[PMID: 37686773 PMCID: PMC10489979 DOI: 10.3390/nu15173742] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 08/23/2023] [Accepted: 08/24/2023] [Indexed: 09/10/2023] Open
Abstract
Vitamin D deficiency is a global public health concern with significant implications for bone health and chronic disease prevention. Our aim was to summarize the evidence from Cochrane and other systematic reviews evaluating the benefits or harms of vitamin D fortification of staple foods for household use. In April 2023, we systematically searched Ovid MEDLINE, Embase, Epistemonikos and the Cochrane Database of Systematic Reviews for systematic reviews investigating the effects of vitamin D fortification of food in general populations of any age. We used Cochrane methodology and assessed the methodological quality of included studies using AMSTAR (A MeaSurement Tool to Assess Systematic Reviews). We assessed the degree of overlap among reviews. All outcomes included in systematic reviews were assessed. The protocol is registered in PROSPERO (registration number: CRD42023420991). We included 27 systematic reviews out of 5028 records for analysis. Overall, 11 out of 12 systematic reviews calculating pooled estimates reported a significant increase in serum 25(OH)D concentrations. The mean change in serum 25(OH)D concentrations per additional 100 units of vitamin D ranged from 0.7 to 10.8 nmol/L. Fortification of food with vitamin D showed a reduction in the prevalence of vitamin D deficiency based on high-certainty evidence. Parathormone (PTH) levels were described to decrease, bone mineral density to increase, while the effects on other bone turnover markers were inconsistent. Fortification did not significantly impact most anthropometric parameters, but it seemed to positively influence lipid profiles. In summary, fortification of food with vitamin D results in a reduction of vitamin D deficiency and might increase serum 25(OH)D concentrations, to varying extents depending on the fortified vehicle and population characteristics. Additionally, fortification may have a positive impact on bone turnover and lipid metabolism but may only have a limited effect on anthropometric parameters.

Abstract
We aimed to determine the efficacy of multiple micronutrient supplementation on the biomarkers of iron, zinc, and vitamin A status across anthropometric status categories in Vietnamese school children. In this 22-week randomised controlled trial, 347 undernourished, normal weight, or overweight/obese children aged 6-9 years were allocated to receive every school day a multiple micronutrient supplement (10 mg iron, 10 mg zinc, 400 µg vitamin A) or a placebo. Haematological indices; circulating ferritin, zinc, and retinol (corrected for inflammation); and C-reactive protein were measured at baseline and 22 weeks. At week 22, linear mixed models showed that mean corpuscular volume increased by 0.3 fL, serum ferritin by 9.1 µg/L, plasma zinc by 0.9 µmol/L, and plasma retinol by 15%, and the prevalence of zinc deficiency decreased by 17.3% points in the intervention group compared to placebo. No intervention effects were found for other haematological indices, or the prevalence of anaemia. Multiple micronutrient supplementation for 22 weeks improved the biomarkers of zinc and vitamin A status and some biomarkers of iron status, and reduced the prevalence of zinc deficiency in Vietnamese school children.Trial registration: This trial was registered on 06/09/2016 at www.anzctr.org.au as ACTRN12616001245482.

High dietary micronutrient inadequacy in peri-urban school children from a district in South India: Potential for staple food fortification and nutrient supplementation. MATERNAL & CHILD NUTRITION 2020; 16 Suppl 3:e13065. [PMID: 33347729 PMCID: PMC7752122 DOI: 10.1111/mcn.13065] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Revised: 06/23/2020] [Accepted: 07/01/2020] [Indexed: 12/04/2022]
Abstract
Multiple micronutrient deficiencies (MNDs) co-exist, often because of poor intakes and adversely impact health. Habitual diets were assessed in 300 school children (6-17 years old) recruited from two government schools by simple random sampling. Probability of adequacy (PA) for 11 micronutrients and mean probability of adequacy (MPA) was calculated. Haemoglobin, plasma ferritin, folic acid, vitamin B12 and C-reactive protein were estimated. Descriptive statistics and regression analysis were used to estimate magnitude and factors associated with MNDs. The contribution of fortified foods and/or supplements in addressing inadequacies and excessive intakes was modelled. The PA ranged from 0.04 for folate to 0.70 for zinc, and the MPA was 0.27. Prevalence of anaemia (53%), iron deficiency (57%; ID), iron deficiency anaemia (38%; IDA), folate deficiency (24%) and B12 deficiency (43%) was high. Dietary inadequacy of iron, zinc and a low MPA was associated with anaemia and IDA. Inclusion of double fortified salt (DFS), fortified rice (FR) or iron folic acid (IFA) supplements individually in habitual diet reduced probability of iron inadequacy significantly from 82% to ≤13%. Inclusion of DFS and FR simultaneously led to disappearance of iron inadequacy, but risk of excessive intake increased to 16%. Inclusion of DFS, FR and IFA together increased risk of excess iron intake to 40%. Nevertheless, intakes of folate and B12 remained inadequate even with FR and/or IFA. These results indicate a high risk of dietary MNDs in children and suggest need for more systematic intake measurements in representative sample and adjustment of iron dosages to avoid excessive intakes.

Retention, stability, iron bioavailability and sensory evaluation of extruded rice fortified with iron, folic acid and vitamin B 12. MATERNAL & CHILD NUTRITION 2020; 16 Suppl 3:e12932.

Abstract
Fortification of rice with micronutrients using extrusion technology is considered a sustainable strategy to prevent nutritional deficiencies in general population. The objective of the present study is to assess the retention, stability and iron bioavailability from indigenously developed triple fortified rice (iron, folic acid and vitamin B12 ) during rinsing and different cooking methods. Further, we also assessed the acceptability of fortified rice in adult human volunteers. The retention of iron during rinsing with excess water was ≥90%, whereas folic acid and vitamin B12 levels were reduced by ~25% during rinsing. Watertight cooking of rice (in electric cooker or on flame) had no additional effect on the nutrient levels as compared with rinsed rice, implying their stability during cooking. However, cooking with excess water followed by decanting led to loss of 45% iron and ≥70% folic acid and vitamin B12 . The dialyzable iron and ferritin synthesis in Caco-2 cells was significantly (P < .01) higher from fortified rice compared with unfortified rice. In addition, inclusion of ascorbic acid significantly (P < .01) increased the iron bioavailability from the fortified rice. Triangle tests in adult human subjects revealed that there are no significant sensory differences among fortified and unfortified rice. Further, fortified rice consumption appears to bridge the gaps in dietary iron intake deficits in children and women of reproductive age. These results suggest that the iron-, folic acid- and vitamin B12 -fortified rice has higher retention and stability of fortified nutrients and is acceptable for consumption in adult human volunteers.

