Book Description
This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Book Description
Iron deficiency (ID) is the most prevalent single nutrient deficiency in the world and 50% of anemia is due to ID. Mothers and children under the age of five, especially those from middle- and low-income settings, are the most affected by the deficiency. The consequences of the deficiency are known to impact both pregnant and non-pregnant women at the physical and psychosocial level. In children, ID is known to be a risk factor for inadequate development. The objective of this study was to explore the effects of six months of iron supplementation in infants between six to 18 months old on mother-infant interactions in a rural Bangladeshi sample. The data used for the current analysis are from a substudy of a larger longitudinal randomized, double-blind, placebo-controlled factorial community trial exploring the effects of iron and zinc on diarrhea and anemia outcomes. Infants were supplemented for six months with iron/folic acid (n=70), iron/folic acid and zinc given either in combination (n=70) or separately (alternating days; n=73), and placebo (n=69). In this substudy, mother-infant interaction was measured at baseline (n=91), midpoint (three months; n=263), and endpoint (six months; n=272). Iron status was assessed in both, mothers and infants at baseline and endpoint via serum ferritin, transferrin receptor, C-reactive protein, and hemoglobin (in the infants only). Mother-infant interactions were coded per the Emotional Availability Scales comprised of four maternal scales: sensitivity, structuring, non-intrusiveness, and non-hostility and two infant scales: responsiveness and involvement. Other measurements collected and which were related to mother-infant interactions include: socioeconomic status, mean upper arm circumference, weight-for-age Z score, childs sex and age, maternal depressive symptoms and maternal reasoning ability. At baseline, there were no demographic differences between supplementation groups but maternal transferrin receptor and body iron levels differed by groups. Post six months of supplementation to infants, infants differed significantly among groups in iron status while mothers did not. Cross-sectional analyses indicated that there were no differences between groups on scores of the emotional availability subscales at any time point. Longitudinal analyses indicated that scores at endpoint on the subscales (all except child scales) decreased compared to baseline regardless of supplement type and the magnitude of change did not differ between groups. These findings indicate that mother-infant interactions in this sample were not affected by supplement type, but other factors were important. Positive contributors to the outcome were higher maternal reasoning ability, higher maternal and infant iron status, increased days of breastfeeding, infants older age, and higher socio-economic status. Future analyses on these data will investigate the relation between infant and maternal iron status and mother-infant interactions irrespective of the supplementation groups. Considering the importance of mother-infant interactions on child development in our societies, future studies and policy makers should consider taking into account the aforementioned contributors with the hope that the well-being of mothers and infants could be improved.

Book Description
Pregnant adolescents are at risk of anemia and iron deficiency (ID). Iron stores may be compromised in newborns born to women with ID, which is of concern given the importance of neonatal iron acquisition for neurodevelopment. This study was undertaken in 255 pregnant adolescents ([LESS-THAN OR EQUAL TO] 18 y) receiving prenatal care at the Rochester Adolescent Maternity Program (2006 - 2012). We characterized maternal dietary intake, prenatal supplement use; assessed maternal and neonatal iron status; and examined the impact of neonatal iron endowment on neurophysiological function at birth. Dietary intakes of iron, magnesium, calcium, vitamins D and E did not meet the EAR in more than 70% of teens surveyed, with calcium and magnesium being the nutrients with the greatest dietary deficits. Approximately half of the adolescents selfreported daily use of prenatal supplements, however the additional supplement contribution was insufficient to bridge the dietary deficit for the EAR for magnesium and calcium. From ~26 weeks gestation to delivery, the prevalence of maternal anemia (8.6% to 19%) and ID (sTfR> 8.5 mg/L; 7% to 14%) increased significantly. Elevated concentrations of ferritin and hepcidin were observed at delivery compared to mid-gestation, due to inflammation. Maternal EPO concentrations were significantly associated with indicators of maternal iron insufficiency and with low maternal hemoglobin concentration across pregnancy, and one benefit to this indicator was that EPO was not significantly associated with inflammation across gestation. Of concern, fully 1/4 of the newborns (n=193) were anemic or had low iron stores, respectively at birth. Of interest, cord ferritin did not significantly increase with gestational age across the final 6 weeks of pregnancy (37 - 42 weeks of gestation). Maternal iron stores impacted neonatal iron stores as neonates born to mothers with ferritin

Book Description
There is a critical need for iron intake during the first period of life. The growing infant requires iron to synthesize hemoglobin and to supply expanding tissues with iron-containing enzymes. A lack of iron will eventually lead to iron deficiency anemia, one of the most common single nutrient deficiencies in the world. Today, detailed information has increased our understanding of iron bioavailability from different dietary sources, uptake mechanisms of iron into the small intestinal mucosa for transport to hepatocytes and erythropoietic cells and subsequent receptor mediated cellular acquisition. Metabolic effects of iron deficiency have also been investigated in several tissues. This comprehensive text integrates recent information and address it from a nutritional perspective. It takes this focus because of the increased knowledge on the interrelationship between iron and other essential nutrients. Specific problems of iron nutriture and oxidant stress in prematurely born infants are also addressed in this informative new text
