RT Book, Section A1 Jeha, George S. A2 Kline, Mark W. SR Print(0) ID 1182918685 T1 Growth and Growth Impairment T2 Rudolph's Pediatrics, 23e YR 2018 FD 2018 PB McGraw-Hill Education PP New York, NY SN 9781259588594 LK accesspediatrics.mhmedical.com/content.aspx?aid=1182918685 RD 2024/04/24 AB Growth is an extraordinarily complex process governed by multiple factors: genetic, epigenetic, environmental, and psychosocial. As such, growth in children integrates the genetic and environmental influences at the level of individual cells, organs, and the organism as a whole, providing a window into the functioning of any organism, in particular children. Growth is the bellwether of health, and its evaluation is the cornerstone of pediatrics. Children who grow normally must have all the genetic and environmental requisites for growth in place. Those who do not should be looked at carefully to discover the cause, whether it is genetic, environmental, or a systemic disease, either endocrine or nonendocrine.
