abstract: Iron deficiency anaemia is a most common micronutrient deficiency affecting mostly the low socioeconomic population s of the developing world . The objective of this study was to evaluate the feasibility of iron fortification of household drinking water to prevent iron deficiency anaemia among members of the low socioeconomic families of Southern Brazil . A total of 21 low socioeconomic families representing 88 subjects including 1 - 6 years old children whose haemoglobin level was between 10 and 12 g/dl were selected to participate in this study . Nine families in the control group were supplied with placebo solution and 12 families in the experimental group were supplied iron solution with ascorbic acid to be added to their domestic drinking water over a period of 4 months . The feasibility and acceptability of iron fortified drinking water was assessed through home visits and question naires . Blood sample s were collected at the beginning and after 4 months of the study for the determination of haemoglobin and serum ferritin levels . The results of this study indicated that iron fortified drinking water was well received by the low socioeconomic families and that it was effective in improving the haemoglobin and serum ferritin levels . It can be concluded from this study that iron fortification of household drinking water is a simple and effective alternative for developing countries along with other technological approaches to iron fortification of foods OBJECTIVES This study hypothesized that besides iron deficiency , intestinal parasites infection is also a determinant of anemia in schoolchildren in rural Vietnam . METHODS 400 primary schoolchildren from 20 primary schools in Tam Nong district , a poor rural area in Vietnam , were r and omly selected from enrollment lists .  Venous blood ( 5ml ) was collected in a cross sectional study and analyzed for hemoglobin ( Hb ) , serum ferritin ( SF ) , serum transferrin receptor ( TfR ) , serum C-reactive protein ( CRP ) and total immunoglobulin E ( IgE ) .  Stools sample s were examined for hookworm , Trichuris , and Ascaris infection . Logistic regression was used to assess the effect of intestinal parasites on anemia . RESULTS The prevalence of anemia ( Hb < 115g/l ) was 25 % . Iron deficiency ( TfR > 8.5mg/L ) occurred in 2 % of the children . The prevalence of intestinal parasites was 92 % with the highest prevalence for Trichuris ( 76 % ) and Ascaris ( 71 % ) . More than 30 % and 80 % of the children showed an elevated CRP ( > or = 8 mg/L ) and IgE ( > 90 IU/ml ) concentration . Anemia status was borderline significantly associated with SF and not associated with TfR and CRP . The prevalence odds ratio for Trichuris infection was 1.96 ( 95 % CI 1.07 - 3.59 ) and 2.00 ( 95 % CI 1.08 - 3.65 ) with iron deficiency reflected by TfR and SF , respectively . CONCLUSION Anemia is highly prevalent among schoolchildren in Vietnam but may not be associated with iron deficiency . Trichuris infection is associated with a doubled risk of anemia , not mediated through iron deficiency . Chronic infection may play a role in anemia , but needs further investigation BACKGROUND Children participating in the Integrated Child Development Service ( ICDS ) in India have high rates of iron and vitamin A deficiency . OBJECTIVE The objective was to assess the efficacy of a premix fortified with iron and vitamin A and added at the community level to prepared khichdi , a rice and dal mixture , in increasing iron and vitamin A stores and decreasing the prevalence of iron deficiency , anemia , and vitamin A deficiency . DESIGN This cluster , r and omized , double-blind , controlled trial was initiated in 30 Anganwadi centers ( daycare centers ) in West Bengal state , India . Children aged 36 - 66 mo ( n = 516 ) attending village-based ICDS centers were r and omly assigned to receive either a fortified or a nonfortified premix for 24 wk . Blood was drawn at 0 and 24 wk by venipuncture for the measurement of hemoglobin , serum ferritin , and serum retinol . RESULTS The change in the hemoglobin concentration of anemic children was significantly different between fortified and nonfortified khichdi groups ( P < 0.001 ) . Prevalence rates of anemia , iron deficiency , and iron deficiency anemia were significantly lower after 24 wk in the fortified-khichdi group than in the nonfortified-khichdi group ( P < 0.001 ) . There were no significant differences in serum retinol concentrations or in the prevalence of vitamin A deficiency between the fortified- and nonfortified-khichdi groups . CONCLUSION A premix fortified with iron , vitamin A , and folic acid and added to supplementary food at the community level can be effective at increasing iron stores and reducing the prevalence of iron deficiency and anemia BACKGROUND Iron fortification of rice could be an effective strategy for reducing iron deficiency anemia in South Asia . OBJECTIVE We aim ed to determine whether extruded rice grains fortified with micronized ground ferric pyrophosphate ( MGFP ) would increase body iron