Noncommunicable diseases (NCDs) pose a great threat to global health, as they contribute millions of deaths each year. Compared with infectious diseases, NCDs cannot be transmitted from one person to another but are often linked to lifestyle, habits, and even environmental factors. We hope to give you an overview to understand what really NCDs are, their global prevalence, what the risks factors are, and the role of health organizations on the global level in managing these chronic conditions. As we address the impact and burden of NCDs, we can also explore the strategies related to the prevention and control of these diseases—in the hope of lessening the burden of these pressing global health issues.

What are Noncommunicable Diseases (NCDs)?

Definition of Noncommunicable Diseases

A noncommunicable disease or NCD is a medical condition that is typically not due to infectious agents or microorganisms. NCDs are typically chronic in nature and it progresses slowly over time—and they have a prolonged duration, according to the World Health Organization (WHO). These conditions often arise due to a combination of factors, including:

• Genetic
• Physiological
• Environmental
• Behavioral

Types of Non-communicable Diseases

Noncommunicable diseases are categorized into several major types, which account for a substantial portion of the global disease burden. These include the following:

• Cardiovascular Diseases (CVDs): It is the most common noncommunicable disease type that affects the heart and blood vessels. It includes coronary artery disease (CAD), hypertension, heart failure, and stroke.
• Cancers: It includes different types of cancer—regardless of their location, such as the breast, colorectal, lung, and prostate.
• Chronic respiratory diseases: This includes asthma, chronic obstructive pulmonary disease (COPD), and occupational lung diseases, which affect a large portion of our workforce.
• Metabolism-related diseases: It includes diabetes mellitus, which is a disorder characterized by elevated blood glucose levels. This in turn leads to other serious complications, such as kidney failure, amputations, and blindness.

• Mental health disorders: Most of the time, these conditions are often overlooked. However, depression and anxiety also fall under NCDs because of their long-term and chronic nature that can impact on overall health.

Global Prevalence of NCDs

The staggering global prevalence of NCDs worldwide has been alarming health authorities. According to the WHO, NCDs are responsible for over 70% of deaths worldwide, which is about 41 million deaths per year. Of the 41 million deaths, 15 million of them die prematurely between the age of 30 and 69 years old. Further, it affects mostly the low- and middle-income countries, which accounts for an estimated 86% premature deaths. This global burden and prevalence of NCDs emphasize the crucial need for targeted interventions to address the alarming incidence of non communicable diseases and global health issues.

What are the Leading Causes of Death from NCDs?

About 17.9 million people die of cardiovascular diseases, which is the leading cause of NCD deaths per year. CVDs include conditions like stroke, heart failure, and heart attacks. These conditions are often the result of high cholesterol, high blood pressure, and other lifestyle factors like lack of exercise, smoking, and poor diet. The impact of these disorders go beyond mortality, which contributes to substantial morbidity that can reduce the quality of life for the global population.

Cardiovascular Disease and Its Impact

Cardiovascular diseases are the leading cause of death worldwide, affecting millions of mortalities annually. In the United States alone, CVD affects over 126 million people and the global prevalence is estimated to be more than 500 million cases. Its incidence increases with age, with the highest rates in older adults. It also represents 31% of all deaths, accounting to almost 18 million deaths per year. It is projected to increase to 22% by 2030 and overall have a global economic impact of about $860 billion in 2020 alone.

Respiratory Diseases: A Growing Concern

Respiratory diseases are one of the significant global health challenges, which leads to significant morbidity and mortality worldwide, including chronic obstructive pulmonary disease (COPD). This disease is among the most prevalent and has been contributing to significant mortality among respiratory conditions. COPD  has become one of the leading causes of death that affects millions, while requiring intensive care during acute exacerbations—leading to morbidity. Smoking is a known risk factor for respiratory diseases; but air pollution that’s rapidly rising contributes to the magnitude of the problem, especially in developing countries. Other factors include occupational hazards. The diagnosis and treatment of these diseases are costly and should be maintained lifelong, which can strain healthcare resources. On its own, COPD is responsible for more than 3 million deaths each year, according to the WHO, and is one of the leading causes of disability worldwide. If this isn’t a growing public health concern, maybe we should rethink what is.

