Iron supplements for school children in the Philippines

There is increasing evidence that iron deficiency affects children’s ability to learn at school. Are iron supplements the answer?  And are daily or weekly supplements more effective?

The World Health Organisation (WHO) has recommended that if more than 40 percent of a country's school children are anaemic, then children should be given iron supplements. Save the Children, together with the University of Westminster, UK, carried out research into the effects of iron supplements on rural school children on the islands of Iloila and Guimaras in the Philippines. Children in 25 schools were given an iron pill each week for 10 weeks while children in another 24 schools were used as a control.  

Iron supplements are part of a wide-ranging health programme in the Philippines aimed at improving children’s educational performance. 2 age groups were targeted: children aged 7 to 8, and those aged 10 to 12.

The study found that:

Haemoglobin counts in the control group may have dropped because it was the lean season between harvests and food was scarce. The study shows that small amounts of iron given to children in areas where anaemia is considered a mild health problem may have quite long lasting effects.  For every child with anaemia, another one or two will be suffering from an iron deficiency, so many more children benefit from the supplements.

The report recommends that:

The WHO recommends iron supplements for school children on a daily basis for three months where anaemia is a major health problem. However, weekly tablets are just as effective if they are given in a supervised environment such as a school.  Even where anaemia is only a mild public health problem, weekly iron supplements given by teachers will prevent a fall in the haemoglobin count and benefit anaemic and non-anaemic children.
