Abstract [en]

Oxidative stress is suggested as a potential mechanism in impaired foetal growth, smaller birth size and thus subsequently adult chronic diseases. We have investigated associations between oxidative stress in pregnancy and birth anthropometry (weight, height, head and chest circumferences). In the MINIMat-trial (Maternal and Infant Nutrition Interventions, Matlab) in rural Bangladesh, free 8-iso-prostaglandin P-2 alpha (lipid peroxidation) was analysed in pregnancy week 14 and 30 and 8-Hydroxy-2 '-Deoxyguanosine (DNA oxidation) in week 19. We found that higher levels of lipid peroxidation in early pregnancy were associated with larger infant size (birth length and chest circumference). In late pregnancy, no clear pattern of associations was found. Increasing level of DNA oxidation was associated with lower birth length in girls but no other associations were found. In conclusion, a higher level of lipid peroxidation in early (but not late) pregnancy was associated with a favourable larger birth size suggesting that timing of lipid peroxidation is of importance.

Abstract [en]

Undernutrition and oxidative stress in fetal life and infancy may lead to adverse health outcomes in the offspring. We studied nutrition and oxidative parameters in pregnancy and their associations with birth anthropometry and metabolic status in the children.

In Matlab in rural Bangladesh, women were randomized to either early (Early) invitation to food supplementation or to start at their own liking (Usual). Women were also allocated to either; 1) 60 mg iron and 400 µg folic acid (Fe60F), 2) multiple micronutrients including 30 mg iron and folic acid (MMS), or 3) 30 mg iron and folic acid (Fe30F). Micronutrients (hemoglobin, iron, zinc, folic acid, vitamin B-12) were assessed in pregnancy week 14, lipid peroxidation in week 14 and 30, and DNA oxidation in week 19. The offspring were assessed for anthropometric measurements at birth and metabolic status at 4.5 years.

Micronutrient deficiencies were common with zinc and vitamin B-12 deficiency being most prevalent. Anemia was present in approximately one third of women, however, iron deficiency was uncommon seen in only 2%.

Maternal Early food supplementation group resulted in an improved lipid status in the children at 4.5 years compared to Usual food group. Prenatal use of MMS lowered the children’s glucose, insulin, HOMA-IR, and growth factors compared to Fe60F.  

Lipid peroxidation in early pregnancy was associated with size at birth and insulin and HOMA-IR levels in the children. Lipid peroxidation in late pregnancy, however, was associated with the children’s lipid status. Both increasing lipid peroxidation and increasing DNA oxidation was associated with decreasing IGF-1 levels. 

The beneficial effects of an Early start of food supplementation show that an improved prenatal nutrition may have lasting effects in the offspring and highlights the importance of early timing food supplementation. Use of MMS, however, resulted in lower insulin levels, which, considering the already low level of insulin in these children, may be a cause of concern. MMS also resulted in growth factors indicative of slower growth and further research appears to be needed before scaling up the use of MMS. Oxidative parameters in pregnancy were associated with longer-term outcomes in the offspring, suggesting that oxidative stress may be involved in the development of later metabolic disease.
