Insights

Maternal obesity, small-for-gestational-age (SGA) birth, multiple births, and male sex are linked to developmental delays in moderately preterm children. Addressing these factors may improve developmental outcomes.

Area of Science:

  • Pediatric developmental neuroscience
  • Maternal-fetal medicine
  • Public health

Background:

  • Moderately preterm birth (32-35 weeks gestation) is associated with increased risks of developmental delay.
  • Identifying pre-existing maternal and pregnancy-related factors is crucial for early intervention.

Purpose of the Study:

  • To investigate the association between maternal and pregnancy-related factors and developmental delay in early childhood among moderately preterm-born children.

Main Methods:

  • Development was assessed using the Ages and Stages Questionnaire at 43-49 months in 834 moderately preterm children.
  • Data on maternal, fetal, and delivery factors were collected.
  • Adjusted odds ratios and attributable risks were calculated.

Main Results:

  • Small-for-gestational-age (SGA) was associated with a 14.2% attributable risk for developmental delay.
  • Maternal prepregnancy obesity showed a 10.5% attributable risk.
  • Multiple pregnancy and male sex were also significantly associated with increased risk.

Conclusions:

  • SGA, maternal obesity, multiple birth, and male sex are key risk factors for developmental delay in moderately preterm children.
  • Preventing intrauterine growth restriction, promoting preconception weight loss, and reducing multiple births may improve outcomes.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
