Background: Obesity predominantly affects populations in high-income countries and those countries facing epidemiological transition. The risk of childhood obesity is increased among infants who had overweight or obesity at birth, but in low-resource settings one in five infants are born small for gestational age. We aimed to study the relationships between: (1) maternal metabolite signatures; (2) fetal abdominal growth; and (3) postnatal growth, adiposity, and neurodevelopment.

Background: Deleterious long-term effects in the offspring from women with pregravid obesity have been described; however, the evidence supporting early metabolic and inflammatory markers in the offspring at birth and gender differences are conflicting.

Objective: The present study aimed to compare cord blood adipokines and cytokines concentrations and anthropometric characteristics of the offspring of women with maternal obesity (MO) and normal-weight mothers (NWM). Also, maternal and neonatal variables on the association of maternal body mass index (BMI) with cord blood adipokines were evaluated.

Many observational studies and some randomized trials demonstrate how fetal growth can be influenced by environmental insults (for example, maternal infections) and preventive interventions (for example, multiple-micronutrient supplementation) that can have a long-lasting effect on health, growth, neurodevelopment and even educational attainment and income in adulthood. In a cohort of pregnant women (n = 3,598), followed-up between 2012 and 2019 at six sites worldwide, we studied the associations between ultrasound-derived fetal cranial growth trajectories, measured longitudinally from <14 weeks' gestation, against international standards, and growth and neurodevelopment up to 2 years of age. We identified five trajectories associated with specific neurodevelopmental, behavioral, visual and growth outcomes, independent of fetal abdominal growth, postnatal morbidity and anthropometric measures at birth and age 2.

To determine changes in global DNA methylation in monocytes from neonates of women with obesity, as markers of an immune programming resulting from maternal obesity. Cord blood monocytes were obtained from neonates born to women with obesity and normal weight, genome-wide differentially methylated CpGs were determined using an Infinium MethylationEPIC-BeadChip (850K). No clustering of samples according to maternal BMI was observed, but sex-specific analysis revealed 71,728 differentially methylated CpGs in female neonates from women with obesity (p < 0.

Article Synopsis
  • The study explored whether omega-3 fatty acid (docosahexaenoic acid) supplementation, combined with dietary counseling, could help prevent gestational diabetes in obese and overweight pregnant women.
  • 1002 participants were randomly assigned to one of four groups differing in the type of dietary counseling and the amount of omega-3 (800 mg or 200 mg per day).
  • Results showed a gestational diabetes incidence of 20.2% across groups, with average birthweight of 3403 g, indicating no significant impact from the interventions on these outcomes.

Background: A central aim for pediatric nutrition is to develop infant formula compositionally closer to human milk. Milk fat globule membranes (MFGM) have shown to have functional components that are found in human milk, suggesting that addition of bovine sources of MFGM (bMFGM) to infant formula may promote beneficial outcomes potentially helping to narrow the gap between infants who receive human breast milk or infant formula. The objective of the current study is to determine how the addition of bMFGM in infant formula and consumption in early infancy affects physical growth and brain development when compared to infants fed with a standard formula and a reference group of infants fed with mother's own milk.

Background: Growing evidence shows that atopic dermatitis (AD), food allergy (FA), allergic rhinitis, and asthma are largely determined during the first 1000 days (time elapsed from conception to the 2nd birthday). The ARIES birth cohort aims to determine prenatal and perinatal conditions, as well as genetic and epigenetic factors, that participate in the early setting of immune responses, and the role of these in the later determination of the risk of allergic diseases and asthma in the offspring.

Methods: We have designed a birth cohort of 250 families with prenatal recruitment (~ 14 weeks).

Background: Intimate partner violence (IPV) against women is a major global health issue, particularly in low- and middle-income countries (LMICs), that is associated with poor physical and mental health, but its association with breastfeeding practices is understudied. Both the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) recommend that children initiate breastfeeding within the first hour of birth and be exclusively breastfed for the first 6 months of life. Breastfeeding within the first hour of birth is critical to newborn survival, and exclusive breastfeeding for 6 months is recognised to offer significant health benefits to mothers and their infants.
