Background Assessment for vitamin C deficiency (VCD) is rarely undertaken in an acute hospital setting in high-income countries. However, with growing interest in VCD in community settings, there is emerging evidence investigating the prevalence and impact of VCD during hospitalization. Objectives In this scoping review, the prevalence of VCD in adult hospitalized patients is explored, patient characteristics are described, and risk factors and clinical outcomes associated with VCD are identified. Methods A systematic scoping review was conducted in accordance with the PRISMA-ScR framework. The Ovid MEDLINE, Ovid Embase, Scopus, CINAHL Plus, Allied and Complementary Medicine Database, and the Cochrane Library databases were searched for interventional, comparative, and case-series studies that met eligibility criteria, including adult hospital inpatients in high-income countries, as defined by the Organization for Economic Co-operation and Development, that reported VCD prevalence using World Health Organization reference standards. These standards define VCD deficiency as plasma or serum vitamin C level <11.4 µmol/L, wholeblood level <17 µmol/L, or leukocytes <57 nmol/108 cells. Results Twenty-three articles were included, representing 22 studies. The cumulative prevalence of VCD was 27.7% (n = 2494; 95% confidence interval [CI], 21.3-34.0). High prevalence of VCD was observed in patients with severe acute illness and poor nutritional status. Scurvy was present in 48% to 62% of patients with VCD assessed in 2 studies (n = 71). Being retired (P  = 0.015) and using excessive amounts of alcohol and tobacco (P  = 0.0003) were independent risk factors for VCD (n = 184). Age was not conclusively associated with VCD (n = 631). Two studies examined nutrition associations (n = 309); results were inconsistent. Clinical outcomes for VCD included increased risk of frailty (adjusted odds ratio, 4.3; 95%CI, 1.33–13.86; P  = 0.015) and cognitive impairment (adjusted odds ratio, 2.93; 95%CI, 1.05–8.19, P  = 0.031) (n = 160). Conclusions VCD is a nutritional challenge facing the healthcare systems of high-income countries. Research focused on early identification and treatment of patients with VCD is warranted.

There has been a global increase in the older population in recent decades and, as age advances, complex metabolic and epigenetic changes occur in the organism, and these may trigger some health complications commonly found among this population. Additionally, several changes occur in older people that can reduce the dietary intake or the process of nutrient absorption. In this way, tissues with high nutrient requirements are more affected. Hematopoiesis is the process of formation, development, and maturation of blood cells and is a process with a high turnover. This high demand makes the integrity of the hematopoietic process susceptible to various factors that impair physiological function, such as aging and micronutrient bioavailability. Among these micronutrients, Zinc is considered an important micronutrient, playing diverse roles across various tissues and cell types. Some of the alterations in hematopoiesis that appear as a consequence of aging and due to insufficient micronutrient intake are well described in the literature; however, not much is known about how zinc deficiency contributes towards the development of diseases seen in aging. Considering the importance of zinc to act on several biological processes, this narrative review discusses several studies related to the physiological requirements, deficiency, or excess of zinc, including studies in experimental models and humans, and aimed to shed light on the relationship between zinc and the regulation of hematopoietic tissue, exploring possible links between this mineral with common disorders that appear during aging.

Fetal alcohol exposure can lead to a range of developmental disorders, including impaired fetal growth and development of multiple organ systems. These disorders are grouped under the term fetal alcohol spectrum disorders (FASDs). Adequate nutrition and a conducive intrauterine environment are essential for healthy fetal development. Nutrient deficiencies resulting from inadequate maternal nutrient ingestion may be compounded by alcohol-induced altered nutrient metabolism, placental clearance, and malabsorption. Alcohol-induced alteration of the intrauterine environment is the main source of developmental deficits and nutritional insufficiencies can worsen the effects on fetal development. In this review, we discuss studies examining the collective and interactive effects of nutrition (specifically iron, selenium, vitamin A, thiamine, zinc, folate, vitamin B12, choline, and amino acids) relative to gestational alcohol consumption and its effects on fetal growth and development. We also summarize scientific reports that tested potential benefits of micronutrient supplementation in animal models of fetal alcohol spectrum disorders and in humans. In summary, the deleterious effects of alcohol exposure in relation to nutrient homeostasis further validate that avoidance of alcohol consumption during pregnancy is the most effective way to mitigate the teratogenic effects of alcohol.

