Condition(s) targeted: Vitamin A Deficiency; Iron Deficiency; Zinc Deficiency
Intervention: fortified extruded rice (Dietary Supplement)
Phase: Phase 0
Status: Completed

Summary
Iron, zinc and vitamin A deficiencies are particularly common among children and young women
in the developing countries of South and Southeast Asia resulting in important adverse
health effects. Simultaneous fortification of rice with iron, zinc and vitamin A could be a
novel and sustainable approach to control these deficiencies.
Recently conducted extrusion trials have demonstrated that extruded rice grains containing
iron, zinc and vitamin A show acceptable stability during production and storage and good
sensory properties. The grains were produced using a twin-screw extruder equipped with a
special cutter and a rice shaping die. The Fe, Zn and vitamin A content of the extruded
product is 10 mg, 9 mg and 1050 μg per g of rice, respectively.
In this study the investigators plan to test the efficacy of the extruded triple fortified
rice in Satun, Thailand, an area where rice is the staple food. Preliminary data from this
area show that zinc and vitamin A intakes are low. Biochemical indicators have confirmed
zinc deficiency and suboptimal vitamin A status in 1/3 of school aged children. The efficacy
of the fortified rice will be evaluated in a 9 months, controlled, double-blind intervention
trial in 7-12 y-old children. Children will be selected from primary schools in Satun
Province based on low serum zinc values as the primary goal is to investigate Zn efficacy.
As secondary outcome the effect on iron and vitamin A status will be investigated. The
children will be randomized into two groups: a control group will receive a daily
non-fortified rice lunch meal at school, while the second group will receive a daily rice
meal containing the triple fortified rice. The rice meals will be given 5 days a week. At
baseline, weight and height will be measured and determination of hemoglobin, serum
ferritin, zinc protoporphyrin, serum zinc, serum retinol and C-reactive protein will be
done. At mid-point and at 9 months, the baseline measurements will be repeated to judge the
efficacy of the triple fortified rice.
