Anthropometry is the measurement of body size, weight and proportion. In infants and children growth data, regularly obtained by accurate measurements, can be an indicator of health status and/or an effective screening tool for referral to nutrition services provided by the registered dietitian (RD) experienced in pediatrics. Growth attainment is often the critical objective data on which clinical interventions are based; therefore, accuracy is essential. Weight for age, height or length for age, and weight/length or Body Mass Index (BMI – for those age 2 and older) should always be plotted. Head circumference should be measured and plotted during the first two years of life.
The best information about growth is shown through a series of plotted measurements forming a growth curve. Regular measurements recorded on growth charts may indicate trends of excessive or inadequate increases in weight or length or height. This is especially true for children with special health care needs (CSHCN). At times the growth of some CSHCN is less than typical for age. A series of measurements that follows a curve can reassure both the parents/caregivers and the health care professionals that growth is occurring or it can be an indication of the need for a referral to the RD due to concerns about growth. CSHCN may be at increased risk for inappropriate growth patterns due to their disability, repeated medical crisis situations, or inability to consume adequate amounts of food. However, individual interpretations of growth patterns for all children should be made using not only growth charts but other assessment tools including a food history and intake record, a review of medical issues, and laboratory data.
