Growth Charts for Premature Babies: Following Their Own Curve
One thing all parents have in common is worrying about their baby ’ s increase and development. Parents much ask “ Is my child on a dependable percentile ? ”
Every baby should be monitored for growth, and it is authoritative to use the right field instrument to do thus. Growth charts are standards to identify how children should grow over time. however, there are different versions available to give the rear and checkup master steering. Understanding different types of growth charts can help ease a rear ’ s mind .
Term Infant Growth Charts
The Center of Disease Control ( CDC ) and the World Health Organization ( WHO ) recommend using WHO growth charts to monitor growth for full-term infants from 0-2 years of long time. The american College of Obstetricians and Gynecologists ( ACOG ) define a term baby as bear between 37-40 weeks pregnancy .
WHO growth charts :
- Use breastfed infants as the norm for growth. Chart patterns reflect infants breastfed for at least 4 months and still breastfeeding at 12 months.
- Describe how infants should grow under optimal conditions.
- Are gender-specific.
- Include Weight, Length, Head Circumference and Weight-for-Length in monthly increments.
- Have percentile curves for each chart, as follows:2nd, 5th, 10th, 25th, 50th, 75th, 90th, 95th and 98th.
- Do not recommended using Body Mass Index (BMI) in children under 2 years of age.
Preterm Infant Growth Charts
ACOG defines a preterm baby as born at less than 37 weeks gestational age. Preterm growth charts should be used for these babies. Preterm growth charts aim to mimic increase that occurs during a term pregnancy. The Fenton preterm increase chart is used by many checkup professionals .

- Are based on birth size of over 4 million infants with confirmed gestational ages in developed countries including Germany, Italy, United States, Austria, Scotland and Canada.
- Begin at 22 weeks and end at 50 weeks.
- Should be used in conjunction with term charts after 40 weeks.
- Are gender-specific.
- Include Weight, Length and Head Circumference in weekly increments.
- Do not include Weight-for-Length or BMI.
- Include percentiles, as follows: 3rd, 10th, 50th, 90th and 97th.
Plotting the Former Preterm Infant on Term Growth Charts
WHO increase charts should be used for preterm infants who are corrected to terminus age. Corrected age is used to describe the child ’ sulfur age from the original ascribable date .
- When plotting a baby’s growth, it is recommended to use corrected age through 2 years from the original due date. Some experts recommend correcting through 3 years.
- If age is not corrected, the infant may appear to be growing suboptimally.
- Catch-up growth can occur during this 2 year period.
- Catch-up growth here refers to rapid growth of preterm infants that minimizes the size difference with term counterparts.
- Using corrected age during a period of catch-up growth provides the infant time to achieve typical growth standards.
- Rate of catch-up growth is affected by birth weight, gestational age at birth, genetic potential and medical condition.
It ’ s important to remember there are by and large no dependable or bad individual percentiles. Weight, length and headway circumference are looked at together for an overall picture. Plotting growth on multiple points over time is besides important. It is unmanageable to assess growth with only a few measurements in a brusque period of time.
ideally a child will plot on the emergence chart ( not above or below ) and continue to follow a fairly consistent and proportional ( weight like to length ) course. A checkup professional will work with each parent to assess growth and, if needed, create an individualized plan .
