Disparities in service and access

[edit | edit source]

There is a significant disparity in access to health care and public health initiatives between developed countries and developing countries, as well as within developing countries. In developing countries, public health infrastructures are still forming. There may not be enough trained health workers, monetary resources or, in some cases, sufficient knowledge to provide even a basic level of medical care and disease prevention.[1][2] As a result, a large majority of disease and mortality in developing countries results from and contributes to extreme poverty. For example, many African governments spend less than US$10 per person per year on health care, while, in the United States, the federal government spent approximately US$4,500 per capita in 2000. However, expenditures on health care should not be confused with spending on public health. Public health measures may not generally be considered "health care" in the strictest sense. For example, mandating the use of seat belts in cars can save countless lives and contribute to the health of a population, but typically money spent enforcing this rule would not count as money spent on health care.

Large parts of the world remained plagued by largely preventable or treatable infectious diseases. In addition to this however, many developing countries are also experiencing an epidemiological shift and polarization in which populations are now experiencing more of the effects of chronic diseases as life expectancy increases, the poorer communities being heavily affected by both chronic and infectious diseases.[2] Another major public health concern in the developing world is poor maternal and child health, exacerbated by malnutrition and poverty. The WHO reports that a lack of exclusive breastfeeding during the first six months of life contributes to over a million avoidable child deaths each year.[5] Intermittent preventive therapy aimed at treating and preventing malaria episodes among pregnant women and young children is one public health measure in endemic countries.

Since the 1980s, the growing field of population health has broadened the focus of public health from individual behaviors and risk factors to population-level issues such as inequality, poverty, and education. Modern public health is often concerned with addressing determinants of health across a population. There is a recognition that health is affected by many factors including class, race, income, educational status, region of residence, and social relationships; these are known as "social determinants of health". The upstream drivers such as environment, education, employment, income, food security, housing, social inclusion and many others effect the distribution of health between and within populations and are often shaped by policy.[6] A social gradient in health runs through society. The poorest generally have the worst health, but even the middle classes will generally have worse health outcomes than those of a higher social level.[7] The new public health advocates for population-based policies that improve health in an equitable manner.

The health sector is one of Europe's most labor-intensive industries. In late 2020, it accounted for more than 21 million employment in the European Union when combined with social work. According to the WHO, several countries began the COVID-19 pandemic with insufficient health and care professionals, inappropriate skill mixtures, and unequal geographical distributions. These issues were worsened by the pandemic, reiterating the importance of public health.[8] In the United States, a history of underinvestment in public health undermined the public health workforce and support for population health, long before the pandemic added to stress, mental distress, job dissatisfaction, and accelerated departures among public health workers.[9]

Health aid in developing countries

Health aid to developing countries is an important source of public health funding for many developing countries.[11] Health aid to developing countries has shown a significant increase after World War II as concerns over the spread of disease as a result of globalization increased and the HIV/AIDS epidemic in sub-Saharan Africa surfaced.[12][13] From 1990 to 2010, total health aid from developed countries increased from 5.5 billion to 26.87 billion with wealthy countries continuously donating billions of dollars every year with the goal of improving population health.[13] Some efforts, however, receive a significantly larger proportion of funds such as HIV which received an increase in funds of over $6 billion between 2000 and 2010 which was more than twice the increase seen in any other sector during those years.[11] Health aid has seen an expansion through multiple channels including private philanthropy, non-governmental organizations, private foundations such as the Rockefeller Foundation or the Bill & Melinda Gates Foundation, bilateral donors, and multilateral donors such as the World Bank or UNICEF.[13] The result has been a sharp rise in uncoordinated and fragmented funding of an ever-increasing number of initiatives and projects. To promote better strategic cooperation and coordination between partners, particularly among bilateral development agencies and funding organizations, the Swedish International Development Cooperation Agency (Sida) spearheaded the establishment of ESSENCE,[14] an initiative to facilitate dialogue between donors/funders, allowing them to identify synergies. ESSENCE brings together a wide range of funding agencies to coordinate funding efforts.

In 2009 health aid from the OECD amounted to $12.47 billion which amounted to 11.4% of its total bilateral aid.[15] In 2009, Multilateral donors were found to spend 15.3% of their total aid on bettering public healthcare.[15]

International health aid debates

[edit | edit source]

Debates exist questioning the efficacy of international health aid. Supporters of aid claim that health aid from wealthy countries is necessary in order for developing countries to escape the poverty trap. Opponents of health aid claim that international health aid actually disrupts developing countries' course of development, causes dependence on aid, and in many cases the aid fails to reach its recipients.[11] For example, recently, health aid was funneled towards initiatives such as financing new technologies like antiretroviral medication, insecticide-treated mosquito nets, and new vaccines. The positive impacts of these initiatives can be seen in the eradication of smallpox and polio; however, critics claim that misuse or misplacement of funds may cause many of these efforts to never come into achievement.[11]

Economic modeling based on the Institute for Health Metrics and Evaluation and the World Health Organization has shown a link between international health aid in developing countries and a reduction in adult mortality rates.[13] However, a 2014–2016 study suggests that a potential confounding variable for this outcome is the possibility that aid was directed at countries once they were already on track for improvement.[11] That same study, however, also suggests that 1 billion dollars in health aid was associated with 364,000 fewer deaths occurring between ages 0 and 5 in 2011.[11]

Sustainable development goals for 2030

[edit | edit source]

To address current and future challenges in addressing health issues in the world, the United Nations have developed the Sustainable Development Goals to be completed by 2030.[16] These goals in their entirety encompass the entire spectrum of development across nations, however Goals 1–6 directly address health disparities, primarily in developing countries.[17] These six goals address key issues in global public health, poverty, hunger and food security, health, education, gender equality and women's empowerment, and water and sanitation.[17] Public health officials can use these goals to set their own agenda and plan for smaller scale initiatives for their organizations. These goals are designed to lessen the burden of disease and inequality faced by developing countries and lead to a healthier future. The links between the various sustainable development goals and public health are numerous and well established.[18][19]