stores in children . DESIGN In a double-blind , 7-mo , school-based feeding trial in Bangalore , India , iron-depleted , 6 - 13-y-old children ( n = 184 ) were r and omly assigned to receive either a rice-based lunch meal fortified with 20 mg Fe as MGFP or an identical but unfortified control meal . The meals were consumed under direct supervision , and daily leftovers were weighed . All children were dewormed at baseline and at 3.5 mo . Iron status and hemoglobin were measured at baseline , 3.5 mo , and 7 mo . RESULTS At baseline , the prevalences of iron deficiency and iron deficiency anemia in the total sample were 78 % and 29 % , respectively . After 7 mo of feeding , there was a significant increase in body iron stores in both study groups ( P < 0.001 ) , with a greater increase in the iron group than in the control group ( P < 0.05 ) . There was a significant time x treatment interaction for iron deficiency , which fell from 78 % to 25 % in the dewormed iron group and from 79 % to 49 % in the dewormed control group . Iron deficiency anemia decreased from 30 % to 15 % ( NS ) in the iron group but remained virtually unchanged in the control group ( 28 % and 27 % ) . In sensory tests , the MGFP-fortified rice ( fortified at 3 and 5 mg Fe/100 g ) was indistinguishable from natural rice , in both cooked and uncooked form . CONCLUSIONS Extruded rice fortified with MGFP has excellent sensory characteristics . Fed in a school lunch meal , it increases iron stores and reduces the prevalence of iron deficiency in Indian children A r and omized , double-blind , placebo-controlled iron supplementation trial was conducted in Kenya to examine the effect of iron supplements on appetite and growth in 87 primary school children .  Sustained-release ferrous sulfate ( 150 mg ) or placebo tablets were provided daily at school for 14 wk . Prior to tablet administration , baseline anthropometry , iron nutritional status ( hemoglobin and serum ferritin ) , parasitic infections and clinical indicators of morbidity were measured . A baseline appetite test was conducted twice on each child by quantitatively measuring the ad libitum consumption of a midmorning snack . In addition , each child was asked for a subjective assessment of his or her appetite . Follow-up exams and appetite tests were identical to those at baseline . Findings indicated that provision of iron supplements result ed in improved growth and improved appetite ( in terms of both energy intake of the snack and child report of appetite ) as compared with children receiving the placebo . The increased energy intake from the snack was 10 % of the daily estimated energy intake for children of this same age group living elsewhere in Kenya . Further research into the underlying physiological mechanisms may shed light on the relationship between iron nutritional status and appetite BACKGROUND Iron deficiency anemia is the most prevalent nutrition problem in young children . One possible strategy to prevent iron deficiency anemia in this population group is the fortification of affordable food . OBJECTIVE This study was design ed to assess whether iron-fortified c and ies can improve iron status and are acceptable to children aged 4 - 6 y. DESIGN A double-blind , placebo-controlled intervention study was conducted in Jakarta , INDONESIA : The children were r and omly assigned to 1 of 2 treatment groups : a fortified group ( n = 57 ) and a placebo group ( n = 60 ) . Every week for 12 wk , 30 g ( 10 pieces ) c and y was given to the children . The c and y given to the fortified group contained 1 mg elemental Fe/g and very small amounts of other vitamins and minerals . RESULTS The hemoglobin concentration of the fortified group increased by 10.2 g/L ( 95 % CI : 8.3 , 12 g/L ) whereas that of the placebo group increased by 4.0 g/L ( 2.0 , 6.0 g/L ; P < 0.001 ) . Anemia prevalence decreased from 50.9 % at the start of the intervention to 8.8 % after 12 wk of intervention in the fortified group ( P < 0.001 ) and from 43.3 % to 26.7 % in the placebo group ( P < 0.05 ) . After 12 wk of intervention , the serum ferritin concentration was 71 % higher than at baseline in the fortified group and 28 % higher in the placebo group ( P < 0.001 ) . Acceptability of the iron-fortified c and ies was good . The per capita cost of the supplement was approximately US$ 0.96 - 1.20 for the 12 wk of intervention . CONCLUSION Iron-fortified c and ies were effective for improving the iron status  of young children and might be an affordable way to combat iron deficiency in children of low-to-middle income groups OBJECTIVE We assessed the effect of a daily intake of a micronutrient-fortified beverage for 14 mo on indicators of biochemical status of important micronutrients in schoolchildren . METHODS A double-blind , placebo-controlled , matched-pair , cluster , r and omization study design was used . Biochemical indicators of micronutrient status were evaluated at baseline and at the end of 14 mo on a sub sample in nine matched pairs . Prevalence ( percentage ) of sub clinical deficiency , mean , and mean increments of each indicator were compared between supplemented and placebo groups . RESULTS Extent of inadequacy at baseline was more or less 100 % for folic acid , 65 % for vitamins B2 and B6 , and 55 % for vitamins C and A. Prevalence of anemia among subjects was 55 % , with inadequacy of vitamin B12 being 40 % and that of vitamin D being 30 % . No subject had inadequacy of iodine based on urinary iodine . Supplementation of a micronutrient-enriched beverage for 14 mo significantly improved the status of many of the nutrients . The effect was significant with respect to vitamins A , B2 , and B12 , folic acid , vitamin D , parathyroid hormone , and thyroid-stimulating hormone in children who received the supplement compared with those who received only placebo .  Hemoglobin status improved only in children who had anemia in the supplemented group . CONCLUSIONS Prevalence of multiple sub clinical micronutrient deficiencies are high in middle-income Indian school children . Daily consumption of a micronutrient-enriched beverage had positive effects that were confined to those nutrients that were inadequate at baseline OBJECTIVE To evaluate the long-term effect on micronutrient status of a beta-carotene- , iron- and iodine-fortified biscuit given to primary school children as school feeding . DESIGN Children receiving the fortified biscuit were followed in a longitudinal study for 2.5 years ( n = 108 ) ; in addition , cross-sectional data from three subsequent surveys conducted in the same school are reported . SETTING A rural community in KwaZulu-Natal , South Africa . SUBJECTS Children aged 6 - 11 years attending the primary school where the biscuit was distributed . RESULTS There was a significant improvement in serum retinol , serum ferritin , haemoglobin , transferrin saturation and urinary iodine during the first 12 months of the biscuit intervention . However , when the school reopened after the summer holidays , all variables , except urinary iodine , returned to pre-intervention levels . Serum retinol increased again during the next 9 months , but was significantly lower in a subsequent cross-sectional survey carried out directly after the summer holidays ; this pattern was repeated in two further cross-sectional surveys . Haemoglobin gradually deteriorated at each subsequent assessment , as did serum ferritin ( apart from a slight increase at the 42-month assessment at the end of the school year ) . CONCLUSIONS This study has shown that fortification of a biscuit with beta-carotene at a level of 50 % of the Recommended Dietary Allowance ( RDA ) was enough to maintain serum retinol concentrations from day to day , but not enough to sustain levels during the long school holiday break . Other long-term solutions , such as local food production programmes combined with nutrition education , should also be examined . The choice of the iron compound used as fortificant in the biscuit needs further investigation AIMS To assess the quality of r and omized controlled trials ( RCTs ) published in Neurourology and Urodynamics ( NAU ) by using three types of analytical tools . METHODS MEDLINE was used to extract RCTs from original articles published in the NAU from 1993 to 2012 . The relationship between the number of articles and RCTs with time and that between various factors and the quality of RCTs were analyzed . To analyze the quality of the RCTs , the time period was divided into four sections and three tools were applied ( e.g. , the Jadad scale , van Tulder scale , and Cochrane Collaboration Risk of Bias Tool [ CCRBT ] ) . RESULTS Among the 1,957 original articles , 93 ( 4.75 % ) were RCTs . The ratio between the number of NAU and RCTs over time increased . The Jadad score for years 1993 - 1997 was 3.25 ± 1.71 , 1998 - 2002 was 2.10 ± 0.74 , 2003 - 2007 was 2.09 ± 1.12 , and 2008 - 2012 was 2.80 ± 1.09 ( P = 0.014 ) . The van Tulder scales were 6.25 ± 3.10 , 4.40 ± 1.65 , 4.97 ± 1.99 , and 5.93 ± 1.98 , respectively ( P = 0.055 ) . The CCRBT identified a low risk of bias in 1 ( 25 % ) , 0 ( 0 % ) , 1 ( 2.86 % ) , and 5 ( 11.36 % ) articles , respectively . Trials with allocation concealment , Institutional review board ( IRB ) approval , and blinded studies had significantly higher quality than others . CONCLUSIONS The quantitative increase of RCT presented in NAU over time was observed but there was no definite qualitative improvement . Effort is required to improve the quality of RCTs published in NAU from the design step OBJECTIVE . Chronic lead poisoning and iron deficiency are concentrated in urban children from lower socioeconomic strata , and both impair neurocognitive development . Our study objective was to determine if iron fortification reduces blood lead levels in urban , lead-exposed , iron-deficient children in Bangalore , India . DESIGN , SETTING , AND PARTICIPANTS . A r and omized , double-blind , controlled school-based feeding trial was done in 5- to 13-year-old iron-deficient children ( n = 186 ) . At baseline , a high prevalence of lead poisoning was found in the