Jones & Bartlett Learning (JBL) Module 3 Practice Exam

Which percent over ideal body weight defines obesity?

40% or more 10% or more 20% or more 30% or more

Correct Answer:

30% or more

Explanation:

Percent over ideal body weight is a way to gauge how much weight exceeds what’s expected for height. In this framework, obesity is defined as being at least 30% above ideal body weight. To see how it works, multiply the ideal weight by 1.30 to get the obesity threshold. For example, if ideal weight is 150 pounds, the obesity cutoff is 195 pounds; weights at or above 195 pounds are considered obese under this criterion. Values that are 10% or 20% over IBW don’t meet the obesity threshold, while 40% over IBW would also be obese, but 30% is the defined cutoff used here.
