Similar to the concept of ecosystem health, the integrity of the ecosystem relies heavily on the processes that occur within it because those determine which organisms can inhabit an area and the complexities of their interactions. Deciding which of the many possible states or conditions of an ecosystem is appropriate or desirable is a ...
The presence or lack of macroinvertebrates such as insects, worms and snails in a river or stream can give a biological indicator on the health of that waterway. [2] The MCI assigns a number to each species of macroinvertebrate based on the sensitivity of that species to pollution. The index then calculates an average score. [1]
A biotic index is a scale for showing the quality of an environment by indicating the types and abundances of organisms present in a representative sample of the environment. It is often used to assess the quality of water in marine and freshwater ecosystems.
In genetics, a polygenic score (PGS) is a number that summarizes the estimated effect of many genetic variants on an individual's phenotype. The PGS is also called the polygenic index (PGI) or genome-wide score; in the context of disease risk, it is called a polygenic risk score (PRS or PR score [1]) or genetic risk score. The score reflects an ...
Frailty Index (FI) = (number of health deficits present) ÷ (number of health deficits measured) For example, a person with 20 of 40 deficits collected has an FI score of 20/40 = 0.5; whilst for someone with 10 deficits, the FI score is 10/40 = 0.25. The FI takes advantage of the high redundancy in the human organism.
[2] [3] For a physician, this score is helpful in deciding how aggressively to treat a condition. It is one of the most widely used scoring system for comorbidities. [4] The index was developed by Mary Charlson and colleagues in 1987, but the methodology has been adapted several times since then based on the findings of additional studies. [5]
Nutri-Score is a nutrition label guide recommended by the European Commission and World Health Organization. [3] It is a 5-color nutrition label selected by the French government in March 2017 for display on food products to facilitate consumer understanding of nutrient composition.
Health Score is a scoring system used by several mobile health companies in various ways to track an individual's health via Quantified Self and the help of mobile applications, social networking and elements of gamification. According to them when tracked over time, it offers a good directional indicator of how the users health and well-being ...
