An adult has their waist and hip circumferences measured at two health checks.
| Health check | Waist circumference in cm | Hip circumference in cm |
|---|---|---|
| 1 | 96 | 104 |
| 2 | 88 | 104 |
Calculate the decrease in the adult's waist-to-hip ratio between health check 1 and health check 2.
Give your answer to two decimal places.
Explain why this decrease alone cannot establish that the adult will remain free of cardiovascular disease and type 2 diabetes.
