Obesity is a major risk factor for several non-communicable lifestyle diseases, including Type 2 diabetes and cardiovascular disease. Clinicians often use the Waist-to-Height Ratio (WHtR) to assess abdominal adiposity and evaluate a patient's risk of developing these diseases.
The chart below is used to classify an adult's health risk category based on their height and waist circumference.
a.[2]
An adult is 1.75 m tall and has a waist circumference of 110 cm. What is this person's health risk category?
b.[3]
Another adult is 1.80 m tall. Using the grid, determine the range of waist circumferences that would place this person in the Increased Risk category.
