Maternal and neonatal clinical characteristics
Maternal and neonatal clinical data were retrieved from SJD Barcelona
Children’s Hospital and their Health Reference Center. In the event of
being unable to find particular data in the mother-child clinical
record, information was obtained from the sociodemographic questionnaire
filled by the parents (Table 1). From the initial 27 LGA recorded, 25
LGA were compared with 25 AGA paired by sex and GA at birth. Two LGA
with unreliable FFR (their SNR was <0) were excluded from the
analyses. Significantly higher pre-pregnancy weight (P = .03) and
pre-pregnancy body mass index (BMI) (P = .04), but not height
(P = .47), were found in LGA mothers compared to AGA mothers, as
well as higher incidence of maternal obesity (pre-pregnancy BMI ≥30
kg/m2) amongst LGA mothers than in AGA mothers
(P = .04). No group differences were found in any other of the
maternal characteristics assessed.
Regarding the neonatal clinical characteristics (Table 2), LGA neonates
presented, as expected, a significantly higher birth weight and centile
(P = <.001), length (P = .001), BMI and head
circumference (P = <.001) compared to AGA neonates. No
differences were observed in GA at birth, Time from birth to EEG
recording, GA at EEG recording, gender, labor induction, emergency
cesarean section, neonatal acidosis, and Apgar score lower than 7
assessed at 5 minutes of life.
