Serum retinol, alpha-tocopherol, and lipid peroxide concentrations in low-income indian pregnant mothers.
Serum alpha-tocopherol, retinol, and malondialdehyde concentrations were measured at 7(th) month of pregnancy in 122 women from low socio-economic background. Maternal anthropometric measurements, 24-hour nutrient intakes, and pregnancy outcome were recorded. One-third (34.3 %) of mothers had low birth weight babies and 10 % delivered preterm. Maternal diets were inadequate in all the nutrients, the most limiting being vitamin A. Three-fourths of mothers had intakes less than 25 % of the Indian recommended daily intake (RDI) of 600 microg retinol equivalents/day. Serum alpha-tocopherol concentrations of 98 % were indicative of deficiency and almost half the mothers had low serum retinol concentrations (< or =10 microg/dL). Mean malondialdehyde level was 7.0 +/- 1.4 nmoles/mL. These values are higher than reports in the literature and were attributable to poor intake of most dietary antioxidants. Malondialdehyde concentrations were negatively correlated with serum alpha-tocopherol. Birth weight was positively correlated with maternal weight and biceps skinfold thickness, macronutrient intakes, serum retinol, and alpha-tocopherol concentrations. Preterm delivery was associated with low anthropometric measurements and low nutrient intakes especially vitamin A. Mothers who delivered preterm had significantly lower malondialdehyde concentrations than those who delivered at term. The role of antioxidant nutrients, especially vitamin A and oxidative stress in relation to fetal growth and pregnancy outcome among mothers from low socioeconomic settings requires attention.
