Y1 - 2011 N1 - T2 - Rudolph's Pediatrics, 22e AB - Failure to thrive describes the condition of infants and toddlers under age 3 years who have an abnormally low weight for their age and sex. With prolonged and/or severe malnutrition, stature and head circumference can be secondarily affected. The prevalence of failure to thrive is reported to be 10% to 20% of all children treated in ambulatory care centers and up to 5% of all referrals to pediatric hospitals.1 Regardless of specific etiology, failure to thrive may have profound effects on the growing child, including persistent short stature, decreased resistance to infection, and possible developmental impairment and/or disabilities.2,3 SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/28 UR - accesspediatrics.mhmedical.com/content.aspx?aid=6733255 ER -
