Study summary

Pregnant women are randomised to supplementation with fish oil, methyl tetrahydro folic acid, both or a placebo during the second half of pregnancy. Biochemical measures are determined in maternal blood during pregnancy and in cord blood.

Non invasive follow up examinations of infants at ages 4, 5.5, 6.5, 7.5, 8, 9 and 9.5 years focus on long term effects of supplementation anthropometric development, neurological development and allergy risk.

What researchers measure

Primary outcomes

  1. percentage contribution of docosahexaenoic acid (DHA) to total phospholipid fatty acids in cord blood

    the biochemical efficacy of supplementation during pregnancy is tested by measuring the DHA content of cord blood phospholipids, as direct supplementation (fish oil) or increased perfusion of the placenta (MTHF) could both influence this parameter

    Time frame: labour

Secondary outcomes

  1. neurological and cognitive development of the offspring

    non invasive, age adequate, tests of neurological and cognitive function are performed at various ages of the offspring

    Time frame: age 4 years, 5.5 years, 6.5 years, 7.5 years, 8 years, 9 years, 9.5 years

  2. weight development

    body weight (including weight of fat and non fat mass by bioelectrical impedance at later ages) is determined

    Time frame: age 4 years, 5.5 years, 6.5 years, 8 years, 9.5 years

  3. height

    body height is measured at ages 4 years, 5.5 years, 6.5 years, 8 years, 9.5 years

    Time frame: age 4 years, 5.5 years, 6.5 years, 8 years, 9.5 years

  4. life style and diet

    information on medical history, life sytyle and dietary habits is collected via questionnaires and non invasivly collected of biological samples (urine, cheek cells)

    Time frame: age 4 years, 5.5 years, 6.5 years, 7.5 years, 8 years, 9 years, 9.5 years

  5. electroencephalography (EEG)

    at age 8 years and 9.5 years an EEG is obtained while the children are performing defined tests

    Time frame: age 8 years and 9.5 years
