Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized double-blind placebo controlled intervention study with pregnant obese women (n=440) will be conducted. The intervention will involve consumption of fish oil and/or probiotic capsules from early pregnancy until 6 months after delivery.

The aim of the study is firstly to investigate the effects of the supplements on the risk of gestational diabetes mellitus and obesity in the women and secondly to modify the risk markers of allergy and obesity in children of the women. Also the underlying metabolic mechanisms will be investigated.

Follow up visits at child's age of 5 to 6 years will be conducted to evalute long-term effects on maternal and child health. The aim is to investigate the impact of dietary intervention, diet, maternal overweight/obesity and gestational diabetes status as well as gut microbiota and metabolism during pregnancy on maternal and child's health, allergy and child neuropsychological development.