Abstract
Vitamin C is an essential nutrient that must be obtained through the diet in adequate amounts to prevent hypovitaminosis C, deficiency and its consequences-including the potentially fatal deficiency disease scurvy. Global vitamin C status and prevalence of deficiency has not previously been reported, despite vitamin C's pleiotropic roles in both non-communicable and communicable disease. This review highlights the global literature on vitamin C status and the prevalence of hypovitaminosis C and deficiency. Related dietary intake is reported if assessed in the studies. Overall, the review illustrates the shortage of high quality epidemiological studies of vitamin C status in many countries, particularly low- and middle-income countries. The available evidence indicates that vitamin C hypovitaminosis and deficiency is common in low- and middle-income countries and not uncommon in high income settings. Further epidemiological studies are required to confirm these findings, to fully assess the extent of global vitamin C insufficiency, and to understand associations with a range of disease processes. Our findings suggest a need for interventions to prevent deficiency in a range of at risk groups and regions of the world.

Abstract
OBJECTIVE Vitamin D (vitD) deficiency is a global childhood health problem. Food fortification is a promising strategy to curb vitD deficiency. We aimed to assess the effectiveness of utilizing vitD fortification in staple foods to improve 25hydroxyvitamin D (25(OH)D) concentration and to reduce the prevalence of vitD deficiency among healthy children. METHODS We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating the use of vitD fortified food products compared to no fortification among healthy children aged 1-18 years old. We searched Medline, Embase, Global Health, and Cochrane (CENTRAL) databases from database inception until May 2019. Independently, six reviewers in pairs screened titles and abstracts, assessed the full text for eligibility, and performed data extraction and quality assessment. The primary outcome is the impact of fortification on 25(OH)D concentration. The secondary outcomes included the impact of fortification on the prevalence of vitD deficiency, school performance, cognitive function, school absences, infection rate, hospital admission length, and compliance with fortified food product consumption. RESULTS We identified 2229 articles. After assessing eligibility, 20 RCTs met the inclusion criteria. The eligible RCTs assessed the fortification of milk, cereal, juice, bread, yogurt, and cheese compared with no fortification. All RCTs, except for three, had a low risk of bias. Food fortification improved 25(OH)D concentration by a mean difference (MD) of 15.51 nmol/L (95% confidence interval (CI) 6.28, 24.74; I2 = 99%), which resulted in a mean increase of 3 nmol/l for every 100 IU of vitD, when adjusted for baseline 25(OH)D concentration and country latitude. Additionally, the prevalence of vitD deficiency decreased by a risk ratio of 0.53 (95% CI 0.41, 0.69; I2 = 95%), and cognitive function improved by a MD of 1.22 intelligence quotient (IQ) points (95% CI 0.65, 1.79; I2 = 0%). The overall evidence quality was high. CONCLUSION VitD food fortification is an effective way to improve 25(OH)D concentration, prevent vitD deficiency, and improve IQ levels.

MATERNAL & CHILD NUTRITION 2020; 16:e12915. [PMID: 31773841 PMCID: PMC7083483 DOI: 10.1111/mcn.12915] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 10/30/2019] [Accepted: 10/31/2019] [Indexed: 11/29/2022]
Abstract
In Peru, nearly half of children aged 6-36 months were diagnosed with anaemia in 2017. To address this disease, the Peruvian Ministry of Health implemented a national programme in 2014, distributing free micronutrient powders (MNPs) to all children of this age. However, rates of childhood anaemia remain high. The aim of this study was to explore factors at all levels of the Social-Ecological Model that affect MNP use and adherence in Arequipa, an Andean city with childhood anaemia rates higher than the national average. We conducted in-depth interviews with 20 health personnel and 24 caregivers and 12 focus group discussions with 105 caregivers. We identified numerous barriers, including negative side effects (constipation, vomiting, and diarrhoea), poor taste of MNP, lack of familial and peer support for its use, insufficient informational resources provided by the health system, and limited human resources that constricted health personnel abilities to implement MNP programming successfully. Facilitators identified included concern about the long-term effects of anaemia, support from organizations external to the health system, well-coordinated care within the health system, and provision of resources by the Ministry of Health. We found that community or organizational and societal factors were key to limited MNP use and adherence, specifically the limited time health personnel have to address caregivers' doubts during appointments and the lack of informational resources outside of these appointments. Potential policy implications could be to increase informational resources available outside of individualized counselling by strengthening existing collaborations with community organizations, increasing media coverage, and providing group counselling.

Abstract
The latest National Family Health Survey conducted in 2015-16 (NFHS-4) showed that malnutrition and anaemia still pose huge health challenges in India. Data on 651,642 adult non-pregnant women aged 15-49 years were taken from the survey to study the nutritional and anaemia statuses of adult women by Indian zone and state. The relationships of these two variables with the women's urban/rural place of residence, education level, religion and eating habits, and wealth index of the family, were assessed. Body Mass Index (BMI) and haemoglobin level were used to assess nutritional status and level of anaemia, respectively. The results show that in 2015-16 in India the percentages of underweight and obese/overweight people were 22.4% and 18.4%, respectively. The percentages of undernutrition and overnutrition were more or less same. The percentage of underweight people was higher in the middle belt region of India. Zones with high levels of overweight or obesity were concentrated in the West, North and South zones. A comparison of the two national-level data sets, i.e. NFHS-4 and NFHS-3, showed that the prevalences of undernutrition and anaemia reduced by 13 and 5 percentage points, respectively, from NFHS-3 to NFHS 4, i.e. over the 10-year period from 2004-05 to 2015-16, whereas overnutrition increased by 4 percentage points during this period. Analysis of possible socio-demographic factors and eating habits thought to influence underweight, obesity and anaemia revealed substantive causal relations. More specifically, education and eating habit were found to influence underweight, overweight or obesity and anaemia significantly. The nutritional status of a woman was also found to depend on household income.

Abstract
Plasma homocysteine level and megaloblastic anemia status are two factors that can affect the quality of life of patients with multiple sclerosis (MS). We conducted this study to determine the effect of vitamin B12 and folic acid supplementation on serum homocysteine, megaloblastic anemia status and quality of life of patients with MS. A total of 50 patients with relapsing remitting multiple sclerosis (RRMS) included in this study which divided into 2 groups. The vitamin group received 5 mg folic acid tablet daily and 3 doses of vitamin B12 (1,000 mcg) injection and the other group received placebo and normal saline injection (same doses). The quality of life was measured by using Multiple Sclerosis Quality of Life-54 questionnaire (MSQOL-54). Fully automated fluorescence polarization immunoassay was used to measure serum homocysteine, vitamin B12 and folate. Complete blood count blood test was conducted to determine the anemia status. The mean homocysteine level reduced by 2.49 ± 0.39 µmol/L (p = 0.001), hemoglobin increased from 11.24 ± 1.54 to 13.12 ± 1.05 g/dL (p = 0.001), and mean corpuscular volume decreased from 95.50 ± 6.65 to 89.64 ± 4.24 in the vitamin group (p = 0.001). There was a significant improvement in the mental field of life quality in the placebo group (37.46 ± 19.01 to 50.98 ± 21.64; p = 0.001), whereas both physical and mental fields of quality of life were improved significantly in the vitamin group (40.38 ± 15.07 to 59.21 ± 12.32 and 29.58 ± 15.99 to 51.68 ± 18.22, respectively; p = 0.001). Serum homocysteine level decrease and anemia status improvement with vitamin B12 and folic acid supplementation reveal the potential role of these two vitamins in improving the life quality of MS patients.

