    Pregnant women, especially those in lower social classes, experience declining vitamin C levels. Leucocyte ascorbic acid (vitamin C) status significantly drops postpartum, with many women falling below normal levels.

    Area of Science:

    • Nutritional biochemistry
    • Maternal-fetal medicine
    • Public health nutrition

    Background:

    • Ascorbic acid (vitamin C) is essential for maternal health during pregnancy.
    • Nutritional status during pregnancy can impact both maternal and infant outcomes.
    • Socioeconomic factors may influence nutrient intake and status in pregnant populations.

    Purpose of the Study:

    • To assess leucocyte ascorbic acid levels in pregnant women during late gestation and the early postpartum period.
    • To investigate the influence of season, maternal age, and socioeconomic status on vitamin C status.
    • To determine changes in vitamin C levels in the immediate postpartum phase.

    Main Methods:

    • Measurement of leucocyte ascorbic acid concentration in 79 pregnant women.

  • Sampling conducted during the 34th to 38th week of gestation and on postpartum days 1, 3, and 5.
  • Analysis of data stratified by season, age, and socioeconomic class (IV and V).

    • Main Results:

    • No significant differences in vitamin C levels were observed based on season or maternal age.
    • Women in lower socioeconomic classes (IV and V) exhibited significantly lower vitamin C status.
    • Leucocyte ascorbic acid levels decreased significantly by the first day postpartum, returning to baseline by day 5.
    • In late pregnancy, 40% of subjects had vitamin C levels below the normal limit (100 nmol/10(8) leucocytes), increasing to 75% on day 1 postpartum.

    Conclusions:

    • Lower socioeconomic status is associated with poorer vitamin C status in pregnant women.
    • The postpartum period is characterized by a significant decline in vitamin C levels, indicating increased vulnerability.
    • A substantial proportion of pregnant women and a majority in the early postpartum period exhibit suboptimal vitamin C status, necessitating attention to nutritional support.
