Early preterm birth (EPTB) is the major cause of perinatal mortality, serious neonatal morbidity and moderate to severe childhood disability in developed countries. Currently, effective broadly applicable primary prevention strategies to reduce the risk of EPTB in the general population are lacking. This randomised controlled trial will determine whether n-3 LCPUFA supplementation from mid-pregnancy (before 20 weeks gestation) to 34 weeks gestation reduces the risk of EPTB. The study is a double .... Read more
A singleton or multiple pregnancy and less than 20 weeks gestation. Able to give informed consent.
Women with a known fetal abnormality will be excluded. Women who are taking dietary supplements containing LCPUFA > 150mg/day. Women who are taking dietary supplements containing LCPUFA < / = 150mg/day and are not willing to stop. Women with bleeding disorders where fish oil is contraindicated or are on anticoagulant therapy. Women with a history of drug or alcohol abuse.

Sex Females
Condition category Early preterm birth
Condition code Diet and Nutrition , Reproductive Health and Childbirth
Intervention code Prevention
3 capsules of fish oil containing a total dose of approximately 800 mg of DHA will be administered orally per day until 34 weeks gestation or birth (whichever occurs first). Women will be asked to return unused supplements at the end of the 34 weeks gestation when a spot blood sample is taken. The proportion of capsules returned will serve as a measure of adherence. DHA concentration at the end of intervention will be used as an independent biomarker of adherence.
Control group Placebo
Vegetable oils with a trace of DHA to aid masking
Outcome: Evaluate the impact of fish oil supplementation on the incidence of early preterm birth compared with placebo.Timepoint: Early preterm birth defined as delivery before 34 weeks completed gestation age.

Yes. De-identified, individual participant data (IPD) that underlie the results reported in the primary paper (text, tables, figures and appendices) will be available. Dataset(s) will be limited to those participants and variables that are necessary for completion of the approved research proposal.
Data requests will be accepted beginning 3 months and ending 5 years after publication of trial results.
Data will be available to researchers who provide a methodologically sound research proposal following review and approval by the trial steering committee and completion of a signed data access agreement.
