What value defines class 1 obesity in terms of body mass index (BMI)?

Class 1 obesity is defined by a body mass index (BMI) range of 30 to 34.9. Thus, the value that specifically indicates the threshold for class 1 obesity is 30. This classification is important in understanding and diagnosing obesity because it helps healthcare professionals assess risk factors related to various health conditions, such as cardiovascular disease, diabetes, and hypertension that are associated with varying levels of obesity.

The threshold of 30 establishes this category, allowing for a clear distinction between different severity levels of obesity, which further guides treatment and intervention strategies. Therefore, identifying the starting point of class 1 obesity as 30 underscores its significance in managing health outcomes related to weight.
