As per BMI classification for overweight, pre-obese falls in :

Appeared in: IGNOU PB Bsc Nsg.Entrance-2026

Explanation

The World Health Organization (WHO) defines the 'pre-obese' category, also known as 'overweight', as having a Body Mass Index (BMI) between 25.00 and 29.99 kg/m².
This classification is standard for adults and is used globally to assess weight status and associated health risks.
BMI is calculated as weight in kilograms divided by the square of height in meters.
Individuals in the pre-obese range have an increased risk of developing comorbidities compared to those in the normal weight range.

Option A: A BMI of 40.00 or greater is classified as Obese Class III, which represents the most severe level of obesity (morbid obesity).
Option B: A BMI in the range of 35.00–39.99 is classified as Obese Class II.
Option C: A BMI in the range of 30.00–34.99 is classified as Obese Class I, which is the first stage of clinical obesity.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain WHO BMI classification for pre-obesity as background academic context rather than a clinical decision trigger.
Nurses use BMI as a quick screening tool to identify patients at risk for weight-related health problems like type 2 diabetes, hypertension, and cardiovascular disease.
Identifying a patient in the pre-obese category is a critical opportunity for preventative care. Nurses can provide education on lifestyle modifications (diet, exercise) to prevent progression to obesity.
What if? If the patient was of South Asian descent, the nurse should be aware that the risk for comorbidities like diabetes starts at a lower BMI. For Asian populations, a BMI greater than 23.0 is often considered overweight, and greater than 25.0 is considered obese, requiring earlier intervention.

How to Approach the Question

First, identify the key terms in the question: 'BMI classification' and 'pre-obese'.
Recognize that 'pre-obese' is another term for 'overweight'.
Recall the standard WHO BMI categories and their numerical ranges.
Compare the given options with the recalled ranges. The range for overweight/pre-obese is 25.00 to 29.99.
Select the option that matches this range.
