Noncommunicable Diseases by Team Get It



Noncommunicable Diseases

Noncommunicable diseases (NCDs) are the leading cause of death worldwide in low, middle, and high income countries (http://www.economist.com/node/21556393). NCDs include cardiovascular disease, diabetes, cancer, and mental disorders. As a result of social detriments of health and globalization, present and future rates of NCDs are on the rise which poses concerns for global health, healthcare workers, and challenges for health care systems—particularly surrounding costs and financing. To combat the growing concern on NCDs, WHO (http://www.who.int/mediacentre/factsheets/fs355/en/) has begun Global Action Plan (http://www.who.int/gho/ncd/en/index.html) which offers nine specific target goals to prevent, reduce, and address response to NCDs—these targets focus on controllable elements such as diet, limiting alcohol and tobacco use, and increasing physical activity as well as additional elements such as coverage of health care services, and reducing premature mortality.








With the current shift in awareness towards NCDs, The NCD Alliance (http://ncdalliance.org/) states: “The omission of NCD indicators in the MDGs has been a barrier to securing donor funding for NCDs”. Additionally, GBCHealth (http://www.gbchealth.org/) a coalition whose stated mission is: “to leverage the power and resources of the business community for positive impact on global health challenges”, is working with partner organizations to address the stated target of a 25 percent reduction in premature mortality from non-communicable diseases by 2025. The partner organization, Medtronic Philanthropy (http://www.gbchealth.org/news-article/778-medtronic_philanthropy_seeks_global_partners_to_combat_non-communicable_diseases/), is seeking a five year initiative increasing access to care for chronic disease, with a focus in cardiovascular disease and diabetes. Other organizations rising to challenge, are ones such as NCD Free,  (http://ncdfree.org/) a self-stated global social movement against NCDs, comprised of a core group of young professionals, backed by supporting and partner organizations from around the globe. Through global events, advocacy films, on the ground community work, and more, NCD Free is bringing non-communicable disease education and advocacy into the spotlight.




In Zambia, for example, MkondoLungu, Deputy Speaker of the National Assembly, urged both corporate and private sectors to join the government’s efforts to fight cardiovascular disease, “the highest silent killer in Zambia.” (http://allafrica.com/stories/201311140463.html) According to WHO (http://www.who.int/en/), 33% of total mortality rates in Kenya in 2007 were due to NCDs. In response to their problem, Kenya created a National Strategic Plan on NCDs, (http://www.times-publications.com/non-communicable.htm) in which “the Ministry of Health has already achieved much, including: setting up legislative and legal frameworks; developing policy guidelines; and developing clinical and training guidelines.” During a Non-Communicable Disease Synergies Network (http://www.ghdonline.org/ncd-synergies-kigali2013/) conference held last July, Kenya was among the countries pointed out for effectively addressing this global epidemic. Niger has also created a National Strategic Plan to prevent and control NCDs by “strengthening the control of NCDs; strengthening governance and leadership in the prevention and control of NCDs; developing mechanisms for financing NCDs control, and promoting research on NCDs.”

Despite the current efforts in building awareness and working to combat the prevalence of NCDs, social determinants of health remain a huge factor impacting the prevalence of NCDs. Both NCD risk factors and mortality from NCDs are higher in low and middle income countries—within countries people are affected by NCDs disproportionately along the social gradient. In addition, low and middle income countries are unlikely to have the economic ability to meet the double health, economic, and social burdens of CDs and NCDs (http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2813%2960063-X/fulltext).  

Low-income people are disproportionately exposed to NCD risk factors of excessive tobacco and alcohol consumption, lack of access to nutritious foods, insufficient physical activity, all of which lead to raised blood pressure, overweight/obesity, hyperglycemia, and hyperlipidemia. In addition to these risk factors, people in low-income countries face added risks, “including use of biomass fuels and coal for cooking and heating, which are risk factors for chronic obstructive pulmonary disease and lung cancer; fetal and early childhood under-nutrition,” these are also linked to cardiovascular and metabolic diseases in the adult years of life along with “infections that can lead to rheumatic heart disease, cardiomyopathy, heart failure, and cancers of the cervix, liver, stomach, and other sites.” (http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2812%2961851-0/fulltext).

