Designing new growth charts for low-birth weight babies: need of the hour in India

Area of Science:

• Pediatrics
• Neonatology
• Public Health

Background:

• Unplanned catch-up growth in low birth weight (LBW) infants is linked to adult non-communicable diseases (NCDs).
• Current World Health Organization (WHO) growth charts, designed for healthy, breastfed infants, may not be suitable for LBW or small for gestational age (SGA) babies.
• Existing protein-energy malnutrition (PEM) diagnostic criteria lack birth weight consideration, potentially misclassifying LBW infants.

Purpose of the Study:

• To question the applicability of current WHO growth standards for LBW and SGA infants.
• To highlight the potential risks of current PEM diagnostic criteria and catch-up growth management in LBW infants.
• To advocate for the development of standardized growth charts specifically for LBW babies.

Main Methods:

• Literature review on theories linking infant growth patterns to adult NCDs.
• Analysis of current diagnostic criteria for PEM and growth monitoring standards.
• Conceptual evaluation of the long-term health implications for LBW infants managed with standard growth protocols.

Main Results:

• LBW infants growing within their initial centiles may be incorrectly diagnosed with PEM.
• Encouraging excessive caloric intake for weight gain can lead to "crossing the percentile," potentially increasing future NCD risks.
• Current management strategies may inadvertently expose LBW infants to long-term health risks.

Conclusions:

• Standard WHO growth charts may not accurately reflect optimal growth trajectories for LBW infants.
• A revision of growth monitoring guidelines is necessary for LBW babies.
• Separate, standardized growth charts for LBW infants are needed to ensure appropriate growth and mitigate future NCD risks.
