Research findings on effects of prenatal phthalate exposure on fetal growth were inconsistent. Increasing evidence from animal studies has indicated a potential sex-specific effect of phthalates on fetal growth, but the current human data was limited. In this study, we aimed to estimate the relationships between maternal phthalate exposure and infant birth size. Six major phthalate metabolite levels of urine samples were measured among pregnant women (n=1002) from the Healthy Baby Cohort (HBC), China. The associations between urinary phthalate metabolites levels and birth size (birth weight, birth length, birth weight z-scores and ponderal index) were estimated using linear regression models. In boys, the ln-transformed di-2-ethylhexyl phthalate (DEHP) metabolite levels were significantly associated with increased birth weight and birth weight z-scores. Additionally, each ln-unit increase in mono-(2-ethyl-5-carbox-ypentyl) phthalate (MECPP) was associated with a 0.25kg/m [95% confidence interval (CI): 0.03, 0.47] increase in ponderal index in boys. However, we did not observe any significant association of maternal phthalate metabolite levels with any of the outcomes in girls. Our data suggested potential sex-specific associations of maternal phthalate exposure with increased birth weight and ponderal index, which were merely apparent in boys.

Gluten-free diet during pregnancy and pregnancy outcome: A retrospective cohort study.
Int J Gynaecol Obstet
January 2025
Faculty of Medicine and Health Technology, Center for Child, Adolescent, and Maternal Health Research, Tampere University, Tampere, Finland.
Objective: A gluten-free diet (GFD) is becoming increasingly popular, especially among young females, and including those without diagnosed celiac disease (CD). Whether a GFD is appropriate during pregnancy remains unclear. Our primary aim was to evaluate the association of a GFD and neonatal birthweight and incidence of large for gestational age (LGA) and small for gestational age (SGA).

Background: Early identification of developmental delay in children can help in making early intervention for its management. Routine developmental screening is not being practised in India due to lack of trained field workers, lack of awareness among parents and lack of feasible assessment screening tool. There is lack of studies that focuses on home environment provided to the children as it is associated with developmental delay.

Objective: The maternal metabolic environment in early pregnancy can influence fetal growth trajectories. Our objective was to identify interventions initiated in early pregnancy (<20 weeks gestation) in pregnant individuals with risk factors for hyperglycemia and report their impact on primary (neonatal adiposity, small for gestational age, large for gestational age, macrosomia) and secondary outcomes (gestational weight gain, maternal hypertensive disorder, birth injury, NICU admission, preterm delivery, emergency cesarean section).
Data Sources: We searched Cochrane Central database, Medline, Embase, CINAHL databases, and clinicaltrials.

Objective: To investigate the relationship between DNA methylation of cord blood apoptosis genes and low birth weight (LBW).
Methods: A case-control study was conducted on 50 pairs of LBW neonates and normal birth weight. Genome-wide methylation assay was performed using Illumina Human Methylation EPIC microarray to analyze the methylation sites of apoptosis-related genes BCL-2, CASP3, and CASP8.
Drivers of stunting and wasting across serial cross-sectional household surveys of children under 2 years of age in Pakistan: potential contribution of ecological factors.

Background: The impact of direct and indirect drivers on linear growth and wasting in young children is of public health interest. While the contributions of poverty, maternal education, empowerment and birth weight to early childhood growth are well recognized, the contribution of environmental factors like heat, precipitation, agriculture outputs and food security in comparable datasets is less well established.
Objectives: To investigate the association of length-for-age z-score (LAZ) and weight-for-length z-score (WLZ) with various indicators among children under 2 years of age in Pakistan using representative household level nutrition surveys and ecological datasets.