younger children . Subsequently , all 5- to 9-year-old children participating in the trial ( n = 134 ) were followed to determine if iron fortification would affect their blood lead levels . INTERVENTION . Children were dewormed and fed 6 days/week for 16 weeks either an iron-fortified rice meal ( ∼15 mg of iron per day as ferric pyrophosphate ) or an identical control meal without added iron . Feeding was directly supervised and compliance monitored . OUTCOME MEASURES . Hemoglobin , serum ferritin , C-reactive protein , transferrin receptor , zinc protoporphyrin , and blood lead concentrations were measured . RESULTS . The prevalence of iron deficiency was significantly reduced in the iron group ( from 70 % to 28 % ) compared with the control group ( 76 % to 55 % ) . There was a significant decrease in median blood lead concentration in the iron group compared with the control group . The prevalence of blood lead levels ≥10 μg/dL was significantly reduced in the iron group ( from 65 % to 29 % ) compared with the control group ( 68 % to 55 % ) . CONCLUSIONS . Our findings suggest providing iron in a fortified food to lead-exposed children may reduce chronic lead intoxication . Iron fortification may be an effective and sustainable strategy to accompany environmental lead abatement BACKGROUND Sodium iron edetic acid ( NaFeEDTA ) might be a more bioavailable source of iron than electrolytic iron , when added to maize flour . We aim ed to assess the effect , on children 's iron status , of consumption of whole maize flour fortified with iron as NaFeEDTA or electrolytic iron . METHODS 516 children , aged 3 - 8 years , from four schools in Marafa , Kenya , were r and omly assigned to four groups . All were given the same amount of porridge five times a week . The porridge for one group was made from unfortified whole maize flour ; for the other three groups it was fortified with either high-dose NaFeEDTA ( 56 mg/kg ) , low-dose NaFeEDTA ( 28 mg/kg ) , or electrolytic iron ( 56 mg/kg ) . Concentrations of haemoglobin , plasma ferritin , and transferrin receptor were analysed in sample s taken at baseline and at the end of the 5-month intervention . The primary outcome was iron-deficiency anaemia . We analysed data on an intention-to-treat basis . This trial is registered with Clinical Trials.gov , number NCT00386074 . FINDINGS The prevalence of iron-deficiency anaemia in children given unfortified flour was 10 % . Compared with placebo , the prevalence of iron-deficiency anaemia in children given flour fortified with high-dose NaFeEDTA , low-dose NaFeEDTA , and electrolytic iron changed by -89 % ( 95 % CI -97 % to -49 % ) , -48 % ( -77 % to 20 % ) , and 59 % ( -18 % to 209 % ) , respectively . Consumption of high-dose NaFeEDTA improved all measured iron-status indicators . Low-dose NaFeEDTA decreased the prevalence of iron deficiency but did not noticeably change the prevalence of anaemia . Electrolytic iron did not improve any of these iron-status indicators .  Children who were iron-deficient at baseline benefited more from high-dose and low-dose NaFeEDTA than those with sufficient iron at baseline . INTERPRETATION Consumption of whole maize flour fortified with NaFeEDTA caused modest , dose-dependent improvements in children 's iron status . Fortification with electrolytic iron did not improve their iron status . Therefore , in high-phytate flours , NaFeEDTA is more suitable than electrolytic iron for supplementation of iron in the diet Food fortification is an important long-term strategy for addressing micronutrient deficiencies . Finding the ideal Fe fortification compound , however , remains a challenge . In the present study the effect of ferrous bisglycinate as fortificant in brown bread was compared with that of electrolytic Fe among Fe-deficient school children in a r and omised controlled trial . Children ( n 160 ) , aged 6 - 11 years , with serum ferritin < 20 microg/l , were r and omly assigned to one of three treatment categories : ( i ) st and ard unfortified bread ; ( ii ) bread with electrolytic Fe as fortificant ; and ( iii ) bread with ferrous bisglycinate as fortificant . Each child received four slices of bread ( 120 g ) on school days , which supplied an average of 3.66 mg elemental Fe per intervention day for 137 d ( 2.52 mg/d for 75 d and 5.04 mg/d for 62 d ) over a period of 7.5 months . Hb , serum ferritin , serum Fe and transferrin saturation were measured at baseline and at the end of the intervention . Significant treatment effects were observed for Hb ( P = 0.013 ) , serum Fe ( P = 0.041 ) and transferrin saturation ( P = 0.042 ) in the ferrous bisglycinate group , but not in the electrolytic Fe group . There were no significant intervention effects for serum ferritin in either treatment group . Overall , ferrous bisglycinate as Fe fortificant in brown bread performed better than electrolytic Fe in a group of Fe-deficient school children over a period of 7.5 months The aim of this study was to determine the iron status of infants who consumed porridge cooked in water with added ferrous sulphate .  