GFDx

GFDx assesses folic acid and iron food fortification coverage and projects maternal and child health impacts in low- and middle-income countries (LMICs) using data from the Global Fortification Data Exchange.

Key Features:

• Data Integration: Integrates data from the Global Fortification Data Exchange, including indicators such as food intake, fortification standards, and the percentage of industrially milled food that is fortified.
• Coverage Estimation: Calculates the percentage of women of reproductive age (WRA) receiving recommended dietary allowances through fortification as an estimate of fortification coverage.
• Health Impact Analysis: Uses the Lives Saved Tool (LiST) to estimate outcomes such as averted cases of anemia among WRA and reductions in stillbirths and neonatal deaths due to neural tube defects.
• Geographical Insights: Provides coverage data for folic acid fortification across 72 countries and iron fortification across 87 countries, highlighting disparities between higher-income countries and LMICs.
• Trend Analysis: Includes trends in fortification coverage as new data become available to assess program effectiveness over time.

Scientific Applications:

• Public Health Interventions: Estimates the impact of folic acid and iron fortification on maternal anemia and neural tube defect–related outcomes to inform intervention strategies.
• Policy Development: Supports assessment of current fortification programs to identify areas for improving coverage and effectiveness.
• Research and Monitoring: Enables monitoring of fortification trends, evaluation of interventions, and guidance for studies on nutritional deficiencies.

Methodology:

Combines data from multiple sources, calculates fortification coverage based on dietary intake and industrial milling practices, and projects health impacts using the Lives Saved Tool (LiST).
