This is the protocol for a review and there is no abstract. The objectives are as follows:
To assess the effects of point-of-use fortification of foods with micronutrient powders containing iron alone or in combination with other vitamins and minerals on nutrition, health and development among children of preschool and school age (24 months to 12 years old) compared with no intervention, a placebo or iron-containing supplements.
For the purpose of this review, point-of-use fortification of foods with micronutrient powders refers to the addition of iron alone or in combination with other vitamins and minerals in powder form to energy-containing foods (that may or may not be in semi-solid form) at home or in any other place where meals are to be consumed, such as schools, nurseries and refugee camps. Micronutrient powders can be added to foods either during or after cooking or immediately before consumption without the explicit purpose of improving the flavour.
