Background: Young maternal age is associated with poorer birth outcomes, but the mechanisms are incompletely understood. Using data from a prospective cohort of pregnant women living in Mumbai slums, India, we tested whether lower maternal age was associated with adverse fetal growth. Methods: Fetal crown-rump length (CRL) was recorded at a median (interquartile range, IQR) of 10 weeks’ gestation (9-10 weeks). Head circumference (HC), biparietal diameter (BPD), femur length (FL), and abdominal circumference (AC) were recorded at 19 (19-20) and 29 (28-30) weeks. Newborns were measured at a median (IQR) of 2 days (1-3 days) from delivery. Gestation was assessed using prospectively collected menstrual period dates. Results: The sample comprised 1653 singleton fetuses without major congenital abnormalities, of whom 1360 had newborn measurements. Fetuses of younger mothers had smaller CRL (0.01 standard deviation [SD] per year of maternal age; 95% confidence interval CI: 0.00-0.02 1 ; P = .04), and smaller HC, FL, and AC at subsequent visits. Fetal growth of HC (0.04 cm; 95% CI: 0.02-0.05; P < .001), BPD (0.01 cm; 95% CI: 0.00-0.01; P = .009), FL (0.04 cm; 95% CI: 0.02-0.06; P < .001), and AC (0.01 cm; 95% CI: 0.00-0.01; P = .003) up to the third trimester increased with maternal age. Skinfolds, head, and mid-upper arm circumferences were smaller in newborns of younger mothers. Adjusting for maternal prepregnancy socioeconomic status, body mass index, height, and parity attenuated the associations between maternal age and newborn size but did not change those with fetal biometry. Conclusion: Fetuses of younger mothers were smaller from the first trimester onward and grew slower, independently of known confounding factors.

Gestational age assessment is one of the most important tool used for estimation of perinatal morbidity and mortality. Age estimation of fetus can be recorded with the help of various parameters such as biparietal diameter, abdominal circumference, head circumference, length of the kidneys, crown rump length, length of the long bones and ossification centers.

Abstract Background According to the WHO Multicentre Growth Reference Study Group recommendations, boys and girls have different growth trajectories after birth. Our aim was to develop gender-specific fetal growth curves in a low-risk population and to compare immediate birth outcomes. Methods First, second, and third trimester fetal ultrasound examinations were conducted between 2002 and 2012. The data was selected using the following criteria: routine examinations in uncomplicated singleton pregnancies, Caucasian ethnicity, and confirmation of gestational age by a crown-rump length (CRL) measurement in the first trimester. Generalized Additive Model for Location, Scale and Shape (GAMLSS) was used to align the time frames of the longitudinal fetal measurements, corresponding with the methods of the postnatal growth curves of the WHO MGRS Group. Results A total of 27,680 complete scans were selected from the astraia© ultrasound database representing 12,368 pregnancies. Gender-specific fetal growth curves for biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) were derived. The HC and BPD were significantly larger in boys compared to girls from 20 weeks of gestation onwards (p < 0.001) equating to a 3-day difference at 20–24 weeks. Boys were significantly heavier, longer, and had greater head circumference than girls (p < 0.001) at birth. The Apgar score at 1 min (p = 0.01) and arterial cord pH (p < 0.001) were lower in boys. Conclusions These longitudinal fetal growth curves for the first time allow integration with neonatal and pediatric WHO gender-specific growth curves. Boys exceed head growth halfway of the pregnancy, and immediate birth outcomes are worse in boys than girls. Gender difference in intrauterine growth is sufficiently distinct to have a clinically important effect on fetal weight estimation but also on the second trimester dating. Therefore, these differences might already play a role in early fetal or immediate neonatal management.

Postdate pregnancy is a pregnancy that pasts more than forty weeks. This can be dangerous for the mother, fetus, and newborn. By knowing the most appropriate ultrasound criteria in predicting the probability of postdate pregnancy, its complications can be reduced by taking timely measures. Therefore, the present study was conducted with the aim of determining the relationship between ultrasound criteria in determining the age of postdate fetuses. This cross-sectional study (descriptive-analytical type) was done in Kermanshah Imam Reza Hospital on 33 pregnant women that, according to LMP and first-trimester ultrasound, pregnancy age was more than 40 weeks. Gestational age was calculated by various ultrasound criteria, including head circumference measurement (HC), Abdominal Circumference (AC), Biparietal Diameter (BPD), femur length (FL), and Transcerebellar Diameter (TCD). The findings were compared with calculated age by LMP. Data were analyzed by SPSS16 software. Correlation rate of pregnancy age based on LMP with FL (R=0.576, P<0.001), AC (R=0.208, P=0.245), BPD (R= -0.200, P=0.264), HC (R= -0.211, P=0.238) and TCD were (R=0.111, P=0.538). The pregnancy age correlation rate based on LMP with ultrasound criteria in general was (R=0.140, P=0.436). There was a direct relationship between gestational age based on LMP with FL, AC, TCD and inversely related to BPD and HC. Among the sonographic criteria, only the FL criterion was significantly correlated with LMP. In general, the correlation between gestational age based on LMP and ultrasound was not statistically significant.
