Assessing Nutritional Risk Among Infants and Toddlers in Primary Care Practice.

Traditionally, nutritional risk has been defined by growth failure, with clinical intervention indicated when a child falls below the third to fifth percentile on growth charts. Although the velocity of linear growth and weight gain during the first years are unparalleled at any other time of life, this period is also unique for other reasons. Nutrition not only supports increased bone length, muscle mass, and tissue growth, but also continued development of several highly metabolic organs such as the gastrointestinal tract, the immune system, the cardiorespiratory system, the kidneys, and the central nervous system. Just as growth depends on consistent nutrients, so too does organ development, especially the brain. The undernourished child may exhibit compromised optimal development and future cognitive performance, irrespective of weight status. It is often challenging in early childhood to ensure that a child is receiving high-quality nutrition. Primary care clinicians are positioned to identify the child with potential nutritional risk and design an appropriate intervention that promotes optimal development.
