What is small gestational age?
Small for gestational age is a term used to describe a baby who is smaller than the usual amount for the number of weeks of pregnancy. SGA babies usually have birthweights below the 10th percentile for babies of the same gestational age.
What causes small for gestational age?
Some babies are small because their parents are small. But most babies who are small for gestational age have growth problems that happen during pregnancy. When the unborn baby does not get enough oxygen or nutrients during pregnancy, they don’t grow as much as normal. The condition is often suspected before birth.
What are the characteristics of small gestational age?
Small for gestational age (SGA) can be defined as neonates with a birthweight below the < 10th percentile customized for maternal factors such as parity, weight, height, and ethnicity [1–3]. SGA is associated with increased rates of stillbirth and neonatal death as well as metabolic disease in later life [1, 4–6].
What is the difference between SGA and FGR?
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.
What is SGA and LGA?
Infants weighing less are considered small for gestational age (SGA) Infants weighing more are considered large for gestational age (LGA)
What means SGA?
Small for gestational age
Small for gestational age (SGA) newborns are those who are smaller in size than normal for the gestational age, most commonly defined as a weight below the 10th percentile for the gestational age.
What are risk factors for SGA?
The confirmed maternal risk factors include short stature, low weight, Indian or Asian ethnicity, nulliparity, mother born SGA, cigarette smoking and cocaine use. Maternal medical history of: chronic hypertension, renal disease, anti-phospholipid syndrome and malaria are associated with increased SGA.
Can SGA babies be healthy?
Constitutionally normal babies with SGA usually have an excellent prognosis assuming there is no other health problem and the prognosis for babies with non–placenta mediated growth restriction will depend on the underlying condition.
When does SGA deliver?
The optimal gestation to deliver the SGA fetus Even when venous Doppler is normal, delivery is recommended by 32 weeks of gestation and should be considered between 30-32 weeks of gestation. If MCA Doppler is abnormal, delivery should be recommended no later than 37 weeks of gestation.
What is the difference between SGA and IUGR?
What are the differences between IUGR and being born SGA? IUGR describes a reduction of the fetal growth rate but is not defined by the subsequent birth weight, whereas birth weight is used to define SGA. It is therefore possible for a baby to be born SGA but with no prior IUGR.
What are the three categories of SGA?
There are 3 major categories for Gestational Age (GA): pre-term, post-term and term and within each category there are 3 size (birth weight) categories: small, acceptable (appropriate) and large.
What is SGA baby weight?
A baby is estimated to be due (the due date) at 40 weeks of gestation. At a gestational age of 40 weeks, boys who weigh less than about 6 pounds 9 ounces (3 kilograms) are small for gestational age. Girls who weigh less than about 6 pounds 3 ounces (2.8 kilograms) are small for gestational age.
Is SGA serious?
Babies whose growth at all gestational ages has been low. They are SGA but otherwise healthy. 50-70% of SGA fetuses are constitutionally small, with fetal growth appropriate for maternal size and ethnicity.
Can SGA babies catch up in the womb?
Premature IUGR/SGA babies may take longer to catch-up. However, research has found that about 10% of IUGR/SGA babies do not catch up in growth and remain small through adulthood, and these children can also face additional long-term health risks due to their intrauterine growth restriction.
Who is at risk for IUGR?
Pregnancies that have any of the following conditions may be at a greater risk at developing IUGR: Maternal weight less than 100 pounds. Poor nutrition during pregnancy. Birth defects or chromosomal abnormalities.
What is the leading cause of IUGR during pregnancy?
Placental insufficiency is the leading cause of IUGR: Placental Insufficiency: placental insufficiency (also called placental dysfunction) is a serious pregnancy complication where the placenta develops abnormally or becomes damaged.