Micronutrient malnutrition is a key driver of morbidity and mortality for millions of children in South Asia. Understanding the specific micronutrients lacking in the diet during the complementary feeding period is essential for addressing undernutrition caused by inadequate diets. A Comprehensive Nutrient Gap Assessment was used to synthesize diverse evidence and estimate the public health significance of complementary-feeding micronutrient gaps and identify evidence gaps in 8 countries in South Asia. There were important gaps across the region in iron, zinc, vitamin A, folate, vitamin B12, and, to a lesser extent, calcium and vitamin C. The most nutrient-dense, whole-food sources of these micronutrients include liver, small fish, eggs, ruminant meat, and dark leafy greens. Investment is needed in some countries to collect data on micronutrient biomarkers and dietary intakes. A food systems approach is essential for improving child diets and reducing malnutrition, which affects millions of children, their futures, and society at large across South Asia and beyond.

Context In recent decades, obesity and type 2 diabetes mellitus (T2DM) have both become global epidemics associated with substantial healthcare needs and costs. Objective The aim of this review was to critically assess nutritional interventions for their impact on healthcare costs to community-dwelling individuals regarding T2DM or obesity or both, specifically using CHEERS (Consolidated Health Economic Evaluation Reporting Standards) criteria to assess the economic components of the evidence. Data Sources Searches were executed in Embase, EconLit, AgEcon, PubMed, and Web of Science databases. Study Selection Studies were included if they had a nutritional perspective, reported an economic evaluation that included healthcare costs, and focused on obesity or T2DM or both. Studies were excluded if they examined clinical nutritional preparations, dietary supplements, industrially modified dietary components, micronutrient deficiencies, or undernutrition; if they did not report the isolated impact of nutrition in complex or lifestyle interventions; or if they were conducted in animals or attempted to transfer findings from animals to humans. Data Extraction A systematic review was performed according to PRISMA guidelines. Using predefined search terms, 21 studies evaluating food habit interventions or taxation of unhealthy foods and beverages were extracted and evaluated using CHEERS criteria. Results Overall, these studies showed that nutrition interventions and taxation approaches could lead to cost savings and improved health outcomes when compared with current practice. All of the included studies used external sources and economic modeling or risk estimations with population-attributable risks to calculate economic outcomes. Conclusions Most evidence supported taxation approaches. The effect of nutritional interventions has not been adequately assessed. Controlled studies to directly measure economic impacts are warranted. [ABSTRACT FROM AUTHOR]

Studies on the efficacy of zinc supplementation for treatment or prevention of diarrhea have shown an inconsistent effect in populations at risk for zinc deficiency. Unlike drugs, which have no preexisting presence in the body, endogenous zinc must be assessed pharmacokinetically by isotope tracer studies. Although such methods have produced much data, very few studies have estimated the dose and the timing of dosing of zinc supplementation. This review examines drug kinetics used to establish the best dose, the timing of such doses, and the mechanism of action through pharmacodynamic markers and applies them, where possible, to zinc supplements. The findings reveal that little is known, especially in children at highest risk of zinc deficiency. Key data missing to inform proper dosing, whether for treatment of disease or for preventive nutrient supplementation, are noted. Addressing these uncertainties could improve study design, leading to future studies of zinc supplements that might be of greater benefit. [ABSTRACT FROM AUTHOR]

B vitamin deficiency is a leading cause of neurological impairment and disability throughout the world. Multiple B vitamin deficiencies often coexist, and thus an understanding of the complex relationships between the different biochemical pathways regulated in the brain by these vitamins may facilitate prompter diagnosis and improved treatment. Particular populations at risk for multiple B vitamin deficiencies include the elderly, people with alcoholism, patients with heart failure, patients with recent obesity surgery, and vegetarians/vegans. Recently, new clinical settings that predispose individuals to B vitamin deficiency have been highlighted. Moreover, other data indicate a possible pathogenetic role of subclinical chronic B vitamin deficiency in neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. In light of these findings, this review examines the clinical manifestations of B vitamin deficiency and the effect of B vitamin deficiency on the adult nervous system. The interrelationships of multiple B vitamin deficiencies are emphasized, along with the clinical phenotypes related to B vitamin deficiencies. Recent advances in the clinical determinants and diagnostic clues of B vitamin deficiency, as well as the suggested therapies for B vitamin disorders, are described. [ABSTRACT FROM AUTHOR]

