Understanding Childhood Obesity (page 5)
What is Childhood Obesity?
Childhood obesity affects more than 30 percent of children, making it the most common chronic disease of childhood. Childhood obesity is not just a cosmetic problem. Today, more and more children are being diagnosed with diabetes, hypertension and other co-morbid conditions associated with obesity and morbid obesity. A child is defined as “overweight” if their weight-to-age percentile is greater than 95 percent. A child is defined as “at risk for overweight” if their weight-to-age percentile is greater than 85 percent and less than 95 percent.
Overweight or Obese?
Throughout the “Understanding Childhood Obesity” brochure, “overweight” and “obese” are used interchangeably. The Centers for Disease Control prefers the term “overweight,” while mass media often utilizes the term “obese” when referring to children.
Causes of Childhood Obesity
Although the causes of childhood obesity are widespread, certain factors are targeted as major contributors to this epidemic. Causes associated with childhood obesity include:
- Lack of physical activity
- Heredity and family
- Dietary patterns
- Socioeconomic status
Today’s environment plays a major role in shaping the habits and perceptions of children and adolescents. The prevalence of television commercials promoting unhealthy foods and eating habits is a large contributor. In addition, children are surrounded by environmental influences that demote the importance of physical activity.
Today, it is estimated that approximately 40 to 50 percent of every dollar that is spent on food is spent on food outside the home in restaurants, cafeterias, sporting events, etc. In addition, as portion sizes have increased, when people eat out they tend to eat a larger quantity of food (calories) than when they eat at home.
Beverages such as soda and juice boxes also greatly contribute to the childhood obesity epidemic. It is not uncommon for a 32 ounce soda to be marketed toward children, which contains approximately 400 calories. The consumption of soda by children has increased throughout the last 20 years by 300 percent. Scientific studies have documented a 60 percent increase risk of obesity for every regular soda consumed per day. Box drinks, juice, fruit drinks and sports drinks present another significant problem. These beverages contain a significant amount of calories and it is estimated that 20 percent of children who are currently overweight are overweight due to excessive caloric intake from beverages.
Lack of Physical Activity
Children in today’s society show a decrease in overall physical activity. The growing use of computers, increased time watching television and decreased physical education in schools, all contribute to children and adolescents living a more sedentary lifestyle.
Another major factor contributing to the childhood obesity epidemic is the increased sedentary lifestyle of children. School-aged children spend most of their day in school where their only activity comes during recess or physical education classes. In the past, physical education was required on a daily basis. Currently, only 8 percent of elementary schools and less than 7 percent of middle schools and high schools have daily physical education requirements in the U.S.
Only 50 percent of children, 12 to 21 years of age, regularly participate in rigorous physical activity, while 25 percent of children report no physical activity. The average child spends two hours a day watching television, but 26 percent of children watch at least four hours of television per day.
Heredity and Family
Science shows that genetics play a role in obesity. It has been proven that children with obese parents are more likely to be obese. Estimates say that heredity contributes between 5 to 25 percent of the risk for obesity. However, genes alone do not always dictate whether a child is overweight or obese. Learned behaviors from parents are a major contributor. Parents, especially of those whose children are at risk for obesity at a young age, should promote healthy food and lifestyle choices early in their development.
Over the past few decades, dietary patterns have changed significantly. The average amount of calories consumed per day has dramatically increased. Furthermore, the increase in caloric intake has also decreased the nutrients needed for a healthy diet. Food portions also play an important role in the unhealthy diet patterns that have evolved. The prevalence of “super size” options and “all you can eat” buffets create a trend in overeating. Combined with a lack of physical activity, children are consuming more and expending less.
Children and adolescents that come from lower-income homes are at greater risk of being obese. This is a result of several factors that influence behaviors and activities. Lower-income children cannot always afford to partake in extracurricular activities, resulting in a decrease in physical activity. In addition, families who struggle to pay bills and make a living often opt for convenience foods, which are higher in calories, fat and sugar.
Educational levels also contribute to the socioeconomic issue associated with obesity. Parents with little to no education have not been exposed to information about proper nutrition and healthy food choices. This makes it difficult to instill those important values in their children.
Measuring Obesity in Children
Weight categories for children and teens are defined so that they take into account normal differences in body fat between boys and girls and differences in body fat at various ages. Children’s weight categories are determined by measuring a child’s weight and then plotting them on a weight-to-age chart. There are separate weight-to-age curves for males and females, ages two to 20 years.
Treating Childhood Obesity
Treating obesity in children and adolescents differs from treatment in adults. Involving the family in a child’s weight management program is a key element to treatment. Treatment of pediatric obesity is not accomplished by just dieting. You need to address multiple aspects of the child and the family’s lifestyle, nutrition and physical activity patterns. Prior to discussing any treatment plans, you first must determine the desired goals. If your child is overweight, or at risk for becoming overweight, it is important to work with your healthcare provider to develop an individualized plan of care that includes realistic goals and action steps.
As a support system, family is integral in ensuring weight management goals are met. You must first assess the readiness of the child and the family to make changes. If the child is very depressed, this needs to be addressed prior to working on the child’s weight problem. If a depressed child attempts weight-loss and is unsuccessful, this may worsen their depression or lower their self-esteem.
Similarly, if there is a lot of stress in the family at that time it is not ideal to try and tackle yet another major issue. In some situations where there is significant depression or stress, it may be most appropriate for the child and the family to seek counseling to address these issues. In addition, if parents express little concern regarding their child being overweight, they are not ready to make the necessary changes.
It is important to talk with your physician about options for treating childhood obesity. The various treatments of obesity in children and adolescents include:
- Dietary therapy
- Physical activity
- Behavior modification
When treating an obese child or adolescent, it is often recommended that they have a consultation with a dietitian that specializes in children’s needs. Dietitians can best help children understand healthy eating habits and how to implement them in their long-term diet.
Dietitians do not always recommend restricting caloric intake for children. Education on how to read food labels, cut back on portions, understand the food pyramid and eat smaller bites at a smaller pace is generally the information given to change a child’s eating habits.
Another form of obesity treatment in children is increasing physical activity. Physical activity is an important long-term ingredient for children, as studies indicate that inactivity in childhood has been linked to a sedentary adult lifestyle.
Increasing physical activity can decrease, or at least slow the increase, in fatty tissues in obese children. The U.S. Surgeon General recommends that children get at least 60 minutes of physical activity each day. Individualized programs are available and possible for those children or adolescents that are not able to meet minimum expectations.
Lifestyles and behaviors are established at a young age. It is important for parents and children to remain educated and focused on making long-term healthy lifestyle choices. There are several ways that children and adolescents can modify their behavior for healthier outcomes, such as:
- Changing eating habits
- Increasing physical activity
- Becoming educated about the body and how to nourish it appropriately
- Engaging in a support group or extracurricular activity and setting realistic weight management goals
