Small for gestational age (SGA) newborns are those who are smaller in size than normal for the gestational age. SGA is most commonly defined as a weight below the 10th percentile for the gestational age. [1] SGA predicts susceptibility to hypoglycemia, hypothermia, and polycythemia. [2] By definition, at least 10% of all newborns will be ...
Intrauterine growth restriction can result in a baby being small for gestational age (SGA), which is most commonly defined as a weight below the 10th percentile for the gestational age. [8] At the end of pregnancy, it can result in a low birth weight.
Small for gestational age is defined as below the 10th percentile for gestational age and sex. [11] Low birth weight can also be caused by health issues in the person giving birth, genetic factors, or problems in the placenta. [12] A very large birth weight is usually caused by the infant having been large for gestational age. Large birth ...
LBW is either caused by preterm birth (that is, a low gestational age at birth, commonly defined as younger than 37 weeks of gestation) or the infant being small for gestational age (that is, a slow prenatal growth rate), or a combination of both.
Small for gestational age infants Lula Olga Lubchenco (1915–2001) was an American pediatrician. Her family moved from Russian Turkestan to South Carolina when she was a small child, and Lubchenco's higher education and career were spent almost entirely in Colorado .
A baby born within the normal range of weight for that gestational age is known as appropriate for gestational age (AGA). An abnormally slow growth rate results in the infant being small for gestational age, while an abnormally large growth rate results in the infant being large for gestational age.
Fundal height, when expressed in centimeters, roughly corresponds to gestational age in weeks between 16 and 36 weeks for a vertex fetus. When a tape measure is unavailable, finger widths are used to estimate centimeter (week) distances from a corresponding anatomical landmark.
Fetal growth is often classified as follows: small for gestational age (SGA), appropriate for gestational age (AGA), and large for gestational age (LGA). [19] SGA can result in low birth weight, although premature birth can also result in low birth weight.
