At present, the literature reports on the incidence of small for gestational age (SGA) infants in the world are not uniform, ranging from 6.61% to 12.28%. Compared with appropriate for gestational age (AGA) infants, SGA infants have higher mortality, and higher perinatal complications and long-term complications. Early identification of SGA infants related risk factors and complications, and timely intervention are the key to improve their long-term prognosis. The author intends to review the latest research progress in three aspects about epidemiological research status of SGA infants, high risk factors and prevention of SGA infants, perinatal complications and prognosis of SGA infants, and intervention measures for SGA infants after birth and related measures to improve prognosis, in order to provide reference for further clinical research on the diagnosis and treatment of SGA infants.
