“…Overall, AF size was not correlated with GA or birth weight in this cohort study. This is in contrast to previous studies reporting a decrease of AF size with increasing GA [9,11] or increasing birth weight. [7][8][9]11] Because our study included only nursery babies, the impact of low GA or low birth weight was excluded.…”

“…When comparing the extremely large AF-sized group with other populations, SGA head circumference was also frequent. Some studies reported a negative correlation with small head circumference [8,9,11] or no significant correlation with small head circumference, [5] contrary to our study. In this study, SGA head circumference significantly correlated with SGA weight.…”

“…We assumed a large AF as an AF size > 3.6 cm in clinical practice. [10,11] Newborn infants with a large AF were examined for other bony abnormalities (by physical examinations), intracranial lesions (by brain ultrasonography), thyroid dysfunction (by blood tests), and abnormal calcium/vitamin D status (by blood tests) as routine medical practice. Blood tests were performed at 3 to 5 days after birth when the infant reached discharge status.…”

Anterior fontanel (AF) sizes in newborns are influenced by ethnicity, gender, genetics, nutrition, and other pathological conditions. However, AF sizes in recent Korean newborns have not been reported yet. Thus, this study aimed to understand variation in AF size and clinical implications of large AF sizes in newborns. This cohort study was conducted on nursery newborns born at a University Hospital between September 2019 and August 2020. AF size was measured at 24 to 48 hours after birth. Newborns with a large AF (> 3.6cm) were examined for other pathological reasons using radiological and laboratory tests. Demographic data were analyzed in relation to AF size. A total of 573 newborns were investigated. Their mean gestational age was 38.5 ± 1.2 weeks at birth and their mean birth weight was 3140 ± 450 g. Their mean AF size was 1.85 ± 0.83 cm (90 and 97-percentile of AF size were 2.96 and 3.65 cm, respectively). Among demographic factors, small for gestational age (SGA) weight, SGA head circumference, and multiple births were correlated with larger AF size. Among 18 infants with a large AF, 2 had intracranial abnormalities and 11 had vitamin D deficiency. This is the first recent study on AF sizes of Korean newborn infants. Their mean AF size was the smallest so far. For the largest AF size, a cutoff of 3.65 cm met the 97-percentile of the cohort. Both SGA weight and head circumference were risk factors for large AF size. For the largest AF size, intracranial lesions and vitamin D deficiency as well as SGA presented clinical implications.

“…Further investigation on the effects of gestational age on birth outcomes showed that the mean weight and length of infants born in less than 37 weeks of pregnancy (preterm birth) were noticeably lower than those of infants born between 37 and 42 weeks (term birth). Head circumference of preterm infants was about 2 cm smaller than that of term infants, which is an important factor influencing infants' health in the early and later stages of life and increasing the risk of having an abnormal fontanel diameter by 52% (Woldeyes et al 2020). Determination of international standards for newborn weight, length, and head circumference according to gestational age showed that the number of preterm birth in Asian pregnant women was higher than that in Europe.…”

In recent decades, emerging environmental pollutants such as endocrine-disrupting chemicals (EDCs) have become a particular concern. This study examined the association of maternal exposure to benzophenones as one of the EDCs with gestational age and evaluated their effects on birth outcomes including birth weight, birth length, head circumference, and Ponderal Index. We assessed 166 pregnant mothers of the PERSIAN cohort population of Isfahan, Iran, in the 1st and 3rd trimesters of pregnancy and their infants at birth. Four common benzophenones (BPs) including 2,4-dihydroxy benzophenone (BP-1), 2-hydroxy-4-methoxy benzophenone (BP-3), 4-hydroxy benzophenone (4-OH-BP), and 2,2′-dihydroxy-4-methoxy benzophenone (BP-8) were measured in maternal urine samples. The median urinary concentrations of 4-OH-BP, BP-3, BP-1, and BP-8 in the 1st trimester were 6.62, 7.5, 4.39, and 1.32 µg/g creatinine and those in the 3rd trimester were 3.15, 16.98, 9.95, and 1.04 µg/g creatinine, respectively. BP-3 was the predominant metabolite in both trimesters. There was a significant correlation between BP-3, BP-1, and 4-OH-BP levels (p < 0.05) but not BP-8. BP-1 showed a significant positive association with gestational age (GA) in all infants in the 1st trimester, but a negative association was observed between BP-3 and BP-1 levels and GA in girls. Classification of infants' birth weight for different GAs represented that the majority of them were appropriate for GA. However, boys' weights were heavier than girls. Also, birth outcomes of preterm (< 37 weeks) infants were noticeably lower than term infants (37-42 weeks). This study demonstrated that benzophenone derivatives especially BP-3 can affect the duration of pregnancy and consequently fetal growth in the early and late stages of pregnancy. This is more pronounced in girls; however, more investigations in a different population are needed to prove the results. Therefore, the application of these compounds as a UV protector requires precise regulation to reduce exposure, especially in pregnant women.
