AnthroPed

Accurate calculation of Z-score and Percentiles, by days of life according to WHO, Cerebral Palsy Growth Charts, Down syndrome, Neonates(Fenton, Olsen, INTERGROWTH-21st)

This application calculates and graphically displays the Z-Score and percentile of the main anthropometric indicators across the entire pediatric age range. It also performs a detailed analysis of growth velocity, using days of life as the reference. It was developed and programmed by Gerson Rodríguez, Pediatric Specialist.

Main Features

1. Percentile and Z-Score Charts and Calculations (WHO / CDC): Charts and calculations based on WHO and CDC standards, with day-of-life sensitivity, to ensure accurate growth assessment for: Weight / Length Weight / Age Length (Height) / Age BMI / Age Head Circumference / Age
2. Growth Velocity Analysis: Evaluates changes in length, weight, or head circumference, displaying Z-scores, percentiles, and graphs that highlight progress between visits. 2.1 Quantitative deficit or excess analysis: For each indicator, the app calculates the exact difference between the child and each standard deviation curve (–3 to +3 SD).
3. Cerebral Palsy Growth Charts Includes weight, height, and BMI charts for children with Cerebral Palsy, stratified by the Gross Motor Function Classification System (GMFCS I–V), with Level V divided into tube-fed (TF) and non-tube-fed (NT). Based on: Jordan Brooks et al., Pediatrics 128(2): e299–e307.
4. Daily Fluid Requirement Calculation: Calculates daily fluid needs using the Holliday & Segar method or body surface area.
5. Patient Database Management: Create and manage patient records including percentiles, Z-scores, and anthropometric measurements for comprehensive follow-up.
6. Import and Export Data: Easily import and export the patient database for flexible data management.
7. Preterm and Neonatal Growth Charts: Charts and calculations based on the latest FENTON, INTERGROWTH-21st, and OLSEN (2010) references.
8. Down Syndrome Growth Charts: Growth charts specially adapted for children with Down syndrome.

All results are based on the LMS model (Cox distribution: Lambda – Mu – Sigma), applied to height, weight, BMI, and head circumference.