Epidemiological studies suggest that certain micronutrients may improve or maintain cognitive function. Consistent demonstration of benefits in intervention trials has been elusive, possibly because most intervention trials do not select subjects on the basis of nutrient status and/or intake. The objective of this review was to identify levels of intake or markers of nutrient insufficiency that define at-risk older adult populations to determine whether these populations will benefit from nutritional intervention. This review examines evidence from interventional and prospective observational studies that evaluated the effects of folate, vitamin B12, and vitamin E on cognitive decline in older populations. The studies suggest that supplementation may protect against cognitive decline when serum folate is <12 nmol/L or vitamin E intake is <6.1 mg/day. The literature is inadequate to define a level for vitamin B12. Epidemiological studies investigating the relations of nutrients to cognitive decline should consider nutrient status in the reporting and interpretation of results. Randomized trials should design inclusion and exclusion criteria to select individuals with low intake and to disallow multivitamin intake. These recommendations may be useful for the design of valid trials and to advance the current understanding of nutrition and neurological diseases. [ABSTRACT FROM AUTHOR]

Coenzyme Q10 ( CoQ10) is the only lipid-soluble antioxidant that animal cells synthesize de novo. It is found in cell membranes and is particularly well known for its role in the electron transport chain in mitochondrial membranes during aerobic cellular respiration. A deficiency in either its bioavailability or its biosynthesis can lead to one of several disease states. Primary deficiency has been well described and results from mutations in genes involved in CoQ10 biosynthesis. Secondary deficiency may be linked to hydroxymethylglutaryl coenzyme A ( HMG- CoA) reductase inhibitors (statins), which are used for the treatment of hypercholesterolemia. Dietary contributions of CoQ10 are very small, but supplementation is effective in increasing plasma CoQ10 levels. It has been clearly demonstrated that treatment with CoQ10 is effective in numerous disorders and deficiency states and that supplementation has a favorable outcome. However, CoQ10 is not routinely prescribed in clinical practice. This review explores primary as well as statin-induced secondary deficiency and provides an overview of the benefits of CoQ10 supplementation. [ABSTRACT FROM AUTHOR]

It has been nearly 15 years since the first review on pregnancy and iron deficiency was published in Nutrition Reviews. Many unresolved issues raised in that seminal review have been addressed. New proteins involved in nonheme and heme iron transport have been identified in the enterocyte, and information on the roles of these proteins in the placenta is evolving. The systemic iron regulatory hormone, hepcidin, has since been identified as a key regulator of iron homeostasis. Additional data on the efficacy and consequences of prenatal iron supplementation are available. Emerging data on developmental changes in iron absorption across early infancy have further emphasized the need to ensure that the iron endowment of the neonate at birth is optimal. This is especially important, given growing evidence linking neonatal iron status with subsequent cognitive and neurobehavioral outcomes. Along with the many advances, new questions and gaps in knowledge have been identified. This review summarizes new data on maternal iron utilization across pregnancy as it impacts the pregnant woman and the iron status of the neonate at birth. [ABSTRACT FROM AUTHOR]

Deficiencies of nutrients such as amino acids, vitamins, lipids, and trace elements during gestation and early infanthood have strong deleterious effects on the development of the limbic system; these effects may be irreversible, even when adequate supplementation is provided at later developmental stages. Recent advances in the neurochemistry of biometals are increasingly establishing the roles of the trace elements iron, copper, zinc, and selenium in a variety of cell functions and are providing insight into the repercussions of deficiencies and excesses of these elements on the development of the central nervous system, especially the limbic system. The limbic system comprises diverse areas with high metabolic demands and differential storage of iron, copper, zinc, and selenium. This review summarizes available evidence suggesting the involvement of these trace elements in pathological disorders of the limbic system. [ABSTRACT FROM AUTHOR]

Traumatic brain injury is associated with a wide variety of behavioral deficits, including memory loss, depression, and anxiety. While treatments for these outcomes are currently limited, human clinical data suggest that supplemental zinc can be used during recovery to improve cognitive and behavioral deficits associated with brain injury. Additionally, pre-clinical models suggest that zinc may increase resilience to traumatic brain injury, making it potentially useful in populations at risk for injury. [ABSTRACT FROM AUTHOR]

