 The International Atomic Energy Agency IAEA has reviewed published literature to collect information for its Coordinated Research Project CRP on Zinc Nutrition During Early Life , and observed that there is limited information on: 1 the concentration of zinc in breast milk of mothers in lower income countries at different times post-partum; 2 the total amount of zinc transferred from mothers to infants at different ages in these settings, and 3 zinc transfer from mother to infant born with appropriate-for-gestational-age AGA and small-for-gestational-age SGA. Therefore, IAEA has planned to assist local scientists to collect such information from selected countries. The International Zinc Nutrition Consultative Group IZiNCG has identified Bangladesh as a country with high risk of zinc deficiency IZiNCG, 2004, where the rate of SGA infants is 30 - one of the highest in the world de Onis, 1998. Thus, Bangladesh is an appropriate candidate country to participate in this CRP.
