Final answer:
To calculate Jonia's WHR, measure the waist and hip circumference and divide the waist by the hip measurement. Jonia's WHR would indicate her risk of abdominal obesity and associated chronic diseases.
Step-by-step explanation:
To calculate Jonia's waist-to-hip ratio (WHR), you need to take two measurements: the waist circumference and the hip circumference at the widest part. Once you have these two numbers, you divide the waist measurement by the hip measurement.
Here's the formula:
WHR = Waist Circumference / Hip Circumference
For instance, if Jonia's waist measures 28 inches and her hips are 36 inches, the calculation would be:
WHR = 28 inches / 36 inches = 0.777
According to the information provided, for females, a WHR above 0.85 indicates excessive abdominal fat and potential health risks. By comparing Jonia's result to this benchmark, we can assess her risk for chronic diseases associated with abdominal obesity.