Abstract
Folate has been studied in relation to many diseases, especially cancer. Although it has been postulated to exert a dual effect on development of cancer, its role remains to be clearly defined. Its effect on cancer is the result of gene-nutrient interaction between the genes in folate metabolic pathway and dietary folate availability; mutations in genes of folate metabolism have been shown to alter individual susceptibility to certain childhood cancers as well as response to cancer chemotherapy. Although mandatory fortification of food items with folate has been initiated in some countries, many countries are yet to adopt this due to concerns about undesired adverse effects of high folate levels on health, especially cancer. However, initial reports suggest that folate fortification has led to reduction in incidence of certain childhood cancers such as neuroblastoma, wilms tumour and leukaemias. Despite studies showing folate depletion during antifolate chemotherapy and higher toxicity of chemotherapy in folate-depleted individuals, folate supplementation during cancer chemotherapy is not routinely recommended. Studies investigating the precise effect of folate supplementation during chemotherapy on both short- and long-term outcomes of cancer are needed to arrive at a consensus guideline.

Abstract
Biofortification of maize with provitamin A (pro-VA) carotenoids has been successful, but the bioavailability of carotenoids needs to be explored. In the present study, we investigated the carotenoid content, micellarization and intestinal cell uptake of carotenoids from 10 maize hybrids [normal maize, quality protein maize (QPM), pro-VA carotenoid and double biofortified QPM + pro-VA maize hybrids] using a simulated in vitro digestion/Caco-2 cell model. The pro-VA carotenoid content of biofortified maize hybrids is 2-10 fold higher compared to that of normal maize. Furthermore, the ratio of non-pro-VA carotenoids lutein (LUT) plus zeaxanthin (ZEA) to the sum of pro-VA carotenoids β-cryptoxanthin (BCX), α-carotene (AC) and β-carotene (BC) in biofortified maize was much lower compared to that of normal maize. The consumption of 200 g day-1 of biofortified Pusa-PV-16-3 (BC = 808.4 μg per 100 g; AC = 839.3 μg per 100 g; BCX = 59 μg per 100 g) and Pusa-APQH8 (BC = 345.9 μg per 100 g; AC = 1739 μg per 100 g; BCX = 644.2 μg per 100 g) maize would contribute to 52 and 64% of RDAs for adult Indian men, respectively, after adjusting for cooking losses and conversion factors. The mean efficiency of micellarization of LUT (62.2% ± 5.3), ZEA (65% ± 4.7), and BCX (54% ± 9.5) exceeded that of AC (43% ± 8.9) and BC (49.8% ± 7.8) from all the maize hybrids. Furthermore, the micellarization and uptake in Caco-2 cells during a 4 h incubation period showed high correlation (P < 0.05) with the concentration of carotenoids in the maize digesta and micellar fraction, respectively. However, the LUT + ZEA content in the maize digesta and micellar fraction was inversely (p < 0.05) related to the BC micellarization and intestinal cell uptake, respectively. These results together suggest that the enrichment of pro-VA carotenoids together with decreasing the oxygenated carotenoid metabolites such as LUT and ZEA will further improve the bioavailability of BC from maize hybrids.

Prevalence of Vitamin B 12 and Folate Deficiency in School Children Residing at High Altitude Regions in India. Indian J Pediatr 2017; 84:289-293. [PMID: 28108882 DOI: 10.1007/s12098-017-2291-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2016] [Accepted: 01/02/2017] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To assess the prevalence of vitamin B12 and folate deficiencies among children residing at high altitude regions of Himachal Pradesh, India. METHODS A total of 215 school children in the age group of 6-18 y were included. Biochemical estimation of serum vitamin B12 and folate levels was undertaken using chemiluminescence immunoassay method. The consumption pattern of foods high in dietary vitamin B12 and folate was recorded using Food Frequency Questionnaire. RESULTS The median levels (interquartile range) of serum vitamin B12 and folate were 326 (259-395) pg/ml and 7.7 (6-10) ng/ml respectively. The prevalence of vitamin B12 and folate deficiency amongst school age children was found as 7.4% and 1.5% respectively. CONCLUSIONS A low prevalence of vitamin B12 and folate deficiencies was found amongst children aged 6-18 y living at high altitude regions in India. This is possibly due to high frequency of consumption of foods rich in vitamin B12 and folate.

Abstract
Dietary fat increases carotenoid bioavailability by facilitating their transfer to the aqueous micellar fraction during digestion. However, the specific effect of both quantity and type of dietary fat required for optimal carotenoid absorption remained unexplored. In the present study, the effect of amount and type of vegetable oils on carotenoid micellarization from carrot, spinach, drumstick leaves and papaya using in vitro digestion/Caco-2 cell model have been assessed. Although, dietary fat (0.5-10% w/w) significantly increased the micellarization of carotenoids from all the test foods, the extent of increase was determined by the food matrix (papaya > drumstick = spinach > carrot) and polarity of carotenoids (lutein > β-carotene = α-carotene > lycopene). Among the dietary fats tested the carotenoid micellarization was twofold to threefold higher with dietary fat rich in unsaturated fatty acids (olive oil = soybean oil = sunflower oil) compared to saturated fatty acids (peanut oil = palm oil > coconut oil). Intestinal cell uptake of lutein exceeded that of β-carotene from micellar fraction of spinach leaves digested with various oils. However, cellular uptake of β-carotene is depended on the carotenoid content in micellar fraction rather than the type of fat used. Together these results suggest that food matrix, polarity of carotenoids and type of dietary fat determines the extent of carotenoid micellarization from vegetables and fruits.

Abstract
Background Adequate folate intake and levels are advisable throughout life but are of particular importance during adolescence, a period of rapid growth. However, folate insufficiency in economically deprived Indian adolescents is understudied. Objective This cross-sectional study examined the prevalence of folate deficiency and adequacy of folate intake of 224 tribal Indian adolescents (10 to 17 years of age). The secondary aim was to study the association between anemia status and folate status. Methods Radioimmunoassay, multiple-pass 24-hour dietary recall, and HemoCue were used to measure red blood cell (RBC) folate, folate intake, and anemia status, respectively. Results The geometric mean (95% CI) RBC folate concentration (nmol/L) was 360.2 (329.7 to 393.6), and the mean ± SD folate intake (μg/day) and hemoglobin level (g/L) were 159.9 ± 44.7 and 125.4 ± 13.0, respectively. Almost half of boys and girls aged 10 to 12 and 13 to 15 years and 66.7% of girls aged 16 to 17 years were deficient in RBC folate (< 340 nmol/L). The mean ± SD folate intake (μg/day) of girls (139.4 ± 34.5) was lower than that of boys (173.8 ± 45.5) ( p < .001). With respect to adequacy of folate intake, a greater proportion of girls in the age group of 13–15 years (78.5% vs 38.6%, p < 0.001) and 16–17 years (100.0% vs 76.9%, p = 0.04) had intakes below their Recommended Dietary Allowance (RDA). No association was observed between folate intake and RBC folate deficiency or between anemia status and RBC folate deficiency. Conclusions Folate insufficiency was widespread in tribal Indian adolescents. There is an urgent need to develop culturally sensitive strategies for improvement.

