These factors interact and these interactions may be health-promoting or deleterious. Thus, conceptually, the health of individuals and whole communities may be considered to be the result of many interactions.
- Biological
- Behavioural
- Environmental
- Socio-economic
- Health system
- Sociocultural
- Ageing of the population
- Science and technology
- Information and Communication
- Gender
- Equality and social justice
- Human rights
1. Biological Determinants- Genetic -Gene’s characteristics inherited from parents, make a person more likely or less likely to develop certain health problems, such as heart disease.
