Which of the following changes is a common indicator of insulin resistance in children?

High body mass index (BMI) is a common indicator of insulin resistance in children. Elevated BMI often correlates with increased body fat, particularly in the abdominal region, which is associated with metabolic disorders, including insulin resistance. In children, insulin resistance can manifest as difficulty in glucose metabolism, which is frequently linked to excess weight.

Research indicates that with the rising prevalence of obesity among children, the incidences of insulin resistance are concurrently increasing. A higher BMI serves as a straightforward and effective measure for assessing the risk of developing not only insulin resistance but also related complications such as type 2 diabetes.

On the other hand, while increased appetite can be a symptom related to various metabolic conditions, it is not a direct indicator of insulin resistance by itself. Normal blood pressure does not typically provide clear insight into insulin sensitivity and could be seen in both insulin-sensitive and insulin-resistant individuals. Delayed growth may occur in some metabolic syndromes, but it is less commonly recognized as a direct indicator of insulin resistance in the same way that high BMI is.
