Feeding India - Child Growth Monitor

A modern web application for monitoring and analyzing children's growth patterns using WHO standards. Built with Next.js, React, Supabase, and TailwindCSS.

Features

• Dashboard: Real-time overview of growth metrics and trends
• Program Management: Track multiple health programs and interventions
• Growth Analysis:
  • Population Analysis
  • Growth Trends
  • Intervention Impact
• Data Visualization:
  • WHO Standard Growth Charts
  • Height-for-Age Analysis
  • Weight-for-Age Analysis
• Data Management:
  • Individual Child Records
  • Batch Upload Functionality
  • Data Entry Forms
• Documentation: Comprehensive guides on WHO standards and metrics

Growth Assessment Methods

Height/Length Measurement

For Children Under 2 Years

• Recumbent Length: Measured lying down
• Required Equipment: Length board with fixed headpiece and movable footpiece
• Precision: Measurements recorded to nearest 0.1 cm
• Two people required for accurate measurement

For Children 2 Years and Older

• Standing Height: Measured standing upright
• Required Equipment: Stadiometer or height board
• Precision: Measurements recorded to nearest 0.1 cm
• Child should stand with:
  • Heels together
  • Shoulders level
  • Head in Frankfurt plane position

Weight Measurement

• Equipment: Electronic scale with 0.1 kg precision
• Procedure:
  • Zero scale before each measurement
  • Child wearing light clothing only
  • Record to nearest 0.1 kg

Growth Standards Reference

We use the WHO Child Growth Standards (0-5 years) and WHO Growth Reference (5-19 years):

Key Indicators

• Length/height-for-age
• Weight-for-age
• Weight-for-length/height
• Body mass index (BMI)-for-age

Z-Score Classifications

• Above 3: Severely high
• Above 2: High
• 0: Median
• Below -2: Low
• Below -3: Severely low

Technical Implementation

Growth Chart Calculations

interface GrowthData {
  age: number;        // Age in months
  measurement: number; // Height or weight
  zscore: number;     // Standard deviation from median
}

// Z-score calculation
const calculateZScore = (measurement: number, median: number, sd: number): number => {
  return (measurement - median) / sd;
};

// Growth velocity calculation (cm/month)
const calculateGrowthVelocity = (
  currentHeight: number,
  previousHeight: number,
  monthsDifference: number
): number => {
  return (currentHeight - previousHeight) / monthsDifference;
};

WHO Data Integration

We use the following WHO growth chart data:

• who-growth-standards.json: Contains median and SD values for different ages
• Growth charts are generated using react-chartjs-2
• Data is interpolated for precise age-based calculations
