Study: No link between coffee drinking, pregnancy risks

A large study concluded that drinking coffee during pregnancy is NOT associated with elevated risk for adverse health outcomes.

Earlier research had suggested that coffee consumption might raise the risk of stillbirth, preterm birth or miscarriage.

Gunn-Helen Moen, PhD, a fellow at the Institute for Molecular Bioscience at the University of Queensland, Australia, told Healio. “But many of these studies have been unable to test if coffee itself is actually causing these outcomes, as this observed association could be due to other factors.”

However, this newer, much larger study of data from the Coffee and Caffeine Genetics Consortium and other sources, found that coffee consumption did not increase the risk for:

  • miscarriage,
  • stillbirth,
  • preterm birth, and
  • birth weight.

Of note, the study reported that drinking more coffee was associated with a higher birth weight, but the magnitude of the effect was inconsistent, according to the researchers.

The research was published in the International Journal of Epidemiology. Read the full story at Healio (free registration)

    Would have been nice to include some of the data on coffee drinking leading to better longevity less heart disease etc.
    And BTW, I can’t recall but did I tell you about my book that’s on Amazon:
