Physical Appearance, Performance, and Health
The most common of all measurements made on the human body are height and weight. From birth until maturity, these physical variables are frequently measured by family members and health personnel to evaluate a child's rate of growth and maturation. Height and weight are often plotted against chronological age to identify possible growth irregularities that may be symptomatic of a health problem or disorder. Even when there is no physical difficulty, children often worry about their height and weight and whether they are normal or abnormal. This concern, especially with regard
to weight, continues after maturity and may lead to obsessive dieting, exercising, and other procedures for overcoming any perceived irregularity.
