Influence of complex childhood diseases on variation in growth and skeletal development

Area of Science:

• Human biology
• Evolutionary biology
• Pediatric health

Background:

• Human growth and skeletal development studies inform understanding of population variation and evolution.
• Assessing child health, well-being, and creating growth charts benefit from this perspective.
• Environmental, behavioral, and disease factors can impede genetic growth potential.

Purpose of the Study:

• To explore how health and disease impact human growth and skeletal development.
• To examine the role of undernutrition and specific diseases on growth faltering.
• To discuss the utility and controversy of syndrome-specific growth charts.

Main Methods:

• Literature review and synthesis of existing research on human growth.
• Illustrative examples from conditions like cystic fibrosis, inflammatory bowel disease, Down syndrome, Alagille syndrome.
• Analysis of the plasticity and sensitivity of human growth to health status.

Main Results:

• Undernutrition is a primary cause of growth faltering and poor skeletal development.
• Diseases such as cystic fibrosis, inflammatory bowel disease, and Down syndrome significantly affect growth.
• Syndrome-specific growth charts offer advantages but also limitations, particularly for children with genetic disorders.

Conclusions:

• Human growth is highly plastic and sensitive to overall health and well-being.
• Understanding these influences is crucial for individual and group-level child health assessment.
• The use of syndrome-specific growth charts requires careful consideration of associated medical and nutritional factors.
