What is delayed growth and development in children?

Growth and developmental delay in children refers to a condition in which a child's growth rate or developmental sequence significantly lags behind that of healthy peers of the same age. It is specifically manifested as physical development indicators—such as height, weight, and head circumference—falling below the average levels for children of the same age, or delays in motor skills, language, intelligence, and other developmental areas. Causes of growth and developmental delay are diverse, including genetic factors, malnutrition, chronic diseases, and endocrine abnormalities. The incidence rate ranges between 6% and 8%, and this condition may negatively affect a child's physical health, academic performance, and psychological well-being. Therefore, parents should closely monitor their child's growth and development, promptly identifying and intervening in cases of growth and developmental delay.
