(HealthDay News) -- Obesity is a major problem in the United States, and children are no exception. Today's kids are spending more hours watching TV, sitting at the computer or playing video games, and less time being active.

The Cleveland Clinic says the following factors make childhood obesity more likely:

• A genetic predisposition or family history of obesity.
• Not getting enough exercise.
• Eating unhealthy foods.
• Rarely, a health condition such as an endocrine disorder.
