title: Associations between oxidative parameters in pregnancy and birth anthropometry in a cohort of women and children in rural Bangladesh: the MINIMat-cohort.
abstract: 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 F(2α) (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.
