Simulated effects of home fortification of complementary foods with micronutrient powders on risk of inadequate and excessive intakes in West Gojjam Ethiopia.

Home fortification of complementary foods (CFs) with multiple micronutrient powders (MNPs) is being scaled up in various countries but little is known about the prevailing complementary feeding practices and the type and nutrient gaps to be filled with MNPs. The present study evaluated the complementary feeding practices of young children and simulated the risk of inadequate and excessive intakes associated with home fortification with MNPs. We have assessed the sociodemographic status anthropometry and complementary feeding practices of young children (N = 122) in Mecha district rural Ethiopia. Using a 2-day quantitative 24-hr recall usual intakes of energy protein iron zinc and calcium were estimated. The risks of inadequate and excessive iron and zinc intakes with or without home fortification scenarios were assessed. The simulations considered intakes from CFs assuming average breast milk contributions and additional nutrients provided by the MNPs. Stunting was highly prevalent (50%) and was associated with a lower dietary diversity (P = .009) and nutrient intakes from the CFs. Median energy zinc and calcium intakes were below the estimated needs from CFs; protein needs were met. Median dietary iron intake appeared adequate but 76% 95% CI [68% 84%] of children had inadequate intake (assuming low bioavailability) whereas another 8% 95% CI: [3% 13%] had excessive intakes. Simulation of daily and alternative days fortification with MNP decreased the prevalence of inadequate iron and zinc intake but significantly increased the risk of excessive intakes that remained unacceptably high for iron (>2.5%). Untargeted MNP interventions may lead to excessive intakes even in settings where poor complementary feeding practices are prevalent.
