Causes of Childhood Obesity
There is no single cause of obesity in children. It’s often the result of a combination of multiple factors, including:

With the rise of screen time—TV, video games, smartphones, and computers—children are spending more time indoors and less time being physically active. This sedentary lifestyle leads to an imbalance between calories consumed and calories burned.

Children living in neighborhoods without access to parks, healthy food options, or safe places to exercise are at a greater risk. Financial constraints may also limit a family’s ability to buy nutritious foods.

Stress, depression, and low self-esteem can lead to emotional eating. Children may overeat to cope with their feelings, which contributes to weight gain.
