TRIAL DESCRIPTION
Public title Efficacy study of the consumption of milk fortified in vitamins and minerals
Official scientific title Efficiency study of iodine fortification of milk on iodine status markers: A longitudinal interventional non randomized, controlled study among school children in Morocco
Brief summary describing the background and objectives of the trial Abstract Background: Iodine deficiency is prevalent worldwide and can affect growth, mental development and learning ability of school children. In line with the Moroccan National Strategy for Nutrition 2011¿2019, we undertook a study to evaluate the efficiency of the consumption of iodine fortified milk on iodine status of children living in rural region. Methods: The study is a longitudinal, interventional double-blinded, placebo controlled one concerning 191 children, aged 7 to 9 years, recruited from 3 schools in a rural, high altitude province in Morocco. The sample was divided in two groups: a non-fortified milk group (NFM, n=103) received 200ml of non-fortified Ultra High Temperature (UHT) milk and a fortified milk group (FM, n=50) received 200ml UHT milk fortified with iodine persulfate to cover 30% of Recommended Daily Intake. Urine samples were collected at baseline, 4th and 9th months and urinary iodine was determined spectrophotometrically using the Sandell-Kolthoff reaction. All statistical analyses were performed using Statistical Package for the Social Sciences (version 17.0).

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome Data analysis clearly demonstrated the amelioration of iodine status in fortified and non-fortified milk groups. Severe and mild iodine deficiencies were reduced for both groups. Moreover, there¿s complete disappearance of severe deficient cases in the fortified milk group after 4 months of intervention. January 2013
Secondary Outcome ongoing ongoing
Primary Outcome The prevalence of vitamin A deficiency for the fortified group dropped from 50% at baseline to 4.3% at end line compared to non-fortified group where it dropped from 44% to 24.8%. The difference between both groups was highly significant (p<0.0001). January 2013
Primary Outcome Results of the fortified group showed that the prevalence of iron deficiency anemia (IDA) dropped from 1.8% at baseline to 0% at endline and prevalence of iron deficiency (ID) dropped significantly from 50.9% to 37.2% (p=0.037) compared to the non-fortified group where prevalences remained stable for both IDA and ID.
