The table below is used to estimate a person's Hypertension Risk Score (HRS). The higher a person's total point score, the greater their risk of developing hypertension.
| Risk factor | 1 point | 2 points | 3 points |
|---|---|---|---|
| Age (years) | Under 30 | 30–45 | Over 45 |
| Daily salt intake | Low | Medium | High |
| Physical activity (hours/week) | More than 5 hours | 2–5 hours | Less than 2 hours |
| Body Mass Index (BMI) | Under 25 | 25–30 | Over 30 |
| Family history (grandparents with hypertension) | 0 | 1–2 | 3–4 |
According to the table, how many points are scored by a person whose physical activity is 1.51.51.5 hours per week?
What is the effect of a higher Body Mass Index (BMI) on the Hypertension Risk Score?
Here is some information about two people:
Person X:
Person Y:
Use the table to calculate whether Person X or Person Y has a higher risk of developing hypertension. Show how you worked out your answer.
