A surge in the risk of spontaneous abortion is associated with generous consumption of caffeinated beverages before pregnancy.

‚ÄčThis study assessed the effect of the intake of caffeinated beverages before pregnancy on a woman's risk of suffering from spontaneous abortion. With the aid of validated questionnaires, researchers collated and analyzed data on the beverage drinking habits of 11,072 pregnant women. All incidents of spontaneous abortion during the study period were also recorded. 

Researchers noticed a high rate of spontaneous abortion among women who consumed generous amounts of caffeinated beverages before pregnancy. Pre-pregnancy consumption of 4 or more servings of coffee per day was found to increase the risk of spontaneous abortion by 20% in this study. The data from this study show that lovers of caffeinated beverages may have a high propensity to suffer from spontaneous abortion during pregnancy.
