Caffeine Intake and Pregnancy Loss

Adapted from "Caffeinated Beverage Intake and Serum Caffeine Metabolites and Risk of Pregnancy Loss" by Purdue-Smithe et al.

A new study on caffeine intake and pregnancy by a team of researchers at the National Institutes of Health was presented at the 75th Scientific Congress of the American Society for Reproductive Medicine.

The study showed that the use of any level of caffeine, particularly during the first eight weeks of pregnancy, may increase the risk of pregnancy loss.

The study was of over 1200 reproductive age women attempting pregnancy between 2007 and 2011. Researchers examined both daily self-reported intake of caffeine and blood serum caffeine levels both pre-conception and at eight weeks gestation.

Pre-conception of intake of two or more caffeinated beverages (coffee, tea, or soda) were associated with risk of pregnancy loss.

The researchers concluded that women considering pregnancy could benefit from eliminating caffeine intake.
