Facts On Childhood Obesity

  • Childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years.

  • The percentage of children aged 6–11 years in the United States who were obese increased from 7% in 1980 to nearly 18% in 2010. Similarly, the percentage of adolescents aged 12–19 years who were obese increased from 5% to 18% over the same period.

  • In 2010, more than one third of children and adolescents were overweight or obese.

  • Overweight is defined as having excess body weight for a particular height from fat, muscle, bone, water, or a combination of these factors. 

  • Obesity is defined as having excess body fat.

  • Overweight and obesity are the result of “caloric imbalance”—too few calories expended for the amount of calories consumed—and are affected by various genetic, behavioral, and environmental factors.

 

 

 

 

 

 

 

 

 

Immediate health effects:

  • Obese youth are more likely to have risk factors for cardiovascular disease, such as high cholesterol or high blood pressure. In a population-based sample of 5- to 17-year-olds, 70% of obese youth had at least one risk factor for cardiovascular disease.

  • Obese adolescents are more likely to have prediabetes, a condition in which blood glucose levels indicate a high risk for development of diabetes.

  • Children and adolescents who are obese are at greater risk for bone and joint problems, sleep apnea, and social and psychological problems such as stigmatization and poor self-esteem.

Childhood obesity has both immediate and long-term effects on health and well-being.

Health Effects of Childhood Obesity

Long-term health effects:

  • Children and adolescents who are obese are likely to be obese as adults and are therefore more at risk for adult health problems such as heart disease, type 2 diabetes, stroke, several types of cancer, and osteoarthritis. 

  • One study showed that children who became obese as early as age 2 were more likely to be obese as adults.

  • Overweight and obesity are associated with increased risk for many types of cancer, including cancer of the breast, colon, endometrium, esophagus, kidney, pancreas, gall bladder, thyroid, ovary, cervix, and prostate, as well as multiple myeloma and Hodgkin’s lymphoma.

What Is BMI

Body Mass Index (BMI) is a number calculated from a child's weight and height. BMI is a reliable indicator of body fatness for most children and teens. BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat, such as underwater weighing and dual energy x-ray absorptiometry (DXA).1 BMI can be considered an alternative for direct measures of body fat. Additionally, BMI is an inexpensive and easy-to-perform method of screening for weight categories that may lead to health problems.

For children and teens, BMI is age- and sex-specific and is often referred to as BMI-for-age.

.

What is a BMI percentile?

 

After BMI is calculated for children and teens, the BMI number is plotted on the CDC BMI-for-age growth charts (for either girls or boys) to obtain a percentile ranking. Percentiles are the most commonly used indicator to assess the size and growth patterns of individual children in the United States. The percentile indicates the relative position of the child's BMI number among children of the same sex and age. The growth charts show the weight status categories used with children and teens (underweight, healthy weight, overweight, and obese).

How is BMI used with children and teens?

 

BMI is used as a screening tool to identify possible weight problems for children. CDC and the American Academy of Pediatrics (AAP) recommend the use of BMI to screen for overweight and obesity in children beginning at 2 years old.

For children, BMI is used to screen for obesity, overweight, healthy weight, or underweight. However, BMI is not a diagnostic tool. For example, a child may have a high BMI for age and sex, but to determine if excess fat is a problem, a health care provider would need to perform further assessments. These assessments might include skinfold thickness measurements, evaluations of diet, physical activity, family history, and other appropriate health screenings.

How can I tell if my child is overweight or obese?

 

CDC and the American Academy of Pediatrics (AAP) recommend the use of Body Mass Index (BMI) to screen for overweight and obesity in children and teens aged 2 through 19 years. Although BMI is used to screen for overweight and obesity in children and teens, BMI is not a diagnostic tool.

For example, a child who is relatively heavy may have a high BMI for his or her age. To determine whether the child has excess fat, further assessment would be needed. Further assessment might include skinfold thickness measurements. To determine a counseling strategy, assessments of diet, health, and physical activity are needed.

 

 

 

Can I determine if my child or teen is obese by using an adult BMI calculator?

