policy on SARI and diarrhoeal disease management, prevention and control, and assist in planning for
future influenza pandemics. Project will contribute to assessment of influenza, pneumococcal conjugate and
rotavirus vaccine strategies, reflecting on recent introduction of rotavirus & pneumococcal vaccines into the
national Expanded Programme on Immunisation. Surveillance system in two district hospitals in Bushbuckridge
(and other sites in South Africa) was set up in 2009 and data collection continues.
PCV - Pneumococcal Conjugate Vaccine Introduction
Collaboration with Respiratory and Meningeal Pathogens Research Unit, Wits
Study to examine the effect of pneumococcal conjugate vaccine immunization upon nasopharyngeal ecology of
Streptococcus pneumonia in vaccinated and non-vaccinated individuals at household level. In 2009,
nasopharyngeal swabs were taken, and questionnaires completed, in 600 households. There was no fieldwork in
2010, but there is a further survey currently underway.
Conditional Cash Transfer Study and Community Mobilisation (Swa Koteka)
Collaboration with University of North Carolina, USA, University of San Francisco, USA and Wits Reproductive Health and
HIV Institute
Study to determine effects of a multi-level HIV prevention intervention to jointly address structural and social
factors contributing to young women’s increased vulnerability to HIV, through providing cash transfers to
families of young women conditional on her attending school. Goal is to reduce young women’s HIV risk by
keeping her in school through improving her family’s economic resources. This intervention will be
complemented by a community-level mobilization intervention, One Man Can run by Sonke Gender Justice
focused on young men. Currently 1932 of the required population sample of 2660 HIV –ve young woman has
been recruited.
THEME 3: Adult health and wellbeing

to provide insight into management of a non-infectious chronic illness that spans all age groups. In 2010, three
data collection rounds were completed to identify new cases. There is close interaction with health services in
the study area with nurses providing information on patients’ clinic attendance. Study participants/patient
satisfaction is high since they are receiving improved health care including surgery for a brain tumour with
consequent health and social improvements. One MSc dissertation will be submitted in Feb 2011.
Cost evaluation of epilepsy treatment is part of PRICELESS study. In 2010, data entry was completed and data
cleaning commenced, 5 potential publications were identified and 1 PhD is to be nested in the work.
Health and wellbeing of ageing populations in Africa and Asia
Collaboration with INDEPTH sites, WHO, Umeå Univ, Sweden, Harvard and Colorado Univs, USA
Under Agincourt leadership, eight INDEPTH sites2 applied a short version of the WHO-SAGE3 instrument,
adapted to routine surveillance, to adults 50+ to assess baseline measures of physical and cognitive function and
establish cohorts of older adults in African and Asian settings. Comparative work sets out to test hypotheses
including: Poor self-rated general health (SRGH) is associated with premature mortality, and Individual SRGH
correlates with household characteristics such as wealth, presence of labour migrants, and loss of a prime-age
adult. In 2010 analyses examining mortality outcomes were undertaken on the longitudinal dataset. During the
2010 census update a 2nd round of data collection on adult health and aging was undertaken.
Health Care Utilisation: A module on health care utilization of people 50 years and older was conducted during
the 2010 census update round. Data entry was completed; analysis will be undertaken in 2011 and data will be
compared with data from the SAGE Long survey in 2006.
THEME 4: HIV/AIDS and Chronic care
(Theme leader: Tollman with Gómez-Olivé)
Immediate and longer-run community impacts of HIV/AIDS cannot be overstated. Evaluation of HAART delivery
will support provincial and national efforts and provide evidence on delivery models, coverage and
individual/population impacts.
HIV/NCD prevalence study
Collaboration with Wits Public Health, Colorado and Washington Universities, USA
Study to measure HIV prevalence, biomarkers for non-communicable chronic diseases (mainly cardiovascular
and diabetes) using dried blood spots, physical measurements including blood pressure and anthropometry, and
lifestyle and sexual risk behaviours. Fieldwork commenced in Aug 2010 after community entry and training. An
on-site post-doctoral fellow is responsible for managing day-to-day fieldwork. The sample consists of 7,428
people aged 15 years and older from all villages in the study site. Data collection finished end-Junel. Laboratory
results were returned on a weekly basis and those who wanted their HIV result went to the health centre. Blood
pressure, cholesterol and glucose results were given at the household with referral to nearest health facility for
all abnormal results. Funds will be sought for a further round of HIV and NCD testing and for conducting the
cBED assay. Results of this study will be available at the end of 2011.