Abstract
OBJECTIVE There is evidence that subclinical vitamin B12 (B12) deficiency is common in India. Vegetarianism is prevalent and therefore meat consumption is low. Our objective was to explore the contribution of B12-source foods and maternal B12 status during pregnancy to plasma B12 concentrations. DESIGN Maternal plasma B12 concentrations were measured during pregnancy. Children's dietary intakes and plasma B12 concentrations were measured at age 9.5 years; B12 and total energy intakes were calculated using food composition databases. We used linear regression to examine associations between maternal B12 status and children's intakes of B12 and B12-source foods, and children's plasma B12 concentrations. SETTING South Indian city of Mysore and surrounding rural areas. SUBJECTS Children from the Mysore Parthenon Birth Cohort (n 512, 47.1 % male). RESULTS Three per cent of children were B12 deficient (<150 pmol/l). A further 14 % had 'marginal' B12 concentrations (150-221 pmol/l). Children's total daily B12 intake and consumption frequencies of meat and fish, and micronutrient-enriched beverages were positively associated with plasma B12 concentrations (P=0.006, P=0.01 and P=0.04, respectively, adjusted for socio-economic indicators and maternal B12 status). Maternal pregnancy plasma B12 was associated with children's plasma B12 concentrations, independent of current B12 intakes (P<0.001). Milk and curd (yoghurt) intakes were unrelated to B12 status. CONCLUSIONS Meat and fish are important B12 sources in this population. Micronutrient-enriched beverages appear to be important sources in our cohort, but their high sugar content necessitates care in their recommendation. Improving maternal B12 status in pregnancy may improve Indian children's status.

Abstract
OBJECTIVE To combine evidence from randomized controlled trials to assess the effect of Fe-fortified foods on mean Hb concentration in children (<10 years). DESIGN We conducted a meta-analysis of randomized, controlled, Fe-fortified feeding trials that evaluated Hb concentration. The weighted mean difference was calculated for net changes in Hb by using random-effects models. Meta-regression and covariate analyses were performed to explore the influence of confounders on the net pooled effect. SETTING Trials were identified through a systematic search of PubMed, the Cochrane Library and secondary references. SUBJECTS Eighteen studies covering 5142 participants were identified. The duration of feeding of fortified foods ranged from 6 to 12 months in these studies. RESULTS Eighteen studies were included and evaluated in the meta-analysis. The overall pooled estimate of Hb concentration showed a significant increase in the fortification group compared with the control group (weighted mean difference = 5·09 g/l; 95% CI 3·23, 6·95 g/l; I 2 = 90%, τ 2 = 18·37, P < 0·0001). Meta-regression analysis indicated that duration of feeding was positively related to the effect size (regression coefficient = 0·368; 95% CI 0·005, 0·731; P < 0·05). The net pooled effect size after removing the confounders was 4·74 (95% CI 3·08, 6·40) g/l. CONCLUSIONS We observed an association between intake of Fe-fortified foods and Hb concentration in children aged <10 years. Fe-fortified foods could be an effective strategy for reducing Fe-deficiency anaemia in children.

Abstract
Several micronutrient deficiencies affect functional, particularly cognition and physical performance of children. Identifying and preventing sub-clinical deficiencies may be important so that adverse effects on functional performance by these deficiencies, particularly of iron and the B vitamins, are prevented. There is also the potential for childhood micronutrient deficiencies to have long-term effects that affect health and productivity in adulthood. This is especially relevant in a developing country such as India, which faces the dual burden of malnutrition and where the prevalence of these deficiencies is high. This review highlights the extent of micronutrient deficiencies in Indian children and focuses on the effect of deficiencies of the B vitamins and iron on cognitive and physical performance in children. Most studies on multiple micronutrient supplementation or fortification in Indian school children show modest effects on cognitive and physical performance, and it is relevant to point out that these studies have largely been conducted on urban children with mild deficiency at most; children with moderate or severe deficiency have not been studied. However, diets of rural children indicate large deficits in micronutrient intake, particularly of folic acid, riboflavin and iron, and their consequences have not been studied. With the limited evidence available, a short term but economical solution to ensure adequate micronutrient intakes could be through the fortification of staple cereals taken throughout the day. As increasing household incomes translate into an increase in food expenditure and diet diversification, it may become necessary to define upper limits of intake for nutrients in India, particularly as many commercial foods are fortified.

Abstract
Vitamin B(12) is an essential micronutrient synthesized by microorganisms. Mammals including humans have evolved ways for transport and absorption of this vitamin. Deficiency of vitamin B(12) (either due to low intake or polymorphism in genes involved in absorption and intracellular transport of this vitamin) has been associated with various complex diseases. Genome-wide association studies have recently identified several common single nucleotide polymorphisms (SNPs) in fucosyl transferase 2 gene (FUT2) to be associated with levels of vitamin B(12)-the strongest association was with a non-synonymous SNP rs602662 in this gene. In the present study, we attempted to replicate the association of this SNP (rs602662) in an Indian population since a significant proportion has been reported to have low levels of vitamin B(12) in this population. A total of 1146 individuals were genotyped for this SNP using a single base extension method and association with levels of vitamin B(12) was assessed in these individuals. Regression analysis was performed to analyze the association considering various confounding factors like for age, sex, diet, hypertension, diabetes mellitus and coronary artery disease status. We found that the SNP rs602662 was significantly associated with the levels of vitamin B(12) (p value<0.0001). We also found that individuals adhering to a vegetarian diet with GG (homozygous major genotype) have significantly lower levels of vitamin B(12) in these individuals. Thus, our study reveals that vegetarian diet along with polymorphism in the FUT2 gene may contribute significantly to the high prevalence of vitamin B(12) deficiency in India.

