Nutritional Issues: Toddler to Adolescent T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=6732956 RD 2024/04/24 AB The rate of physical growth during the toddler, preschool, and childhood years slows substantially when compared to the growth rate of an infant. A growth spurt that requires large increases in caloric intake occurs at puberty. Nutrient needs vary accordingly and substantially, as outlined in the dietary reference intakes (DRIs) for various age ranges (Chapter 23, eTable 23.1). Calorie needs have the greatest variability. The DRIs for energy for 1 to 2 years of age are based on age and weight, while those after 3 years include allowances for gender, height, and physical activity (Chapter 23, eTables 23.1 and 23.2). The general guidelines must be adjusted to account for individual variation in body size, stage of growth, physical activity, and state of health or illness.
