In the United States, at least one child in five is overweight, and the number of overweight children continues to grow. A doctor determines whether children are overweight by measuring their height and weight. Although children have fewer weight-related health problems than adults, overweight children are at high risk of becoming overweight adolescents and adults. Overweight adults are at risk for a number of health problems, including heart disease, diabetes, high blood pressure, stroke and some forms of cancer.
Children become overweight for a variety of reasons.
Your physician can perform a careful physical exam and some blood tests, if necessary, to rule out this type of problem. Genetic Factors Children whose parents or brothers or sisters are overweight may be at an increased risk of becoming overweight themselves. Although weight problems run in families, not all children with a family history of obesity will be overweight. Genetic factors play a role in increasing the likelihood that a child will be overweight, but shared family behaviors such as eating and activity habits also influence body weight. A child's total diet and his or her activity level both play important roles in determining a child's weight.
