Final answer:
Childhood obesity increases the risk for many health problems including high blood glucose levels, which can lead to conditions like type 2 diabetes and heart disease.
Step-by-step explanation:
Childhood obesity is a distressing trend that significantly increases the risk for many health problems in children. Of the options provided, childhood obesity most notably leads to high blood glucose levels (D). It does not lead to high HDL cholesterol, which is considered the "good" cholesterol, nor does it typically result in low blood pressure. In fact, obesity often causes high blood pressure due to the added strain on the heart and blood vessels. Obesity in children is defined by a body weight that is at least 20 percent higher than a healthy weight for a child of that height. This condition leads to an array of health issues, including type 2 diabetes, heart disease, high cholesterol, and increased blood pressure. The increase in childhood obesity has led to more children today weighing more than children in previous generations, which consequently increases their risk for these conditions.
