Abstract
Objectives: Iodine deficiencies compromise the health and the development of many school-age
children worldwide. The aim of this study was to determine the efficacy of iodine fortified milk
consumption among Moroccan schoolchildren (n = 193) in rural region.
Methods: Iodine status was assessed in 79 children aged 7–9 y before and after consumption of
200mL UHT fortified milk (providing 30% RDA for iodine) daily for 9-months compared to a control
group (n = 114) who consumed non-fortified milk. Anthropometric measurements and urine
samples were collected and analysed at baseline, 4 months (T4) and 9 months (T9).
Results: Severe iodine deficiency was prevalent among the intervention group. At T4 and
T9, there was a marked improvement of severe iodine deficiency in the fortified group (8.9% at the
baseline, 1.4% at T4 and 0% at T9). The prevalence of moderate iodine deficiency was reduced
from the baseline to the end of the study ranging from 36.8% to 6.4%. While for the mild iodine
deficiency, the prevalence was increased at T4 (61.9%) and then decreased at T9 (23.6%). A
significant reduction of the prevalence of iodine deficiency was observed in the control group certainly due to the presence of residual iodine in the whole non fortified milk (10.4μg/100ml).
Conclusions: The consumption of iodine fortified milk led to a clear improvement of iodine status
among schoolchildren of rural.
This study was performed with the support of "Fondation Centrale Laitière pour la Nutrition de
l'Enfant".
