Brief summary

The objective of the study is to evaluate the impact of the milk-based nutrient-rich bar, specifically the effect of its fortification with zinc, iodine, vitamins A and D and calcium on nutritional status of school children, focusing on vitamin A and, zinc, iodine, calcium and iron status, and on their cognitive performances.

Detailed description

Design: double-masked randomized control trial Place: three schools in South Vietnam, Can Tho district, South Vietnam Subjects: School children aged 6 to 10 years old, from first grade to third grade of 3 primary schools. Duration of intervention: 6 months (consumption of Goody or control bar) Study groups: 2 groups: Group 1: children will receive micronutrient enriched milk bar. Group 2: children will receive the same milk-based food except for the micronutrient fortification.

Primary

Measure	Time frame	Description
micronutrient status	6 months intervention study with baseline and endpoint data collection	change in micronutrient status (hemoglobin and serum concentrations of vitamin D, calium, zinc) from baseline to end of the intervention when children have received the food bar for 6 months, 5 days/week.