A total of 234 infants , aged 6 - 12 months , were recruited from 36 nurseries in the Democratic Peoples Republic of Korea ( DPRK North Korea ) and r and omly divided into iron ( Fe ) and placebo groups . At baseline , almost half the children had Hb<110 g/L and no significant differences between the two groups were found with regard to hemoglobin concentration and anemia prevalence . The Fe group received rice porridge fortified with 10 mg of iron ( as ferrous sulfate ) per day , added to the water in which the rice was cooked and the placebo group non-fortified cereal for 6 months . After which , the hemoglobin ( Hb ) , serum ferritin ( SF ) and packed cell volume ( PCV ) were measured and it was found that the proportion of children with anemia ( Hb<110 g/L ) was lower ( 24.3 % v 48.1 % p<0.01 ) , the Hb levels ( 117.6 g/L v 109.8 g/L p<0.001 ) and serum ferritin were higher ( 40.7 v 26.8 mcg/L p<0.001 ) ; and iron deficiency anemia ( Hb<110 g/L , SF<12 mcg/L ) was lower in the Fe group ( 3 % v 22 % p<0.001 ) when compared to the placebo group . Ferrous sulphate , added to the water in which rice was cooked , lowered the prevalence of iron deficiency anemia of infants in the DPRK with no adverse reactions . This simple fortification would be suitable as a nationwide program in the DPRK and other countries with large infant nurseries Background Multiple micronutrient deficiencies are highly prevalent among preschool children and often lead to anemia and growth faltering . Given the limited success of supplementation and health education programs , fortification of foods could be a viable and sustainable option . We report results from a community based double-masked , r and omized trial among children 1–4 years evaluating the effects of micronutrients ( especially of zinc and iron ) delivered through fortified milk on growth , anemia and iron status markers as part of a four group study design , running two studies simultaneously . Methods and Findings Enrolled children ( n = 633 ) were r and omly allocated to receive either micronutrients fortified milk ( MN = 316 ) or control milk ( Co = 317 ) . Intervention of MN milk provided additional 7.8 mg zinc , 9.6 mg iron , 4.2 µg selenium , 0.27 mg copper , 156 µg vitamin A , 40.2 mg vitamin C , and 7.5 mg vitamin E per day ( three serves ) for one year . Anthropometry was recorded at baseline , mid- and end- study . Hematological parameters were estimated at baseline and end- study . Both groups were comparable at baseline . Compliance was over 85 % and did not vary between groups . Compared to children consuming Co milk , children consuming MN milk showed significant improvement in weight gain ( difference of mean : 0.21 kg/year ; 95 % confidence interval [ CI ] 0.12 to 0.31 , p<0.001 ) and height gain ( difference of mean : 0.51 cm/year ; 95 % CI 0.27 to 0.75 , p<0.001 ) . Mean hemoglobin ( Hb ) ( difference of 13.6 g/L ; 95 % CI 11.1 to 16.0 , p<0.001 ) and serum ferritin levels ( difference of 7.9 µg/L ; 95 % CI 5.4 to 10.5 , p<0.001 ) also improved . Children in MN group had 88 % ( odds ratio = 0.12 , 95 % CI 0.08 to 0.20 , p<0.001 ) lower risk of iron deficiency anemia . Conclusions / Significance Milk provides an acceptable and effective vehicle for delivery of specific micronutrients , especially zinc and iron . Micronutrient bundle improved growth and iron status and reduced anemia in children 1–4 years old . Trial Registration Clinical Trials.gov OBJECTIVE To determine whether clinical trials originating in certain countries always have positive results . DATA SOURCES Abstract s of trials from Medline ( January 1966-June 1995 ) . STUDY SELECTION Two separate studies were conducted . The first included trials in which the clinical outcome of a group of subjects receiving acupuncture  was compared to that of a group receiving placebo , no treatment , or a nonacupuncture intervention . In the second study , r and omized or controlled trials of interventions other than  acupuncture  that were published in China , Japan , Russia/USSR , or Taiwan were compared to those published in Engl and . DATA EXTRACTION Blinded review ers determined inclusion and outcome and separately classified each trial by country of origin . DATA SYNTHESIS In the study of acupuncture  trials , 252 of 1085 abstract s met the inclusion criteria . Research conducted in certain countries was uniformly favorable to acupuncture ; all trials originating in China , Japan , Hong Kong , and Taiwan were positive , as were 10 out of 11 of those published in Russia/USSR . In studies that examined interventions other than acupuncture , 405 of 1100 abstract s met the inclusion criteria . Of trials published in Engl and , 75 % gave the test treatment as superior to control . The results for China , Japan , Russia/USSR , and Taiwan were 99 % , 89 % , 97 % , and 95 % , respectively . No trial published in China or Russia/USSR found a test treatment to be ineffective . CONCLUSIONS Some countries publish unusually high proportions of positive results . Publication bias