Plain English summary of protocol

Background and study aims
Iron supplementation is an important public health intervention. However, in areas where malaria is common, iron supplementation may not be without risk because iron can stimulate the growth of malaria parasites. The aim of this study is to compare the incidence of malaria between children given iron supplementation and children not given iron supplementation.

Who can participate?
School age children (6-18 years old) tested as not infected with malaria.

What does the study involve?
The children will be randomly allocated to receive Albendazole (a drug to treat infections caused by worms) for three consecutive days in combination with either iron supplementation or a matching placebo (dummy drug) for 6 days per week for a total of 8 weeks.

What are the possible benefits and risks of participating?
Participants will receive anti-worm treatment for worm infections and iron treatment for their anemia. The iron tablet is given in individual doses based on body weight and under supervision of a medical doctor, so there is little or no risk of dangers from the side effects.

Where is the study run from?
Nangapanda Region, District of Ende, Flores Island, Indonesia

When is the study starting and how long is it expected to run for?
July 2011 to January 2012

Who is funding the study?
Nutricia Research Foundation (Netherlands)

Scientific titleTowards safe and effective iron supplementation in malaria endemic areas: randomized double-blind placebo controlled trial
Study objectivesIron supplementation in anemic subjects with submicroscopic malaria increases hemoglobin levels but does not increase parasitaemia.