Abstract
Background To compare disability prevalence rates in the major ethnic groups in the UK and understand the risk factors contributing to differences identified. It was hypothesised that Indian Asian and African Caribbean people would experience higher rates of disability compared with Europeans. Methods Data was collected from 888 European, 636 Indian Asian and 265 African Caribbean men and women, aged 58–88 years at 20-year follow-up of community-based cohort study, based in West London. Disability was measured using a performance-based locomotor function test and self-reported questionnaires on functional limitation, and instrumental (IADL) and basic activities of daily living (ADL). Results The mean (SD) age of participants at follow-up was 69.6 (6.2) years. Compared with Europeans, Indian Asian people were significantly more likely to experience all of the disability outcomes than Europeans; this persisted after adjustment for socioeconomic, behavioural, adiposity and chronic disease risk factors measured at baseline (locomotor dysfunction: adjusted odds ratio (OR) 2.20, 95% CI 1.56–3.11; functional limitation: OR 2.77, 2.01–3.81; IADL impairment: OR 3.12, 2.20–4.41; ADL impairment: OR 1.58, 1.11–2.24). In contrast, a modest excess risk of disability was observed in African Caribbeans, which was abolished after adjustment (e.g. locomotor dysfunction: OR 1.37, 0.90–1.91); indeed a reduced risk of ADL impairment appeared after multivariable adjustment (OR from 0.99, 0.68–1.45 to 0.59, 0.38–0.93), compared with Europeans. Conclusions Substantially elevated risk of disability was observed among Indian Asian participants, unexplained by known factors. A greater understanding of determinants of disability and normative functional beliefs of healthy aging is required in this population to inform intervention efforts to prevent disability.

Abstract
AbstractObjectiveTo review evidence on the associations between vitamin B12intake and its biomarkers, vitamin B12intake and its functional health outcomes, and vitamin B12biomarkers and functional health outcomes.DesignA systematic review was conducted by searching electronic databases, until January 2012, using a standardized strategy developed in the EURRECA network. Relevant articles were screened and sorted based on title and abstract, then based on full text, and finally included if they met inclusion criteria. A total of sixteen articles were included in the review.SettingArticles covered four continents: America (n4), Europe (n8), Africa (n1) and Asia (n3).SubjectsPopulation groups included healthy infants, children and adolescents, and pregnant and lactating women.ResultsFrom the total number of 5815 papers retrieved from the initial search, only sixteen were eligible according to the inclusion criteria: five for infants, five for children and adolescents, and six for pregnant and lactating women.ConclusionsOnly one main conclusion could be extracted from this scarce number of references: a positive association between vitamin B12intake and serum vitamin B12in the infant group. Other associations were not reported in the eligible papers or the results were not provided in a consistent manner. The low number of papers that could be included in our systematic review is probably due to the attention that is currently given to research on vitamin B12in elderly people. Our observations in the current systematic review justify the idea of performing well-designed studies on vitamin B12in young populations.

Abstract
Fortifying rice with multiple micronutrients could be a promising strategy for combat micronutrient deficiencies in developing countries. We determined the efficacy of extruded rice grains fortified with multiple micronutrients on the prevalence of anemia, micronutrient status, and physical and cognitive performance in 6- to 12-y-old, low-income school children in Bangalore, India. In a randomized, double-blind, controlled trial, 258 children were assigned to 1 of 3 intervention groups to receive rice-based lunch meals fortified with multiple micronutrients with either low-iron (6.25 mg) or high-iron (12.5 mg) concentrations or identical meals with unfortified rice. The meals were provided 6 d/wk for 6 mo. Anthropometric, biochemical, physical performance, and cognitive assessments were taken at baseline and endpoint. At baseline, study groups were comparable, with 61% of the children being anemic. However, only <10% were deficient in iron, vitamin A, and zinc. After 6 mo, plasma vitamin B-12 and homocysteine concentrations (both P < 0.001) as well as physical performance (P < 0.05) significantly improved in the intervention arms. No between-group differences were observed in hemoglobin concentration, anemia, and deficiencies of other micronutrients or cognitive function after 6 mo, but paired analyses revealed a small reduction in anemia prevalence in children in the low-iron group. The fortified rice was efficacious in improving vitamin B-12 status and physical performance in Indian school children.

Abstract
BACKGROUND Zinc is important in adolescence because of its role in growth and sexual maturation. Adolescents from developing countries such as India may be at high risk of zinc deficiency because of unwholesome food habits and poor bioavailability of zinc from plant-based diets. OBJECTIVE (1) to study zinc status and its association with profile of other micronutrients, (2) to construct a simple tool in the form of Adolescent Micronutrient Quality Index (AMQI) to assess quality of diets of the girls and (3) to examine the effect of zinc supplement on health of adolescent girls. METHODS Girls (10-16 years) from two secondary schools of Pune, Maharashtra state, in Western India were enrolled in a cross-sectional study (n = 630). Data were collected on dietary intake, cognitive performance, taste acuity, haemoglobin, erythrocyte zinc and plasma levels of zinc, vitamin C, β-carotene and retinol. AMQI was developed using age-sex-specific Indian dietary guidelines and healthy foods and habits described in the recent US dietary guidelines. Zinc-rich recipes were developed considering habitual diets of the girls and vegetarian sources of zinc. An intervention trial (n = 180) was conducted to assess the effect of zinc-rich dietary supplements and ayurvedic zinc (Jasad) supplementation. RESULTS Prevalence of micronutrient deficiencies was high in these girls. Poor cognitive performance was seen in half of the girls, and salt taste perception was affected in 45%. AMQI was correlated with nutrient intakes and blood micronutrient levels (p < 0.01), indicating the potential of AMQI to measure micronutrient quality of diets of adolescent girls. Results of the intervention trial indicated that supplementation of zinc-rich recipes vis-a-vis ayurvedic Jasad zinc has the potential to improve plasma zinc status, cognitive performance and taste acuity in adolescent girls. CONCLUSIONS Review of the studies on Indian adolescent girls demonstrates the necessity of adopting zinc and micronutrient-rich diets for positive health building in adolescents.

Abstract
BACKGROUND Anemia is one of the major leading nutritional deficiencies in India, and the most vulnerable groups are preschool and adolescent children and pregnant and lactating women. AIM The main objective of the study is to determine the temporal trend of anemia among reproductive-aged women of age 15-49 years. METHODOLOGY The study uses data from second and third rounds of the National Family Health Surveys (NFHS-2, 1998-1999, and NFHS-3, 2005-2006), conducted by the International Institute for Population Sciences. The dependent variable was the status of anemia of women. The determining variables were type of residence, age group, religion and castes, educational status, marital status, and household standard of living index. RESULTS Anemia was most prevalent in the east zone for both the periods. The changes at the all India level were not much, but the north-east zone improved very well, whereas the south zone deteriorated drastically. The occurrence of severely anemic women in India varied between 1% and 2%. The highest prevalence rates were observed among women who were 15 to 24 years of age, illiterate, from non-Christian scheduled tribes (STs), unmarried, and whose standard of living was low. Rates of anemia have increased over time except in the case of Buddhists, Parsees, Jains, and the STs. CONCLUSION From the viewpoint of our study, illiteracy and low standard of living may be the main causes of anemia among women in India. It is also necessary to take appropriate steps to curb anemia in women in their early adulthood.

