Final answer:
Abdominal obesity is characterized by a waist circumference exceeding 35 inches in women and 40 inches in men, and is associated with significant health risks, not being the e. healthiest form of obesity.
Step-by-step explanation:
All of the following describe abdominal obesity EXCEPT that it is measured at the top of the rib cage.
Abdominal obesity is defined by a particular fat distribution pattern, where excess fat is stored in the abdomen, also described as an apple-shaped body.
It is not the e. healthiest type of obesity; in fact, abdominal obesity is associated with a higher risk of a number of health issues compared to fat distribution in other areas like the hips (pear-shaped body).
For women, abdominal obesity is present when the waist circumference exceeds 35 inches, and for men when it exceeds 40 inches.
However, the waist-to-hip ratio is often a better measurement for predicting disease risk than waist circumference alone. In men, a waist-to-hip ratio greater than 0.95 indicates excessive abdominal fat, and in women, a ratio greater than 0.86 does.
Central obesity, another term for abdominal obesity, poses greater risks including type 2 diabetes and cardiovascular disease.
Therefore, the statement that abdominal obesity is 'measured at the top of the rib cage' is incorrect. The measurement for assessing abdominal or central obesity is typically taken just above the belly button.
