BMI (Body Mass Index) is also known as?

Appeared in: HPSSC Staff Nurse - 2021

Explanation

Body Mass Index (BMI) is also referred to as the Quetelet Index.
It is named after the Belgian astronomer, mathematician, and statistician Adolphe Quetelet, who developed the formula in the 19th century.
The index is a measure of relative body fatness calculated from a person's weight and height (Weight/Height²).
It is a standard tool used to classify individuals into weight categories such as underweight, normal weight, overweight, and obese.

Option B: The Broca Index is a formula used to estimate a person's ideal body weight, not a measure of body fatness like BMI.
Option C: The Corpulence Index, or Rohrer's Index, uses a different formula (weight/height³) and is not a synonym for BMI.
Option D: The Lorentz Index is another specific formula used to calculate ideal body weight, differing from the BMI which assesses body fatness relative to height.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Alternative name for Body Mass Index (BMI) as background academic context rather than a clinical decision trigger.
Nurses frequently calculate and document BMI during patient assessments as a quick screening tool for nutritional status and risk of chronic diseases like hypertension, diabetes, and cardiovascular disease.
A high BMI can prompt the nurse to provide patient education on healthy diet, exercise, and lifestyle changes, and to monitor for related health complications.
It's important for nurses to remember that BMI does not differentiate between fat and muscle mass. A muscular athlete may have a high BMI without having excess body fat.

How to Approach the Question

First, identify the core of the question, which is asking for a synonym or alternative name for 'Body Mass Index (BMI)'.
This is a factual recall question. Access your knowledge about anthropometric measurements and their history.
Recall that BMI was developed by Adolphe Quetelet in the 1800s.
Connect the creator's name, Quetelet, to the 'Quetelet Index' option in the list.
Briefly consider the other options (Broca, Corpulence, Lorentz) and recognize them as different indices for assessing weight or body composition, thus confirming they are incorrect distractors.
