Iron supplementation improves mental development score modestly .
This effect is particularly apparent for intelligence tests above 7 years of age and in initially anaemic or iron-deficient anaemic subjects .
There is no convincing evidence that iron treatment has an effect on mental development in children below 27 months of age or on motor development
OBJECTIVE To evaluate the effect of iron supplementation on  mental and motor development in children through a systematic review of r and omised controlled trials ( RCTs ) .
Effects of an energy and micronutrient supplement on play behavior in undernourished children in Indonesia
Objectives : This paper reports the effects of an energy and micronutrient supplementation on quantitative and qualitative aspects of play among poorly nourished children . At issue is whether the supplement led to a progression in complexity of play . Design : two cohorts of children were r and omly assigned to three treatments : E=1171 kJ+12 mg iron ; M=12 mg iron+209 kJ ; S=104 kJ. Supplementation was given for 6 months . Evaluations of play behavior were repeated four times . Setting : The sites were six tea plantations in Pangalengan , West Java . Subjects : The present study utilized a sub sample of 55 children recruited for the larger Pangalengan project 6 months into the study . Thirty-eight children were recruited late enough to allow for longitudinal observations . The remaining cases were used for cross sectional observations only . Inclusion criteria were : no chronic disease ; length-for-age ≤−1 st and ard deviation ( s.d . ) and weight-for-length between −1 and −2 s.d . of the median of the reference of the World Health Organization . Methods : The children were videotaped during play . These tapes were coded for eight mutually exclusive categories of activities . Four activities coded represented manipulative , relational , functional and symbolic play . Results : Treatment did not affect qualitative play . Girls that received E increased functional play but boys showed the opposite effect . Children in the S group were breastfed more during play as compared to the E group . Children in the E group waited less to begin play . Sponsorship : Nestlé Foundation . European Journal of Clinical Nutrition ( 2000 ) 54 , Suppl 2 ,
