The table below is used to estimate a person's Metabolic Health Risk Index (MHRI). The higher a person's total point score, the greater their risk of developing metabolic complications.
| Risk factor | 1 point | 2 points | 3 points |
|---|---|---|---|
| Average daily sleep | More than 7 hours | 5–7 hours | Less than 5 hours |
| Daily refined sugar intake | Under 25 g | 25–50 g | Over 50 g |
| Cardio exercise (minutes/week) | More than 150 mins | 60–150 mins | Less than 60 mins |
| Waist-to-Height Ratio (WHtR) | Under 0.45 | 0.45–0.55 | Over 0.55 |
| Direct relatives with Type 2 Diabetes | 0 | 1 | 2 or more |
According to the table, how many points are scored by a person whose cardio exercise is 50 minutes per week?
What is the effect of a higher Waist-to-Height Ratio (WHtR) on the Metabolic Health Risk Index (MHRI)?
Here is some information about two patients:
Patient A:
Patient B:
Use the table to calculate whether Patient A or Patient B has a higher risk of developing metabolic complications. Show how you worked out your answer.
