According to the data, how does a person's relative risk of premature death change in correlation to changes in physical activity?

A. The risk of dying prematurely increases as people become more physically active.
B. The risk of dying prematurely does not change in correlation to changes in physical activity.
C. The risk of dying prematurely declines as people become more physically active.
D. The risk of dying prematurely declines as people become less physically active.



Answer :

To understand how a person’s relative risk of premature death changes in correlation to changes in physical activity, we need to analyze the provided data.

Here is the data to consider:

| Minutes per Week of Moderate/Vigorous Physical Activity | Relative Risk of Premature Death |
|---------------------------------------------------------|----------------------------------|
| 30 minutes | 1 (reference risk) |
| 90 minutes | 0.8 |
| 180 minutes | 0.73 |
| 330 minutes | 0.64 |
| 420 minutes | 0.615 |

Let’s break down what this data implies:

1. 30 minutes per week of physical activity corresponds to a relative risk of 1. This is taken as the reference risk.
2. 90 minutes per week of physical activity corresponds to a relative risk of 0.8. Since 0.8 is less than 1, this indicates a reduction in risk.
3. 180 minutes per week of physical activity corresponds to a relative risk of 0.73. Again, 0.73 is less than 0.8, showing a further reduction in risk.
4. 330 minutes per week of physical activity corresponds to a relative risk of 0.64. This is a continued reduction in risk from previous values.
5. 420 minutes per week of physical activity corresponds to a relative risk of 0.615. This trend continues to show a decreased risk.

From this analysis, it is clear that as the amount of physical activity per week increases, the relative risk of premature death decreases.

Therefore, the correct interpretation of the data is:
- The risk of dying prematurely declines as people become more physically active.

So, the correct answer is:

The risk of dying prematurely declines as people become more physically active.
