Recent studies have indicated that birth weight to placental weight (BW/PW) ratio is related to perinatal outcomes, but the effect of congenital abnormalities on BW/PW ratio remains unclear. We performed this study to elucidate correlations between BW/PW ratio and congenital abnormalities. Subjects were 735 singleton infants born at 34–41 weeks of gestation admitted to our center between 2010 and 2016. Of these, 109 infants (15%) showed major congenital anomalies. Major congenital anomalies and subgroups were diagnosed according to European Surveillance of Congenital Anomalies criteria. The primary outcome was the association between BW/PW ratio and major congenital anomaly, and secondary outcomes were the distribution pattern of BW/PW ratio with major anomalies and by major anomaly subgroups in each categorization (<10th percentile, 10–90th percentile, or >90th percentile) of BW/PW ratio. BW/PW ratio was not associated (P = 0.20) with presence (adjusted mean BWPW ratio = 5.02, 95% confidence interval [CI] 4.87–5.18) or absence (adjusted mean BW/PW ratio = 4.91, 95%CI 4.85–4.97) of major anomalies, after adjusting for gestational age and sex. Proportions of infants with major anomalies according to BW/PW ratio categories were as follows: 12% in <10th percentile, 15% in 10–90th percentile, and 25% in >90th percentile of BW/PW ratio. Among major anomalies of the nervous system, congenital heart defects, and orofacial clefts, BW/PW ratio showed equally distributed trend across the three BW/PW ratio categories, but showed unequally distributed trend for anomalies of the digestive system, other anomalies/syndromes, or chromosomal abnormalities. BW/PW ratio was not associated with major congenital anomaly, and was distributed diffusely according to major anomaly subgroups. Major anomalies may tend to aggregate in the 90th percentile of the BW/PW ratio.

Given that 1990s, scientists was basically wanting placental pounds (PW), and just have said connections anywhere between PW and you will perinatal consequences [1,2] therefore the growth of ailment inside adult lifestyle . Eutherian (placental) mammals show a near matchmaking anywhere between PW and you will fetal growth, and complete-identity birth weight (BW) regarding humans, pigs and you may goats is approximately five times the newest PW [4–6]. Individual PWs and you will complete-name BWs vary by more than 15% anywhere between various other events or places [4,7,8]. However, an entire-name BW-to-PW (BW/PW) proportion has been proven to simply disagree of the less than 5% anywhere between ethnicities otherwise nation regarding delivery [cuatro,seven,9]. This suggests your BW/PW ratio can offer a valuable around the globe perinatal index. A relatively large BW/PW ratio ways lack of placental outdoors also have into fetus. On datingranking.net/nl/amor-en-linea-overzicht/ the other hand, the lowest BW/PW ratio means a good suboptimal fetal reputation. Early in the day studies have shown connections off BW/PW ratio having perinatal consequences , likelihood of mind palsy and you may condition effects in the next adulthood . Whether or not congenital defects can impact fetal gains , this new relationship ranging from congenital defects and PW provides yet is elucidated [14,15]. We hypothesized you to definitely fetal congenital anomaly may lead to a decreased BW/PW ratio due to fetal gains maximum, or to a leading BW/PW proportion because of inappropriate fetal overgrowth. We examined whether relationships lived ranging from BW/PW proportion and you may biggest congenital defects as well as the significant anomaly subgroups.