 

No. The adult calculator provides only the BMI number and not the BMI age- and sex-specific percentile that is used to interpret BMI and determine the weight category for children and teens. It is not appropriate to use the BMI categories for adults to interpret BMI numbers for children and teens.

What causes childhood obesity?

 

Childhood obesity is the result of eating too many calories and not getting enough physical activity.

 

 

Why focus on food and physical activity environments?

 

There are a variety of environmental factors that determine whether or not the healthy choice is the easy choice for children and their parents. American society has become characterized by environments that promote increased consumption of less healthy food and physical inactivity. It can be difficult for children to make healthy food choices and get enough physical activity when they are exposed to environments in their home, child care center, school, or community that are influenced by–

 

Sugary drinks and less healthy foods on school campuses. About 55 million school-aged children are enrolled in schools across the United States, and many eat and drink meals and snacks there. Yet, more than half of U.S. middle and high schools still offer sugary drinks and less healthy foods for purchase.2 Students have access to sugary drinks and less healthy foods at school throughout the day from vending machines and school canteens and at fundraising events, school parties, and sporting events.

  • Advertising of less healthy foods. Nearly half of U.S. middle and high schools allow advertising of less healthy foods, which impacts students' ability to make healthy food choices. In addition, foods high in total calories, sugars, salt, and fat, and low in nutrients are highly advertised and marketed through media targeted to children and adolescents, while advertising for healthier foods is almost nonexistent in comparison.

  • Variation in licensure regulations among child care centers. More than 12 million children regularly spend time in child care arrangements outside the home. However, not all states use licensing regulations to ensure that child care facilities encourage more healthful eating and physical activity.

Lack of daily, quality physical activity in all schools. Most adolescents fall short of the 2008 Physical Activity Guidelines for Americans recommendation of at least 60 minutes of aerobic physical activity each day, as only 18% of students in grades 9—12 met this recommendation in 2007. Daily, quality physical education in school can help students meet the Guidelines. However, in 2009 only 33% attended daily physical education classes.

  • No safe and appealing place, in many communities, to play or be active. Many communities are built in ways that make it difficult or unsafe to be physically active. For some families, getting to parks and recreation centers may be difficult, and public transportation may not be available. For many children, safe routes for walking or biking to school or play may not exist. Half of the children in the United States do not have a park, community center, and sidewalk in their neighborhood. Only 27 states have policies directing community-scale design.

Limited access to healthy affordable foods. Some people have less access to stores and supermarkets that sell healthy, affordable food such as fruits and vegetables, especially in rural, minority, and lower-income neighborhoods.9 Supermarket access is associated with a reduced risk for obesity. Choosing healthy foods is difficult for parents who live in areas with an overabundance of food retailers that tend to sell less healthy food, such as convenience stores and fast food restaurants.

  • Greater availability of high-energy-dense foods and sugary drinks. High-energy-dense foods are ones that have a lot of calories in each bite. A recent study among children showed that a high-energy-dense diet is associated with a higher risk for excess body fat during childhood. Sugary drinks are the largest source of added sugar and an important contributor of calories in the diets of children in the United States. High consumption of sugary drinks, which have few, if any, nutrients, has been associated with obesity. On a typical day, 80% of youth drink sugary drinks.

  • Increasing portion sizes. Portion sizes of less healthy foods and beverages have increased over time in restaurants, grocery stores, and vending machines. Research shows that children eat more without realizing it if they are served larger portions. This can mean they are consuming a lot of extra calories, especially when eating high-calorie foods.

Television and media. Children 8—18 years of age spend an average of 7.5 hours a day using entertainment media, including TV, computers, video games, cell phones, and movies. Of those 7.5 hours, about 4.5 hours is dedicated to viewing TV. Eighty-three percent of children from 6 months to less than 6 years of age view TV or videos about 1 hour and 57 minutes a day. TV viewing is a contributing factor to childhood obesity because it may take away from the time children spend in physical activities; lead to increased energy intake through snacking and eating meals in front of the TV; and, influence children to make unhealthy food choices through exposure to food advertisements.
