An individual with a BMI value of 28 would be described as ______.

Appeared in: Raj. CHO - 2023

Explanation

Body Mass Index (BMI) is a standard measure used to assess a person's weight status relative to their height.
According to the World Health Organization (WHO) classification, a BMI between 25.0 and 29.9 kg/m² is categorized as overweight.
An individual with a BMI of 28 kg/m² falls directly within this range, making 'Overweight' the correct description.

Option A: This is incorrect. The 'Underweight' category is defined by a BMI of less than 18.5 kg/m².
Option C: This is incorrect. 'Obesity' is diagnosed when an individual has a BMI of 30.0 kg/m² or greater.
Option D: This is incorrect. The 'Normal' or healthy weight range corresponds to a BMI of 18.5 to 24.9 kg/m².

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Body Mass Index (BMI) Classification as background academic context rather than a clinical decision trigger.
BMI is a crucial initial screening tool for identifying weight-related health risks. Being overweight (BMI 25-29.9) significantly increases the risk of developing chronic conditions like type 2 diabetes, hypertension, and cardiovascular disease.
Nurses play a key role in calculating BMI during patient assessments and using this information to provide health education on nutrition, exercise, and lifestyle modifications to prevent obesity and its complications.
What if? If the individual was of South Asian descent, a BMI of 28 would often be classified as obese, not just overweight. For many Asian populations, the cut-off for obesity is a BMI of 25.0 or greater due to a higher risk of metabolic diseases at lower BMI values.

How to Approach the Question

First, identify the key piece of data in the question: the BMI value is 28.
Second, recall the standard WHO classification ranges for adult BMI.
Third, compare the given BMI value (28) to the established ranges: Underweight (<18.5), Normal (18.5-24.9), Overweight (25.0-29.9), and Obesity (≥30).
Finally, determine which category the value of 28 falls into. Since 28 is between 25.0 and 29.9, the correct classification is Overweight.
