Which of the following is a medical issue linked to obesity in children?

Obesity in children is associated with a number of serious health issues, one of the most significant being high blood pressure. When children are overweight or obese, they often face increased workload on their hearts and blood vessels, leading to elevated blood pressure levels. This condition can set the stage for various cardiovascular problems later in life, such as heart disease and stroke. The relationships between obesity and high blood pressure stem not just from excess body fat but also from associated factors like poor diet, lack of physical activity, and metabolic changes.

In contrast, the other options provided do not represent medical issues linked to obesity. Increased creativity, higher energy levels, and improved social skills are not direct consequences of obesity and do not reflect the associated medical risks that obesity presents in children.