In comparison with calcium, magnesium is an 'orphan nutrient' that has been studied considerably less heavily. Low magnesium intakes and blood levels have been associated with type 2 diabetes, metabolic syndrome, elevated C-reactive protein, hypertension, atherosclerotic vascular disease, sudden cardiac death, osteoporosis, migraine headache, asthma, and colon cancer. Almost half (48%) of the US population consumed less than the required amount of magnesium from food in 2005-2006, and the figure was down from 56% in 2001-2002. Surveys conducted over 30 years indicate rising calcium-to-magnesium food-intake ratios among adults and the elderly in the United States, excluding intake from supplements, which favor calcium over magnesium. The prevalence and incidence of type 2 diabetes in the United States increased sharply between 1994 and 2001 as the ratio of calcium-to-magnesium intake from food rose from <3.0 to >3.0. Dietary Reference Intakes determined by balance studies may be misleading if subjects have chronic latent magnesium deficiency but are assumed to be healthy. Cellular magnesium deficit, perhaps involving TRPM6/7 channels, elicits calcium-activated inflammatory cascades independent of injury or pathogens. Refining the magnesium requirements and understanding how low magnesium status and rising calcium-to-magnesium ratios influence the incidence of type 2 diabetes, metabolic syndrome, osteoporosis, and other inflammation-related disorders are research priorities.

National-level data on iron deficiency is not available for most countries and many rely on the prevalence of anemia as a proxy estimate, assuming that approximately 50% of anemia cases are caused by iron deficiency. Anemia, however, has multiple causal factors and the risk attributable to any one cause will depend on its relative importance in a population in relation to other causes. The present review summarizes current estimates on the prevalence of iron deficiency and anemia in children younger than 2 years and evaluates the strengths and weaknesses of currently available indicators of iron deficiency in children. Anemia prevalence is insufficient to estimate the prevalence of iron deficiency in children younger than 2 years. The methods widely used to assess iron deficiency at the population level rely on venous blood samples and are complicated and costly to implement. [ABSTRACT FROM AUTHOR]

Early iron deficiency not only affects brain and behavioral function during the period of iron deficiency, it persists long after treatment. The mechanisms include long-term alterations in dopamine metabolism, myelination, and hippocampal structure and function. Recent studies have demonstrated long-term genomic changes, which suggests the regulation of brain function is fundamentally altered. [ABSTRACT FROM AUTHOR]

Anemia and iron deficiency affect billions of people worldwide, especially women of reproductive age, pregnant women, and young children. Many countries have iron and folic acid supplementation programs for pregnant women. However, the impact of these programs is uncertain. Multiple-micronutrient supplementation during pregnancy has been advocated; however, it is unclear whether this has additional advantages. Overall, programs have shown only modest impact on increasing birth weight. This review discusses the present state of knowledge on interventions to improve iron status during pregnancy and reproductive health, and investigates other possibilities such as supplementation prior to conception to improve maternal and child health.

Consumption of cow's milk (CM) by infants and toddlers has adverse effects on their iron stores, a finding that has been well documented in many localities. Several mechanisms have been identified that may contribute to iron deficiency in this young population group. The most important of these is probably the low iron content of CM, which makes it difficult for infants to obtain the amounts of iron needed for growth. A second mechanism is the occult intestinal blood loss associated with CM consumption during infancy, a condition that affects about 40% of otherwise healthy infants. Loss of iron in the form of blood diminishes with age and ceases after the age of 1 year. A third mechanism is the inhibition of non-heme iron absorption by calcium and casein, both of which are present in high amounts in CM. Fortification of CM with iron, as practiced in some countries, can protect infants and toddlers against CM's negative effects on iron status. Consumption of CM produces a high renal solute load, which leads to a higher urine solute concentration than consumption of breast milk or formula, thereby narrowing the margin of safety during dehydrating events, such as diarrhea. The high protein intake from CM may also place infants at increased risk of obesity in later childhood. It is thus recommended that unmodified, unfortified CM not be fed to infants and that it be fed to toddlers in modest amounts only. [ABSTRACT FROM AUTHOR]

Anemia prevalence is highest in preschool children, women of reproductive age, and women who are pregnant. While the etiology of anemia is multifactorial, iron deficiency is the most commonly recognized nutritional cause. Observational studies imply that supplementation with iron or iron-folic acid should be started early in pregnancy, if not before, in order to prevent low-birth-weight and preterm delivery. Despite this, findings from clinical trials, even those conducted during early pregnancy, are equivocal. Recent follow-up studies of children born to women supplemented with iron-folic acid suggest that mortality is decreased and that the infant's iron endowment reflects the mother's iron status during pregnancy.

