Abstract

Abstract Objectives Our objectives were to estimate apparent intake of iron in Haiti, to assess the adequacy of iron intake among women of reproductive age (WRA), and to model the cost-effectiveness of fortifying alternative food vehicles for reducing inadequate intake. Methods We analyzed the most recent Haiti household food consumption data (2012 ECVMAS) to estimate adequacy of apparent iron intake from dietary sources (using the adult male equivalent method; assuming 10% absorption) and modeled the impacts of fortifying currently mandated (wheat flour, applying local data on current compliance) and hypothetical (bouillon and rice) food vehicles on reductions in the prevalence of inadequate iron intake (effective coverage). We built activity-based cost models to estimate large scale food fortification (LSFF) program establishment and management costs, based on key informant interviews and on published cost estimates from other settings adapted to fit the Haitian case. Results The prevalence of inadequate dietary intake of iron among WRA was 79% (100% among pregnant women). Iron-fortified wheat flour was the most cost-effective vehicle: $4.32 and $4.75 per WRA-year effectively covered at current (75% of flour fortified to the standard of 30 mg/kg) and target (90% fortified to the standard) fortification levels. Fortified wheat flour effectively covered 11–13% of non-pregnant WRA, but almost no pregnant women. Although bouillon was consumed by > 98% of households, low estimated iron absorption from fortified bouillon (2%) led to low effective coverage. Iron-fortified rice (90% fortified at 120 mg/kg) was predicted to effectively cover the largest number of WRA (reducing inadequate intake to ∼30%), but at a cost of $7.80 per WRA-year effectively covered. Conclusions Of the food vehicles modeled, wheat flour was the most cost-effective for reducing inadequate iron intake. Modeling iron fortification of individual and combinations of food vehicles showed that well-designed LSFF programs can contribute to improving iron status among non-pregnant women, but eliminating inadequate iron intake among all WRA will require complementary iron interventions.
