Caffeine
in Pregnancy
The Associated Press
Dec. 20
— Five cups of coffee per day more than doubles a pregnant
woman’s risk of a miscarriage, according to perhaps the
most rigorous study yet to focus on the possible link
between caffeine and miscarriage.
Some studies
suggest that modest caffeine intake of less than two average 9 oz.
cups of brewed coffee presents a slight risk to the embryo or
fetus, but others do not. However, there is stronger evidence that
larger daily amounts of caffeine during pregnancy may increase the
risks of miscarriage, preterm delivery and low birth weight, but
there is still no solid proof of this.
Why risk it? Avoid moderate amounts of caffeine during
pregnancy.
Caffeine’s Effects on
Fertility  According to Hatch EE, Bracken MB (1993). Association of
delayed conception with caffeine consumption. American Journal of
Epidemiology, 138(12), 1082-092,
some st udies have found a link between high
levels of caffeine consumption by women and delayed conception.
Those who consumed more than 300 mg of caffeine per day were
twice as likely to have conception delayed for a year or more.
Another
study also linked high caffeine intake to delayed conception, but
only in women consuming 500 mg or more (about four cups of coffee)
per day.