This article examines the association of iron deficiency (ID) and iron deficiency anemia (IDA) with children's development and behavior, with the goal of providing recommendations to prevent the developmental loss associated with these conditions. Children's risk for ID and IDA is particularly high during the second 6 months of life when prenatal stores are depleted. Longitudinal studies from infancy through adolescence and early adulthood suggest that socioemotional development is uniquely vulnerable to ID and IDA, perhaps being associated with shared neural pathways, and the effects of early iron deficiencies may be irreversible. In addition to direct effects on brain function, ID and IDA may also affect child development indirectly through non-responsive mother-child interactions. Maternal ID is a global problem that may contribute to high rates of maternal depression and non-responsive caregiving. Intervention trials illustrate that children benefit from both nutritional intervention and early learning interventions that promote responsive mother-child interactions. Recommendations to reduce the developmental loss associated with ID and IDA are to reduce the incidence of these conditions by efforts to prevent premature birth, delay cord clamping, ensure adequate maternal iron status, provide iron-rich complementary foods, and ensure access to postnatal interventions that promote responsive mother-infant interaction patterns and early learning opportunities for infants.

Reported here are three studies performed with the objective of finding ways to improve the iron status of breastfed infants and to prevent iron deficiency (ID). Participating infants were exclusively breastfed until 4 months of age; thereafter, they could receive complementary foods and, in some studies, supplemental formula. In the first study, infants were given medicinal iron between the ages of 1 and 5.5 months. During this period, iron status improved and ID was prevented; however, these benefits did not continue after the intervention ceased. In the second study, infants received medicinal iron or an equivalent amount of iron from an iron-fortified cereal between the ages of 4 and 9 months. Again, iron supplementation largely prevented ID from occurring, while non-anemic ID and ID anemia occurred in the control group as well as in the intervention groups before the intervention began. In the third study, infants received dry cereals fortified with electrolytic iron or with ferrous fumarate between the ages of 4 and 9 months. The cereals were equally effective in providing relative protection from ID. The results of these three studies indicate it is possible to protect breastfed infants from ID and IDA.

Several studies have documented the impact of vitamin D and other micronutrients on host responses to upper and lower respiratory tract infections, such as influenza and tuberculosis. These studies include observational as well as micronutrient intervention studies. Other studies have been conducted to understand the mechanisms by which micronutrients alter immune responses. However, critical information gaps and challenges remain. An immediate need exists for randomized controlled trials of vitamin D supplementation in high-risk populations, such as infants, children, and patients with immunocompromised health. Other important areas of research include vitamin D genetics, the impact of other micronutrient deficiencies on innate and adaptive immunity, the 25(OH)D threshold for insufficiency, the need for valuable reliable markers, standardization of assays to detect 25(OH)D, novel functional markers beyond serum 25(OH)D, and further development of in vitro and animal models that could be useful for preclinical studies. Lastly, a new systems biology approach is needed to address the complexity of micronutrient effects and regulation. [ABSTRACT FROM AUTHOR]

A literature review was conducted to investigate the status of vitamins and minerals in children with cerebral palsy and the implications of various deficiencies on health outcomes. Children with cerebral palsy commonly have feeding difficulties, which significantly impact their growth, general health, and life expectancy. Current nutritional literature focuses on energy expenditure, with little information available on other parameters, such as micronutrient status. Due to the paucity of micronutrient research in these children, the impacts of deficiencies and benefits in other populations have been considered. The role of micronutrients in maintaining cellular homeostasis throughout all body systems highlights a need for future research and monitoring of their levels, particularly in vulnerable populations with well-documented incidence of undernutrition.

