Summary
Internationally adopted children often have nutrient deficiencies, particularly iron and zinc, impacting brain development. Monitoring and addressing these deficiencies early is crucial for better neurodevelopmental outcomes.
Area of Science:
- Nutritional science
- Developmental pediatrics
- Global child health
Background:
- Internationally adopted children may face nutritional challenges due to varied global origins.
- Early childhood is a critical period for brain development, highly sensitive to nutrient status.
Purpose of the Study:
- To evaluate nutrient status in internationally adopted infants from diverse regions.
- To investigate the association between nutrient deficiencies and neurodevelopmental outcomes.
Main Methods:
- Recruited internationally adopted infants (8-18 months) from Post-Soviet States, Ethiopia, and China.
- Conducted comprehensive nutritional and neurodevelopmental assessments at baseline and 6-month follow-up.
Main Results:
- High prevalence of stunting (35%) and abnormal nutrient markers (68%) at baseline.
- Common deficiencies included low retinol-binding protein, zinc, vitamin D, and iron.
- Iron and zinc deficiencies were linked to poorer cognitive scores, processing speed, and memory.
Conclusions:
- Early nutrient deficiencies are prevalent in internationally adopted infants.
- Iron and zinc deficiencies correlate with impaired neurodevelopment.
- Routine micronutrient monitoring is essential for adopted children upon arrival and during early follow-up.

1.1K
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

1.1K
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

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.

01:10Nature and Nurture
22.8K
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,...

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