Diabetes and Its Complications

Diabetes mellitus (DM, T2DM) is a lifelong metabolic disorder, which is characterized by increased blood sugar and disturbances in the balance of digesting and utilizing carbohydrates, proteins, and fat. It can lead to several complications that can add significant morbidity, including disorders affecting the eye (retinopathy), kidneys (nephropathy), nerves (neuropathy), heart disease, and even stroke. Complications arise due to activation of various signaling pathways due to the increased blood sugar levels. T2DM does not only affect blood sugar levels—leading to various physical complications—it also increases the risk for depression among patients, impacting employment and productivity, and is even linked to certain tumor growth. The increasing prevalence of diabetes and the complications pose a significant public health concern and economic burdens. However, the disease is highly treatable with proper management, lifestyle changes, and specific therapies—to prevent or delay the onset of these complications. 

What are the Risk Factors for NCDs?

NCDs are a major global public health issue, leading to about 70% of deaths worldwide. Known risk factors include the following:

• Tobacco use
• Sedentary lifestyle
• Unhealthy and unbalanced diets
• Excessive alcohol intake
• Air pollution

The risk factors mentioned are often related to a lot of things, such as economic transition, modern lifestyles, and rapid urbanization. 

Physical Inactivity and Its Role in NCDs

Physical inactivity or sedentary lifestyle is one of the major risk factors for NCDs, which accounts for about 6-10% of several chronic conditions worldwide, including coronary heart disease, T2DM, and cancers. About 1.6 million deaths yearly are attributed to physical inactivity and are associated with increased molecular stress, such as inflammation, DNA damage, and oxidative stress.

However, despite ranking as the fourth leading risk factor for NCD, it remains undervalued particularly in resource allocation and in policy making. Various factors, such as time constraints, lack of awareness, unhealthy dietary practices and choices, and even poverty, are identified to exacerbate the condition.

The Impact of Unhealthy Diets

Unhealthy diets—and lack of healthy choices—contribute to the burden of obesity and NCDs, which significantly increased global mortality and public health burden. Food availability is shaped by industry practices and heavily influenced by people’s dietary choices. Many countries around the world demonstrate inadequate dietary patterns described as high calorie, fat, sodium, and sugar content, combined with insufficient intake of fruit and vegetables. And, it is not just the urban areas that exhibit these patterns, the rural areas from various income levels have been practicing the same, which is why implementing policies and population-based interventions are important.

Tobacco Use and Alcohol Consumption

Tobacco (cigarette) use and excessive alcohol consumption are important global risk factors for NCDs. In one study, these factors account for about 13% of the total mortality with policies aligning with international recommendations to control the impact of these risk factors. Another study pointed out that women who smoked, used smokeless tobacco, or intake of alcohol had an increased risk of developing NCDs compared to non-smokers or those not consuming alcohol. A cross-sectional survey showed that more than 26% of men consumed alcohol and about 19% used tobacco, which strengthened the evidence pointing to tobacco and alcohol as risk factors for NCDs. These studies emphasize the need for a multidisciplinary approach—not just public health—and targeted interventions to combat the burden of increasing NCD prevalence.

How Can We Prevent and Control NCDs?

Effective prevention strategies and control of NCDs include implementing public health policies that adequately control the known risk factors, such as tobacco and alcohol consumption, minimizing unhealthy dietary components, and promoting consumption of healthy and balanced diets. Since NCDs may have occurred in early life, a life-course approach is important for its control and prevention. Since key modifiable risk factors have already been identified, such as tobacco use, unhealthy, and sedentary lifestyle, it is important to monitor this from childhood to adulthood.

Public health policies and strategies play a crucial role in preventing and controlling the alarming rise of NCDs by focusing on health promotion and education, risk reduction, and strengthening the health systems. Furthermore, the policies must specifically address the burden of NCD prevalence due to the aging population as well as its effect on health services. 

Action Plans for NCD Prevention

The WHO and many countries around the world have developed crucial action plans for the prevention and control of NCDs. For example in Pakistan, they have a National Action Plan that incorporates several policies, such as injury, road traffic, and occupational injury prevention into their comprehensive NCD prevention and control effort. In addition, they also integrated cancer prevention and control, putting emphasis on diet, physical activity, and diet as risk-cutting approaches.

Action plans should prioritize surveillance systems, correct implementation of legislation, strengthening and capacity building of health systems, and development of mechanisms for institutional implementation of NCD prevention and control. It should also put emphasis on the significance of having evidence-based prevention efforts that are sustainable towards betterment of healthcare services.

