The World Health Organization (WHO) is a specialized agency of the United Nations responsible for global public health. It is headquartered in Geneva, Switzerland, and has six regional offices and 150 field offices worldwide. Only sovereign states can participate, and it is the largest intergovernmental health organization at the international level.
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis.
The World Health Organization Framework Convention on Tobacco Control is a treaty adopted by the 56th World Health Assembly held in Geneva, Switzerland on 21 May 2003. It became the first World Health Organization treaty adopted under article 19 of the WHO constitution. The treaty came into force on 27 February 2005. It had been signed by 168 countries and is legally binding in 182 ratifying countries. There are currently 14 United Nations member states that are non-parties to the treaty.
In epidemiology, a risk factor or determinant is a variable associated with an increased risk of disease or infection.
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 affluence, previously called diseases of rich people, is a term sometimes given to selected diseases and other health conditions which are commonly thought to be a result of increasing wealth in a society. Also referred to as the "Western disease" paradigm, these diseases are in contrast to "diseases of poverty", which largely result from and contribute to human impoverishment. These diseases of affluence have vastly increased in prevalence since the end of World War II.
A healthy diet is a diet that maintains or improves overall health. A healthy diet provides the body with essential nutrition: fluid, macronutrients such as protein, micronutrients such as vitamins, and adequate fibre and food energy.
Global health is the health of populations in a worldwide context; it has been defined as "the area of study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide". Problems that transcend national borders or have a global political and economic impact are often emphasized. Thus, global health is about worldwide health improvement, reduction of disparities, and protection against global threats that disregard national borders, including the most common causes of human death and years of life lost from a global perspective.
In a 2018 study on 599,912 drinkers, a roughly linear association was found with alcohol consumption and a higher risk of stroke, coronary artery disease excluding myocardial infarction, heart failure, fatal hypertensive disease, and fatal aortic aneurysm, even for moderate drinkers. Alcohol abuse may also cause occupational cardiovascular disease. The American Heart Association states that people who are currently non-drinkers should not start drinking alcohol.
Alcohol has a number of effects on health. Short-term effects of alcohol consumption include intoxication and dehydration. Long-term effects of alcohol include changes in the metabolism of the liver and brain, with increased risk of several types of cancer and alcohol use disorder. Alcohol intoxication affects the brain, causing slurred speech, clumsiness, and delayed reflexes. There is an increased risk of developing an alcohol use disorder for teenagers while their brain is still developing. Adolescents who drink have a higher probability of injury including death.
The social determinants of health (SDOH) are the economic and social conditions that influence individual and group differences in health status. They are the health promoting factors found in one's living and working conditions, rather than individual risk factors that influence the risk or vulnerability for a disease or injury. The distribution of social determinants is often shaped by public policies that reflect prevailing political ideologies of the area.
Diseases of poverty, also known as poverty-related diseases, 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.
A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson's disease, autoimmune diseases, strokes, heart diseases, cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, and others. NCDs may be chronic or acute. Most are non-infectious, although there are some non-communicable infectious diseases, such as parasitic diseases in which the parasite's life cycle does not include direct host-to-host transmission.
Nutrition transition is the shift in dietary consumption and energy expenditure that coincides with economic, demographic, and epidemiological changes. Specifically the term is used for the transition of developing countries from traditional diets high in cereal and fiber to more Western-pattern diets high in sugars, fat, and animal-source food.
Health in Ethiopia has improved markedly since the early 2000s, with government leadership playing a key role in mobilizing resources and ensuring that they are used effectively. A central feature of the sector is the priority given to the Health Extension Programme, which delivers cost-effective basic services that enhance equity and provide care to millions of women, men and children. The development and delivery of the Health Extension Program, and its lasting success, is an example of how a low-income country can still improve access to health services with creativity and dedication.
The healthcare system in Turkey has improved in terms of health status especially after implementing the Health Transformation Program (HP) in 2003. "Health for All" was the slogan for this transformation, and HP aimed to provide and finance health care efficiently, effectively, and equitably. By covering most of the population, the General Health Insurance Scheme is financed by employers, employees, and government contributions through the Social Security Institution. Even though HP aimed to be equitable, after 18 years of implementation, there are still disparities between the regions in Turkey. These discrepancies can be seen in terms of infant mortality between rural and urban areas and different parts of the country, although these have been declining over the years. While the under-5 mortality rate in Western Marmara is 7.9, the under-5 mortality rate in Southeastern Asia is two times higher than Western Marmara, with the rate of 16.3 in 2021.
Preventable causes of death are causes of death related to risk factors which could have been avoided. The World Health Organization has traditionally classified death according to the primary type of disease or injury. However, causes of death may also be classified in terms of preventable risk factors—such as smoking, unhealthy diet, sexual behavior, and reckless driving—which contribute to a number of different diseases. Such risk factors are usually not recorded directly on death certificates, although they are acknowledged in medical reports.
The health effects of salt are the conditions associated with the consumption of either too much or too little salt. Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are chlorine ions. Salt is involved in regulating the water content of the body. Both sodium and chlorine ions are used for electrical signaling in the nervous system, among other biological roles.
Alcohol, sometimes referred to by the chemical name ethanol, is the second most consumed psychoactive drug globally behind caffeine. Alcohol is a central nervous system (CNS) depressant, decreasing electrical activity of neurons in the brain. The World Health Organization (WHO) classifies alcohol as a toxic, psychoactive, dependence-producing, and carcinogenic substance.
