Obesity is a medical condition, sometimes considered a disease, in which excess body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis.
The value of life is an economic value used to quantify the benefit of avoiding a fatality. It is also referred to as the cost of life, value of preventing a fatality (VPF), implied cost of averting a fatality (ICAF), and value of a statistical life (VSL). In social and political sciences, it is the marginal cost of death prevention in a certain class of circumstances. In many studies the value also includes the quality of life, the expected life time remaining, as well as the earning potential of a given person especially for an after-the-fact payment in a wrongful death claim lawsuit.
Health economics is a branch of economics concerned with issues related to efficiency, effectiveness, value and behavior in the production and consumption of health and healthcare. Health economics is important in determining how to improve health outcomes and lifestyle patterns through interactions between individuals, healthcare providers and clinical settings. In broad terms, health economists study the functioning of healthcare systems and health-affecting behaviors such as smoking, diabetes, and obesity.
Preventive healthcare, or prophylaxis, is the application of healthcare measures to prevent diseases. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes that begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention.

Diseases of poverty are diseases that are more prevalent in low-income populations. They include infectious diseases, as well as diseases related to malnutrition and poor health behaviour. Poverty is one of the major social determinants of health. The World Health Report (2002) states that diseases of poverty account for 45% of the disease burden in the countries with high poverty rate which are preventable or treatable with existing interventions. Diseases of poverty are often co-morbid and ubiquitous with malnutrition. Poverty increases the chances of having these diseases as the deprivation of shelter, safe drinking water, nutritious food, sanitation, and access to health services contributes towards poor health behaviour. At the same time, these diseases act as a barrier for economic growth to affected people and families caring for them which in turn results into increased poverty in the community. These diseases produced in part by poverty are in contrast to diseases of affluence, which are diseases thought to be a result of increasing wealth in a society.
Pharmacoeconomics refers to the scientific discipline that compares the value of one pharmaceutical drug or drug therapy to another. It is a sub-discipline of health economics. A pharmacoeconomic study evaluates the cost and effects of a pharmaceutical product. Pharmacoeconomic studies serve to guide optimal healthcare resource allocation, in a standardized and scientifically grounded manner.
Health policy can be defined as the "decisions, plans, and actions that are undertaken to achieve specific healthcare goals within a society". According to the World Health Organization, an explicit health policy can achieve several things: it defines a vision for the future; it outlines priorities and the expected roles of different groups; and it builds consensus and informs people.

A public health intervention is any effort or policy that attempts to improve mental and physical health on a population level. Public health interventions may be run by a variety of organizations, including governmental health departments and non-governmental organizations (NGOs). Common types of interventions include screening programs, vaccination, food and water supplementation, and health promotion. Common issues that are the subject of public health interventions include obesity, drug, tobacco, and alcohol use, and the spread of infectious disease, e.g. HIV.
HIV/AIDS affects economic growth by reducing the availability of human capital. Without proper prevention, nutrition, health care and medicine that is available in developing countries, large numbers of people are developing AIDS.

Life expectancy in Nicaragua at birth was 72 years for men and 78 for women in 2016. While communicable diseases such as dengue, chikungunya, and Zika continue to persist as national health concerns, there is a rising public health threat of non-communicable diseases such as diabetes, cardiovascular disease, and cancer, which were diseases previously thought to be more relevant and problematic for more developed nations. Additionally, in the women's health sector, high rates of adolescent pregnancy and cervical cancer continue to persist as national concerns.
The economics of digitization is the field of economics that studies how digitization, digitalisation and digital transformation affects markets and how digital data can be used to study economics. Digitization is the process by which technology lowers the costs of storing, sharing, and analyzing data. This has changed how consumers behave, how industrial activity is organized, and how governments operate. The economics of digitization exists as a distinct field of economics for two reasons. First, new economic models are needed because many traditional assumptions about information no longer hold in a digitized world. Second, the new types of data generated by digitization require new methods for their analysis.
