Study summary

The initial trial examined if fish oil supplementation during pregnancy could reduce the risk of pregnancy induced hypertension, intrauterine growth retardation, and preterm birth in pregnancies that were at increased risk of these complications. The study was designed as a multi-centre clinical trial based in 19 hospitals in seven countries in Europe.

Inclusion criteria

  • There were six subgroups with different inclusion criteria:
  • The low dose (prophylactic) section enrolled women who after 16 weeks of gestation had been identified with an uncomplicated pregnancy, who in an earlier pregnancy had experienced preterm delivery (this was subgroup 1)
  • Intrauterine growth retardation (subgroup 2) or pregnancy induced hypertension (subgroup 3)
  • Women who had been identified with twin pregnancies (subgroup 4)
  • The high dose ('therapeutic') section enrolled women with threatening pre-eclampsia (subgroup 5) or suspected intrauterine growth retardation in the current pregnancy (subgroup 6).

Exclusion criteria

Exclusion Criteria:

  • Diabetes mellitus in or before pregnancy
  • Diagnosed severe fetal malformation or hydrops in current pregnancy
  • Suspicion in current pregnancy, or occurrence in an earlier pregnancy, of placental abruption
  • Drug or alcohol abuse
  • Regular intake of fish oil or of non-steroidal antiinflammatory agents or other drugs with an effect on thombocyte function or eicosanoid metabolism
  • Allergy to fish products.

What researchers measure

Primary outcomes

  1. Pregnancy Induced Hypertension

    One or more recorded measurements of a diastolic blood pressure of above 90 mmHg at rest

    Time frame: Participants will be followed for the duration of pregnancy and the first few days after delivery, on average 20-26 weeks from recruitment and randomization.

  2. Intrauterine growth retardation

    Birth weight below the 10th centile, as assessed from the infant's birth weight, gestational age and gender, on the basis of Danish standards (Br J Obstet Gynaecol 1986; 93: 128-134; and Acta Obstet Gynecol Scand 1985; 64: 65-70).

    Time frame: Participants will be followed for the duration of pregnancy and the first few days after delivery, on average 20-26 weeks from recruitment and randomization.

  3. Preterm delivery

    Delivery at an estimated gestational age of less than 259 days (37 completed weeks)

    Time frame: Participants will be followed for the duration of pregnancy and the first few days after delivery, on average 20-26 weeks from recruitment and randomization.
