1. What is Corrected Gestational Age?

Corrected gestational age accounts for prematurity by adjusting the infant's age based on how early they were born. It provides a more accurate assessment of developmental expectations for premature infants.

2. How Does the Calculator Work?

The calculator uses the corrected age formula:

Where:

• \( \text{Gestational Age} \) — Current age since conception (weeks)
• \( \text{Weeks at Birth} \) — Weeks of gestation at time of birth

Explanation: The formula adjusts for the weeks of prematurity by comparing the birth week to full term (40 weeks).

3. Importance of Corrected Age

Details: Corrected age is crucial for assessing developmental milestones, growth patterns, and medical needs in premature infants. It helps avoid inappropriate comparisons with full-term infants.

4. Using the Calculator

Tips: Enter the current gestational age (since conception) and the gestational age at birth (weeks). Both values should be between 20-45 weeks.

5. Frequently Asked Questions (FAQ)

Q1: Until what age should corrected age be used?
A: Typically until 2-3 years old, though this varies by individual and developmental domain.

Q2: What's the difference between chronological and corrected age?
A: Chronological age is time since birth, while corrected age accounts for prematurity.

Q3: How does this affect developmental milestones?
A: Premature infants often reach milestones closer to their corrected age than chronological age.

Q4: When should I stop using corrected age?
A: Most experts recommend phasing out corrected age between 18-36 months, depending on the child's progress.

Q5: Does this affect vaccination schedules?
A: No, vaccinations should be given based on chronological age, not corrected age.