As the epidemiological shift from communicable diseases (CDs) to NCDs occurs, the global health community will have to augment their focus on prevention and care to include long-term treatment in order to adequately address the double-burden of CDs and NCDs. As we know, upstream factors such as public policies are dominant forces that influence health outcomes. Forming public policies that ensure access to healthy home environments, work environments, community environments, foods, and high-quality healthcare are essential to decreasing the prevalence and impacts of CDs and NCDs. Throughout history we have seen that once countries become more developed they go through a period known as the epidemiologic transition. This transition can be described as the changing patterns of population age distributions, mortality, fertility, life expectancy, and causes of death (http://ajl.sagepub.com/content/3/1_suppl/19S.full.pdf+html). This is saying that with the advancement of medicine people are now living longer than ever before—with longevity comes the problem of having to treat chronic diseases.

Countries such as the US and Canada completed this transition in the 1950’s and countries such as Brazil, Columbia and Costa Rica have been going through this transition since the 1980’s and 1990’s (http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2813%2961343-4/fulltext) One of the issues this transition brings with it is the increasing cost that caring for these diseases will bring on our economy . A 2011 study published by The Harvard University Public Health Department estimated the total economic cost of NCDs from the year 2011-2030 could reach a staggering $47 trillion (http://www.weforum.org/EconomicsOfNCD). This will affect everyone and not only the low-middle income countries (see table1). One thing I would like to point out is that these figures are estimates and not definite; we can do many things to address these issues, some of which are already in place, such as building awareness, collaborative global efforts, and providing education on steps individuals can make to improve their health such as the importance of nutrition.

The anticipated economic burden of NCDs, 2011-2030 (trillions of US$ 2010)1



Connections between the cause of chronic diseases and nutrition are well-supported http://www.mcspotlight.org/media/reports/who_rep.html. What have become known as the ‘Big-4’ (http://www.ncdchild.org/NCDs/Specific-NCDs) of the non-communicable disease list - Cardiovascular Diseases, Cancers, Diabetes, and Chronic Lung Diseases-have all been linked (http://ajcn.nutrition.org/content/84/2/289.long) to the increasingly poor food system. As a result of this, the Big-4 are now coined nutrition-related non-communicable diseases (NR-NCDs). “The magnitude of the impact of diet on disease risk and the potential for prevention have been highlighted by recent studies” (http://www.cpc.unc.edu/projects/nutrans/research/bellagio/papers/PHNPekkaFinland.pdf). As the drive for, and evolution into, the globalization of our world is becoming more and more realized, it has become all too obvious that changes in diet and nutrition are major factors in the global disease transition from communicable to non-communicable.

                   The NR-NCDs were at one time referred to as diseases of the affluent; however, over the last couple decades this has ceased to be true. NR-NCDs are no longer considered diseases of the affluent in higher-income countries, and are increasingly growing in lower- and middle-income countries. Along with the spread of development and globalization populations are enticed and in some cases forced from their traditional food cultivation, preparation, and cuisine to a “diet that is high in saturated fat, sugar and refined foods and low in fiber” (http://www.cpc.unc.edu/projects/nutrans/publications/PHNPopkinOverview.pdf). This diet is also known as the Western diet (http://ajcn.nutrition.org/content/). A diet that is tied to the land of dreams fulfilled and all things thought to be achievable, but with the price tag of cardiovascular diseases, cancers, diabetes, and chronic lung diseases. 

In conclusion, there are many elements in play that are aiding in the rise and prevalence of NCDs such as social detriments of health, nutrition, epidemiologic transition, a lack of access to health care services, and cost. Currently, NCDs kill more than 36 million people a year with a concentration of 80% of NCDs in low and middle income countries (http://www.who.int/mediacentre/factsheets/fs355/en/). Additionally, these rates are expected to increase in the next 10-20 years. While there are links to the causes of NCDs the causes of the causes are preventable and avoidable. The efforts that are in place focus greatly on the causes but unless the entirety of the issue is addresses which includes acknowledging the causes of the causes and making changes to these global health will continue to be greatly influenced by NCDs.
