Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Women meeting the inclusion criteria will be approached during their first antenatal visit by their treating midwife or doctor who will explain the study, give possible participants an information sheet that will outline the study and expected weight gain and consent the patient with forms approved by The Royal Women’s Hospital Research Committee. The treating doctor or midwife approaching the patient will not be directly involved in the research project. Once recruited she will be allocated an opaque envelope that will place the patient in either the intervention group or the control group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The seqeuence is computer generated. It is then placed into sealed opaque envelopes which are selected on randomisation of a patient.
Masking / blinding
Open (masking not used)
