Is This Information Right for Me?
This information is for you if:
- You care for a child between the ages of 5 and 18 years. If your child is younger than 5 years, you may still find this information helpful.
- You want to know things that can be done at home, in school, and in the community to help children maintain a healthy weight and keep them from becoming overweight or obese. If a child is already overweight or obese, steps can still be taken to keep the child from gaining any more weight.
What will this summary cover?
This summary will cover:
- How to know if your child is at a healthy weight
- What body mass index (BMI) is and what BMI percentiles are
- What health problems being overweight or obese could cause in a child
- What might lead to a child becoming overweight or obese
- What can be done at home, in school, and in the community to help keep children from becoming overweight or obese
- What researchers have found about things that can be done at home, at school, and in the community
This summary can help you talk with your child’s doctor*, school, and community leaders about keeping your child at a healthy weight.
* In this summary, the term “doctor” refers to your child’s health care professional, including your child’s pediatrician, family medicine physician, nurse practitioner, or physician assistant.
Where does the information come from?
Researchers reviewed 124 studies on ways to prevent children and adolescents from becoming obese. These studies were published between November 1985 and August 2012. The researchers were funded by the Agency for Healthcare Research and Quality (AHRQ), a Federal Government research agency.
The researchers wrote a report on what they found, and this summary is based on that report. The report was reviewed by doctors, researchers, other experts, and the public. You can read the report at www.effectivehealthcare.ahrq.gov/child-obesity-prevention.cfm.
Understanding Obesity in Children
How do I know if my child is at a healthy weight?
Your child’s doctor will track your child’s height and weight over time and can tell you if your child is at a healthy weight. During wellness checkups, be sure to talk with your child’s doctor about your child’s weight.
Your child’s doctor may ask you about:
- Your child’s eating habits
- Whether you have places to get healthy food for your child
- How much physical activity your child gets
- Whether there are safe places for your child to run around and play
- How much screen time your child has each day (time spent watching television, playing video games, or sitting in front of a computer, cell phone, or tablet such as an iPad)
- Any health problems your child has
- Your family’s medical history
What is BMI and what are BMI percentiles?
To find out if your child is in a healthy weight range, your child’s doctor may use something called BMI, or “body mass index.” BMI is a measurement based on your child’s height and weight. BMI helps the doctor estimate how much body fat your child has. The doctor can use BMI to see if your child is at a healthy weight for his or her height. A healthy BMI is different for girls and boys and changes by age.
Your doctor may compare your child’s BMI to the typical BMI range for children of the same sex and age. To do so, doctors may use what is called a “BMI percentile.” This can help the doctor figure out if a child is underweight, at a healthy weight, overweight, or obese.
According to the Centers for Disease Control and Prevention (CDC), children are considered:
- At a healthy weight if their BMI is between the 5th and 85th percentile
- Overweight if their BMI is between the 85th and 95th percentile
- Obese if their BMI is in the 95th percentile or above
To calculate your child's BMI and BMI percentile, go to http://apps.nccd.cdc.gov/dnpabmi/.
What health problems can being overweight or obese cause for a child?
Children who are overweight or obese are more likely to be overweight or obese as adults. They are also more likely to develop serious health problems such as:
- High blood sugar or diabetes
- High blood pressure
- High cholesterol (a type of fat in the blood)
- Sleep apnea (a condition in which you stop breathing for brief periods of time while you sleep)
- Heart problems (such as heart attack or heart failure) or a stroke as an adult
- Extra pressure on bones and joints, which could lead to bone and joint problems both as a child and as an adult
- Nonalcoholic fatty liver disease (a disease caused by too much fat in the liver)
- Low self-esteem or depression
- Eating disorders such as binge eating and purging
What might lead to a child becoming overweight or obese?
Many things can lead to a child becoming overweight or obese, including:
- Unhealthy eating habits. Children may eat too much, eat too many unhealthy foods, or drink too many sugary drinks.
- Not getting enough sleep. Children who do not get enough sleep each night are more likely to become overweight.
- Family history. Children from overweight families may be more likely to become overweight. This could be due to a child’s genes or learned family eating habits.
