*** WHAT'S COVERED ***
1. Definition and role of risk factors in increasing the chance of developing diseases.
* Focus on non-communicable diseases (e.g., coronary heart disease, diabetes, cancer).
2. Categorisation of risk factors.
* Lifestyle factors (e.g., diet, obesity, smoking, alcohol consumption, lack of exercise).
* Substances in the body or environment (e.g., air pollution, asbestos, radiation).
3. Interaction and direct causation involving risk factors.
* How multiple factors can contribute to conditions like cardiovascular disease.
* Examples where a risk factor directly causes a disease (e.g., smoking and lung cancer, alcohol and liver disease, obesity and type 2 diabetes).
4. Impact of diseases beyond the individual level.
* Effects on family and friends (e.g., need for support).
* National impact (e.g., workforce productivity, healthcare spending).
5. Correlation between population groups and disease incidence.
* Differences in risk factors and disease rates in developed countries.
* Increased risk factors (smoking, poor diet, lack of exercise) and related diseases (cardiovascular disease, obesity) in more deprived areas.