is a possible explanation . Research ers undertaking systematic review s should consider carefully how to manage data from these countries A previous longitudinal three-country study in Egypt , Kenya and Mexico found significant positive associations between intake of animal source foods ( ASF ) and growth , cognitive development and physical activity . To test for a causal relationship , a controlled school feeding intervention study was design ed to test the hypotheses that ASF would improve micronutrient status , growth and cognitive function in Kenyan primary school children . Twelve rural Kenyan schools with 554 children were r and omized to four feeding interventions using a local vegetable stew as the vehicle . The groups were design ated as Meat , Milk , Energy and Control , who received no feedings . Feeding was carried out on school days for seven terms during 21 mo . Preintervention baseline measures included nutritional status , home food intake , anthropometry , biochemical measures of micronutrient status , malaria , intestinal parasites , health status and cognitive and behavioral measures . The measurements of each child were repeated at intervals over 2 y. Baseline data revealed stunting and underweight in approximately 30 % of children and widespread inadequate intakes and /or biochemical evidence of micronutrient deficiencies , particularly of iron , zinc , vitamins A and B-12 , riboflavin and calcium . Little or no ASF were eaten and fat intake was low . Malaria was present in 31 % of children , and hookworm , amebiasis and giardia were widely prevalent . The outcomes measured were rates of change or increase during the intervention in cognitive function , growth , physical activity and behavior and micronutrient status . Hierarchical linear r and om effects modeling was used for analysis of outcomes INTRODUCTION Iron deficiency is widespread in the developing world and is especially common in young children who live on the Indian subcontinent . Supplementation with iron and folic acid alleviates severe anaemia and enhances neurodevelopment in deficient population s , but little is known about the risks of mortality and morbidity associated with supplementation . METHODS We did a community-based , cluster-r and omised , double-masked , placebo-controlled , 2x2 factorial trial in children aged 1 - 36 months and residing in southern Nepal . We r and omly assigned children daily oral supplementation to age 36 months with : iron ( 12.5 mg ) and folic acid ( 50 microg ; n=8337 ) , zinc alone ( 10 mg ) , iron , folic acid , and zinc ( n=9230 ) , or placebo ( n=8683 ) ; children aged 1 - 11 months received half the dose . Our primary outcome measure was all-cause mortality , and our secondary outcome measures included cause-specific mortality and incidence and severity of diarrhoea , dysentery , and acute respiratory illness . Analyses were by intention to treat . This study is registered at , number NCT00109551 . FINDINGS The iron and folic acid-containing groups of the study were stopped early in November , 2003 , on the recommendation of the data and safety monitoring board ; mortality in these groups did not differ from placebo and there was low power to detect positive or negative effects by the time enrollment was completed . We continued to enroll children to the placebo and zinc alone groups . 25,490 children participated and analyses are based on 29,097.3 person-years of follow-up . There was no difference in mortality between the groups who took iron and folic acid without or with zinc when compared with placebo ( HR 1.03 , 95 % CI 0.78 - 1.37 , and 1.00 , 0.74 - 1.34 , respectively ) . There were no significant differences in the attack rates for diarrhoea , dysentery , or respiratory infections between groups , although all the relative risks except one indicated modest , non-significant protective effects . INTERPRETATION Daily supplementation of young children in southern Nepal with iron and folic acid with or without zinc has no effect on their risk of death , but might protect against diarrhoea , dysentery , and acute respiratory illness Previous data from Vietnam show that anaemia is highly prevalent among schoolchildren , who are considered not to be iron deficient . Trichuris infection doubled the risk of anaemia . The present study aim ed to evaluate the hypothesis that de-worming is more effective than iron fortification in an anaemic , infection-prone population . In a trial with a 2 x 2 factorial design , 425 anaemic children aged 6 - 8 years were r and omly assigned to receive either iron-fortified noodles or placebo , and mebendazole or placebo . Outcomes considered were change in haematological indicators of iron status ( Hb , serum ferritin ( SF ) , serum transferrin receptor ( TfR ) and haemoglobinopathies analysis ) ; inflammations ( C-reactive protein ( CRP ) ) ; parasite infection status ( hookworm , Trichuris and Ascaris infection ) ; and IgE. ANOVA and logistic regression were used to assess the effects of iron fortification and de-worming on Hb , SF , TfR , body iron and anaemia . Hb improved in all groups after 6 months of intervention . Iron fortification significantly improved Hb , SF and body iron ( 2.6 g/l , 16.3 microg/l and 1 mg/kg , respectively ) . Prevalence of elevated IgE was very high at baseline ( 99 % ) and significantly reduced to about 75 % in all groups after intervention . De-worming unexpectedly showed no effect on Hb , iron status and IgE level . It is concluded that iron fortification slightly improved anaemia and iron status in anaemic schoolchildren in rural Vietnam that were not considered iron deficient . Chronic infection or other unidentified factors may play an important role in the seasonal reduction of anaemia seen in all treatment groups The effectiveness of bread fortified with iron bis-glycinate chelate for the control of iron deficiency and iron deficiency anemia was evaluated in 89 preschool children from families of low socioeconomic level attending 2 day nurseries of the Sao Paulo City Council . During the intervention 's time of 6 months the children received besides their usual center 's diet , a daily supplement of two sweet rolls fortified with 2 mg each of iron from the chelate for a total daily iron intake of 4 mg . After six months of intervention there was a significant decrease in the prevalence of iron deficiency anemia from 62 to 22 % . There was a mean hemoglobin improvement of 1.1 g/dL , and in children with initial hemoglobin levels < 11 g/dL the mean increase in hemoglobin was 1.42 g/dL. The total mean plasma ferritin values increased from 11.34 to 20.2 micrograms/L , and in those children originally iron depleted the ferritin values normalized . A significant increase in the " z " score for weight/height was also observed . We concluded that the use of sweet rolls fortified with 2 mg of iron from the bis-glycinate chelate is highly effective for the control of iron deficiency and iron deficiency anemia in young children BACKGROUND The Cochrane Collaboration is strongly encouraging the use of a newly developed tool , the Cochrane Collaboration Risk of Bias Tool ( CCRBT ) , for all review groups . However , the psychometric properties of this tool to date have yet to be described . Thus , the objective of this study was to add information about psychometric properties of the CCRBT including inter-rater reliability and concurrent validity , in comparison with the Effective Public Health Practice Project Quality Assessment Tool ( EPHPP ) . METHODS Both tools were used to assess the method ological quality of 20 r and omized controlled trials included in our systematic review of the effectiveness of knowledge translation interventions  to improve the management of cancer pain . Each study assessment was completed independently by two review ers using each tool . We analysed the inter-rater reliability of each tool 's individual domains , as well as final grade assigned to each study . RESULTS The EPHPP had fair inter-rater agreement for individual domains and excellent agreement for the final grade . In contrast , the CCRBT had slight inter-rater agreement for individual domains and fair inter-rater agreement for final grade . Of interest , no agreement between the two tools was evident in their final grade assigned to each study . Although both tools were developed to assess ' quality of the evidence ' , they appear to measure different constructs . CONCLUSIONS Both tools performed quite differently when evaluating the risk of bias or method ological quality of studies in knowledge translation interventions for cancer pain . The newly introduced CCRBT assigned these studies a higher risk of bias . Its psychometric properties need to be more thoroughly vali date d , in a range of research fields , to underst and fully how to interpret results from its application Concurrent micronutrient deficiencies are prevalent among Vietnamese school children . A school-based program providing food fortified with multiple micronutrients could be a cost-effective and sustainable strategy to improve health and cognitive function of  school children . However , the efficacy of such an intervention may be compromised by the high prevalence of parasitic infestation . To evaluate the efficacy of school-based intervention using multi-micronutrient-fortified biscuits with or without deworming on anemia and micronutrient status in Vietnamese schoolchildren , a r and omized , double-blind , placebo-controlled trial was conducted among 510 primary schoolchildren , aged 6 - 8 y , in rural Vietnam .  