SGA, AGA, and LGA infants were defined as lower than the 10th percentile, between the 10th and 90th percentile, and more than the 90th percentile for BW, respectively, based on GA and sex in accordance with Japanese neonatal anthropometric charts for gestational age at birth. 15 GA was determined in the following order: (1) early prenatal ultrasound, (2) the best estimation of the last menstrual period, and (3) physical examination at birth.
What is the difference between SGA and LGA?
Infants weighing less are considered small for gestational age (SGA) Infants weighing more are considered large for gestational age (LGA)
What does Aga stand for?
Appropriate for gestational age (AGA) Gestation is the period of time between conception and birth. During this time, the baby grows and develops inside the mother's womb.
What are the differences between Aga and LGA babies?

What does AGA mean in pregnancy?
During this time, the baby grows and develops inside the mother's womb. If the baby's gestational age findings after birth match the calendar age, the baby is said to be appropriate for gestational age (AGA).
What is considered LGA baby?
Large for gestational age (LGA) is used to describe newborn babies who weigh more than usual for the number of weeks of pregnancy. Babies may be called large for gestational age if they weigh more than 9 in 10 babies (90th percentile) of the same gestational age.
What causes a LGA baby?
What causes LGA? Some babies are large because their parents are large; genetics does play a part. Birthweight may also be related to the amount of weight a mother gains during pregnancy. Excessive weight gain can translate to increased fetal weight.
Do LGA babies gain weight slower?
In conclusion, our study showed that although LGA babies were larger and had greater adiposity at birth, a slowing in growth (length and weight) occurs in these infants in early infancy, leading to a similar anthropometry to AGA infants by 6 months of age.
Corrected gestational age
When a baby is born before their due date, they will have two ages: their corrected age and their chronological age. Your baby also had a gestational age, which was the age of your baby from conception to birth, calculated in weeks.
Small for gestational age
Small for gestational age also called low birth weight, is a term used to describe a baby or an infant who is smaller or less developed than normal for the baby’s gender and gestational age. Gestational age is the age of a fetus or baby that starts on the first day of the mother’s last menstrual period.
Large for gestational age
Large for gestational age is a term used to describe babies who are born weighing more than the usual amount for the number of weeks of pregnancy. Large for gestational age babies have birthweights greater than the 90th percentile for their gestational age, meaning that they weigh more than 90 percent of all babies of the same gestational age.
Gestational age vs Fetal age
Fetal age is the actual age of the growing baby. Gestational age is the age of the pregnancy from the last normal menstrual period (LMP). Most references to pregnancy are usually in gestational age rather than fetal age development.
How is physical maturity assessed?
The physical assessment part of the Dubowitz/Ballard Examination examines physical characteristics that look different at various stages of a baby’s gestational maturity. Babies who are physically mature usually have higher scores than premature babies.
How is neuromuscular maturity assessed?
Six evaluations of the baby’s neuromuscular system are performed. These include:
How to identify SGA?
SGA or Intrauterine Growth Restriction (IUGR) are usually identified by ultrasound before birth or an examination after birth. Birth weight below the 10th percentile of the population, corrected for gestational age, has been the most widely used definition of SGA and IUGR.
What is IUGR in pregnancy?
Intrauterine growth restriction ( IUGR) is a diagnosis made inside the uterus , prior to birth, when the fetus falls below a certain %tile (5th or 10th %tile) for the gestational age . Intrauterine growth restriction (IUGR) is usually diagnosed when the fetus falls below the 10th percentile curve for the gestational age.
What is a small for gestational age?
Small for gestational age (SGA) is defined when the newborn baby is below the 10th %tile for the gestational age. The definition depends on the exact week of the pregnancy, and sometimes can be adjusted for the ethnical group.
Abstract
Small for gestational age (SGA) infants have an increased risk for neonatal mortality and morbidities. However, few studies have examined the risk of large for gestational age (LGA) on these factors. We compared the risk of mortality and morbidities in LGA premature infants with those of appropriate for gestational age (AGA) infants.
Introduction
Infants who are born small for gestational age (SGA) are often associated with increased mortality. 1 SGA infants are also predisposed to hypoglycemia, 2 hypothermia, 3 polycythemia, 4 and thrombocytopenia 5 compared to infants born appropriate for gestational age (AGA) after birth.
Methods
This retrospective observational study cohort included all extremely premature infants born at <26 weeks of GA and admitted to a neonatal intensive care unit (NICU) registered in the NRNJ from January 01, 2003 to December 31, 2012. During the study period, about 60% of the participating NICUs were Level III and 40% were Level II units.
Results
In this study, a total of 7985 extremely premature infants who were born at less than 26 weeks of GA and who were admitted to a NICU participating in the NRNJ from January 01, 2003 to December 31, 2012 were enrolled in the study.
Discussion
In this comparative study of outcomes in LGA and AGA extremely premature infants in Japan, differences in mortality and morbidities were investigated between the two groups. The study highlighted that there were no statistical differences in mortality and morbidities between LGA and AGA extremely premature infants.
