Obesity has been rated as the No.1 health problem for American children, according to a 2009 poll conducted by C.S. Mott Children’s Hospital. Up to one out of every five children in the U.S. is overweight or obese, and this number is continuing to grow. Obesity places children at risk of developing chronic diseases such as heart disease and diabetes later in life. The overweight children are also more prone to be depressed, anxious, and withdrawn, and report low self-esteem.
Children become overweight and obese for a variety of reasons. The most common causes are genetic factors, lack of physical activity, unhealthy eating patterns, or a combination of these factors. For example, psychologists explain that a combination of environmental pressures (e.g., parental concerns about children’s safety), technological factors (e.g., labor-saving devices such as cars), and societal transitions from childhood to adulthood are likely to increase sedentary behaviors, which usually coexist with eating, resulting in weight gain in children (Hills et al., 2007).
Although factors associated with and possible causes of obesity are complex, a child’s total diet and activity level play an important role in determining a child’s weight. Today, many children spend a lot time being inactive. For example, the average child spends approximately 4 hours each day watching television. As computers and video games become increasingly popular, the number of hours of inactivity may increase. Reducing the prevalence of childhood obesity is a public health challenge, and schools and parents have the potential to play a powerful role in diminishing this serious health crisis.
