Summary
This study developed and applied a mathematical modelling framework to assess how large-scale food fortification of oil, sugar, and wheat flour could contribute to micronutrient adequacy in Malawi using Household Consumption and Expenditure Survey data. The analysis found that oil and sugar fortification, when combined, could meaningfully reduce vitamin A inadequacy, but wheat flour contributed minimally due to low consumption. Crucially, the model predicted that fortification interventions would have limited impact on rural populations of lowest socioeconomic status, indicating that fortification alone is insufficient to address micronutrient deficiencies in the poorest segments of the population.
UK applicability
This study's findings on equity gaps in food fortification effectiveness have limited direct application to the United Kingdom, where food fortification is already regulated and dietary micronutrient deficiencies are less prevalent. However, the mathematical modelling framework and approach to evaluating fortification vehicles across socioeconomic subgroups may inform UK policy discussions on food security and nutritional inequality.
Key measures
Fortification vehicle coverage; micronutrient density of diet; apparent intake of nine micronutrients; vitamin A adequacy ratios; stratified analysis by socioeconomic position and rural/urban setting
Outcomes reported
The study modelled the potential contributions of three fortification vehicles (oil, sugar, wheat flour) to meeting dietary micronutrient requirements in Malawi using household consumption data. It estimated fortification coverage, micronutrient density, and apparent micronutrient intake across subpopulations and seasons for nine micronutrients.
