2.2 Factors relating to physical environment
Main inclusion criteria
Environmental or external factors associated with the cause, risk or development of disease, conditions or ill health including:
- physical agents, occupational hazards, environmental surroundings, radiation and pollution
- chemicals and nutrients
- infection by pathogens and studies of infectious agents
Advice on research activities
Involves characterising or identifying environmental or external factors that are determinants in the cause of conditions or disease e.g. studies of infectious agents.
Many studies will involve investigating the impact of environmental factors on biological systems. It may be appropriate to code to both 2.1 Endogenous risks as well as 2.2 Physical risks if the study involves investigating both the external agent and the biological response to that agent.
Excludes studies of infection with prion protein which should be coded as 2.1 Endogenous risks.
Excludes characterisation of antibiotic resistance genes and mechanisms in bacteria which should be coded as 5.1 Pharmaceuticals.

Common Scientific Outline (CSO) – 2.1 Exogenous Factors in the origin and cause of cancer
Common Scientific Outline (CSO) – 2.3 Interactions of Genes and/or Genetic Polymorphisms with Exogenous and/or Endogenous Factors
Main inclusion criteria
Identification and characterisation of endogenous factors known or suspected to be involved in the cause, risk or development of disease, conditions or ill health including
- genes and gene products, molecular, cellular and physiological structures and functions
- biological factors linked to ethnicity, age, gender, pregnancy and body weight
- endogenous biological factors or pathways involved in responses to infection or damage by external factors

Advice on research activities
To be used to code all biological causes of disease including the following

- ischemic preconditioning
Characterisation of pathways to identify candidates that may potentially be used as diagnostic markers should be coded as 2.1 Endogenous risks and not 4.1 Marker discovery.
Characterisation of the biological cause of psychological conditions should be coded as 2.1. However 2.3 Psychological risks can also be used if the study includes investigation of symptoms and characteristics of the psychological condition.
Awards that are focused on therapeutic development or diagnostics will often yield information about the mechanism of a disease. However, this is generally a secondary outcome and shouldn’t be coded 2.1 unless this is clearly stated as one of the primary objective of the research.
Excludes basic immune and pain responses and wound healing studies that are not linked to a specific disease/condition stimulus and normal ageing or pregnancy not linked to a condition which should be coded as 1.1 Biological normal function.
Excludes normal cell cycle and normal DNA repair and replication which should be coded as 1.1 Biological.
