2、 after birth Prenatal maternal nutritional status affects birth weight neonatal morbidity and mortality and the micronutrient status of newborns while postnatal maternal status can affect the quality of breast milk and thus the nutrient intake of infants 1 2 Micronutrient defi ciencies are still a m
3、ajor public health problem in many developing countries with pregnant women and infants especially at risk 2 4 Pregnant women are particularly vulnerable to nutritional defi ciencies because of the increased metabolic demands imposed by pregnancy involving a growing placenta fetus and maternal tissu
4、es coupled with associated dietary risks 5 There are several biological strategies that impose on the mineral status of the mother for meeting the extra demands that pregnancy and lactation 6 Infants warrant extra concern because they require extra micronutrients to main tain optimal growth and deve
5、lopment 2 Most public health and nutrition programs focus on one micro nutrient only whereas several micronutrients can be expected to be defi cient at the same time 2 Micronutrient defi ciencies tend to coexist in impoverished settings because of uniformly low consumption of foods rich in multiple
6、micronutrients 7 Iron defi ciency is the most important cause of nutritional anemia and is the most common micronutrient defi ciency worldwide especi ally in developing countries 2 8 The competing demands of mother and fetus may disturb the normal maternal fetal iron homeostasis 9 11 Exclusive breas
7、tfeeding is considered adequate to meet the nutrient needs of normal term infants for approximately the fi rst 6 months of life 12 13 The micronutrient composition of human milk is generally considered to be more resistant to differences in maternal dietary intake 13 however there is considerable in
