Last Update: November 14, 2022. Small for gestational age (SGA) is defined as a birth weight of less than 10th percentile for gestational age. The burden of fetal growth-restricted (FGR) SGA is higher in resource-poor countries, and children born FGR SGA have a higher risk of mortality and morbidity during the neonatal period and beyond.
Many SGA infants are healthy but just constitutionally small, and not all infants whose growth was restricted in utero are SGA (ie, weight is < the 10th percentile for gestational age).
The monthly SGA amount for statutorily blind individuals for 2024 is $2590. For non-blind individuals, the monthly SGA amount for 2024 is $1550 . SGA for the blind does not apply to Supplemental Security Income (SSI) benefits, while SGA for the non-blind disabled applies to Social Security and SSI benefits.
If intrauterine growth restriction is caused by chronic placental insufficiency, adequate nutrition may allow SGA infants to demonstrate remarkable “catch-up” growth after delivery. Infants who are SGA because of genetic factors, congenital infection, or maternal substance use often have a worse prognosis, depending on the specific diagnosis.