Chronic care
A major effort addressing weaknesses in chronic care systems – and emphasizing commonalities in management
of both chronic infectious and non-communicable diseases – is planned. Research will be facilitated by the clinicHDSS link.
1. A partnership with the National Department of Health Chronic Disease Directorate has been established to
develop, implement and test an integrated chronic disease package at primary care level. In 2010 meetings
were held in the Mpumalanga Dept of Health and the Agincourt Health Centre, with follow-up discussions in
Johannesburg in January 2011.
2. Cost evaluation of epilepsy treatment will be conducted under the PRICELESS initiative.
THEME 5: Household response to shocks and stresses
(Theme leader: Collinson with W Twine)
Rural households remain under pressure. Sudden shocks, whether job loss or death of a breadwinner, can
destabilise households; similarly, protracted stresses such as drought or chronic illness can undermine coping
capacity and livelihoods. Key to understanding how to improve health and social development is to examine
the strategies employed by households to gain livelihoods and cope with shocks and stresses. The sustainable
livelihoods framework has been used in this theme with four productive research clusters:
The Natural Environment, Vulnerability and Resilience
Collaboration with APES, Wits and Colorado University, USA
Previous work showed that food security is threatened by adult mortality. We examine (i) how natural resources
are used to offset adversity, (ii) influence of climate change on environment (temperature, humidity, rainfall
monitoring introduced). In 2010 an NRF-funded project undertook the baseline of a cohort study of 600
households within the HDSS to examine household livelihood strategies and outcomes.
Social Connection, Vulnerability and Resilience
Collaboration with Maryland, Missouri, Colorado and Brown University, USA
The life-cycle of households are changing due to changing migration patterns and increasing mortality of prime
age adults. Qualitative studies are triangulated with surveillance-based analyses to investigate changing
household structure and composition. Changing social roles of fathers, mothers and older adults are examined
as well as the importance of links to social networks beyond the household. With NIH funds, we examine the
measurement of social connections (type, number and qualities of people’s relationships) through analyses of
ethnographic and HDSS data.
Migration, Livelihoods and Health
Collaboration with Brown University, Wits Demography and Population studies and INDEPTH
Migration brings risks and gains to health and wellbeing, affecting both the migrant and those who remain. The
HDSS has highlighted high levels of temporary migration which are increasing for younger women. Outcomes for
children’s health and household poverty are key research areas. Collinson was lead editor of a 2009 peerreviewed volume involving INDEPTH multi-country work; a second phase is underway. Grants awarded in 2010:
(i) Center for AIDS Research (CFAR), USA, for work on migration, HIV and socioeconomic change in South Africa;
(ii) Economic & Social Research Council (ESRC), UK, to assess impact of internal labour migration on patterns of
intergenerational support and the health and well-being of children and older people in China and South Africa.

Socio-economic dynamics
Collaboration with Washington University, USA; School of Accountancy, Wits
The HDSS meticulously tracks socio-economic status of households and uses this data to examine the dynamics
of household poverty and its relations to migration and other household livelihood strategies.
CONCLUSION
In the words of Professor Fred Binka, Executive Director of INDEPTH Network in Accra,
“Never before has the need for demographic and health data been so urgent in Africa. The emergence and reemergence of infectious diseases such as HIV/AIDS, malaria and tuberculosis, coupled with the rapid transition to
non-communicable diseases, is transforming African population and household structures in unprecedented
ways. Unfortunately, for millions of people living in the world’s most impoverished settings, there is little or no
information on their lives. Demographic surveillance brings welcome relief to this data void.” [21:3]
