1. 25-29.9

2. 30-34.9

3. 35-39.9

4. ≥40

The correct answer is: 30-34.9

Class I obesity is categorized by a body mass index (BMI) range of 30 to 34.9. This classification is part of a broader system used to assess weight status based on height and weight, which helps identify areas of concern regarding health risks associated with obesity. BMI is calculated using the formula: weight in kilograms divided by the square of height in meters. Those within the Class I obesity range typically have a higher risk for developing various health issues, such as type 2 diabetes, hypertension, and cardiovascular diseases, compared to those in lower weight categories. Understanding these classifications can be crucial for identifying individuals who may benefit from lifestyle modifications or medical interventions to improve overall health. The other ranges correspond to different stages of weight status, with Class II obesity being 35 to 39.9 and Class III obesity being 40 and above. Knowing these distinctions is important for healthcare professionals when advising on health management and weight loss strategies.
