For each of the primary outcomes, stunting, micronutrient intake, dietary diversity score, and academic performance of children, the difference in mean change at follow-up between intervention and control arms will be compared. The hypotheses will be tested under the intent-to-treat principle using Generalized Linear Mixed Models (GLMMs) that will account for the correlation induced by the clustering of children within schools. To further explore the effect of the intervention, GLMMs will be fit that (1) adjust for baseline covariates of interest, consider a priori, relevant to change in nutritional status, KAP of micronutrient deficiencies prevention, micronutrient intake and dietary diversity score; (2) adjust for baseline variables distribute differently between intervention groups; (3) test interaction terms between treatment group and other covariates; and (4) examine completers only. Differences in the secondary outcomes, underweight and obesity will be analyzed in a parallel fashion. Mediating and moderating effects of the factors mentioned above will also be explored.
