The problem of childhood obesity in the United States has grown considerably in recent years. Between 16 and 33 percent of children and adolescents are obese. Obesity is among the easiest medical conditions to recognize but most difficult to treat. Unhealthy weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year. The annual cost to society for obesity is estimated at nearly $100 billion. Overweight children are much more likely to become overweight adults unless they adopt and maintain healthier patterns of eating and exercise.
What is obesity?
A few extra pounds does not suggest obesity. However they may indicate a tendency to gain weight easily and a need for changes in diet and/or exercise. Generally, a child is not considered obese until the weight is at least 10 percent higher than what is recommended for their height and body type. Obesity most commonly begins between the ages of 5 and 6, or during adolescence. Studies have shown that a child who is obese between the ages of 10 and 13 has an 80 percent chance of becoming an obese adult.
What causes obesity?
The causes of obesity are complex and include genetic, biological, behavioral and cultural factors. Obesity occurs when a person eats more calories than the body burns up. If one parent is obese, there is a 50 percent chance that their children will also be obese. However, when both parents are obese, their children have an 80 percent chance of being obese. Although certain medical disorders can cause obesity, less than 1 percent of all obesity is caused by physical problems. Obesity in childhood and adolescence can be related to:
- poor eating habits
- overeating or binging
- lack of exercise (i.e., couch potato kids)
- family history of obesity
- medical illnesses (endocrine, neurological problems)
- medications (steroids, some psychiatric medications)
- stressful life events or changes (separations, divorce, moves, deaths, abuse)
- family and peer problems
- low self-esteem
- depression or other emotional problems
What are risks and complications of obesity?
There are many risks and complications with obesity. Physical consequences include:
- increased risk of heart disease
- high blood pressure
- breathing problems
- trouble sleeping
Child and adolescent obesity is also associated with increased risk of emotional problems. Teens with weight problems tend to have much lower self-esteem and be less popular with their peers. Depression, anxiety, and obsessive compulsive disorder can also occur.
How can obesity be managed and treated?
Obese children need a thorough medical evaluation by a pediatrician or family physician to consider the possibility of a physical cause. In the absence of a physical disorder, the only way to lose weight is to reduce the number of calories being eaten and to increase the level of physical activity. Lasting weight loss can only occur when there is self-motivation. Since obesity often affects more than one family member, making healthy eating and regular exercise a family activity can improve the chances of successful weight control for the child or adolescent.
Ways to manage obesity in children and adolescents include:
- start a weight-management program
- change eating habits (eat slowly, develop a routine)
- plan meals and make better food selections (eat less fatty foods, avoid junk and fast foods)
- control portions and consume less calories
- increase physical activity (especially walking) and have a more active lifestyle
- know what your child eats at school
- eat meals as a family instead of while watching television or at the computer
- do not use food as a reward
- limit snacking
- attend a support group (e.g., Over-eaters Anonymous)
Obesity frequently becomes a lifelong issue. The reason most obese adolescents gain back their lost pounds is that they tend to go back to their old habits of eating and exercising. An obese adolescent must therefore learn to eat and enjoy healthy foods in moderate amounts and to exercise regularly to maintain a desired weight. Parents of an obese child can improve their child’s self esteem by emphasizing their strengths and positive qualities rather than just focusing on their weight problem.
