Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Delayed cord clamping until the cord stops pulsating (at least 1 minute and no more than 3 minutes after delivery) with baby held below level of placenta or vaginal introitus. If there are complications that arise with the delivery or the baby is in distress at birth, immediate cord clamping is done to allow for neonatal resuscitation.

Other interventions
Comparator / control treatment
Immediate cord clamping soon after birth (within 1 minute after delivery).
Control group
Active

Secondary outcome [7] 294999 0
effect on Indigenous Cord Blood Collection Program by measuring the total placental volume after delayed cord clamping and comparing this volume to the amounts collected after immediate cord clamping to detect any significant difference that will affect the program's usual volume collected primarily after immediate cord clamping. These volumes will be recorded in a data collection sheet.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
pregnant Aboriginal women usually resident in a remote Aboriginal community at 36 to 42 weeks gestation who are expected to give birth by uncomplicated normal vaginal delivery or elective Caesarian section will be consented. Randomization will be done by by investigators or midwifery team present during the second stage of labour. Allocation concealment will be achieved by the use of sequentially numbered sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer-generated randomization sequence will be prepared by an independent statistician at NHMRC Clinical TrialsCentre. The randomization code will be stored securely by the NHMRC Clinical Trials Centre. The allocation sequence will be concealed from all investigators, staff and participants throughout the study.

Summary
Brief summary
Anaemia is prevalent among Aboriginal infants under 12 months old. Delayed cord clamping is a simple way to provide extra blood to the newborn baby. Strong evidence from randomized controlled trials has shown its benefits for neonatal health and reducing anaemia in early infancy. The beneficial effects on Aboriginal infants and beyond the first 6 months of life are still unknown. It is clinically important to determine if this simple intervention at birth will impact greatly the health of remote Aboriginal infants with high risk of anaemia due to poor access to nutrition later in infancy.
This RCT will enroll 72 Aboriginal pregnant women from remote aboriginal communities who will give birth at 36-42 weeks gestation by uncomplicated NVD or CS. They will be randomly assigned to either receive the interventional delayed cord clamping until the cord stops pulsating or up to 3 minutes with baby held below level of placenta or vaginal introitus or the standard care immediate cord clamping soon after birth under 1 minute. The primary research question is whether haemoglobin level at discharge is greatest in babies after delayed cord clamping.