Abstract
OBJECTIVE To develop a psychometrically valid questionnaire for testing knowledge on micronutrients and to assess the relationship between knowledge and biomarkers of micronutrient status among adolescents. DESIGN Cross-sectional, institution-based, validity and reliability study. SETTING Seven higher secondary schools were covered in the limits of Greater Hyderabad Municipal Corporation, Hyderabad, India. SUBJECTS Students aged 15-19 years, n 92 for the pre-test, n 108 for test-retest and n 109 for studying the relationship between knowledge and biomarkers of Fe, retinol, ascorbic acid, α-tocopherol, folic acid and vitamin B12 status. RESULTS From an item pool of 106, thirty-one items were selected based on content validity. Statistical tools to obtain a valid and reliable questionnaire among adolescent boys and girls resulted in eighteen items with a difficulty index of 0·11-0·86, discrimination index of 0·20-0·72 and validity index (point bi-serial correlation) of 0·10-0·62. Reliability as measured by Cronbach's α was 0·71 and the intra-class correlation coefficient was 0·80. A Bland-Altman plot showed good agreement between test and retest scores. The mean response score to the eighteen-item questionnaire was 5·2 (sd 2·68). The mean values of serum retinol were significantly different (P = 0·022) between groups below (24·8 (sd 6·64) μg/dl) and above (28·0 (sd 7·67) μg/dl) the 50th percentile of knowledge score. The relationship persisted after controlling for economic status as a covariate using analysis of covariance (P = 0·018). Other micronutrients did not show any significant relationship. CONCLUSIONS A valid and reliable eighteen-item knowledge questionnaire was constructed and found to have a significant positive relationship with plasma retinol status alone.

Abstract
For several reasons, adolescence is considered as a nutritionally critical period of life. The dramatic increase in physical growth and development puts greater pressure on the need for nutrients, as it is during this period when adolescents experience a weight gain equivalent to 65% of their weight at the beginning of the period or 40% of their final weight, and a height gain equivalent to 15% of their adult height. The requirement of some of the nutrients is as high as, or higher in adolescents than in any other age groups. Moreover, adolescence is a time where the life-style and food habits are influenced by socio-cultural factors resulting in an imbalance in nutrient intake and nutrient inadequacy can result in delayed sexual maturation and can arrest or slow linear growth. With the increasing prevalence of hidden malnutrition among Indian children, adolescence can be the second opportunity to catch up growth and cover the deficits suffered during childhood and to meet the demands of physical and cognitive growth and development, provide adequate stores of energy for illnesses and pregnancy, and prevent adult onset of nutrition-related diseases. Adolescents should be recognized as a priority target group as an integral part of health promotion and optimal nutrition through balanced diet and nutrient supplementation should be promoted in conjunction with healthy eating habits and physical activity.

Abstract
Micronutrients are important in physical work capacity and therefore performance. The impact of a multi-micronutrient-fortified nutritional beverage on physical performance measures among clinically healthy school-age children was assessed in a double-blind (for test and placebo groups), placebo-controlled, randomized trial in children aged between 7 and 10.5 y (n = 300). The participants with height- and weight-for-age Z-scores between 0 and ≥ -3 were randomized to 1 of 3 study arms: fortified choco-malt beverage powder (F), matched energy equivalent unfortified placebo (U), and untreated control (C). Participants in the F and C groups were given 40 g fortified (19 key vitamins and minerals) and unfortified choco-malt beverage, respectively, daily for 120 d. Primary efficacy outcomes included endurance and aerobic capacity using a 20-m shuttle test and step test. Other physical performance measures included speed (40-m sprint), visual reaction time, maximal hand grip, and forearm static endurance. Micronutrient status included thiamin, riboflavin, folate, niacin, iron, pyridoxal phosphate, and vitamins B-12 and C. All measurements were made at baseline and the end of the intervention. There was a within-subject increase in aerobic capacity and whole body endurance (P < 0.05) accompanied by a significant improvement in the status of iron thiamin, riboflavin, pyridoxal phosphate, folate, and vitamins C and B-12 in the F group compared to the within-subject changes in the other 2 groups (P < 0.05). The study suggests that multiple micronutrient supplementation in similar populations may be beneficial in improving micronutrient status and enhancing aerobic capacity and endurance in children.

Abstract
UNLABELLED Vitamin D status of nonwestern immigrants in Europe was poor. Vitamin D status of nonwestern populations in their countries of origin varied, being either similar to the immigrant populations in Europe or higher than in European indigenous populations. Vitamin D concentrations in nonwestern immigrant populations should be improved. PURPOSE The higher the latitude, the less vitamin D is produced in the skin. Most European countries are located at higher latitudes than the countries of origin of their nonwestern immigrants. Our aim was to compare the serum 25-hydroxyvitamin D (25(OH)D) concentration of nonwestern immigrant populations with those of the population in their country of origin, and the indigenous population of the country they migrated to. METHODS We performed literature searches in the "PubMed" and "Embase" databases, restricted to 1990 and later. The search profile consisted of terms referring to vitamin D or vitamin D deficiency, prevalence or cross-sectional studies, and countries or ethnicity. Titles and abstracts were reviewed to identify studies on population-based mean serum 25(OH)D concentrations among Turkish, Moroccan, Indian, and sub-Sahara African populations in Europe, Turkey, Morocco, India, and sub-Sahara Africa. RESULTS The vitamin D status of immigrant populations in Europe was poor compared to the indigenous European populations. The vitamin D status of studied populations in Turkey and India varied and was either similar to the immigrant populations in Europe (low) or similar to or even higher than the indigenous European populations (high). CONCLUSIONS In addition to observed negative consequences of low serum 25(OH)D concentrations among nonwestern populations, this overview indicates that vitamin D status in nonwestern immigrant populations should be improved. The most efficacious strategy should be the subject of further study.

Abstract
BACKGROUND The nutritional status of school-aged children impacts their health, cognition, and subsequently their educational achievement. The school is an opportune setting to provide health and nutrition services to disadvantaged children. Yet, school-aged children are not commonly included in health and nutrition surveys. An up-to-date overview of their nutritional status across the world is not available. OBJECTIVE To provide a summary of the recent data on the nutritional status of school-aged children in developing countries and countries in transition and identify issues of public health concern. METHODS A review of literature published from 2002 to 2009 on the nutritional status of children aged 6 to 12 years from Latin America, Africa, Asia, and the Eastern Mediterranean region was performed. Eligible studies determined the prevalence of micronutrient deficiencies or child under- and overnutrition using biochemical markers and internationally accepted growth references. RESULTS A total of 369 studies from 76 different countries were included. The available data indicate that the nutritional status of school-aged children in the reviewed regions is considerably inadequate. Underweight and thinness were most prominent in populations from South-East Asia and Africa, whereas in Latin America the prevalence of underweight or thinness was generally below 10%. More than half of the studies on anemia reported moderate (> 20%) or severe (> 40%) prevalence of anemia. Prevalences of 20% to 30% were commonly reported for deficiencies of iron, iodine, zinc, and vitamin A. The prevalence of overweight was highest in Latin American countries (20% to 35%). In Africa, Asia, and the Eastern Mediterranean, the prevalence of overweight was generally below 15%. CONCLUSIONS The available data indicate that malnutrition is a public health issue in school-aged children in developing countries and countries in transition. However, the available data, especially data on micronutrient status, are limited. These findings emphasize the need for nutrition interventions in school-aged children and more high-quality research to assess nutritional status in this age group.