Nutritional rickets has long been considered a disease caused by vitamin D deficiency, but recent data indicate that inadequate dietary calcium intake is an important cause of rickets, particularly in tropical countries. Children with rickets due to calcium deficiency do not have very low 25(OH)D concentrations, and serum 1,25(OH)D values are markedly elevated. Studies of Nigerian children with rickets demonstrated they have high fractional calcium absorption. A high-phytate diet was demonstrated to increase calcium absorption compared with the fasting state, and enzymatic dephytinization did not significantly improve calcium absorption. When given vitamin D, children with rickets have a marked increase in 1,25(OH)D concentrations without any change in fractional calcium absorption. No positive relationship was found between fractional calcium absorption and serum 25(OH)D concentrations in children on low-calcium diets. More research is needed to understand the interaction between calcium and vitamin D and the role of vitamin D in calcium absorption. [ABSTRACT FROM AUTHOR]

Although micronutrient deficiency is a global problem, the burden is not evenly shared within affected households. This review suggests that there are important non-linearities in relationships among food intake, sharing, and caring behavior within the household. Since micronutrient status relates to interactions among biological, social, behavioral, economic, and environmental processes, outcomes are not always predictable by age, gender, or location. Understanding such variability is crucial to identifying appropriate solutions. This review represents an exploratory first step toward unmasking population-specific variations that are important for better understanding the nature of micronutrient deficiencies and for improving the focus of public health action.

The article focuses on zinc treatment showing an antidepressant effect and its role in mood disorders. Psychiatric illnesses like depression and anxiety are seen as a critical problem for the 21st century by the World Health Organization. Nutrient deficiencies especially zinc deficiency may play an important role in the development of depression and mood disorders. Earlier studies showed that patients with major depression had low serum zinc levels. This could not be confirmed in later studies because of the complicated fact that many of the subjects in the study were resistant to treatment. Other reports show that treatment increases zinc concentrations to other regions of the brain. It may also be possible that zinc deficiency is secondary to the development of depression-related reductions in food intake. No relationship between serum zinc and food intake, anorexia, or body weight in depressed patients was found in many studies. The work on the function of zinc in the brain has focused on the role of zinc in neuronal transmitter and receptor activity.

Vitamin D deficiency is a problem of considerable magnitude that has reemerged as a major public health issue in the United States and several other developed countries. Vitamin D plays a crucial role in calcium homeostasis in the body. Hypovitaminosis D leads to osteomalacia and increased risk of fractures, especially in the elderly. Preliminary research suggests that vitamin D can prevent certain types of cancer and autoimmune diseases. A recent large study has shown the association between severe hypovitaminosis D and persistent, non-specific musculoskeletal pain, further suggesting that patients with no apparent cause of pain should be assessed and possibly treated for vitamin D deficiency.

Under experimental conditions, an acute nutrient deficiency (e.g., thiamin or folic acid) can be induced in both animal and human subjects. The signs and pathologic changes of an acute deficiency, however, may differ substantially from those seen clinically; often marginal deficiencies have been maintained over a long period of time.

Micronutrient deficiency is a serious public health concern in most developing countries. In India, iron deficiency, vitamin A deficiency, and iodine deficiency disorder are of greatest public health significance. In addition, subclinical zinc deficiency, flourosis, and fluoride-deficient dental caries are important areas of concern. The National Pilot Program on Control of Micronutrient Malnutrition was launched in 1995 to address these problems and the Department of Biochemistry and Nutrition of the All India Institute of Hygiene and Public Health (Calcutta) was entrusted to coordinate its activities. The program presently covers one northeastern and four eastern states, namely Assam, Bihar (Jharkhand), Orissa, West Bengal, and Tripura. Baseline analyses were conducted on demographic situation, food and nutrient intake pattern, nutritional deficiency diseases (e.g., iron deficiency anemia), iodine deficiency disorder, and vitamin A deficiency. It was observed that except for cereals, the diet was deficient in all other food groups. Nutrient intake (i.e., energy, protein, vitamins, and minerals) was also deficient in almost the entire state. Anthropometric indices (e.g., weight-forage and height-for-age data) indicated that large percentages of 5-year-old and 6-14-year-old children were in grade II or III malnutrition. Mean dietary zinc intakes in all the surveyed districts were much lower than the RDA. Large percentages of salt samples had iodine levels less than 15 ppm. The point prevalence of anemia in various age groups was found to be high. Bitot's spot was mainly noted in the age group of 6 -71 months. Nightblindness was noted in young children as well as the children 24-71 months old. High prevalence of nightblindness in pregnant women is a point of concern. Actions needed to control micronutrient deficiencies include: intervention strategies, extensive nutrition and health education through innovative IEC materials to support problem-specific programs, strengthening of various state government programs and the role of NGOs.
