Final answer:
Childhood obesity is linked to negative outcomes such as depression, reduced exercise, and excess screen time, but not to improved executive functioning, which is not a consequence of obesity.
Step-by-step explanation:
Childhood obesity has been linked to several negative health outcomes, but not to improved executive functioning. This condition is characterized by excess body fat that negatively affects a child's health or well-being. Factors that contribute to obesity in children include a sedentary lifestyle, depression, reduced exercise, and excess screen time.
In contrast, improved executive functioning is associated with better cognitive processes such as problem-solving, memory, and impulse control, and is not a consequence of obesity. Obesity has often been connected to poorer executive functioning due to health-related complications. Therefore, improved executive functioning is not linked to childhood obesity and is the correct answer to the question.