Abstract
Background Anemia and micronutrient deficiencies are common among Indian schoolchildren. However, past studies have narrowly focused on only a few micronutrients and have not carefully evaluated the association between sociodemographic factors and nutritional status of schoolchildren. Objective To assess the nutritional status of schioolchildren in Himalayan villages of India and to determine the relationships between their nutritional status, intestinal helminth infection, and sociodemographic characteristics. Methods A random sample of 499 children 6 to 10 years of age from 20 public primary schools was selected. Household sociodemographic data and morbidity data on children were collected through interviews with their caretakers. Height and weight were measured, and venous blood was drawn for assessment of hemoglobin, serum ferritin, soluble transferrin receptor, retinol, zinc, folic acid, vitamin B12, and C-reactive protein. Stool samples were analyzed for parasitic infections. Results Underweight, stunting, and wasting were present in 60.9%, 56.1%, and 12.2% of schoolchildren, respectively. Anemia, iron-deficiency anemia, and low serum concentrations of ferritin, zinc, retinol, folate, and vitamin B12 were found in 36.7%, 10.2%, 24.1%, 57.1%, 56.1%, 67.9%, and 17.4% of the children, respectively. One-fifth of the children had intestinal parasites. Being underweight was associated with lower household wealth ( p < .05). Helminth infection was associated with stunting, anemia, and low serum retinol ( p < .05). Living at higher altitude was associated with low serum levels of ferritin, retinol, and vitamin B12. There were no associations between any sociodemographic variables and serum zinc or folate. Conclusions Growth impairment and micronutrient deficiencies are prevalent among schoolchildren in Himalayan villages of India.

Abstract
Anemia and micronutrient deficiencies are common among Indian schoolchildren. We assessed the effectiveness of micronutrient fortification of meals cooked and fortified at school on anemia and micronutrient status of schoolchildren in Himalayan villages of India. In this placebo-controlled, cluster-randomized study, 499 schoolchildren (6-10 y) received either multiple micronutrients (treatment group) or placebo (control group) as part of school meals (6 d/wk) for 8 mo. Both groups were dewormed at the beginning of the study. The micronutrient premix provided 10 mg iron, 375 microg vitamin A, 4.2 mg zinc, 225 microg folic acid, and 1.35 microg vitamin B-12 for each child per day (approximately 75% recommended dietary allowance). Blood samples drawn before and after the intervention were analyzed for hemoglobin, ferritin, retinol, zinc, folate, and vitamin B-12. Baseline prevalence of anemia (37%), iron deficiency anemia (10%), low serum ferritin (24%), retinol (56%), zinc (74%), folate (68%), and vitamin B-12 (17%) did not differ between groups. Postintervention, fewer in the treatment group had lower serum retinol [odds ratio (OR) (95% CI): 0.57 (0.33-0.97)] and folate [OR (95% CI): 0.47 (0.26-0.84)] than the control group. The serum vitamin B-12 concentration decreased in both groups, but the magnitude of change was less in the treatment than in the control group (P < 0.05). Total body iron (TBI) increased in both groups; however, the change was greater in the treatment than in the control group (P < 0.05). Micronutrient fortification of school meals by trained school personnel was effective in improving vitamin A, folate, and TBI status while also reducing the magnitude of a decrease in vitamin B-12 status.

Abstract
AIM To study the effect of weaning biscuits supplementation of the nutritional parameters and cognitive performance of the selected children. METHODS Three primary schools situated in Salem District, Tamilnadu, India were selected. A total number of 150 school children, 61 from primary school I, 46 from primary school II and 43 from primary school III comprised the study sample. About 80 primary school children with Grade II malnutrition were selected for the experimental study. Home diet without any supplementation was followed by Group I (n=20, control group), potato flour biscuit was supplemented to Group II (n=20), wheat biscuits was given to Group III (n=20) and ragi biscuits were given to Group IV (n=20) for the period of 3 months. Parameters like anthropometric measurements, hemoglobin content clinical picture and cognitive performance were analyzed before and after supplementation. RESULTS Results about Group I (control group) showed no significant difference in height, weight and clinical picture and cognitive performance after three months on their home diet. In Group II, III and IV significant increase in all the above parameters was noticed. More increase was found in Group II children supplemented with potato flour biscuits for a period of 3 months. About cognitive performance better results was obtained in Group II followed by Group III (supplemented with wheat biscuits) and Group IV (supplemented with ragi biscuits). Least was obtained by control group children who are in their home diet. CONCLUSION All these observations evident that if such weaning biscuits made with potato flour, wheat and Ragi can form a daily ingredient in their diets, it will bring out better all round development of the children.

Abstract
Staple food crops, in particular cereal grains, are poor sources of key mineral nutrients. As a result, the world's poorest people, generally those subsisting on a monotonous cereal diet, are also those most vulnerable to mineral deficiency diseases. Various strategies have been proposed to deal with micronutrient deficiencies including the provision of mineral supplements, the fortification of processed food, the biofortification of crop plants at source with mineral-rich fertilizers and the implementation of breeding programs and genetic engineering approaches to generate mineral-rich varieties of staple crops. This review provides a critical comparison of the strategies that have been developed to address deficiencies in five key mineral nutrients-iodine, iron, zinc, calcium and selenium-and discusses the most recent advances in genetic engineering to increase mineral levels and bioavailability in our most important staple food crops.

Abstract
OBJECTIVE To assess the nutritional status of adolescent girls in a slum community of Urban Health Center, Panangal. METHODS A community-based cross-sectional study was carried out over a period of two months. 223 adolescent girls of age 10-18 years were selected randomly. Data was collected by interviewing the adolescent girls using predesigned, pre tested, semi-structured schedule. Parents interview was taken whenever necessary. Anthropometric measurements were recorded using standardized methodology as recommended by World Health Organization (WHO). Standard operational definitions were used. Various statistical applications like percentiles, mean, standard deviation and proportions were used for analysis of the data. RESULTS Overall prevalence of stunting was found to be 47% and 28.3% as per NCHS and Indian standards respectively. Prevalence of underweight was 42.6% and 22.9% as per NCHS and Indian standards respectively. Prevalence of thinness was 20.6% as per Indian standards. CONCLUSION It is concluded that there is a high prevalence of under nutrition among adolescent girls in this slum community. Health education and nutrition interventions are needed on priority basis.

