A new method for maturity determination in newborn infants.

Area of Science:

• Neonatal Medicine
• Pediatrics
• Clinical Assessment

Background:

• Accurate gestational age assessment is crucial for neonatal care.
• Existing methods for maturity determination can be complex or less accurate in specific populations.

Purpose of the Study:

• To develop and evaluate a simple, accurate method for maturity determination in newborn infants in Nigeria.
• To create a clinical tool for assessing both healthy and sick neonates.

Main Methods:

• A six-feature model was developed using head circumference, mid-arm circumference, skin texture, ear form, breast size, and genitalia.
• Gestational age correlation was established using regression analysis.
• The model's accuracy was compared against the Dubowitz method and a previously reported abbreviated method.

Main Results:

• The six-feature model demonstrated a highly significant correlation with gestational age.
• The model showed comparable accuracy to the Dubowitz method.
• It reliably identified subgroups of term and low-birth weight infants and was more accurate for sick neonates than a prior abbreviated method.

Conclusions:

• The developed six-feature model offers a simple, rapid, and reliable tool for maturity determination in newborn infants.
• This method is suitable for clinical application in both healthy and sick neonates.
• It provides an effective alternative for gestational age assessment in the studied population.
