The first obstetric scan conducted by a sonographer at 19 weeks estimated gestational age
, indicated a single fetus with estimated weight of 302 g and adequate liquor (AFI=11.6 cm).
Participants were dyads (mother and child), including black and white women with at least 1 prenatal 25 (OH)D) level, had a non-low-birthweight child born at least 36 weeks estimated gestational age
, and had a 3-year study visit that included respiratory and atopic disease assessment.
Within this period, each participant's urine sample was measured for UIC, once in every trimester, at estimated gestational age
(EGA) of 11, 20, and 32 weeks.
Fetal measurements corresponded to an estimated gestational age
of 7 weeks 1 day.
Inclusion criteria were birth at less than 32 weeks' estimated gestational age
and the availability of data for 72 hours before and 72 hours after immunization.
The first day of her last menstrual period was 18th of October 2012 and the estimated gestational age
at presentation was 41 weeks and 2 days.
For instance, ACOG and SMFM suggest that clinicians "consider" antenatal corticosteriod administration when the estimated gestational age
is 23 weeks.
All infants with an estimated gestational age
of 34 weeks and less, with follow-up until the retina was completely vascularized or ROP was regressed were included in this study.
The stratum corneum is fully developed in utero by 32 to 34 weeks' estimated gestational age
based on 600,000 singleton live-born infants with ultrasound estimated gestational age
of 22 to 43 weeks .
The estimated gestational age
for each dam was established by sonography performed before gestation day (GD) 40.
Estimated gestational age
was approximately 38 weeks on the basis of prenatal ultrasound performed during the first trimester of pregnancy.
