About Obesity in Children
Obesity means having too much body fat. It is different from being overweight, which means weighing too much. Both terms mean that a person's weight is greater than what's considered healthy for his or her height. Children grow at different rates, so it isn't always easy to know when a child has obesity or is overweight. Ask your health care provider to check whether your child's weight and height are in a healthy range.
If a weight-loss program is necessary, involve the whole family in healthy habits so your child doesn't feel singled out. Encourage healthy eating by:
- Serving more fruits and vegetables
- Buying fewer soft drinks and high-fat, high-calorie snack foods
- Making sure your child eats breakfast every day
- Eating fast food less often
- Not using food as a reward
Physical activity is also very important. Kids need about 60 minutes each day. It does not have to happen all at once. Several short periods of activity during the day are just as good.
It sits within Children and Teenagers, Food and Nutrition and Metabolic Problems.
The lead U.S. institute for this subject is the National Institute of Diabetes and Digestive and Kidney Diseases.
When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.
Research on Obesity in Children
1,658 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.
What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
