About 17 percent of children and adolescents in the United States are overweight. This serious health problem extends from preschoolers to teens; both groups in this country are increasingly overweight. Excess weight interferes with proper growth of leg and hip bones, creating both immediate and lifelong problems. Troubling problems associated with being overweight and obesity also include
diabetes, sleep apnea, social and psychological problems, high cholesterol, and elevated blood pressure. Children who continue to be overweight into adulthood are at greater risk for serious health problems, including
heart disease,
stroke, and some cancers.
At least once a year, a health care provider should assess the child’s weight. This is the recommendation of a federally convened “expert committee,” one that represents 15 national health care organizations. The child’s height, weight, age, and gender are considered in determining the child’s body mass index (BMI) percentile.
Overweight: An overweight child (one whose BMI is between the 85th percentile and the 94th percentile) faces additional health risks.
Obese: An obese child (at or above the 95th percentile) faces even more serious health risks.
Being overweight is one of the most common problems seen by pediatricians. At each well-child visit, the following should be discussed: the child’s dietary patterns, levels of physical activity, and sedentary behaviors. The family’s history of obesity, type 2 diabetes, and high blood pressure are important considerations as are a number of other physical measurements the health care provider can take. The goal is to prevent and address the problems of overweight and obesity through education and early interventions.
The health care provider will discuss the health threats and the changes the child and family can make to avoid them. Cholesterol testing, for example, is appropriate to begin when the child is overweight. Type 2 diabetes is also a threat for overweight children.
Children’s body mass calculations need to be accurate and related to their growth charts. A visit to a health care provider will provide you with the most reliable information, but the calculator at the following web site helps you see if your child is at risk of being overweight. This CDC website uses slightly different terminology than used above.
