A complete nutritional assessment integrates a combination of subjective medical evaluations and objective evaluation of the medical and nutritional history, including past and present dietary intake; physical examination, including anthropometric measurements and growth assessment; biochemical and metabolic parameters; and anticipation of the future medical course (including likely complications) and effects of therapy.

Nutritional assessment of an otherwise well child at a health maintenance examination differs from that of an infant or child with a chronic illness (see Chapter 10). A routine history should include a nutritional history with questions regarding family attitudes toward health foods, junk foods, dieting, fad diets, nutritional supplements, herbal remedies, and general nutrition. A healthy child on a routine visit to the doctor requires only a measurement of height, weight, and, for infants, head circumference (plotted on either the Centers for Disease Control [CDC] or World Health Organization [WHO] growth charts), along with a routine history and physical examination. If growth is normal and there are no unusual dietary habits, further assessment is not required.

Both the CDC and WHO growth charts provide meaningful data, especially when tracked over time. However, assessment of normal height and weight percentiles vary slightly when applying the 5th to 95th percentile ranges to the same children. The WHO charts are more likely to suggest shortness and overweight and are less likely to suggest underweight when compared to the CDC charts when 5th and 95th percentile cutoffs for normalcy are utilized. However, when the WHO-recommended cutoff values of z scores of –2 and +2 are applied to the WHO charts, these differences are lessened for shortness and overweight.1 The WHO charts consistently classify fewer children as underweight in early childhood years than do the CDC charts. The CDC growth charts are available at, and the WHO growth charts are available at Computer software to facilitate calculations of anthropomorphic data using the WHO charts is available at

The patient with poor growth or weight gain requires a more careful nutritional assessment. Any child with a history of poor growth or a chronic disorder placing him or her at risk for malnutrition should have periodic nutritional assessment.

It is challenging to obtain an accurate nutritional history. A 24-hour recall is the most commonly used method to obtain information about a child’s intake and is useful as a screening tool. Parents and other caregivers are asked to describe the types and amounts of food eaten by the child in the previous 24-hour period. This may not represent a typical day’s intake, so the recall may not accurately describe a child’s nutrient intake, and foods consumed between meals often are not recorded. Accuracy is improved by the use of food models for estimating portion sizes, but errors are common. The 24-hour recall is helpful during clinic follow-up to measure adherence to dietary recommendations. A 3-day or 7-day food record provides a more ...
