Which characteristic is associated with children who are obese?

Obesity is typically associated with higher blood pressure rather than lower blood pressure. Children who are obese often experience increased strain on their cardiovascular system, leading to conditions such as hypertension. Therefore, low blood pressure is not a characteristic linked to childhood obesity.

Insulin resistance is commonly observed in children who are obese, resulting from excess body fat, particularly around the abdomen. This condition can lead to type 2 diabetes and other metabolic issues, making the statement that obese children have "no insulin resistance" incorrect.

While obesity can affect many life aspects, including social interactions and self-esteem, it does not correlate with higher academic achievement. In fact, children who are obese may face challenges that hinder their academic performance, such as absenteeism due to health issues or social difficulties, making this choice inaccurate.