Albendazole ( Alb ) ( 400 mg ) or placebo was given at baseline . Nonfortified or multi-micronutrient-fortified biscuits including iron ( 6 mg ) , zinc ( 5.6 mg ) , iodine ( 35 microg ) , and vitamin A ( 300 microg retinol equivalents ) were given 5 d/wk for 4 mo . Multi-micronutrient fortification significantly improved the concentrations of hemoglobin ( + 1.87 g/L ; 95 % CI : 0.78 , 2.96 ) , plasma ferritin ( + 7.5 microg/L ; 95 % CI : 2.8 , 12.6 ) , body iron ( + 0.56 mg/kg body weight ; 95 % CI : 0.29 , 0.84 ) , plasma zinc ( + 0.61 micromol/L ; 95 % CI : 0.26 , 0.95 ) , plasma retinol ( + 0.041 micromol/L ; 95 % CI : 0.001 , 0.08 ) , and urinary iodine ( + 22.49 micromol/L ; 95 % CI : 7.68 , 37.31 ) . Fortification reduced the risk of anemia and deficiencies of zinc and iodine by > 40 % . Parasitic infestation did not affect fortification efficacy , whereas fortification significantly enhanced deworming efficacy , with the lowest reinfection rates in children receiving both micronutrients and Alb . Multi-micronutrient fortification of biscuits is an effective strategy to improve the micronutrient status of Vietnamese schoolchildren and enhances effectiveness of deworming BACKGROUND Some r and omised controlled trials ( RCTs ) done in German-speaking Europe are published in international English- language journals and others in national German- language journals . We assessed whether authors are more likely to report trials with statistically significant results in English than in German . METHODS We studied pairs of RCT reports , matched for first author and time of publication , with one report published in German and the other in English . Pairs were identified from reports round in a manual search of five leading German- language journals and from reports published by the same authors in English found on Medline .  Quality of methods and reporting were assessed with two different scales by two investigators who were unaware of authors ' identities , affiliations , and other characteristics of trial reports . Main study endpoints were selected by two investigators who were unaware of trial results . Our main outcome was the number of pairs of studies in which the levels of significance ( shown by p values ) were discordant . FINDINGS 62 eligible pairs of reports were identified but 19 ( 31 % ) were excluded because they were duplicate publications . A further three pairs ( 5 % ) were excluded because no p values were given . The remaining 40 pairs were analysed . Design characteristics and quality features were similar for reports in both language s. Only 35 % of German- language articles , compared with 62 % of English- language articles , reported significant ( p < 0.05 ) differences in the main endpoint between study and control groups ( p = 0.002 by McNemar 's test ) . Logistic regression showed that the only characteristic that predicted publication in an English- language journal was a significant result . The odds ratio for publication of trials with significant results in English was 3.75 ( 95 % CI 1.25 - 11.3 ) . INTERPRETATION Authors were more likely to publish RCTs in an English- language journal if the results were statistically significant . English language bias may , therefore , be introduced in review s and meta-analyses if they include only trials reported in English . The effort of the Cochrane Collaboration to identify as many controlled trials as possible , through the manual search of many medical journals published in different language s will help to reduce such bias OBJECTIVE Compare milk-based , iron-fortified formulas containing 7.4 and 12.7 mg/L iron and breast-feeding during the first year of life . DESIGN Partially r and omized , double-blind trial : non-breast-fed infants r and omly assigned to receive one of two coded formulas , identical except for iron content ; infants discontinuing breast-feeding between 1 and 8 weeks of age r and omly assigned to a formula late-start group . SETTING Five general community pediatric practice s in Missouri , Indiana , Illinois , and Pennsylvania . PARTICIPANTS Sample of 347 healthy , term infants , enrolled within 1 week after birth ; 172 included in statistical analyses . OUTCOME MEASURES Length , weight , and indicators of formula intolerance recorded at clinic visits ; formula consumption , bowel movements , stool consistency , and other tolerance indicators recorded by parents on daily and weekly report forms ; hemoglobin , hematocrit , and serum ferritin , iron zinc , and copper measured at 6 and 12 months . RESULTS No significant differences between formula-fed groups in growth , attrition , formula consumption , bowel movements , hematocrit , hemoglobin level , and serum iron , zinc , and copper levels ( P > .05 ) ; first 6-month weight and length changes of the breast-fed group significantly less than in both formula-fed groups ( P < .008 ) ; serum ferritin level of the formula-fed , high-iron group significantly higher than that of the low-iron and breast-fed groups ( P < .008 ) , although all groups ' values were normal ; no apparent differences between formula groups in formula tolerance and stool characteristics but data were not analyzed statistically . CONCLUSIONS Milk-based formulas containing either 7.4 or 12.7 mg/L iron support normal growth and iron status of healthy , term , normally fed infants during the first year and both are well tolerated and accepted 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-r and omized 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 sample s 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
