Synthesized evidence indicates that addition of multiple micronutrients to Fe supplementation may only marginally improve Hb response compared with Fe supplementation alone .
However , addition of ' other micronutrients ' may have a negative effect .
Routine addition of unselected multiple micronutrients to Fe therefore appears unjustified for nutritional anaemia control programmes
OBJECTIVES To study the effect of combining multiple ( two or more ) micronutrients with Fe supplementation on Hb response , when compared with placebo and with Fe supplementation , in children .
The effect of a micronutrient-fortified complementary food on micronutrient status, growth and development of 6- to 12-month-old disadvantaged urban South African infants
The study was conducted to look at the effectiveness of a multimicronutrient-fortified complementary food on the micronutrient status , linear growth and psychomotor development of 6- to 12-month-old infants from a black urban disadvantaged community in the Western Cape , South Africa . The study was design ed as an intervention study . In both the experimental and control groups , serum retinol concentration showed a decline over the intervention period of 6 months . The decline was less pronounced in the experimental group . This result ed in a significantly ( P<005 ) higher serum retinol concentration at 12 months in the experimental group ( 26.8±5.8 μg/dl ) compared with the control group ( 21.4±5 μg/dl ) . Serum iron concentration also declined over the intervention period . The decline was less pronounced in the experimental group . No difference was observed in haemoglobin levels between the groups at 12 months . Serum zinc concentration did not differ significantly between the two groups at follow up . Weight gain over the 6 months period did not differ significantly between the experimental ( 2.1±0.9 kg ) and control groups ( 2.1±1.2 kg ) . There was no difference in linear growth between the experimental ( 10.0±1.5 cm ) and control group ( 10.1±2.1 cm ) at the end of the follow-up period . Weight and length at 6 months significantly predicted weight and length at 12 months . No difference was observed in psychomotor developmental scores between the two groups after 6 months of intervention . Introducing a multimicronutrient-fortified complementary food into the diet of 6- to 12-month-old infants seemed to have an arresting effect on declining serum retinol and iron concentration in the experimental group . No benefit was observed in serum zinc concentration , linear growth and psychomotor development
