Summary

The hypotheses of this study are:

1. Compared to children who received a placebo, children who received iron or zinc or iron and zinc combined will perform better on cognitive tests and will have better growth status at ages 8 to 10 years.
2. Compared to children who received iron or zinc alone, children who received iron and zinc combined will perform differently on cognitive tests and will have different growth status at 8 ages 8 to 10 years
3. Compared to children who had poorer iron and zinc status or poorer growth status before and after supplementation during infancy, children who had better iron and zinc status or better growth status before and after supplementation during infancy will perform better on cognitive tests and will have better growth status at ages 8 to 10 years.
4. Compared to children who have lower iron and zinc status, poorer growth status, or low animal source intake at ages 8 to 10 years, children who have higher iron and zinc status, better growth status, or high animal source intake at ages 8 to 10 years will perform better on cognitive tests and will have better growth status.
