Associations between deficiencies and child gender, birth order and household socio-economic characteristics as well as supplementation patterns were determined using chi-square tests.  Results: Approximately 39.3 percent of infants were anaemic, 23.1 percent were iron deficient (ID) and 38 percent were zinc deficient while 3.3 and 1.4 percent of infants were marginally vitamin A deficient (VAD) and vitamin D deficient (VDD), respectively.  Mean zinc concentrations were greater among iron-deficient infants compared to non iron deficient infants.  A greater proportion of ID was found among children who were not supplemented with iron, vitamin A, or vitamin D compared to supplemented children while marginal VDD is more prevalent in the group not receiving zinc supplements. Conclusions:  These findings emphasize the importance of assessing new forms of supplement which combine multiple micronutrients into a single delivery mechanism. Such supplements may more effectively reduce micronutrient deficiencies among young Iranian children.   https://jnsd.tums.ac.ir/index.php/jnsd/article/view/161
