The Physical Developmental Characterization of Children with Nutritional Deficiencies and Attributed Specific...

Area of Science:

• Pediatric Nutrition
• Public Health
• Growth and Development

Background:

• Limited research exists on the physical developmental impacts of nutritional deficiency diseases (NDDs) in Chinese children aged 1-7 years.
• Previous studies have not sufficiently clarified which specific NDD categories contribute to growth faltering.

Purpose of the Study:

• To investigate the physical developmental phenotypes of NDDs in Chinese children aged 1-7 years using anthropometric measurements.
• To identify specific NDD categories associated with growth faltering in this population.

Main Methods:

• Anthropometric data (age, height, weight) were collected from 3054 children diagnosed with NDDs.
• Data were adjusted using the skewness coefficient-median-coefficient of variation method and compared against WHO standards.
• Comparisons of specific NDD categories were made using height-for-age (HAZ), weight-for-age (WAZ), and BMI-for-age (BAZ) standardized values.

Main Results:

• Calcium, vitamin A, vitamin D, and vitamin B deficiencies were the most prevalent single NDDs.
• Protein-energy malnutrition combined with vitamin C deficiency was the most common co-occurring deficiency.
• Children with NDDs exhibited lower HAZ, WAZ, and BAZ compared to WHO standards, with WAZ showing significant differences.
• Co-morbid deficiencies, such as vitamin A and D, or calcium and C, were associated with lower WAZ.

Conclusions:

• Calcium, vitamin A, and vitamin D deficiencies are key NDDs contributing to growth issues in Chinese children.
• Growth retardation, characterized by low weight and height, is driven by single and co-morbid micronutrient deficiencies.
• Anthropometric assessment is crucial for identifying and managing NDDs and their impact on child development.
