Tidsramme |
|---|---|---|
|
Maternal methyl-nutrient and other nutrition status
Tidsramme: From enrollment to delivery (approximately 9 months)
|
Maternal methyl-nutrient status will be assessed using the following measurements:
|
From enrollment to delivery (approximately 9 months)
|
|
Birth anthropometric measurements of the newborn
Tidsramme: At birth
|
This outcome will be assessed using medical records, including birth weight (grams), birth length (centimeters) , birth head circumference (centimeters), and gestational age at birth (weeks).
|
At birth
|
|
Infant neurodevelopmental outcomes
Tidsramme: At 6, 12, and 24 months of age
|
Infant neurodevelopment will be assessed using the Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-IV), including composite scores for cognitive, language, motor and social-emotional domains
|
At 6, 12, and 24 months of age

|
During pregnancy (each trimester) and at birth (cord blood)
|
|
Gut microbiota composition
Tidsramme: During pregnancy (each trimester), at birth (meconium), and at 4, 6, 12, and 24 months of age
|
Gut microbiota composition will be analyzed using 16S rRNA gene sequencing and reported as relative abundance and diversity indices
|
During pregnancy (each trimester), at birth (meconium), and at 4, 6, 12, and 24 months of age
|
|
Genetic polymorphisms related to methyl metabolism
Tidsramme: During pregnancy
|
Genetic polymorphisms (e.g., MTHFR, PEMT) will be assessed using genotyping methods and reported as genotype frequencies (%)
|
During pregnancy
|
|
Expression levels of neurodevelopment-related genes
Tidsramme: During pregnancy (each trimester) and at birth (cord blood)
|
Gene expression levels will be measured using RT-qPCR and report as relative expression levels

Dietary intake and diet quality
Tidsramme: From enrollment through pregnancy to 4 months postpartum
|
Dietary intake will be assessed using a Food Frequency Questionnaire (FFQ) and 3-day dietary records, including assessment of nutrient intake (grams/day ,mg/day)and dietary patterns.
Diet quality will be derived from these data
|
From enrollment through pregnancy to 4 months postpartum
