Changing health profile: a double or triple burden of disease and injuries n n Changing health profile: a double or triple burden of disease and injuries n n n 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.

How to effectively address NCDs in SSA? How to effectively address NCDs in SSA?

Align health strategy with SSA’s future to make a stronger case for investing in Align health strategy with SSA’s future to make a stronger case for investing in health n n n 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 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 n There are four ways that this might be achieved: Ø Capitalize on links between conditions Ø Focus on common functions (prevention, treatment, care) rather than disease categories Ø Implement proven, cost-effective interventions Ø Capitalize on existing resources and capabilities

Capitalize on the inter-linkages between conditions and on their common determinants n Not much Capitalize on the inter-linkages between conditions and on their common determinants n 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. n n n 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

Maternal and child health has potential longterm consequences for NCDs n n n Poor Maternal and child health has potential longterm consequences for NCDs n n n 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 n Growing cross-fertilization Focus on common functions (prevention, treatment, care) rather than disease categories n Growing cross-fertilization of care approaches between CDs and NCDs: Ø 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. Ø 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. Ø 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 n Leveraging the resources, experience, and models of Capitalize on existing resources and capabilities n 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 n Redesigning the delivery of services around multidisciplinary teams to facilitate task-shifting among personnel and bringing care closer to the patient n Common procurement and supply lines for essential drugs, scaling up the use of new technologies, such as mobile phones and integrated health information systems n Linking health spending decisions to adoption of clinical guidelines for service provision to encourage coordination of care and improve the quality of services

Implement proven cost-effective interventions Effective tobacco control requires multisectoral policies and actions n On Implement proven cost-effective interventions Effective tobacco control requires multisectoral policies and actions n 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. ” n 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. n 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.

A new role for Global Health Diplomacy Collaboration and sharing of knowledge and experiences A new role for Global Health Diplomacy Collaboration and sharing of knowledge and experiences among countries n n n 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 Source: Frenk, J.

Take-away Messages n n n Improved health and social development are critical investments for Take-away Messages n n n 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
