to investigate secular changes in mean birth weight and the prevalence of LBW and SGA in Surinamese South Asian babies, and 2. (biomedcentral.com)
In Surinamese South Asian babies from 1974 to 2009 no secular trend in mean birth weight and prevalence of LBW was found, whereas SGA prevalence decreased significantly. (biomedcentral.com)
It is unknown if this discrepancy is related to differences in birth weight or SGA prevalence. (biomedcentral.com)
While the mean birth weight of neonates born in the Netherlands increased from 3372 grams in 1989 to 3466 grams in the years 2008-2010 [ 13 ], it is unknown if the mean birth weight of South Asian babies born in the Netherlands has increased, or if the prevalence of LBW or SGA has decreased.

A 37-week-old baby has almost reached their birth weight. (conqueringmotherhood.com)
Furthermore, lithium use during pregnancy was associated with an average increase in birth weight of 142.43 grams (95% confidence interval: 58.01, 226.89), whereas it was associated with an average decrease of 1.41 weeks in gestational duration (95% confidence interval: −1.78, −1.05). (eur.nl)
The mean birth weight for macrosomic infants was 4.39 ± 0.43 (range 4-5.15) kg and males were more in number and weight. (bvsalud.org)

Background: Lithium is an effective treatment in pregnancy and postpartum for the prevention of relapse in bipolar disorder, but there is a lack of knowledge about the potential adverse impact on fetal development. (eur.nl)

The term "fetal macrosomia" is used to describe a newborn who's much larger than average. (sparrow.org)
Fetal macrosomia may complicate vaginal delivery and can put the baby at risk of injury during birth. (sparrow.org)
Fetal macrosomia also puts the baby at increased risk of health problems after birth. (sparrow.org)
Fetal macrosomia can be difficult to detect and diagnose during pregnancy. (sparrow.org)
A larger than expected fundal height could be a sign of fetal macrosomia. (sparrow.org)
Genetic factors and maternal conditions such as obesity or diabetes can cause fetal macrosomia. (sparrow.org)
Fetal macrosomia is more likely if you had diabetes before pregnancy (pre-gestational diabetes) or if you develop diabetes during pregnancy (gestational diabetes). (sparrow.org)
A history of fetal macrosomia. (sparrow.org)
Fetal macrosomia is more likely if you're obese. (sparrow.org)
Women older than 35 are more likely to have a baby diagnosed with fetal macrosomia. (sparrow.org)
Fetal macrosomia is more likely to be a result of maternal diabetes, obesity or weight gain during pregnancy than other causes. (sparrow.org)
Fetal macrosomia poses health risks for you and your baby - both during pregnancy and after childbirth. (sparrow.org)
Fetal macrosomia can cause a baby to become wedged in the birth canal (shoulder dystocia), sustain birth injuries, or require the use of forceps or a vacuum device during delivery (operative vaginal delivery). (sparrow.org)
During childbirth, fetal macrosomia can cause a baby to injure the birth canal - such as by tearing vaginal tissues and the muscles between the vagina and the anus (perineal muscles). (sparrow.org)
Fetal macrosomia increases the risk that your uterine muscles won't properly contract after you give birth (uterine atony). (sparrow.org)
If you've had a prior C-section or major uterine surgery, fetal macrosomia increases the risk of uterine rupture during labor - a rare but serious complication in which the uterus tears open along the scar line from the C-section or other uterine surgery. (sparrow.org)

The risk of inducing thermal effects is greater in the second and third trimesters, when fetal bone is intercepted by the ultrasound beam and significant temperature increase can occur in the fetal brain. (thehealthyskeptic.org)
The women were in their second and third trimesters, and fetal gender distribution was 55 males and 45 females. (bvsalud.org)
