IV. Growth Failure in Institutionalized Children.
Monographs of the Society for Research in Child Development
|November 4, 2014
Summary
Institutionalized children often experience growth suppression due to nutritional issues and social deprivation. Early intervention in nurturing environments promotes catch-up growth, benefiting cognitive development and reducing long-term health risks.
Area of Science:
- Pediatric Endocrinology
- Developmental Psychology
- Child Health
Background:
- Children in institutional care frequently exhibit global growth suppression.
- This growth impairment is more severe in vulnerable populations like low birth weight infants or those with prenatal alcohol exposure.
- Psychosocial deprivation and nutritional insufficiencies are key contributors to growth failure in these settings.
Purpose of the Study:
- To explore the etiology and consequences of psychosocial growth failure in institutionalized children.
- To understand the factors influencing catch-up growth and final height.
- To investigate the long-term health implications, including cognitive and metabolic outcomes.
Main Methods:
- The study synthesizes existing research on growth patterns in institutionalized children.
- It examines the interplay of nutritional status, the growth hormone-insulin-like growth factor 1 (GH-IGF-1) axis, and social environment.
- Analysis considers age-related differences in growth recovery and potential long-term sequelae.
Main Results:
- Catch-up growth is rapid in nurturing environments, positively correlated with caregiver sensitivity.
- Younger children show the greatest potential for growth recovery.
- Growth recovery is linked to cognitive recovery, but persistent neuroendocrine abnormalities and micronutrient deficiencies may still impact development.
Conclusions:
- Early psychosocial deprivation significantly impacts child growth and development, with potential lifelong consequences.
- Nurturing environments are crucial for optimizing catch-up growth and cognitive recovery.
- Institutionalized children, especially those with early growth restriction, may face increased risks for metabolic syndrome in adulthood.

19.3K
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,...

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

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...

Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...
