Fenton Growth Charts: Understanding Your Child's Premature Growth
Fenton growth charts are specialized growth charts used to assess the growth of premature infants. They provide a standard to compare a premature baby's weight, length, and head circumference against the typical growth patterns of other premature infants of the same gestational age and sex. These charts are crucial tools for healthcare professionals to monitor and manage the unique growth needs of preemies.
What are Fenton Growth Charts?
Fenton growth charts, developed by Dr. Tanis Fenton, are specific growth charts designed for preterm infants. Unlike standard growth charts which are based on full-term babies, Fenton charts are constructed using data from premature infants born between 22 and 50 weeks of gestational age. This allows for a more accurate assessment of growth in preemies as they have different growth patterns and requirements compared to full-term infants.

Why are Fenton Growth Charts Important?
Standard growth charts can be misleading when used for preterm infants because they don't account for the unique growth trajectory of preemies. Premature infants often experience rapid growth early on to catch up to their full-term peers, and standard charts might falsely suggest that a preemie is underweight or falling behind. Fenton charts provide a more accurate picture of a preemie's growth, helping healthcare providers identify potential growth problems early on and intervene appropriately.

How to Use a Fenton Growth Calculator
A Fenton growth calculator allows you to plot a premature infant's growth measurements (weight, length, and head circumference) on a Fenton growth chart. The calculator uses the infant's gestational age at birth and their current age to determine their percentile on the growth chart.
Here are the general steps involved:
1. **Gather the Data:** Collect the baby's birth weight, length, head circumference, gestational age at birth, and current weight, length, and head circumference.
2. **Enter the Data:** Input the information into a Fenton growth calculator. Many online calculators are available, often provided by hospitals or medical organizations.
3.

Interpreting the Results
The results from a Fenton growth chart will show where your baby's measurements fall within a range of percentiles. The percentile indicates how the baby's measurements compare to other premature babies of the same gestational age. For example, if a baby's weight is at the 50th percentile, it means that 50% of premature babies of the same gestational age weigh less, and 50% weigh more.

It's important to remember that these percentiles are just guidelines. Healthcare professionals will consider several factors, including the baby's overall health, medical history, and family history, when assessing growth.
FAQs About Fenton Growth Charts
### 1. What is considered a normal percentile range on a Fenton growth chart?
There is no single "normal" range. Healthy growth can occur within a wide range of percentiles. Healthcare providers typically become concerned if a baby's growth is consistently below the 10th percentile or above the 90th percentile, or if there is a significant drop in percentile over time.
### 2. How often should a preemie's growth be monitored using a Fenton growth chart?
The frequency of monitoring depends on the baby's individual needs and health status. Generally, growth is monitored more frequently in the early weeks and months after birth, gradually decreasing as the baby gets older and more stable.
### 3. Can Fenton growth charts be used for full-term babies?
No, Fenton growth charts are specifically designed for premature infants. Standard growth charts are more appropriate for full-term babies.
### 4. What if a preemie's growth is not following the Fenton growth chart curves?
If a baby's growth is not following the expected curves, it doesn't necessarily mean there's a problem. However, it's important to discuss this with a healthcare professional. They can assess the situation and determine if any intervention is needed.
### 5. Are there different Fenton growth charts for boys and girls?
Yes, Fenton growth charts are sex-specific, meaning there are separate charts for boys and girls to account for the differences in growth patterns between the sexes.
Summary
Fenton growth charts are vital tools for monitoring the growth of premature infants. They provide a more accurate assessment of growth than standard growth charts, enabling healthcare providers to identify potential problems early on and implement appropriate interventions. Utilizing these charts, and understanding how to interpret them, plays a key role in ensuring the healthy development of premature babies.
