Health has a variety of definitions, which have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders.
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. Specifically, it is "a deficiency, excess, or imbalance of energy, protein and other nutrients" which adversely affects the body's tissues and form. Malnutrition is not receiving the correct amount of nutrition. Malnutrition is increasing in children under the age of five due to providers who cannot afford or do not have access to adequate nutrition.
The American Heart Association (AHA) is a nonprofit organization in the United States that funds cardiovascular medical research, educates consumers on healthy living and fosters appropriate cardiac care in an effort to reduce disability and deaths caused by cardiovascular disease and stroke. They are known for publishing guidelines on cardiovascular disease and prevention, standards on basic life support, advanced cardiac life support (ACLS), pediatric advanced life support (PALS), and in 2014 issued the first guidelines for preventing strokes in women. The American Heart Association is also known for operating a number of highly visible public service campaigns starting in the 1970s, and also operates several fundraising events.
Women's health differs from that of men's health in many unique ways. Women's health is an example of population health, where health is defined by the World Health Organisation as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Often treated as simply women's reproductive health, many groups argue for a broader definition pertaining to the overall health of women, better expressed as "The health of women". These differences are further exacerbated in developing countries where women, whose health includes both their risks and experiences, are further disadvantaged.
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.
The Nuclear Threat Initiative, generally referred to as NTI, is a non-profit organization located in Washington, D.C. The American foreign policy think tank was founded in 2001 by former U.S. Senator Sam Nunn and philanthropist Ted Turner and describes itself as a "nonprofit, nonpartisan global security organization focused on reducing nuclear and biological threats imperiling humanity."
Global health is the health of the populations in the 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.
Health education is a profession of educating people about health. Areas within this profession encompass environmental health, physical health, social health, emotional health, intellectual health, and spiritual health, as well as sexual and reproductive health education.
Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age. It is a primary manifestation of malnutrition and recurrent infections, such as diarrhea and helminthiasis, in early childhood and even before birth, due to malnutrition during fetal development brought on by a malnourished mother. The definition of stunting according to the World Health Organization (WHO) is for the "height-for-age" value to be less than two standard deviations of the median of WHO Child Growth Standards. Stunted growth is usually associated with poverty, unsanitary environmental conditions, maternal undernutrition, frequent illness, and/or inappropriate feeding practice and care during early years of life.
The Partnership for Child Development (PCD) is a research and technical assistance group based at Imperial College London that seeks to improve health and nutrition in school-age children and youth in low-income countries, thereby improving their education outcomes. PCD was formed in 1992 at the University of Oxford to bridge gaps between academia, funding bodies and the education and health sectors in low-income countries.
The Grand Challenges in Global Health (GCGH) is a research initiative launched by the Bill & Melinda Gates Foundation in search of solutions to health problems in the developing world.

The disciplines involved include immunology, microbiology, genetics, molecular biology and cellular biology, entomology, agricultural sciences, clinical sciences, epidemiology, population and behavioral sciences, ecology, and evolutionary biology.
Breastfeeding promotion refers to coordinated activities and policies to promote health among women, newborns and infants through breastfeeding.
Global Health Initiatives (GHIs) are humanitarian initiatives that raise and disburse additional funds for infectious diseases – such as AIDS, tuberculosis, and malaria – for immunizations and for strengthening health systems in developing countries. GHIs classify a type of global initiative, which is defined as an organized effort integrating the involvement of organizations, individuals, and stakeholders around the world to address a global issue.
