研究概览
简要总结
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.

结局指标
主要结局
percentage contribution of docosahexaenoic acid (DHA) to total phospholipid fatty acids in cord blood
时间窗: labour
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
次要结局
- neurological and cognitive development of the offspring(age 4 years, 5.5 years, 6.5 years, 7.5 years, 8 years, 9 years, 9.5 years)
- weight development(age 4 years, 5.5 years, 6.5 years, 8 years, 9.5 years)
- life style and diet(age 4 years, 5.5 years, 6.5 years, 7.5 years, 8 years, 9 years, 9.5 years)
- height(age 4 years, 5.5 years, 6.5 years, 8 years, 9.5 years)
- electroencephalography (EEG)(age 8 years and 9.5 years)