Abstract
Pediatrics deals with promotion of health and well being of children and not merely diagnosis and treatment of their diseases. Children are truly the foundation of a society because healthy children grow to become healthy and strong adults who can actively participate in the developmental activities of a nation. Health and well being of children is intimately linked with the health, nutrition, education and awareness of their mothers. In order to improve child health and survival, it is therefore important to provide a life-cycle approach for the care of girl children with focus on equal opportunities for their nutrition (from birth through infancy, childhood, adolescence, pregnancy and lactation), optimal health care, education, dignity, empowerment, status and say in society. Every child must be viewed in totality - body, mind, heart and soul, and not in isolation but in context with the dynamics of their ecology, family, friends, teachers and society. We should treat the child and not his disease or laboratory reports. And every contact with the family should be effectively harnessed to provide "holistic care" and not mere "cure". We must give advice regarding life style changes, importance of personal hygiene, promotion of breast feeding, provision of safe environment, personal hygiene, optimal nutrition, immunizations and prevention of accidents. We should try to establish a rapport with the child and his parents to provide them emotionai support and win their faith, trust and confidence. We should make sincere efforts to become knowledgeable, upto-date and a rational physician to practice evidence-based pediatrics. Above all, we must strive to master the sublime art of medicine and acquire the divine gift of healing. And we should not allow technology to further dehumanize medicine!

Abstract
Inadequate nutrition and acute lower respiratory infection (ALRI) are overlapping and interrelated health problems affecting children in developing countries. Based on a critical review of randomized trials of the effect of nutritional interventions on ALRI morbidity and mortality, we concluded that: (1) zinc supplementation in zinc-deficient populations prevents about one-quarter of episodes of ALRI, which may translate into a modest reduction in ALRI mortality; (2) breastfeeding promotion reduces ALRI morbidity; (3) iron supplementation alone does not reduce ALRI incidence; and (4) vitamin A supplementation beyond the neonatal period does not reduce ALRI incidence or mortality. There was insufficient evidence regarding other potentially beneficial nutritional interventions. For strategies with a strong theoretical rationale and probable operational feasibility, rigorous trials with active clinical case-finding and adequate sample sizes should be undertaken. At present, a reduction in the burden of ALRI can be expected from the continued promotion of breastfeeding and scale-up of zinc supplementation or fortification strategies in target populations.

Abstract
The leaves and pods of the drumstick tree are used as food and medicine in some Asian and African countries. Although relatively high concentrations of beta-carotene and lutein have been reported in the leaves, the bioavailability of these carotenoids from this source is unknown. We have analyzed the digestive stability and bioaccessibility of carotenoids in fresh and lyophilized drumstick leaves using the coupled in vitro digestion/Caco-2 cell model. Beta-carotene and lutein were stable during simulated gastric and small intestinal digestion. The efficiency of micellarization of lutein during the small intestinal phase of digestion exceeded that of beta-carotene. Addition of peanut oil (5% vol/wt) to the test food increased micellarization of both carotenoids, and particularly beta-carotene. Caco-2 cells accumulated beta-carotene and lutein from micelles generated during digestion of drumstick leaves in a time- and concentration-dependent manner. The relatively high bioaccessibility of beta-carotene and lutein from drumstick leaves ingested with oil supports the potential use of this plant food for improving vitamin A nutrition and perhaps delaying the onset of some degenerative diseases such as cataracts.

Abstract
OBJECTIVE We evaluated the effect of a micronutrient-fortified beverage on growth and morbidity in apparently healthy schoolchildren. METHODS This was a double-blind, placebo-controlled, matched-pair, cluster, randomized study in semi-urban middle-income residential schoolchildren aged 6 to 16 y. Anthropometrics (height and weight), clinical symptoms of deficiency, and morbidity data were collected at baseline in the supplemented group (n = 446 in 10 grades) and the placebo group (n = 423 in 10 grades) and after 14 mo of supplementation (n = 355 in the supplement group and n = 340 in the placebo group from nine pairs). RESULTS After 14 mo of supplementation, there was a significant increase in mean increments of height and weight z scores of -0.04 and 0.02, respectively, in the supplemented group compared with -0.14 and -0.09 in the placebo group. Velocity of weight (3.56 versus 3.00) was significantly (P < 0.01) higher with supplementation. Although there were no differences in the incidence of common childhood diseases such as fever, cough and cold, diarrhea, and ear infections elicited for a reference period of 1 mo at every quarterly follow-up examination, the mean duration of illness (calculated per person per year) was significantly shorter (5.0 d) in the supplemented group than in the placebo group (7.4 d). CONCLUSIONS The micronutrient-fortified beverage was beneficial in promoting growth and decreasing duration of common illnesses among middle-class residential schoolchildren who had adequate energy and protein intakes.

Abstract
OBJECTIVE We evaluated the effect of a micronutrient-fortified beverage on mental function in schoolchildren. METHODS This double-blind, placebo-controlled, matched-pair, cluster, randomized feeding trial assessed baseline before supplementation and after 14 mo in a cohort of 608 children aged 6 to 15 y who received a micronutrient-fortified beverage or placebo. Children in two classes (clusters) in each of nine grades were assessed for intelligence, attention and concentration, memory, and school achievement. RESULTS Mean intelligence quotient scores of the micronutrient-fortified beverage group and the placebo group at baseline and final follow-up were not significantly different. Mean verbal and performance scores and increments were also not different. After supplementation, attention-concentration increment scores of the micronutrient group were significantly higher (P < 0.05) than those of the placebo group. Mean and incremental scores of the supplemented group on the memory scale were not significantly different from those of the placebo group. CONCLUSIONS Supplementation with a beverage fortified with a range of micronutrients significantly improved attention-concentration over 14 mo, but not intelligence quotient, memory, or school achievement among middle-income schoolchildren.

Abstract
OBJECTIVE We tested the hypothesis that supplementation with a micronutrient-fortified beverage improves micronutrient status and physical and mental development in apparently healthy schoolchildren. METHODS The study was carried out in middle-income students in two residential schools that catered to children from a semi-urban population near Hyderabad, India. Included were 869 children who were 6 to 16 y of age in grades 1 to 10. Because children at each grade were distributed across two classrooms (clusters) and were homogeneous, each grade was considered to consist of a matched pair. There were thus 10 pairs available for the study. Classes in each grade were randomized to receive a micronutrient-enriched beverage or a placebo without added micronutrients. The study was double blinded and the duration was 14 mo, with supervised feeding of the micronutrient-enriched beverage. The effect of the micronutrients on the outcome variables growth, biochemical status, mental function, and bone health were assessed. RESULTS The number of matched pairs varied between seven and eight, and the required number of children per treatment group ranged from 32 in the case of bone heath to 177 for body weight. The power of the outcome variables ranged from 74% to 100% and was adequate for successful pairing. The effect assessed at the end of supplementation showed that the intervention was beneficial. CONCLUSIONS Designing an intervention, choosing outcome variables, and implementing the protocol in a typical Indian school setting were achieved.
