Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The commune was chosen as the cluster unit of randomization to reduce the likelihood of interactions between the intervention groups. All eligible women in each commune will be invited to participate in the study. The pharmaceutical manufacturer and the Chairman of the DSMC will retain the allocation code.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Communes agreeing to participate in the study will be randomly assigned to one of the three treatment arms by an independent statistician using ‘ralloc’ in the statistical program Stata (StataCorp, College Station, TX, USA).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Blinding was possible for the two arms of the study where supplements were given twice weekly.
Blinding was not possible for the supplements which were given daily (control arm).

Summary
Brief summary
In this study, we will compare the effects of three different methods of iron supplementation in 1250 pregnant Vietnamese women on maternal haemoglobin and iron stores, infant birth weight, and infant anaemia, infant height, weight and developmental screening during the first 12 months of life. We will also assess the influence of maternal depression on infant growth parameters.
