Changing health profile: a double or triple
burden of disease and injuries
While progress has been achieved in reducing premature
mortality from communicable, maternal, neonatal, and
nutritional causes, these conditions still account for 3 out of 4
premature deaths.
At the same time, deaths from NCDs and road traffic injuries
have emerged as leading causes of years of life lost.
NCDs are expected to become the leading cause of ill health
and death by 2030, influenced by rapid urbanization, change
in diet, change in risk factors from poverty to behavior, and
improvements in the control of CDs that increase life
expectancy.
NCDs and RTIs already account for almost a
third of deaths in the region

How to effectively address NCDs in SSA?
Align health strategy with SSA’s future to make
a stronger case for investing in health
To improve competitiveness and employment: a healthy and
skilled workforce is critical.
To reduce vulnerability and increase resilience among the
population and in society: universal health coverage, both
financial protection and access to quality services, needed to
deal with cumulative effects of health shocks.
Domestic social spending needs to be increased, particularly
in mineral-rich countries, in tandem with building institutions
and systems and drawing on the contributions of multiple
sectors, to generate good health outcomes.
Potential risks of setting up yet another vertical program in
resource-constrained countries need to be acknowledged and
overcome, with integration and resource-sharing where feasible
There are four ways that this might be achieved:
Capitalize on links between conditions
Focus on common functions (prevention, treatment, care)
rather than disease categories
Implement proven, cost-effective interventions
Capitalize on existing resources and capabilities
Capitalize on the inter-linkages between
conditions and on their common determinants
Not much attention has been paid to the extent to which CDs
contribute to the NCD burden and to the potential common
intervention strategies in SSA.
Shared underlying social conditions: poverty, poor nutrition
Co-morbidities with both CDs and NCDs co-existing in the
same individual
Presence of one condition increases risk or impact of the other
e.g. smoking increases risk TB and impacts on HIV progression
Treatment of one condition increases risk of another e.g. ART
for HIV increases metabolic syndrome
Presence of one condition can be barrier e.g. stigma of HIV may
impede participation in health promotion opportunities
A third of cancers in Africa are related to infection,
and other risk factors are shared with NCDs

Maternal and child health has potential longterm consequences for NCDs
Poor maternal nutrition before and during pregnancy together
with smoking during pregnancy contributes to poor
intrauterine growth, resulting in low birth weight, which in
turn predisposes infant to metabolic disorders and NCD risk
in later life.
Gestational obesity is a strong predictor of future health, both
of the mother, who may develop diabetes and CVD later in
life, and the child, who also becomes at risk.
Problem is compounded by poverty and HIV/AIDS and TB:
e.g., low birth weight and malnutrition are more frequent in
HIV-infected children.
Focus on common functions (prevention,
treatment, care) rather than disease categories
Growing cross-fertilization of care approaches between CDs and NCDs:
Care models from HIV/AIDS and TB are being extended/adapted for
other chronic conditions and co-morbidities; e.g., DOTS for TB for
management of diabetes in Malawi.
Models already exist for collaboration with TB control programs for
syndromic guidelines in primary care to also benefit patients with noninfectious respiratory diseases such as asthma.
Chronic care models more frequently used for NCDs are also being
applied to cover infectious chronic diseases: e.g., to integrate and
improve quality of care for HIV, hypertension and diabetes are
underway in Uganda, Tanzania, and South Africa.
Capitalize on existing resources and capabilities
Leveraging the resources, experience, and models of existing programs,
such as HIV/AIDS, could benefit management of other chronic conditions
as part of integrated delivery systems
Redesigning the delivery of services around multidisciplinary teams to
facilitate task-shifting among personnel and bringing care closer to the
patient
Common procurement and supply lines for essential drugs, scaling up the
use of new technologies, such as mobile phones and integrated health
information systems
Linking health spending decisions to adoption of clinical guidelines for
service provision to encourage coordination of care and improve the
quality of services

district levels relevant for other chronic conditions

Integrating HIV/AIDS and cervical cancer
control: a promising high-impact entry point
High incidence and mortality from cervical cancer
Minimal cervical cancer screening services contribute to
patients being diagnosed at advanced stages of diseases
HIV-positive women are 4-5 times more likely to develop
cervical cancer
Some common underlying determinants e.g., sexually
transmitted infections; gender violence; links with alcohol
Potential for integrated solutions e.g., sexual health
promotion; cervical screening integrated into existing service
delivery platforms
Incidence of cervical cancer is highest in Eastern, Western
and Southern African regions – and a high proportion die

Scaling up from demonstration project to 5 regions across
the country
HPV vaccination to be introduced, beginning with a pilot
in Gaborone, targeting school age girls
Robust M&E in place to measure results and impact
Implement proven cost-effective interventions
Effective tobacco control requires multisectoral policies and actions
On June 3-5, 2012, the World Bank, with Ministry of Finance of
Botswana, Bloomberg/Gates Foundations, WHO and SADC, convened
in Gaborone high-level forum “The Economics of Tobacco Control:
Taxation and Illicit Trade.”
Delegations from Ministries of Finance, Trade, and Health of 14
SADC member countries and global and regional experts initiated
dialogue on effective design and administration of excise taxes on
tobacco to promote public health and share knowledge on causes and
extent of illicit trade of tobacco and strategies to control it.
A Community of Practice in 14 SADC member countries is now
evolving under World Bank coordination with other development
partners and funding from Bloomberg/Gates Foundations.
The 2011-2020 UN Decade of Action on
Road Safety: an entry point to deal with injuries
Five categories or "pillars" of activities:
building road safety management capacity
improving the safety of road infrastructure and broader transport
networks
further developing the safety of vehicles
enhancing the behavior of road users
improving post-crash care
The World Bank, working together with WHO and other
development partners, plays a key role in supporting global
effort
Countries that have successfully reduced RTIs have
adopted a safe systems approach
Elements are already in place in some African countries but strengthening of
institution and governance capacity is needed for better coordination of sectors

A new role for Global Health Diplomacy
Collaboration and sharing of knowledge and experiences among countries
A move away from “foreign health” /“domestic health” dichotomy
towards “global health "concept
Interdependence of health of populations (e.g., linkage of health
problems with production, trade, and travel)
Global transfer of health risks (e.g., tobacco trade, poor and
unhealthy diets and “globesity”, environmental risks)
Global transfer of opportunities (e.g., translation of knowledge into
new technologies, social action, evidence for policy)
Developing partnerships between countries (e.g., South-to-South
exchanges) to share knowledge, experience, and good practices
Adapting international good practices, strategic support, and
institutional capacity building to turn evidence into action

Take-away Messages
Improved health and social development are critical
investments for social transformation and sustained growth in
SSA as they pave the road to accelerated poverty reduction
and shared prosperity
Rather than concentrating on a few diseases, governments and
international agencies should prioritize building health
systems that offer universal financial protection, along with
improved access to and the use of quality services
An effective response also needs multisectoral policies and
actions for dealing with disease-related risk factors and their
social, economic, and environmental determinants
The importance of health in a society
“When health is absent, wisdom cannot reveal
itself, art cannot become manifest, strength
cannot fight, wealth becomes useless, and
intelligence cannot be applied”.