- Not enough physical activity. Children may not get enough physical activity. Children should be active for at least 1 hour each day.
- Too much screen time. Children may have too much screen time during the day. Some children may eat while watching television or playing on the computer.
- Environment. Children may spend time in an environment (such as with relatives, with friends, in childcare, or at school) where healthy eating choices or opportunities for physical activity are not available.
Keeping Your Child From Becoming Overweight or Obese
How can I keep my child from becoming overweight or obese?
To help keep your child from becoming overweight or obese, make sure your child eats healthy and is physically active. There are many things that can be done at home, in school, and in the community to help keep children at a healthy weight. Some examples of each are listed below.
There are many things you can do at home as a family. Some examples include:
- Cook healthy meals at home with foods from each food group.
- The food groups include fruits, vegetables, grains, protein foods (such as meats, eggs, fish, tofu, and beans), and low-fat or nonfat dairy.
- Be sure to eat a healthy breakfast every day.
- Eat at the table as a family instead of in front of a screen (television, computer, cell phone, or tablet).
- Limit or do not keep unhealthy foods and drinks at home.
- Replace unhealthy snacks such as cookies, candy, or chips with healthy snacks such as fruits and vegetables.
- Replace unhealthy sugary drinks such as sodas, sports drinks, or juices with healthy drinks such as water and low-fat or nonfat milk.
- Eat most meals at home instead of at restaurants. At home, you are better able to limit the amount of fat, sugar, and salt in your meals.
- Be sure to eat the right amount of food.
Be physically active
- Give your child a chance to run around and play – at least 1 hour a day.
- Plan fun activities like bicycling, walking to the park, playing ball, or swimming.
- Encourage everyone in the family to be active during the day.
- For example, take the stairs instead of the elevator and walk or bike places instead of driving or taking the bus.
- Limit the amount of screen time each day.
- In addition to being physically active, make sure your child gets enough sleep each night.
Let’s Go! is a program to keep children from becoming obese. The program focuses on healthy eating and physical activity.
Let’s Go! recommends the “5-2-1-0” healthy habits for each day:
- 5 fruits and vegetables
- 2 hours or less of screen time for recreation
- 1 hour or more of physical activity
- 0 sugary drinks
Let’s Go! also recommends keeping television and computers out of your child’s bedroom and not allowing screen time for children younger than 2 years.
In addition to eating healthy and being physically active at home, school programs can help keep children at a healthy weight. School programs could include things such as:
- Lessons about the importance of healthy eating and physical activity
- Information sessions for parents to learn ways to help keep their child at a healthy weight
- Healthy breakfast and lunch options in the cafeteria with the right portion sizes
- Healthy snacks and drinks in vending machines and at parties and events
- Filtered water coolers to encourage drinking water instead of soft drinks or sports drinks
- Adult-led walk-to-school or bike-to-school groups
- A longer physical education (PE) period in which children are physically active
- Gym equipment such as balls and jump ropes for use during recess
Let’s Go! also has resources for schools to help children eat healthy and be physically active. For more information and toolkits for your child’s school, go to www.letsgo.org/toolkits/.
In the Community
In addition to home and school, things can also be done in the community to help keep children at a healthy weight. Communities and community centers can:
- Improve community parks, sidewalks, and biking paths.
- Take steps to make parks, sidewalks, and biking paths safe.
- Advertise community events such as health fairs, 5K walks, sports events at local parks, community garden programs, and local farmers markets. This can be done on posters, in local newspapers, and on local television and radio stations.
- Offer programs in which families can get advice on healthy eating and being physically active.
For other resources to help keep your child at a healthy weight, go to:

What have researchers found about doing things at home, in school, and in the community to help keep children from becoming overweight or obese?
Healthy eating and physical activity are very important in keeping children from becoming overweight or obese.
Researchers found that:
- Programs at schools to help children eat healthy and be physically active can keep children from becoming overweight or obese.
- Along with school programs, additional steps at home and in the community can also help.
- More research is needed to know which particular programs or steps work the best.
