    Input: Background / Objectives : Zinc is an essential micronutrient and deficiency can lead to an increased risk for infectious diseases and growth retardation among children under 5 years of age . We aim ed to estimate disease-specific and all-cause mortality attributable to zinc deficiency . Subject/ Methods : We estimated the prevalence of zinc deficiency in Latin America , Africa and Asia , where based on zinc availability in the diet and childhood stunting rates , zinc deficiency is widespread . The relative risks of death among zinc-deficient children for diarrhea , malaria and pneumonia were estimated from r and omized controlled trials . We used the comparative risk assessment methods to calculate deaths and burden of disease ( measured in disability-adjusted life years , DALYs ) from each of these three diseases attributable to zinc deficiency in these regions . Results : Zinc deficiency was responsible for 453 207 deaths ( 4.4 % of childhood deaths ) , and 1.2 % of the burden of disease ( 3.8 % among children between 6 months and 5 years ) in these three regions in 2004 . Of these deaths , 260 502 were in Africa , 182 546 in Asia and 10 159 in Latin America . Zinc deficiency accounted for 14.4 % of diarrhea deaths , 10.4 % of malaria deaths and 6.7 % of pneumonia deaths among children between 6 months and 5 years of age . Conclusions : Zinc deficiency contributes to substantial morbidity and mortality , especially from diarrhea .  Zinc supplementation provided as an adjunct treatment for diarrhea may be the best way to target children most at risk of deficiency BACKGROUND Dietary supplements providing physiologic amounts of several micronutrients simultaneously have not been thoroughly tested for combating micronutrient deficiencies . OBJECTIVE We determined whether a beverage fortified with 10 micronutrients at physiologic doses influenced the iron and vitamin A status and growth of rural children ( aged 6 - 11 y ) attending primary schools . DESIGN In this r and omized , double-blind , placebo-controlled efficacy trial , children were assigned to receive the fortified beverage or an unfortified beverage at school for 6 mo . RESULTS There were nonsignificant differences at baseline between children in the fortified and nonfortified groups in iron status , serum retinol , and anthropometry . At the 6-mo follow-up , among children with anemia ( hemoglobin < 110 g/L ) , there was a significantly larger increase in hemoglobin concentration in the fortified group than in the nonfortified group ( 9.2 and 0.2 g/L , respectively ) . Of those who were anemic at baseline , 69.4 % in the nonfortified group and 55.1 % in the fortified group remained anemic at follow-up ( RR : 0.79 ) , a cure rate of 21 % . The prevalence of children with low serum retinol concentrations ( < 200 microg/L ) dropped significantly from 21.4 % to 11.3 % in the fortified group compared with a nonsignificant change ( 20.6 % to 19.7 % ) in the nonfortified group . At follow-up , mean incremental changes in weight ( 1.79 compared with 1.24 kg ) , height ( 3.2 compared with 2.6 cm ) , and BMI ( 0.88 compared with 0.53 ) were significantly higher in the fortified group than in the nonfortified group . CONCLUSION The fortified beverage significantly improved hematologic and anthropometric measurements and significantly lowered the overall prevalence of anemia and vitamin A deficiency The effects of supplementation of the diets of 6- to 12-year-old children in a village near Shiraz in Iran with  zinc plus iron or iron alone , together with the indispensable amino acids in the form of egg white protein , vitamins , minerals , and corn oil have been evaluated . Initially 48 of 59 children had zinc concentrations  below the minimum found in well-nourished persons . Eight months of supplementation with zinc plus iron ( 20 mg daily of elemental zinc as carbonate and 20 mg ferrous iron as fumarate ) failed to stimulate growth or bone development or to bring about an increase in plasma zinc concentrations . However , supplementation with iron in the above amount was associated with an acceleration of growth in height and weight . The persistence of low concentrations of zinc in plasma and the failure of supplemental zinc to stimulate growth are attributed to the poor availability of both dietary and supplemental zinc result ing from sequestering action of fiber and phytate present in large amounts in the unleavened whole meal bread consumed by villagers . In addition , the results suggest that simultaneous administration of iron and zinc supplements may impair utilization of the metals Anemia and co-existing deficiencies of zinc , iron , iodine , and vitamin A occur among children in many developing countries including NE Thail and , probably contributing to impairments in growth , immune competence , and cognition . Sustainable strategies are urgently required to combat these deficiencies . We assessed the efficacy of a micronutrient-fortified seasoning powder served with a school lunch on reducing anemia and improving the micronutrient status of rural NE Thai children . Children ( n = 569 ) aged 5.5 - 13.4y from 10 schools were r and omly assigned to receive a seasoning powder either unfortified or fortified with zinc ( 5 mg ) , iron ( 5 mg ) , vitamin A ( 270 microg ) , and iodine ( 50 microg ) ( per serving ) and incorporated into a school lunch prepared central ly and delivered 5 d/wk for 31 wk . Teachers monitored school lunch consumption . Baseline and final micronutrient status , hemoglobinopathies , and infection or inflammation were assessed from blood and urine sample s. For the primary outcome , anemia ( based on hemoglobin ) , no intervention effect was apparent ( odds ratio : 1.02 95 % CI : 0.69 , 1.51 ) after adjustment for design strata . The odds of zinc ( based on serum zinc ) and urinary iodine deficiency in the fortified group were 0.63 ( 0.42 , 0.94 ) and 0.52 ( 0.38 , 0.71 ) times those in the unfortified group , respectively . Fortification had no effect on serum retinol ( 0.61 : 0.25,1.51 ) , ferritin ( 1.12 : 0.43 , 2.96 ) , or mean red cell volume ( 1.16 : 0.82 , 1.64 ) . Therefore , a micronutrient-fortified seasoning powder is a promising vehicle for improving zinc , iodine , and hemoglobin status , and its potential for incorporation into lunch programs in day care centers and schools in NE Thail and warrants investigation Due to their widespread acceptability , multinutrient-fortified foods and beverages may be useful in reducing micronutrient deficiencies , especially in developing countries . We studied the efficacy of a new fortified beverage in improving the nutritional status of children in Botswana . We screened 311 lower income urban school children , ages 6 - 11 y , in two primary schools near Gaborone . Children were given seven 240-mL servings weekly of either an experimental beverage ( EXP ) fortified with 12 micronutrients or an isoenergetic placebo drink ( CON ) for 8 wk . Weight , mid-upper arm circumference , hemoglobin , retinol , ferritin , vitamin B-12 , folate and riboflavin status were measured at baseline and at the end of the study . Plasma zinc and serum transferrin receptors also were measured at study end . A total of 145 children in the EXP group and 118 in the CON group completed the trial . Using multivariate analysis , the changes in mid-upper arm circumference , weight for age and total weight were significantly better in the EXP group than in the CON group ( P < 0.01 ) . Ferritin , riboflavin and folate status were significantly better in the EXP group than in the CON group at study end ( P < 0.01 ) , but serum vitamin B-12 was not . Zinc was significantly higher and transferrin receptors were significantly lower at the conclusion of the study in the EXP group than in the CON group ( P < 0.001 ) . Mean plasma retinol concentrations , which were low ( < 0.7 micro mol/L ) in both groups , did not change . We conclude that a micronutrient-fortified beverage may be beneficial as part of a comprehensive nutritional supplementation program in population s at risk for micronutrient deficiencies BACKGROUND Reductions in iodine and zinc deficiencies and improvements in hemoglobin were achieved from a micronutrient-fortified seasoning powder consumed in school lunches by children in northeast Thail and . OBJECTIVE The objective was to determine whether fortification with 4 micronutrients in a school lunch results in changes in children 's growth , morbidity , and cognitive function compared with no fortification . DESIGN In a r and omized controlled trial of 569 children aged 5.5 - 13.4 y from 10 schools , we compared the efficacy of a seasoning powder fortified with or without 5 mg Fe , 5 mg Zn , 50 mug I , and 270 mug vitamin A per serving consumed with a school lunch 5 d/wk . Here we report on results of the secondary functional outcomes . RESULTS The groups were comparable concerning compliance and loss to follow-up . The intervention had no statistically significant effect on anthropometric measures over 31 wk , but reduced the incidence of respiratory-related illnesses [ rate ratio ( RR ) : 0.83 ; 95 % CI : 0.73 , 0.94 ] , symptoms of runny nose ( RR : 0.80 ; 95 % CI : 0.70 , 0.92 ) , cough ( RR : 0.80 ; 95 % CI : 0.66 , 0.96 ) , and diarrhea ( RR : 0.38 ; 95 % CI : 0.16 , 0.90 ) . For the visual recall test , those in the fortified group recalled 0.5 more items ( 95 % CI : 0.1 , 0.9 ) than did the controls . There were no statistically significant differences between groups in the results of the digits forward and backward tests or in school grade s at the conclusion of the 2 semesters . CONCLUSION The beneficial effects on morbidity and visual recall over a short period , in addition to some biochemical improvements , highlight the potential of this micronutrient-fortified seasoning powder supplied in a school lunch . This trial was registered at clinical trials.gov as ACTRN12605000341628 BACKGROUND Little is known about the combined effect of micronutrients and essential fatty acids on cognitive function in school-aged children . OBJECTIVE We assessed the effect of micronutrients , long-chain n-3 fatty acids , or both on indicators of cognitive performance in well-nourished and marginally nourished school-aged children . DESIGN Two 2-by-2 factorial r and omized controlled double-blind trials were performed home-based in Adelaide , South Australia , and at 6 primary schools in Jakarta , Indonesia . A total of 396 children ( aged 6 - 10 y ) in Australia and 384 children in Indonesia were r and omly allocated to receive a drink with a micronutrient mix ( iron , zinc , folate , and vitamins A , B-6 , B-12 , and C ) , with docosahexanoic acid ( DHA , 88 mg/d ) and eicosapentaenoic acid ( EPA , 22 mg/d ) , or with both or placebo 6 d/wk for 12 mo .  Biochemical indicators were determined at baseline and 12 mo . Cognitive performance was measured at baseline , 6 mo , and 12 mo . RESULTS The micronutrient treatment significantly improved plasma micronutrient concentrations in Australian and Indonesian children . DHA+EPA treatment increased plasma DHA and total plasma n-3 fatty acids in both countries . The micronutrient treatment result ed in significant increases in scores on tests representing verbal learning and memory in Australia ( estimated effect size : 0.23 ; 95 % CI : 0.01 , 0.46 ) . A similar effect was observed among Indonesian girls ( estimated effect size : 0.32 ; 95 % CI : -0.01 , 0.64 ) . No effects were found on tests measuring general intelligence or attention . No effects of DHA+EPA on the factors of cognitive tests were observed . CONCLUSION In well-nourished school-aged children , fortification with multiple micronutrients can result in improvements in verbal learning and memory Maternal malnutrition continues to be a major contributor to adverse reproductive outcomes in developing countries , despite longst and ing efforts to fortify foods or to distribute medicinal supplements to pregnant women . The objective of this study was to test the effect of a micronutrient-fortified beverage containing 11 micronutrients ( iron , iodine , zinc , vitamin A , vitamin C , niacin , riboflavin , folate , vitamin B-12 , vitamin B-6 and vitamin E ) on the hemog
