IAL Edexcel Biology - Cardiovascular Disease (2): Risk Factors
Topic 1 Molecules Transport and Health
1.12 Know how factors such as genetics, diet, age, gender, high blood pressure, smoking and inactivity increase the risk of cardiovascular disease (CVD)
1.15 Be able to analyse and interpret quantitative data on illness and mortality rates to determine health risks, including distinguishing between correlation and causation and recognising conflicting evidence
1.16 Be able to evaluate the design of studies used to determine health risk factors, including sample selection and sample size used to collect data that is both valid and reliable
1.17 Understand why people’s perception of risks are often different from the actual risks, including underestimating and overestimating the risks due to diet and other lifestyle factors in the development of heart disease
Non-modifiable risk factors
Modifiable risk factors
👇 Understand the design of studies used to determine health risk factors for IAL Edexcel Biology 👇
When one variable changes with another variable, two variable are correlated. To prove causation, further experiment is required to prove the mechanism by which one factor causes another.
Actual risk vs perceived risk
