In epidemiology, a risk factor or determinant is a variable associated with an increased risk of disease or infection. [ 1 ] : 38 Due to a lack of harmonization across disciplines, determinant , in its more widely accepted scientific meaning , is often used as a synonym.
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
Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population (e.g., increased stress or increase in the density of a vector species), a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a host population (by movement of pathogen or host).
The two investigations, one in the U.S. and one in Europe, showed that the niacin breakdown product, 4PY, predicted participants’ future risk of heart attack, stroke and death. The final part of ...
Typical risk factors for HCC need not be present with the acute hepatic porphyrias, specifically acute intermittent porphyria, variegate porphyria and hereditary coproporphyria. Porphyria cutanea tarda is also associated with HCC, but with typical risk factors including evidence of hepatotropic viruses, hemochromatosis and alcoholic cirrhosis ...
Among identical twins, if one is affected there is a 24% chance the other one will also develop the disease. [1] Female sex hormones, sunlight, smoking, vitamin D deficiency, and certain infections are also believed to increase a person's risk. [5] The mechanism involves an immune response by autoantibodies against a person's own tissues. [1]
They are the health promoting factors found in one's living and working conditions (such as the distribution of income, wealth, influence, and power), rather than individual risk factors (such as behavioral risk factors or genetics) that influence the risk or vulnerability for a disease or injury. The distribution of social determinants is ...
The factors are used to assist and promote colonization of the host. These factors include adhesins, invasins, and antiphagocytic factors. Bacterial flagella that give motility are included in these virulence factors. [5] The factors, including toxins, hemolysins and proteases, bring damage to the host.
