Fenton 2013 iOS App, developed by Rebecca Chou
- In consultation with Joseph Chou
The Fenton 2013 preterm growth charts are based on systematic review and meta-analysis of population-based, gender-specific preterm measurements at birth of weight, length, and head circumference references from developed countries. The chart was smoothed to avoid discontinuity between the preterm datasets and the World Health Organization (WHO) Growth Standard, to promote an improved transition between preterm and WHO growth charts. This implementation uses LMS parameters (skew, median, and standard deviation) to allow calculation of precise percentiles and Z-scores.
- gender-specific, from 22 4/7 to 50 0/7 weeks gestation
- calculation of percentile and Z-scores for weight, length, and head circumference
- alert for small (less than 10th percentile) or large (greater than 90th percentile) for gestation
- displays growth needed to maintain current percentile
- convenient buttons to display 10th, 50th, and 90th percentile measurements
- slider selection to display measurement between 1st and 99th percentile
Future plans
- this is a fully functional implementation of the Fenton 2013 Preterm Growth Chart, although it does not yet include all features available in the web-based version
- however, in the future, we may add additional features including:
- integrated gestational age calculator
- support for both metric and imperial units
- long-term hope to include support for multiple pediatric growth charts in a single app
- feedback would be appreciated!
