Caffeine and caffeinated beverage consumption and risk of spontaneous abortion.

ABSTRACT:

Study question

Is caffeine and caffeinated beverage consumption associated with the risk of spontaneous abortion (SAB)?

Summary answer

While preconceptional caffeine consumption was not materially associated with an increased risk of SAB, consumption during early pregnancy was associated with a small increased risk of SAB, although the relation was not linear.

What is known already

Caffeine has been hypothesized as a risk factor for SAB since the 1980s; however, results from previous studies have been conflicting.

Study design, size, duration

This prospective cohort study included 5132 Danish women planning pregnancy and enrolled from 2007 to 2010.

Participants/materials, setting, methods

Participants were women who conceived after entry into the Snart-G
