Risk factors

By Mayo Clinic staff

Many factors — usually working in combination — increase your child's risk of becoming overweight:

  • Diet. Regularly eating high-calorie foods, such as fast foods, baked goods and vending machine snacks, can easily cause your child to gain weight. Loading up on soft drinks, candy and desserts also can cause weight gain. Foods and beverages like these are high in sugar, fat and calories.
  • Lack of exercise. Children who don't exercise much are more likely to gain weight because they don't burn calories through physical activity. Inactive leisure activities, such as watching television or playing video games, contribute to the problem.
  • Family history. If your child comes from a family of overweight people, he or she may be more likely to put on excess weight, especially in an environment where high-calorie food is always available, and physical activity isn't encouraged.
  • Psychological factors. Some children overeat to cope with problems or to deal with emotions, such as stress, or to fight boredom. Their parents may have similar tendencies.
  • Family factors. If many of the groceries you buy are convenience foods, such as cookies, chips and other high-calorie items, this can contribute to your child's weight gain. If you can control your child's access to high-calorie foods, you may be able to help your child lose weight.
  • Socioeconomic factors. Children from low-income backgrounds are at greater risk of becoming obese. It takes both time and resources to make healthy eating and exercise a family priority.
