“…Newbom with birth weight < 2500 gm showed relatively greater oxidative stress measured by their MDA levels. A similar increase in peroxidative stress in low birth child has also been reported by Baydas et al (18).…”

Serum antioxidant status and peroxidative stress was estimated in 30 pregnant women, their newborn infants and 25 non-pregnant women. Serum Ascorbic acid, cr retinol & ~-carotene levels were found to be significantly reduced and peroxidatlve stress was significantly higher in mothers as compared to matched non-pregnant women. Newborn had significantly higher levels of ascorbic acid as compared to their mother but had significantly lower levels of lipid soluble vitamins. The peroxidative stress in newbom was found to be significantly less as compared to their mothers. A positive correlation of ascorbic acid and ct-tocopherol levels between mother and newborn reflects that their status in mother does influence the newborn status.

“…When mothers at risk of preterm delivery were supplemented with b-carotene and vitamins C and E, the plasma malondialdehyde level was significantly lower than in control mothers at delivery (Bolisetty et al, 2002). When the status of vitamins C and E in cord blood was compared, preterm babies had lower concentrations of vitamins C and E than term babies did (Guajardo et al, 1995;Baydas et al, 2002). However, there has been little research on the effect of the levels of vitamins C and E in pregnant women on fetal growth.…”

Objective: It has been known that maternal oxidative stress during pregnancy plays an important role in fetal growth. However, the association between antioxidant vitamin levels and birth outcomes is not conclusive. We investigated the relationship between maternal serum levels of vitamins C and E during the second trimester and birth weight and length. Design: Prospective cohort study. Setting: Outpatient-clinic of obstetrics, Ewha Womans University Hospital, South Korea. Subjects and methods: The study subjects were 239 healthy, pregnant women who visited an obstetric clinic for antenatal care, and their singleton live births, in Seoul, Korea, between August 2001 and March 2003. We measured the levels of vitamins C and E in maternal serum during the period 24-28 gestational weeks. Each woman was interviewed for dietary intake by trained interviewers during the second trimester. Results: The serum concentration of maternal vitamin C during the second trimester was significantly associated with birth weight and length in the group of full-term deliveries. An increase of 1 mg/ml in the serum vitamin C level increased the birth weight by 27.2 g and the birth length by 0.17 cm. When we considered the levels of vitamins C and E together in the relationship with birth weight and length, we found that the heaviest birth weight and the longest birth length belonged to the group of upper vitamin C/ upper vitamin E. However, dietary intake estimated by 24-h recall method was not a predictor of the levels of serum vitamins C and E. Conclusion: We found that maternal serum vitamin C levels during the second trimester were positively correlated with birth weight and length in full-term babies. We also found that birth weight and length were highest when the levels of both vitamins C and E were high. Our results indicate the importance of antioxidant nutrient balance for pregnant women who are exposed to various oxidants through food, drinking water, or inhaled air.

“…18 These values represent an important indicative for the health of the binomial, since there is evidence that alpha-tocopherol maternal serum is directly related to the neonate. 19,20 An insufficient supply of vitamin E for the fetus can cause DVE and result in compromising the immune system and lungs, as well as becoming likely to develop after birth hemolytic anemia. 6 Although most of the participants of this study are in social vulnerability conditions (Table 1), and probably more exposed to micronutrient deficiency, only 6% (n=6) presented DVE.…”
