Low Intake of Vitamin C Increases Risk of Pregnancy Complications
Women with low intakes of vitamin C before and during pregnancy have an
increased risk of preterm delivery compared with women taking higher
amounts, according to a new study in the American Journal of Obstetrics and
Gynecology (2003;189:519-25). Healthnotes Newswire (November 13, 2003)
The normal time from conception to birth in humans is between 37 and 41
weeks. Births that occur less than 37 weeks after conception are considered
to be preterm. Preterm delivery occurs in 8 to 16% of single-child births.
There are several known causes of preterm delivery but premature rupture of
the membranes (PROM) is the most common.
Rupture of the membranes of the fetal sac normally occurs early in labor.
When it precedes the onset of labor by more than one hour, it is known as
PROM, and is associated with 30 to 40% of preterm deliveries. Several
nutrients, including magnesium, copper, and vitamin C, are important for
maintaining the strength of the membranes. Previous studies have found that
low levels of vitamin C in maternal blood and amniotic fluid can contribute
to weaker membranes. There are no previous studies examining the
relationship between vitamin C intake and preterm PROM.
The current study analyzed the vitamin C intake and pregnancy outcomes for
2,064 women. All of the women entered the study at between 24 and 29 weeks
past conception. They answered questions about their dietary habits,
lifestyle habits, and supplement use both before and during pregnancy.
Vitamin C intake from food and supplements was calculated based on these
answers. The average total vitamin C intake among the participants was 124
mg per day before conception and 251 mg per day in the second trimester.
Women with vitamin C intake in the tenth percentile or lower had an average
total intake of 24 mg per day before conception and 112 mg per day in the
Women in the tenth percentile or lower for intake of vitamin C either
before or during pregnancy were found to have a significantly increased
risk of preterm delivery due to PROM, compared with women with higher
intake; the greatest increase in risk, however, was found in women whose
intake was low both before and during pregnancy.
The results of this study suggest that very low intake of vitamin C is
associated with increased risk of preterm births due to PROM. Moreover,
they suggest that the amount and cost of supplemental vitamin C needed to
reduce the risk of preterm delivery due to PROM would be minimal. Further
studies are needed to confirm this relationship and to identify the effect
of higher intake of vitamin C on pregnancy outcomes.
