[edit] 4000 or 4500?

"defined as a fetus that weighs above 4000 grams (8 lb 13 oz) or 4500 grams (9 lb 15 oz) regardless of gestational age". Don't these two figures contradict each other? Is it 4000 grams or 4500? Or am I misreading? Can someone fix or clarify? -anon 22:47, 1 August 2006 (UTC)

Sorry if it's not clear. It depends on who is defining it as some say it's over 4000 grams and some say over 4500. If I remember correctly it's partially down to the U.K./U.S./other divide. violet/riga (t) 23:06, 1 August 2006 (UTC)

[edit] sex of baby and weight

"The incidence of birth weight being outside of the AGA is influenced by the parents in numerous ways, including:

   * Genetics
   * The health of the mother, particularly during the pregnancy
   * Environmental factors"

Does the sex of the baby not play any part? What about when there are twins, don't they result in lower birth weights?

um, yes multiples do increase risk for SGA, as well as grand multipara, primapara, lack of prenatal care, low SES(socio economic status, third trimester malnutrition, heart/kidney disease, sub abuse, sickle cell anemia, PKU, comps of PIH, chronic hyperT, sm placenra, previa,


I cant figure out how to post a new thread so, on an unrelated topic, I have an issue with the comment under Asymmetric SGA that states thet the fetal head is disproportioned to the body measurements. I do not think this is an accurate defining charachteristic of ASGA. this may be the case hoeever, as a description I believe that most would agree that ONLY the weight falls below the 10th percentile. the baby is large in measurement but thin; lacking adipose tissue. any objections?
