• ‘Point-of-care’ food fortification with MNP a novel
alternative to daily supplementation for delivering iron
and other micronutrients with foods
• Variability in the formulation of MNP, target age group,
and settings or context
• Early brain development is also sensitive to built
environment and services.
• Integrating nutrition with child development interventions
may lead to synergistic effects on early child development
that are stronger than single sector interventions.
• India provides an integrated nutrition/child development
(preschool) services through government-sponsored
Integrated Child Development Services.
Rationale
To examines whether preschool-delivered, multiple micronutrient
powder (MNP) fortified meals vs. placebo impact child development
and whether effects vary by preschool quality.
Hypotheses:
The MNP leads to better MN status, development, and growth,
compared to placebo
High Quality AWC s are associated with better development than
Low Quality AWCs.
The effect of the MNP on preschoolers’ development varies by the
quality of the AWC, with stronger effects in High Quality AWCs.
Objectives
Study design:
A cluster randomized, double masked, controlled trial of
MNP/placebo powders nested within low-/high-quality preschools.
Sample size of 76/group, clustered in 22 preschools for moderate
effect size on child development (0.5 SD).

Conclusions
Adding MNP fortification to preschool meals reduces rates of anemia
and iron deficiency, and reduces disparities in language, inhibitory
control and parent-reported behavior associated with preschool
quality.
Scaling MNP meal fortification and improving preschool quality can
enhance preschoolers’ development and reduce disparities.