Role of Primary Health Care in NCD Control

Primary Health Care (PHC) plays a significant role in the prevention and control of NCDs particularly in developing countries. The services of PHC can be strengthened in order to address the alarming rise of NCD. In order to do this, we need to do capacity-building through training of healthcare workers—particularly in detection of high risk populations—continued supply of essential equipment for screening and medicines, and capacitance of the medical information systems for a more streamlined approach.

A comprehensive PHC approach focuses on the prevention and control of chronic diseases—with specific emphasis on promotion and education. This approach enhances implementation of healthcare strategies to achieve better health outcomes without increasing the costs. When NC interventions are integrated into PHC is considered as the most effective model for enhanced service delivery that’s sufficient and impactful.

Many countries can use PHC as a guiding framework for policy and strategy implementation in addressing NCDs especially in resource-limited settings. Through this, we can improve our capacity, do research particularly risk factor surveys, and create public awareness through educational campaigns. 

Strategies for Low- and Middle-Income Countries

NCDs pose a burden particularly in low- and middle-income countries requiring tailored strategies for its management and prevention. As advocated by WHO, effective strategies may include implementing “best buys” where communities utilize their health workers and taking advantage of mobile technology. In these low-resource settings, patients and healthcare workers can take advantage of self-management interventions, especially those using phone calls and SMS, to improve health outcomes—particularly in cases of heart failure, diabetes, and hypertension.

When it comes to large-scale prevention strategies, healthcare systems must implement comprehensive tobacco and alcohol control, minimize unhealthy food choices, promote healthy food intake, and advocate universal primary care systems. Key strategies may also include focusing on workforce training and development, proper financial allocation, and investment on infrastructure to increase healthcare access. These simple strategies may be a tall order but could help low-resource settings thrive in a fast-changing healthcare environment.

What is the Role of Global Health Organizations in NCD Management?

Global health organizations particularly the WHO play a vital role in the prevention and management of NCDs by establishing different mechanisms and initiatives. WHO developed the Global Coordination Mechanism (GCM) on NCDs in 2014. This initiative focuses on awareness, advocacy, and multisectoral approach. The global response to the alarming rise of NCDs that involve various partnerships and initiatives that require evaluation and high levels of coordination. The leadership of WHO in preventing and controlling NCD was further supported by the 2011 UN Political Declaration that led to the development of global action plans specifying targets in the year 2025. However, this global health effort to promote prevention of NCD as a priority has been criticized as a marketing opportunity, which overshadows other health problems in low-resource countries.

What Are the Economic and Social Impacts of NCDs?

The Burden of Noncommunicable Diseases

NCDs have become a major public health issue on a global magnitude, which poses a threat specifically for developing countries that will bear the brunt of the burden. The economic impact of NCD is very significant, with treatment costs that nearly doubles than what is being spent on other illnesses. It is of extreme value to embark on preventive strategies, catch the disease early, and control the risk factors so as to address this rising problem. Governments and healthcare systems must strengthen the strategies or establish one that can fully implement such population-based interventions, and promote multi-sectoral collaboration to enable the healthcare system to deal with NCD.

Impact on Universal Health Coverage

Achieving universal health coverage (UHC) and equity in health is significantly challenging particularly in matters of NCDs. UHC, in general, aims to offer constituents widely accessible, affordable, and complete primary healthcare packages. However, the alarming prevalence of NCDs has put a lot of strain to the healthcare system as well as the out-of-pocket expenditure of people, especially in developing countries.

Therefore, effective UHC implementation for NCD programs would first require the healthcare systems to be strengthened, proper budget allocation, and making essential medicines a priority in purchases—all of which can reduce the burden of the problem. The impact of NCD on UHC can even be seen in mature health systems in countries like Australia where the implementation challenges still exist, which includes establishing an episodic primary care and ensuring inequitable distribution of health services.

Long-term Consequences on Global Health

NCDs pose a significant long-term impact and consequences on Global Health. It affects labor, man-power, savings, and investment, which hinder both economic development and growth. The concept of DOHaD (developmental origins of health and disease) states that early life conditions influence whether NCDs develop, which means preventive strategies must start during childhood—to minimize the long-term consequences on global health.
