Specific to public health policy, a determinant is a health risk that is general, abstract, related to inequalities, and difficult for an individual to control. [2] [3] [4] For example, poverty is known to be a determinant of an individual's standard of health. Risk factors may be used to identify high-risk people.
For example, various Global Burden of Disease Studies investigate such factors and quantify recent developments – one such systematic analysis analyzed the (non)progress on cancer and its causes during the 2010–19-decade, indicating that 2019, ~44% of all cancer deaths – or ~4.5 M deaths or ~105 million lost disability-adjusted life years ...
Attributable fraction for the population combines both the relative risk of an incident with respect to the factor, as well as the prevalence of the factor in the population. Values of AF p close to 1 indicate that both the relative risk is high, and that the risk factor is prevalent. In such case, removal of the risk factor will greatly reduce ...
The term arose in the context of infectious disease research, in contrast to "organism factors", such as the virulence and infectivity of a microbe. Host factors that may vary in a population and affect disease susceptibility can be innate or acquired. Some examples: [1] general health; psychological characteristics and attitude; nutritional state
Short term risks may include physical injury (e.g., eye, back, head, etc.), while long-term risks may be an increased risk of developing occupational disease, such as cancer or heart disease. In general, adverse health effects caused by short term risks are reversible while those caused by long term risks are irreversible.
A depiction of prevalence. In epidemiology, prevalence is the proportion of a particular population found to be affected by a medical condition (typically a disease or a risk factor such as smoking or seatbelt use) at a specific time. [1]
A limitation of many studies of health risk factors is confounding bias: many risk factors are interrelated and cluster together in high-risk populations. For example: Low physical activity and obesity go hand in hand. People who are physically inactive tend to gain weight, and people who are severely obese have difficulty exercising.
Conversely, a Risk factor will increase the chances of a negative health outcome occurring. Just as statistical correlations and regressions can examine how a range of independent variables impact a dependent variable, we can examine how many Protective and Risk factors contribute to the likelihood of an illness occurring.
